Researchers have created an inhalable COVID-19 vaccine that is shelf stable at room temperature for up to three months, targets the lungs specifically and effectively, and allows for self-administration via an inhaler.

A new study measures changes in the human brain's response to a perceived threat following non-invasive stimulation of the nervous system via the vagus nerve. The results have implications for the development of treatments for post-traumatic stress disorder (PTSD) and other mental health conditions, as well as for increasing alertness and attention during learning.

The deepwater sculpin is not an attractive fish by any conventional standard. You won't find it hanging on a plaque or landing a feature role in a Disney movie. What you might say about the bottom-dweller is that it's a survivor, having managed to eke out an existence at the bottom of Canada's deepest and coldest lakes since the last ice age. Researchers are now sequencing its entire genome to see...

More than eight out of 10 British people who are seeking support for having lost a loved one to COVID-19 reported alarming Post Traumatic Stress Disorder symptoms, new research has found.

Researchers have developed a nanosheet-laminated photocatalytic membrane that demonstrates both excellent water permeance and photocatalytic activity. The membrane's photocatalytic properties make it easier to clean as irradiating the membrane with light successfully reduces fouling. This revolutionary membrane technology can be applied to water purification, and thus has the potential to...

New research suggests that the historical emergence of cultivated rice from wild rice plants resulted from a combination of three gene mutations that make the seeds (i.e., the grains of rice) fall from the plant less easily. These results not only shed light on early history but will hopefully contribute towards the development of more efficient rice cultivars in the future.

Scientists have taken a promising step towards a new generation of accurate, affordable and portable devices to detect concussion, epilepsy and dementia.

A simple and versatile nanoparticle ink could help next-generation perovskite solar cells to be printed at scale and become the dominant force in commercial photovoltaics.

A newly discovered star only takes four years to travel around the black hole at the center of our galaxy.

A new study describes the immune response triggered by COVID-19 infection that damages the brain's blood vessels and may lead to short- and long-term neurological symptoms. The study examined brain changes in nine people who died suddenly after contracting the virus.

Camelina, an oilseed plant grown in modern-day Ukraine, may have been a more important and widespread crop than previously thought. New findings could inform breeding programs to improve this crop for biofuels applications.

Researchers created atomic-level models of the spike protein that plays a key role in COVID-19 infection and immunity, revealing how the protein bends and moves as it seeks to engage receptors.

The latest omicron subvariants -- especially the currently dominant BA.4 and BA.5 forms -- are even better at eluding vaccines and most treatments, researchers have found.

Researchers found that in mice how much they ate and when altered the nature of their gut microbiome: too much food too frequently resulted in poorer microbial and metabolic health.

Eating one avocado a day for six months was found to have no effect on belly fat, liver fat or waist circumference in people with overweight or obesity, according to a new study. However, it did lead to a slight decrease in unhealthy cholesterol levels.

The gene defect underlying Krabbe disease causes degeneration of neurons directly, independent of its effects on other cell types, according to a new study. The discovery represents a new mechanism of action for the mutant gene, presenting a more accurate picture of the disease process that may help in the development of therapies.

Medical researchers find an answer to the mystery of why most human embryos die young.

In a new finding that goes against current conservation paradigms, re-introducing wolves and other predators to our landscapes does not miraculously reduce deer populations, restore degraded ecosystems or significantly threaten livestock, according to a new study.

A white mineral ring as tall as the Statue of Liberty creeps up the steep shoreline of Lake Mead, a Colorado River reservoir just east of Las Vegas on the Nevada-Arizona border. It is the country's largest reservoir, and it's draining rapidly.

A global research effort has assessed two promising technologies to remove carbon dioxide from the atmosphere. While still in the early stages of development, direct air carbon capture and sequestration (DAC) -- together with other carbon dioxide removal strategies -- are considered critical to achieving a net-zero greenhouse gas emissions economy by 2050 and limiting global warming to less than...

Robotic ammonites, evaluated in a university pool, allow researchers to explore questions about how shell shapes affected swimming ability. They found trade-offs between stability in the water and maneuverability, suggesting that the evolution of ammonite shells explored different designs for different advantages, rather than converged toward a single best design.

Researchers definitively linked the function of a specific domain of proteins important in plant-microbe biology to a cancer trigger in humans, knowledge that had eluded scientists for decades.

The ideal method of determining what type of cancer mutation a patient has is to compare two samples from the same patient, one from the tumor and one from healthy tissue. Such tests can be complicated and costly, however, so researchers hit upon another idea -- using massive public DNA databases to look for common cell mutations that tend to be benign, so that researchers can identify rarer...

A study has identified a molecule -- the purine inosine -- that boosts fat burning in brown adipocytes. The mechanism was discovered in mice, but probably exists in humans as well: If a transporter for inosine is less active, the mice remain significantly leaner despite a high-fat diet.
