In several small villages in the northwest of Spain, no one knew what made the water in their fountains turn a blood-like red.

Lead exposure in early childhood are associated with increased risk for sleep problems and excessive daytime sleepiness in later childhood, new research shows. This is the first longitudinal, population-based study that ...

How does a protein called connexin put the clamps on cancer? Researchers have now reported an explanation. In the future, cancer therapies could potentially be based on connexin molecules, the study suggests.

Two thyroid cancer biomarkers go through a clumping cycle that may interfere with cancer detection tests. New research explores a driving force behind the problem: a protein with a sweet tooth.

A new analysis of HIV incidence in 36 sub-Saharan African countries finds that new HIV infections rise significantly in the five years before armed conflict breaks out. The new study tracked HIV incidence statistics in 3...

Physicists at the University of Southampton have extended the theory of resonance fluorescence, a classic phenomenon in quantum optics, to 2D nanostructures that have novel light emission properties.

CRISPR-Cas9 is a powerful tool to edit genomes, but off-target edits are a concern. Now studies detail three checks the Cas9 protein makes to ensure it binds the right DNA and that the sequence matches the RNA primer suf...

Cryptosporidium parvum is a gastrointestinal parasite that can cause moderate to severe diarrhea in children and adults, and deadly opportunistic infection in AIDS patients. Because C. parvum is resistant to chlorine dis...

The genetics of an Incan child who was sacrificed about 500 years ago reveals details of the Native American expansion into the Americas.

People who get enough sleep are more likely to hit other heart health targets, too.

Physicists from the universities of Groningen and Nijmegen (the Netherlands) and Hong Kong have discovered that transistors made of ultrathin layers molybdeendisulfide (MoS2) are not only superconducting at low temperatu...

Compared to other emergency responders, firefighters are more at risk for heart disease.

Physicists from the universities of Groningen and Nijmegen (the Netherlands) and Hong Kong have discovered that transistors made of ultrathin layers molybdeendisulfide (MoS2) are not only superconducting at low temperatu...

A new study delivers the first evidence that water in ancient dust grains collected at the heart of an infant Earth during its formative years.

Rather than arriving by meteorite, Earth's water seems to originate in the very dust that formed our planet - the same could be true of other worlds

Yet another of the immense glaciers in Greenland is retreating and crumbling faster as warmer waters undermine it

Small steps can equal big changes when it comes to diabetes. A doctor explains how to lower your risk for diabetes and pre-diabetes.

Anywhere you look in the modern world, you'll see humans translating science fiction into science fact. We make predictions about a far off future, and then our curiosity drives us...

For at least the past 50 years, about half of all Earth's carbon dioxide emissions - human and natural - have been absorbed by the land and oceans. Scientists are trying to understand how much more CO2 this global carbon...

Scientists are studying the heat trapping behavior of CO2 released by land-clearing and accidental forest fires vs. factories in large urban centers. The data producing this simulation were taken during a 5-day period in...

It's no secret that a high-fat, high-cholesterol "junk food" diet has been linked to major health problems, including high blood cholesterol and the buildup of plaques in the arteries, known as atherosclerosis. Now new r...

NASA Orbiting Carbon Observatory 2, launched in July 2014, measures global atmospheric carbon dioxide. Data from May to August 2015 were compiled to create this visualization.
