Sexual assault investigations often face a tricky situation. There are usually more female cells than male cells in the evidence. This makes it hard to get clear DNA results. Scientists have been testing different ways to separate these cells. They want to find the best method to identify the attack
Young athletes, especially boys, go through big changes as they grow. A recent study looked at how training affects their jumping skills. Forty boys, aged 9 to 17, were split into two groups based on their growth stage. Some were still growing fast, and others had already gone through their main gro
In 1925, a small town in Tennessee became the center of a big debate. A teacher, John Scopes, was put on trial for teaching evolution. This was a big deal because Tennessee had a law against it. The trial was like a showdown between science and religion. Two famous figures, Clarence Darrow and Willi
Breath tests for cannabis are not new, but they usually focus on smoking. Now, researchers wanted to see if these tests could also detect THC from edibles. They had people eat cannabis-infused treats and then tested their breath at different times. Before eating the edibles, some participants alrea
Crime scene investigations just got a high-tech makeover. Scientists have found a clever way to detect blood using a smartphone and a special glowing chemical called luminol. When luminol meets blood, it lights up, and a smartphone can record the whole process in a video. This new method is not jus
In Ghana, students in health sciences face a big problem: sexual and gender-based violence (SGBV). This is not just a personal issue; it's a matter of human rights and social fairness. Sadly, not enough is being done to stop it. Most efforts to prevent SGBV are not tailored to fit the local culture
Seven former heads of NASA's science programs have joined forces to protest a huge budget cut. They want Congress to say no to a 47% reduction in NASA's 2026 science budget. This cut could stop many space missions and hurt thousands of scientists and engineers. It could also make the U. S. fall behi
Suaeda salsa, a plant that thrives in salty soils, has a special talent. It can soak up and store lots of nitrate, a type of salt. This makes it great for cleaning up polluted, salty lands. But how does it do this? Scientists wanted to find out. They looked at a specific gene in the plant, called S
The Hanjiang River in China is facing a hidden problem: tiny plastic particles. These small bits, called microplastics, are less than 500 micrometers in size. They are everywhere in the river and can harm aquatic life. A recent study used advanced technology to find out more about these microplastic
A big problem in chemistry is separating ethane (C2H6) from ethylene (C2H4). These gases are similar, but important for different industries. Scientists have been working on ways to do this better. One approach is using special materials called metal-organic frameworks (MOFs). These are like tiny s
