Today's modern cities, from Denver to Dubai, could learn a thing or two from the ancient Pueblo communities that once stretched across the southwestern United States. For starters, the more people live together, the better the living standards.

Astronomers have identified periodic gamma-ray emissions from 11 active galaxies, paving the way for future studies of unconventional galaxies that might harbor two supermassive black holes at their centers.

To find prey in the dark, bats use echolocation. Some species, like Molossus molossus, may also search within hearing distance of their echolocating group members, sharing information about where food patches are located. Social information encoded in their echolocation calls may facilitate this foraging strategy that allows them to find food faster.

Teaching physics to neural networks enables those networks to better adapt to chaos within their environment. The work has implications for improved artificial intelligence (AI) applications ranging from medical diagnostics to automated drone piloting.

A new study found that environmental conditions affect the stability of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human nasal mucus and sputum.

A new report shows that infants under 90 days of age who tested positive for COVID-19 tend to be well, with little or no respiratory involvement. Fever was often found to be the primary or only symptom.

Engineers have devised a model to describe how, in the process of establishing wind farms, interactions between developers and landowners affect energy production costs.

Setting out to identify all proteins that make up the sarcomere, the basic contractile unit of muscle cells, resulted in an unexpected revelation, providing experimental evidence that helps explain a fundamental mystery about how muscles work.

The livelihoods of millions of people living along the world's biggest river systems are under threat by a range of stressors caused by the daily economic, societal and political activity of humans -- in addition to the long-term effects of climate change, researchers report.

A 'smart' system that controls the storage and release of energy from wind turbines will reduce the risk of power cuts and support the increase of wind energy use world-wide, say researchers.

A team of researchers has uncovered new information about the mass of individual components that make up a promising quasiparticle, known as an exciton, that could play a critical role in future applications for quantum computing, improved memory storage, and more efficient energy conversion.

Higher rates of severe COVID-19 infections in Black, Asian and Minority Ethnic (BAME) populations are not explained by socioeconomic or behavioral factors, cardiovascular disease risk, or by vitamin D status, according to new research.

Researchers demonstrate a high level of control over a type of colloid in which the suspended particles take the form of hollow, nanoscale cubes. This case has only previously been explored through theoretical calculations.

Scientists aim to understand how skyrmions behave in a substrate under dc and ac drives.

Researchers are exploring new ways of creating quantum-mechanical interactions between distant electrons. The research marks an important advance in quantum computing.

An 18-year study of 2,000 children born in England and Wales found that young adults raised in communities marked by more economic deprivation, physical dilapidation, social disconnection, and danger display differences in the epigenome -- the proteins and chemical compounds that regulate the activity of their genes. The findings suggest that gene regulation may be one biological pathway through...

Researchers have found that a soy-derived protein fragment that reaches the brain after being ingested reduces memory degradation in mice with an induced cognitive impairment, providing a new lead for the development of functional foods that help prevent mental decline.

Cabbage plants defend themselves against herbivores and pathogens by deploying a defensive mechanism called the mustard oil bomb. Researchers have now been able to show that this defense is also effective against the widespread fungus Sclerotinia sclerotiorum. However, the pathogen uses at least two different detoxification mechanisms that enable the fungus to successfully spread on plants...

A new study of albatrosses has found that wind plays a bigger role in their decision to take flight than previously thought, and due to their differences in body size, males and females differ in their response to wind.

Researchers have developed a pioneering production method for heterostructure devices, based on 2D materials such as graphene.

A research group developed a new technology that can drastically conserve the energy used to capture CO2 from gases exhausted from a concentrated source such as thermal power plants. With this technology, namely H2 stripping regeneration technology, combustion exhaust gas can be replaced by CO2/H2 gas at lower temperatures than those used in conventional technology.

Researchers have observed the exploratory behavior of ants to inform the development of a more efficient mathematical sampling technique.

Differences in the rate that genetic mutations accumulate in healthy young adults could help predict remaining lifespan in both sexes and the remaining years of fertility in women, according to scientists. Their study, believed to be the first of its kind, found that young adults who acquired fewer mutations over time lived about five years longer than those who acquired them more rapidly.

Researchers have shed light on the reproductive role of 'dark matter' DNA - non-coding DNA sequences that previously seemed to have no function. Their findings have revealed that a specific non-coding genomic region is essential for the proper development of the male and female reproductive organs in rice.
