The virus that has killed nearly 800 bottlenose dolphins off the East Coast has turned up in four whales that have washed ashore, a potentially troubling development if it is shown to be the cause of their deaths, a government marine expert said Thursday.
But it is too early to know whether c... Read More
You might not know it, but most of us are infected with the herpesvirus known as Epstein-Barr virus (EBV). For most of us, the virus will lead at worst to a case of infectious mononucleosis, but sometimes, and especially in some parts of the world, those viruses are found in association with can...

The virus causing Middle East respiratory syndrome emerged in 2012. It does not spread readily between people, but there are fears it could cause a pandemic if it ever starts. It has killed 76 of the 178 people known to have caught it so far, and there is no specific treatment. Shibo Jiang at Fu... Read More
New study shows healthy Red Sea corals carry bacterial communities within. Corals may let certain bacteria get under its skin, according to a new study by researchers at Woods Hole Oceanographic Institution (WHOI) and King Abdullah University of Science and Technology (KAUST) and soon to be publ...

A new study that analyzed about 80,000 gene sequences from flu viruses has revealed that birds may have had some help from horses in spreading the virus that eventually killed 50 million to 100 million people in the influenza pandemic in 1918. Two viral genes may have circulated for years before... Read More
The study confirms "the existence of an offensive biological warfare research programme in Nazi Germany." In January of 1942, Heinrich Himmler ordered the opening of an entomological laboratory in the Dachau concentration camp in southeastern Germany. But why? The stated purpose of the institut...

A potentially lethal fungal infection appears to gain virulence by being able to anticipate and disarm a hostile immune attack in the lungs, according to findings by researchers at Duke Medicine.
Defense mechanisms used by the fungus Cryptococcus neoformans enable it to lead to fatal meningit... Read More
Recently a number of children in California have developed a poliomyelitis-like paralysis. The cause of this paralysis is not yet known, and information about the outbreak is scarce. However, acute-flaccid paralysis is not uncommon (California would be expected to report about 75 cases a year, b... Read More
In contrast to air, the ocean represents a benign environment for most living organisms: With the exception of some harsh marine environments, the means of physicochemical properties are generally not far off the optimum of most species and their fluctuations are moderate, rarely exceeding biolo...

Insects are repelled by N,N-diethyl-m-toluamide, also known as DEET. But exactly which olfactory receptors insects use to sense DEET has eluded scientists for long.
Now researchers at the University of California, Riverside have identified these DEET-detecting olfactory receptors that cause ... Read More
While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More
Imagine swimming to the bottom of the sea, the water growing impossibly deep and dark the farther you travel. At these depths, beyond the reach of the sun, live strange new sources of light. Fish, jellyfish, and even bacteria light up these midnight waters.
According to new research in PLOS O... Read More
WEDNESDAY, Oct. 23 (HealthDay News) -- A 3-year-old Mississippi girl apparently cured of HIV infection by aggressive treatment right after her birth remains free of the virus, her doctors report. Early treatment with a combination of potent antiretroviral drugs appears to have kept the virus fro... Read More
The word 'unnatural' is often used to describe what's considered weird or unusual. But is anything weirder than nature?
Just look at 17-year cicadas, poised to flood the U.S. East Coast after having stayed underground since Bill Clinton was President. And cicadas are just the start: Biology a... Read More
Lyme disease is often evident by a rash on the skin, but infections do not always produce similar rashes. This can make it difficult to detect the disease early, when antibiotic treatment is most effective. Researchers describe a new mathematical model that captures the interactions between dise...

In the spring of 2013 a strain of influenza virus that had never infected humans before began to make people in China extremely ill. Although the virus, known as H7N9, had evolved among birds, it had mutated in a way that allowed it to spread to men, women and children. Within several months H7N... Read More
The gastropod mollusc Scaphander lignarius —a marine invertebrate found in North Atlantic and Mediterranean water— is the first organism, besides bacteria, in which the biosynthesis of lignarenones, organic molecules involved in organism’s chemical defence, has been identified. This is one of th... Read More
TPC Wire & Cable Corp. ( www.tpcwire.com) announces the launch of their first antimicrobial cable product called DEFENDER® for the industrial food and beverage market.

A small cicada-like insect called the Asian citrus psyllid (Diaphorina citri) threatens the world's citrus industries, transmitting an incurable and lethal citrus disease. This notorious pest harbors two bacterial species within cells specially prepared for the purpose of symbiosis. Whereas thes... Read More
