Within the race to develop sturdy notion methods for robots, one persistent problem has been working in dangerous climate and harsh circumstances. For instance, conventional, light-based imaginative and prescient sensors reminiscent of cameras or LiDAR (Gentle Detection And Ranging) fail in heavy smoke and fog. Nevertheless, nature has proven that imaginative and prescient would not … Read more
Changes in the gut microbiome before rheumatoid arthritis is developed could provide a window of opportunity for preventative treatments, new research suggests. Bacteria associated with inflammation is found in the gut in higher amounts roughly ten months before patients develop clinical rheumatoid arthritis, a longitudinal study by Leeds researchers has found. Affecting more than half … Read more
Colors are widely used in communication within and among animal species. For example, peacocks proudly display their vibrant tails, adorned with iridescent eyespots, to attract peahens for courtship. This is a classic example of sexual selection using color signaling. Conspicuous colors are also displayed by toxic animal species, including many venomous snakes and the brilliantly … Read more

Dangling from a weather balloon 80,000 feet above New Mexico, a pair of antennas sticks out from a Styrofoam cooler. From that height, the blackness of space presses against Earth’s blue skies. But the antennas are not captivated by the breathtaking view. Instead, they listen for signals that could make air travel safer. Researchers from … Read more
Extreme-mass-ratio binary inspiralling in an environment of dark matter. The movement of small black holes creates a dense wake trail that slows it down, affecting the gravitational wave signal. Credit: Beatriz Oliveira and Rodrigo Vicente. A recent study in Physical Review Letters explores the effects of ultralight dark matter in extreme-mass-ratio inspirals (EMRIs), which could … Read more
