Wake Forest sophomore receives prestigious award to study dangerous bacteria.
The notion that trillions of bacteria are packed into the human body is enough to give anyone the heebie jeebies.
But not all bacteria are bad, said Hannah Martin, a rising sophomore. On the contrary, there are ... Read More
Nano-biotechnologists have reported the discovery of a new, third class of biomotor, unique in that it uses a "revolution without rotation" mechanism. These revolution biomotors are widespread among many bacteria and viruses.

The technique addresses the problem of hidden reservoirs of HIV in the body, and could herald a new way of battling the viral infection.
Once HIV invades the body, it doesn’t want to leave. Every strategy that scientists have developed or are developing so far to fight the virus – from powerf... Read More
Here’s what we know about white-band disease: It has already killed up to 95 percent of the Caribbean’s reef-building elkhorn and staghorn corals, and it’s caused by an infectious bacteria that seems to be transmitted through the water and by coral-eating snails.
Here’s what we don... Read More
Until this year, the world had recorded 1,640 deaths from Ebola since the virus was discovered in 1976.
Then Ebola appeared in West Africa.
So far this year, 887 people have died of Ebola in West Africa, the World Health Organization said Monday.
To put that into perspective, more than ... Read More
After recording TWiV 296 with Linfa Wang, we drove to a nearby golf course. There we watched a colony of grey-headed flying foxes awaken and fly into the night.
Bugs that can co-operate best with each other are most likely to be able to jump to new species, including humans, a new study shows.
Bacteria interact by releasing molecules to help them adapt to their environment – for example, when killing competing infections in their victim. They co-ord... Read More
A U.S. hospital caring for two Americans carrying the deadly Ebola virus has tapped biosafety experts to ensure doctors, nurses and other staff do everything needed to prevent the virus from escaping from an isolation ward in Atlanta.
The two patients, humanitarian aid workers who became infe... Read More
A probiotic that prevents obesity could be on the horizon.
Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
“Of course it’s hard to spec... Read More
A flu virus acts like a Trojan horse as it attacks and infects host cells. Scientists at Rice University and Baylor College of Medicine have acquired a clearer view of the well-hidden mechanism involved.
Their computer simulations may lead to new strategies to stop influenza, perhaps even a o... Read More
The body’s assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the p... Read More
One of the human body’s first responses to a viral infection is to make and release signaling proteins called interferons, which amplify the immune system response to viruses. Over time, many viruses have evolved to undermine interferon’s immune-boosting signal, and a new study describes a mecha... Read More
The joys of anaerobic digestion
One U.K. grocery store plans to power itself using biogas harvested from its own unsold, rotting produce. Yum.
A Sainsbury's store in Cannock in central England is getting access to anaerobic digesters. The store plans to use electricity solely from the dige... Read More
Rapid expansion of this species, which is more aggressive than the species that is now spreading chikungunya into the Caribbean, is worrying scientists.
In the past few months, passengers at North American airports have been warned that travel to the Caribbean might result in an unwanted souv... Read More
Bacteriophages are viruses that infect bacteria, and in the great war between humans and pathogenic bacteria they can act as allies for both sides. Phages that destroy their host bacteria can be used as antimicrobial therapy, complementing or replacing antibiotics. On the other hand as phages ar... Read More
On Friday afternoon, the federal Centers for Disease Control and Prevention posted a guide explaining how hospitals should manage Ebola patients. Hospital workers entering a patient's room should wear:
- Gown (fluid resistant or impermeable)
- Eye protection (goggles or face shield... Read More
A smoldering debate about whether or not researchers should ever deliberately create superflu strains and other risky germs in the interest of science has flared once again.
Proponents of the work say that in order to protect the public from the next naturally occurring pandemic, they have to... Read More
A new combination drug therapy cures chronic hepatitis C in most patients also infected with HIV—and without the side effects of current treatments.
The advance is important, researchers say, because about a third of HIV patients in the United States also have hepatitis C. There are an estima... Read More
Bacteria’s ability to destroy viruses has long puzzled scientists, but researchers at the Johns Hopkins Bloomberg School of Public Health say they now have a clear picture of the bacterial immune system and say its unique shape is likely why bacteria can so quickly recognize and destroy their as...

Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution.
