The origins of Papua New Guineans have long puzzled researchers due to their unique physical features, which resemble Sub-Saharan Africans despite genetic ties to Asians. A groundbreaking study, published in Nature Communications and led by Dr. Mayukh Mondal, used artificial intelligence to unravel their complex genetic history. The AI-driven research revealed vital insights into their ancestry, linking them to ancient …

LAUSANNE, Switzerland — Olympic champion Imane Khelif has appealed against a World Boxing decision barring her from upcoming events unless she undergoes genetic sex testing. The Court of Arbitration for Sport said on Monday that the Algerian boxer filed the appeal last month.

When an Amish patient arrived at the Children’s Hospital of Philadelphia with fatigue, a severe headache, and weakness on one side of her body, doctors scrambled to find a cause. All they could see was that she had brain inflammation. That’s usually caused by an infection, but her tests came back normal. High dose steroids, a standard treatment, weren’t effective. …

The mountain of evidence backing the health perks of the Mediterranean diet—one that highlights plant foods and fish, and de-emphasizes red and processed meats—just grew again. A study using data from more than 5,700 people gathered over 34 years found that the participants who stuck to the Mediterranean diet were less likely to wind up with dementia. But the biggest …

A new test helps predict which kids face the largest genetic risk of a high body mass index (BMI) later in life. That could help parents establish healthy habits early on. The new test, put together by a large team of international researchers, is what’s known as a polygenic score or PGS. These scores are used to group genetic variations …

Summary: Researchers have identified a genetic region, HAR123, that may help explain what makes the human brain unique. Acting as a transcriptional enhancer, HAR123 influences the development of neural progenitor cells, which give rise to neurons and glial cells, and plays a role in determining their ratio. This regulation appears to support cognitive flexibility, a distinctly human trait involving the …
