Climate Change’s Earliest Detectable Sign Emerged 130 Years Ago

Climatology, Earth Science, Environmental Science /

Had 19th-century scientists possessed today’s advanced atmospheric tools, they might have detected the earliest signs of climate change caused by human activity—specifically, the burning of coal and wood. Scientists Suggest Climate Change Could Have Been Detected as Early as 1885 In a recent thought experiment, a group of Earth and atmospheric scientists concluded that, with

Only Certain Uranium Can Fuel Weapons. Here’s What Enrichment Involves

Physics /

When people hear “uranium,” they often picture mushroom clouds, Cold War tensions, or glowing green rods straight out of science fiction. But uranium is more than just a symbol of nuclear threat—it’s a relatively common element with vital uses in energy production, medical treatments, and global politics. The element returned to international focus in June

Monthly Injection Reduces Body Weight by 16% in Landmark Obesity Study

Healthcare, Medicine /

A new drug developed by California-based pharmaceutical company Amgen has shown strong potential as an effective obesity treatment. In a completed phase II trial, participants receiving a once-monthly injection of the drug—called MariTide—lost up to 16% of their body weight within a year. That level of weight loss is similar to the average results seen

Scientists Reveal Open-source Exoskeleton to Aid walking

Applied Science, Robotics /

Picture a future where robotic legs enable people with disabilities to walk independently. A new open-source exoskeleton project from Northern Arizona University is bringing that vision closer to reality. Currently, the high cost and time required to develop complex electromechanical systems often prevent research from getting off the ground. However, that could soon change.After years
