Princeton University officials decided Monday to make available a meningitis vaccine that hasn't been approved in the U.S. to stop the spread of the sometimes deadly disease on campus.

Ten years after the SARS outbreak, scientists have uncovered genome sequences of a new virus closely related to the SARS coronavirus that erupted in Asia in 2002 to 2003, which caused a global pandemic crisis.
Veterinary researchers have helped identify the origin and possible evolution of an emerging swine virus with high mortality rates that has already spread to at least 17 states. They have traced the recent U.S. outbreaks to a strain from the Anhui province in China.
DNA analysis conducted by a British genetics professor suggests that he has solved the mystery of the Abominable Snowman— the elusive ape-like creature of the Himalayas. He thinks it's a bear.
Three U.S.-based scientists won this year's Nobel Prize in chemistry on Wednesday for developing powerful computer models that researchers use to understand complex chemical interactions and create new drugs.
A 30-year-old infertile woman gave birth after surgeons removed her ovaries and re-implanted tissue they treated in a lab, researchers report. The experimental technique was only tried in a small group of Japanese women with a specific kind of infertility problem, but scientists hope it can also help women who have trouble getting pregnant due to age.
Four people have been hospitalized and 160 quarantined after a 15-year-old boy who ate marmot meat died of the bubonic plague last week, the Kyrgyz Ministry of Health said today. The ministry in the Central Asian nation said the boy told medics he spent the previous week camping in the mountains where he had eaten barbecued marmot, a large ground squirrel that typically lives in mountainous areas.
All organs in our body rely on stem cells in order to maintain their function. The skin is our largest organ and forms a shield against the environment. New research results from BRIC, University of Copenhagen and Cambridge University, challenge current stem cell models and explains how the skin is maintained throughout life.
Studying the expression of genes that are dependent on vitamin D makes it possible to identify individuals who will benefit from vitamin D supplementation. Population-based studies have shown that vitamin D deficiency may increase the risk for chronic diseases and weaken the body's immune system.
A new strategy that cripples the ability of the dengue virus to escape the host immune system has been discovered by A*STAR’s Singapore Immunology Network (SIgN). This strategy could lead to the world’s first universal dengue vaccine candidate that can give full protection from all four serotypes of the virus.
Scientists have found an intriguing clue that suggests camels might somehow be involved in infecting people in the Middle East with the mysterious MERS virus. Since the virus was first identified last September, there have been 94 illnesses, including 46 deaths, from MERS, or Middle East espiratory syndrome, mostly in Saudi Arabia.
Chinese scientists have found the strongest evidence yet that a new bird flu strain is sometimes able to spread from person to person, but they are emphasizing that the virus still does not transmit easily. In a new study, Chinese researchers interviewed the family and close friends of a father and daughter both killed by H7N9 in eastern China to figure out how the virus might have spread between them.
A new study links heavy air pollution from coal burning to shorter lives in northern China. Researchers estimate that the half-billion people alive there in the 1990s will live an average of 5½ years less than their southern counterparts because they breathed dirtier air.
Johnson & Johnson is conducting a voluntary recall of millions of oral contraceptive packages in 43 countries outside the U.S., but says there's a "very low" risk that the flawed tablets could cause unplanned pregnancies. It's the latest in a series of about 40 product recalls announced by the U.S.-based company since 2009.
For decades, health officials have battled malaria with insecticides, bed nets and drugs. Now, scientists say there might be a potent new tool to fight the deadly mosquito-borne disease: The stench of human feet. In a laboratory study, researchers found that mosquitoes infected with the tropical disease were more attracted to human odors from a dirty sock than those that didn't carry malaria.
A simple vinegar test slashed cervical cancer death rates by one-third in a remarkable study of 150,000 women in the slums of India, where the disease is the top cancer killer of women. Doctors reported the results Sunday at a cancer conference in Chicago. Experts called the outcome "amazing" and said this quick, cheap test could save tens of thousands of lives each year in developing countries.
Three people were being treated Saturday for a new respiratory virus that is alarming global health officials, in the first cases in Italy, says the country's health ministry. A 45-year-old man who had recently returned from a 40-day visit to Jordan was hospitalized in Tuscany with a high fever, cough and respiratory problems, says the ministry.
A perfectly preserved woolly mammoth carcass with liquid blood has been found on a remote Arctic island, fueling hopes of cloning the Ice Age animal, Russian scientists say. The carcass was in such good shape because its lower part was stuck in pure ice, said Semyon Grigoryev, the head of the Mammoth Museum, who led the expedition into the Lyakhovsky Islands off the Siberian coast.
A raven-sized creature that lived about 150 million years ago is back on its perch, a new study says. Widely pegged as the earliest known bird, Archaeopteryx's status was called into question two years ago by Chinese scientists. They proposed yanking the prehistoric creature off the "bird" branch of the evolutionary family tree and moving it onto a closely related lineage of birdlike dinosaurs.
Three New York University researchers from China divulged results from a federally funded study to Chinese competitors in exchange for tuition, rent and other expenses, federal prosecutors say. Yudong Zhu, a U.S.-educated NYU professor, and Xing Yang, a lab engineer, were released on bail after appearing in federal court in Manhattan to face commercial bribery and other charges. They left court without speaking to reporters.
Two respiratory viruses in different parts of the world have captured the attention of global health officials — a novel coronavirus in the Middle East and a new bird flu spreading in China. Last week, the coronavirus related to SARS spread to France, where one patient who probably caught the the disease in Dubai infected his hospital roommate.
A 65-year-old Frenchman is hospitalized after contracting France's first case of a deadly new respiratory virus related to SARS, and French health authorities say they are trying to find anyone who might have been in contact with him to prevent it from spreading.
Scientists have discovered that immune cells in the brain can produce a substance that prevents bacterial growth: Namely, itaconic acid. Until now, biologists had assumed that only certain fungi produced itaconic acid. A team has now shown that even so-called microglial cells in mammals are also capable of producing this acid.
Even bacteria have a kind of “immune system” they use to defend themselves against unwanted intruders– in their case, viruses. Scientists are now able to show that this defense system is much more diverse than previously thought and that it comes in multiple versions.
A 2-year-old girl born without a windpipe now has a new one grown from her own stem cells, the youngest patient in the world to benefit from the experimental treatment. Hannah Warren has been unable to breathe, eat, drink or swallow on her own since she was born in South Korea in 2010.
Chinese scientists have for the first time found strong evidence of how humans became infected with a new strain of bird flu: from chickens at a live market. Chinese scientists compared swabs from birds at markets in eastern China to virus samples from four patients who caught the new H7N9 virus. The scientists found the virus from one patient was nearly identical to one found in a chicken.
