A structural analysis of llama-derived nanobodies interacting with SARS-CoV-2 describes three mechanisms the microscopic molecules use to disarm the virus and its variants, pointing to new therapeutic possibilities -- including a universal coronavirus vaccine.

Recently, a pair of NASA studies identified the most likely locations to find pieces of the Moon's mantle on the surface, providing a map for future lunar sample return missions such as those under NASA's Artemis program. If collected and analyzed, these fragments from deep within the Moon can provide a better understanding of how the Moon, the Earth, and many other solar system worlds evolved.

A team of researchers has recently discovered that fear plays an important, unrecognized role in the underdevelopment, and increased vulnerability, of backyard songbirds.

A new study finds that work place interruptions are beneficial to a sense of belonging and can counterbalance negatives such as lost productivity.

The average American eats roughly 22 teaspoons of added sugar a day -- more than three times the recommended amount for women and more than double the recommended amount for men. Although this overconsumption is known to contribute to diabetes and other disorders, the exact ways in which eating too much sugar sets the stage for metabolic diseases on a cellular level has been less clear. Now, a...

Scientists studied microorganisms from an underwater mountain in the Atlantic Ocean, pioneering a method that could open new windows into our understanding of how life survives deep under the sea -- or in space.

Researchers report advances in inpatient rehabilitation for acute stroke. Their findings indicate early intervention using the robotic exoskeleton for high-dose gait training may improve function.

Identification of protein signatures of remodeled airways may help develop therapies to improve long-term outcomes, according to new research.

Researchers at University of Notre Dame are developing an artificial neural network to read complex ancient handwriting based on human perception to improve capabilities of deep learning transcription.

Seeing the urgent need for change, a team of scientists from leading research universities, conservation organizations and government laboratories across the West has produced a synthesis of the scientific literature that clearly lays out the established science and strength of evidence on climate change, wildfire and forest management for seasonally dry forests. The goal is to give land managers...

New research reveals constraints can lead to learning in AI systems.

A study in mice shows that an experimental small molecule helped restore the removal of damaged mitochondria from dopamine-producing brain cells.

Using the World Mortality Dataset, the largest existing collection of mortality data, researchers have tracked the impact of COVID-19 across more than 100 countries.

Physicists have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses a classical machine-learning algorithm that closely mimics the behavior of near-term quantum computers.

Researchers have determined the location of natural blood-pressure barometers inside our bodies that have eluded scientists for more than 60 years.

A new study provides valuable new data that highlights how species extinction risk is accelerating due to rapid climate change and an increase in extreme climate events, such as glacial calving and sea ice loss.

A new study details the structure of a critical enzyme present in SARS-CoV-2, the coronavirus that causes COVID-19. This enzyme removes nucleoside antiviral medications from the virus's RNA, rendering many treatments ineffective. Scientists could use data uncovered in the new study to find ways to inhibit the enzyme, possibly leading to more effective treatments.

Researchers report that infantile spasms, a rare but serious seizure disorder in babies, appear to be the result of a molecular pathway gone awry. In their study of a mouse model of the disorder, the researchers discovered that genetic mutations associated with the disease impair a pathway that is involved in building new synapses in the hippocampus, a brain region essential to learning and...

Ecologists observe the diversity of insects on the edge of apple orchards on Lake Constance.

Smartwatches are handy devices for people to keep track of the number of steps they take per day or to track their mile time during a run. But they are also opportunities for scientists to understand people's physiological processes while they are going about their everyday lives.

Bioengineers have developed a technology capable of revealing the protein-protein interactions (PPI) among thousands of proteins in a cell, in a single experiment. The tool, called PROPER-seq (protein-protein interaction sequencing), allows researchers to map the PPI network from their cells of interest within several weeks, without any specialized resources such as antibodies or pre-made gene...

A key element to slowing metastasis in ovarian cancer is understanding the mechanisms of how tumor cells invade tissues. Biophysics researchers explain how microscopic defects in how healthy cells line up can alter how easily ovarian cancer cells invade tissue. Using an experimental model, the group found that disruptions in the normal cellular layout, called topological defects, affect the rate...

When we speak, we use our auditory and somatosensory systems to monitor the results of the movements of our tongue or lips. Since we cannot typically see our own faces and tongues while we speak, however, the potential role of visual feedback has remained less clear. Researchers explore how readily speakers will integrate visual information about their tongue movements during a speech motor...

Scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how complex flow patterns and mechanical stresses in the stomach contribute to digestion. Researchers built a prototype of an artificial antrum to present a deeper understanding of how physical forces influence food digestion based on fluid dynamics....
