A unique brain signal may be the key to human intelligence – Big Think

Though progress is being made, our brains remain organs of many mysteries. Among these are the exact workings of neurons, with some 86 billion of them in the human brain. Neurons are interconnected in complicated, labyrinthine networks across which they exchange information in the form of electrical signals. We know that signals exit an individual neuron through a fiber called an axon, and also that signals are received by each neuron through input fibers called dendrites.

Understanding the electrical capabilities of dendrites in particular which, after all, may be receiving signals from countless other neurons at any given moment is fundamental to deciphering neurons' communication. It may surprise you to learn, though, that much of everything we assume about human neurons is based on observations made of rodent dendrites there's just not a lot of fresh, still-functional human brain tissue available for thorough examination.

For a new study published January 3 in the journal Science, however, scientists got a rare chance to explore some neurons from the outer layer of human brains, and they discovered startling dendrite behaviors that may be unique to humans, and may even help explain how our billions of neurons process the massive amount of information they exchange.

Electrical signals weaken with distance, and that poses a riddle to those seeking to understand the human brain: Human dendrites are known to be about twice as long as rodent dendrites, which means that a signal traversing a human dendrite could be much weaker arriving at its destination than one traveling a rodent's much shorter dendrite. Says paper co-author biologist Matthew Larkum of Humboldt University in Berlin speaking to LiveScience, "If there was no change in the electrical properties between rodents and people, then that would mean that, in the humans, the same synaptic inputs would be quite a bit less powerful." Chalk up another strike against the value of animal-based human research. The only way this would not be true is if the signals being exchanged in our brains are not the same as those in a rodent. This is exactly what the study's authors found.

The researchers worked with brain tissue sliced for therapeutic reasons from the brains of tumor and epilepsy patients. Neurons were resected from the disproportionately thick layers 2 and 3 of the cerebral cortex, a feature special to humans. In these layers reside incredibly dense neuronal networks.

Without blood-borne oxygen, though, such cells only last only for about two days, so Larkum's lab had no choice but to work around the clock during that period to get the most information from the samples. "You get the tissue very infrequently, so you've just got to work with what's in front of you," says Larkum. The team made holes in dendrites into which they could insert glass pipettes. Through these, they sent ions to stimulate the dendrites, allowing the scientists to observe their electrical behavior.

In rodents, two type of electrical spikes have been observed in dendrites: a short, one-millisecond spike with the introduction of sodium, and spikes that last 50- to 100-times longer in response to calcium.

In the human dendrites, one type of behavior was observed: super-short spikes occurring in rapid succession, one after the other. This suggests to the researchers that human neurons are "distinctly more excitable " than rodent neurons, allowing them to successfully traverse our longer dendrites.

In addition, the human neuronal spikes though they behaved somewhat like rodent spikes prompted by the introduction of sodium were found to be generated by calcium, essentially the opposite of rodents.

The study also reports a second major finding. Looking to better understand how the brain utilizes these spikes, the team programmed computer models based on their findings. (The brains slices they'd examined could not, of course, be put back together and switched on somehow.)

The scientists constructed virtual neuronal networks, each of whose neurons could could be stimulated at thousands of points along its dendrites, to see how each handled so many input signals. Previous, non-human, research has suggested that neurons add these inputs together, holding onto them until the number of excitatory input signals exceeds the number of inhibitory signals, at which point the neuron fires the sum of them from its axon out into the network.

However, this isn't what Larkum's team observed in their model. Neurons' output was inverse to their inputs: The more excitatory signals they received, the less likely they were to fire off. Each had a seeming "sweet spot" when it came to input strength.

What the researchers believe is going on is that dendrites and neurons may be smarter than previously suspected, processing input information as it arrives. Mayank Mehta of UC Los Angeles, who's not involved in the research, tells LiveScience, "It doesn't look that the cell is just adding things up it's also throwing things away." This could mean each neuron is assessing the value of each signal to the network and discarding "noise." It may also be that different neurons are optimized for different signals and thus tasks.

Much in the way that octopuses distribute decision-making across a decentralized nervous system, the implication of the new research is that, at least in humans, it's not just the neuronal network that's smart, it's all of the individual neurons it contains. This would constitute exactly the kind of computational super-charging one would hope to find somewhere in the amazing human brain.

Rhode Island Hospital Tests mHealth Wearable to Track Eating Habits – mHealthIntelligence.com

January 09, 2020 -A Rhode Island hospital is launching a pilot program to determine whether an mHealth wearable can help users lose weight.

Researchers the The Miriam Hospital, part of the Lifespan Health System, will be using an mHealth device called the Automatic Ingestion Monitor. Developed at the University of Alabama, the AIM attaches to a users eyeglasses and monitors eating habits, including what kinds of foods are eaten, how much, how often and how fast.

Ultimately, we hope that it will be a tool for patients to use to improve their eating habits, says Graham Thomas, PhD, a behavioral scientist at the Providence-based hospitals Weight Control and Diabetes Research Center and an associate professor of psychology and human behavior at Brown University. The information that the AIM collects could be shared with care providers to help them evaluate their progress towards goals for diet and eating, and identify problematic eating behaviors.

Funded by a $2.5 million grant from the National Institutes of Health, the clinical trial aims to test whether telemedicine technology can help care providers remotely monitor the eating habits of patients dealing with weight issues. Armed with that data, providers could conceivably improve care management for a wide range of chronic issues, including obesity, diabetes, heart disease, high blood pressure and even behavioral health concerns.

Alongside Thomas, the study includes researchers at the University of Alabama, Boston University and the University of Colorado.

The key to this particular technology is to learn individual eating behaviors and then attempt to provide personalized feedback to modify those behaviors, said Edward Sazarov, a professor of electrical and computer engineering at the University of Alabama who created the device and is a co-principal investigator with Thomas, in a press release.

The way you eat is as important as what you eat. We are also looking at the rates of ingestion, he added. We want to slow down and be more mindful about our eating. Every person is different in when they eat, what they eat, how much they eat and how long they eat. We use machine learning to create a model of these individual eating patterns. After we learn the individual eating patterns, we see how it can be manipulated by suggesting small changes to reduce the total amount of energy consumed.

The digital health platform captures data from the device and stores it in the users smartphone, where it can be retrieved and viewed by both the user and care providers. The platform can also be programmed to deliver messages to the user about eating behaviors.

Current programs aimed at improving diet and eating behavior largely require the patient to maintain total vigilance of their eating, often requiring them to accurately track how much they are eating, says Thomas, who is recruiting roughly half of the patients for the study. This technology has the potential to relieve much of that burden and provide the patient with more accurate information than they could collect themselves. Having accurate information on ones behavior is critical for making healthy changes to those behaviors.

A key challenge in mHealth studies that use wearables centers on whether the technology is unobtrusive and fits into the users everyday lifestyle. Thomas said this study will focus on the effects of technology on behaviors, while a long-term goal would be to continue making the technology smaller and less noticeable to improve user engagement.

7 Skills To Help You Close More Business At Your Hotel – Hospitality Net

Master group sales & eventsFor hoteliers selling to groups, understanding the ins and outs of the human mind can be of great benefit. It's not about manipulation; it's about understanding human behavior in a business that is, at its core, a people business.

The objective is to dial into your clients' wants and needs, and then delivering. Think of it as highly attuned Persona Matching: you know your target clients so well that you can predict behavior, influence decisions, cut through the noise and address underlying needs better than the competition. So how can you leverage the psychology of selling to become a true group sales pro? These are the seven skills that will help you close more groups and events at your hotel.

1. Be more observant

2. Ask more questions

With proper deduction skills, you'll avoid the trap of making false assumptions about a particular group or event. Sure, there's a lot to learn from the size of a group, type of the group, and who is planning the event. Yet there's also the risk of making assumptions that lead you astray. When you're asking enough questions, you eliminate assumptions and illuminate the unmet needs.

Questions also give you a path to overcoming objections. You don't just have to guess your prospects' concernsyou can ask them directly! Whether it's in your initial call or via a follow-up email, just ask so you can tackle those concerns head-on while also learning more about your prospect. Then, you can say this to them:

"You told me you were concerned about price, so I crafted three custom packages to offer you the most variety. I think you'll find one that meets your needs at a great price."

When you answer the internal conversations prospects are already having, you appear proactive and trustworthy two qualities that are especially desirable for those organizing events.

3. Listen to the answers

By staying attuned to your clients, you'll be able to connect the dots between what your property offers, what the client needs, and what you can do to make the client's event a success. To be a better listener, do three things:

4. Read body language

5. Use social proof

So, give them the nudge they need to say yes by convincing them that your hotel is the ideal host for their event. Whether at the initial RFP stage, the property walk-around, or at the final contract stage, success lies in emphasizing how your hotel meets their needs. You should provide all the information they need to give them the confidence to say yes.

This confidence is built along the prospect's journey, with each touchpoint an opportunity to position your hotel favorably in the prospect's evaluation. The key is to back up all claims with proof points, so that you can provide social proof that your hotel is as good as you say it is.

For each specific event type (wedding, off-site, etc), update your website, marketing materials, and proposal templates to feature satisfied customers. Put their photos alongside descriptive testimonials that highlight how exceptional their experience was.

Customize your proposal to include only the most relevant testimonials, choosing event types, personalities, and brands that resonate with the prospect's own needs and situation. The right social proof, coupled with compelling copy that highlights your property's bonafides, is the path to conversion.

6. Know your prospect

Remember that people don't always say what they mean or know exactly what they want. When a potential client says one thing, and exhibits behavior that suggest otherwise, it's wise to listen to that intuition. That doesn't mean ignore what they say; it means providing an additional option that may align more with what they actually want but can't verbalize.

Consider a common event type for group sales at hotels: Weddings. You should have a very different approach between building out of a proposal for a couple versus an experienced wedding planner. The couple is likely experiencing wedding planning for the first time and is personally invested in every detail. For them, there's a lot of fear and uncertainty as they plan such a major milestone event. Whereas the event planner has plenty of experience and is likely going to be much more practical and focused on delivering for the clients.

In other words, the planner may focus more on the logical benefits while a couple focuses more on the emotional benefits. It won't always be the case, but the example illustrates the importance of tailoring your approach to your audience. Your hotel's sales process should accommodate these differences and use your knowledge of the audience to strengthen your offering.

7. Tell stories that connect emotion and need

Maya Angelou once said, "People will forget what you said, people will forget what you did but people will never forget how you made them feel." When you focus on emotion or how people feel you're able to tap into a deep well of human connection.

This is especially relevant for group sales, which often involve emotional decisions: the couple getting married, the corporation celebrating a milestone, the family coming together for a reunion. Each of these event types has needs and emotion associated with it; a group sales pro leans right into those to deliver a winning proposal.

Stories are the most effective path to tie the emotion to the need. Stories should show how the prospect feels when fulfilling their needs: the couple that gets a knockout wedding under budget, the corporate events planner that wows executives with an over-the-top event, the cousin that brings together 5 generations for the first (and likely) only time. Tell that story with the prospect as the main character, and you build the scaffolding to close more deals.

The Next Climate Tech Breakthrough May Have Already Happened, We Just Didn’t Notice – State of the Planet

by Isabelle Seckler|January 10, 2020

Photo: Pixabay

The president of the UN General Assembly says we have only 11 years to prevent irreversible damage to our planet from climate change. Thats a short deadline in which to prevent an existential crisis. The global community is desperate for solutions that prevent further environmental damage and help us adapt to life in a new climate.

To stay within the targeted limit of 1.5 degrees Celsius of warming, scientists insist that we need to reduce the carbon thats already in the atmosphere, in addition to dropping new emissions to net-zero. The goal is to implement carbon dioxide removal strategies that capture carbon from the air and safely store it.

Existing CO2 removal technologies usually mimic natural biogeochemical processes that sequester carbon, or amplify the carbon-capturing qualities of the ocean, forests and sedimentary rocks. One method would fertilize phytoplankton in the ocean to increase the photosynthetic uptake of carbon. Another relies on crushing up carbon-absorbing rocks to increase their surface area, storage potential, and the rate of carbon removal.

Now, more than ever, there is a need for creative solutions, and these examples show that the next breakthroughs in sustainable development wont come from Silicon Valley or scientific labs, but from Mother Nature. We havent paid enough attention to the natural world to recognize that it teems with potential solutions to our problems, hiding in plain sight. We can improve the very infrastructure of our built environment if we mimic certain biochemical and geological processes readily found in the natural environment.

Mother Nature is a master innovator. Her breakthroughs are not revolutionary, but evolutionary. Natural selection is the longest-running research and development project it has lasted 3.8 billion years and counting, to be exact. The traits that survive are the ones that are best adapted to thrive in their specific environment, from sticky gecko feet to water-collecting lotus petals.

The biological world that exists today is efficient, effective and made of the stuff of science fiction: self-regeneration, water resistance, antibacterial materials, incredibly weird methods of movement. Its a world of dynamic innovation that often goes unacknowledged.

Learning about the natural world is one thing. Learning from the natural world thats the switch. Thats the profound switch. Janine Benyus

There is a growing trend of scientists looking toward nature through a new perspective: biomimicry. Essentially, its design innovation that models the natural world. The term was popularized in the 1990s by Janine Benyus, co-founder of the Biomimicry Institute.

The examples are as fascinating as they are absurd. The bullet trains in Japan reach nearly 200 mph thanks to the Kingfisher birds aerodynamic beak. Wind turbines are 20 percent more energy efficient when shaped like humpback whale fins, and termite mounds show architects how to improve building air conditioning systems. Industry giants like Seventh Generation are looking to beetles that spray poison to remake aerosol packaging. Swimsuits constructed like shark skin reduce drag so effectively that they were banned at the Olympics. Medical spaces are even applying the antimicrobial properties of shark skin to create sterile surfaces without producing antibacterial resistance.

New technologies that owe their designs to biological models are highly lucrative. Its estimated that roughly $1.6 trillion of global GDP will come from products and services based on biological design by 2030.

The true value of biomimicry is priceless. Especially if it can be applied to develop carbon-capture technology. One company, Calera, believes that the way corals absorb carbon dioxide into their limestone skeletons can teach us how to capture carbon dioxide from the air and create cement. Imagine living in sustainable cities literally built from repurposed air pollution.

In a recent podcast, biomimicry expert Danya Baumeister explains how biomimicry can help us bolster our climate resiliency. In her eyes, nature is a shining model for how we could make materials that arent harmful and dont require lots of energy how we could build communities and cities in a way that actually gives back to the local ecosystem as opposed to just drains the local ecosystem.

A whole new market niche for sustainable, nature-based designs has opened up in the last few years. Databases like AskNature.org bring the diversity of life to the fingertips of engineers, artists and entrepreneurs. Companies like Biomimicry 3.8 offer biologists and chemists as consultants to reshape the way entire systems function, such as a carpet factory that functions more like a complete ecosystem. With roof gardens and wetlands built into the actual infrastructure of the factory, Biomimicry 3.8 has not only helped carpet manufacturer Interface reduce its environmental impact, but also provide local water purification and carbon sequestration. When the environment benefits, improved human health and worker productivity is soon to follow as well.

Advanced modern tools now allow scientists to analyze more complex systems in the natural world and adapt them for human behaviors. Computer algorithms can now track the ways ants avoid traffic jams on tiny twigs and in tight tunnels, and then project their efficiency onto traffic light systems and road infrastructure. We can improve our lives by mimicking not only the physical forms of nature, but also natures processes at an ecosystem scale.

Biological inspiration is a ray of hope that the global community desperately needs. Public awareness of natures applicability could usher in a new appreciation for the environment at a time when exploitation is at an all-time high. Medicine, food, water and energy systems all derive from nature. Biomimicry can help us shift from just harnessing natures resources to integrating natures already sustainable pathways into society.

Nature is a Rolodex of efficiency, but not every application of biomimicry is necessarily productive for combating climate change. For instance, ant-like traffic systems that save time by streamlining commutes actually enable more cars to move through the same space, thus intensifying the carbon emissions and fuel demands that destroy the environment. We should be conscious that failures are part of the biomimicry process after all, thats how adaptation leads to evolution. The survival of the fittest ideas will ultimately limit inefficiency.

With human spaces overtaking natural habitat, industrial factories spewing greenhouse gases into the air, excessive waste habits and widespread pollution, its no surprise that the planet is undergoing a sixth mass extinction. The World Wildlife Fund estimates that 60 percent of Earths biodiversity was lost from 1970 to 2014. We need to fundamentally change our behavior before its too late: the very design blueprints that could secure a better future might disappear before we even know it.

Its time to be more sustainable than just passing up on plastic straws. We can revolutionize the way we interact with each other and the planet by learning from evolution. Its smug of us to ignore 3.8 billion years of sustainable development as we urgently seek solutions for a better future. Lets think more like nature. Its time to adapt.

Isabelle Seckler is a first-year student studying sustainable development at Columbia College.

Is John Bolton Withholding Impeachment Evidence so He Can Put It in a Book? – HillReporter.com

John Bolton, Donald Trumps former National Security Adviser has been a familiar name throughout the impeachment inquiry. Bolton has played coy and hinted that he may have information that could be impactful during the upcoming trial.

While the former White House adviser has said that he would testify if subpoenaed, that it unlikely with a Republican majority. Shortly after leaving Washington DC, Bolton signed a book deal with Simon & Schuster. During Friday nights episode of Hardball, Chris Matthews and former Federal Prosecutor Glenn Kirschner talked about the possibility that Bolton could hold back important information for his book.

Matthews asked Kirschner, Lets talk about human behavior. Could it be I dont know Bolton personally, I know his politics, his ideology but could it be that he says, I thought for a while I wanted to save some of the goodies for my book, because people like to do that, people like to write the big story with the big news, but if history comes down that I sat on this stuff for a year while we didnt have a real trial, Im guilty of really withholding my citizenship here.

Kirschner pulled no punches with his answer. He told Matthews, Exactly, he said. If he had blockbuster evidence and he doesnt testify and then he puts in a book information that could have changed the course of a Senate impeachment trial, he will go down in history as a traitor and a villain.

Sustainable vs. Social Trails: Why You Should Ignore Psychology and Take the Road Most Traveled – Modern Conservationist

Imagine a different interpretation of Robert Frosts famous poem The Road Not Taken a less romantic, more clear-cut version. The subject, instead of a young man beset by the decision of which direction to take in life, is simply a hiker tempted by the prospect of a spectacular view or befuddled by poor trail markings. The first trail is part of an established trail system; the second less traveled one, an informal trail created over time by lost or overly curious hikers.

The name given to informal trails created by erosion from human foot traffic, social trails have led even the most environmentally or conservation-minded among us astray when the prospect of a beautiful sight, or promising future in Frosts case, have been simply too tempting to ignore.

Social trails often begin with a recreationist attempting to meet a need that isnt being met by an existing trail, says Shawn Burn, a psychology professor at California Polytechnic State University whose research has focused on the psychology of environmental sustainability. That may be a desire for a special view or an intentional desire to follow a game trail or view wildlife. They can even begin by people going off trail to take a wee, she notes. But sometimes its an error. They mistake a game trail for the path, or trails are poorly marked.

A lack of education and differences in environmental values influence individuals decision around whether to follow these routes as well. People vary in their environmental values, Burn says. This affects their environmental concern and how they behave in natural resource settings.

Its also true that people might know its not the real trail but figure, Why should I lose out if everybody else is breaking the rule? I might as well benefit.

Well-established social trails may indicate to some hikers, especially those unfamiliar with an area, that they too should go that way or that its the correct route.

Perhaps FOMO (fear of missing out) is sometimes a factor. After all, the social trail may suggest that theres something good that way, explains Burn. But its also true that people might know its not the real trail but figure, Why should I lose out if everybody else is breaking the rule? I might as well benefit.

Such behavior, however, often has unnoticeable consequences on that natural setting. Research has shown that outdoor recreation in general not just social trails can and often does negatively affect wildlife. Human presence can startle animals, leading to increased stress levels and causing them to burn energy reserves, which are particularly dire during cold winter months. This can also result in animals displacement and reduced productivity and, in the worse cases, even decrease their chances of survival.

For plants, its a similar story.

As social trails are used more and more, the soil becomes increasingly compacted so that the plants that used to grow there are no longer able to.

When the native species arent able to come back because of that soil compaction, often the species that are best suited to grow in those situations are non-native, and as people continue to use the corridor to walk, ride their horse or bike, they start to transport those non-native seeds further into the area, says Scott Linnenburger, principal and owner of Kay-Linn Enterprises, a consulting firm that offers sustainable recreation and conservation planning, design and construction services.

If we start to play the choose-your-own-adventure game, and everybody goes wherever they want, however they want, we start to degrade that resource quality and the landscapes ability to function naturally and then it comes into question why it was conserved in the first place, Linnenburger says.

Sustainable Trails

While recreation and conservation often seem at odds with one another, thats only when viewed through a narrow lense. There is a way to reconcile both desires that allows for the conservation of the land and resources and our ability to enjoy them. Its about ensuring minimal impact while getting people where they want to go, Linnenburger notes.

One of my mentors in trail development often says, Its not people that need trails; its the land that does, he says. We are able to get to wherever we need to get to on the landscape, but if we do that in an unmanaged, unplanned way, the impacts that we have on that landscape are magnified by every unnecessary trail thats out there.

The negative effects of social trails underscore the importance of well-marked, maintained and sustainably built trail systems those that are purposefully developed. A designated trail system, [one thats] well planned, designed, constructed and maintained, minimizes the human impact on the landscape thats been conserved, Linnenburger says.

A sustainable trail system is one that is able to withstand the erosive powers of water and wind to provide a tread surface that will sustain over time without appreciable damage, he notes. More broadly, sustainable trails are in the social or managerial context trails that take people where they want to go, that are easily navigable, that can be effectively maintained over time by a land managing agency and volunteer stewards.

People want to have a sense of adventure and maybe even danger on their trails, so trying to buffer that human emotion is often unsuccessful.

Designing sustainable trails is Linnenburgers specialty. A masters degree in environmental management and a background in stream and wetland ecology have aided him in his work with the Professional Trail Builders Association (PTBA) for which his company Kay-Linn Enterprises provides the contractual staff. The only private sector group of professional trail contractors, designers and consultants, representing more than 100 member companies worldwide, PTBA emphasizes sustainable trail development, even hosting a Sustainable Trails Conference every spring.

So, what goes into planning and constructing a sustainable trail?

I think its probably easier to characterize what sustainable trails typically have not been over time, Linnenburger says.

The vast majority of the trail miles in the United States are actually converted industrial routes: logging or carriage roads, railroad grades or open utility corridors.

As industrial routes, those were meant to bring people and/or materials from point A to point B in the most expedited manner, Linnenburger says. That meant they typically went straight up and down hills or stripped through some place that was low and wet because it was the minimum distance needing to be covered to make that industry happen.

As such, they werent ever planned around aspects of natural resources or for sustainable design and water-shedding characteristics that a trail really needs, he explains.

The first step in developing a sustainable trail is determining what the purpose of said trail is and where its intended to take people. Then comes mapping the route so that it mimics nature as much as is possible i.e., it runs parallel to topographic contours rather than perpendicular. By doing so, Linnenburger says, you are placing the trail in a location where its hydrologically invisible, meaning it wont be capable of carrying much water or producing much erosion. Considering sensitive species and their habitat, such as wetlands and waterways, as well as migration routes is also critical.

But from the outset, Linnenburger notes, its imperative to understand that a trail needs to get people to where they want to go; otherwise, well lose the battle. Ultimately, people will get where they want to go (i.e., to beautiful sights and views, like waterfalls or canyons) whether a trail takes them there or not.

Balancing Interests

Creating sustainable trail systems is thus a delicate balancing act. Considering the desires of recreationists and the sites theyll want to see as well as environmental concern for plants and wildlife, in addition to balancing individuals safety with their thirst for adventure, can be tricky.

While maintaining public safety is important across all outdoor recreation activities, many people go outside for a sense of adventure and even a sense of a lack of safety, Linnenburger says. People want to have a sense of adventure and maybe even danger on their trails, so trying to buffer that human emotion is often unsuccessful.

Taming human desire is the hardest part, particularly when it comes to closing off existing social routes.

Theres a heavy psychology aspect to closing trails because people have kind of an inherent relationship with trails and they feel like its theirs, says Linnenburger.

Thus, closing off these routes requires more than just raking plant debris over an old social trail or putting up a No Trespassing sign, says Aaryn Kay, director of operations for PTBA. You have to make that social trail disappear from everybodys memory and vision as youre trying to create these more sustainable routes, she says.

We tell folks that with the redesign or re-location of a trail, that experience has to be better than what the experience of the closed trail was. If it doesnt provide the same experience or better, the old trail will be reopened.

Thats not to say that a fence shouldnt be installed temporarily while a trail is being restored to its natural state. It shouldnt, however, be the only approach taken by land managers, Linnenburger says. Research has demonstrated that a fence doesnt close a trail, but vegetation or a fenced barrier with some communication is the most effective way, he explains.

More than letting recreationists know that a trail is closed, land managers should explain the reason for the closure, the importance of re-creating the trail in a more sustainable way and the resulting benefits for plants, wildlife and people.

Often, we tell folks who are having to do these trail closures that with the redesign or re-location of a trail, that experience has to be better than what the experience of the closed trail was, says Linnenburger. If it doesnt provide the same experience or better, the old trail will be reopened.

Kay believes that interpretive signage, when done right, can help appeal to peoples better selves.

People want to do the right thing, says Kay. So if [a sign] just says Trail Closed, its like well, why? But if you have a reason, like due to wildlife concerns or for restoration, there are ways to craft effective language.

Traditionally, however, land management agencies approach has been more command-control, according to Linnenburger. They often think putting up a sign that says Trail closed. Trespassing punishable by this kind of a fine. is a good way to reach people, he says, but thats not really meeting the recreationists on their own terms.

Educating recreationists about the landscape that its not just an open palette to go wherever you want, says Linnenburger and that its being managed for multiple purposes, including conservation, is perhaps a better, more effective approach.

Interpretive signage and pamphlets should emphasize the fragility of the ecosystem and the importance of staying on marked trails so that the area can be preserved for human visitors and its non-human inhabitants, says Burn, who is the creator of the Proenvironmental Behavior Change Model, which she used to develop the Environmental Intervention Handbook.

A tool for resource managers, available from the USDA Forest Service, the handbook is designed to help resource managers apply psychological research on sustainable behavior to solve human behavior problems in natural resource settings.

Even with such resources available, Linnenburger says, you dont see a lot of educational outreach. He attributes this to dwindling budgets and, as a result, minimal ranger presence on the landscape not to mention a lack of psychological prowess.

Its a delicate psychological balance [in which], frankly, if youre trained to manage a forest or manage for wildlife on a piece of land, you dont likely have training in sociology and psychology that allows you to kind of parse those nuances for the people visiting your lands, Linnenburger says.

That is where volunteers and nonprofits have a role to play. For agencies struggling with dwindling budgets and staff, these groups can help serve as their boots on the ground a kind of peer-to-peer approach to responsible recreation.

Utilizing the folks who are most concerned and already drinking the Kool-Aid so to speak in terms of the goals of the trail system and managing the resources that are on those lands is a great approach, says Linnenburger. People talking to people is much more effective than somebody in a uniform talking to people and saying the same things.

I met Samsungs artificial humans, and they showed me the future of A.I. – Digital Trends

Andy Boxall/DigitalTrends

This story is part of our continuing coverage of CES 2020, including tech and gadgets from the showroom floor.

What is Neon? Shrouded in mystery leading up to CES 2020, all we knew was that Neon had something to do with artificial intelligence. Was it a Google Assistant competitor? A robot? Something more?

Its a preview of a wonderful technology we have, and a wonderful future we can create together, Neons CEO Pranav Mistry said at the start of his keynote presentation.

So what is it? Its not hyperbole, for a start. Neon is a step closer to living with a digital creation that not only understands and emotes with us in a meaningful and relatable way, but is also able to create valuable memories with us and truly share our lives.

Explaining exactly what Neon is, how it works, and the incredible depth of technology underlying it is a considerable challenge and one that Neon itself isnt quite sure how to tackle. To help introduce Neon, Mistry started out by saying he wants to change the way we interact with machines, and no longer say just, Stop, Next song, or even, Hey Google, Bixby, or Siri, because its not how we talk to humans.

Mistry said he wants to push the boundaries so machines understand more about us. Whether we are tired or happy, our expressions, and our emotions.

In turn, the more machines understand us, the more we will be able to connect with them on a deeper, human level. He believes the path to this means machines need to look and act more like us, and this is where Neons journey really began.

The CES demonstration came just four months after the project started. Mistry and the team began by creating a digital version of a friend, which closely emulated his facial movements during conversation. This evolved into larger, grander tests until eventually, the digital version began to do things on its own. It would make expressions the real person had not. It had learned, and become something individual.

The Neon booth in Central Hall at CES is covered in large screens showing people on them, all moving, smiling, laughing, or silently mouthing words to the audience. Except these arent videos. These are Neons. They are digital creations born from real people, and although they visually represent the model on which theyre based, the movements, expressions, and emotions are entirely automatically generated.

Once you understood this, it was surreal walking around the booth, looking at the Neons who in turn are looking at you, and now understanding the movements they made were of their own doing, not a repeating video or animation. What was powering the Neon, and what did Mistry have in mind for their future?

The Neons are generated by the companys own reality engine called Core R3. The R3 name refers to the principals on which the system is based reality, real time, and responsiveness, and its the combination of all these that bring the Neon to life. Its not an intelligent system, says Mistry, because it does not have the ability to learn or remember. Instead, its equal parts behavioral neural network and computational reality that independently generates the Neons personality by training it to emulate human behavior on a visual level how your head moves when youre happy, what your mouth does when youre surprised, for example.

Once it has been created, Core R3 does not then continually run a Neon. It generates it initially, then the Neon continually relies on its own information to react based on its interactions with the real world. However, it doesnt know you or remember you. It uses a combination of the Core R3-generated Neon, cameras, and other sensors to interact with us in the moment but once that moment is over, everything is forgotten. In the near future, the company has big plans to change that.

Despite only being worked on for four months, there was a live demonstration of what a Neon can do now. There are two states for Neons currently, an auto mode where it does what it wants, whether it is thinking, responding, idling, or greeting you, plus a live mode where the Neon can be controlled remotely.

The Neon has multiple ways to respond and can choose how to do so, even when instructed to do a particular action. Tell it to smile and be happy, and it does so, but it chooses the way it will look when it does. The level of granular control is impressive, right down to eyebrow movement and the closing of eyes, along with head movements and both visual and verbal responses. This all happens with a response time of 20 milliseconds (the real-time aspect of R3), which removes the barrier between human and machine even further during any interaction. Speech is not produced by Neon at the moment, and in the demo, voice was pulled from third-party APIs, giving life to artificially intelligent voice assistants and chatbots everywhere.

The Neon is domain independent, Mistry said. A Neon could teach you yoga or it could help bridge language gaps around the world, for example. Potential uses for a Neon in business are obvious, such as in hotels, at the airport, or in public spaces. The Neon is an evolution of the clunky robots or lifeless video screens seen in these places around the world at the moment. But thats not really very exciting, and certainly not the part of the Neon thats truly groundbreaking.

Right now, a Neon cannot know who you are or remember you. Once your interaction is over, your relationship with it is lost to the digital ether. However, over the next year, the Neon team will work on the next version of Core R3, along with a project called Spectra that will add these important traits to Neon, and arguably bring it to life.

Spectra will provide memory and learning, Mistry told us, revealing the true direction of Neon.

By adding memory and the ability to learn, along with the advanced human-like visuals, a Neon has the potential to become a true digital companion. Speaking to Mistry after the presentation, his eyes lit up as he talked about the characters he loved as a child, and that the connection he had with them was not affected by the fact they were not real. A fully fledged Neon could bring similar joy to people, in a stronger and even more personal way.

What Neon showed at CES 2020 is very much the beginning, but theres clearly a massive amount of investment, belief, and talent involved. Not many companies would have the guts to come to Las Vegas and show off a four-month-old demo after a few weeks of hyping it up. Mistry has worked with Microsoft on the Xbox, and with Samsung on the Gear VR in the past. Hes soft-spoken and charismatic, and everyone we spoke to at Neon had a similarly strong belief in what the company is doing.

It was contagious, especially if youve had sci-fi dreams about artificial humans and digital companions all your life.

However, there is a lot to consider before youre picking out a name for your first Neon pal. How will the Neon come to life for you and me? Mistry, in true visionary fashion, was not concerned by such things. In his presentation, when talking about the importance of thinking big to do something amazing, he said:

We dont understand whats the business model of something, or how we will bring something to market, lets figure that out later.

A Neon team member talked to us about how the company intends to create Neons in the future. They wont use real people as models, and instead generate their own looks for Neons. Think about that for a moment: An entirely artificial digital human, with its own unique looks, and the ability to speak, emote, learn, and remember. It gives me a shiver, its so exciting.

Given the pace with which Core R3 has evolved already, its no surprise to hear Mistry intends to show the first beta version of a Neon, as well as a preview of Spectra, sometime in the next 12 months at an as-yet-undefined event called Neon 2020. What Neon showed at CES is a huge leap forward in avoiding the uncanny valley, changing the way we should think about digital humans. Its a major step toward giving life to something that naturally does not have any. Theres a long, long way to go before the Neon reaches its potential, but the very fact the journey has started at all is thrilling.

Stretched Too Thin by Social Media – Scientific American

In the past two months, I received multiple invitations to leave Facebook and Twitter and join a new social network that promises to not destroy democracy. Im tempted. Im also tempted to delete my accounts and abandon social media altogether. The decision got me thinking, not about democracy but instead about how social media affect my behavior and relationships.

Social media promise and deliver social networks with better or at least bigger scale and scope. Essentially, this means you can connect to many more people from many different places to relate on a wider variety of interests. To socialize is a core human need. The difficult question is whether social media improve our capability to relate to each other.

The answer may seem obvious. Social media afford connectivity, engagement and relationship management at such incredible scale and in such a convenient manner. It must be a substantial improvement. Most social media users can attest to the power. Many will recall that thrill of finding lost friends, connecting with distant colleagues, or maintaining relationships that would otherwise be forgotten or just lost.

Yet, paradoxically, the feeling of power may, like the rush from an intoxicant, blind users to deleterious consequences. Social media can be vampiric on human attention, empathy and care. Consider the ad-based business model upon which most social media depend. Attention is bought and sold. Social media serve as the gateway to behavioral data extraction while delivering targeted stimuliwhether ads or inducements to keep you glued to the platform.

We only have so much time, energy and attention to devote to our relationships, to make them meaningful.

Social media change how we relate to each other. But are we better or worse off? To evaluate that question, we need baselines.

Without social media, people have many different social networks, from intimate to professional. Consider the most intimate social network, your family. Families are social networks where, in network lingo, family members are the nodes, and the ties (sometimes called links) between nodes may be stronger/weaker based on the relationship between nodes. Thus, parent-child and sibling ties are much stronger than distant cousin ties.

When my wife and I got engaged, we would tell folks that we planned to have a large family. I grew up with seven siblings, and that gave me a benchmark. My wife had two siblings and many close cousins, and she worked with children. We figured we would have six or more children!

We now have three boys and do not plan on having any more. After transitioning from man-to-man to zone defense, we realized that three was more than enough. We could only afford that many. And not just financially. Honestly, if we had infinite financial, emotional and other resources and we ignored broader environmental considerations, we would love to have more children. But scarcity is a fact of life, despite what some abundance evangelists preach.

My wife and I realized that with three children, our attention was spread as far as we thought was appropriate for us to be meaningfully in engaged in our childrens and our own lives. Our immediate family of five sustains strong ties. We worried that expanding our network would risk weakening them. Of course, we never used those words! We would say we didnt want to stretch ourselves too thin.

Lately, this is how I feel when I am use social media platformsstretched too thin, maintaining relationships with large numbers of weak ties, often though not always with superficial forms of engagement. Worse, I find myself devoting time, attention and effort to people with whom I have no actual tie at all. Even weaker than weak ties are the nonexisting relationships, the potential ties many of us find ourselves catering to on social media platforms. Potential followers, a potential audience, people who follow people who follow me who just might receive a shared post or tweet. It sounds ridiculous when actually written, doesnt it? Yet if you use social media platforms, you probably know what Im talking about.

Whats so bad about being stretched thin? Well, there are trade-offs, which vary for different people. In general, Im concerned with the impact on strong ties, our most important and meaningful relationships. Being stretched too thin may weaken strong ties, lead to fewer strong ties, or both. This is the most obvious effect to look out for, but there are other relationships that might be impacted. Consider, for example, your moderate ties, say your co-workers or neighbors. These important relationships might be sacrificed at the social media altar as people seek affirmation and attention from much weaker, less meaningful, but more plentiful ties.

Some might say Im old-fashioned for putting driveway and watercooler conversations on a pedestal and for denigrating emoji- and click-fueled communications. Thats not really the point though. I struggle with social media too. Evaluating the trade-offs isnt easy. But an important first step is recognizing that its about more than democracy writ large, the algorithms structuring what you encounter, or the specific content in your feed. It is fundamentally about the nature and strength of the relationships you cultivate.

Self-sustaining space-inspired village is set to open in the Mojave Desert – Lonely Planet Travel News

Construction on the self-sustaining, bio-regenerative village is set to begin next year 2020 Interstellar Lab

Working under the assumption thattechnologies designed for exploring other worlds should also improve life on Earth, Interstellar Lab has designed a self-sustaining, regenerative village of biomes inspired by the conditions on Mars and in tempting news for sustainably minded travelers, itwill eventually be open to the public for overnight stays for half the year. (Of course, such access comes at a cost potentially between $3000 (3531) and $6000 (7062) per week, CEO Barbara Belvisi told Venture Beat in November.)

A testing ground for astronaut training and space-settlement tech, the closed-loop village known as EBIOS (Experimental BIOregenerative Station) will produce and recycle water, food, and energy for 100 people, leaving a carbon-neutral footprint and creating zero waste.

From water treatment [and] waste management to food production systems, we are developing solutions that can be implemented right now on Earth, and we are preparing for future settlement on other planets, Belvisi said in a press release.

It took two years of research and development, plus close collaboration with NASA on water treatment, plant-growth systems, 3D printing, and an analysis of human behavior in tight quarters, before Interstellars plans for the village were revealed. Construction is expected to begin in the Mojave Desert in 2021, and a second location at Floridas Kennedy Space Center could follow soon after.

"A long-term, sustainable Mars or lunar settlement will only be practical if we do the researchon Earth and really test the viability of different systems, Greg Autry, director of the SoCal Commercial Spaceflight Initiative and former White House Liaison at NASA, said in a press release.

From a cave in Cantabria that mimics life on Mars to an island in the Canaries that bears an uncanny resemblance to the planet to a London museum exhibit detailing what, exactly, wed need to pack to move to Mars, the red planet is certainly capturing the public imagination thanks in no small part to the increasing havoc wreaked by climate change. "The two planets share a common ground, Belvisi said. "What we need to bring on Mars for life is what we need to protect on Earth right now. The only path to become a multi-planet species is to join our energy towards the same direction.
