With the growth of wind and solar energy and the increasing popularity of electric vehicles, many people in the U.S. may have forgotten about the promised “hydrogen economy.” But in research labs around the world, progress continues. Now scientists are reporting in the Journal of the American Chemical Society a new process that could help us move faster toward sustainable hydrogen-based energy.
Yale Univ. scientists may have cracked a part of the chemical code for one of the most basic, yet mysterious, processes in the natural world: nature’s ability to transform nitrogen from the air into usable nitrogen compounds. The process is called nitrogen fixation, and it occurs in microorganisms on the roots of plants. This is how nature makes its own fertilizers to feed plants, which feed us.
Liquid crystals are familiar to most of us as the somewhat humdrum stuff used to make computer displays and TVs. Even for scientists, it has not been easy to find other ways of using them. Now a group of researchers at the Univ. of Chicago is putting liquid crystals to work in a completely unexpected realm: as detectors for the protein fibers implicated in the development of neuro-degenerative diseases such as Alzheimer's.
Just as in the well-known children's story of Goldilocks and the Three Bears, something good happens when things are done in moderation, rather than in extremes. Now a new study has translated "not too hot or too cold, just right" to the quantum world and the generation of quantum entanglement and suggests that the universe started "neither too fast nor too slow."
Led by the inventor of the lithium-ion battery, a team of researchers in the Cockrell School of Engineering at The Univ. of Texas at Austin has identified a new safe and sustainable cathode material for low-cost sodium-ion batteries.
Emissions from the combustion of fossil fuels like coal, petroleum and natural gas tend to collect within Earth's atmosphere as "greenhouse gases" that are blamed for escalating global warming.
Imagine a "smart pill" that can sense problems in your intestines and actively release the appropriate drugs. We have the biological understanding to create such a device, but we're still searching for electronic materials (like batteries and circuits) that pose no risk if they get stuck in our bodies.
When you visit a Website, you often find yourself waiting and waiting for advertisements to load. Video starts playing automatically, and animated ads jump in front of what you were there to see. The seconds tick by. It doesn't have to be this way.
Tufts University biomedical engineers are using low-energy, ultrafast laser technology to make high-resolution, 3-D structures in silk protein hydrogels.
Some six million people in the U.S. suffer from scoliosis, a sideways curvature of the spine.
The world’s first entirely light-based memory chip to store data permanently has been developed by material scientists at Oxford University and University of Münster in collaboration with scientists at Karlsruhe and Exeter.
In China's factories, the robots are rising.
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have been awarded up to nearly $6 million from the Bill & Melinda Gates Foundation to develop a revolutionary HIV/AIDS alternative vaccine that has demonstrated great potential in animal models.
Like an aura, a personal microbial cloud surrounds your body. A dash of particles from your breath and a helping from your skin, among other sources, coalesce to make something unique, an imprint of you.
Researchers have discovered a new stretchable, transparent conductor that can be folded or stretched and released, resulting in a large curvature or a significant strain, at least 10,000 times without showing signs of fatigue. This is a crucial step in creating a new generation of foldable electronics—think a flat-screen television that can be rolled up for easy portability—and implantable medical devices
