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.
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.
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.
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.
Using the CRISPR gene-editing tool, scientists from Harvard University have developed a technique that permanently records data into living cells. Incredibly, the information imprinted onto these microorganisms can be passed down to the next generation.
Ah, spring — time to get out of the house and be on the go. But when you’re out and really have to, you know, go, is that rest-stop bathroom the place to do it?
Cardiovascular disease can take many forms and numerous causes have been identified. Most of these have been associated with genetics and behavior. Yet there may be one other reason for heart troubles although it may seem highly unlikely.
