The study, conducted in mice, is the first to show that creatine uptake is critical to the anti-tumor activities of killer T cells, the foot soldiers of the immune system.

Scientists have conducted an in-depth study on how carbon nanotubes with oxygen-containing groups can be used to greatly enhance the performance of perovskite solar cells. The newly discovered self-recrystallization ability of perovskite could lead to improvement of low-cost and efficient perovskite solar cells.

Called LOGAN, the deep neural network, i.e., a machine of sorts, can learn to transform the shapes of two different objects, for example, a chair and a table, in a natural way, without seeing any paired transforms between the shapes.

Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature. Instead, they isolate assemblies of neurons that play an essential role in long-term memory formation.

Consuming potato puree during prolonged exercise works just as well as a commercial carbohydrate gel in sustaining blood glucose levels and boosting performance in trained athletes, scientists report.

A single dose of a highly diluted VSV-Ebola virus (EBOV) vaccine -- approximately one-millionth of what is in the vaccine being used to help control the ongoing Ebola outbreak in the Democratic Republic of the Congo -- remains fully protective against disease in experimentally infected monkeys, according to scientists. The investigators completed the dosage study using cynomolgus macaques and an...

Scientists are developing powerful new devices and technologies to monitor and regulate brain activity. To ensure NIH keeps pace with rapid technological development and help clinicians and researchers ethically fit these new tools into practice, a new article highlights potential issues around and offers recommendations about clinical research with both invasive and noninvasive neural devices.

Researchers discover a new principle -- how cells protect themselves from mitochondrial defects.

Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. Chinese scientists have manufactured fibrous electrodes for wearable devices that are flexible and excel by their high energy density. A microfluidic technology was key for the preparation of the electrode material was a...

Researchers find genes that help maintain the 50-50 balance between male and female offspring in mice -- and that have major implications for male infertility.

The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness.

Scientists have found a new compound of plutonium with an unexpected, pentavalent oxidation state. This new phase of plutonium is solid and stable, and may be a transient phase in radioactive waste repositories.

A research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics - of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure.

An easy-to-use electrode set can assess sleep bruxism severity as well as a conventional polysomnography, a new study shows.

The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may be associated with the increased prevalence, in Western countries,...

Researchers have discovered an enzyme they believe could be key to preventing Group A Streptococcus infections that cause more than 500,000 deaths worldwide each year. The enzyme works through a novel mechanism of action that can also be found in other streptococcal species, increasing the impact and relevance of this finding.

Astronomers exposed acetylene ice -- a chemical that is used on Earth in welding torches and exists at Titan's equatorial regions -- at low temperatures to proxies of high-energy galactic cosmic rays.

Engineering biology is transforming technology and science. Researchers outline the technological advances needed to secure a safe, responsible future.

Researchers provide clearer picture of how lungs develop and discover novel markers to differentiate populations of lung cells implicated in lung diseases of premature babies.

A research team paved a way to achieve unexplored III-V semiconductor nanostructures. They grew branched GaAs nanowires with a nontoxic Bi element employing characteristic structural modifications correlated with metallic droplets, as well as crystalline defects and orientations. The finding provides a rational design concept for the creation of semiconductor nanostructures with the concentration...

A compound effective in killing chemotherapy-resistant glioblastoma-initiating cells (GICs) has been identified, raising hopes of producing drugs capable of eradicating refractory tumors with low toxicity.

The art of croissant making has inspired researchers to find a solution to a sustainable energy problem.

Exercising before eating breakfast burns more fat, improves how the body responds to insulin and lowers people's risk of type 2 diabetes and cardiovascular disease.

The first complete genetic sequences of individual mountain lions point the way to better conservation strategies for saving threatened populations of the wild animals.
