Allotropy: Why Winter Spells Trouble for the Tin Man
Posted in Strange

Tin is a commonplace metal that’s used industrially in a thousand different ways. From the solder that holds your computer’s motherboard together to the PVC plumbing under your sink, tin compounds are everywhere. This phenomenon, known as “tin pest”, is certainly not due a biological organism, but is widely mistaken for an oxidation reaction. Instead, tin pest happens thanks to something called allotropy—the metal’s atomic lattice can take on multiple different shapes, depending on the temperature it’s kept at. At room temperature, tin exists in its “beta” form.

Scientists Search for Rudolph's Red Nose, and other great stories.
Posted in Strange

Green light (530nm) is readily absorbed by both oxygenated and deoxygenated blood but bounces (scatters) off of the surrounding tissue. Shining green light inside the nose of reindeer and humans, the researchers were able to take detailed videos of the nasal circulatory system, tracking the rate of blood flow through individual blood vessels.The researchers wrote their own image analysis software that can determine the density of blood vessels and track velocity of red blood cells through the dense network of blood vessels.Despite the tongue-in-cheek premise of this study, researchers have not previously used this imaging technique to study nasal circulation. The team found that humans and reindeer noses both feature hairpin-shaped blood vessels and similar capillary networks. Most pertinent to their aim, they found that the density of blood vessels in reindeer noses is 25% greater than the density in human noses, leading to a rosy tint. \"These factors explain why the nose of Rudolph, the lead flying reindeer employed by Santa Claus to pull his sleigh, is red and well adapted to carrying out his duties in extreme temperatures,\" the authors conclude in their paper.The annual BMJ holiday issue is a great read-- check out other great findings from the holiday issues including: whether 27 is actually the dangerous age for musicians, how fast you have to walk to beat Grim Reaper , and the dreamed-of expose on tooth fairy malpractice.

Dire Wolves Were Not Really Wolves, New Genetic Clues Reveal
Posted in Best

It had long been assumed that dire wolves made themselves at home in North America before gray wolves followed them across the Bering Land Bridge from Eurasia. For decades, paleontologists have remarked on how similar the bones of dire wolves and gray wolves are. Dire wolves, it now appeared, had evolved in the Americas and had no close kinship with the gray wolves from Eurasia; the last time gray wolves and dire wolves shared a common ancestor was about 5.7 million years ago. Perri, Mitchell and their colleagues found no DNA evidence of interbreeding between dire wolves and gray wolves or coyotes. Dire wolves were genetically isolated from other canids, Mitchell notes, so “hybridization couldn’t provide a way out” because dire wolves were probably unable to produce viable offspring with the recently arrived wolves from Eurasia.

Biden Names Top Geneticist Eric Lander as Science Adviser
Posted in Strange

US president-elect Joe Biden has chosen decorated geneticist Eric Lander as presidential science adviser and director of the Office of Science and Technology Policy (OSTP). Many scientists have long called for the OSTP director to be raised to a cabinet-level position. When Biden named Lander to his team on 15 January, he also announced a number of other respected scientists to key positions in his administration. One major question is what parts of science policy Lander and his office will be responsible for. The outgoing OSTP director, meteorologist Kelvin Droegemeier, wasn’t appointed by President Donald Trump until more than a year and a half into his administration.

Fighting Ice With...Ice?
Posted in Strange

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.

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

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.

How the Suburbs Could Help Save Biodiversity
Posted in Insane

This past summer saw at least tens of thousands of migrating birds drop dead from the sky over the Southwest. Too many of the exotic plants sold in nurseries are essentially inedible to most native animals. Yes, you’re saving water over planting thirsty ornamentals or a lawn, but drought-tolerant exotic plants can become invasive disasters when they escape our yards. Even in drier areas, like the American West, the selection of attractive native plants to choose from is vast. For those disenchanted with dry landscaping, using underappreciated and lush water-loving native plants to make your garden a real-life oasis could lifesaving to wildlife.

The Timeless Journey of the Möbius Strip
Posted in Cool

If you were to trace both “sides” of a Möbius strip, you would never have to lift your finger. The figurative and narrative implications of the Möbius strip are rich: when you try to go forward, you ring sideways, when you try to circle in, you find yourself outside. The continuum of crossing a Möbius strip is emblematic of how we experience time in a nonlinear way. ‘Time passes.’ ‘That’s how it goes,’ Aureliano admitted, ‘but not so much.’”The unorientable quality of the Möbius strip is perhaps its most distinctive. The Möbius band is used in hardware and popular imagery, but the mathematical and scientific fascination with the Möbius strip has also endured for over a century.

People “should not really consider themselves protected until after a week or two following dose two,” he adds. The researchers now are studying whether outcomes vary for people on specific types of these drugs, the release states. Experts call this a One Health approach or concept, and they want governments to factor it into policies, Robbins reports. As humans move into more of Earth’s natural environments, more spillovers of animal diseases into humans are expected. “The spillover of animal, or zoonotic, viruses into humans causes some 75% of emerging infectious diseases,” Robbins writes.

Holiday Instability
Posted in Insane

The reason Christmas trees topple so easily is because their base is so small. Anything making small contact with the ground relative to its size is going to be fairly unstable. It only has to be pushed past its edge of contact with the ground before it starts to tip over. Likewise, an object will tip over more slowly when it's center of mass is further away from the pivot point. That means the menorah, with the higher center of mass, will be easiest to control and easiest to juggle.

The ‘Shared Psychosis’ of Donald Trump and His Loyalists
Posted in Strange

The violent insurrection at the U.S. Capitol Building last week, incited by President Donald Trump, serves as the grimmest moment in one of the darkest chapters in the nation’s history. One such person is Bandy X. Lee, a forensic psychiatrist and president of the World Mental Health Coalition. Expert on the psychology of Donald Trump and his supporters says their behavior can be explained by a “narcissistic symbiosis” and “shared psychosis.” Tayfun Coskun Getty ImagesDo you think Trump is truly exhibiting delusional or psychotic behavior? And (3) fixing the socioeconomic conditions that give rise to poor collective mental health in the first place. And the situation with Trump supporters is very similar.

Did We Receive a Message from a Planet Orbiting the Nearest Star?
Posted in Insane

This infrared star hosts an Earth-size planet, Proxima b, in its habitable zone, where liquid water could allow the chemistry of life on the planet’s surface. But even without examining the event details, one might wonder whether it is plausible for a radio signal to originate from our nearest star system. Following this argument, the quantitative paper with Amir shows that the chance of a radio signal appearing now from our nearest star is miniscule. There is one caveat to this conclusion, namely if intelligent life on Earth and its nearest star are correlated. Interestingly, Proxima Centauri became our nearest star around the same time when Homo sapiens appeared on Earth.

Unrivaled View of Brilliant ‘Planetary Nebula’ NGC 2899
Posted in Interesting

A star at the center of this tie-dye apparition is collapsing, a process scientists have watched and measured for decades. In 2020 astronomers overcame the 3,000 to 6,500 light-years separating us from this celestial beauty, named NGC 2899, for the clearest picture of it yet. Though the phenomenon is called a planetary nebula, the term is a misnomer. In the image of NGC 2899, oxygen (blue) is surrounded by hydrogen (pink). Discovered in 1835 by English astronomer John Herschel in the constellation Vela, NGC 2899 looks like a butterfly because it is made of two stars.

Vaccines Need Not Completely Stop COVID Transmission to Curb the Pandemic
Posted in Strange

According to Dawn Bowdish, a professor of pathology and molecular medicine at McMaster University, this so-called sterilizing immunity was a key factor in eliminating smallpox. “The [smallpox] vaccination caused sterilizing immunity, meaning that you don’t carry any of the virus. Sterilizing immunity may have been a lofty goal for COVID-19 vaccine manufacturers, though not necessary to curb disease. The oral polio vaccine (OPV) generates localized intestinal immunity, preventing infection and protecting against disease and transmission. But ample precedent points to vaccines driving successful containment of infectious diseases even when they do not provide perfectly sterilizing immunity.

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

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 Science Explains Trump’s Grip on White Males
Posted in Insane

Slovic and his team found that White males differed from White women and non-White men and women in how they perceived risks. For every category of threat, White men saw risk as much smaller and much more acceptable than did other demographic groups. And in the case of White men, it is often a lens that seeks to preserve institutionalized cultural identity and societal status. And it’s not hard to imagine why the term “White male effect” would struggle to gain traction in a media landscape dominated by White men. Virtuous violence is still violence and there is nothing abstract about identity protective cognition’s role in White male supremacy.

For Black and Brown Kidney Patients, There Are Higher Hurdles to Care
Posted in Insane

The international actuarial and consulting firm Milliman estimates that the average billable cost for a kidney transplant in 2020 is $442,500. Both Black and Hispanic patients were less likely to receive this care compared to White patients. Indeed, according to an analysis of data from 1990 to 2009, Black patients waited an average of 2.5 months longer than White patients for a kidney transplant. Despite such changes in organ donation, Black patients on dialysis are still far less likely than White patients to receive a living donor kidney. Black patients, then, tend to reach out to fellow Black family and friends.

Kidney Dialysis Is a Booming Business—Is It Also a Rigged One?

What's more, both are widely known to donate hundreds of millions of dollars to the American Kidney Fund, covering the vast majority of the nonprofit’s budget. The social worker paused, then asked if she’d heard about the American Kidney Fund. They found fewer kidney transplants, higher rates of hospitalization, and lower rates of overall survival among dialysis patients at for-profit clinics. Records from the California Secretary of State showed that dialysis corporations forked over upwards of $110 million via the California Dialysis Council in 2018. Unlike Karabasz, who blames AB 290 and those behind it for the uncertainty of her position, Carroll says some responsibility falls on the American Kidney Fund.
