Efficiently mass-producing hydrogen from water is closer to becoming a reality thanks to new findings.

New research reveals that bacteria have internal clocks that align with the 24-hour cycle of life on Earth.

Researchers have discovered immune cells resident in the lungs that persist long after a bout of flu. Experiments with mice have shown that these helper cells improve the immune response to reinfection by a different strain of the flu virus. The discovery could yield approaches to developing longer-lasting vaccinations against quickly-mutating viruses.

Researchers have for the first time identified the way viruses like the poliovirus and the common cold virus 'package up' their genetic code, allowing them to infect cells. The findings open up the possibility that drugs or anti-viral agents can be developed that would stop such infections.

Researchers are working to develop a single-dose vaccine for SARS-CoV-2 that could potentially be stored at room temperature.

Currently there's no treatment for botulism once the toxin gets into neurons. This novel treatment neutralized the toxin with a second, modified botulinum toxin that delivered a mini antibody into the cells - reversing paralysis in mice.

More than half of people who use medical marijuana products to ease pain also experience clusters of multiple withdrawal symptoms when they're between uses, a new study finds. And about 10% of the patients taking part in the study experienced worsening changes to their sleep, mood, mental state, energy and appetite over the next two years as they continued to use cannabis.

Recent work pinpoints critical changes in an enzyme known as DICER, which create a cascade of effects on this microRNAome. The team identified primary actors circ2082, a circular RNA, and RBM3, an RNA-binding protein, which form a complex with DICER to trap it in the nucleus of glioblastoma cells, therefore disrupting the cytoplasmic microRNAome.

A new discovery finds that jellyfish create a 'ground effect,' similar to how air squeezes between an airplane and ground during take-off, which builds pressure and a force that boosts performance. Never before has it been proven that an animal can create this phenomenon away from a solid boundary, let alone the open ocean.

In a new study, researchers have described a medical device that might help with weight loss and requires a simpler operative procedure for implantation.

In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA's Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning it emits regular pulses of light.

Neuroscientists show that the entire auditory pathway represents sounds according to prior expectations.

Plant researchers have investigated the transport of compounds in maize. They focused on the mechanism used to transport the products of photosynthesis for further distribution in the plant through its phloem loading pathways. They describe how this mechanism has potentially created a special evolutionary advantage for maize.

Researchers have developed a nanoparticle vaccine that elicits a virus-neutralizing antibody response in mice after only a single dose.

In a new study, researchers show that microbes are capable of an incredible feat that could help reclaim a valuable natural resource and soak up toxic pollutants.

Scientists have discovered a new way to control the immune system's 'natural killer' (NK) cells, a finding with implications for novel cell therapies and tissue implants that can evade immune rejection. The findings could also be used to enhance the ability of cancer immunotherapies to detect and destroy lurking tumors.

Scientists have engineered a coloring technique, known as NeuroPAL (a Neuronal Polychromatic Atlas of Landmarks), which makes it possible to identify every single neuron in the brain of a worm.

Researchers find more similarities between the thylacine and wolf.

A team finds ways to control the surface texture of nanostructures.

In work that could help unravel the origin of sleep, an international team of researchers has shown that tiny, water-dwelling hydras not only show signs of a sleep-like state despite lacking central nervous systems but also respond to molecules associated with sleep in more evolved animals. The new results suggest that many sleep-related mechanisms developed before the brain and may have been...

Scientists have figured out a cheaper, more efficient way to conduct a chemical reaction at the heart of many biological processes, which may lead to better ways to create biofuels from plants.

Religious people facing life crises rely on emotion-regulation strategies that psychologists also use, a new study finds. They look for positive ways of thinking about hardship, a practice known to psychologists as 'cognitive reappraisal.' They also tend to have confidence in their ability to cope with difficulty, a trait called 'coping self-efficacy.' Both have been shown to reduce symptoms of...

Transmitting sensory signals from prostheses to the nervous system helps leg amputees to perceive prosthesis as part of their body. While amputees generally perceive their prostheses as heavy, this feedback helps them to perceive the prostheses as significantly lighter, researchers have shown.

An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, researchers have shown how new genes that produce resistance can arise from completely random DNA sequences.
