Fighting Ice With...Ice?
Posted in Interesting

This series of images (click to enlarge) shows an aluminum sample with elevated grooves after 0, 1, 2, and 3 hours in a supersaturated environment. You can see that the ice is contained to the elevated grooves and grows upward over time. However, the ice stripes disrupted the usual behavior. There, the ice stripes grew upward, away from the surface. For example, we’d need a method for patterning ice stripes on a large object.

Mysterious Heat Spikes inside Cells Are Probed with Tiny Diamonds
Posted in Interesting

The dispersal of that heat sets an overall body temperature, with different types of cells contributing to varying degrees. Because the fluid in cells is water-based, scientists have generally assumed it carries heat much like water does. Instead heat dissipates in cells about five times more slowly—a speed more akin to the way it dissipates in oil. Until now “nobody knew this basic property of living cells,” Suzuki says. The heat conductivity identified in the new work can explain smaller heat spikes of a couple of degrees F, though not the massive heat surge in mitochondria, Suzuki says.

How Elvis Got Americans to Accept the Polio Vaccine
Posted in Interesting

But despite the literally crippling effects of the virus and the promising results of the vaccination, many Americans simply weren’t getting vaccinated. What did prove successful was Elvis getting the vaccine in front of millions. Why might this be the case, and are there lessons that can be applied to the rollout of the COVID-19 vaccine? Elvis’s public act contained three crucial ingredients inherent to many of the most effective behavioral change campaigns: social influence, social norms and vivid examples. If only Elvis were still alive to harness social influence, social norms and vivid examples.

The Science of Spiritual Narcissism
Posted in Interesting

Perhaps on the whole, spiritual practices really do help quiet the ego, and spiritual narcissism isn’t that widespread. SELF-CENTRALITY AND SPIRITUALITYIn the past few years, a number of high-quality studies have started to unearth the existence of spiritual narcissism and self-enhancement among spiritual practices that purport to quiet the ego. SPIRITUAL SUPERIORITY AND SPIRITUAL PRACTICESIn a more recent set of studies, Roos Vonk and Anouk Visser conducted an exploration of “spiritual superiority.” They interviewed several psychologists, spiritual trainers and lay people, and asked them to describe people who use spirituality as a self-enhancement tool. Interestingly, their scale of spiritual superiority was more strongly correlated with communal narcissism than self-esteem, providing evidence for the notion of “spiritual narcissism.” Indeed, it’s important to distinguish between healthy self-esteem and narcissism. Increases in healthy self-esteem as a result of spiritual practices may be a good thing, and are not necessarily indicative of spiritual narcissism, which is why it’s good that the researchers were able to tie their measure of spiritual superiority to a specific form of narcissism: communal narcissism.

The Eyes Have It: Scientists 3-D Print Human Corneas
Posted in Interesting

3-D printing of human corneas may end wait times for people on transplant waiting lists. 3-D printing is a manufacturing process that creates a physical object from a digital design. Now, according to a paper published online on May 30, 2018 in the journal Experimental Eye Research, scientists are using 3-D printers to make human corneas — an advancement that could dramatically ease the shortage of corneas from donors. However, this promising 3-D printing technique may help people see better without the prolonged wait. That's where this new 3-D printing technique comes into play.

A Step to Ease the Pandemic Mental Health Crisis
Posted in Interesting

For months a mental health crisis has accompanied the misery brought on by COVID-19. Meanwhile mental health services have been stretched worldwide. One reason is that mental health personnel and the facilities they work in have been reassigned to COVID-related tasks during the crisis. These techniques allow people to become mental health first responders. Mental health first aid is slightly different from psychological first aid because it is targeted at people experiencing issues even before a crisis erupts.

Can Shocking Images Persuade Doubters of COVID’s Dangers?
Posted in Interesting

Images are visceral reminders of the pandemic’s dangers, revealing unsettling events behind closed doors, showing us suffering’s human face. Is there evidence showing that shocking images reliably persuade? In our study, we found that participants also believed shocking images would deliver a persuasive punch, moving people’s attitudes about the risks of the coronavirus. Viewing disturbing images, we use the sadness or outrage we ourselves feel as a guide to understand how others will feel. If you entered our study doubting the threat, the images didn’t shock you and, accordingly, didn’t move your thinking.

Another Way to Protect against COVID beyond Masking and Social Distancing

Estimated virus half-life was more than 24 hours at 10 degrees C (50 degrees F) and 40 percent relative humidity, but only 90 minutes at 27 degrees C (80 degrees F) and 65 percent relative humidity. Indeed, a study conducted in New South Wales, Australia, demonstrates an inverse relationship between relative humidity and transmission of SARS-CoV-2. We are requesting that the WHO produce clear guidelines on the minimum lower limit of air humidity in buildings. We recommend maintaining relative humidity between 40 to 60 percent to maximize the benefits of humidity but not the drawbacks of too much humidity that promote mold growth. Indoor air control is the next frontier to improve human health and reduce transmission of various types of viruses, including SARS-COV-2.

Forever Chemicals Are Widespread in U.S. Drinking Water

“We're also being exposed to many more PFASs via the drinking water,” Wang says. Higgins notes that people are also exposed to the compounds in substances besides drinking water, such as household products and food. “Aggressively addressing PFAS in drinking water continues to be an active and ongoing priority for the EPA,” an EPA spokesperson wrote to Scientific American. “The agency has taken significant steps to monitor for PFAS in drinking water and is following the process provided under the Safe Drinking Water Act to address these chemicals.”Technologies to remove PFASs from drinking water exist on both household and municipal levels. Some states have instituted or proposed limits on PFASs in drinking water, but experts say federal action is needed to tackle such a widespread problem.

New Ruling Cracks Down on Emotional Support Animals on Planes

Richard Atrero de Guzman/Anadolu Agency/Getty ImagesIn a long-awaited ruling, the U.S. Department of Transportation (DOT) announced on Dec. 2, 2020, that \"carriers are not required to recognize emotional support animals as service animals and may treat them as pets.\" This ruling came after a skyrocketing number of pets flying as service and \"emotional support animals\" (ESAs) — up 150 percent between 2015 and 2017, according to Delta — had prompted the airline and others to enact more stringent requirements for on-board animals. \"The research on the positive impact that emotional support animals have on people who are struggling with mental illness is pretty plentiful,\" says psychologist Tanisha Ranger, who works mainly with veterans. Many passengers looking to avoid this fee had started to classify their pets as emotional support animals. And when untrained animals attack innocent bystanders, it further creates stigma for those who actually need service animals.\"

Inside the CIA's Treasure Trove of bin Laden Files
Posted in Interesting

When bin Laden became a wanted man, running from the U.S. government, he began wearing a black cowboy hat when out in public, thinking it would shield his identity from spy satellites and drones. Bin Laden was an intense and religious person, joining the zealous Muslim Brotherhood in high school. Initially, bin Laden denied involvement, but in October 2004, he released a video claiming responsibility and decrying American intervention in the Middle East.

Be Skeptical of Video Showing Vaccine \"Side Effect
Posted in Interesting

Such is the case with a “viral” video showing a woman who claims her symptoms are a side effect of the Moderna vaccine (short answer – they almost certainly are not). But are there any positive signs that indicate a conversion disorder, rather than this only being a diagnosis of exclusions? In any case – if I looked at this video without any context, I would conclude this is overwhelmingly likely to be conversion disorder. Conversion disorder is not “faking” (faking is technically called a factitious disorder, or more colloquially, malingering). This also is a real medical disorder, just a psychological one, and should not be stigmatized.

Did a Supermassive Black Hole Influence the Evolution of Life on Earth?
Posted in Interesting

When gas flows towards the black hole, it swirls like water going down the drain. As the gas approaches a fraction of the speed of light at the innermost stable circular orbit (ISCO) around the black hole, it heats-up by rubbing against itself through turbulent viscosity. The exposure to past XUV flares from SgrA* at closer distances, could have harmed complex life during the early evolution of the Earth. But it is also possible that the black hole, SgrA* played an important role in shaping the history of terrestrial life. If a link between SgrA* and terrestrial life can be established, then this supermassive black hole might trigger a second Nobel Prize.
