Prostate-specific antigen (PSA) is a protein made by the prostate gland. A PSA test is a blood test that checks the level of PSA in a man’s blood. High levels can indicate a number of prostate issues, including inflammation, an enlarged prostate (benign prostatic hyperplasia, or BPH), or prostate cancer.[1]An estimated 37 percent of men ages 50 and older have had a PSA test in the past year. This screening test offers a way to detect prostate cancer early — up to seven years before symptoms appear.[2]But certain things, such as medications or an infection, could cause the number on…

It’s the coziest time of year! We’re jazzed about fall, and we’re excitedly anticipating the holiday season. I like to decorate early—I want to get the most out of my festive purchases. My Halloween doormat has been out since August with no shame.

The intervention also raised blood serotonin, the neurotransmitter 5-HTP helps produce. However, anxiety scores and Alzheimer’s-linked blood proteins did not change.The study enrolled 30 adults with a mean age of 66 to 67. Participants were randomized to 100mg 5-HTP nightly or no 5-HTP. After 12 weeks, the 5-HTP group improved their Montreal Cognitive Assessment (MoCA) total score by about one point (from 26.6 to 27.6 out of 30), a statistically significant within-group change.The control group showed no meaningful shift. Serum serotonin rose in the 5-HTP group and fell slightly in controls. Depressive symptoms, measured by the Geriatric Depression Scale (GDS),…

On arriving at work one day last October, ecologist Koen de Koning did what he often does first thing in the morning: he fired up the Crane Radar. The interactive web application showed a flock of cranes heading his way. Excitedly, he dashed outside, looked up and, sure enough, 60 or so birds flew past on their migration route south.The Crane Radar is a digital twin — a virtual representation of a real-world entity and a relatively new technology in ecology (see go.nature.com/46rbkg4). “I’ve definitely seen more of the migration because of the radar. And I’m learning more about the…

Multivitamins can interfere with the absorption and metabolism of certain medications.Blood thinners, thyroid medications and diuretics are just some of the drugs that don’t mix well with multivitamins.Take to your pharmacist or health care provider about any medications you’re taking that may interact with a multivitamin. About one-third of U.S. adults take a daily multivitamin, often to fill nutritional gaps or as a form of “insurance.” While most multivitamins are safe for healthy adults, combining them with certain medications can change how your body absorbs either the supplement or the drug itself. That’s because vitamins and minerals share the same…
