Researchers are testing a new drug that can kill a wide range of superbugs -- including some bacteria now resistant to all common antibiotics.

A new technique for mapping the forces that clusters of cells exert on their surroundings could be useful for studying everything from tissue development to cancer metastasis.

K.L. always knew he might be completely blind before reaching adulthood. Even as a child he realized something was wrong with his eyes. Although he could see enough to navigate the world in daytime, as soon as the sun se...

Argon. It's all around us. It's in the air we breathe, incandescent lights we read by and plasma globes many of us played with as children.

New research shows that animals on a prebiotic diet sleep better and are buffered from the physiological impacts of stress. The undigestible dietary compounds, found in fibrous foods and some dairy products, serve as nou...

Through a technique known as DNA origami, scientists have created the fastest, most persistent DNA nano motor yet. New findings provide a blueprint for how to optimize the design of motors at the nanoscale -- hundreds of...

Researchers have developed a promising molecular tool that targets and inhibits one of cell immortality's underlying gears: the enzyme telomerase.

Scientists have just shown that a metabolic pathway plays a determining role in Alzheimer's disease's memory problems. This work also shows that supplying a specific amino acid as a nutritional supplement in a mouse mode...

Researchers found that post-stroke patients re-grow a healthy microbiota in their mouth and gut when they revert to normal food intake from tube feeding. These results emphasize the need to actively normalize feeding in ...

Twenty-two are dead, more are missing, and many more are injured after a supercell storm spawned a series of tornadoes early Tuesday morning, including one that struck downtown Nashville.

The incubation period for the novel coronavirus SARS-CoV-2 is between one and 14 days, but could be as long as 24 days.

Each breath begins with hundreds of individual neurons haphazardly firing at low levels, then quickly synchronizing. The synchronization prompts activity that signals diaphragm and chest muscles to contract, causing expa...

US manufacturing and technology group Honeywell said Tuesday it will bring to market "the world's most powerful quantum computer" aimed at tackling complex scientific and business challenges.

Visceral fat impairs memory via proinflammatory interleukin-1 beta mediated microglia activation in the hippocampus.

During a conflict between two groups, oxytocin levels increase, influencing the medial prefrontal cortex. This results in a greater feeling of empathy among the group and a desire to seek revenge on rivals. The findings ...

Men evaluated the scent of sexually aroused women as more attractive and expressed an increase in their sexual motivations. Findings suggest the chemical signal of scent alone can elicit a sexual response in men.

More data on mild and asymptomatic cases is desperately needed.

Consumed alone, artificial sweeteners do not appear to have a negative impact. However, when consumed with carbohydrates, insulin sensitivity changes and the brain has a decreased response to sweet tastes.

Imagine a wire with a thickness roughly one-hundred thousand times smaller than a human hair and only visible with the world's most powerful microscopes. They can come in many varieties, including semiconductors, insulat...

Scientists have been interested in superconductors--materials that transmit electricity without losing energy--for a long time because of their potential for advancing sustainable energy production. However, major advanc...

Scientists have made a breakthrough in the search for a new, sustainable permanent magnet.

After fourth-generation synchrotrons were invented (these are particle accelerators, which are, in fact, giant research facilities), there was an urgent need for a fundamentally new optics that could withstand high tempe...
