Brain health is one of the key things that we need to protect for us to actually develop Africa in any way. Therefore the Neuroscience Institute serves as one of the first institutions that have been set up that can address local issues that affect brain health, said Rachael Dangarembizi, UCT lecturer in Neurophysiology.

The centre was conceived in 2015, and it's expected to be fully operational in May.

The idea is to get academic activities going and bring in people from a range of backgrounds, not only from the medical school and the health science faculty, but also from other campuses, said professor Graham Fieggen, UCT Neuroscience Director.

The facility won't only be treating patients.

It will provide invaluable training to UCT medical students.

11 Animals That Have Changed the History of Neurological Science – Interesting Engineering

Whatever your views on animal testingfor scientific research, they have helped us make some very real breakthroughs in our understanding in fields like neuroscience. By getting to grips with the basic fundamentals of certain aspects of biology using animal analogs for humans, we have been able to harvest various therapeutic solutions and potential cures for some very serious diseases and disorders.

Most of this was only made possible thanks to the sacrifice made by countless animal stand-ins for human beings. If you don't agree with animal testing, perhaps you could volunteer your own living body (and mind) for research purposes in the future?

Yeah, we thought so.

Which animals have had the biggest influence on neurological science?

So, without further ado, here are some of the most important animals in the history of neuroscience. This list is far from exhaustive and is in no particular order.

Rodents, like rats, are one of the most important animals used in a vast swathe of scientific research -- especially in the field of neuroscience. In fact, rats have been used for scientific research for more than 200 years.

After the mid-1980s, when companion animals like cats were phased out, rodents like rats became the go-to animal model for a lot of neuroscientific research.

As instruments became progressively smaller thanks to miniaturization, rats became ideal testbeds for research. Rodents, like rats, also have relatively short lifespans, enabling research into aging and its effects on the nervous system convenient and time-efficient for scientific studies.

Studies on rats have provided insights into neural regeneration, intelligence studies, and many other breakthroughs in science. To date, thirty Noble Prizes in science have been awarded based on research using rats.

While rabbits are primarily used for studying toxicity and safety testing of substances like drugs, chemicals, or medical devices, they have also proved to be vitally important for neuroscientific research.

In fact, one of the earliest scientific breakthroughs came thanks to the work of Louis Pasteur. He is particularly well-renowned for his work on a vaccine for rabies.

This highly contagious infection devastates a host's nervous system and enters the body through being bitten by infected animals or through saliva entering through an open wound.

"When an extract from the spinal column of a rabid dog was injected into healthy animals, symptoms of rabies appeared. By studying the tissues of infected rabbits, Pasteur was able to produce an attenuated form of the virus, which he later used to develop a vaccine against the disease. " - understandinganimalresearch.org.uk.

Much like rats, mice have been a "workhouse" of scientific research, especially in neuroscience. Mice actually form somewhere in the region of 75% of all animal research and, amazingly, have comparable human genes in 98% of their genome.

For the very same reasons as rats are now a very common test animal for research, they are very important to neuroscientific research today.

Mice have very similar reproductive and nervous systems to human beings and suffer from many of the same diseases. From cancer to anxiety, mice are very useful test-animals for finding human treatments for various disorders.

Dogs are not only one of the first domesticated animals, but they have allowed us to make leaps and bounds in our understanding of neuroscience. Apart from research into human-dog bonding, the psychological rehabilitative benefits of dogs with heart-failure patients, research on dogs have helped with some important treatments for major diseases.

One example was a 2012 study into the use of cell transplants for treating spinal cord injury. The trial was conducted on pet dogs with spinal injuries and showed some very interesting results.

Pigs have historically been another important animal in scientific research. With regard to neuroscience, studies on pigs have led to some major breakthroughs in various areas.

One of the most notable was the identification of hypothalamic hormones. Back in the 1950s, research by Roger Guillemain and Andrew von Schally identified that the hypothalamus was responsible for hormonal release from the pituitary gland.

This research was directly transferrable to human beings and allowed researchers and clinicians to make important discoveries into the endocrine system and how it relates to some diseases. They won the Nobel prize for this work in 1977.

Monkeys are another incredibly important group of animals for neuroscientific research. They have a very close similarity to human beings genetically, and physiologically and so are almost perfect analogies for humans.

Some of the most notable neuroscientific breakthroughs from monkey research are significant breakthroughs in our understanding and treatment for Parkinson's disease and tremors. They make near-perfect models for the disorder and have helped develop some essential therapeutic techniques for it.

As an aside, given the current, now confirmed, global pandemic of COVID-19, monkeys, have historically played a major role in identifying and creating vaccines for other coronaviruses like SARS.

Did you know chickens are the closest living relative to certain species of dinosaur? Chickens have also proved to be vitally important for many areas of neuroscientific research. Being vertebrates their developmental process is very similar to our own.

One of the most notable has been the improvement of our understanding of the development of the nervous system.

Primarily how cells migrate and differentiate over time.

Frogs, as it turns out, have helped us understand some fundamental aspects of neuroscience. Studies on frogs helped us, for example, were used to show that nerve impulses affect the heart using a chemical transmission.

This was the first evidence of neurotransmission ever seen.

Studies on them also enabled us to uncover the fact that acetylcholine is responsible for relaying nerve impulses to animals' muscles. Frogs also helped us understand the development of things like the neural plate.

Cats have historically been used for neuroscientific research prior to the mid-1980s. They were ideal test subjects as their size, and their robust nature meant that they could withstand extensive surgery.

They are also large enough to wear or accommodate bulky instrumentation and were also inexpensive animals to breed and keep. But, in the mid-1980s new regulations regarding animal testing substantially increased the economic cost and administrative burden for lab testing on felines.

Public opinion also went against using so-called companion animals in scientific research. After this period, attention shifted more to rodents.

Research on cats has fundamentally improved our understanding of the workings of the nervous system. Most notably, how the visual system needs light to develop as well as the subtle effects of aging on the nervous system.

Ferrets are amazing creatures. They are incredibly smart and, as it turns out, have been instrumental in certain engineering projects including avionics in aircraft.

But, they have also been of great value for expanding our knowledge of neuroscience. Studies on ferrets have allowed us to understand the hypothalamic-pituitary portal system, visual and auditory systems of mammals, including humans.

They have also enabled us to help understand the size of human brains. Ferrets also make great pets, FYI.

And last, but by no means least, is the zebrafish. This incredibly useful little fish is one of the most frequently used model organisms for a lot of genetic and developmental studies.

This is because, primarily, that their embryos or transparent enabling systematic study of them fairly easy. Their entire genetic sequence was also mapped as early as 2011, and their genome has many homologs with that of humans.

With regards to neuroscience, testing on zebrafish has led to some major breakthroughs in our understanding of things like Alzheimer's disease, autism, sleep, heart disease, and some cancers.

New Toolkit May Repair DNA Breaks Linked to Aging and Cancer – Interesting Engineering

Researchers at theUniversities of Sheffield and Oxford have discovered a new toolkit that may help repair DNA breaks that are linked to aging, cancer, and evenmotor neuron disease. The key to this toolkit lies in aprotein called TEX264.

RELATED:WHAT IS DNA COMPUTING, HOW DOES IT WORK, AND WHY IT'S SUCH A BIG DEAL

TEX264 has the capacity toand 'eat' toxic proteins that can stick to DNA and cause it to become damaged. This is key to preventing aging, cancer, and neurological diseases as they are caused by a string of broken DNAs.

"Failure to fix DNA breaks in our genome can impact our ability to enjoy a healthy life at an old age, as well as leave us vulnerable to neurological diseases like Motor Neurone Disease (MND)," saidProfessor Sherif El-Khamisy, Co-Founder and Deputy Director of the Healthy Lifespan Institute at the University of Sheffield and a professor from the Department of Molecular Biology and Biotechnology and the Neuroscience Institute at the University of Sheffield.

"We hope that by understanding how our cells fix DNA breaks, we can help meet some of these challenges, as well as explore new ways of treating cancer in the future."

Now, scientists hope they can use this new protein not only to protect us against aging andneurological diseases but also to find a new way to treat cancer.

"Our finding of TEX264, a protein that forms the specialized machinery to digest toxic proteins from our DNA, significantly changes the current understanding of how cells repair the genome and so protect us from accelerated ageing, cancer and neurodegeneration. I believe this discovery has a great potential for cancer therapy in the future and we are already pursuing our research in this direction," saidProfessor Kristijan Ramadan from the University of Oxford, who co-led the research.

What do you think of this new protein? A promising step toward a better, healthier life or another discovery that likely won't lead anywhere?

Decoding the Future Trajectory of Healthcare with AI – ReadWrite

Artificial Intelligence (AI) is getting increasingly sophisticated day by day in its application, with enhanced efficiency and speed at a lower cost. Every single sector has been reaping benefits from AI in recent times. The Healthcare industry is no exception. Here is decoding the future trajectory of healthcare with AI.

The impact of artificial intelligence in the healthcare industry through machine learning (ML) and natural language processing (NLP) is transforming care delivery. Additionally, patients are expected to gain relatively high access to their health-related information than before through various applications such as smart wearable devices and mobile electronic medical records (EMR).

The personalized healthcare will authorize patients to take the wheel of their well-being, facilitate high-end healthcare, and promote better patient-provider communication to underprivileged areas.

For instance, IBM Watson for Health is helping healthcare organizations to apply cognitive technology to provide a vast amount of power diagnosis and health-related information.

In addition, Googles DeepMind Health is collaborating with researchers, clinicians, and patients in order to solve real-world healthcare problems. Additionally, the company has combined systems neuroscience with machine learning to develop strong general-purpose learning algorithms within neural networks to mimic the human brain.

Companies are working towards developing AI technology to solve several existing challenges, especially within the healthcare space. Strong focus on funding and starting AI healthcare programs played a significant role in Microsoft Corporations decision to launch a 5-year, US$ 40 million program known as AI for Health in January 2019.

The Microsoft program will use artificial intelligence tools to resolve some of the greatest healthcare challenges including global health crises, treatment, and disease diagnosis. Microsoft has also ensured that academia, non-profit, and research organizations have access to this technology, technical experts, and resources to leverage AI for care delivery and research.

In January 2020, these factors influenced Takeda Pharmaceuticals Company and MITs School of Engineering to join hands for three years to drive innovation and application of AI in the healthcare industry and drug development.

AI applications are only centered on three main investment areas: Diagnostics, Engagement, and Digitization. With the rapid advancement in technologies. There are exciting breakthroughs in incorporating AI in medical services.

The most interesting aspect of AI is robots. Robots are not only replacing trained medical staff but also making them more efficient in several areas. Robots help in controlling the cost while potentially providing better care and performing accurate surgery in limited space.

China and the U.S. have started investing in the development of robots to support doctors. In November 2017, a robot in China passed a medical licensing exam using only an AI brain. Also, it was the first-ever semi-automated operating robot that was used to suture blood vessels as fine as 0.03 mm.

In order to prevent coronavirus from spreading, the American doctors are relying on a robot that can measure the patients act and vitals. In addition, robots are also being used for recovery and consulting assistance and transporting units. These robots are showcasing significant potential in revolutionizing medical procedures in the future.

Precision medicine is an emerging approach to disease prevention and treatment. The precision medication approach allows researchers and doctors to predict more accurate treatment and prevention strategies.

The advent of precision medicine technology has allowed healthcare to actively track patients physiology in real-time, take multi-dimensional data, and create predictive algorithms that use collective learnings to calculate individual outcomes.

In recent years, there has been an immense focus on enabling direct-to-consumer genomics. Now, companies are aiming to create patient-centric products within digitization processes and genomics related to ordering complex testing in clinics.

In January 2020, ixLayer, a start-up based in San-Francisco, launched one of its kind precision health testing platforms to enhance the delivery of diagnostic testing and to shorten the complex relationship among physicians, precision health tests, and patients.

Personal health monitoring is a promising example of AI in healthcare. With the emergence of advanced AI and Internet of Medical Things (IoMT), demand for consumer-oriented products such as smart wearables for monitoring well-being is growing significantly.

Owing to the rapid proliferation of smart wearables and mobile apps, enterprises are introducing varied options to monitor personal health.

In October 2019, Gali Health, a health technology company, introduced its Gali AI-powered personal health assistant for people suffering from inflammatory bowel diseases (IBD). It offers health tracking and analytical tools, medically-vetted educational resources, and emotional support to the IBD community.

Similarly, start-ups are also coming forward with innovative devices integrated with state-of-the-art AI technology to contribute to the growing demand for personal health monitoring.

In recent years, AI has been used in numerous ways to support the medical imaging of all kinds. At present, the biggest use for AI is to assist in the analysis of images and perform single narrow recognition tasks.

In the United States, AI is considered highly valuable in enhancing business operations and patients care. It has the greatest impact on patient care by improving the accuracy of clinical outcomes and medical diagnosis.

Strong presence of leading market players in the country is bolstering the demand for medical imaging in hospitals and research centers.

In January 2020, Hitachi Healthcare Americas announced to start a new dedicated R&D center in North America. Medical imaging will leverage the advancements in machine learning and artificial intelligence to bring about next-gen of medical imaging technology.

With a plethora of issues driven by the growing rate of chronic disease and the aging population, the need for new innovative solutions in the healthcare industry is moving on an upswing.

Unleashing AIs complete potential in the healthcare industry is not an easy task. Both healthcare providers and AI developers together will have to tackle all the obstacles on the path towards the integration of new technologies.

Clearing all the hurdles will need a compounding of technological refinement and shifting mindsets. As AI trend become more deep-rooted, it is giving rise to highly ubiquitous discussions. Will AI replace the doctors and medical professionals, especially radiologists and physicians? The answer to this is, it will increase the efficiency of the medical professionals.

Initiatives by IBM Watson and Googles DeepMind will soon unlock the critical answers. However, AI aims to mimic the human brain in healthcare, human judgment, and intuitions that cannot be substituted.

Even though AI is augmenting in existing capabilities of the industry, it is unlikely to fully replace human intervention. AI skilled forces will swap only those who dont want to embrace technology.

Healthcare is a dynamic industry with significant opportunities. However, uncertainty, cost concerns, and complexity are making it an unnerving one.

The best opportunity for healthcare in the near future are hybrid models, where clinicians and physicians will be supported for treatment planning, diagnosis, and identifying risk factors. Also, with an increase in the number of geriatric population and the rise of health-related concerns across the globe, the overall burden of disease management has augmented.

Patients are also expecting better treatment and care. Due to growing innovations in the healthcare industry with respect to improved diagnosis and treatment, AI has gained consideration among the patients and doctors.

In order to develop better medical technology, entrepreneurs, healthcare service providers, investors, policy developers, and patients are coming together.

These factors are set to exhibit a brighter future of AI in the healthcare industry. It is extremely likely that there will be widespread use and massive advancements of AI integrated technology in the next few years. Moreover, healthcare providers are expected to invest in adequate IT infrastructure solutions and data centers to support new technological development.

Healthcare companies should continually integrate new technologies to build strong value and to keep the patients attention.

Healthier and Happier Without Facebook Reduce Usage to Feel Better All Round – SciTechDaily

People who reduce the time they spend on Facebook smoke less, are more active and feel better all round.

Two weeks of 20 minutes less time per day on Facebook: a team of psychologists from Ruhr-Universitt Bochum (RUB) invited 140 test persons to participate in this experiment. Lucky those who took part: afterward they were more physically active, smoked less and were more satisfied. Symptoms of addiction regarding Facebook usage decreased. These effects continued also three months after the end of the experiment. The group headed by Dr. Julia Brailovskaia published their results in the journal Computers in Human Behavior on March 6, 2020.

The research team recruited 286 people for the study who were on Facebook for an average of at least 25 minutes a day. The average usage time per day was a good hour. The researchers subdivided the test persons into two groups: the control group comprised of 146 people used Facebook as usual. The other 140 people reduced their Facebook usage by 20 minutes a day for two weeks, which is about one third of the average usage time.

All participants were tested prior to the study, one week into it, at the end of the two-week experiment, and finally one month and three months later. Using online questionnaires, the research team surveyed the way they used Facebook, their well-being and their lifestyle.

The results showed: participants in the group that had reduced their Facebook usage time used the platform less, both actively and passively. This is significant, because passive use in particular leads to people comparing themselves with others and thus experiencing envy and a reduction in psychological well-being, says Julia Brailovskaia. Participants who reduced their Facebook usage time, moreover, smoked fewer cigarettes than before, were more active physically and showed fewer depressive symptoms than the control group. Their life satisfaction increased. After the two-week period of Facebook detox, these effects, i.e. the improvement of well-being and a healthier lifestyle, lasted until the final checks three months after the experiment, points out Julia Brailovskaia.

According to the researchers this is an indication that simply reducing the amount of time spent on Facebook every day could be enough to prevent addictive behavior, increase well-being and support a healthier lifestyle. Its not necessary to give up the platform altogether, concludes Julia Brailovskaia.

In Maine’s 200 years, man’s impact has altered the animal landscape – Lewiston Sun Journal

A look at the fate of just a few animal species during the 200 years that Maine has been a state tells the larger story of how humans impact wildlife. Whether these animals have vanished, returned, arrived or thrived all have direct or indirect links to human behavior.

Keep in mind, there is also a lot we dont know. Biologists dont have all the data, Noah Perlut, chair of University of New Englands Department of Environmental Studies, pointed out. To take just one example, the breeding bird survey now conducted annually across Maine wasnt even begun until the 1960s.

On the one hand, that is a really rich data set, Perlut said. On the other hand, its nothing compared to how long weve been here. Its not ecologically relevant data.

Here is a glimpse of the fortunes of a few species that roamed the forests, meadows and skies here at the time Maine became a state.

The Departed: Caribou

Since as far back as the 1700, several mammals have been extirpated from Maine or its waters, largely because of over-hunting. They include the gray whale, the eastern cougar (now extinct, although other subspecies of cougars survive in other parts of the country), the gray wolf, the wolverine and the woodland caribou.

In the 1800s, caribou were a source of food that was readily available, said Mark McCollough, the endangered species biologist in Maine with the U.S. Fish and Wildlife Service. So much so, in fact, that they sustained the early settlers in northern Maine. But the last recorded caribou in Maine was shot on Mt. Katahdins Tablelands in 1908, he said.

More than 50 years later, in 1963, the state attempted to reintroduce them. Biologists brought 20 caribou from nearby Newfoundland to Baxter State Park. The project failed, though biologists at the time were not certain why, McCollough said. Portland businessmen funded a similar effort in 1986. Twenty caribou from Newfoundland were taken to Orono to breed. Later, 30 were released in Baxter, this time with radio collars affixed to their necks so scientists could track and study them more closely. Once again, not a single caribou survived. All fell prey to hungry bears or to brainworm, a parasite carried by, but not affecting, white-tailed deer.

It illustrated how difficult it is to try to right some of the wrongs that happened 100 or 200 years ago, McCollough said. If the environment has changed, there are factors that we may not even be aware of, like diseases that were not present 100 years ago.

The Survivor: White-Tailed Deer

Three commonly seen mammals have persisted in Maine at least since the early settlers arrived: moose, bear and white-tailed deer. But only the last has reached extraordinary numbers. In 2019, thestatewide population was estimated between 230,000 and 250,000, according to the Maine Department of Inland Fisheries and Wildlife.

They live in cities and in deep woods, McCollough said. They live alongside us and benefit from the changes we make to the environment, whether carving out backyards or forestry projects. They like a fragmented forest.

At the turn of the 1800s, when northern Maine was first settled, few deer lived there, McCollough said. Their numbers grew in the next 100 years with the advent of log drives and the arrival of forestry. Such timber practices created new tree growth, providing the deer with the low-lying branches they like to eat. Coupled with urbanization in southern Maine, which fragmented the forests, deer numbers exploded.

Whatever happens with climate change, I have no doubt that deer will still be here 200 years from now, McCollough said.

The Returnee: Peregrine Falcon

Some good news: some of the species that vanished from Maine over the last 200 years have since returned. Typically, humans played a role both in their disappearance and their revival. As hunting practices ended or were curtailed, and as pollutants and insecticides were cleaned up or banned, a few species that roamed Maine historically are repopulating the state.

The fastest bird in the world the peregrine falcon was once extirpated from Maine. The peregrine, which can fly more than 200 mph, nested in the eastern United States until the early 1960s when widespread use of the insecticide DDT pushed the birds to the brink of extinction. The federal government listed them as endangered in 1970. Although DDT was banned in 1972, the raptor is still considered endangered in Maine. Through reintroduction efforts, however, their numbers here have grown.

A total of 153 young peregrines were reintroduced in Maine between 1984 and 1997. Since 2009, Maine has been home to at least 25 nesting pairs, according to the Maine Department of Inland Fisheries and Wildlife. Efforts by the state to create nesting platforms for the birds are ongoing.

In a lot of regions of the Northeast, peregrine falcons only nested on cliffs, Perlut said. Now they are nesting on bridges and quarries and buildings. That is adding more pairs than maybe were here historically.

The Newcomer: Turkey Vulture

Probably no animal better illustrates the resiliency of a newcomer in Maine than the coyote, which migrated across the country from the western United States in the 1940s. If it can survive in New York Citys Central Park, why not Maine? And it does.

A number of other non-native species have successfully moved here, too, including two species of vultures: the turkey vulture and the black vulture. The first documented breeding pair of turkey vultures arrived in 1970; they are now widespread across the state. In the past few years, there have been reports that black vultures are breeding here, too, Perlut said.

What drew them north? One theory credits urbanization, he said. Others believe birds follow highways, for the opportunity for road kill.

[OPINION] The Pope and single-use plastics – Rappler

What is more urgent and effective: go big or start small?

This is one of the fundamental questions I encounter when addressing the climate crisis. Some would argue that given the need to drastically reduce greenhouse gas (GHG) emissions within the next decade, the focus should be on pressuring authorities to implement large-scale solutions. Governments must enact policies for phasing out fossil fuels, especially coal, while corporations need to either stop funding environmentally-destructive projects or implement a just transition towards renewable energy development.

While these measures are obviously effective in mitigating and adapting to climate change, the value of the small-scale actions can never be discredited. These actions help create a precautionary culture wherein caring for the planet becomes a habit instead of an incentive, an initiative rather than a reaction. An educated, enabled, and empowered citizenry is also vital for exerting pressure on governments and corporations to instigate shifts in political and socioeconomic models to deal with the climate crisis.

The importance of behavioral change to stop climate change is evident, whether you look at it through a scientific or religious lens.

The religious lens

Pope Franciss encyclical "Laudato Si" is known as a landmark document of the Roman Catholic Church for directly addressing the climate crisis and environmental degradation. Yet at its core, it points to one undeniable fact: that human behavior is at the root of the ecological crisis, and therefore at the heart of solving it.

The Laudato Si calls for the creation of an ecological citizenship, where people are adequately motivated to respond to the call on caring for our common home. This would be brought about by environmental education with a renewed focus on ecological ethics.

Given the challenges of today, education centered on scientific information, raising awareness, and avoiding environmental risks is no longer enough. It also needs a focus on critiquing and shattering the myths we consider as norms of the current modern life, from infinite growth to consumerism. It ultimately points for us to conduct ourselves in a way that is indicative of a lifestyle in harmony within ourselves and with others on Earth.

Activities such as avoiding the use of single-use plastics, minimizing wasteful consumption of food, water, and electricity, using public transportation, and tree-planting and growing have positive impacts in our struggle for protecting our planet. Doing these actions do not just benefit our environment; they also provide personal co-benefits in aspects such as financial savings and better health. (READ: Philippine survey shows 'shocking' plastic waste)

While these acts are done on an individual level, that does not mean they should be misconstrued as modes exclusively for self-improvement. A dilemma with the complexity of the climate crisis requires a societal approach to properly address them. Given their potential positive impacts on the individual and communal levels, such activities are likely to spread and be adopted by different communities.

As Pope Francis states, when done for the right reasons, each of these solutions can be considered as an act of love that reflects our societal responsibility for others and expresses our individual dignity.

The scientific lens

Several scientific reports have also proven the effectiveness of small-scale solutions for mitigating and adapting to the impacts of climate change. A 2018 study by the Center for Behavior and the Environment showed that almost two-thirds of global GHG emissions are associated with both direct and indirect means of human consumption.

It is noteworthy that almost every item we consume is made using resources such as fossil fuels. Therefore, if we start minimizing unnecessary consumption and actively look for alternatives, we are pressuring manufacturers to switch to more environment-friendly production and distribution systems, which in turn reduces consumption of pollutive fossil fuels and other resources. (READ: Single-use plastics, still the environment's number 1 enemy)

Furthermore, implementing small-scale behavioral solutions can reduce GHG emissions by as much as 37% from 2020 to 2050. These solutions involve modifications to activities involving food, agriculture and land management, transportation, and energy and materials.

This is supported by a report by Project Drawdown, a nonprofit organization dedicated to urgently reducing global GHG emissions. It claims that while the solutions to the climate crisis already exist, some of them receive relatively little attention compared to large-scale solutions such as developing more renewable energy resources, especially wind and solar.

This report identified the following as seven of the 10 most effective individual solutions: reduced food waste, health and education, plant-rich diets, refrigerant management, tropical forest restoration (including tree-planting), alternative refrigerants, and improved clean cookstoves. (READ: Sachet away: What's lacking in our plastic laws?)

The expression great things from small beginnings is almost a clich nowadays, but it still applies when it comes to climate and environment action. Everyone needs to be involved in preventing further climate change and environmental degradation. And despite what some people might tell you, accessible and affordable solutions do exist. An act of love could truly go a long way. Rappler.com

Because of coronavirus were doing things differently. How long will that last? – San Francisco Chronicle

It isnt easy to change habits, as those who have tried to go a day without touching their face have found, but the coronavirus outbreak is threatening to modify human behavior, culture, business and yes habits in ways that could permanently alter our way of life.

The COVID-19 pandemic has already disrupted American society, causing the stock market to plummet, and workplaces, theaters and sports leagues to close down as people across the country stockpile food and hole up at home.

Locally, ridership on BART and other mass transit has declined, and movie theaters, bars and restaurants are virtually empty. Handshakes, hugs, high-fives and kisses on the cheek have become almost taboo. Even the untidy among us have become germophobes, incessantly washing our hands and wiping down surfaces.

The impacts of the growing pandemic are far reaching, but the biggest changes are in the business realm, where experts say increased teleconferencing, automation and e-commerce could become standard even after the virus threat is gone.

Companies will put in infrastructure to enable remote working, to make sure people can operate seamlessly and communicate well regardless of where they are on the planet, said Darren Murph, head of remote for GitLab, a software company whose 1,150-plus employees all work remotely.

He thinks the coronavirus will make telecommuting the norm for people who now only occasionally work from home when they are waiting for a repair person or attending a childs school event.

This is like a get-out-of-jail-free card that every major city in the world never saw coming but will be so grateful for, Murph said. Were already way oversubscribed with people on public transit and in cars on the road. This will reduce strain on the infrastructure without spending any money.

The changes will be necessary, given that it could take 12 months or longer before a vaccine is developed. And restrictions could get more draconian as the number of infections grow, including mandatory home quarantines.

It is unlikely that many cities and regions could be isolated, like has happened in China and New Rochelle, N.Y. But the fast-spreading disease has forced Italy into a lockdown and the United States is, by all accounts, still in the beginning stages of infection.

Experts say the disease is likely to have long-term implications on how much people fly or take mass transit and even whether they greet people with a handshake or the newly fashionable elbow bump.

But major changes in our personal habits are unlikely, said Russell Poldrack, a neuroscientist at Stanford University and an expert on habit-forming behavior. Once the threat is over, he said, people will probably go back to touching their faces, shaking hands, hugging, kissing and failing to wash their hands frequently.

Whether (new behaviors) become permanent depends on how long this lasts and how bad it gets, Poldrack said. Take handshakes. They are so deeply ingrained in our fabric, but it could well be that the virus drives people to worry enough about disease transmission that they change to some other greeting.

New technologies, if not new habits, are more likely to catch on and become permanent as the virus spreads, said Ken Goldberg, a professor of engineering and robotics at UC Berkeley.

I think it will accelerate that tendency to order things online, especially things like food and groceries, Goldberg said. That, in turn, will increase a demand for robots to fulfill these orders.

An example of a technology that could boom during the crisis, he said, are robots that collect items in warehouses and package them for online shoppers, an industry that is now booming in China as a result of the new coronavirus.

Fear of infection among health care workers could also drive innovations in telemedicine, including remote-control robots that can help doctors examine patients without having to be there in person, he said. An Israeli startup, TytoCare, has developed such a system, allowing doctors to guide patients from afar as they perform medical tests on themselves using a handheld exam kit.

Similarly, the reluctance of people to go to large meetings and conferences will likely increase demand for tele-robots, with video screens and microphones, that could attend a conference in a persons place, allowing virtual delegates to network while lounging at home in their pajamas. Such robots are available now, but they are rare.

I think its a game changer in that (telecommuting) may be our new normal, said Bernard Coleman, head of employee engagement at Gusto, a payroll, benefits and human resources platform for small businesses.

One offshoot could be rethinking work hours.

Do the hours of 9 to 5 even make sense anymore? Coleman said. What if people are more productive from 11 a.m. to 7 p.m.?

A reduction of in-person conferences could force many professional societies to develop new business models, since the income from annual meetings helps fund their advocacy, training, research and other activities. But replacing large annual meetings with virtual conferences isnt all bad, said Dr. Dan Diekema, director of the infectious disease division at the University of Iowa.

There has been pressure building on this from an environmental standpoint because of the emissions produced by travel, Diekema said in an email. Now perhaps a tipping point will be reached.

Another example of a potentially permanent change is happening at UC Berkeley, Stanford and many other major universities around the country, where classes are being taught exclusively online as a result of the COVID-19 scare.

The technology obviously is never going to be as good as being there, but as people get used to going to classes, religious services and other places remotely, it could catch on, Goldberg said. Maybe we will adapt and in 20 years, it will be normal for people to have remote meetings.

A range of domino effects could occur if working from home becomes more commonplace. Some would benefit society: less traffic and thus fewer emissions. But the flip side would be fewer people on public transit, hurting agencies that depend on fare revenues. There would also be fewer patrons at restaurants that depend on workers for lunchtime business, and fewer customers in stores.

Businesses also might need less office space if there is a permanent increase in telecommuting, causing building vacancies and reducing rents. That could actually help San Francisco, which has a serious office space shortage, said Jay Cheng, public policy director of the San Francisco Chamber of Commerce.

Paid sick leave could be a long-lasting legacy of the coronavirus pandemic. Currently, the U.S. has no mandate for employers to offer paid sick leave, or paid family medical leave, which typically is longer. As a result, one quarter of workers about 30 million people who lack the benefit must decide whether to forgo a paycheck or risk going to work and transmitting or contracting disease.

The crisis has ignited debate on Capitol Hill and elsewhere, with proponents highlighting studies that mandatory paid leave decreases flu rates. Historically, Democrats have pushed for paid sick leave, while Republicans have opposed it as hurting businesses.

Now, folks on both sides of the aisle are talking about the need to do something, said Ruth Martin, chief workplace justice officer for MomsRising, a nationwide advocacy group pushing the Healthy Families Act, which would require businesses with at least 15 employees to provide seven days a year of paid sick leave.

In fact, the emergency relief plan that Congress passed early Saturday with broad bipartisan support includes two weeks of paid sick leave and up to three months of paid family and medical leave, as well as expanded unemployment insurance. While they are temporary and only for people affected by the coronavirus, those benefits lay the groundwork for similar future legislative action.

David Levine, a professor at the Haas School of Business at UC Berkeley, said change usually happens slowly, and even in this situation probably needs a push.

This (disease) is forcing many places and schools to try something new, and once the fixed cost of learning new software, new routines and changing the norm is over, some of them are going to say, Hey, this is a better way, Levine said. But the way to make necessary changes systematic is not to rely on individuals. To the extent that organizations institute safe routines there can be lasting change. When you walk into a doctors office, they should ask you to wash your hands.

Robots that admit mistakes foster better conversation in humans – Yale News

Three people and a robot form a team playing a game. The robot makes a mistake, costing the team a round. Like any good teammate, it acknowledges the error.

Sorry, guys, I made the mistake this round, it says. I know it may be hard to believe, but robots make mistakes too.

This scenario occurred multiple times during a Yale-led study of robots effects on human-to-human interactions.

The study, which published on March 9 in the Proceedings of the National Academy of Sciences, showed that the humans on teams that included a robot expressing vulnerability communicated more with each other and later reported having a more positive group experience than people teamed with silent robots or with robots that made neutral statements, like reciting the games score.

We know that robots can influence the behavior of humans they interact with directly, but how robots affect the way humans engage with each other is less well understood, said Margaret L. Traeger, a Ph.D. candidate in sociology at the Yale Institute for Network Science (YINS) and the studys lead author. Our study shows that robots can affect human-to-human interactions.

Because social robots are becoming increasingly prevalent in human society, she said, people are encountering them in stores, hospitals and other everyday places. This makes understanding how they shape human behavior important.

In this case, Traeger said, we show that robots can help people communicate more effectively as a team.

As we create hybrid social systems of humans and machines, we need to evaluate how to program the robotic agents so that they do not corrode how we treat each other.

The researchers conducted an experiment in which 153 people were divided into 51 groups composed of three humans and a robot. Each group played a tablet-based game in which members worked together to build the most efficient railroad routes over 30 rounds. Groups were assigned to one of three conditions characterized by different types of robot behavior. At the end of each round, robots either remained silent, uttered a neutral, task-related statement (such as the score or number of rounds completed), or expressed vulnerability through a joke, personal story, or by acknowledging a mistake; all of the robots occasionally lost a round.

People teamed with robots that made vulnerable statements spent about twice as much time talking to each other during the game, and they reported enjoying the experience more compared to people in the other two kinds of groups, the study found.

Conversation among the humans increased more during the game when robots made vulnerable statements than when they made neutral statements. Conversation among the humans was more evenly distributed when the robot was vulnerable instead of silent.

The experiment also showed more equal verbal participation among team members in groups with the vulnerable and neutral robots than among members in groups with silent robots, suggesting that the presence of a speaking robot encourages people to talk to each other in a more even-handed way.

We are interested in how society will change as we add forms of artificial intelligence to our midst, said Nicholas A. Christakis, Sterling Professor of Social and Natural Science. As we create hybrid social systems of humans and machines, we need to evaluate how to program the robotic agents so that they do not corrode how we treat each other.

Understanding the social influence of robots in human spaces is important even when the robots do not serve an intentionally social function, said Sarah Strohkorb Sebo, a Ph.D. candidate in the Department of Computer Science and a co-author of the study.

Imagine a robot in a factory whose task is to distribute parts to workers on an assembly line, she said. If it hands all the pieces to one person, it can create an awkward social environment in which the other workers question whether the robot believes theyre inferior at the task. Our findings can inform the design of robots that promote social engagement, balanced participation, and positive experiences for people working in teams.

We’ve Been Transforming the Earth for at Least 10000 Years – The Good Men Project

By KEITH RANDALL-TEXAS A&M

The study synthesizes data from 255 archaeologists to provide the first global survey of the Earths transformation through human land use over the past 10,000 years. The findings challenge the commonly held view that large-scale, human-caused environmental change is a relatively recent phenomenon. It also shows how the overall impact of human behavior has been growing exponentially since the end of the last Ice Age.

Our team synthesized archaeological data provided by experts from around the world to establish a timeline for when people in different parts of the world began to intensify land use in different ways, says Heather Thakar, assistant professor in the anthropology department at Texas A&M University.

The ArchaeoGLOBE project analyzed land use from roughly 10,000 years ago, the time of hunters and gatherers, to the year 1850, after the Industrial Revolution.

I BELIEVE THAT WE WILL ALSO FIND A WAY TO ENSURE THAT OUR HOME REMAINS HABITABLE FOR OUR SPECIES.

The new study adds an archaeological perspective to existing models of historical land use. Based on researchers expertise of land use on six continents, the crowdsourced map shows that agriculturean extraction of environmental resources that leaves a complex mark on the landscapebegan earlier, and in more parts of the world, than more recent studies have reported.

There are archaeologists working all over the world, but they aggregate data differently, and it can be difficult to find larger patterns, says coauthor Ben Marwick, an associate professor of anthropology at the University of Washington. By asking archaeologists a series of questions rather than combining datasets, weve created a brilliant workaroundessentially, what were people doing, and how much, in different parts of the world?

The researchers looked at how human global land use has transformed the surface of the Earth, especially in the last 10,000 years. They divided Earth into 146 regions and used 10 time periods, from 10,000 years ago to 1850.

They found that about 42% of the regions examined had some form of agriculture by about 6,000 years ago, and that the beginnings of agriculture occurred earlier than previously believed.

The researchers conclude that foragers, farmers, and herders had transformed the planet by 3,000 years agomuch earlier than the timeframe derived from the most common land-use reconstructions used by earth scientists. In some regions, the survey showed effects of intensive land-use more than 1,000 earlier than previous estimates.

The industrial revolution and large-scale agriculture often spring to mind when people think about human impact on the environment, but these findings show that humans have been transforming the landscape going back at least 10,000 years, says coauthor Jessica Thompson, an anthropologist at Yale University. The line that separates the pristine natural world from one transformed by people is blurrier and goes further back in time than what is commonly believed.

The map is covered in dark green at the beginning of the time span (10,000 years ago) but the green gets lighter across the map as foraging becomes rarer

The survey found that foraging, which includes hunting, gathering, and fishing, was commonplace 10,000 years ago in 120, or 82%, of the 145 regions. However, foragers were not passive occupants; they also drastically changed landscapes, such as through extensive burning, to improve conditions for hunting and gathering, according to the study.

WE ARE AT A CRITICAL TURNING POINT.

Certainly foragers had significant impacts on the plant and animal communities where they lived, Thompson says. They manipulated the landscape to enhance their chances of survival. They might burn land to increase its productivity or influence how vegetation grows to attract animals to hunt.

We need to start thinking more seriously about that activity when we consider what constitutes an environment or landscape transformed by people. And that requires archaeologists to be a part of the conversation about modern-day human impacts.

Think of it this way: when humans began to intensify land use in different ways, often times associated with increased food production, they also began to alter the local landscape and ecology in significant and lasting ways, such as human driven extinctions and deforestation, Thakar says.

We have established that intensive human impacts on local environments begin much earlier than many researchers had previously assumed. This work provides important historical context for our rapidly accelerating impacts on the Earth.

The teams research also examines the origins of the Anthropocene, which is a term used to mark how people shaped the world and continue to shape it through their actions. The word combines anthropo, meaning human, and cene, meaning an epoch of geologic time.

I would say the Anthropocene Era is already widely accepted by the scientific community, Thakar says. The idea that human activity has become a dominant influence on the global environment during recorded history is well-established. What is debated, across disciplines, is not whether the Anthropocene exists, but the point at which our actions as a species became a climatic-driving force on par with that of major geologic processes.

Thakar notes that the project contributes a global assessment of how far we can push scientific evidence of human-induced landscape transformations.

The Anthropocene includes major milestones in human history, among them the invention of the wheel 3,500 years ago; the printing revolution that began in 1439; the scientific revolution from 1543 to 1687; the invention of the steam engine in 1712; the worlds population reaching 1 billion in 1804; the first electric motor in 1822; the first modern oil well built in 1859; World War I and World War II; the atomic age in 1945; the Great Accleration of knowledge that began in 1950 and continued for the next 60 years with unprecedented discoveries; and to 2011 when the world population hit 7 billion.

It raises the question: what do the next thousand years hold for humankind?

I think that we need to be concerned, not just about some distant future (1000 years), but the very near future (10-100 years) which offers our greatest opportunity to consciously, critically, and deliberately influence the Earths climate, Thakar says. Our past does help predict our future, and our past documents humanitys incredible capacity for innovation and collective action. Once we accept the truth of our role as climate-drivers, I believe that we will also find a way to ensure that our home remains habitable for our species.

She adds that archaeological data demonstrates humans ability to adapt to changing conditions, giving hope that we can find ways to adapt to global climatic changes in our future.

But, what we face today is unprecedented in both pace and scope, Thakar says. We are at a critical turning point. In order to land safely in the future, we must change outdated and destructive habits and replace them with new, future-oriented solutions.
