Subatomic particle seen changing to antiparticle and back for the first time
Physicists have proved that a subatomic particle can switch into its antiparticle alter-ego and back again, in a new discovery revealed today. An extraordinarily precise measurement made by Oxford researchers using the LHCb experiment at CERN has provided the first evidence that charm mesons can change into their…

Please commit more blatant academic fraud
This week, I was thrilled to read about the first well-documented case of explicit academic fraud in the artificial intelligence community. I hope that this is the beginning of a trend, and that other researchers will be inspired by their example and follow up by engaging in even more blatant...

A new replication crisis: Research that is less likely to be true is cited more
Papers in leading psychology, economic and science journals that fail to replicate and therefore are less likely to be true are often the most cited papers in academic research, according to a new study by the University of California San Diego’s Rady School of Management.

The Achilles Heel of the Coronavirus
SARS-CoV-2 is critically dependent on a special mechanism for the production of its proteins. A collaborative team led by a research group at ETH Zurich obtained molecular insights into this process and demonstrated that it can be inhibited by chemical compounds, thereby significantly reducing viral replication in…
