In the world of mental health, doctors often rely on people telling them how much they drink. This can be tricky because memories and honesty are not always perfect. A new approach uses tiny gadgets that sit on the skin to detect alcohol molecules as they leave the body. The devices read chemical si
These tiny 3‑D cultures, called organoids, are changing how scientists study lung cancer. Instead of flat cell sheets or animal models that take months to grow, organoids can be produced quickly while keeping the original tumor’s structure and variety. Researchers now grow lung cancer organoid
Scientists have found that winter seasons are getting noticeably shorter in many U. S. cities, especially those near the Great Lakes. The new analysis looked at 245 weather stations across the country and compared data from two time periods: 1970‑1997 and 1998‑2025. In most places, the coldest part
In today’s digital world, dating apps can feel like a fast‑paced sales pitch where people compare themselves to items on sale. A researcher who has spent decades studying relationships says this focus on “mate value” is a myth that makes dating feel more like a job than a journey. He argues that rea
People around the world struggle with lung diseases that cause many deaths. Scientists are trying to understand if how much we move or sit affects the risk of getting these illnesses. A new study used a genetic method called Mendelian randomization to investigate the link between physical acti
In the fight against climate change, architects are looking for ways to make buildings more eco-friendly. One big challenge is figuring out how wind affects buildings early in the design process. Most tools for this job are used late in the game, but small changes early on can make a huge difference
Scientists discovered that tiny fragments from mouse mitochondria can make the body’s defense cells work against tumors. These fragments, called formyl peptides, are normally produced when bacteria or mitochondria break down proteins. Researchers first identified five specific mouse peptides t
The blog “Watts Up With That” claims to be a top source for climate science. It gathers research, news and expert views about how Earth is changing and what that means for people. Its focus areas include the causes of global warming, predictions about future temperatures and how scientists study th
A new soft robot moves through water by using light instead of batteries. The device is made from a single sheet of liquid‑crystal gel that has been patterned so its internal molecules twist in a way that produces a traveling wave when it is illuminated. When a laser scans across the sheet, the gel
NASA’s plan to send a crew to the moon after half a century has hit a snag. During a practice launch on January 31, 2026, the rocket that will carry four astronauts began leaking liquid hydrogen. The leak forced engineers to stop the fuel flow, fix it, and then restart—only for the problem to recur
