A new form of age “clock” can evaluate chronic inflammation and forecast if someone is in danger of age-related diseases including cardiovascular and neurological disease. The clock gauges a person’s biological age, which takes into account their health and might be greater or lower than their chronological age. The inflammatory aging clock (iAge), published in…

Radar has been around for nearly a century. Radar is a simple and elegant element of humanity’s technological toolbox: you put out radio waves, a receiver picks up their reflections, and you examine the waves to figure out where and how far away things are. Designers can now develop complex radar systems that employ many…
Sea otters have a difficult time keeping warm. The animals spend the majority of their time in the water, which absorbs heat 23 times faster than air. Their habitat in the North Pacific is extremely cold, with water temperatures ranging from 0 to 15 degrees Celsius (32 to 59 degrees Fahrenheit). Sea otters are also…
