SLAC National Accelerator Laboratory and Stanford University scientists have set a world record for energy storage, using a clever "yolk-shell" design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is possible with today's commercial technology.
Stanford University researchers, in collaboration with NASA's Jet Propulsion Laboratory and the Massachusetts Institute of Technology, have designed a robotic platform that could take space exploration to new heights. The mission proposed for the platform involves a mother spacecraft deploying one or several spiked, roughly spherical rovers to the Martian moon Phobos.
A team of researchers, led by Lawrence Livermore National Laboratory, has answered a longstanding, much debated question in condensed matter physics. The question had to do with the rare earth element cerium (Ce), which undergoes a surprising, large isostructural volume collapse at high pressure.
A microscale technique known as optical trapping uses beams of light as tweezers to hold and manipulate tiny particles. Stanford University researchers have found a new way to trap particles smaller than 10 nm, which until now have escaped light's grasp.
Stanford University scientists have developed a new technique for watching blood flow in living animals. The technique involves carbon nanotubes and lasers, and will allow researchers to better study arterial diseases and therapies.
Coating the surface of a material with a single layer of diamond-like crystals greatly improves images of it taken with an electron microscope, according to a study led by scientists at SLAC National Accelerator Laboratory and Stanford University. In results, the group reported a nearly three-fold improvement in the quality of photoelectron emission microscope images when they used the coating.
Stanford University researchers have designed the fastest, most accurate algorithm yet for brain-implantable prosthetic systems that can help disabled people maneuver computer cursors with their thoughts. The algorithm's speed, accuracy, and natural movement approach those of a real arm, doubling performance of existing algorithms.
Quantum mechanics offers the potential to create absolutely secure telecommunications networks by harnessing a fundamental phenomenon of quantum particles. Now, a team of Stanford University physicists has demonstrated a crucial first step in creating a quantum telecommunications device that could be built and implemented using existing infrastructure.
A team led by SLAC National Accelerator Laboratory and Stanford University scientists has made an important discovery toward understanding how a large group of complex copper oxide materials lose their electrical resistance at remarkably high temperatures. The materials in question are high-temperature superconductors, which conduct electricity perfectly with no resistance when cooled below -100 C.
A team of Stanford University chemists and engineers has created the first synthetic material that is both sensitive to touch and capable of healing itself quickly and repeatedly at room temperature. The advance could lead to smarter prosthetics or resilient personal electronics that repair themselves.
Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today. Unlike rigid silicon solar panels that adorn many rooftops, Stanford's thin film prototype is made of carbon materials that can be coated from solution.
Predicted by Albert Einstein's general theory of relativity, the waves occur when massive celestial objects move and disrupt the fabric of space-time. But by the time these waves reach Earth, they are so weak that the planet expands and contracts less than an atom in response. No instrument or observatory has ever directly detected them. A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible.
If you were a bacterium, the virus M13 might seem innocuous enough. It insinuates more than it invades, setting up shop like a freeloading house guest, not a killer. Once inside it makes itself at home, eating your food, texting indiscriminately. Recently, however, bioengineers at Stanford University have given M13 a bit of a makeover; they have parasitized the parasite and harnessed M13's key attributes to create what might be termed as the biological Internet, or "Bi-Fi."
When the Dark Energy Camera opened its giant eye last week and began taking pictures of the ancient light from far-off galaxies, more than 120 members of the Dark Energy Survey eagerly awaited the first snapshots. Those images have now arrived.
Stanford University electrical engineers overturn existing models to demonstrate the feasibility of a millimeter-sized, wirelessly powered cardiac device. The findings, say the researchers, could dramatically alter the scale of medical devices implanted in the human body.
A collaboration between a Stanford University ant biologist and a computer scientist has revealed that the behavior of harvester ant as they forage for food mirrors the protocols that control traffic on the Internet.
Researchers at the Stanford University School of Medicine and Intel Corp. have collaborated to synthesize and study a grid-like array of short pieces of a disease-associated protein on silicon chips normally used in computer microprocessors. Used recently to identify patients with a severe form of lupus, the new technology has the potential to improve diagnoses of a multitude of diseases.
Lawrence Berkeley National Laboratory scientists have developed a way to send molecules and proteins across the cell wall of algae, a feat that opens the door for a new way to study and manipulate these tiny organisms. The research could advance the advance the development of algae-based biofuels, pharmaceuticals, and other useful compounds.
Tests performed at NIST show that a new method for splitting photon beams could overcome a fundamental physical hurdle in transmitting electronic data. The findings confirm that a prototype device developed with collaborators at Stanford University can double the amount of quantum information that can be sent readily through fiber-optic cables, and in theory could lead to an even greater increase in the rate of this type of transmission.
Most methane comes from natural gas, a fossil fuel. Stanford University and Penn State University scientists are taking a greener approach using microbes that can convert renewable electricity into carbon-neutral methane.
In a breakthrough effort for computational biology, the world's first complete computer model of an organism has been completed, Stanford University researchers report. A team led by Stanford bioengineering Professor Markus Covert used data from more than 900 scientific papers to account for every molecular interaction that takes place in the life cycle of Mycoplasma genitalium , the world's smallest free-living bacterium.
Using high-power X-ray imaging of an actual working battery, a Stanford University-SLAC National Accelerator Laboratory team discovered that sulfur particles in the cathode largely remain intact during discharge. Their results could help scientists find new way to develop commercially viable lithium-sulfur batteries for electric vehicles.

Stanford University researchers have invented an electrically conductive hydrogel that is quick and easy to make, can be patterned onto surfaces with an inkjet printer, and demonstrates unprecedented electrical performance. This combination of characteristics hold promise for biological sensors and futuristic energy storage devices.
Stanford University scientists have breathed new life into the nickel-iron battery, a rechargeable technology developed by Thomas Edison more than a century ago. The team has created an ultrafast nickel-iron battery that can be fully charged in about 2 min and discharge in less than 30 sec.
