It's possible that people could spread Ebola many months after they have recovered from the deadly viral disease, a new study suggests.

These two closely related forces describe circular motion, but the meanings are often mixed up.

If sauropod dinosaurs cracked their tails like whips to deter competitors, here is how they might have worked

Young Latinos living in rural areas say they face discrimination when they obtain health care services -- a factor that could contribute to disparities in their rates for obtaining medical care and in their health outcom...

Searching for the precise, complexly folded three-dimensional structure of a protein can be like hacking through a jungle without a map: a long, intensive process with uncertain direction. Researchers developed a new app...

Low-income housing residents who live in 'green' buildings that are built with eco-friendly materials and energy-efficient features appear to have fewer 'sick building' symptoms than residents of traditionally constructe...

To help stop the spread of antibiotic resistance, scientists are urging hospitals around the country to stop buying meat from animals that were given antibiotics for growth promotion.

People who report being subjected to weight discrimination also have a greater risk of dying, say researchers, not because they may be overweight, but because of the apparent effects of the discrimination.

Women who visit mammography facilities with higher total interpretive volumes are more likely to benefit from screening, according to a new study. Research shows such facilities are significantly more likely to diagnose ...

Exotic particles such as dark matter could allow the formation of tunnels that cut through space-time. These so-called wormholes could be used to travel not only across the universe but also through time.

The telomerase enzyme is known to play a significant role in aging and most cancers. Scientists have discovered several major new insights about this enzyme and they are now able to see the complex enzyme's sub-units in ...

Stanford engineers have created a plastic "skin" that can detect how hard it is being pressed and generate an electric signal to deliver this sensory input directly to a living brain cell.

Adenosine triphosphate, or ATP for short, is the universal currency of energy among living things. It's the gasoline that drives our cellular motors, the necessary intermediate step between chemical and kinetic energy. B...

Findings of a new study reveal a key role of the BET protein family in the regulation of selected genes that control normal development and function of nerve cells.

A synthetic process will allow researchers to study a key molecule involved in diabetes, inflammation, and human aging.

The parasitic disease schistosomiasis is caused by a trematode flatworm, different species of which can affect either the intestine or the urinary tract. Mixed species (co-) infections are common, and research is needed ...

Using two complementary analytical approaches, scientists have, for the first time, identified the universe of genes in the human genome essential for the survival and proliferation of human cell lines or cultured human ...

To protect future generations against genomic havoc, defects in innate defense systems usually result in sterility. In animals, the main defense against troublemaking transposons is the Piwi-interacting RNA pathway. A te...

Engineers have created a plastic skin-like material that can detect pressure and deliver a Morse code-like signal directly to a living brain cell. The work takes a big step toward adding a sense of touch to prosthetic li...

Following the introduction of Cancer Care Ontario's 2012 cervical cancer screening guidelines, female patients were 50 per cent less likely to undergo screening for sexually transmitted infections, a new study has found.

Researchers studying areas of eastern Antarctica where snow is often stripped off the surface by wind, recently found that powerful gusts are actually vaporizing massive amounts of snow, rather than blowing and redistrib...

People who live hunter-gatherer societies in rural Africa and South America actually get less sleep than people who live in modernized, industrial societies, a new study finds.
