Prostate cancer has once again captured global attention following the recent diagnosis of former US President Joe Biden, shining a spotlight on a disease that is the most common cancer among men worldwide. While headlines often tout new prevention measures or promising lifestyle tweaks, leading experts have clarified that the factors most responsible for a man’s risk of developing prostate cancer lie largely beyond individual control: age, ethnicity, and family history. This evidence-based perspective, backed by the latest research, has vital implications for men in Thailand, where rising cancer rates are signaling the need for smarter screening and public health strategies.

The assumption that mental disorders are largely inherited from our parents—a bedrock belief of biological psychiatry for decades—is now under serious scrutiny. According to a detailed new analysis published in May 2025, current research demonstrates that heritability explains far less about mental illness than previously assumed, prompting renewed calls for a broader understanding of the interplay between genes, environment, and psychology in shaping mental health (Madin America).

Why does this matter for Thai readers? In a country where mental health awareness is only now gaining national attention, public discourse often echoes global trends in medicine and psychiatry, including an emphasis on genetic causation. Many Thais, especially in urban areas, may be told that conditions like depression, anxiety, or schizophrenia run in families and are predominantly genetic. Understanding that mental disorders stem from more than just DNA could help counter stigma, inform policy, and inspire more comprehensive mental health support across the country.

A new discovery is sending ripples through the medical world: scientists have identified a gene called PHGDH not just as a bystander but as a direct cause of Alzheimer’s disease, potentially changing the diagnosis and treatment of this devastating condition. Uncovering a previously unknown function of this gene, researchers have also pinpointed a candidate drug-like compound that may one day prevent or slow the disease in its earliest stages – a major leap forward, especially for aging societies like Thailand.

A century-old mystery surrounding the striking orange coats of domestic cats has finally been unraveled by new genetic research published on May 15 in the journal Current Biology (source). Scientists have identified a unique “meow-tation” in feline DNA that not only gives orange cats their distinctive hues, but also explains why the vast majority of them are male—a question that has perplexed geneticists and cat fanciers alike since the early 20th century.

A recent international study has revealed that higher concentrations of caffeine in the blood may help reduce body fat and lower the risk of developing type 2 diabetes, sparking fresh debate about caffeine’s broader health effects for Thais and coffee lovers worldwide.
