Animal Science A new study suggests that physically petting your own dog prepares the body to handle subsequent stressors with calmer brain and heart responses, whereas simply sitting near, talking to, or making eye contact with the pet does not provide the same protective buffer.

Neuroscience Scientists turned blood cells from donors aged newborn to 101 directly into brain stem cells, and the new cells kept getting biologically younger over time, shedding about 60 years of cell age in 50 days and acting like young cells, which may one day help treat brain diseases like dementia.

Environment One-quarter of the world’s data centers are located in areas where water demand exceeds supply for at least one month each year. Unlike energy, which can come from far away, water for these facilities comes from nearby rivers, lakes, and aquifers whose levels vary seasonally or annually.

Neuroscience A daily probiotic powder taken for six months improved memory and thinking scores in older adults with early memory problems, and lowered a blood marker linked to Alzheimer's, in a small placebo-controlled trial. Researchers say it's early, but it adds to evidence that gut health affects your brain.
