Genetics

A one-time gene therapy using a patient’s own stem cells has effectively cured a deadly immune disorder in 95% of treated children, offering a lasting, donor-free solution to ADA-SCID, known as the “bubble boy” disease.

A high-fat, low-carb ketogenic diet may protect the brain from early Alzheimer’s disease changes in people genetically at risk, new research suggests, by rebalancing gut bacteria and restoring brain energy metabolism.

Scientists have rejected claims that acetaminophen is a key driver of autism spectrum disorder, cautioning that research is inconclusive and excludes genetics and a suite of other influences. What's more, it focuses on a "cure," not understanding.

A study involving more than 1,000 cancer patients has found that a low dose of aspirin halves the risk of colorectal tumors returning after surgery. This readily available and affordable treatment could change the health outcomes of many survivors.

Got asthma? Then you might also go on to get Parkinson's. Celiac? You'll want to watch out for lung cancer. That's the kind of information you can get on a new website that uncovers the links between common conditions based on genetic analysis.

If you deal with waves of daytime drowsiness, you might be among the estimated 33% of the population suffering from excessive daytime sleepiness. In the largest study of its kind, scientists have uncovered the condition's unique biological fingerprint.

In a groundbreaking study, scientists have mapped the most detailed genetic blueprint yet of frailty – the age-related decline that affects around 40% of people aged 65 and over. It provides new hope for developing precision anti-aging therapies.

We know autism is not a single, homogeneous condition. Instead it's shaped by different traits, genes, and life experiences. Scientists have now discovered four distinct types of autism, each with its own biological signature.

For decades now, obesity has been defined by a number on a scale or where you land on the body mass index measure. But a groundbreaking study has found that it’s far more complex, finding 11 distinct biological types, each with their own health risks.

The evolutionary ladder is meant to be climbed one rung at a time with an organism shedding some traits and gaining others on the way up. However, in a very surprising twist, some tomatoes on the Galapagos islands are inching back down the ladder.

A new organelle has been found by scientists at the University of Virginia. The super-small specialized structure has a role recycling material inside our cells, and its discovery could lead to improved treatments for a wide range of diseases.

Exposure to common metals has again been linked to ADHD and specific symptoms. It builds on existing research that has found a strong association between environmental contaminants like lead and a higher rate of people diagnosed with the condition.
