The ReCell kit, hardly bigger than a designer sunglasses case, houses a miniature lab for harvesting skin basal cells.
Traditionally, treatment for severe second-degree burns consists of adding insult to injury: cutting a swath of skin from another site on the same patient in order to graft it over the burn. The process works, but causes [...]

Hemigraphis alternata, or purple waffle plant, one of the highest ratedornamentals for removing indoor air pollutants.

Air quality in homes, offices, and other indoor spaces is becoming a major health concern, particularly in developed countries where people often spend more than 90% of their time indoors. Surprisingly, indoor air has been reported to be as much [...]

New research finds that a quick glance at someone’s facial structure may be enough for us to predict their tendency towards aggression.
Angry words and gestures are not the only way to get a sense of how temperamental a person is. According to new findings in Psychological Science, a quick glance at someone’s facial structure may [...]

Researchers have identified a cellular pathway that may explain the link between alcohol consumption and cancer.

Alcohol consumption has long been linked to cancer and its spread, but the underlying mechanism has never been clear. Now, researchers at Rush University Medical Center have identified a cellular pathway that may explain the link.

LSD and ecstacy shown to be more effective against anxiety
disorders than Prozac, Zoloft and other “legal” drugs
A growing number of people are taking LSD and other psychedelic drugs such as cannabis and ecstasy to help them cope with a variety of conditions including anorexia nervosa, cluster headaches and chronic anxiety attacks.
The emergence of a community that passes [...]

Brain signals can drive arm movement in a monkey with a paralyzed arm.
A monkey with a paralyzed arm can still grasp a ball, thanks to a novel system designed to translate brain signals into complex muscle movements in real time. The research, presented at the Society for Neuroscience conference in Chicago this week, could one [...]

In a small study of 54 young adults, UF researchers found eating more plant-based foods, which are rich in substances called phytochemicals, seems to prevent oxidative stress in the body, a process associated with obesity and the onset of disease
The cheeseburger and French fries might look tempting, but eating a serving of broccoli or leafy [...]

UCI scientist Sheryl Tsai and colleagues have discovered what triggers a cancer-causing toxin to form on nuts and grains, which could lead to methods of limiting its production
A toxin produced by mold on nuts and grains can cause liver cancer if consumed in large quantities. UC Irvine researchers for the first time have discovered what [...]

Tomato seeds exposed to carbon nanotubes (right) sprouted and grew faster than unexposed seeds (left).
With potential adverse health and environmental effects often in the news about nanotechnology, scientists in Arkansas are reporting that carbon nanotubes (CNTs) could have beneficial effects in agriculture. Their study, scheduled for the October issue of ACS Nano, found that tomato [...]

 
British doctors have moved a step closer to carrying out what they hope will be the world’s first successful human womb transplant, giving hope to thousands of women who are unable to have children for medical reasons.
 

Man juggling several small balls.
Learning to juggle leads to changes in the white matter of the brain, an Oxford University study has shown.

Muscle cells (shown here) are grown on a biological scaffold.
A novel implant seeded with muscle cells could better integrate prosthetic limbs with the body, allowing amputees greater control over robotic appendages. The construct, developed at the University of Michigan, consists of tiny cups, made from an electrically conductive polymer, that fit on nerve endings and [...]

This machine uses mass spectrometry to make molecular maps of tissue during surgery.
In the hope of helping oncologists remove every piece of tumor tissue during surgery, researchers are developing new imaging tools that work in real time in the operating room. European researchers have now demonstrated that a chemical analysis instrument called a mass spectrometer [...]

Tool transfer upon recipient’s request.
The evolution of altruism has long puzzled researchers and has mainly been explained previously from ultimate perspectives—”I will help you now because I expect there to be some long-term benefit to me”. However, a new study by researchers at the Primate Research Institute (PRI) and the Wildlife Research Center (WRC) of [...]

Adult female Bagheera kiplingi eats Beltian body harvested from ant-acacia.
There are approximately 40,000 species of spiders in the world, all of which have been thought to be strict predators that feed on insects or other animals. Now, scientists have found that a small Central American jumping spider has a uniquely different diet: the species Bagheera [...]

A new study finds high rates of childhood exposure to violence and abuse in United States.
A new study from the University of New Hampshire finds that U.S. children are routinely exposed to even more violence and abuse than has been previously recognized, with nearly half experiencing a physical assault in the study year.

Above: CCD image sensor. Below: Optical fibers.
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2009 with one half to Charles K. Kao, Standard Telecommunication Laboratories, Harlow, UK, and Chinese University of Hong Kong “for groundbreaking achievements concerning the transmission of light in fibers for optical communication”, and [...]

Mothers who smoke during pregnancy put their children at greater risk of developing psychotic symptoms in their teenage years.
Mothers who smoke during pregnancy put their children at greater risk of developing psychotic symptoms in their teenage years.

This SHOULD be a headline in major newspapers, but due to big money manipulations it has not been picked up. Many communities have enacted smoking bans in public places, some of which have been in effect for several years. How is that affecting our overall health? According to an analysis of studies, the bans are significantly [...]

Paralyzed rats walk
Scientists recently used treadmill exercise, drugs, and electrical stimulation to train paralyzed rats to walk once again, demonstrating a way to possibly treat spinal injuries in humans, which at present are basically untreatable.

Sometimes you have to think that maybe a pig is mans best friend
When a hobby-store owner in Cincinnati sliced off his fingertip in 2005 while showing a customer why the motor on his model plane was dangerous, he went to the emergency room without the missing tip. He couldn’t find it anywhere. The doctor bandaged [...]

scientists have developed a pair of glasses that receive visual data from a camera mounted on a them and send the images to a chip attatched on the side of the eyeball.

Inspired by the success of cochlear implants that can restore hearing to some deaf people, researchers at MIT are working on a retinal implant [...]

Of the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth … none other than our faithful robotic explorer, Cassini.
NASA scientists are marveling over the extent of ruffles and dust [...]

For the first time, an experimental vaccine has prevented infection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible.  The World Health Organization and the U.N. agency UNAIDS said the results “instilled new hope” in [...]
