US may fund research to create mixed human-animal embryos
Research that mixes human cells into animal embryos could get US government funds for the first time under a new proposal that has stoked concerns about ethics and the limits of science. Some say the research has the potential to spark major medical breakthroughs in diseases like Alzheimer’s and Parkinson’s or conditions like infertility, and could help grow organs for human transplant, which are in short supply. Critics,...
Repeated experiences of racism most damaging to mental health
New research by University of Manchester academics has revealed for the first time how harmful repeated racial discrimination can be on mental and physical health. Several studies have already linked racial discrimination to poor mental and physical health but no study has ever studied the impact numerous attacks over time have on a person’s mental health. The study, published by Dr Laia Becares and colleagues in the American...
We’re Lucky Climate Change Didn’t Happen Sooner
There is some consolation in how the fossil fuel-induced climatic changes we increasingly experience through droughts and storm surges are playing out. It could have happened sooner, and therefore already have been much worse. Luckily, the natural atmosphere already contained carbon dioxide, enough that the human-induced changes were relatively small, for a long time. Had these concentrations been even slightly lower, the effects of...
North American Forests Unlikely To Save Us From Climate Change
Forests take up 25 – 30 percent of human-caused emissions of carbon dioxide — a strong greenhouse gas — and are therefore considered to play a crucial role in mitigating the speed and magnitude of climate change. However, a new study that combines future climate model projections, historic tree-ring records across the entire continent of North America, and how the growth rates of trees may respond to a higher concentration of carbon...
Organic Computers Are Coming
A team of the Lomonosov MSU researchers in collaboration with their German colleagues from the Institute of Polymer Research in Dresden (Leibniz Institute) managed to find a molecule that, to their opinion, could give the impetus to the development of organic electronics. The results of the work were published in Advanced Materials. Scientists from the Moscow State University together with colleagues from Germany have found that a...
