The “tripledemic” shines a spotlight on viral interference, in which one infection can block another.

Early reports that Omicron causes less-severe disease than Delta seem to be borne out, but it’s not yet clear to what extent that’s due to the variant itself versus the populations it’s infecting.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

As much as rainforests or deep-sea vents, the human gut holds rich stores of microbial chemicals that should be mined for their pharmacological potential.

George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.

Meet some of the people featured in the June 2019 issue of The Scientist.

Transposon mutagenesis give scientists a rare look at the most important interactions within microbial communities.

Molecules produced by resident bacteria and their hosts may signal immune cells to attack the body’s own tissues.

Ned Shaw US scientists have reason to feel both heady and scared. The federal government recently released unprecedented billions of dollars to fund bioterrorism research. Yet, the merits of this sudden shift in focus are being debated, and some worry that the money will be squandered or wasted. "I have been really very upset by the focus on bioterrorism," says Stanley Falkow, professor of microbiology and immunology and of medicine at Stanford University. "Everybody's talking about it, but th

The Scientist’s annual competition uncovered a bonanza of interesting technologies that made their way onto the market and into labs this year.
