Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.
It’s hard to keep up. But new Omicron sub-variants are emerging that may lead to reinfections and another spike in cases.
Our best chance of limiting the emergence of new recombinant COVID variants is to limit the spread of infections, using public health measures to slow and suppress the virus.
How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
