Researchers unravel viruses' strategies to dodge immune systems Posted: 07 Nov 2016 08:29 AM PST As mammals evolve, so do mammalian viruses. In doing so, they develop creative and effective ways to counter and evade the antiviral responses of their mammal hosts' immune systems. Researching those mechanisms at the molecular level can reveal key insights into the principles of such strategies relevant to therapy development. An international team of scientists set out to do just that.

Most mammals have a greater life expectancy in zoos Posted: 07 Nov 2016 08:26 AM PST Life in the wild harbors the risk of predation, food shortages, harsh climates, and intense competition. Zoo animals, by contrast, are protected from these dangers. Researchers were part of an international team that studied over 50 mammalian species to determine whether the animals live longer in zoos than in the wild.

Sharks help prevent climate change Posted: 07 Nov 2016 08:26 AM PST Over fishing and shark finning may result on more greenhouse gasses and increased climate change, researchers suggest. Their new paper demonstrates the importance of protecting our oceans, and the importance of sharks in marine ecosystems.

Recovering critical, economically important metals from low-grade ores and waste Posted: 07 Nov 2016 08:26 AM PST The EU area is experiencing challenges in sourcing critical metals. Solutions to this are being sought by the a new project. Researchers are developing technologies for extracting valuable metals from metallurgical waste and low-grade ores, from which recovery is not yet economically viable. The research is serving European industry, which is dependent on the import of critical metals.

Proteins as an early warning system for type 1 diabetes? Posted: 07 Nov 2016 08:24 AM PST Certain proteins in the blood of children can predict incipient type 1 diabetes, even before the first symptoms appear, a team of scientists report.

New advance in RNA studies holds out hope for cancer drug development Posted: 07 Nov 2016 08:24 AM PST Scientists have designed a new method to find RNA structures linked to cancer. The formation of quadruplexes by RNA might allow new ways to control gene expression, they report.

Birth of massive stars is accompanied by strong luminosity bursts Posted: 07 Nov 2016 08:24 AM PST Astronomers are investigating the basic principles of the formation of stars. The birth of massive stars is still a mystery to us, because these stars are embedded in an extremely dense medium of gas and dust.
