Nasa's New Horizons spacecraft has a new target to aim for following its historic flyby of Pluto.
A UK-built satellite delivered the first orbital picture to US disaster response coordinators following Hurricane Katrina. Ten years on, a British spacecraft has re-imaged the Mississippi Delta.
British neurologist and acclaimed author Oliver Sacks dies at the age of 82.
A French satellite system pictures a pile of rubble where the ancient Temple of Baalshamin at Palmyra in Syria used to stand.
A rocket mission to put a new spacecraft in orbit for London-based Inmarsat is declared a success.
A team of Nasa recruits begins a year-long isolation in a dome near a barren volcano in Hawaii, to simulate life on Mars.
The badger cull is to be extended into Dorset following pilots in Gloucestershire and Somerset, the government announces.
The government says it plans to significantly reduce subsidies paid to small scale green power installations.
Scientists say Knut, the famous polar bear that drowned at Berlin Zoo in 2011, had a type of autoimmune inflammation of the brain that is also recognised in humans.
An invasive caterpillar that feeds on hedges is starting to spread from its established base in London across the UK.

Researchers have found that molecular machines can be easily manipulated using very small mechanical energy, taking advantage of the property that they aggregate on the surface of water.
A group in Japan has developed tissue adhesive porous films that promote angiogenesis without using growth factors. This new technology may contribute to medical cost reduction making expensive growth factors-free.
Fatal bleeding is rare with extended dual antiplatelet therapy, according to a secondary analysis of the DAPT Study. Bleeding-related mortality accounted for a minority of deaths in patients treated with dual antiplatelet therapy beyond one year.
Prasugrel-based dual antiplatelet therapy is associated with increased major bleeding after stent implantation for high-risk patients with stable coronary artery disease, according to a secondary analysis of the BASKET-PROVE II trial. Major bleedings were more pronounced in elderly and low-weight patients and raise concerns about the safety of prescriptions in these patients.
Ticagrelor administered in the ambulance reduces ischaemic events 24 hours after primary percutaneous coronary intervention (PCI), according to new findings.

A study by the University of Liverpool has found that the genetic diversity of wild plant species could be altered rapidly by anthropogenic climate change.

Every organism--from a seedling to a president--must protect its DNA at all costs, but precisely how a cell distinguishes between damage to its own DNA and the foreign DNA of an invading virus has remained a mystery.

Researchers led by the UCLA Fielding School of Public Health examined HIV testing trends among adults ages 50 through 64 both before and after 2006, when the Centers for Disease Control and Prevention (CDC) recommended that most doctors automatically screen all patients for HIV regardless of whether they have symptoms.


Dr. Anita Göndör and her colleagues at Karolinska Institutet show that circadian genes 'take a nap' everyday at the periphery of the nucleus.
Mobility between different physical environments in the cell nucleus regulates the daily oscillations in the activity of genes that are controlled by the internal biological clock, according to a study that is published in the journal Molecular Cell. Eventually, these findings may lead to novel therapeutic strategies for the treatment of diseases linked with disrupted circadian rhythm.

Researchers from the Gladstone Institutes have revealed that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another.
