Watch as Bacteria Evolve Antibiotic Resistance in a Gigantic Petri Dish

By building a gigantic petri dish, researchers from Harvard Medical School and Technion-Israel Institute of Technology have produced a jaw-dropping visualization showing bacteria as it mutates to become resistant to drugs.

A NEW NATURAL ANTIBIOTIC HAS BEEN DISCOVERED IN THE HUMAN NOSE

The human nose is packed with bacteria. Some of its inhabitants can sicken us, but yet other nose-dwellers may hold the key to fighting them off. Today, scientists announced the discovery of a new antibiotic produced by bacteria in human noses. Called lugdunin, the compound can combat Methicillin-Resistant Staphylococcus aureus (MRSA). MRSA can cause a potentially life-threatening infection, and is resistant to some antibiotics.

Researchers want to block HIV with a ‘therapeutic’ virus

Despite the best efforts to date, a vaccine for HIV remains beyond our reach. It seems every time researchers get close, the virus mutates to stay a step ahead, creating a biological arms race. But a team of scientists at the University of Texas believe they may have found a way to hobble HIV and drastically reduce its virulence. They want to infect susceptible cells with a “good” virus first, one that will effectively immunize them against HIV.

MEET THE GERMS SHARING YOUR SEAT ON THE SUBWAY

The subway is crowded–and not just with people. Sharing your commute are trillions of invisible microbes. They’re on the seats, poles, ticket kiosks; pretty much on anything people hold, lean against, sneeze on, swipe, or bump into. “We’re constantly shedding bugs into our environment,” says Curtis Huttenhower, an associate professor at Harvard’s School of Public Health.
