Researchers discover a new way to protect against high-dose radiation damage

Radiotherapy is one of the most effective ways to destroy cancer cells and shrink tumors. Around 50 percent of patients with tumors located in the gastrointestinal cavity (liver, pancreas, colon, prostate, etc) receive this type of treatment, which has increased cancer survival rates in recent decades. However, intensive radiation therapy not only damages tumor cells, but also healthy intestinal cells, leading to toxicity in 60 percent of treated patients. Whereas reversal of toxicity is observed after radiotherapy has concluded, 10 percent of treated patients develop gastrointestinal syndrome, a disease characterized by intestinal cell death, resulting in the destruction of the entire intestine and patient death.

More democracy: A second chance for climate politics

Hope was high when the Paris Climate Agreement was adopted 2015. Under the agreement, countries pledged to keep global warming well below two degrees Celsius. Five years later, the situation is sobering: Global emissions of carbon dioxide and other climate-relevant gases continue to rise. In an article in Science, Mark Lawrence and Stefan Schäfer of the Institute for Advanced Sustainability Studies (IASS) argue that the centralized approach to addressing global warming has failed and only greater democratic engagement can reanimate global climate politics.

Human contact plays big role in spread of some hospital infections, but not others

An observational study conducted in a French hospital showed that human contact was responsible for 90 percent of the spread of one species of antibiotic-resistant bacteria to new patients, but less than 60 percent of the spread of a different species. Audrey Duval of the Versailles Saint Quentin University and Institut Pasteur in Paris, France, and colleagues present these findings in PLOS Computational Biology.

Stanford Doggo: a highly agile quadruped robot

Researchers at Stanford University have recently created an open-source quadruped robot called Stanford Doggo. Their robot, presented in a paper pre-published on arXiv and set to be published by IEEE Explore, exceeds the performance of many state-of-the-art legged robots in vertical jumping agility.

A 'Noah's Ark' project for corals: Scientists race to save Florida Reef from killer disease

On a sunny afternoon in Dania Beach, a dozen scientists unloaded crates full of corals from a dive boat and onto a pickup truck. They gently removed each piece from large tanks on the deck and placed them inside smaller containers, which were slowly taken onshore.
