There is a growing need for high-speed trains to offer broadband services. This is because more people are traveling between home and work. The current radio frequency technology is not up to the task. It cannot handle the demand for high-speed data transfer. A possible solution is free space optics
Medical teams often rush into chaotic situations. They focus on saving lives. But there's another crucial aspect they must consider. Crime scenes can hold vital clues. These clues can help solve crimes. Yet, medical teams might unintentionally mess with these clues. This is where training comes in.
The Kentucky Derby is back, and so is a familiar face. After a three-year break, trainer Bob Baffert returns to Churchill Downs. He's known for winning the Derby six times, but this year, one of his horses was pulled from the race. Still, his remaining horse has a fighting chance. The Derby is unlik
Drought is a serious issue. It can mess with plant and soil communities in big ways. Scientists often use rainout shelters to study how drought affects these communities. These shelters block a set amount of rain, while nearby control plots get the usual rainfall. This setup has helped researchers l
The world is warming up. This is a fact. And it's affecting our food. Rice is a staple for many. But it's sensitive to heat. Too much heat can ruin the crop. This means less rice and poorer quality. But there's hope. Scientists have found a single gene. This gene helps rice handle the heat. It's a b

Cycling sprints can boost both aerobic and anaerobic fitness. These intense, brief efforts usually last ten seconds or less. However, the immediate effects of varying cycling power on the body and mind during these short bursts are not fully understood. This is where the study comes in. It focuses o
The liver of triploid rainbow trout faces unique challenges in low-oxygen waters. To understand how these fish cope, researchers dug into the world of tiny gene regulators called miRNAs. They found 45 miRNAs that change their activity when oxygen levels drop. These miRNAs don't work alone. They team
