Creating new drugs is tough and expensive. Right now, scientists use flat cells or animals to test drugs, but these methods don't always work well for humans. That's where new tech comes in: tiny, 3D versions of human organs, called organoids, and special chips that mimic how organs work. These tool
When winter arrives, ice becomes a common problem. To tackle this, people often use ice melts. Two popular choices are calcium chloride and sodium chloride. Both work by lowering water's freezing point, but they do so in different ways. Sodium chloride, or rock salt, is widely used. It disrupts the
Deep inside a cave in southern Italy, a remarkable discovery has been made. The Altamura Man, a Neanderthal fossil trapped in rock, has given scientists their first-ever look at a Neanderthal's nasal cavity. This is a big deal because these delicate bones usually don't survive in fossils. Researche
Aluminum has always been a popular choice for making things light and strong. But what if it could be even stronger? That's where single-walled carbon nanotubes (SWCNTs) come in. These tiny tubes are incredibly strong and have a large surface area, making them perfect for reinforcing materials. The
A comet named 3I/ATLAS has been making headlines since its discovery on July 1, 2025. This comet is special because it's only the third interstellar visitor we've seen in our solar system. But what's really got scientists buzzing is its strange behavior near the sun. It's speeding up in a way that g
Silicon and diamond detectors are now commonly used to measure the energy deposited by ion beams in water during radiation therapy. This energy is described by a value called dose-averaged linear energy transfer (LET). The problem is that these detectors don't always give accurate readings. The reas
A recent study has stirred up quite the debate. It suggests that a small rise in global sea levels could lead to harsher winters in East Asia. The idea is that a 15-30 cm increase in sea levels might tweak atmospheric patterns, making cold snaps more intense. But is this claim backed by solid eviden
The UK's Met Office Space Weather Operations Centre, established in 2014, has been working to help the country prepare for space weather events. They provide daily forecasts, including four-day geomagnetic storm forecasts (GMSF) and X-ray flare forecasts (XRFF). But how good are these predictions?
Hurricanes are more than just powerful storms; they can drive evolution in surprising ways. Take the brown anole lizard, for example. These critters have been spreading across the southeastern United States for over a century. During this time, they've faced a lot of hurricanes. Scientists wanted to
In Virginia, scientists have been studying deer bones to figure out where these animals come from. The goal is to find better ways to track movements of both animals and humans. Right now, it's tough to pinpoint exact locations using animal tissues. Three things were looked at in the bones: oxygen,
