The regular use of Caesarean sections is having an impact on human evolution, say scientists.
Fossils of possibly the earliest backboned four-legged animals to walk have been found in Scotland.
The UK has bought the capsule which sent Tim Peake into space and returned him to Earth.
Although progress is being made, up to US $906bn of company turnover is still tied to global deforestation, an assessment suggests.
Robot aircraft are to be tested in UK airspace to help refine systems that control autonomous planes.
European research ministers meeting in Lucerne, Switzerland, emphatically reaffirm their commitment to putting a robot rover on Mars in 2021.
Flooding across parts of the UK last winter was the most extreme on record, experts say.
Analysis of black organic fragments found in the Sutton Hoo boat burial reveals they are bitumen from Syria.
The leaders of four major global cities say they will stop the use of all diesel powered cars and trucks by the middle of the next decade.
Proposals by the Trump administration to roll back US environmental regulations are likely to foment opposition, say analysts.

Little is rarer than an observable quantum spin liquid, but now, tests reveal that a synthetic crystal with ytterbium as its base may house one at near absolute zero. It joins an extremely short list of materials believed house myriads of particles joined together in an observable vast, shared entanglement, or "spooky action at a distance."
Current approaches to dealing with burnouts in doctors on an individual case-by-case basis is not effective and the issue should instead be tackled with organization-wide initiatives, according to researchers.
Repeated dieting may lead to weight gain because the brain interprets the diets as short famines and urges the person to store more fat for future shortages, new research suggests.
Extermination of dingoes and the consequent loss of small mammals – not just overgrazing by livestock – have led to a rapid spread of woody weed shrubs across semi-arid Australia, a new study shows.
Aging is a key risk factor for a variety of devastating, chronic diseases, yet the biological factors that influence when and how rapidly cells deteriorate over time remain largely unknown. Now, for the first time, a research team has linked the function of a core component of cells' machinery -- which cuts and rejoins RNA molecules in a process known as "RNA splicing" -- with longevity in the roundworm. The finding sheds light on the biological role of splicing in lifespan and suggests that manipulating specific splicing factors in humans might help promote healthy aging.

In a first-of-its-kind look at human kidney development, researchers at The Saban Research Institute of Children's Hospital Los Angeles have isolated human nephron progenitor (NP) cells. Their results, published online in the journal Stem Cell Translational Medicine, will help scientists understand how these progenitor cells become renal cells in the developing fetus, and possibly offer a future way to foster renal regeneration after chronic kidney failure or acute injury.

For the first time, researchers from the Wellcome Trust Sanger Institute and their collaborators have been able to identify in human cancers two characteristic patterns of DNA damage caused by ionising radiation. These fingerprint patterns may now enable doctors to identify which tumours have been caused by radiation, and investigate if they should be treated differently.

Scientists from the Senckenberg and the Giraffe Conservation Foundation have analysed the genetic relationships of all major populations of giraffe in the wild. The large study on the genetic makeup of giraffe, published today in Current Biology, shows that there are four distinct giraffe species. Until now, only one giraffe species had been recognized. The unexpected results are based on analyses using several nuclear marker genes of more than 100 animals. The new insights are set to improve protection efforts of these endangered animals in Africa.

In research published online today in Science, a team of scientists describe a new therapeutic strategy to target a hidden Achilles' heel shared by all known types of Ebola virus. Two antibodies developed with this strategy blocked the invasion of human cells by all five ebolaviruses, and one of them protected mice exposed to lethal doses of Ebola Zaire and Sudan, the two most dangerous. The team included scientists from Albert Einstein College of Medicine, U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), Integrated Biotherapeutics, Vanderbilt University Medical Center, and The Scripps Research Institute.

Stanford University School of Medicine scientists have identified a brain circuit that's indispensable to the sleep-wake cycle. This same circuit is also a key component of the reward system, an archipelago of interconnected brain clusters crucial to promoting behavior necessary for animals, including humans, to survive and reproduce.
