A study of genetic sequences sheds light on the settling of the North American Arctic, from ancient "Paleo-Eskimos" to the modern-day Inuit.
Scientists have tracked the spread of Ebola in West Africa, revealing genetic clues to the course of the outbreak.
Astronomers have shown that dead stars known as white dwarfs can re-ignite and explode as supernovas.
Scientists in Iceland say they are examining several depressions, termed 'cauldrons', near Bardarbunga volcano, which could be a sign of an eruption.
All but essential travel to Sierra Leone, Guinea and Liberia should be avoided, the Foreign and Commonwealth Office warns British nationals.
Scientists produce a simple mathematical model that explains how a single sheepdog can herd a large number of sheep.
The climate impacts of the world's fossil-fuelled power plants are being underestimated because of poor accounting, say researchers.
A target number of badgers to be killed in this year's pilot cull to tackle tuberculosis in cattle is announced.
The last remaining population of the world's rarest bird, the Madagascar pochard, needs a new wetland home if it is to thrive again, a study reveals.
Harvard researchers develop a system to orientate small objects in any direction using magnetic levitation.

Three papers reveal that around three-quarters of cancer patients who have major depression are not currently receiving treatment for depression, and that a new integrated treatment program is strikingly more effective at reducing depression and improving quality of life than current care.
It’s common knowledge that teenage boys seem predisposed to risky behaviors. Now, a series of new studies is shedding light on specific brain mechanisms that help to explain what might be going on inside juvenile male brains.
Only recently has it become possible to accurately 'see' the structure of a liquid. Using X-rays and a high-tech apparatus that holds liquids without a container, a physicist has compared the behavior of glass-forming liquids as they approach the glass transition. The results are the strongest demonstration yet that bulk properties like viscosity are linked to microscopic ones like structure.
Social class can account for differences in how parents coach their children to manage classroom challenges, a study shows. Such differences can affect a child's education by reproducing inequalities in the classroom. With the widening gaps in educational outcomes between social classes, the researcher suggested that this study could help schools become more aware of these differences and make moves to reduce the inequalities.
A comet collision with Earth caused abrupt environmental stress and degradation that contributed to the extinction of most large animal species then inhabiting the Americas, a group of scientists suggests. The catastrophic impact and the subsequent climate change also led to the disappearance of the prehistoric Clovis culture, and to human population decline. Now focus has turned to the character and distribution of nanodiamonds, one type of material produced during such an extraterrestrial collision. The researchers found an abundance of these tiny diamonds distributed over 50 million square kilometers across the Northern Hemisphere.

The soil bacteria Streptomyces form filamentous branches that extend into the air to create spiraling towers of spores.
Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines.

A candidate Ebola vaccine could be given to healthy volunteers in the UK, The Gambia and Mali as early as September, as part of an series of safety trials of potential vaccines aimed at preventing the disease that has killed more than 1,400 people in the current outbreak in West Africa.

In response to an ongoing, unprecedented outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard University, in collaboration with the Sierra Leone Ministry of Health and Sanitation and researchers across institutions and continents, has rapidly sequenced and analyzed more than 99 Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests. The team reports its results online in the journal Science.

A big step in understanding the mysteries of the human genome was unveiled today in the form of three analyses that provide the most detailed comparison yet of how the genomes of the fruit fly, roundworm, and human function.

About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.
