Results from an early-stage clinical trial, published in Nature Communications, showed encouraging outcomes among patients with newly diagnosed cancer whose tumors had spread to distant organs. Most strikingly, one patient experienced a pathologic complete response—meaning no viable cancer cells could be found—and remains cancerfree for more than two years without further treatment. These findings offer an important signal that a new approach may be able to overcome one of the disease’s greatest challenges: its resistance to immunotherapy.

“We desperately need new tools in our arsenal,” said Gulam Manji, MD, PhD, a medical oncologist specializing in pancreatic cancer and lead investigator of the trial...

Persistent pain often has no clear cause. However, studies show measurable differences in the structure and activity of the brains of those affected. This might explain why they experience chronic pain...

A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting responses against colorectal, skin, and breast cancer cells.

In experiments with obese laboratory mice, the researchers found that adding the supplement to the animals’ diets changed the way immune cells developed and produced stronger cancer-fighting responses.

Obesity can interfere with immune function, making it more difficult for the body to re...

NASA scientists found that microbes brought by astronauts could survive in cold, shadowed niches around the Moon’s South Pole, potentially complicating future searches for pristine lunar chemistry. Some refuges may be no larger than a footprint, while one hardy fungus could even withstand limited exposure to sunlight.

NASA scientists say some microbes carried into space by human explorers may be able to survive in sheltered, shadowed areas near the Moon’s South Pole.

The findings, published on Aug...
