The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane... Read more ›

Researchers investigated the relationship between historical traumatic events experienced by Alaska Native communities and epigenetic markers on genes that previous studies have linked to trauma. The new study found a similar pattern among Alaska Native participants, with specific epigenetic differences observed in those who reported experiencing the most intense symptoms of distress when reflecting on historic losses.

Some patients have experienced incredible recoveries after CAR-T-cell therapy. But they've also endured incredibly strong and scary side effects, in part because of the lymphodepleting chemotherapy that is performed before the CAR-T-cells are reinfused. What if CAR-T-cell therapy could be performed without lymphodepleting chemotherapy? Read more ›

Researchers have identified the structure of a special transporter found in red blood cells and how it interacts with drugs. Details on the findings could lead to the development of more targeted medicines. The research team found that this transporter facilitates the movement of a substance called bicarbonate, which certain drugs can inhibit. They discovered how these drugs block the transporter and devised novel compounds capable of achieving the same... Read more ›

Researchers have developed the first electronic device for continuously monitoring the health of transplanted organs in real time. Sitting directly on a transplanted kidney, the ultrathin, soft implant can detect temperature irregularities associated with inflammation and other body responses that arise with transplant rejection. Then, it alerts the patient or physician by wirelessly streaming data to a nearby smartphone or tablet. In a rat study, it detected rejection up to... Read more ›

An analysis of electronic health records for more than 60,000 adults in the United States found that systolic, or top-number, blood pressure rose slightly during the winter compared to summer months. The health records were of adults being treated for high blood pressure from 2018 to 2023 at six health care centers of varying sizes located in the southeast and midwestern United States.
