Stanford researchers produce short-term reversal of skin aging in mice

December 5, 2007

Researchers at the Stanford University School of Medicine have reversed the effects of aging on the skin of mice, at least for a short period, by blocking the action of a single critical protein, NF-kappa-B.

After two weeks, the skin of 2-year-old mice had the same genes active as cells in the skin of newborn mice.

The work backs up the theory that aging is the result of… read more

Stanford researchers unmask proteins in telomerase, which enables cancer

March 20, 2008

Stanford University School of Medicine researchers and their colleagues have identified two new proteins that make up the telomerase complex–the protein conglomerate that maintains cells’ genetic material–providing potential new targets for cancer treatments.

Studying telomerase has been difficult because it’s available only in small quantities and no technology was sensitive enough to detect it at minute levels.

To get around the quantity problem, the researchers chopped it into… read more

Stanford scientists fit light-emitting bioprobe in a living cell

Light-based probes can be inserted without damage to the cell, could have profound impact on biological research

The beam structure alternates between layers of gallium arsenide and photonic crystal containing the light-producing quantum dots. (Photo credit: Gary Shambat, Stanford School of Engineering)

Stanford engineers have developed a new class of biophotonic (light-emitting) probes small enough to be injected into individual cells for intracellular sensing and control, without harm to the host.

The researchers call their device a “nanobeam,” because it resembles a steel I-beam with a series of round holes etched through the center. This beam, however, is not massive, but measures only a few microns in length and… read more

Stanford scientists make major breakthrough in regenerative medicine

April 25, 2007

Findings described in a new study by Stanford scientists may be the first step toward a major revolution in human regenerative medicine — a future where advanced organ damage can be repaired by the body itself.

In the May 2007 issue of The FASEB Journal, researchers show that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process… read more

Stanford software engineering MOOC aims at future startup CEOs

Instructors hope to provide people worldwide with crucial skills for starting their own companies

Vijay Pande, professor of chemistry at Stanford and colleague, Balaji Srinivasan, both with strong research and entrepreneurial backgrounds, taught a traditional classroom course in software engineering winter quarter aimed at future chief technology officers.

It was so successful they’re now going to go virtual, and starting June 17 they will begin teaching a 10-week massive open online course titled Startup Engineering. The idea is to reach thousands… read more

Stanford study first to analyze individual’s genome for risk of diseases, responses to treatment

April 30, 2010

For the first time, researchers have used a healthy person’s complete genome sequence to predict his risk for dozens of diseases and how he will respond to several common medications.

The risk analysis, from the Stanford University School of Medicine, also incorporates more-traditional information such as a patient’s age and gender and other clinical measurements.

The resulting, easy-to-use, cumulative risk report will likely catapult the use of such… read more

Stanford University’s president predicts the death of the lecture hall as university education moves online

Stanford University recently explored offering online courses to a larger audience with a programming class for iPhone applications, first available in 2009, that has been downloaded more than one million times.

This past fall, more than 100 000 students around the world took three engineering classes — Machine Learning, Introduction to Artificial Intelligence, and Introduction to Databases.

Stanford president John L. Hennessy says that’s just the beginning. In fact,… read more

Stanford’s ‘autonomous’ helicopters teach themselves to fly

September 2, 2008

Stanford computer scientists have developed an AI system that enables robotic helicopters to teach themselves to fly difficult stunts by watching other helicopters perform the same maneuvers.

The result is an autonomous helicopter than can perform a complete airshow of complex tricks on its own.

There is interest in using autonomous helicopters to search for land mines in war-torn areas or to map out the hot spots of… read more

Stanford’s popular free iPhone and iPad apps online course opens June 25 with a new feature: help and inspiration 24×7 via Piazza, a peer-to-peer social learning site — a first for Stanford online courses and on iTunes U.

Whazzit: your questions are answered by course instructors (“course captains”) and by fellow online learners.

When: June 25 to Aug. 27. Registration opens June 19 and ends July 6.… read more

Stanford’s New Driverless Car

June 18, 2007

A computer-controlled car named Junior is Stanford University’s official entry in the DARPA Urban Challenge, a race in which an autonomous car must navigate city streets, obey traffic laws, avoid obstructions, and, crucially, drive well among other cars in traffic.

Cue the Jaws theme music….

Stanford marine biologists have launched the ”Wave Glider” robot, which probing the Pacific Ocean off the California coast to provide researchers with near real-time data of sharks and other animals.

The Blue Serengeti Initiative, as the effort is called, picks up where the decade-long Tagging of Pacific Predators (TOPP) project left off. TOPP, an international collaboration among 75 scientists, involved tagging thousands of… read more

Stanford’s robotic Audi to brave Pikes Peak without a driver

February 4, 2010

A team of researchers at the Center for Automotive Research at Stanford (CARS) plans to race an autonomous vehicle up the 14,000-foot Pikes Peak without a driver at race speeds, something never done before.

The Audi TTS, nicknamed Shelley, knows exactly where she is on the road by using a differential GPS. Unlike a standard GPS system, hers corrects for interference in the atmosphere, showing the cars position on… read more

Star crust is 10 billion times stronger than steel

April 15, 2009

The crust of neutron stars is 10 billion times stronger than steel, according to new simulations by Los Alamos National Laboratory. That makes the surface of these ultra-dense stars tough enough to support long-lived bulges that could produce gravitational waves detectable by experiments on Earth.

Astronomers think they have seen a star being ripped to pieces by a previously unknown black hole (see ‘The awakening of a cosmic monster‘), says Nature News.

The astronomers saw a pulse of X-rays that rose and fell in intensity every 200 seconds. The team thinks that the oscillation is coming from the last bits of the star, which are making their final orbits before being sucked… read more
