New research shows giant pandas have a stronger immune system than previously known, because the panda immune system develops different antigens depending on where it lives.
This genetic diversity is a natural defense against extinction, because it means a single pathogen cannot wipe out the ... Read More
How often do you clean your hands? A study at Rhode Island Hospital observed staff on 161,526 occasions to monitor how often they cleaned their hands (ie, hand hygiene) between July 2008 to December 2012 and found that hand hygiene compliance improved from 60 percent to 89 percent. The study is ... Read More
When cells grow and proliferate, they need to produce large amounts of protein. All this protein is made by ribosomes, therefore rapid growth requires many ribosomes. Because ribosomes are expensive machines for the cell, the cell needs to use them efficiently. In a new study, published in PNAS,... Read More
So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus can’t replicate efficiently in the nose. The new study, using weakened viruses in the lab, supports the conclusions of controversial research published in 2012 which demonstrated th... Read More
A compound found in soybeans can be used in new treatments to inhibit the deadly HIV infection, scientists claim. Read More
Researchers at Case Western Reserve University and Cleveland Clinic Lerner Research Institute have discovered recent genetic mutations in a parasite that causes over 100 million cases of malaria annually -- changes that may render tens of millions of Africans who had been considered resistant, s...

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
A method that promises to reduce by more than half the time it takes health officials to identify Salmonella strains has been developed by researchers in Penn State's College of Agricultural Sciences.
The finding is important because it promises to significantly speed up the response to many ... Read More
Italian officials should not go ahead with expensive clinical tests of an unproven stem-cell therapy that has no good scientific basis.
The Italian government is planning to oversee a clinical trial of a controversial stem-cell therapy. There are many reasons for the trial to be stopped — and... Read More
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
Biologists dissected tissue samples from an oarfish carcass found in California and discovered the creature was hosting quite a few parasites.
“Our findings say that these are actually majorly parasitized fish,” says Armand Kuris, professor of zoology at the University of California, Santa Ba... Read More

Want to ensure that miracle drugs can no longer perform miracles?
Then do what some physicians and industrial livestock farmers have done for years: Overprescribe antibiotics to people, and use them cavalierly in farm animals to promote growth or prevent infections before they even occur.

In a barn outside Manhattan, Kan., researchers from Kansas State University are trying to solve the riddle of bovine respiratory disease. They're sticking plastic rods down the noses of six-month old calves, collecting samples of bacteria.
"This bacteria, Mannheimia haemolytica, lives in most... Read More
Working with a synthetic gene circuit designed to coax bacteria to grow in a predictable ring pattern, Duke University scientists have revealed an underappreciated contributor to natural pattern formation: time.
In a series of experiments published Oct. 8, 2013, in the journal Molecular Syste... Read More
Scientists have a promising new approach to combating deadly human viruses thanks to an educated hunch by University of California, Riverside microbiology professor Shou-Wei Ding, and his 20 years of research on plants, fruit flies, nematodes and mice to show the truth in his theory.

If we could somehow rewind the history of life to the dawn of the animal kingdom, it would be unlikely that we humans would ever evolve, the evolutionary biologist Stephen Jay Gould argued. The history of life was shaped by too many flukes and contingencies to repeat its course.
Scientists ca... Read More
On 3 April 2013, the China Health and Family Planning Commission notified WHO of an additional four cases of human infection with influenza A(H7N9). The four patients are from Jiangsu province in eastern China. There is no link between the cases.
The patients include a 45-year-old woman with ... Read More
Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in t...
