The Epstein–Barr virus and its relatives in the herpesvirus family are known for their longevity. They persist in host tissues for years, causing diseases like mononucleosis, Kaposi's sarcoma and herpes, and are notoriously difficult to kill. University of California, Los Angeles, biophysicist Z... Read More
Most bacteria divide quite precisely and their daughter cells are often the same size. The reason for this accuracy is not really known, but it must be important because it is such a frequent phenomenon. This requires good measuring sticks, systems that calculate distance from the ends and restr... Read More
A study led by St. Jude Children’s Research Hospital scientists found the avian influenza A H3N8 virus that killed harbor seals along the New England coast can spread through respiratory droplets and poses a threat to humans. The research appears in the current issue of the scientific journal Na... Read More
A glass of orange juice in the morning is something many of us take for granted. But that might soon change thanks to a citrus disease affecting every major orange-growing region in the world.
The world's orange crop is being threatened by "citrus greening," a bacterial infection carried by a... Read More
Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.

A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago – nearly 60 million years before skeletal animals appeared during a huge growth spurt ...

(A) Bacillus subtilis, (B) Staphlococcus aureus and (C) Escherichia coli were grown on BHI media with varying concentrations of NaCl (0.85%, 5%, 7.5%, 10%, and 20%) at 37 degrees C for 24 hrs. Read More
The gut bacteria in horses are being researched at the University of Pennsylvania, in a series of projects that scientists hope will ultimately benefit animal and human health.
Researchers at the university’s School of Veterinary Medicine are leading five pilot projects as part of the wider i... Read More
New adhesives based on mussel proteins could be useful for naval or medical applications.
Shellfish such as mussels and barnacles secrete very sticky proteins that help them cling to rocks or ship hulls, even underwater. Inspired by these natural adhesives, a team of MIT engineers has designe... Read More
Wyoming’s resurgent uranium industry could get a further boost from University of Wyoming scientists, whose research on post-mining environmental restoration is yielding extremely promising results.
Research in UW laboratories has shown that stimulating growth of native bacteria could be a mo... Read More
A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.
That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.
Evolution is so important for biology, medicine and a genera... Read More
Antibiotic-resistant bacteria can share resources to cause chronic infections, Vanderbilt investigators have discovered. Like the individual members of a gang who might be relatively harmless alone, they turn deadly when they get together with their “friends.”
The findings, reported Oct. 8 in... Read More
Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.
When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More
Imagine you were forced to live in perpetually subzero temperatures, with no oxygen, no light, and way more salt than your system could handle. How would you manage? One way might be to get extremely small. At least, that seems to be what’s happening in a frozen Antarctic lake that’s cut off fro... Read More
Wolbachia are maternally transmitted endosymbionts that often alter their arthropod hosts’ biology to favor the success of infected females, and they may also serve as a speciation microbe driving reproductive isolation. Two of these host manipulations include killing males outrigh... Read More
A single dose of an investigational influenza drug was able to reduce the duration of fever and viral shedding, researchers said here.
In a combined analysis of two randomized placebo-controlled trials, the neuraminidase inhibitor peramivir (Rapivab), given by injection within 48 hours of sym... Read More
Natural selection favours those with a greater capacity to generate genetic variation.
Some gamblers succeed by spiriting cards up their sleeves, giving them a wider range of hands to play. So do some bacteria, whose great capacity for genetic variability helps them evolve and adapt to rapidl... Read More
