On average, there are about 480,000 patients in hospitals in the United States -- each generating about 135 clinical alarms per day. But studies show that more than 90 percent of these alarms result in no action, and ala...

A new tool predicts the risk of Zika virus importation and local transmission for 189 countries.

Creating transgenic mice, while critical to biomedical research, is laborious and expensive, despite improvements since the advent of CRISPR-Cas9 gene editing. Now, biologists have invented a technique that simplifies, i...

Calcium is a key signalling agent in the information networks of life. As calcium ions cannot cross cell membranes directly, the rise and fall of calcium levels within a cell are controlled through a set of proteins know...

Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment.

One of Zika's mysteries is how the virus passes from an infected mother, through the placenta, to a developing fetus. The route may not be direct either -- transmission via multiple cell types may be necessary. A new stu...

By increasing the level of a specific microRNA (miRNA) molecule, researchers have for the first time restored chemotherapy sensitivity in vitro to a line of human pancreatic cancer cells that had developed resistance to ...

Skin, eye and hair pigmentation requires a delicate balance of acidity within the cellular compartments where melanin is made -- that balance is partly regulated, scientists now know, by a protein called TPC2.

The HPV vaccine is to be offered to 40,000 men who have sex with men, but campaigners have repeated the call to offer the jab to all adolescent boys

From techno beats to classical melodies, from jazz swinging to pop and rock riffs - the ATLAS experiment can play them all thanks to Quantizer.

Garbage, nutrients and tiny animals are pushed around, suspended in the world's oceans by waves invisible to the naked eye according to a new 3-D model developed by mathematicians at the University of Waterloo.

The blow-up BEAM habitat had its first test run on the International Space Station on Thursday, but the constraints of being packed for the trip kept it from inflating sufficiently, NASA says

One of the most striking discoveries of quantum information theory is the existence of problems that can be solved in a more efficient way with quantum resources than with any known classical algorithm.

The Rosetta spacecraft has detected biological components glycine and phosphorus emerging from its comet - suggesting life on Earth could have arrived on a ball of ice

Having an 'alcohol identity' puts college students at greater risk of having drinking problems, say researchers, adding that posting about alcohol use on social media sites is actually a stronger predictor of alcohol pro...

An algorithm for building DNA nanoparticles automatically has now been developed by researchers, paving the way to many more applications for 'DNA origami.'

Finding new, more effective and personalized treatments for cancer is the challenge of many researchers. The challenge has been successfully met by a team that has just synthesized and developed new drugs for melanoma.

The crisis of lead-contaminated drinking water in Flint, Michigan continues to make headlines, but it's just the most prominent example of an 'ongoing and needless tragedy of childhood lead poisoning,' according to a not...

The "Internet of Things" could make cities "smarter" by connecting an extensive network of tiny communications devices to make life more efficient. But all these machines will require a lot of energy. Rather than adding ...

The heart rate may be an indicator of a person's life expectancy. A research team has to this end analyzed an effect which at first seems paradoxical: Minor irregularities in the heartbeat are indicative of a healthy bod...

Testing cancers for 'addiction' to a gene that boosts cell growth can pick out patients who may respond to a targeted drug under development, a major new study reports. By measuring the number of copies of just one gene ...

Researchers have designed a device that can morph into different shapes, depending on the desired function or even who is holding it.
