A Las Vegas doctor has been implanting stem cells harvested from placentas into patients with multiple sclerosis, muscular dystrophy and other diseases in violation of federal law, according to a warning letter released by health officials
It sounds almost too good to be true: a cheap and simple drug that kills almost all cancers by switching off their “immortality”. The drug, dichloroacetate, has already been used for years to treat rare metabolic disorders and so is known to be relat
Ecologists at the Zoological Society of London modeled the energy budgets of land-dwelling carnivores and arrived at a 1-ton limit as the maximum sustainable mass for these meat-eating mammals. After that, there is a huge pay-off for each kill mad
A strange ancient skull recently uncovered adds to mounting evidence that humans and Neanderthals interbred and suggests that humans evolved considerably after settling the European continent some 40,000 years ago.
Putting to rest a 200-year-old mystery, scientists say Napoleon Bonaparte died from an advanced case of gastric cancer and not arsenic poisoning as some had speculated.
First came kidney, liver and heart transplants. Then a few doctors started transplanting hands. French surgeons even did a face. Now, doctors are planning the first womb transplant in the United States.
Thai fisherman have stumbled upon a rare giant terrapin, a species that many thought was extinct in the waters around Thailand's coast, a conservation organisation said.
Long baffled by their origin, scientists now have evidence that these charcoal-colored diamonds formed in outer space. Analyzed the hydrogen in black diamond samples indicated that the mineral formed in a supernova explosion.
Stem cells nearly as powerful as embryonic stem cells can be found in the amniotic fluid that protects babies in the womb, U.S. researchers reported. They used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory an
Scientists have discovered a second species of bat with adhesive organs, or suckers, attached to its thumbs and hind feet, allowing the creatures to climb and cling upright to smooth tree leaves.
The new technology attaches nanoparticles to clothing fibers using microwaves. Then, chemicals that can repel water, oil and bacteria are directly bound to the nanoparticles. These two elements combine to create a protective coating on the fibers of
Alink between a gene and herpes simplex 1, or HSV. The form of the ApoE gene called ApoE-4 is the leading known risk factor for Alzheimer’s. And HSV is the form of herpes that causes cold sores around the mouth. More than 80 percent of Americans are
Scientists in Italy believe they have uncovered a murder — 400 years after it is thought to have taken place. Historians have long suspected that Francesco de' Medici, Grand Duke of Tuscany, and his second wife were poisoned — by Francesco's
U.S. and Japanese scientists reported they used genetic engineering to produce cattle that resist mad cow disease. They hope the cattle can provide dairy products, gelatin and other products free of the brain-destroying disease,
A brain hormone linked to the onset of puberty in teens also appears to turn down the Siberian hamster’s libido and reproduction during winter months, scientists report.
By probing the brain of Aplysia, researchers identified more than 100 genes similar to those associated with all major human neurological diseases and more than 600 genes controlling brain development.
Increasingly scientists are discovering unusual mechanisms by which fish make and hear secret whispers, grunts and thumps to attract mates and ward off the enemy.
A fossil of a leaf-imitating insect from 47 million years ago bears a striking resemblance to the mimickers of today. Leaf imitation is an ancient and successful evolutionary strategy that has been conserved over a relatively long period of time.
Researchers found a strong connection between obesity and the levels of certain types of bacteria in the gut. That could mean that someday there will be novel new ways of treating obesity that go beyond the standard advice of diet and exercise.
People with higher levels of vitamin D have a markedly reduced risk of developing multiple sclerosis (MS), according to a study published that may point to a promising way to protect against the disease.
The smallest form of life known to science just got smaller. Scientists found the microbes living in a remarkably inhospitable environment, drainage water as caustic as battery acid from a mine in Northern California. The microbes, members of an anci
A Japanese research team has succeeded in filming a giant squid live — possibly for the first time — and says the elusive creatures may be more plentiful than previously believed. Giant squid are the world's largest invertebrates. Because they li
A British mother could get into the record books after she gave birth to identicle twins and a single baby at the same time -- from two wombs -- in what is believed to be a world first.
The fossil bones of what may have been Europe's largest animal ever, a new type of dinosaur, have been discovered in Spain. Discovery of the sauropod, estimated to have weighed between 40 and 48 tons, is reported in Friday's issue of the jour
In an evolutionary twist, Flora the Komodo dragon has managed to become pregnant all on her own without any male help. She is carrying seven baby Komodo dragons.
Dozens of new species of animals and plants including a catfish with protruding teeth and a tree frog with striking bright green eyes have been found in the past year in the forests of Borneo.
By generating the proper brainwaves—picked up by a cap with electrodes that sense the signals and reflect a person's instructions—scientists can instruct a humanoid robot to move to specific locations and pick up certain objects.
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
By studying blindfolded college students who crawled through grass to sniff out a chocolate-scented trail, scientists say they've found evidence of a human smelling ability that experts thought was impossible. Information from each nostril to get
At the height of the flu pandemic in 1918, William H. Sardo Jr. remembers the pine caskets stacked in the living room of his family's house. Church services were banned. Ill in the morning, dead by night.
