Researchers have, for the first time, used a material's persistent photoconductivity to stimulate neurotype cells. The technique, which is relatively simple, should facilitate future research on using charge to influence cellular behavior.
It's a popular tradition to throw coins into fountains in the hopes of having wishes granted. But what would happen if you could "throw" electrons into the water instead? That is, what happens shortly after an electron is injected into water?
Advancements in a fuel cell technology powered by solid carbon could make electricity generation from resources such as coal and biomass cleaner and more efficient, according to a new paper published by Idaho National Laboratory researchers.
When John Wesley Hyatt patented the first industrial plastic in 1869, his intention was to create an alternative to the elephant tusk ivory used to make piano keys. But this early plastic also sparked a revolution in the way people thought about manufacturing: What if we weren't limited to the materials nature had to offer?
Researchers at Pacific Northwest National Laboratory (PNNL) have developed a self-healing cement that could repair itself in as little as a few hours. Wellbore cement for geothermal applications has a life-span of only 30 to 40 years. Show More Summary
Fuel cells are a key future energy technology emerging as eco-friendly and renewable energy sources. In particular, solid oxide fuel cells composed of ceramic materials can directly convert fuels such as biomass, LNG, and LPG to electric energy. Show More Summary
Doctors have long treated heart attacks, improved asthma symptoms, and cured impotence by increasing levels of a single molecule in the body: nitric oxide.
Scientists from the U.S. Army Research Laboratory and the Lawrence Livermore National Laboratory found a solution to a significant challenge in making high-energy explosives. They safely improved the overall chemical yield derived from diaminoglyoxime, known as DAG, and significantly increased the amount of material made per reaction.
Lithium-sulfur batteries are promising candidates for replacing common lithium-ion batteries in electric vehicles since they are cheaper, weigh less, and can store nearly double the energy for the same mass. However, lithium-sulfur batteries become unstable over time, and their electrodes deteriorate, limiting widespread adoption.
The Joint Chemical Agent Detector (JCAD) has become an important defense tool on battlefields and in war-torn cities over the last few years. About the size and shape of a VHS tape or a hardcover bestselling novel, JCADs sound an alarm and begin to light up if nerve agents such as sarin or blister agents such as mustard gas are present.
When Lawrence Livermore scientist Tadashi Ogitsu leased a hydrogen fuel-cell car in 2017, he knew that his daily commute would change forever. There are no greenhouse gases that come out of the tailpipe, just a bit of water vapor.
Researchers from Texas A&M University report significant advances in their understanding and control of a chameleon-like material that could be key to next-generation computers that are even more powerful than today's silicon-based machines.
How can life originate before DNA and genes? One possibility is that there are natural processes that lead to the organisation of simple physical objects such as small microcapsules that undergo rudimentary forms of interaction, self-organisation and information processing.
Researchers at Purdue University just made high throughput screening, a process often used in drug discovery, 10 times faster than previous methods.
RNA was probably the first informational molecule. Now, chemists from Ludwig-Maximilians-Universitaet (LMU) in Munich have demonstrated that alternation of wet and dry conditions could have sufficed to drive the prebiotic synthesis of the RNA nucleosides found in all domains of life.
A group of scientists from the Siberian Federal University (SFU, Krasnoyarsk, Russia) and the Nikolaev Institute of Inorganic Chemistry (NIIC, Novosibirsk, Russia) have combined the useful properties of metal phthalocyanines and palladium membranes in order to create active layers in hydrogen detectors.

A University of Illinois and Mayo collaboration has demonstrated a novel gene expression analysis technique that can accurately measure levels of RNA quickly and directly from a cancerous tissue sample while preserving the spatial information across the tissue —something that conventional methods cannot do.

Many drugs work by inhibiting protein enzymes associated with a particular disease. Unfortunately, the same drugs can inhibit protein enzymes unrelated to the disease, resulting in harmful side effects. One potential solution is to better identify structural features that determine a protein enzyme's function.
A new study reveals the molecular structure of a protein called alpha(?)Klotho, and how it helps to transmit a hormonal signal that slows aging.
In an advance that could push cheap, ubiquitous solar power closer to reality, University of Michigan researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors.
