Why cutting down rainforests may be driving 28,000 heat deaths a year‎

Tropical forests are hot, steamy places. But when large numbers of trees are cut down, they get even hotter. Our recent research in Nature Climate Change shows that clearing large areas of the rainforest exposes hundreds of millions of people to higher temperatures, increasing heat stress (when the body's way of controlling temperature fails) and, in some cases, contributing to death.

Study points to opportunity for governments to work with public on use of AI‎

A major new study suggests people's direct experience with artificial intelligence has little impact on their views about its role in government decision-making—while factual information about the technology can significantly shift public opinion. Professor Yotam Margalit (King's College London) and Dr. Shir Raviv (Tel Aviv University) tracked the attitudes of more than 1,500 workers in a controlled experiment designed to mimic real-world interactions with AI systems. The work is published in the British Journal of Political Science.

The dual self-assembly network: A new chapter in 3D-printable hydrogels‎

In the world of advanced materials, the ultimate goal is to create a substance that possesses the adaptability of biological tissue: it must be strong enough to maintain its shape, yet fluid enough to be molded. The research team at National Taiwan University (NTU) has achieved this balance by developing a sophisticated CGB hydrogel system, with their findings recently published in the journal Carbohydrate Polymers.

Coral reef science must adapt for a chance to outpace climate change, say experts‎

Scientists call for a major acceleration in coral assisted evolution research to help reefs cope with rapidly warming oceans. The study, published today (30 March), was led by Dr. Adriana Humanes, Newcastle University and Dr. Juan Ortiz, Australian Institute of Marine Science (AIMS). It highlights fundamental changes needed to generate knowledge fast enough to make these methods effective. The international team of 28 experts identified promising discoveries that highlight the potential of assisted evolution to help mitigate the impact of climate change in reefs.

It takes a village: How cooperative breeding has shaped Lake Tanganyika fish‎

"It takes a village to raise a child" doesn't apply merely to humans. Many species of mammals, birds, fish, and various invertebrates have evolved complex social care systems known as cooperative breeding. In these animal societies, offspring receive attention not only from their parents but also from other group members called helpers.

The revolution in dinosaur science started 50 years ago—here's what we have learned‎

The study of dinosaurs has been through a revolution in recent decades. The story began half a century ago, when Robert McNeill Alexander, a professor of zoology at the University of Leeds, showed how the speed of an animal could be calculated from the spacing of its footprints and its body size.
