The brain can direct the immune system to an unexpected degree, capable of detecting, ramping up and tamping down inflammation, shows a new study in mice.

Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale.

Early detection has the potential to transform treatment and outcomes in cancer care, especially for cancers like liver cancer, which is typically diagnosed at a late stage with limited options for cure. A new study suggests that proteins detectable in the blood could improve predictions about risk of liver cancer years before typical diagnosis.

There's a large and growing body of evidence pointing to potentially negative impacts of social media on mental health, from its addictive nature to disruptions in sleep patterns to effects on body image. Now, a new study has found that young women who took a social media break for as little as one week had a significant boost in self-esteem and body image -- particularly those most vulnerable to thin-ideal internalization.

Using multiple nicotine products can be associated with higher levels of nicotine dependence among youth and increased mortality in adults, compared with the use of one product alone. Researchers have now uncovered factors that contribute to adolescents using multiple nicotine products. These findings, they say, will help inform efforts to prevent escalation from single to multiple product use.

We all have our own preferred drinking temperatures for different alcoholic beverages, with people commonly enjoying beer or white wine chilled, red wine near room temperature, or baijiu (Chinese whisky) or sake warmed. Now, researchers report that alcoholic beverages may taste more or less 'ethanol-like' at different temperatures, and this may be explained by how water and ethanol form either chain-like or pyramid-shaped clusters at the molecular level.

Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell adhesion in this phenomenon and pave the way for improved assisted reproductive technology (ART).

An mRNA cancer vaccine quickly reprogrammed the immune system to attack the most aggressive type of brain tumor in a first-ever human clinical trial.

Researchers changed the composition of the gut microbiota in male mice through common antibiotics, inducing a condition called dysbiosis, and found that: - Mouse pups sired by a dysbiotic father show significantly lower birth weight, and have increased risk of growth disorders and postnatal mortality.

Researchers have identified a causal genetic variant strongly associated with childhood obesity. The study provides new insight into the importance of the hypothalamus of the brain and its role in common childhood obesity and the target gene may serve as a druggable target for future therapeutic interventions.

The health benefits of exercise are well known but new research shows that the body's response to exercise is more complex and far-reaching than previously thought. In a study on rats, a team of scientists has found that physical activity causes many cellular and molecular changes in all 19 of the organs they studied in the animals.

The team discovered that an essential nutrient called choline is transported into the brain, across the blood-brain barrier, by a protein transporter called FLVCR2. This is discovery will inform future design of drugs for diseases such as Alzheimer's and stroke, mimicking choline so they can be smuggled into the brain.

The mysteries of how memory works are explained in a new book that suggests anyone can boost their powers of recall -- and that losing your keys is normal.

Working with teens, researchers designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 teens, researchers found that most of the teens used the technology about twice a week without being prompted and reported lower stress levels after using the environment.

Researchers have found that cells inside clogged arteries have cancer-like properties that aggravate atherosclerosis, and anticancer drugs could be a new treatment.

Better than expected life expectancy in two disadvantaged areas in England is probably due to population change according to local residents and professionals. In the UK, people from the most disadvantaged areas can expect to die nine years earlier compared with people from the least disadvantaged areas while people in the north of England have lower life expectancy, higher infant mortality and worse health and wellbeing compared with national averages.

Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt.

A research team using the ChemCam instrument onboard NASA's Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, which indicates that the sediments were formed in a river, delta, or near the shoreline of an ancient lake.

Women are 40% more likely to experience depression in the perimenopause than those who aren't experiencing any menopausal symptoms, finds a new study.

With recent studies having established the presence of nano and microplastic particles in the respiratory systems of both human and bird populations, new research has modeled what happens when people breathe in different kinds of plastic particles and where they end up.
