Scientists identify new brain circuit in mice that controls body's inflammatory reactions

01/05/2024
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.

A 'cosmic glitch' in gravity

01/05/2024
Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale.

Biomarkers in blood to predict liver cancer

01/05/2024
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.

Social-media break has huge impact on young women's body image, study finds

01/05/2024
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.

Understanding youth nicotine use to prevent initiation and escalation

01/05/2024
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.

Why you can taste more ethanol in a cold pint of beer or warm glass of baijiu

01/05/2024
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.

Cell contractions drive the initial shaping of human embryos

01/05/2024
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).

New mRNA cancer vaccine triggers fierce immune response to fight malignant brain tumor

01/05/2024
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.

Father's gut microbes affect the next generation

01/05/2024
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 identify causal genetic variant linked to common childhood obesity

01/05/2024
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.

Scientists work out the effects of exercise at the cellular level

01/05/2024
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.

Nutrient research reveals pathway for treating brain disorders

01/05/2024
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.

Losing keys and everyday items 'not always sign of poor memory'

01/05/2024
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.

Virtual reality environment for teens may offer an accessible, affordable way to reduce stress

01/05/2024
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.

Clogged arteries worsened by cells that behave like cancer cells

01/05/2024
Researchers have found that cells inside clogged arteries have cancer-like properties that aggravate atherosclerosis, and anticancer drugs could be a new treatment.

Life expectancy in two disadvantaged areas higher than expected

01/05/2024
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.

Calcium can protect potato plants from bacterial wilt

01/05/2024
Scientists have discovered that calcium plays a significant role in enhancing the resistance of potato plants to bacterial wilt.

Earth-like environment likely on ancient Mars

01/05/2024
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 during the perimenopause

01/05/2024
Women are 40% more likely to experience depression in the perimenopause than those who aren't experiencing any menopausal symptoms, finds a new study.

Every breath you take: Study models the journey of inhaled plastic particle pollution

01/05/2024
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.
