While testing the quality of water near Greenland, researchers discovered unusually large amounts of toxic mercury that was released from melting ice glaciers. They are speculating about the consequences on sea food quality and how to manage the levels of mercury.
Study of life in Earth's subsurface revealed that it's possible for microbial life to exist deep underground. These microbes get energy from water molecules being split by unstable rock atoms creating energy as replacement for Sun's energy and other remaining products that are able to sustain life. Based on this, scientists predict that life on other rocky planets in their subsurface is possible, if there is water.
Study in London used six enthusiastic dogs in a double-blind trial Coronavirus – latest updates See all our coronavirus coverage Faster than PCR and more accurate than lateral flow tests, the latest weapons against Covid-19 have four legs and a wet nose. A study published on Monday found that people who are infected with coronavirus give off a distinct odour, which these highly trained dogs can d
Even when our most basic civilizational values are in dispute, there are a few sets of rules and regulations that we nevertheless manage to share. The laws of the sea, for example, or the norms governing the conduct of air-traffic controllers. Pilots of any nationality, even when flying to Caracas, Havana, or Pyongyang, have no reason to believe that the instructions they receive from the ground
R ereading Exodus , the schmaltzy 1958 best seller about Israel that became a Hollywood movie starring Paul Newman, I was surprised by something I hadn't noticed as a teenager. The author, Leon Uris, describes a utopia of brave young pioneers in khaki shorts, farming when possible and fighting when necessary, quoting Bible verses as they hook up in ancient ruins, and so forth. But the novel isn't
If you've followed recent Democratic messaging, you'll have heard that American democracy is under serious attack by the Republican Party, representing an existential threat to the country. If you've followed Democratic lawmaking, you'd be forgiven for thinking that the threat is actually a rather piddling one. The disconnect, in this case, isn't attributable to Democratic embellishment, but to i
The 58-year-old man was blind, barely able to perceive whether it was day or night. After receiving gene therapy to add light-sensing molecules to one of his retinas, he could locate a notebook set on a table. Scientists in Europe and the US are reporting today what they describe as the first successful use of optogenetics to improve a person's vision. The feat involved introducing a gene from al
On January 11, antivirus company Bitdefender said it was "happy to announce" a startling breakthrough. It had found a flaw in the ransomware that a gang known as DarkSide was using to freeze computer networks of dozens of businesses in the US and Europe. Companies facing demands from DarkSide could download a free tool from Bitdefender and avoid paying millions of dollars in ransom to the hackers

Although the full supermoon will be easily seen from Europe and Africa, sadly the eclipse will not be The moon will be full on 26 May. This will coincide with the largest supermoon of the year, and also the first total lunar eclipse since January 2019. Although precise definitions vary, a supermoon is said to occur when the full moon takes place near the closest point in its orbit to the Earth. T
Needs Pepper A team of NASA researchers suspect that they've made a huge discovery about Mars: traces of organic salts on the surface. If that's true — the scientists haven't completely ruled out other compounds yet — then it would lend much more credibility to the hypothesis that Mars once supported life . These salts, according to research published in the Journal of Geophysical Research: Plane
Countries around the world are beginning to reckon with a years-long drop in new births that has skewed population demographics heavily toward older age groups. Thanks to that near-global drop in fertility rates, experts suggest that the planet's population could enter a period of continued decline for the first time in known human history by the second half of the 21st century, The New York Time
A previously-undisclosed US intelligence report reveals that multiple researchers at the Wuhan Institute of Virology became sick and went to the hospital right around the time that COVID-19 is thought to have started circulating in China. The report specified that three researchers from the lab were hospitalized in November 2019 "with symptoms consistent with both COVID-19 and common seasonal ill
Scans show some brains have a stronger link between the part that processes sound and that which controls the mouth and throat Scientists have shed light on why everyday sounds such as chewing, drinking and breathing can be so maddening to some people that it drives them to despair. While the familiar munching and slurping of the dinner table are innocuous enough to most, those with misophonia –
The three teenagers—two boys and a girl—could not have known what clues their lungs would one day yield. All they could have known, or felt, before they died in Germany in 1918 was their flu-ravaged lungs failing them, each breath getting harder and harder. Tens of millions of people like them died in the flu pandemic of 1918; they happened to be three whose lungs were preserved by a farsighted p
The Tulsa Race Massacre of 1921 was over in less than 24 hours, but the damage that the city's Black citizens suffered went on for decades. Indeed, the full magnitude of the community's economic loss is still coming into focus even on the centennial of the event —in part because new digital tools allow scholars to mine census records for data about its aftermath. On May 31, 1921, a mob of more th

In recent years, rapid advance s in both robotics and neural interfaces have brought the dream of bionic limbs ( like the one sported by Luke Sky
One of the fundamental themes in astrobiology is to seek to ascertain the origin and distribution of life in the cosmos. As part of this, the field also deals with how life may be transferred from one planetary system to another. Recent research may give insight into how we could detect traces of this intriguing process in the future.
At the heart of some of the smallest and densest stars in the universe lies nuclear matter that might exist in never-before-observed exotic phases. Neutron stars, which form when the cores of massive stars collapse in a luminous supernova explosion, are thought to contain matter at energies greater than what can be achieved in particle accelerator experiments, such as the ones at the Large Hadron
Vertical farming leverages cutting-edge technology to grow food in a new and better way. One of its many benefits is that it can increase crop yield by 700 percent. Vertical farming can help relieve pressure on scarce resources and boost Earth's biodiversity. One day soon, you could eat bananas grown in downtown Manhattan. It's a way of growing food that turns traditional agriculture on its head.
Republicans aren't exactly pumping out fresh policy innovations these days. If anything motivates congressional Republicans, it's retaking the majority in 2022 and placating the put-upon ex-president Donald Trump.

Since the mid-2000s, Branson's Virgin Galactic has been inching toward high-altitude spaceplane flights that will offer a few minutes of weightlessness. Fellow billionaires Elon Musk and Jeff Bezos have more recently gotten into commercial rockets that have the potential to take passengers into space. Regardless, Brans
Philosopher Robert Nozick asked if we would rather live in the real world or inside a virtual reality machine of never-ending pleasure. Frederich Nietzsche asked if truth is really the greatest virtue. People seem to be hard-wired to want the truth, no matter how brutal or unpleasant. The year is 2045, and an eccentric billionaire has revealed to the world an incredible new invention. It's called
Regular physical activity has positive effects on children's developing brain circuits, finds a Boston Children's Hospital study using neuroimaging data from nearly 6,000 early adolescents. Physical activity of any kind was associated with more efficiently organized, flexible, and robust brain networks, the researchers found. The more physical activity, the more "fit" the brain.

Scientists report that it is possible to detect and predict heat damage in crops by measuring the fluorescent light signature of plant leaves experiencing heat stress. If collected via satellite, this fluorescent signal could support widespread monitoring of growth and crop yield under the heat stress of climate change, the researchers say.
Fifty-six million years ago, as the Earth's climate warmed by five to eight degrees C, new land mammals evolved, tropical forests expanded, giant insects and reptiles appeared and the chemistry of the ocean changed. Through it all, bacteria in the ocean in what is now New Jersey kept a record of the changes in their environment through forming tiny magnetic particles. Now, those particles and thei
Carbon is vital to the existence of all living organisms, since it forms the basis of all organic molecules that, in turn, form the basis of all living beings. While that alone is pretty impressive, it has recently found surprisingly novel applications in disciplines such as aerospace and civil engineering with the development of carbon fibers that are stronger, stiffer, and lighter than steel. Co

A study of 1,095 patients hospitalized with COVID-19 found that two easily measured signs of health – respiration rate and blood-oxygen saturation – predict higher mortality.

GPT-3/DALL-E and similar stuff look amazing in the demos, truly revolutionary, and yet all the applications that are popping are either closed betas, or seem a bit gimmicky or proof of concept at most.

The study shows that a diet high in sugar and fat causes damage to Paneth cells, immune cells in the gut that help keep inflammation in check. When Paneth cells aren't functioning properly, the gut immune system is excessi
