Tesla CEO Elon Musk isn't afraid of Anonymous — or, at least, of folks on the internet who claim to be associated with the hacktivist organization Anonymous. Over the weekend, an account that claimed to be associated with the group uploaded a video to social media that accused the billionaire of destroying lives by playing the crypto markets. "You may think that you are the smartest person in the

The New York Times is having a strange day. This afternoon, the prominent newspaper published an article making a surprising claim about exobiology: that watermelons had been discovered on Mars. "Authorities say rise of fruit aliens is to blame for glut of outer space watermelons," read the story, which was deleted less than an hour later, according to a partial cache of its contents on Google Ne
According to Internal Revenue Service data obtained by ProPublica , some of the wealthiest people in the world have paid extremely little in federal income taxes in recent years. In fact, several billionaires managed to whittle down their federal income tax return to zero dollars. Tesla CEO Elon Musk managed to do so in 2018. Amazon CEO Jeff Bezos, now the world's richest man, paid zero dollars i

During a pandemic , no one's health is fully in their own hands. No field should understand that more deeply than public health, a discipline distinct from medicine. Whereas doctors and nurses treat sick individuals in front of them, public-health practitioners work to prevent sickness in entire populations. They are expected to think big. They know that infectious diseases are always collective
A team of researchers from Oklahoma State University, the University of Central Oklahoma and the University of Arkansas has found that the mere sight of sick birds of their own kind is enough to set off an immune response in healthy canaries. In their paper published in the journal Biology Letters, the group describes experiments they conducted with caged birds in their lab.
The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the earliest days of the solar system. But new University of Arizona-led research suggests that the asteroid might not be as metallic or dense as once thought, and hints at a much different origin story.

Extra Dimension According to a team of researchers at the University of California, Riverside, an extra dimension in space-time could be hiding dark mater — the stuff that appears to make up 85 percent of the mass in the universe, yet remains undetectable by scientific equipment. "We live in an ocean of dark matter, yet we know very little about what it could be," said Flip Tanedo, assistant prof
To survive in the frigid ocean waters around the Arctic and Antarctica, marine life evolved many defenses against the lethal cold. One common adaptation is the ability to make antifreezing proteins (AFPs) that prevent ice crystals from growing in blood, tissues and cells. It's a solution that has evolved repeatedly and independently, not just in fish but in plants, fungi and bacteria. It isn't…
My Atlantic colleague John McWhorter and I must have received the same high-frequency language-nerd alert, audible only to the types of people whose idea of fun is Esperanto grammar.

Carl Schoonover and Andrew Fink are confused. As neuroscientists, they know that the brain must be flexible but not too flexible. It must rewire itself in the face of new experiences, but must also consistently represent the features of the external world. How? The relatively simple explanation found in neuroscience textbooks is that specific groups of neurons reliably fire when their owner smell
Science can allow us to determine what happened trillionths of a second after the Big Bang. But it likely never will be possible to know what brought about the Big Bang. As frustrating as it might be, some things are entirely unknowable. And that's a good thing. Let's face it: to think that the universe has a history that started with a kind of birthday some 13.8 billion years ago is weird. It re

People often ask me whether human-level artificial intelligence will eventually become conscious. My response is: Do you want it to be conscious? I think it is largely up to us whether our machines will wake up. That may sound presumptuous. The mechanisms of consciousness—the reasons we have a vivid and direct experience of the world and of the self—are an unsolved mystery in neuroscience, and so
The boy was only a month old but had developed the amount of health problems that other people don't acquire in a lifetime.

He shared the news this week on Instagram
Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a 'stable' pair known as a diquark. It seems, however, that it's the end of the road for the diquarks in physics. This is one of the conclusions of the new model of proton-proton or proton-nucleus collisions, which takes into account the interactions of gluons with the s

Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23634-7 Reflective surfaces have been recommended to mitigate urban heat pollution but can be expensive to apply at a large scale. This work shows that applying them to only the upstream half of a neighborhood can lead to disporportionately high cooling benefits relative to cost.
Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23579-x Regular exercise promotes overall health and prevents non-communicable diseases, but the adaptation mechanisms are unclear. Here, the authors perform a meta-analysis to reveal time-specific patterns of the acute and long-term exercise response in human skeletal muscle, and identify sex- and age-specific changes.
Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23760-2 Antiferromagnets (AFM) exhibit faster magnetization dynamics, and have immunity to stray fields, making AFMs attractive for spintronic devices. Here, the authors investigate the behaviour of domain walls in AFMs, and find a new type domain wall, a superposition of two adjacent rotational domains.
Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23680-1 Cyanobacterial thylakoid membranes host the molecular machinery for the light-dependent reactions of photosynthesis and respiratory electron flow. Here, the authors show that newly synthesized thylakoids emerge between the plasma membrane and pre-existing thylakoids and describe the time-dependent assembly proce
Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23694-9 Working memory requires the brain to switch between cognitive states and activity patterns. Here, the authors show that the steering of these neural network dynamics is influenced by dopamine D1- and D2-receptor function and altered in schizophrenia.
Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23845-y Domain wall skyrmions have been proposed but the experimental observation has been difficult.

Nature Communications, Published online: 09 June 2021; doi:10.1038/s41467-021-23621-y Some patients with COVID-19 fail to clear the viral infection quickly, yet our understanding for the underlying immune characteristics is still lacking. Here the authors use single-cell RNA sequencing and other data form such patients to show that persistent infection is associated with immune suppression and re
Nearly 30% of adults with a history of heart attack, heart failure, stroke or other cardiovascular disease reported ongoing use of cigarettes or other tobacco products at the start of a large, nationally representative study spanning 2013-2018.At the end of the five-year study, approximately one in five of the study participants was still smoking.Cigarettes were the tobacco product used most often
Proponents of tratamento precoce, or "early treatment" — which include Brazil's President Jair Bolsonaro — lean on discredited or skewed experiments to trumpet the regimen's effectiveness, even after several of the pills were proven to not work against Covid-19 in conclusive clinical trials last year.
Early on the morning of October 12, 2020, 27-year-old Jang Deok-joon came home after working his overnight shift at South Korean e-commerce giant Coupang and jumped into the shower. He had worked at the company's warehouse in the southern city of Daegu for a little over a year, hauling crates full of items ready to be shipped to delivery hubs. When he didn't come out of the bathroom for over an h
A lab leak theory of the COVID-19 origins has enough circumstantial evidence and historical basis to support the urgent need for an independent and unbiased investigation. But until recently, scientists dismissed lab leak as a conspiracy theory. In public at least.
PLUS. Ingeniørforeningen IDA lægger med sin nye klimaplan op til, at cyklisme og kollektiv trafik skal løfte en større del af danskernes mobilitetsbehov i fremtiden. Det vil kræve en omlægning af bilbeskatning til kørselsafgifter. Forskere er enige om, at kørselsafgifter er svære at komme udenom.

Why did the deer cross the road? According to research from the University of New Hampshire to keep going and going and going. Researchers have discovered the longest distance ever recorded by an adult male white-tailed deer—300 kilometers, or close to 200 miles, in just over three weeks. The finding has important implications for population management and the transmission of disease, especially c
During spring, Lusitanian toadfish (Halobatrachus didactylus) suitors form choirs in Portugal's Tagus estuary to serenade the females, vibrating their swim bladders to produce a call, known as a boatwhistle, which sounds like a vibrating cell phone. The males also listen in on each other to check whether anyone is intruding on their territory. But sadly, their performances are no longer conducted
the cost of building rail from say L.A. to new york would be astronomical, along with the amount of time such a thing would take. the problem of eminent domain comes into play because it could cause tons of hefty legal battles, because people either refuse to sell their land for a certain price, or just refuse to sell it at all. and thats just from one place to another, to have a vast network spa
The oxide dispersion strengthened copper alloy (ODS-Cu) is superior in thermal conductivity, electrical conductivity and heat resistance. Although the ODS-Cu can be expected to have various industrial applications, its joint with other materials is extremely difficult because of its intrinsic poor weldability. The research group has developed an extremely novel joint technique that enables us to f

Researchers found monarchs raised in captivity can successfully migrate if given time to orient themselves. They discovered this by equipping the butterflies with tiny radio transmitters and monitoring them for 200 km, debunking previous research that found the butterflies couldn't orient themselves. Monarchs released into the wild flew in the proper direction because they were exposed to natural
Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area.
