Stanford researchers develop new technology for cheaper, more efficient solar cells

The sun provides more than enough energy for all our needs, if only we could harness it cheaply and efficiently. Solar energy could provide a clean alternative to fossil fuels, but the high cost of solar cells has been a major barrier to their wides...

Stanford researchers develop new wireless technology for faster, more efficient networks

"Wireless communication is a one-way street. Over." Radio traffic can flow in only one direction at a time on a specific frequency, hence the frequent use of "over" by pilots and air traffic controllers, walkie-talkie users and emergency perso...

The brain knows what the nose smells, but how? Stanford researchers...

Mice know fear. And they know to fear the scent of a predator. But how do their brains quickly figure out with a sniff that a cat is nearby? It's a complex process that starts with the scent being picked up by specific receptors in their no...

Need a study break to refresh? Maybe not, say Stanford researchers

It could happen to students cramming for exams, people working long hours or just about anyone burning the candle at both ends: Something tells you to take a break. Watch some TV. Have a candy bar. Goof off, tune out for a bit and come back to the t...

New artificial skin could make prosthetic limbs and robots more sensitive

The light, tickling tread of a pesky fly landing on your face may strike most of us as one of the most aggravating of life's small annoyances. But for scientists working to develop pressure sensors for artificial skin for use on prosthetic limbs ...

Researchers identify best hours for shut-eye when sleep must be limited

People getting a minimal amount of sleep do better if they go to bed early in the morning rather than late at night, suggests Stanford University Medical Center research. A recently published pilot study on the effects of sleep deprivation also found that individual tolerance of sleep restriction varies widely, yet study participants had a better overall adaptation to early morning sleep.

Bone marrow cells take on new role in the brain, say...

Researchers have published new evidence showing that cells from the bone marrow might help repair or maintain cells in other tissues. In a paper in this week's online edition of the Proceedings of the National Academy of Sciences, the researchers describe finding chromosomes from a bone marrow transplant in the brain cells of transplant recipients. When people receive a bone marrow transplant after high-dose chemotherapy, some of the transplanted cells regenerate the blood-making cells that were destroyed. In past experiments in mice, scientists found that cells from the transplant could also relocate to tissues throughout the body rather than being restricted to the bone marrow and blood.

New technique cuts risks of gene therapy

Stanford researchers have developed a technique that could cut the risks associated with gene therapy. Traditionally, gene therapy involves sneaking a snippet of genes into a person's DNA via a virus messenger. But the result is the new sequence gets randomly placed within the patient's existing genes, sometimes triggering other illnesses, such as leukemia. The new technique eliminates the need for a virus delivery system and places the genes in precise locations.

Researchers to test smallpox vaccine

Researchers in Northern California are conducting a clinical trial that will test whether diluted doses of the smallpox vaccine produce adequate immunity in adults who have previously been vaccinated. The results of the federally funded study, for which volunteers are now being sought, will help shape U.S. policy on how the vaccine would be given in the event of a smallpox outbreak.
