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.
Neurodegenerative diseases like Parkinson’s disease involve the death of thousands of neurons in...
Researchers from the Boston area, Mexico and Norway have completed a comprehensive genomic...
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.
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.
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.
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.
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 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.
Ancient DNA recovered from a series of skeletons in central Germany up to 7,500 years old has been used to reconstruct the first detailed genetic history of modern Europe. The study reveals a dramatic series of events including major migrations from both Western Europe and Eurasia, and signs of an unexplained genetic turnover about 4000-5000 years ago.
Scientists have identified 14 new genes which could have important consequences for future treatments of childhood arthritis. Researchers looked at DNA extracted from blood and saliva samples of 2,000 children with childhood arthritis and compared these to healthy people.
U.K. authorities say a 25-year-old man is suspected to have died from measles as an epidemic continues to sweep across south Wales. The outbreak has led to more than 800 infections and renewed discussions over the failure of some parents to vaccinate their children against the potentially fatal virus.
Researchers in Germany said Tuesday they have completed the first high-quality sequencing of a Neanderthal genome and are making it freely available online for other scientists to study. The genome produced from remains of a toe bone found in a Siberian cave is far more detailed than a previous Neanderthal genome sequenced three years ago by the same team.
Scientists have solved a problem that has frustrated biologists for years: Why different parts of proteins are made at different rates.
A usual reason for the need to change a prosthesis is its becoming detached from bone. A recent doctoral dissertation has come across several methods with which the adhesion of implants to bone can be improved.
Immune system B cells play a crucial role in the defence of pathogens: When they detect such an intruder, they produce antibodies that help to combat the enemy. They concurrently and continuously improve these molecules to more precisely recognize the pathogens.
GE Healthcare Life Sciences announced Jane Stout, from the United States, Anushree Balachandran, from Australia and Markus Posch, from the UK, as the winners of the GE Healthcare 2012 Cell Imaging Competition.
There’s reassuring news for pregnant women miserable with morning sickness: A very large study in Denmark finds no evidence that using a popular anti-nausea drug will harm their babies.
Researchers developing innovative biological and chemical techniques to image and diagnose cancer, have recently been investigating the use of magnetic beads in cancer diagnosis.
The origin of an innate ability the brain has to protect itself from damage that occurs in stroke has been explained for the first time.
Pour on the olive oil, preferably over fish and vegetables: One of the longest and most scientific tests of a Mediterranean diet suggests this style of eating can cut the chance of suffering heart-related problems, especially strokes, in older people at high risk of them.
A panel of advisers to the European Union's health agency has again rejected Vivus Inc.'s weight-loss drug for sale in Europe. Vivus, based in Mountain View, Calif., said that the Committee for Medicinal Products for Human Use confirmed its October decision to decline an application to sell the drug under the name Qsiva.
Reports that milk in the Balkans has been contaminated by a cancer-causing toxin have triggered a major health scare throughout the region, with authorities appealing for calm before official tests are conclusive. Senior agriculture official Goran Jesic claims on his website that out of 35 tested...
