Scientists have identified a gene that, in mice, is critical for these stem cells to divide correctly. Without it, they fail and die.

The silicon chip, which has supplied several decades' worth of remarkable increases in computing power and speed, looks unlikely to sustain this pace.

An increase in the CD163+/CD16+ monocyte subset could be a biomarker for the progression of HIV disease, according to researchers.

A new physics discovery explores why there is more matter than antimatter in the universe, turning to B-meson decay for answers.

Research show that graphene could be a leading candidate to replace silicon in applications ranging from high-speed computer chips to biochemical sensors.

New software is one of a new breed of computer programs able to accurately process the mountains of genome data flowing from the latest generation of gene decoding machines

An international team of researchers has successfully tested several Ebola vaccines in primates and are now looking to adapt them for human use, opening the door to a cure of a deadly disease.

An angioplasty balloon coated with a drug that reduces re-narrowing of the coronary arteries appears to be more effective than a drug-eluting stent.

A new medication that researchers had hoped would reduce the risk of arterial renarrowing after stenting has turned in a disappointing performance.

Researchers describe the development of gene probe eye drops that make it possible to monitor and detect tissue repair in the brain of living organisms using MRI.

Determining the structure of unknown natural compounds is a slow and expensive part of drug screening and development - but this may now change.

Many people are unaware of one of the greatest achievements of medical science - the eradication of smallpox from the world over 40 years ago.

Scientists have identified six new genes which play a role in the development of type 2 diabetes, and among the group is a prostate cancer gene.

Researchers have succeeded in a direct, three-dimensional visualisation of magnetic fields inside solid, non-transparent materials.

Marvell of Sunnyvale, California, has developed the first fully integrated, quad-port Gigabit Ethernet transceiver to support IEEE-defined 10/100/1000BASE-T copper and 1000BASE-SX/LX fibre-optic Gigabit Ethernet interfaces in a single device.
