A recent study published in the journal Nutrients found that vegan meals increased beneficial gastrointestinal hormones in individuals with obesity, type 2 diabetes, and healthy participants. This increase in gut hormones can help regulate blood sugar, enhance insulin secretion, promote satiety, and support weight management.
A study of people who grew up in the era of leaded gasoline found that higher blood lead levels at age 11 were associated with signs of mental illness and difficult personality traits by age 38. Participants exposed to higher levels of lead as children were rated as more neurotic, less agreeable, and less conscientious than their peers.

Scientists have identified natural antibodies within protein corona that trigger immune system response to nanoparticles. Depleting these antibodies reduces complement system activation, enabling safe delivery of cancer-fighting drugs and imaging agents.
Women taking HRT tablets are up to two times more likely to develop potentially life-threatening blood clots. The study found a higher risk for tablet treatments, particularly those containing horse urine-derived oestrogen, but no increased risk for patch, gel, or cream forms.
A large study published in The BMJ found that HRT tablets are associated with a higher risk of rare but serious blood clots, particularly those containing equine oestrogen. No increased risk was found for skin patches, gels and creams. The study provides important information for women and their doctors to make informed treatment choices.

By blocking this protein, females can no longer produce viable eggs, leading to the death of embryos. This discovery could lead to the development of new drugs as birth control for mosquito populations.
A new study found that ketogenic supplements can delay tonic-clonic seizures caused by high levels of oxygen, even in a normal diet. The supplements increased blood ketone levels, providing therapeutic ketosis and resistance to seizures.

Researchers found that ankylosaurs had a built-in air conditioner in their snouts, which was just as efficient as those in living animals. The long, twisty noses allowed for effective heat exchange and cooling of the brain.
A Marshall University study found significant differences in umbilical cord blood metal levels between urban and rural newborns. Copper and molybdenum were higher in urban samples, while no marked differences occurred for other elements. The study suggests a potential link between prenatal exposure to toxins and neonatal outcomes.
A Scottish study found that changing the legal drink-driving limit did not reduce road traffic accidents despite substantial initial public awareness campaigns. The researchers suggest inadequate enforcement and publicity as possible reasons for the lack of impact.
Researchers found that people who eat a diet rich in red meat have triple the TMAO levels of those who eat a diet rich in either white meat or mostly plant-based proteins. However, discontinuation of red meat eventually lowers these TMAO levels, suggesting a promising new strategy for individualizing diets and preventing heart disease.
