The Truth: Tied to Technology – The Harvard-Westlake Chronicle

Credit: Alexa Druyanoff/Chronicle

Then school starts, and we receive our daily doses of disheveled bed head and pajama tops via Zoom. For almost a quarter of each day, we sit facing the screen, filling breaks with TikTok, Snapchat and Instagram. Whether for work or for play, were constantly on our devices.

How do you start talking to someone youre interested in being more than just friends with? The first step usually begins with responding to a Snapchat story or a direct message on Instagram. The second step entails sending a daily Snapchat message. After the third stepbeing added to their private story the real-time conversations through FaceTime begin.

All three steps have one common thread tying them together: technology and, more specifically, how involved our beloved tech has become in our daily lives.

The recently released Netflix documentary The Social Dilemma lays bare the prevalence of Big Tech and its power. The sources, which include former Silicon Valley executives, add nuance to the ever-growing debate over the detrimental effects of technology on our mental health. The Social Dilemma argues that our growing addiction to the virtual world comes from the nature of technology, which is designed to create profit like any other type of corporation in America. As Facebook, Google and even Pinterest have come under the social microscope, we see that the concerns over data harvesting arent about security. These companies are the largest advertising powers in the world and use their data to predict our human behavior. In order to make sales as ad placement sellers but also to create tech companies expanded their reach and honed in on their AI systems to not only target customers, but to also create the impetus for us to buy that tennis skirt on Etsy or a new pair of AirPods. On a larger scale, this sways elections through the Facebook ad situation, like in 2016. And it looks like, with the greater integration and reliance on technology, the stakes will only get higher.

The first iPhone came out in 2007, Instagram was released in 2010 and Snapchat was developed in 2011. Gen Z is the first generation to live with this phenomenon called social media.

Look at your pinky finger on the side that you hold your phone. Compare it to your other pinky. Is there a little indent on the inside of that second ridge where you hold your phone?

Or maybe you instinctively open Snapchat or Instagram out of nervous habit when youre waiting in public. We see technology expanding its reach over us, and we have the authority to make what we want of it. The next time you wake up on the phone side of your bed, just keep this in mind.

Sugar, high-fructose corn syrup linked to ADHD, bipolar, aggressive behavior – UPI News

Oct. 16 (UPI) -- Diets high in sugar may increase a person's risk for developing attention deficit hyperactivity disorder, bipolar disorder and aggressive behaviors, according to a report published Friday by the journal Evolution and Human Behavior.

Researchers from the University of Colorado Anschutz Medical Campus suggest that fructose, a component of sugar and high-fructose corn syrup, and uric acid, a fructose metabolite, may work to bring about the onset of these disorders in those genetically predisposed to them.

By lowering energy in cells, fructose "triggers a foraging response similar to what occurs in starvation," which effectively stimulates behaviors such as risk taking, impulsivity, rapid decision making and aggressiveness, the researchers said.

This foraging response shares similarities with behavioral disorders such as ADHD, as well as bipolar disorder and aggressive behavior, they said.

"There have been many reports suggesting that sugar or other added sweeteners such as high-fructose corn syrup may be able to cause or aggravate various behavioral disorders," study co-author Dr. Richard Johnson told UPI.

"The evidence is based on the unique ability of fructose to lower energy that triggers a foraging type of response," said Johnson, a professor at the University of Colorado School of Medicine.

The theory is based on "an evolutionary-based survival pathway" used by animals to protect against starvation, according to Johnson and his colleagues.

Historically, animals and humans used this response for survival, understanding that they needed to take certain risks to obtain food and avoid starvation and death, the researchers said.

However, this survival pathway is now activated by the metabolism of fructose, leading to the storage of fat in the liver and blood, the development of insulin resistance and a decrease in energy expenditure, earlier research by Johnson and his colleagues suggested.

The introduction of refined sugar and high-fructose corn syrup into the human diet has led to a significant increase in fructose intake over the past 300 to 400 years, and Johnson and his colleagues argue that this level of intake is higher "than nature intended."

In addition to fueling epidemics in obesity and diabetes, high-fructose intake can lead to problem behaviors, as human cells seek to restore their lost energy.

The new report describes how high amounts of fructose found in refined sugars in the typical Western diet may contribute to the development of behavioral disorders.

Sugar does not cause these behaviors, however, as it's just a contributing factor, researchers emphasized.

"The identification of fructose as a risk factor does not negate the importance of genetic, familial, physical, emotional and environmental factors that shape mental health," Johnson said.

Conditions such as ADHD and bipolar disorder are genetic -- meaning they're passed from parent to child -- but they also have some "environmental components," according to Dr. L. Eugene Arnold, emeritus professor of psychiatry at Ohio State University.

"Physical and mental health ... impact each other," said Arnold, a resident expert with Children and Adults with Attention-Deficit/Hyperactivity Disorder, or CHADD, an education and advocacy organization for people with the condition and their caregivers.

Currently, CHADD doesn't offer guidance with regard to diet. However, the organization does cite research noting links between sugar intake and the worsening of ADHD symptoms.

With that in mind, Arnold recommends a diet built around "natural, whole foods," such as the Mediterranean diet.

"A rule of thumb is if the list of ingredients on a food product label is so long you don't want to read it, don't buy it," he said.

More research is needed to investigate the role of sugar and uric acid on mental health, especially with drugs designed to inhibit fructose metabolism for the treatment of diabetes and metabolic syndrome on the horizon, Johnson said.

For now, "reducing intake of sugar and high-fructose corn syrup, especially sugary beverages, may be of additional benefit in preventing or helping behavioral disorders such as ADHD and bipolar disorder," he said.

Doctors say second wave of COVID-19 infections in Florida is preventable – WTSP.com

What happens in the next months is all dependent on human behavior, experts say, with models for COVID-19 showing three different scenarios for Florida.

TAMPA, Fla A month into fall in Florida and infectious disease experts are closely monitoring the state's COVID-19 numbers.

With fewer restrictions in place, cooler temperatures and the thick of flu season on the horizon, a second wave of new coronavirus infections is expected.

In reality, it's kind of the perfect storm, Dr. Jill Roberts with USF Public Health said.

She says cases are slowly rising right now. With more than 750,000 cases reported, the state's daily percent positivity stands at 4.8 percent.

One of the reasons we pick on Florida is because we have been historically one of the earliest to sort of release all those restrictions, Roberts said. We have the potential to prove everyone wrong and we can simply do that by continuing to do what we've been doing all along. We can continue to our masks and we can continue to social distance.

Doctors say what happens in the next months is all dependent on human behavior. The models for COVID-19 in Florida, created by the College of Public Health at USF, show three different scenarios:

Model 1: Cases will go down and stay down if mask-wearing and social distancing continue.

Model 2: Everything stays how it is and cases continue to plateau.

Model 3:We act as the virus doesn't exist and cases spike because we let our guard down.

It's this third scenario is one we should work together to prevent, Dr. Marissa Levine said. The public health expert with USF Public Health says COVID-19 measures have to stay in place a little longer.

I'm not here to scare anybody, I would say that the critical public health message is, we have to keep doing what we know works. If we stopped doing that, if we increase our mobility, and we take away our protections, then we are going to see a spike we've seen. We're seeing that happen in other places in the United States, Levine said.

Doctors urge everyone to keep wearing their masks and social distancing until we find a COVID-19 vaccine.

Gov. Ron DeSantis says Florida won't shut down again even if infections rise. He wants the state to stay open and keep moving forward.

‘Safer, but not safe’ | New study looks at how COVID-19 is spread on airplanes – WWLTV.com

Keep in mind it takes 90 minutes to clear particles in the average home.

NEW ORLEANS, Louisiana The airline industry has been hit hard since the coronavirus spread to the U.S.

People are fearful of becoming infected in a closed airline cabin.

Now a new study finds it is much safer than we originally thought, but a local doctors says there are still reasons not to let your guard down.

The new study is from the U.S. Department of Defense. Using a mannequin, they found that 99.99 percent of particles, released in the air from an infected person wearing a surgical mask, were removed from an airplane cabin within six minutes.

Keep in mind it takes 90 minutes to clear particles in the average home.

So we turned to Tulane Public Health Epidemiologist Dr. Susan Hassig for her analysis.

In the perfect conditions that were indicated by the study, one is relatively safe. I think safer, but not safe, explained Dr. Susan Hassig, an Associate Professor in the Tulane School of Public Health and Tropical Medicine.

So lets look at the study limitations. The mannequin spreading the aerosol particles, never took off her mask, always faced forward, and never moved.

Now consider real human behavior.

Masks come off to eat and drink, you go to the restroom or get something out of the overhead bin, children cry and take off masks, you turn and talk to others. So, she says you still need protection.

You have to mask. You have to still be very aware of surfaces and hand contamination that you could bring your eyes, to your nose or your mouth, said Dr. Hassig.

So with these new, promising results would you now travel by air? We asked various people out doing their grocery shopping.

I just would not feel comfortable until there's a vaccine, said a man who used to travel internationally a lot before the pandemic.

It's getting better and safer. I think they take a lot of precautions for traveling people, and I think we doing a little better, said a woman who would travel.

I would not feel safe right now. I wouldn't do it, maybe probably 'til next year, said another woman.

I do would prefer if everyone wore a mask. I just feel like it controls the virus, said a woman who would travel but wants to make sure she is protected.

I'd feel safe on a plane, because if you got on a mask. I don't usually get on a flight that long, explained a young man.

And Dr. Hassig says that young mans point is important, because on a shorter flight there will most likely be fewer people moving around the cabin or taking off masks to eat meals.

The study was done in Boeing 767 and 777 aircraft. The doctor says newer aircraft will have better filtration technology.

People Trying to Control Your Mind Have More Tools Than Ever – VICE

Are you susceptible to mind control?

Both Donald Trump and Barack Obama have been accused of using some kind of hypnosis or mind control to cast a spell over unsuspecting Americans. Media companies, consolidated in ever fewer hands, can seem like cults that are brainwashing their audiences with propaganda. And online influence campaigns can lead us down dark rabbit holes, manipulate our emotions, or just trick us into buying stuff we dont need.

Of course, losing ones personal autonomy to some sinister force has taken many forms over the years.

For example, if you ever notice your head rotating a full 360 degrees or find yourself blaspheming in ancient tongues, you might be experiencing demonic possession, whichlike zombiesshow us mind controls roots in faith and folklore. But mind control goes way beyond the supernatural. Take the CIAs Project MKUltra, a series of dangerous, unethical, Cold War experiments that used torture, sensory deprivation, and drugs like LSD on thousands of subjects, aiming to perfect methods for controlling human behavior.

These days, much of the mind-control debate centers on social media, which uses little psychological rewards and punishments to condition users into new habits and behaviors. YouTube, with its reported penchant for pushing viewers toward extremist content has been called The Great Radicalizer.

The good news is that whether youre talking about politicians or would-be digital manipulators, most supposed mind-control methods dont exactly work as advertised. The bad news is that there are certainly plenty of governments, businesses, and scientists whod love to puppet you like a marionette, and theyre not likely to give up trying.

In this episode of Complexify, we got mesmerized by the world of mind-control, probing creepy street hypnotists and subliminal chicanery in an effort to master this spellbinding subject. Heres what we learned.

A Viral Theory Cited by Health Officials Draws Fire From Scientists – The New York Times

As the coronavirus pandemic erupted this spring, two Stanford University professors Dr. Jay Bhattacharya and Dr. Scott W. Atlas bonded over a shared concern that lockdowns were creating economic and societal devastation.

Now Dr. Atlas is President Trumps pandemic adviser, a powerful voice inside the White House. And Dr. Bhattacharya is one of three authors of the so-called Great Barrington Declaration, a scientific treatise that calls for allowing the coronavirus to spread naturally in order to achieve herd immunity the point at which enough people have been infected to stall transmission of the pathogen in the community.

While Dr. Atlas and administration officials have denied advocating this approach, they have praised the ideas in the declaration. The message is aligned with Mr. Trumps vocal opposition on the campaign trail to lockdowns, even as the country grapples with renewed surges of the virus.

The central proposition which, according to the declarations website, is supported by thousands of signatories who identify as science or health professionals is that to contain the coronavirus, people who are not vulnerable should immediately be allowed to resume life as normal while those at high risk are protected from infection.

Younger Americans should return to workplaces, schools, shops and restaurants, while older Americans would remain cloistered from the virus as it spreads, receiving such services as grocery deliveries and medical care.

Eventually so many younger Americans will have been exposed, and presumably will have developed some immunity, that the virus will not be able to maintain its hold on the communities, the declaration contends.

But it does not offer details on how the strategy would work in practice. Dr. Anthony Fauci, the governments top infectious disease expert, has dismissed the declaration as unscientific, dangerous and total nonsense. Others have called it unethical, particularly for multigenerational families and communities of color.

Alarmed and angry, 80 experts on Wednesday published a manifesto of their own, the John Snow Memorandum (named after a legendary epidemiologist), saying that the declarations approach would endanger Americans who have underlying conditions that put them at high risk from severe Covid-19 at least one-third of U.S. citizens, by most estimates and result in perhaps a half-million deaths.

I think its wrong, I think its unsafe, I think it invites people to act in ways that have the potential to do an enormous amount of harm, said Dr. Rochelle Walensky, an infectious disease expert at Harvard University and one of the signatories to the Snow memo. You dont roll out disease you roll out vaccination.

The declaration grew out of a gathering hosted in Great Barrington, Mass., by the American Institute for Economic Research, a think tank dedicated to free-market principles that partners with the Charles Koch Institute, founded by the billionaire industrialist to provide support to libertarian-leaning causes and organizations.

On Oct. 5, the day after the declaration was made public, the three authors Dr. Bhattacharya, Sunetra Gupta of Oxford University and Martin Kulldorff of Harvard arrived in Washington at the invitation of Dr. Atlas to present their plan to a small but powerful audience: the health and human services secretary, Alex M. Azar II.

Over the course of an hourlong meeting in a wood-paneled, sixth-floor suite atop the health departments headquarters, the researchers walked the secretary and Dr. Atlas through their thinking.

Mr. Azar later tweeted: We heard strong reinforcement of the Trump Administrations strategy of aggressively protecting the vulnerable while opening schools and the workplace.

Battered by lost jobs, pandemic fatigue and isolation, and worried for their children, there is little doubt that Americans loathe lockdowns, although many still see them as necessary to control the virus.

Among scientists, too, there is near-universal agreement that lockdowns are harmful. Even Dr. Fauci has suggested that another national lockdown must be instituted only as a last resort.

But mostly, scientific disagreement centers on whether lockdowns are a necessary move when other strategies to contain the virus have not even been put in place, or have failed.

This has been wrongly framed as a debate between lockdown and no lockdown, said Dr. Deepti Gurdasani, a clinical epidemiologist at Queen Mary University of London.

Dr. David Nabarro, a special envoy to the World Health Organization, has urged governments not to resort to lockdowns as the primary method to control the virus. Masks, social distancing, fewer crowds, testing and tracing these are the ways to control the virus in the long run, he said in an interview.

But the lockdowns in the spring were necessary, he added, as emergency measures to give countries time to put in place strategies to control the virus.

There is a middle way, Dr. Nabarro added, between strict lockdowns and letting the virus freely infect people. If only we had a few more world leaders who would understand this, we wouldnt have this debate going on.

But Dr. Bhattacharya and his supporters go further. They say that governments should never have imposed lockdowns at all, and never should have tried to institute coronavirus testing and contact-tracing. Instead, the trillions of dollars in economic aid approved by Congress should have been spent on programs to protect those at highest risk of illness and death.

The manifestos central tenet is that young people should be free to resume normal life to re-enter the work force, attend college, dine in restaurants. They would become infected, hopefully without much illness, and gain immunity.

Eventually the virus would not be able to find new victims and would fade away.

People who are more at risk may participate if they wish, while society as a whole enjoys the protection conferred upon the vulnerable by those who have built up herd immunity, the declaration said.

The strategy includes keeping older people cloistered, with regular testing to detect possible outbreaks in nursing homes, and with groceries and other necessities delivered to anyone over 60 sheltering at home. Alternately, older people might move to other facilities for isolation or quarantine.

There would be no widespread surveillance for the coronavirus. People would be given information about testing, with an emphasis on those who have symptoms but when and how to get tested, and whether to isolate if infected, would be left up to individuals.

Testing and isolating indiscriminately causes too much collateral damage for it to be useful, Dr. Bhattacharya said.

But some experts said the strategy was highly impractical, given the difficulty in determining who is truly susceptible. The risk of death from Covid-19 rises sharply with age, but about 37 percent of adults in America also are at significant risk because of obesity, diabetes or other underlying conditions.

The most recent statistics indicate that 20 percent of deaths from Covid-19 occur in people under age 65. And about a third of people who have recovered from the disease, including the young, still struggle with symptoms weeks later (a phenomenon the Barrington authors contest). Its amazingly irresponsible not to take these risks into account, Dr. Nabarro said.

The declarations strategy is both unethical and fails to account for human behavior, said Ruth Faden, a bioethicist at Johns Hopkins University.

Many high-risk groups people who live in multigenerational families or in crowded living situations, or who have diabetes and obesity are disproportionately found in poor communities, she said. The declarations strategy would require them to move away from their families or to risk having younger family members bring the virus home.

Are we going to compel these people to leave? And if were not going to compel them to leave, then hows this supposed to go? she said. Then you are going to see the deaths that you say were not going to see.

Reopening schools when community levels of the virus are high similarly rests on a misguided assumption that parents and teachers would agree to the strategy, she added.

Scientists who have signed the declaration did not offer many details for putting its ideas in place.

I dont know exactly how it would work, said Gabriela Gomes, a mathematical modeler at the University of Strathclyde in Britain and one of 42 co-signers.

Another supporter, Paul McKeigue, a genetic epidemiologist at the University of Edinburgh in Scotland, said, Specific control measures for preventing coronavirus transmission are not my area of expertise.

The lack of a clear plan has turned away even some would-be supporters. Dr. Stefan Baral, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health, attended part of the Great Barrington, Mass., meeting and said he was sympathetic to the effort.

But Dr. Baral, a Swedish citizen who supports that countrys approach, said he did not sign the declaration because it did not lay out a plan for workplace or housing accommodations for people at risk.

Sweden adopted an unrestrictive approach, offering guidelines to its citizens but leaving compliance up to them. The country is often cited as the model for controlling the virus without restrictions, but has among the highest death rates in the world, particularly among the elderly. It has also suffered economic losses comparable to those of other Nordic countries.

Its possible to avoid even those risks without lockdowns if governments impose some reasonable restrictions like physical distancing and universal masks and install test and trace strategies, Dr. Nabarro said.

I will contest anybody who says it is undoable, he added. Its doable without collateral damage if you bring together all the local communities.

The town of Great Barrington, Mass., home to the American Institute for Economic Research, recently distanced itself from the declaration, saying the strategy it proposed could cost millions of lives.

Anyone who might avoid Great Barrington, due to confusion over the Declaration, is invited to visit and see how COVID-safe works in a small New England town, the towns leaders wrote.

Please wear a mask.

Are Trinity and its Constituents Protecting the Nest? – The Trinity Tripod

Jack Carroll 24

Staff Writer

Given the recent surge in positive COVID-19 cases in the last two weeks, as well as the Colleges struggle to contain the spread of the virus at Trinity, it could be potentially harmful for students to remain on campus for the fall semester unless conditions change.

As the COVID-19 dashboard recently reported an ominous total of 56 active cases (down to 18 at the time of this writing), it is evident that the reopening plansthe consequences of which are not yet fully understoodhave so far been ineffective in preventing the contraction and spread of the deadly virus that has already claimed the lives of more than 219,000 people in the United States alone.

Before going any further it would be unfair to assign the entire weight of responsibility for the rise in cases to the reopening plans. Any current student with a pair of eyes, a smartphone, and a tinge of common sense would be able to realize that the careless behavior of some students have not helped the College in its dying effort to Protect the Nest.

Indeed, if Trinity is a nest, then the nest has become littered and sickened with White Claws, discarded masks, and respiratory illness.

Nonetheless, last summer, Trinity joined many other institutions across the country in making the decision to reopen in the admirable attempt to provide its students with a quality education and a sense of community amidst the extremely difficult circumstances. However, there have been some challenges up to this point.

The Tripod recently reported that infected students were sent to quarantine on the same floor as non-infected students in the Stowe and Clemens dormitories. It was also reported that this move was made without any prior warnings or notifications to residents of either of these dormitories. In addition, the one student, one room idea for student housing was apparently revised.

It is further worth highlighting that the previous decisions essentially reintroduce any of the averted health risks from the social-distancing and mask mandates outlined in the Community Contractwhich is, in reality, a five page document which has proven to have as little influence on human behavior as a United Nations resolution calling for world peace.

Since some seem to have forgotten the implications and potential outcomes of the illness on the community, it is evident that the failure of some to recognize the virus as a threat to those on and off campus has played a role in the conditions that have developed to date.

Amongst those who have not been impacted by the virus, it is often not regarded as a severe illness. Many unaffected people tend to view the COVID-19 pandemic as an abstract phenomenon that only threatens the elderly, residents of crowded cities, and patients in nursing homes.This is far from the truth.

To those who think that their luck makes them more knowledgeable than medical experts at Johns Hopkins and the Centers for Disease Control, it is important to take the time to do some reading on how the virus has impacted the lives of certain individuals and families across the country.

In September, a sophomore at Appalachian State University in North Carolina passed away after suffering from neurological complications caused by the coronavirus. Disturbingly enough, ASU is still open today and its COVID-19 dashboard dismally reported over 100 active daily cases at the time this piece was written.

In New York City, where the virus has lead to the death of over 33,000 residents (which, for a sense of proportion, is the equivalent to the disappearance of the entire student body of UConn amongst each of its schools and campuses), coronavirus-stricken corpses were wrapped in orange body bags and placed in the hallways of the Wyckoff Hospital in Brooklyn in the months following the initial outbreak of the pandemic.

Also, in the spring of this year, an emergency room doctor at a Manhattan hospital committed suicide after heroically working at the forefront of the COVID-19 pandemic in one of the most affected cities in the country.

These real-life and devastating accounts hardly scratch the surface of the endless suffering that comprises the ever-rising COVID-19 statistics. Speaking of which, at the time this article was written, the Johns Hopkins COVID-19 Dashboard reported over 8 million confirmed cases in the U.S. and over 39 million globally.

It was recently reported in The Wall Street Journal that the U.S. reached the highest level of daily cases since mid-August this past Wednesday. In the same article, it was also reported that the data from the University of Washingtons Institute for Health Metrics and Evaluation estimates that an additional 180,000 deaths could occur in the U.S. by February.

On Oct. 15, the Hartford Courant released data from Governor Ned Lamont that identified the city of Hartford as one of 11 coronavirus hotspots in Connecticut.

As far as students such as myself are concerned, it is evident that many are eager to enjoy a rewarding college experience. Despite my frustrations with some of the behavior that has taken place, I have the utmost empathy for my peers as we have all had our high school graduations and first semesters of college hindered by such devastating and unprecedented conditions.

Nonetheless, given the COVID-19 case count at Trinity and its continual ebb and flow, as well as the fact that there is not a vaccine that is going to be available in the near future, the question now becomes: How will we protect the nest? If the case count continues along an upwards trajectory, it could become increasingly possible that instruction moves online at some point during the school year.

As I continue my studies during the fall semester, I will reserve my ambivalent thoughts about the current state of affairs at Trinity. Most of all, I wish a swift recovery for my on-campus peers who are infected with COVID-19, and a productive end to the semester for everyone.

Researchers Examine Effects of Repeated Droughts on Different Kinds of Forests – Noozhawk

Anna-Trugman

Drought is endemic to the American West, along with heatwaves and intense wildfires. But scientists are only beginning to understand how the effects of multiple droughts can compound to affect forests differently than a single drought alone.

UC Santa Barbara forest ecologist Anna Trugman along with her colleagues at the University of Utah, Stanford University and the U.S. Forest Service investigated the effects of repeated, extreme droughts on various types of forests around the globe.

They found that a variety of factors can increase and decrease a forests resilience to subsequent droughts. However, the study, published in Nature Climate Change, concluded that successive droughts are generally increasingly detrimental to forests, even when each drought was no more extreme than the initial one.

Droughts usually leave individual trees more vulnerable to subsequent droughts. Compounding extreme events can be really stressful on forests and trees, said Trugman, an assistant professor in the Department of Geography.

She compares the experience to a person battling an illness: Youll be harder hit if you get sick again while youre still recovering.

That said, the case is not quite so clear cut. Theoretically, responses to subsequent droughts could be quite varied depending on a wide range of tree-level and ecosystem-level factors, said lead author William Anderegg, an assistant professor at the University of Utah.

So, while a drought may place a tree under considerable stress, it could also kill off some of its neighbors, leaving the survivors with less competition for water should arid conditions return.

Trugman and her colleagues used a variety of data sources to investigate this effect on a broad scale. Tree ring data spanning over 100 years enabled them to see how trees that survived an initial drought grew afterward.

Data from the U.S. Forest Inventory and Analysis gave them access to metrics on tree mortality for more than 100,000 forest plots from 2000 through 2018. They combined these sources with satellite measurements of the water content in forest canopies.

Two clear tends emerged. We found that generally trees seem to become more vulnerable to stress after multiple droughts, especially conifers, Anderegg said.

The second finding, the researchers believe, comes down to basic physiology. Conifers and their kin have different vascular systems than broadleaf trees, or angiosperms. As a result, they may sustain more damage in an initial drought and be at a disadvantage compared to angiosperms during subsequent periods of drought stress.

The tree ring data bears this out, showing conifers that survived a drought grew much more slowly, especially if another drought settled in.

By contrast, angiosperms have much more flexible anatomy and physiology, and this seems to help them recover faster and more fully after initial droughts, Anderegg said.

Anderegg was particularly surprised by the impact repeated drought had on the Amazon Rainforest. We tend to think of these forests as not very impacted by drought and, due to their high tree diversity, able to recover quickly, he said. But our results indicate the Amazon has been hit hard by three very severe droughts in the past 15 years.

Forests are complex systems, and a variety of factors ultimately dictate how they respond to extreme events.

In terms of damage you need to not only think about it at the individual level, but at the forest level as well, said Trugman. So, while they will need time to recover from an extreme drought, surviving trees will face less competition for water resources than before. This could leave them in a better situation if drought returns to the area.

Whats more, natural selection will drive the forest as a whole to transition toward more resilient individuals, or even to more drought tolerant species overall. Repeated droughts affect forest pests and pathogens as well, and their response to these conditions will also influence how forests behave.

Scientists are still working to untangle the conditions under which each of these factors rises to the top. This [study] provides a lot of motivation, said Trugman, but I think the next pressing step is to get at the underlying mechanisms at a physiological level and ecological level.

Researchers can use these insights to improve computer models and make more accurate forecasts about the future of forests in a changing climate. Climate change is going to bring more frequent droughts, Anderegg said. So we have to understand and be able to forecast how forests will respond to multiple droughts.

These results are especially crucial in the western U.S., where we've had a number of major droughts in the past 20 years.

Abstract: Artificial intelligence (AI) pertains to the ability of computers or computer-controlled machines to perform activities that demand the cognitive function and performance level of the human brain. The use of AI in medicine and health care is growing rapidly, significantly impacting areas such as medical diagnostics, drug development, treatment personalization, supportive health services, genomics, and public health management. AI offers several advantages; however, its rampant rise in health care also raises concerns regarding legal liability, ethics, and data privacy. Technological singularity (TS) is a hypothetical future point in time when AI will surpass human intelligence. If it occurs, TS in health care would imply the replacement of human medical practitioners with AI-guided robots and peripheral systems. Considering the pace at which technological advances are taking place in the arena of AI, and the pace at which AI is being integrated with health care systems, it is not be unreasonable to believe that TS in health care might occur in the near future and that AI-enabled services will profoundly augment the capabilities of doctors, if not completely replace them. There is a need to understand the associated challenges so that we may better prepare the health care system and society to embrace such a change if it happens.
