New research is helping to clarify scientists’ understanding of how post-heart-attack cardiac function sometimes improves after injections of cells. Hearts are healing, not actually regenerating tissue as many thought, the new research suggests.

The taller you are the more likely you are to develop atrial fibrillation, according to a new study relying on genetic data from more than a million people. Every inch in height over 5 feet 7 inches translates into about a 3 percent increase in AFib risk, according to the Penn Medicine study.

Stem cell transplants continue to yield positive results in patients with multiple sclerosis and other autoimmune diseases, with the latest milestone emerging from Northwestern Medicine and Mayo Clinic.

Unfortunately, an established test for ovarian cancer, the CA125 test, is limited in its power and not recommended for general screening. Researchers in Ireland have come up with a potential improvement, a blood test that may be able to detect ovarian cancer one to two years earlier than current approaches.

One dose of one treatment to defeat multiple types of cancers? That’s the intriguing, if far-off, possibility suggested by a new development by UCLA scientists working with mice. The scientists focused on boosting production of “killer” immune cells that, though powerful, aren’t naturally prevalent enough in humans to make much of a difference for cancer patients.

October officially kicks off Breast Cancer Awareness Month. Breast cancer is the most common cancer in women with about 245,000 new cases and 41,000 deaths each year.

Scientists have studied the human brain for millennia, but only recently have they been cultivating brains – well, “minibrains” – from scratch: Researchers at University of California San Diego have programmed human stem cells to grow the pea-sized organoids of brain tissue in the lab.

Alzheimer’s disease remains stubbornly resistant to cures, though some progress is being made, especially on the diagnostic side. “We don’t have a lot of positive news these days,” Martin Tolar, CEO of Alzheon, told STAT for a story on last month’s Alzheimer’s Association International Conference in Los Angeles. “But I do believe there’s a lot […]

A human biospecimen is a potential font of biological data—data that when aggregated in enormous volumes and crunched by artificial intelligence drives the development of precision medicine. By analyzing genetic profiles of patients and tumors, and by matching mutations to targeted drugs, precision medicine is halting or reversing cancer…in a small fraction of cases.
