'Unzipped' Carbon Nanotubes Could Help Energize Fuel Cells And Batteries, Stanford Scientists Say
Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at Stanford University. Their findings are published in the May 27 online edition of the journal Nature Nanotechnology.
New Stanford Battery Shuts Down at High Temperatures And Restarts When It Cools
Stanford researchers have developed the first lithium-ion battery that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from recliners and computers to navigation systems and hoverboards.
Odds Are Good That Risky Gambling Choices Are Influenced by a Single Brain Connection
One person's risky bet is another's exciting opportunity. The difference between those outlooks comes down to more than just disposition: It turns out that people with a stronger connection between two brain regions have a more cautious financial outlook.
Flexible Gene Expression May Regulate Social Status in Male Fish
For a small African fish species, a colorful dominant male does better in life, winning access to food and females. New research by Stanford biologists suggests that this lucky outcome is regulated at a genetic level, by turning genes on and off.
Stanford Technology Makes Metal Wires on Solar Cells Nearly Invisible to Light
A solar cell is basically a semiconductor, which converts sunlight into electricity, sandwiched between metal contacts that carry the electrical current. But this widely used design has a flaw: The shiny metal on top of the cell actually reflects sunlight away from the semiconductor where electricity is produced, reducing the cell's efficiency.
Stanford Researcher Suggests Storing Solar Energy Underground for a Cloudy Day
A new study shows that wind, water and solar generators can theoretically result in a reliable, affordable national grid when the generators are combined with inexpensive storage.
Stanford Engineers Create Artificial Skin That Can Send Pressure Sensation to Brain Cell
Stanford engineers have created a plastic "skin" that can detect how hard it is being pressed and generate an electric signal to deliver this sensory input directly to a living brain cell.
Stanford Scientists Help Discover Pacific Bluefin Tunas' Favorite Feeding Spots
After chowing down a big meal, you might feel your belly warm as your stomach muscles and digestive organs set to work breaking your food into smaller and smaller pieces rich in nutrients. A bluefin tuna's stomach experiences a similar spike in temperature when it gulps down a mouthful of juicy sardines.
Stanford Team Re-engineers Virus to Deliver Therapies to Cells
Stanford researchers have ripped the guts out of a virus and totally redesigned its core to repurpose its infectious capabilities into a safe vehicle for delivering vaccines and therapies directly where they are needed. The study reported today in the Proceedings of the National Academy of Sciences breathes new life into the field of targeted delivery, the ongoing effort to fashion treatments that affect diseased areas but leave healthy tissue alone.
