The cellular nutrient glutamine launches a metabolic signaling pathway that promotes the function of some immune system T cells and suppresses others, Vanderbilt researchers have discovered.
In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun's energy through "water splitting," an artificial photosynthesis technique that uses sunlight to generate hydrogen ...
Hydrogen fuel cells offer an attractive source of continuous energy for remote applications, from spacecraft to remote weather stations. Fuel cell efficiency decreases as the Nafion membrane, used to separate the anode and ...
One factor holding back the widespread use of eco-friendly hydrogen fuel cells in cars, trucks and other vehicles is the cost of the platinum catalysts that make the cells work. One approach to using less precious platinum ...
In recent years, renewable energy has been on the rise in the United States. Still, the overwhelming majority of our energy comes from fossil fuels. And, renewable energy needs to overcome significant limitations and obstacles ...
Sandia National Laboratories helped design the first generation of fueling stations for hydrogen-powered cars so that they're as safe as conventional gas stations. Now, Sandia is working to do the same for the next generation ...
A recent study affiliated with UNIST has introduced a novel catalyst that can significantly enhance the performance of perovskite electrodes in Solid Oxide Fuel Cell (SOFC).
In studies of mouse cells, Johns Hopkins researchers have found that low levels of cellular copper appear to make fat cells fatter by altering how cells process their main metabolic fuels, such as fat and sugar.
A bacterium named Moorella thermoacetica won't work for free. But UC Berkeley researchers have figured out it has an appetite for gold. And in exchange for this special treat, the bacterium has revealed a more efficient path ...
Fuel cells have long been viewed as a promising power source. These devices, invented in the 1830s, generate electricity directly from chemicals, such as hydrogen and oxygen, and produce only water vapor as emissions. But ...
