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.

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).

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.

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.

The body clock has a significant impact on the performance of NBA players. Data shows vastly better win ratio for home teams from the Western Time Zone Area (PDT) when playing an EDT team, compared to vice versa.

Researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This discovery provides valuable insights into underlying causes of spermatogenic failure, the major contributor to male infertility. Furthermore, unlike other typical Heat Shock Factors, which primarily regulate gene expression in response to stress, such as heat shock, HSF5 plays a specific role in male germ production during meiosis under non-stress conditions.

A simple blood test could allow doctors to determine whether a person may be at higher risk for stroke or cognitive decline during their lifetime, according to a new study.

When adults became angry after remembering past experiences, the function of cells lining the blood vessels was negatively impaired, which may restrict blood flow, according to a new study. Previous research has found that this may increase the risk of heart disease and stroke. In this study, episodes of anxiety and sadness did not trigger the same change in functioning of the blood vessel lining.

In an effort to improve delivery of costly medical treatments, a team of researchers in electrical engineering has developed a stimulating method that could make the human body more receptive to certain gene therapies.

Researchers have discovered that the enzyme cyclophilin A, which is produced in large amounts in hematopoietic stem cells, is key for these cells to retain their regenerative potential and avert the effects of aging via an unexpected mechanism.

A research team embarked on a quest to understand the diversity and cellular mechanisms of human Th2 cells. By conducting gene expression analyses of inflamed tissues, they pinpointed a subset of Th2 cells called Th2-MPP cells. Their findings suggested that these cells might serve as precursors to several crucial Th2 cell populations responsible for disease symptoms. These discoveries lay the groundwork for therapeutic interventions targeting these cells, potentially offering relief to patients living with allergic diseases.

Loneliness in adulthood follows a U-shaped pattern: it's higher in younger and older adulthood, and lowest during middle adulthood, reports a new study that examined nine longitudinal studies from around the world. The study also identified several risk factors for heightened loneliness across the whole lifespan, including social isolation, education and physical impairment.
