A new method allows the creation of compartments within a liquid that do not have physical barriers. The method could help researchers understand how human cells use 'membraneless compartments' to segregate and concentrate components for important cellular processes, chemical reactions, or other biological functions.

An analysis of public genome sequence data from SARS-CoV-2 and related viruses found no evidence that the virus was made in a laboratory or otherwise engineered.

A new study calculates that the median incubation period for COVID-19 is just over 5 days and that 97.5% of people who develop symptoms will do so within 11.5 days of infection.

A symbol of life, ancient sundial or just firewood? Tree-ring scientists trace the origin of a tree log unearthed almost a century ago.

Many people dream of comfortably living out their golden years. A new study however shows that older Europeans, and especially women, frequently underestimate how many years they have left, which could lead to costly decisions related to planning for their remaining life course.

Botulinum toxin (BoNT) is used for a range of applications, but when injected it can diffuse into the surrounding tissue and give rise to adverse effects. A new study shows that a subtle modification of an FDA-approved form of BoNT enhances binding to the nerve cells and improves the drug's potency and safety.

Researchers have developed an AI-powered, smart insole that instantly turns any shoe into a portable gait-analysis laboratory.

Research demonstrates that machine learning can predict and avoid damaging disruptions to fusion facilities.

New research finds that the virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces. Scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.

Need to reduce high-pitched noises? Science may have an answer. Theoretical physicists report that materials made from tapered chains of spherical beads could help dampen sounds that lie at the upper range of human hearing or just beyond.

Researchers have found that much of the current emission of these gases likely stems from large CFC 'banks' -- old equipment such as building insulation foam, refrigerators and cooling systems, and foam insulation, that was manufactured before the global phaseout of CFCs and is still leaking the gases into the atmosphere. Based on earlier analyses, scientists concluded that CFC banks would be too...

Scientists discover the structure of an enzyme, found in the human gut, that breaks down a component of collagen.

Growing fruit and vegetables in just 10 per cent of a city's gardens and other urban green spaces could provide 15 per cent of the local population with their 'five a day', according to new research.

In the production of chemical compounds, the success of each individual reaction depends on numerous parameters. It is not always possible, even for experienced chemists, to predict whether a reaction will take place and how well it will work. In order to remedy this situation, chemists and computer scientists have now developed a tool based on artificial intelligence.

Fifty years ago, researchers placed a mystery worm in a 'wastebasket' genus and interest in the lowly critter waned -- until now.

The crystal structure at the surface of semiconductor materials can make them behave like metals and even like superconductors, a research team has shown. The discovery potentially opens the door to advances like more energy-efficient electronic devices.

Permafrost soils in the Arctic are thawing. In Russia, experiments are now being conducted in which herds of horses, bison and reindeer are being used to combat this effect. A study shows for the first time that this method could significantly slow the loss of permafrost soils. Theoretically speaking, 80 percent of all permafrost soils around the globe could be preserved until the year 2100.

High-resolution micro-CT scanning of the skull of the fossil specimen known as 'Little Foot' has revealed some aspects of how this Australopithecus species used to live more than 3 million years ago.

Researchers were able to test blood samples at four different time points in an otherwise healthy woman in her 40s, who presented with COVID-19 and had mild-to-moderate symptoms requiring hospital admission.
