A researcher found that artificial intelligence can accurately detect and diagnose colorectal cancer from tissue scans as well or better than pathologists, according to a new study.

Researchers have developed an artificial material which can respond to its environment, independently make a decision, and perform an action not directed by a human being. For example, a drone making a delivery might evaluate its environment including wind direction, speed or wildlife, and automatically change course in order to complete the delivery safely. The material incorporates 3 main...

Heat from a comet exploding just above the ground fused the sandy soil into patches of glass stretching 75 kilometers, a new study found.

Malaria, a pathogen transmitted into blood by mosquitoes in tropical climates, is typically thought of as a blood and liver infection. However researchers have detected antibodies primarily made in response to infections in the mucous membranes -- in such areas as the lungs, intestines, or vagina -- in study participants with malaria.

Pinnipeds -- a group including seals, sea lions and walruses -- are relatively recently derived marine mammals that evolved from terrestrial carnivorans and reentered the marine environment. Their recent adaptations to an amphibious lifestyle make their evolutionary anatomy of particular interest.

Women exposed to smoke from landscape fires during pregnancy are more likely to give birth to babies with low or very low birth weights, according to new findings.

Being with friends and family may be a positive experience for some voles but it is merely tolerable to others, suggests a new study.

Scientists have discovered that a deadly parasite, known to cause ill health in pregnant women and immunocompromised patients, could potentially be used to treat various types of tumors.

Incorporating energy efficiency measures can reduce the amount of storage needed to power the nation's buildings entirely with renewable energy, according to a recent analysis.

The potential of DNA structural properties in single-molecule electronics has finally been harnessed by researchers in a single-molecule junction device that shows spontaneous self-restoring ability. Additionally, the device, based on a 'zipper' DNA configuration, shows unconventionally high electrical conductivity, opening doors to the development of novel nanoelectronic devices.

Scientists may have identified a method of safely mimicking the weight-loss benefits of a plant compound that -- despite its harmful side effects -- hold critical answers to developing therapies for obesity.

The number of wild bees has fallen dramatically since 1990. An expert urges researchers to assume their responsibility and help save the insects who hold the key to upholding human food production.

After an anterior cruciate ligament reconstruction surgery, it's common to experience quadriceps weakness, which was thought to be caused primarily by muscle atrophy, or shrinkage.

Earth's atmosphere has a unique ability to cleanse itself by way of invisible molecules in the air that act as minuscule cleanup crews. The most important molecule in that crew is the hydroxyl radical (OH), nicknamed the 'detergent of the atmosphere' because of its dominant role in removing pollutants. New research will aid in building more accurate computer models of OH. The study has important...

The haze that blurs a blue sky or a beautiful skyline is caused by particulate matter, often made from pollution, less than 2.5 microns wide. Despite their microscopic size, PM2.5 are responsible for more than 4 million premature deaths every year. A new study shows that the pollution caused by consumption in the world's biggest economies leads to half of those deaths.

Natural sounds, and bird song in particular, play a key role in building and maintaining our connection with nature - but a major new study reveals that the sounds of spring are changing, with dawn choruses across North America and Europe becoming quieter and less varied. An international team of researchers led by the University of East Anglia (UEA) developed a new technique, combining...

An antibody effective against COVID-19 and its variants could provide a template for universal coronavirus vaccination.

Precambrian cratons -- some of Earth's oldest rocks -- were uninhabitable for microbes for much of their existence, with the longest period of habitability not much beyond a billion years, and many only for the past 50 million to 300 million years, according to a paper correlating Earth's deep biosphere with geologic history.

The development of transport infrastructure is a central issue for states, which spend billions to connect cities. But what is their real effect on the municipalities concerned? Researchers have looked at the evolution of the income composition of the population of cities in Switzerland once they are connected to the motorway network. By analyzing data from 1950 to 2010, they found that this new...

Psychology researchers have developed and validated a new tool for assessing how accurate people are at recognizing emotion in elementary school-aged children. The technique will facilitate research on understanding emotions of children -- and highlights that adults are often wrong when assessing the emotions of children.

New research building on AI algorithms has enabled scientists to create more complete models of the protein structures in our bodies - paving the way for faster design of therapeutics and vaccines.

More than two thirds (65.5%) of students are experiencing poor sleep quality and this is linked to mental health problems, new research suggests.

Exposing male crickets to artificial light at night (ALAN) can impair their activity cycles. According to the researchers, nocturnal chirping is the male's way of calling females to come and mate with him, and its disruption can interfere with reproduction processes and even endanger the entire species.

A study of rheumatology patients and clinicians has found that while the majority found phone or video consultations more convenient than face-to-face consultations, they viewed so-called telemedicine as less diagnostically accurate than in-person consultations and as having the potential to increase health inequalities and barriers to accessing appropriate care.
