Researchers have created a virus in the lab that infects cells and interacts with antibodies just like the COVID-19 virus, but lacks the ability to cause severe disease. This safer virus makes it possible for scientists who do not have access to high-level biosafety facilities to join the effort to find drugs or vaccines for COVID-19.

A new image from the VLA dramatically reveals the extended magnetic field of a spiral galaxy seen edge-on from Earth.

New research shows that spider monkeys use collective computation to figure out the best way to find food.

Twitter mentions show distinct community structure patterns resulting from communication preferences of individuals affected by physical distance between users and commonalities, such as shared language and history. While previous investigations have identified patterns using other data, such as mobile phone usage and Facebook friend connections, research now looks at the collective effect of...

Spiral galaxies such as our Milky Way can have sprawling magnetic fields. There are various theories about their formation, but so far the process is not well understood. An international research team has now analysed the magnetic field of the Milky Way-like galaxy NGC 4217 in detail on the basis of radio astronomical observations and has discovered as yet unknown magnetic field structures. The...

Researchers combined complementary imaging techniques to explore the atomic structure of human enamel, exposing tiny chemical flaws in the fundamental building blocks of our teeth. The findings could help scientists prevent or possibly reverse tooth decay.

This device offers a significantly faster and easier method for detecting ammonia levels in blood, which can reach dangerous levels in people with certain diseases and genetic conditions.

Fighting cancer often means employing a suite of techniques to target the tumor and prevent it from growing and spreading to other parts of the body. It's no small feat -- the American Cancer Society predicts roughly 1.8 million new cases of cancer in the country in 2020, underscoring the need to identify additional ways to outsmart the runaway cells.

Researchers have developed the first non-invasive way of measuring athletes' push start performance.

Saccharibacteria within a mammalian host are more diverse than ever anticipated, according to recent research. The researchers also discovered that certain members of the bacteria are found in the oral cavity of humans, the guts of other mammals, and in groundwater.

A team of scientists has found that a fasting-mimicking diet combined with hormone therapy has the potential to help treat breast cancer, according to newly published animal studies and small clinical trials in humans.

Although wound survivability has increased over the last 80 years, the U.S. military's medical corps suffered some periods of backsliding during conflicts, recent analysis shows.

Biomedical engineers have engineered a method for simultaneously detecting the presence of multiple specific microRNAs in RNA extracted from tissue samples without the need for labeling or target amplification. The technique could be used to identify early biomarkers of cancer and other diseases without the need for the elaborate, time-consuming, expensive processes and special laboratory...

Scientists studying brown-throated three-toed sloths, where predators are extinct and food is more accessible, have found that the animals adapt to have a primarily diurnal, or daytime, schedule.

Episodes of social unrest rippled throughout Chile in 2019. Researchers specializing in economics, mathematics and physics in Chile and the U.K. banded together to explore the surprising social dynamics people were experiencing. Social media is changing the rules of the game, and previously applied epidemic-like models, on their own, may no longer be enough to explain current rioting dynamics.

The rediscovery of a lost planet could pave the way for the detection of a world within the habitable 'Goldilocks zone' in a distant solar system.

Machine learning performed by neural networks is a popular approach to developing artificial intelligence, as researchers aim to replicate brain functionalities for a variety of applications. A paper proposes a new approach to perform computations required by a neural network, using light instead of electricity. In this approach, a photonic tensor core performs multiplications of matrices in...

High-quality lab procedures are even more crucial to identifying effective drugs than previously thought, new research has revealed.

Site-directed mutagenesis facilitates the experimental validation of gene function and can speed up plant breeding by producing new biodiversity or by reproducing previously known gene variants in other than their original genetic backgrounds. However, its application is challenging in wheat owing to high genomic redundancy and highly genotype-dependent DNA transfer methods.

A series of autopsies conducted by LSU Health New Orleans pathologists shows the damage to the hearts of COVID-19 patients is not the expected typical inflammation of the heart muscle associated with myocarditis, but rather a unique pattern of cell death in scattered individual heart muscle cells.

Lego could be used as a practical tool to train doctors in anaesthetic skills according to new research that has shown a simple task using the building bricks can help improve technical skills - a finding that could improve medical training and patient safety.

Researchers have developed an ultrasensitive biosensing method that could dramatically shorten the amount of time required to verify the presence of the COVID-19 virus in a sample.

Researchers have shown by in vitro experimentation that changes of glycans in mouse epidermal stem cells may serve as a biomarker of aging. Further, by overexpression of specific glycogenes in mouse keratinocytes, they replicated the glycome profile of aging cells as well as their decreased proliferation ability. These findings hold promise for stem cell research into skin disorders, specifically...

Tastier pork comes from pigs that eat the barley left over after making the Japanese liquor shochu. A team of professional brewers and academic farmers state that nutrients in the leftover fermented barley may reduce the animals' stress, resulting in better tasting sirloin and fillets. Feeding distillation leftovers to farm animals can improve the animals' quality of life, lower farmers' and...
