The faint object was revealed by just four globular star clusters hiding in the Perseus cluster. While most galaxies blaze with billions of stars, a rare few are so faint they are barely detectable. These low-surface-brightness galaxies contain very few stars [...] Show less

Read more Autonomous drones that can follow people or objects on their own are becoming more common in policing, border security, and surveillance. These aircraft use camera-based artificial intelligence systems to lock onto a target and track it without human control. While the technology offers many benefits, new research shows it also has a serious weakness that […] The post How an ordinary umbrella can trick and capture autonomous drones appeared first on Knowridge Science Report.

Read more High blood pressure is often called a silent killer because many people do not feel sick even when their numbers are dangerously high. Doctors usually explain it as a problem of the heart and blood vessels, but new research suggests the brain and nervous system may play a much bigger role than we once thought.

Read more Scientists have discovered a surprising link between a common nutrient in our food and how long men may live. The nutrient is called tyrosine, a natural substance found in many protein-rich foods such as meat, eggs, dairy products, and some plant sources. Tyrosine is also sold as a supplement because it helps the body produce […] The post Could too much of this common nutrient shorten men’s lives? appeared first on Knowridge Science Report. Show less

Read more For millions of years, seaweeds and tinyeConfig microscopic organisms have survived under harsh sunlight in shallow waters where ultraviolet rays are intense. Unlike humans, they cannot move into the shade, so they developed their own chemical protection. Scientists have long known that these tiny ocean organisms produce special natural compounds that act like sunscreen. Now, […] The post Seaweed compounds may help control high blood pressure, study finds appeared first on Knowridge Science Report. Show less
