Scientists vacuumed animal DNA out of thin air for the first time
The ability to sniff out animals’ airborne genetic material has been on researchers’ wish list for over a decade.

A genetic analysis hints at why COVID-19 can mess with smell
People with some genetic variants close to smell-related genes had an 11 percent higher risk of losing their sense of taste or smell.

Drug-resistant bacteria evolved on hedgehogs long before the use of antibiotics
A standoff between bacteria and antibiotic-producing fungi living on hedgehogs may have led to the rise of one type of MRSA some 200 years ago.

50 years ago, scientists were genetically modifying mosquitoes
In 1971, scientists turned to genetics to control disease-spreading mosquitoes without DDT. Today, there are a variety of pesticide-free methods.

A bacteria-virus arms race could lead to a new way to treat shigellosis
As bacteria that cause shigellosis evolve to escape a virus, the microbes may become less deadly, a hopeful sign for “phage therapy.”
