Push to return to "traditional" masculinity imposes costs on men, BGU social psychologist maintains

A Ben-Gurion University social psychologist argues that toxic masculinity and traditional gender roles impose significant costs on men, affecting their personal and professional lives. Men are pressured to conform to narrow standards of masculinity, leading to increased stress and negative mental and physical health outcomes.

A metabolism switch that could help stop the spread of pancreatic cancer

Scientists have discovered a potential new treatment strategy for pancreatic cancer by identifying the molecule Neuropeptide Y (NPY) as a key driver of its spread. Blocking NPY's function has been shown to reduce cancer cell movement and metastatic outgrowth, potentially limiting disease progression.

New NUS study: Poor sleep health linked to increased Type 2 diabetes risk in high-risk women with history of gestational diabetes

A new study found that poor sleep health is associated with a higher risk of developing Type 2 diabetes among women with a history of gestational diabetes. Women who slept six hours or fewer per night had a 32% higher risk compared to those who met the recommended seven to eight hours of sleep.

Conclusion of global, multicentre trial defines aspirin’s role in reducing colorectal cancer recurrence

The ASCOLT trial found that aspirin does not statistically improve disease-free survival for all patients but demonstrates a consistent trend of improving overall and disease-free survival. Aspirin taken for up to 3 years is efficacious in patients with PIK3CA mutation, reducing recurrence by over 50%.

Sulfur amino acid restriction enhances fat loss and metabolic health

A recent study found that a sulfur amino acid restriction diet induces rapid fat loss and enhances glucose sensitivity in mice without impacting appetite or physical activity. The study identified cystine as a key regulator of fat metabolism, suggesting its potential implications for weight management in diabetic patients.

Left-right symmetry-breaking of a cellular flow occurs earlier than node formation

Researchers from Kumamoto University and colleagues found that left-right symmetry-breaking occurs prior to node formation, indicating a tightly regulated program for asymmetry. This study demonstrates the involvement of physical mechanisms in biological patterning using quantitative biophysical parameters.

Burden of cardiovascular disease caused by extreme heat in Australia to more than double by 2050

Research published in the European Heart Journal suggests that Australia's burden of cardiovascular disease caused by extreme heat will more than double by 2050. The study found that hot weather costs around 49,483 years of healthy life annually, with this number expected to increase significantly under climate change scenarios.

Who does Darth Vader vote for? Not the same party as Harry Potter

A study published in Political Science Research & Method found that around one in six people falsely recall the party affiliation of a politician, with those who admire a hero more likely to see it as their own party. Researchers say this projection could be fuelling polarisation in politics.
