Decades of data paint a compelling case for why COVID-19 survivors, even those with few symptoms, could experience long-term effects on the brain and central nervous system.
Working with mice, researchers have identified an immune system cell that they say travels from the gut to the brain and attacks cells rather than protect them as it normally does.
Covid-19 patients who recovered from the disease still have robust immunity from the coronavirus eight months after infection, according to a new study. The result is an encouraging sign that the authors interpret to mean immunity to the virus probably lasts for many years, and it should alleviate fears that the covid-19 vaccine would require repeated booster shots to protect against the disease...
Before the pandemic, one-third of U.S. households with children were already "net worth poor," lacking enough financial resources to sustain their families for three months at a poverty level, finds new research from Duke University.
Beginning his work in marine biology, Randy Wells thought he was a shark guy.
Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.
They are as thin as a hair, only a hundred thousand times thinner—so-called two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They became known to a wider audience when two Russian-British scientists were awarded the Nobel Prize in Physics in 2010 for the discovery of graphene, a building block of graphite. The special feature of such...
For more than seven years, a mysterious wasting disease has nearly killed off sea star populations around the world. Some of these species stand at the brink of extinction.
The main criticism about nuclear fusion has been that its vast potential as a commercial source of energy has always been just out of reach.
The Earth is populated by an increasing number of people who demand more and more products, which is simply not viable in the long run. Our planet does not have unlimited resources. Emissions are harming the environment in various ways.
Using copper foil, glass containers and a conventional household microwave oven, University of Wyoming researchers have demonstrated that pulverized coal powder can be converted into higher-value nano-graphite.
Companies in the petroleum and other industries will not be held legally responsible for killing migratory birds as long as they did not mean to, the Trump administration said Tuesday, drawing swift condemnation from animal welfare and conservation groups.
Roughly two billion years ago, microorganisms called cyanobacteria fundamentally transformed the globe. Researchers are now stepping back to that pivotal moment in Earth's history.
New research reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae -- including key features that both collect energy and block excess light absorption. Scientists built a model of the large protein complex called phycobilisome that collects and transmits light energy. Phycobilisomes allow cyanobacteria to take advantage of different wavelengths of light...
The findings, based on analyses of blood samples from 188 COVID-19 patients, suggest that responses to the novel coronavirus, SARS-CoV-2, from all major players in the 'adaptive' immune system, which learns to fight specific pathogens, can last for at least eight months after the onset of symptoms from the initial infection.
Drug-resistant bacteria could lead to more deaths than cancer by 2050, according to a report commissioned by the United Kingdom in 2014 and jointly supported by the U.K. government and the Wellcome Trust. In an effort to reduce the potential infection-caused 10 million deaths worldwide, Penn State researcher Scott Medina has developed a peptide, or small protein, that can target a specific...
E. coli food poisoning is one of the worst food poisonings, causing bloody diarrhea and kidney damage. But all the carnage might be just an unintended side effect, report researchers. Their findings might lead to more effective treatments for this potentially deadly disease.
Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes. Now, an international team of researchers led by University of Copenhagen has conducted a unique mapping of the platypus genome and...
A first-of-its-kind study conducted under the bed of the Dead Sea reveals that a devastating earthquake measuring 6.5 on the Richter scale is expected to hit the region in the coming years. The study showed that an earthquake of this magnitude occurs in the land of Israel on an average cycle of between 130 and 150 years, but there have been cases in history where the lull between one earthquake...
Chinese scientists have established the world's first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a total distance of 4,600 kilometers for users across the country. The team, led by Jianwei Pan, Yuao Chen, Chengzhi Peng from the University of Science and Technology of China in...
Investing in biotech companies may not entail higher risk than investing in other sectors, according to a new report from Bentley University's Center for Integration of Science and Industry. A large scale study of biotechnology companies that completed Initial Public Offerings (IPOs) from 1997-2016 demonstrates that these companies produced more than $100 billion in shareholder value and almost...
The distribution and concentration of dissolved oxygen and water temperature in the oceans and freshwaters are usually far more influential in shaping the growth and reproduction of fish than the distribution of their prey.
Photosynthetic organisms tap light for fuel, but sometimes there's too much of a good thing.
Step into your new, microscopic time machine. Scientists at the University of Colorado Boulder have discovered that a type of single-celled organism living in modern-day oceans may have a lot in common with life forms that existed billions of years ago—and that fundamentally transformed the planet.
A new government report says gas mileage for new vehicles dropped and pollution increased in model year 2019 for the first time in five years.
Cell biologists have found a key clue in the mystery of how chromosomes are inherited correctly every time a cell divides. Using a novel cell probe, they unraveled how a 'matchmaker' molecule stops cell division until components are ready to be split. Precise chromosome duplication is a key factor in proper cell division. If components are altered, even slightly, birth defects and certain cancers...
Two-dimensional materials, consisting of a single layer of atoms, have been booming in research for years. They possess novel properties that can only be explained with the help of the laws of quantum mechanics. Researchers have now used ultracold atoms to gain new insights into previously unknown quantum phenomena. They found out that the magnetic orders between two coupled thin films of atoms...
Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy.
A new class of protein material that interacts with living cells without being absorbed by them can influence cell signaling, a new study shows. The material does this by binding and sequestering cell surface receptors. The discovery could have far-reaching implications for stem cell research and enable the development of new materials designed to modulate the behavior of living systems.
Researchers fabricated regular arrays of iron-coated silicon crystals that are atomically smooth. The defect-free pyramidal composition of the crystals impart magnetic properties that will enhance the functionality of 3D spintronics and other technologies.

Now, an international team of researchers has conducted a unique mapping of the platypus genome and found answers regarding the...
The main bioactive compound of ginger root lowers autoantibody production and helps halt disease progression in mice with antiphospholipid syndrome and lupus.
Researchers found that so-called photonic processors, with which data is processed by means of light, can process information very much more rapidly and in parallel than electronic chips.
Conductive ink is a great tool for printing flexible electronic circuits on surfaces. But these inks can be costly, they do not work on some materials, and devices to apply them can plug up. Now, scientists report that they have developed inexpensive conductive inks for clog-free ballpoint pens that can allow users to 'write' circuits almost anywhere -- even on human skin.
Researchers created an environment in a microwave oven to successfully convert raw coal powder into nano-graphite, which is used as a lubricant and in items ranging from fire extinguishers to lithium ion batteries.
Hoppy beers such as pale ales are becoming increasingly popular. One reason is their pleasant fruity aroma that partially stems from compounds called thiols. Brewers have been looking for an accurate way to track thiols in beer, but current methods typically are not sensitive enough or require use of potentially harmful substances. Now, researchers present an automated, solvent-less process to...
New research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress - literally 'drowning' in their own environment - as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe.
