In many people with autism and other neurodevelopmental disorders, different parts of the brain don’t talk to each other very well. Scientists have now identified, for the first time, a way in which this decreased functional connectivity can come about.

A team of researchers from Canada has developed a class of compounds which may help eradicate a neglected tropical disease that is currently hard to kill in its chronic form. The research was published ahead of print in Antimicrobial Agents and Chemotherapy.
Chinese authorities said Wednesday that a 73-year-old Chinese woman died after being infected with a bird flu strain that had sickened a human for the first time, a development that the World Health Organization called "worrisome."
British Prime Minister David Cameron says he hopes to kick-start an international effort to find a cure or effective treatment for dementia by 2025.
Global efforts to curb malaria are stalling after a drop in funds to buy bed nets, according to the latest report Wednesday from the World Health Organization. In 2010, 145 million bed nets were distributed; that fell to 92 million in 2011 and 70 million last year.
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.
A strain of bird flu that scientists thought could not infect people has shown up in a Taiwanese woman, a nasty surprise that shows scientists must do more to spot worrisome flu strains before they ignite a global outbreak, doctors say.
U.S. experts are raising the alarm over the spread of drug-resistant malaria in several Southeast Asian countries, endangering major global gains in fighting the mosquito-borne disease that kills more than 600,000 people annually.
Oman says officials are widening health checks following the country's first death blamed on a SARS-like virus that has been centered in neighboring Saudi Arabia.
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.
