The saola, an antelope-like bovine, is one of the world's rarest and most endangered mammals. In fact, it hasn't been observed in over 10 years. Researchers have now mapped the saola's complete genome, and they have used that knowledge to estimate the chances of saving it -- if it still exists.

New research shows that elevation changes and earthquakes in Italy's Campi Flegrei volcanic area are caused by rising pressure in a geothermal reservoir -- not magma or its gases, as commonly thought. Channeling water runoff or lowering groundwater levels could reduce risks for surrounding communities.

Scientists inserted DNA-encoding methylmercury detoxification enzymes into the genome of an abundant human gut bacterium. The engineered bacterium detoxified methylmercury in the gut of mice and dramatically reduced the amount that reached other tissues, such as the brain and liver. Mice given an oral probiotic containing the engineered microbe and fed a diet high in bluefin tuna had much lower methylmercury levels than expected, suggesting that a probiotic might eventually make it safer for people to consume fish. Researchers performed the tests using pregnant mice and found lower levels of methylmercury in both maternal and fetal tissues, and lower signs of mercury toxicity in the fetal brain.

Tackling HIV continues to be a major public health challenge, mainly because the persistence of viral reservoirs means that people living with HIV need to take lifelong antiretroviral treatment. But some individuals, known as 'post-treatment controllers,' are able to maintain an undetectable viral load even after stopping treatment. Scientists have now identified specific immunogenetic characteristics in a group of these individuals. The research provides novel information about the immune mechanisms associated with HIV control in the absence of antiretroviral treatment and offers new prospects for the development of immunotherapies aimed at achieving remission or a cure for HIV infection.

Scientists have produced one of the most neutron-rich isotopes, hydrogen-6, in an electron scattering experiment. The experiment presents a new method for investigating light, neutron-rich nuclei and challenges our current understanding of multi-nucleon interactions.

By using antibodies from a human donor with a self-induced hyper-immunity to snake venom, scientists have developed the most broadly effective antivenom to date, which is protective against the likes of the black mamba, king cobra, and tiger snakes in mouse trials. The antivenom combines protective antibodies and a small molecule inhibitor and opens a path toward a universal antiserum.

Researchers have developed a revolutionary new way to find out the 'true age' of your heart using MRI. A new study shows how an MRI scan can reveal your heart's functional age -- and how unhealthy lifestyles can dramatically accelerate this figure. It is hoped that the findings could transform how heart disease is diagnosed -- offering a lifeline to millions by catching problems before they become deadly. The team say their cutting-edge technique is a 'game changer'.

Why do some ancient animals become fossils while others disappear without a trace? A new study reveals that part of the answer lies in the body itself. The research shows that an animal's size and chemical makeup can play an important role in determining whether it's preserved for millions of years -- or lost to time.

The Haenyeo, a group of all-female divers from the Korean island of Jeju, are renowned for their ability to dive in frigid waters without the aid of breathing equipment -- even while pregnant. A study shows that the divers' remarkable abilities are due to both training and genetic adaptation, including gene variants associated with cold tolerance and decreased blood pressure. The divers also showed pronounced bradycardia, or slowing of the heart rate, when they dived, but this trait is likely due to a lifetime of training, not genetics.

What is the secret to happiness? Does happiness come from within, or is it shaped by external influences such as our jobs, health, relationships and material circumstances? A new study shows that happiness can come from either within or from external influences, from both, or neither -- and which is true differs across people.
