Researchers have uncovered a previously overlooked immune cell that can recognize and kill small cell lung cancer, the most aggressive form of the disease globally. Published in Cancer Cell, the WEHI study found patients with higher levels of these cells lived longer, uncovering a hidden immune defense that could be exploited to attack these hard-to-treat tumors.

Starting a walking routine takes very little: comfortable, supportive shoes and your own two feet.

A research team from the Faculty of Dentistry at The University of Hong Kong (HKU), working in collaboration with Su Ryon Shin’s group at Brigham and Women’s Hospital, Harvard Medical School, has advanced and preclinically validated a shape-adaptive hydrogel designed for challenging clinical trauma scenarios involving severe bleeding, irregular bone defects and comminuted fractures.

Opioid painkillers are some of the strongest analgesic medicines, but they are also the riskiest owing to a range of side effects, including addiction. An experimental opioid painkiller designed to be reversibly switched on and off with different light frequencies, keeping its action local and out of the brain, may eliminate the dangerous side effects of current opioids, according to a study led by Weill Cornell Medicine and University of Pennsylvania investigators. The findings herald a broad new approach for targeting medicines more precisely and effectively.

Heart failure (HF) is a condition in which the heart is not able to pump blood effectively. However, its effects go beyond pumping and circulation. HF is also known to cause a lasting form of innate immune memory in stem cells that synthesize blood and progenitor cells that are present in the bone marrow (BM). This can result in the production of immune cells that promote inflammation and worsen heart function. However, the exact mechanism of this process remained unclear.
