A Sandia National Laboratories-led team has for the first time used optics rather than electronics to switch a nanometer-thick thin film device from completely dark to completely transparent, or light, at a speed of tril...

The price of silicon-based solar cells has been falling off a cliff for years now. In 1977, each watt of capacity for a silicon solar panel would cost you around $76. By 1987, that had dropped to $10. In 2017, according ...

A pioneering method has demonstrated its potential in a large study, showing that metabolic fingerprints from blood samples could render important new knowledge on the connection between food and health. The study finds ...

Blends of artificial sweeteners such as saccharin and cyclamate produce less of a bitter off-taste than each of the individual components, but the explanation for this puzzling phenomenon has been elusive ever since its ...

In mice, an infection-induced condition known as sepsis may increase the risk of life-threatening secondary infection by preventing recruitment of infection-fighting cells to the skin, according to new research.

Researchers have not only untangled an unusual wiring system that cancer cells use for carbohydrate metabolism, but also identified a natural compound that appears to selectively shut down this system in laboratory studi...

Scientists have programmed a 'robot' made of DNA to pick up and sort molecules into predetermined locations.

An investigational treatment that mimics a key clotting enzyme is effective, safe, and may one day eliminate the need for blood products for people with the rare, life-threatening blood disease hereditary thrombotic thro...

Investigators have uncovered a new genetic cause of mesothelioma: a genetic rearrangement in the ALK gene, observed in three patients with peritoneal mesothelioma. Unlike previously known causes, this new discovery point...

The first large-scale genetic study of people in Papua New Guinea has shown that different groups within the country are genetically highly different from each other. Scientists reveal that the people there have remained...

Thirty percent of type 2 diabetic patients don't begin insulin when it's initially recommended, with the average start time being two years later.

Medical researchers have demonstrated that the protein tyrosine phosphatase receptor type J (PTPRJ) inhibits leptin signaling and that induction of PTPRJ in the hypothalamus is a cause of leptin resistance.

A new mechanism has been discovered for storing information in synapses and a means of controlling the storage process. The breakthrough moves science closer to unveiling the mystery of the molecular mechanisms of memory...

Molecules brought to Earth in meteorite strikes could potentially be converted into the building blocks of DNA, researchers have shown.

A new study demonstrates the potential of wearable technology as a social-skills aid for children with autism spectrum disorder.

Researchers have created a chimera virus that allows the study of molecules to treat cancers caused by human herpes virus infection in mice models of disease.

Researchers have uncovered a new genetic cause for erythropoietic protoporphyria (EPP), a photosensitive blood disorder.

Whether a community is made up of people who spend their days entirely outside or those who rarely see sunshine, the amount of time residents spend outdoors can affect how Zika virus spreads throughout the population.

In an important step towards eradicating HIV-associated viral reservoirs, researchers have identified how the HIV virus hijacks the innate immune system to facilitate its replication and spread, thus gaining a foothold i...

Microscopic degradable polymer cubes stuffed with vaccines could spell the end of booster jabs, and lead to a single vaccine that protects against all diseases

Pulses of light that last billionths of a billionth of a second have helped unravel a mystery inside solid objects and could help us build better X-ray lasers

Giving antibiotics to people with cancer could improve treatment by stopping bacteria from degrading anticancer drugs
