For a period of 38 months after the stem cell transplant the patient continued to receive immunosuppressive treatment to prevent rejection of the stem cells. During this time the donor CD4 cells repopulated the mucosal immune system of the patient’s
Dwyer's team has created a customized camera that has 30 detectors made from a combination of sodium iodide and photomultiplier tubes, each measuring 3 × 3 inch. The device, which is approximately the size of a standard refrigerator, is also equippe
e bulb gives off 850 lumens, or around the same amount of light as a 60 watt incandescent bulb. The bulb, however, will only cost around $30 when it hits shelves soon. Two years ago, 60-watt equivalents sold for $100. A single LED bulb can save aroun
Modern analytical techniques can measure the atomic weight of many elements precisely, and these small variations in an element's atomic weight are important in research and industry. For example, precise measurements of the abundances of isotopes o
The new approach turns the conventional model on its head. Planet formation begins at distances in excess of 50 AU from the mother star, when random variations in the density of the protoplanetary gas cloud begin to attract more gas and so grow under
The eclipse begins on Tuesday morning, Dec. 21st, at 1:33 am EST (Monday, Dec. 20th, at 10:33 pm PST). At that time, Earth's shadow will appear as a dark-red bite at the edge of the lunar disk. It takes about an hour for the "bite" to expand and s
A Scottish medical research team has announced the discovery of an array of proteins associated with more than 130 brain diseases. For years neurological researchers have postulated that a gene might exists that could be linked to an array of brain d
“The ever-expanding list of state-sanctioned medical cannabis providers and ancillary businesses have easily become a multi-billion dollar industry in the United States, generating thousands of good jobs and paying tens – if not hundreds – of million
Honeybees are frequently used as a neurobiological model for learning—they can be trained, using positive or negative reinforcement, to retain information. In Amdam’s experiment, individual bees were strapped into a straw, where they learned to assoc
Nanorobots, incredibly small machines the size of molecules, operating at the current limits of human technology, will be able to clean arteries, destroy tumors, unblock clogged blood vessels in the brain, kill cancer cells and even find time to buil
Google has just unveiled Body Browser, a detailed 3D model of the human body. Running only in browsers that support the new WebGL graphics standard (currently just Google Chrome or the latest Firefox beta), Body Browser lets you peel back the body's
troke to different doses of aspirin for 12 weeks. All doses produced highly significant beneficial effects on two important and well documented markers of nitric oxide formation.
Did NASA blow it? NASA rushed to tell the world about a new lifeform discovered right here on Earth. The strange new life, found in the Mono Lake region of California, seemed to be a unique arsenic-based carbon life instead of the phosphorous based c
A recently published paper in Public Economics documents a dramatic “Lazarus effect” in AIDS-affected households in rural Kenya when infirmed members received anti-retroviral therapy (ART). The study found that not only did the health of those treate
he study by scientists at the universities of Cambridge and Edinburgh has raised hopes of a new treatment within 15 years for the disabling neurological condition, which affects millions of people worldwide.
An artificial bone-like material could speed up recovery from injury.
onventional gearboxes have always had some serious problems associated with needing to interrupt engine torque in order to change gear. Apart from increasing fuel usage, hydrocarbon and CO2 emissions, momentarily cutting power delivery to the rear wh
half-truths, faulty conclusions drawn from poorly conducted studies or created when a study gets cited out of context. Sometimes, what's claimed is even in exact opposition to what really occurs at a physiological level. Many people believe that

Stem cells can be transformed into the pancreatic cells needed to treat diabetes and into complex layers of intestinal tissue, scientists demonstrated in two experiments reported on Sunday.

hey showed how these scaffold proteins were successful in providing a stable surface outside the cell for chemical activity, e.g. the transformation of plant material into biofuels.
Professor Quentin Pankhurst, director of research at the Royal Institution have created a new method of targeting cancer cells and bombarding them with high-energy magnetic waves. The technology can project a high frequency pulse that's narrowly foc
Autism disorders affect one in 110 children in the U.S.--or perhaps more--but the method of diagnosing the condition, which is characterized by difficulties socializing and communicating, among other behavioral and emotional problems.
Increasing web connectivity in the developing world has been a focus of philanthropists, international bodies like the U.N., and individual states alike. But, like most grand visions, wiring entire countries for the Web is expensive.
Adding a face shield to the standard-issue helmet worn by U.S. troops could help protect soldiers from traumatic brain injury, the signature wound of the recent wars in Iraq and Afghanistan. A new study that models how shock waves pass through the he
It is the hardest everyday material on Earth, so why does diamond glisten when rubbed against another diamond? Now, the ancient but mysterious process of diamond grinding may have been explained by physicists in Germany, who have created a model fo
According to some, nanotechnology holds the promise of a future heaven on Earth: all Man's needs will be met and an idyllic paradise will ensue driven by wondrous machines the size of molecules. Others predict a hell of unprecedented proportions. Li

A team of Spanish astronomers claim they've discovered evidence of a significant object on the outskirts of the solar system. The object is so big it may have large satellites orbiting it. Officially it's named "G1.9." What the team believes it h
