Argonne National Laboratory released a study that shows gasoline and diesel refined from Canadian oil sands have a higher carbon impact than fuels derived from conventional domestic crude sources. The research, which was conducted in collaboration with Stanford Univ. and the Univ. of California at Davis, shows variability in the increase of greenhouse gas impacts, depending on the type of extraction and refining methods.

One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs and stabilize energy prices involves converting the world's entire energy infrastructure to run on clean, renewable energy.
Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets.
Once messenger RNA (mRNA) has done its job—conveying the information to produce the proteins necessary for a cell to function—it is no longer required and is degraded. Scientists have long thought that the decay started after translation was complete and that decaying RNA molecules provided little biological information.
Stanford Univ. scientists have created a new carbon material that significantly boosts the performance of energy-storage technologies. Their results are featured in ACS Central Science. The new "designer carbon" is both versatile and controllable and represents a dramatic improvement over conventional activated carbon.
A new technique developed at Stanford Univ. harnesses the buzz of everyday human activity to map the interior of the Earth. Using tiny ground tremors generated by the rumble of cars and trucks across highways, the activities within offices and homes, pedestrians crossing the street and even airplanes flying overhead, a Stanford Univ. team created detailed three-dimensional subsurface maps of the California port city of Long Beach.
Stanford Univ. electrical engineer Jelena Vuckovic wants to make computers faster and more efficient by reinventing how they send data back and forth between chips, where the work is done. In computers today, data is pushed through wires as a stream of electrons. That takes a lot of power, which helps explain why laptops get so warm.
Stanford Univ. scientists have solved a long-standing mystery about methanogens, unique microorganisms that transform electricity and carbon dioxide into methane. In a new study, the Stanford team demonstrates for the first time how methanogens obtain electrons from solid surfaces. The discovery could help scientists design electrodes for microbial "factories" that produce methane gas and other compounds sustainably.
Researchers studying how the brain makes decisions have, for the first time, recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. The findings result from experiments led by electrical engineering Prof. Krishna Shenoy, whose Stanford Univ. lab focuses on movement control and neural prostheses controlled by the user's brain.
To design the next generation of optical devices, ranging from efficient solar panels to LEDs to optical transistors, engineers will need a 3-D image depicting how light interacts with these objects on the nanoscale. Unfortunately, the physics of light has thrown up a roadblock in traditional imaging techniques: The smaller the object, the lower the image's resolution in 3-D.
Stanford Univ. scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today.
Computer chips, solar cells and other electronic devices have traditionally been based on silicon, the most famous of the semiconductors, that special class of materials whose unique electronic properties can be manipulated to turn electricity on and off the way faucets control the flow of water. There are other semiconductors. Gallium arsenide is one such material and it has certain technical advantages over silicon.
A puzzling observation, pursued through hundreds of experiments, has led Stanford Univ. researchers to a simple yet profound discovery: Under certain circumstances, droplets of fluid will move like performers in a dance choreographed by molecular physics.
A protein found in pancreatic tumors may lead to a new chemotherapy that is effective against many different kinds of cancers, but turning the discovery into a new drug has required a bit of chemistry know-how.
Three years ago, Sohan Dharmaraja was a Stanford Univ. engineering doctoral candidate in search of his next project when he visited the Stanford Office of Accessible Education, which helps blind and visually challenged students successfully navigate the world of higher education.
A technology developed by Stanford Univ. scientists for passively probing the seafloor using weak seismic waves generated by the ocean could revolutionize offshore oil and natural gas extraction by providing real-time monitoring of the subsurface while lessening the impact on marine life.
Stacking perovskites, a crystalline material, onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford Univ. scientists. The researchers describe their novel perovskite-silicon solar cell in Energy & Environmental Science.
Many of today's most promising renewable energy technologies rely upon catalysts to expedite the chemical reactions at the heart of their potential. Catalysts are materials that enhance chemical reactions without being consumed in the process. For over a century, engineers across the world have engaged in a near-continual search for ways to improve catalysts for their devices and processes.

Though scientists don’t completely understand what triggers solar flares, Stanford Univ. solar physicists Monica Bobra and Sebastien Couvidat have automated the analysis of those gigantic explosions. The method could someday provide advance warning to protect power grids and communication satellites.
The economic damage caused by a ton of carbon dioxide emissions could be six times higher than the value that the U.S. now uses to guide current energy regulations, and possibly future mitigation policies, Stanford Univ. scientists say. A recent U.S. government study concluded, based on the results of three widely used economic impact models, an additional ton of carbon dioxide emitted in 2015 would cause $37 worth of economic damages.
Around 400 BC, Hippocrates was among the first people in recorded history to postulate the brain as the seat of sensation and intelligence. Yet only in the last 100 years have we identified, and closely studied, its key building block: the neuron. A highly specialized cell found in all but the simplest animals, like sponges, the neuron is one of the keys to understanding the brain.
For decades, the mantra of electronics has been smaller, faster, cheaper. Today, Stanford Univ. engineers add a fourth word: taller. A Stanford team revealed how to build high-rise chips that could leapfrog the performance of the single-story logic and memory chips on today's circuit cards.

Stanford Univ. engineers have designed and built a prism-like device that can split a beam of light into different colors and bend the light at right angles, a development that could eventually lead to computers that use optics, rather than electricity, to carry data.
Stanford Univ. engineers have invented a revolutionary coating material that can help cool buildings, even on sunny days, by radiating heat away from the buildings and sending it directly into space. The heart of the invention is an ultra-thin, multi-layered material that deals with light, both invisible and visible, in a new way.
