The James Webb Space Telescope team has fully deployed the spacecraft's 70-foot sunshield, a key milestone in preparing it for science operations.

Physicists have directly observed ultracold atoms forming 'quantum tornadoes' in a spinning fluid of ultracold atoms. The observations record a key crossover from classical to quantum behavior.

We can now tell the difference between a wide range of plastic types and thereby separate plastics according to their chemical composition. This is absolutely ground-breaking and it will increase the rate of recycling of plastics immensely. The technology has already been tested at pilot scale and it will be implemented at an industrial scale in spring 2022.

An international team has made a significant breakthrough in understanding why Alzheimer's disease progresses so rapidly in some people that they die within three years. The researchers found a link between strains of misshapen and fast-replicating tau protein and accelerated cognitive decline -- a critical result that illuminates the variations in Alzheimer's disease and could help lead to more...

Standard chemotherapies may efficiently kill cancer cells, but they also pose significant risks to healthy cells, resulting in secondary illness and a diminished quality of life for patients. To prevent the previously unavoidable damage, researchers have developed a new class of nanomaterials engineered to capture chemotherapy drugs before they interact with healthy tissue.

A new software tool can accelerate materials science research by cutting out tedious background research on material properties. Researchers recently debuted propSym, an open-source software on the programming platform MATLAB, to calculate the fundamental constants needed to describe the physical properties of solids, such as metals, ceramics or composites.

A reexamination of Earth's famous 'whiff of oxygen' has the potential to rewrite early accounts of the planet's history by finding that atmospheric oxygen actually did not exist prior to the Great Oxygenation Event (GOE).

Very few proteins in the body have a change that makes them unique compared to the corresponding proteins in Neanderthals and apes. Researchers have now studied one such protein, glutathione reductase, which protects against oxidative stress. They show that the risk for inflammatory bowel disease and vascular disease is increased several times in people carrying the Neanderthal variant.

A new study that mapped the neural connections of newborns with two different kinds of brain injuries found the maps looked very different -- and were linked to significantly different developmental outcomes years later.

Two X chromosomes are actually one too many. Female mammalian cells hence switch off one of them – but only when the cells start to specialize into tissues. A research team has now discovered how cells 'count' their chromosomes and at the same time sense which stage of development they are in.

Dairy farmers in the Northeast -- facing a warming climate that exacerbates nutrient pollution but lengthens the growing season -- can reduce the environmental impact of their operations and maximize revenues by double cropping and injecting manure into the soil, rather than broadcasting it.

A new study has identified a brain circuit that is active while we plan our spoken replies during conversation. The work promises to guide the design of new therapies for the 7.5 million Americans who have trouble using their voices, say the study authors.

Researchers have developed a CRISPR-based assay that can sensitively and non-invasively detect a biomarker of acute kidney rejection in urine. This could someday help diagnose rejection earlier and without a biopsy.

The long-term risks of living in space include bone loss, cosmic radiation and muscle weakness, so leaving gravity behind certainly has its obstacles -- and yet, that doesn't stop people from venturing out of the stratosphere. Some of these potential hurdles have already been studied extensively or are currently being investigated, but researchers have found an important but underserved area of...

A study of pregnant women's blood RNA has found specific molecular profiles that identify women at risk of pre-eclampsia. These insights can identify complications before a woman experiences symptoms.

A new study provides the most comprehensive data ever collected from elite runners with bilateral leg amputations, including the world's fastest 400-meter sprinter, Blake Leeper.

Many experiments show that exposure to LPS during exposure to environmental allergens protects against developing asthma or allergic disease. Yet other numerous experiments show that the presence of LPS during exposure to environmental allergens does the opposite -- it promotes the development of asthma and other allergic disease. Now researchers detail a series of mechanistic steps that reveal a...

New research takes energy efficient windows a step further by proposing a new "smart window" design that would harvest the sun's energy in the winter to warm the house and reflect it in the summer to keep it cool.

As part of an experiment to measure -- to an extremely precise degree -- the charge-to-mass ratios of protons and antiprotons, researchers have found that, within the uncertainty of the experiment, matter and antimatter respond to gravity in the same way.

A new nationwide analysis of 122 plans from 20 US cities found that many plans fail to explicitly define green infrastructure. When they do, they tend to focus on stormwater management, favoring engineered facilities over parks and larger urban green spaces. The study is the first systematic review of the use and definition of the green infrastructure concept in US city plans.

Researchers examined skin regeneration over two years in various body parts of the adult newt, Cynops pyrrhogaster. Their wounds were very quickly healed over several days without prolonged inflammation. Because of this rapid healing, granulation/dermal fibrosis, and therefore scarring, did not occur. The skin was able to fully regenerate. These findings provide evidence that this newt species may...

A trial found that taking a much higher dose of vitamin D than recommended for five years did not affect total mortality or the incidence of cardiovascular disease or cancer in older men and women.

A new study has found 30 per cent of people prefer to talk about their negative experiences with a virtual reality avatar, rather than a person.

The first comprehensive analysis of viral horizontal gene transfer (HGT) illustrates the extent to which viruses pick up genes from their hosts to hone their infection process, while at the same time hosts also co-opt useful viral genes.
