Whirling electron vortices could help materials scientists to map the properties of nanomaterials in new detail. A technique, detailed in the September 16 issue of Nature, could be used in electron microscopes as part of the continuing quest to scale down the size of electronic chips.

In a discovery that sheds new light on the history of AIDS, scientists have found evidence that the ancestor to the virus that causes the disease has been in monkeys and apes for at least 32,000 years — not just a few hundred years, as had been previously thought.
That means humans have pres... Read More
Bacteria that are able to survive every modern antibiotic are cropping up in many U.S. hospitals and are spreading outside the USA, public health officials say.
The bugs, reported by hospitals in more than 20 states, typically strike the critically ill and are fatal in 30% to 60% of cases. Is... Read More
Menachem Shoham, PhD, associate professor and researcher in the department of biochemistry at the Case Western Reserve University School of Medicine, has identified new anti-pathogenic drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) harmless by...

We now know MicroRNAs (miRNAs) have big positive and negative impact on replication in DNA viruses, but what about RNA viruses like influenza? The authors of a new study just released by mBio went looking for miRNAs made by the flu virus, but they made an unexpected discovery that may provide i... Read More
However, I do believe their incredible numerical advantage grants them something - a certain Soviet despot supposedly said "Quantity has a quality all it's own" - that demands we stay on good terms w/ them. Read More
Bacteria dining on the oily feast in the Gulf of Mexico enjoyed a first course made mainly of gases in the months after the Deepwater Horizon oil spill, according to a study published in Science1 today. This may have primed the microorganisms to digest some of the more complex hydrocarbons in o... Read More
An extended-release formulation of nevirapine (Viramune) -- intended for once-daily dosing -- had similar efficacy in treatment-naïve HIV patients to the twice-a-day version commonly used, a researcher said here.
At the end of 48 weeks of therapy, 81% of patients treated with the extended-rel... Read More
The expansion of bacterial colonies is one of the classic research areas in biology. In a recent study, Ignasi Pagonabarraga, from the UB Department of Fundamental Physics, and researchers from the University of Edinburgh consider a new model that uses two parameters to reproduce the growth patt...

If there's life on Mars, we might smell it before we see it. A chemical involved in bad breath and flatulence in humans could lead us to alien microbes on the Red Planet.
The sulphur-containing molecule methyl mercaptan is naturally produced in significant quantities on Earth only by microbes... Read More
Farming practices have a significant impact on the diversity of beneficial microbial fungi known to play important roles in crop productivity, soil recovery and maintenance of healthy ecosystems, according to new research published in the journal Environmental Microbiology. The conclusions could... Read More
A biotech company plans to announce Tuesday that it has won a patent on a genetically altered bacterium that converts sunlight and carbon dioxide into ingredients of diesel fuel, a step that could provide a new pathway for making ethanol or a diesel replacement that skips several cumbersome and ...

Marie Pizzorno, an associate professor of biology and a molecular virologist, explains the differences between viruses and bacteria, how some bacteria are "good," and why it's difficult to predict the next epidemic.
Q: What is virology and what is the difference between viruses and bacteria?

Piglets hop, scurry and squeal their way to the far corner of the pen, eyeing an approaching human. “It shows that they’re healthy animals,” Craig Rowles, the owner of a large pork farm here, said with pride.
Mr. Rowles says he keeps his pigs fit by feeding them antibiotics for weeks after w... Read More
Friendly bacteria might not be an easy notion to wrap your brain around in the context of food these days.
Monica Corrado says bring 'em on. And she's not the only one.
Pack raw food into a jar, then seal it to keep out air, says the Takoma Park teacher of lactofermentation. Leave at roo... Read More
An Australian hospital that instituted aggressive infection control measures including daily facility-wide washdowns with high-strength bleach completely eliminated bloodstream infections with vancomycin-resistant enterococci (VRE) in high-risk wards, researchers reported here.

Sometimes the simplest solutions are best -- high school wrestlers may be able to reduce skin infections picked up during matches by cleaning exposed skin with a soap and water wipe after matches, a researcher said here.
A study of 151 high school wrestlers in Minneapolis-St. Paul, Minn., fou... Read More
As technology continues to move forward, fast DNA-based tests can offer diagnosis in hours compared to the days it can take for a bacterial culture to grow, often with the same level of certainty. Still, cultures remain the definitive gold-standard for confirming diagnosis. Have we finally rea... Read More
