Scientists have discovered a novel genetic repair process that allows a hardy desert microbe to die and resurrect over and over again. Could lead to new forms of regenerative medicines and might bring dead cells in our own bodies back to life.
The 1918 Spanish Flu that killed up to 50 million people worldwide caused a severe immune response which may help to explain why it was so deadly. "What we think is happening is that the host's inflammatory response is being highly activated
The zebra tarantula produces silk secretions from tiny nozzle-like structures at the tips of its feet. The substance helps the spiders stick to vertical surfaces, ensuring a slip-free trek up a steep wall.
The parasitic dodder plant doesn't have a nose, but it knows how to sniff out its prey. The dodder attacks such plants as tomatoes, carrots, onions, citrus trees, cranberries, alfalfa and even flowers, and is a problem for farmers because chemica
Novartis Pharmaceuticals Corp., the U.S. unit of Swiss drugmaker Novartis AG said that at least three out of four patients given an experimental multiple sclerosis treatment were free of relapses for more than two years.
Too much testosterone can kill brain cells, researchers said in a finding that may help explain why steroid abuse can cause behavior changes like aggressiveness and suicidal tendencies.
Three new species of an ancient marine reptile, including a pregnant fossil, were recently discovered by University of Alberta paleontologists—under a pingpong table. The ichthyosaur fossils were unearthed from the Loon River Formation in Canada**
Microsoft Corp. co-founder Paul Allen decided to make a genetic atlas of the mouse brain. The atlas, begun in 2002 with $100 million from Allen's fortune, was declared finished on Tuesday, with fine-tuned information on 3,000 active genes -- a
Henrietta the chicken was living inconspicuously among 36,000 other birds at Brendle Farms for 18 months -- until a foreman noticed she had four legs. "It's as healthy as the rest," the farm's owner, Mark Brendle, told The Daily Ame
After a long day spent socializing or learning who to flirt with, fruit flies apparently need to sleep longer, shedding light on what sleep may actually do for humans, scientists now find.
Scientists say they have created a stem cell line from a human embryo that had stopped developing naturally, and so was considered dead. Using such embryos might ease ethical concerns about creating such cells, they suggested.
In just a few generations, the male crickets on Kauai underwent a drastic genetic change that rendered them incapable of belting out courtship songs. Typically, male field crickets sport curved wings, and by rubbing a sharp ridge of one wing with a r
The earliest known bird had flight feathers on its legs that allowed it to use its hindlimbs as an extra pair of wings. Supports the theory that early birds learned to glide and parachute from trees before achieving full-fledged flight.
[Uh Oh.] U.S. researchers said they had identified an "on-off" switch in the brain that controls the emotional response to fear, and said it might some day be manipulated to help patients with anxiety disorders.
Human embryonic stem cells can partly restore vision in blinded rats, and may offer a source of transplants for people with certain eye diseases, researchers at a U.S. company reported.
Scientists could generate a black hole as often as every second when the world's most powerful particle accelerator comes online in 2007. This potential "black hole factory" has raised fears that a stray black hole could devour our p
Deterioration of body and mind are the prices our bodies pay for protection against cancer as we grow older, new studies suggest. Scientists have discovered that a gene involved in tumor suppression also plays an important role in determining when
Scientists combing through undersea fauna off Indonesia's Papua province said they had discovered dozens of new species, including a shark that walks on its fins and a shrimp that looks like a praying mantis.
A farm in Wisconsin is quickly becoming hallowed ground for American Indians with the birth of its third white buffalo, an animal considered sacred by many tribes for its potential to bring good fortune and peace.
The freeze on air traffic after the September 11 attacks delayed the 2001-2002 flu season, and researchers were able to confirm what many had long suspected -- air travel could help spread a bird flu pandemic very efficiently.
Chicken feathers and rice straw could become commonplace in clothing in the future. Turned their eyes to the millions of tons of rice straw and chicken feathers available cheaply, abundantly and renewably worldwide as farming byproducts.
A woman in a vegetative state for five months appeared in brain scans to imagine playing tennis and to respond to commands, researchers reported. They said their study showed the woman was conscious despite her coma-like state,
A drug designed to treat premature ejaculation works well and is safe, researchers said. Dapoxetine, an antidepressant known as a selective serotonin reuptake inhibitor, is the first treatment specifically for premature ejaculation. P
The first genetic map of colon and breast cancer shows that nearly 200 mutated genes -- most of them previously unknown -- help tumors start, grow and spread, U.S. researchers reported.
Research suggests that healthy newborn infants do not have what doctors call "nasoaxillary reflex" -- a protective reflex that helps keep their nasal passages open. In adults lying on their side, the nasoaxillary reflex ensures that the
Scientists believe they may have finally identified the part of the brain that deals with the critical issue of matching words to everyday objects. Using brain scans of people suffering from Semantic Dementia they found the front end of the temporal
The artificial heart called AbioCor produced by Abiomed Inc, is made of titanium and plastic, is the size of a grapefruit and weighs two pounds.
The alignment of planets is purported to determine your love life in the daily horoscope. Now scientists say the formula that describes planetary attraction represents how insects spread disease. It's not the first time the cosmic math has bee
Many people have experienced the phenomenon of receiving a telephone call from someone shortly after thinking about them -- now a scientist says he has proof of what he calls telephone telepathy. [How many times didn't they call?]
The next several decades could prove a golden age for dinosaur hunters looking to discover new species of the ancient reptiles. A new statistical analysis predicts that more than 1,300 unique dinosaur genera await discovery by paleontologists.
