Job demand, not just skills, shapes public attitudes on immigration

A recent study published in the Journal of Ethnic and Migration Studies found that public attitudes towards immigration are shaped by job demand rather than just skill level. The research showed that citizens in both England and Japan were more likely to grant visas to workers in high-demand occupations, regardless of their skill level.

Classic recessive-or-dominant gene dynamics may not be so simple

Researchers at Stanford University tracked the evolution of fruit fly populations in response to pesticide exposure, finding that resistance alleles persist through a mechanism known as 'dominance reversal.' This process allows alleles to function as either dominant or recessive depending on environmental conditions, maintaining geneti...

Mount Sinai study reveals genetic clues explaining why obesity affects people differently

A recent Mount Sinai study analyzed genetic data from over 452,000 individuals to identify genetic differences linked to higher body fat but better metabolic health. The researchers discovered eight distinct obesity subtypes, each associated with unique health risks, and developed a genetic risk score to predict individual outcomes.

Your ecosystem engineer was a dinosaur

A University of Michigan study reveals that the sudden loss of dinosaurs allowed forests to flourish, stabilizing sediments and creating broad meanders in rivers. This change had a profound impact on landscapes, demonstrating how life can alter its environment through catastrophic events.

The Lancet Diabetes & Endocrinology: Higher doses of semaglutide can safely enhance weight loss and improve health for adults living with obesity, two new clinical trials confirm

Two large-scale clinical trials found that a higher dose of semaglutide significantly improves weight loss and related health outcomes in adults with obesity. The study revealed an average weight loss of nearly 19% in those receiving the higher dose, compared to 10% with the standard dose or placebo.

Overweight and obesity don’t always increase the risk of an early death, Danish study finds

A Danish study found that individuals with a normal weight range (22.5-25 kg/m2) had the lowest mortality rate, followed by those in the overweight category. However, being underweight was associated with a significantly higher risk of death, while severe obesity was linked to a slightly increased risk. The study suggests that BMI may ...

Cannabis use associated with a quadrupling of risk of developing type 2 diabetes, finds study of over 4 million adults

A new study analyzing real-world data from over 4 million adults found that cannabis users face almost four times the risk of developing type 2 diabetes within five years compared to non-users. The study suggests that long-term metabolic effects of cannabis use may be linked to insulin resistance and unhealthy dietary behaviors.
