French scientists have identified genetic mutations in a small number of children with autism which could provide insight into the biological basis of the disorder. They sequenced a gene called SHANK3 in more than 200 people with autism spectrum diso
Nerve cells in the pancreas may be a cause of type-1 diabetes in mice. Defective nerve endings may attract immune system proteins that mistakenly attack the pancreas, destroying its ability to make insulin.
A procedure that encourages an egg to begin embryo development without being fertilized could suggest a new way to produce stem cells, at least for certain patients.
Creatures thriving at the hot and cold extremes of the marine environment have amazed scientists who are celebrating the discovery of 500 previously unknown species in the oceans in the past year.
Discovered an extinct animal the size of a small squirrel that lived in China at least 125 million years ago and soared among the trees. Earliest known example of gliding flight by mammals, and shows that mammals experimented with aerial life about t
Scientists appear to have found a fingerprint of Alzheimer's disease lurking in patients' spinal fluid, a step toward a long-awaited test for the memory-robbing disease that today can be diagnosed definitively only at autopsy.
They laid down a layer of nurturing proteins as a base, and then used a robotic inkjet-style machine to squirt tiny quantities of various proteins down on top, in a specific pattern. The mouse cells began to grow into bone-type cells
The bones of a baby plesiosaur have been recovered from an Antarctic island. In life, 70 million years ago, the five-foot-long long-necked animal .... The new fossil skeleton is one of the most complete of its type ever found.
Peering deep into the sea, scientists are finding creatures more mysterious than many could have imagined. At one site, nearly 2 miles deep in the Atlantic, shrimp were living around a vent that was releasing water heated to 765 degrees Fahrenheit. W
Patients and blood donors could be at risk of contracting vCJD, the human form of mad cow disease. A study of transfusion patients given blood contaminated with the human form of mad cow disease still alive are at "substantial" risk.
The giant moray eel is normally a lone hunter in the dark. Now scientists find these eels may at times hunt in the daytime in the Red Sea, and surprisingly cooperate with another predatory fish, the grouper, which is also normally a solitary predator
One nectar bat can launch its tongue one and a half times its body length, longer than any other mammal and second only to chameleons among vertebrates. The tube-lipped nectar bat (Anoura fistulata) was discovered in the cloud forests of the Andes of
Antibodies currently used irreversibly break down at high temperatures, often limiting extended use in the field. Past studies revealed that the binding regions of antibodies from Llamas and those from camels and sharks are unusually small, just one-
The emergence of humans in the universe might not tell us anything concerning the fundamental constants of nature as scientists have speculated, new theoretical findings argue.
Emperor penguins dive below the Antarctic sea ice in search of food, they can descend 5 times as deep as a human and can swim on a single breath for up to 20 minutes. How they manage these incredible feats could potentially help improve surgical proc
Famed paleoanthropologist Richard Leakey is giving no quarter to powerful evangelical church leaders who are pressing Kenya's national museum to relegate to a back room its world-famous collection of hominid fossils showing the evolution of human
A recent study published by the National Academy of Sciences cast doubt on the reality of Gulf War Syndrome as a specific disease or syndrome. About 60,000 of the nearly 700,000 Gulf War veterans began reporting health problems in the months and year
Vietnamese scientists have successfully cloned small pigs and monkeys, the Vietnam Biotechnology Institute said according to state media reports.
An extremely rare and well-preserved dinosaur nest containing fossil eggs with the embryos exposed goes up for auction this weekend, but at least one scientist is demanding the artifact be returned to a museum.
(No idea on topic) Bees have been trained to sniff out explosives, according to scientists at a US weapons laboratory, in a project they say could have far-reaching applications in national security and the war in Iraq.
A young woman, confined to a wheelchair, is told to think about moving another wheelchair in front of her, first to the left and then forward. As if by magic, the wheelchair follows her mental commands. "She was controlling the chair with her im
It is something one half of the population has long suspected - and the other half always vocally denied. Women really do talk more than men. In fact, women talk almost three times as much as men, [no comment]
Analysis of ancient sediment taken from the bottom of the Atlantic Ocean support the view that the dinosaurs' extinction was caused by a single rogue meteor striking Earth, and not by multiple space rock impacts, a new study finds.
The strangely intricate wrinkles and grooves around the nostrils of many bats apparently could help them "see" in the dark by focusing their sonar, scientists in China have found. The discovery could help scientists improve sonar and rad
Scientists made their first discovery of a volcanic eruption in progress 1.5 miles below the surface of the Pacific Ocean. The event was predicted at a site where earthquake activity had increased. The eruption was confirmed when eight of 12 seismome
Some 2.4 billion years ago when the Milky Way started upping its star production, cosmic rays started pouring onto our planet, causing instability within the living. Populations of bacteria and algae repeatedly soared and crashed in the oceans.
Humpback whales have a type of brain cell seen only in humans, the great apes, and other cetaceans such as dolphins. Might mean such whales are more intelligent than they have been given credit for, and suggests complex brains evolved more than once
In a discovery that highlights the promise of stem cell research, researchers say a "master" embryonic cardiac stem cell is able to produce all three types of cardiac tissue.
Scientists say they've discovered how a gene mutation linked to an inherited form of Parkinson's disease damages the brain. The LRRK2 gene produces malfunctioning proteins that stunt the normal growth and branching of dopamine-producing neuro
A research team at the Salk Institute for Biological studies has been able to regenerate a wing in a chick embryo. This new study adds to the evidence that mammals can also regrow limbs, an ability once thought to be restricted to certain amphibians
