There is not yet an ironclad scientific consensus on exactly how the coronavirus that causes COVID-19 is spreading, but experts are getting a pretty good sense of it. That understanding needs to be central to our strategy of combatting the virus with minimal collateral damage. This isn’t about over-reaction or under-reaction, but mis-reaction. For example,… Read More »

Scientists Discover a Key Metabolic Tuning Mechanism for Neurons

Neurons have a special mechanism that allows them to quickly boost energy production to support bursts of brain activity, according to a new study from scientists at Weill Cornell Medicine. The discovery, published Dec. 17 in Neuron, helps dispel the mystery of how neurons achieve the necessary metabolic flexibility to adjust rapidly to varying levels of signaling… Read More »

Scientists Were Hunting for the Next Ebola. Now the U.S. Has Cut Off Their Funding.

Their brains may not be bigger than normal, but monkeys created with human brain genes are exhibiting cognitive changes that suggest they might be smarter — and the experiments have ethicists shuddering. In the wake of the genetically modified human babies scandal, Chinese scientists are drawing fresh condemnation from philosophers and ethicists, this time over… Read More »
