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.

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.

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.

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 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.

A multidisciplinary team of researchers has discovered several genetic markers associated with bone mineral accrual, which could ultimately help identify causes of eventual osteoporosis earlier in life through genetic testing.

Using a blood test, a research team has predicted the risk of Alzheimer's disease in people who were clinically diagnosed as not having Alzheimer's disease but who perceived themselves as cognitively impaired (Subjective Cognitive Declined, SCD). The researchers analyzed blood samples from an SCD cohort. Using a newly developed test, they identified all 22 subjects at study entry who developed...

Vocal learning leads to modification of call structure in a multi-level baboon society.

Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described. A map of brainstem circuits reveals which neurons control the fine motor skills of the arm and hand.

All athletes want to be at the top of their game when they compete, but some resort to nefarious approaches to achieve peak muscle growth, speed and agility. Recent developments in gene editing technology could tempt athletes to change their DNA to get an edge. Now, researchers demonstrate first steps toward detecting this type of doping both in human plasma and in live mice.
