UT Southwestern Medical Center at Dallas researchers have discovered a tumor-suppressor gene that, in fruit flies, simultaneously restricts cell proliferation and promotes cell death, a process that may also play an important role in the genesis of cancer in humans.

Removal of the gene, hippo, resulted in tumor formation in every organ of the fruit fly. The findings, which are currently online, will appear in an upcoming issue of Cell.

“This is one of the few genes that has been d

From 16 to 31 July, 32 international student teams of researchers will gather in Bordeaux, France, to fly their experiments in zero-gravity on board a specially adapted Airbus A-300.

This year’s Student Parabolic Flight Campaign, organised by ESA’s Education Office, will see experiments performed in a variety scientific areas including physics, human biology, material science and robotics, some using objects as diverse as jelly and moths.

People are becoming more tolerant of the use of cannabis, but there are still clear limits to what is acceptable in the area of illegal drug-taking, according to new research funded by the ESRC.

Views about cannabis have shifted considerably over the past two decades, with 41 per cent of Britons now supporting its legalisation – up from just 12 per cent in 1983. However, very few (eight per cent) endorse the view that adults should be free to take any drugs they wish, says the report into

Almost half the chance of developing acid reflux, which doctors refer to as GORD, may be down to our genes, and not just what we eat and drink, a twin study in Gut suggests.

Acid reflux (gastro-oesophageal reflux disease) is one of the most common digestive disorders in the developed world. It is thought that up to one in five people suffers from the characteristic heart burn and/or acid regurgitation every week. Regular sufferers are at increased risk of cancer of the gullet (oesophagus), n

Using XMM-Newton, astronomers have obtained the world’s deepest ‘wide screen’ X-ray image of the cosmos to date. Their observations show newly discovered clusters of galaxies and provide insights into the structure of the distant Universe…

Unlike grains of sand on a beach, matter is not uniformly spread throughout the Universe. Instead, it is concentrated into galaxies like our own which themselves congregate into clusters. These clusters are ‘strung’ throughout the Universe in a web-like st

During summertime ozone near the Earth’s surface forms in most major U.S. cities when sunlight and heat mix with car exhaust and other pollution, causing health officials to issue “ozone alerts.” But in other parts of the world, such as the tropical Atlantic, this low level ozone appears to originate naturally in ways that have left scientists puzzled. Now, NASA-funded scientists using four satellites can tell where low level ozone pollution comes from and whether it was manmade or natural.
