Imagine you're trying to count all the ways you can make a puzzle work. In the world of computer science, this is like #k-SAT, where you're looking for solutions to a problem. Researchers have just found a clever trick using randomness to count these solutions super fast, in a time that grows slower
NASA astronaut Don Pettit recently snapped a photo from the International Space Station (ISS) that shows something quite fascinating. The Betsiboka River estuary in Madagascar, when seen from 250 miles above Earth, looks a lot like the tiny blood vessels in the back of our eyes, known as the retina.
Imagine you're on an automated shuttle, zipping through the University of North Carolina in Charlotte. From July to December 2023, researchers were watching how well these shuttles handled their routes. They collected lots of data, like GPS information, disengagement records (when the shuttle hands
Imagine you're living with a heart condition like stable angina. Now, picture how exercise could help. Researchers at Hebei Sport University created a unique exercise program for those dealing with coronary heart disease. They wanted to see if it could make a difference. The study included patients
Surface water is crucial for understanding and predicting disease spread, especially in monsoon-affected regions like India’s Western Ghats. Before the arrival of Sentinel-1 Synthetic Aperture Radar (SAR) missions, optical remote sensing was used to map water availability. However, cloud cover often
Recently, Mayor Brandon Johnson's campaign finance report revealed over $200, 000 in previously unreported funds. This comes after his spokesperson, Christian Perry, told Politico in early January that the mayor actually raised around $200, 000, despite an earlier report showing only $970 for the la
Winter isn't just about snow and cozy fires. It also brings some health risks you should know about. Dr. Steve Dorsey from the Cleveland Clinic says icy sidewalks are a big problem, leading to many falls. Shoveling snow can be tough on your heart, too. Cold weather can weaken your immune system, mak
Female Genital Mutilation (FGM) is a worldwide health issue. It's a non-medical practice that involves removing parts of the female genitalia. To understand the factors influencing when girls undergo FGM, researchers in Ethiopia analyzed data from the 2016 Ethiopian Demographic and Health Survey (ED
Fish populations in England's rivers have been on a rollercoaster ride over the past four decades. Once struggling due to water pollution and changes in land use, these aquatic creatures have shown remarkable improvements. Scientists looked at data from 16, 124 surveys at 1180 sites across England,
You know how plastic is everywhere and causing big problems? One idea to solve this is a cap-and-trade system, or CAT for short. This system has been used before to manage water and reduce carbon emissions. It works by setting a limit, or cap, on the amount of something, like plastic, that can be pr
