A powerful antibiotic that kills some of the most dangerous drug-resistant bacteria in the world has been discovered using artificial intelligence.#science #medicine #health
The drug works in a different way to existing antibacterials and is the first of its kind to be found by setting AI loose on vast digital libraries of pharmaceutical compounds.
Cancer doctors fear superbugs which can't be treated with antibiotics will soon remove chemotherapy as a treatment option for their patients, a survey has revealed. Cancer patients are more vulnerable to infections because the disease and its treatments can stop the immune system from working correctly.#science #medicine #health
Fossil-fuel production may be responsible for much more atmospheric methane than scientists previously thought, according to new research published today in the journal Nature. The results, if they hold, suggest that methane needs to be managed even more tightly than was accounted for in multilateral initiatives such as the 2015 Paris Agreement—not to mention many policies on the national and local level.#science #technology #environment
Tiny bubbles of ancient air trapped in ice cores from Greenland suggest we've been seriously overestimating the natural cycle of methane, while vastly undervaluing our own terrible impact.https://www.sciencealert.com/we-ve-vastly-miscalculated-how-much-methane-humans-are-spewing-into-the-atmosphere #climatechange #science
Methane is an 'invisible climate menace' - roughly 30 times more potent as a heat-trapper than carbon dioxide - and while some of this atmospheric gas is produced naturally, new research indicates humans are responsible for far more of it than we thought until now.
Before the industrial revolution, when humans began to extract and burn fossil fuels on the regular, natural methane emissions were an order of magnitude smaller than current estimates, the study suggests.
Today, this means our own methane emissions might be up to 40 percent higher than suspected.
A team of physicists at the University of Sussex has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation.#science #tech #imaging
Consuming a western diet for as little as one week can subtly impair brain function and encourage slim and otherwise healthy young people to overeat, scientists claim.#science #medicine #health
Researchers found that after seven days on a high fat, high added sugar diet, volunteers in their 20s scored worse on memory tests and found junk food more desirable immediately after they had finished a meal.
On Tuesday, the Japanese government announced it will begin clinical trials to test treatments for the deadly new coronavirus that’s engulfed China and spread to over two dozen countries. Rather than new drugs, they’ll be studying existing medications already used to treat HIV and other viral diseases. But why exactly are researchers hopeful that these drugs can be repurposed for the new coronavirus, and how likely are they to work?#science #medicine #health
