Scientists studied how a common steroid, prednisolone, affects bone health in young rats. They looked at three blood markers that show how fast bones build and break down: a protein from new bone, another marker of bone strength, and one that signals bone loss. The team also checked the bones with d
Scientists in Spain studied how pregnancy hormones can change the brain’s gray matter. They used MRI scans and urine tests on 179 women, tracking changes before, during, and after pregnancy. The research showed that gray matter – the part of the brain involved in thinking and feeling – can shrink by
Climate change is worsening mental health problems worldwide. Researchers wanted to see if nature‑based activities could help people feel better when the planet warms. They gathered every study that looked at green spaces, gardening, or outdoor therapy and checked how many people benefited.
Copper nanoparticles that glow in the dark are being tweaked so they shine brighter and last longer inside tiny point‑of‑care test kits. Scientists are using two tricks: covering the particles with a protective polymer (polyacrylic acid) and letting them clump together when special metal ions are ad
The night sky lit up with a red moon on March 3, 2026. Astronomers and amateur sky‑watchers saw Earth’s shadow turn the full moon into a blood moon. The event began as a partial eclipse and moved into totality before ending later that night. People in New Zealand filmed the moon as Earth’s shadow m
Scientists have long wondered how life first appeared on our planet. One idea suggests that tiny organisms could travel between worlds inside space rocks, a concept called lithopanspermia. While no proof of alien life on Mars exists yet, researchers at Johns Hopkins University tested whether bacteri
Researchers have turned their attention to how people’s religious beliefs influence the way they act and relate to others. This study looks at the most cited papers in this area, aiming to map out what ideas dominate and how they connect. By using a method called bibliometrics, the authors counted r
A team of researchers tackled the tricky problem of tracking ammonia gas during the breakdown of sewage sludge. Ammonia levels swing wildly because many factors—time, airflow, acidity, and the amount of organic material—interact in complicated ways. Traditional statistics struggle to untangle these
Carbon quantum dots, or CQDs, are like tiny solar panels that can clean polluted water. They work because their surfaces can be tweaked, and they separate electric charges very well. Scientists have shown that these dots can break down nasty chemicals such as antibiotics, dyes, and phenols with high
A new laboratory method has been created to spot harmful chemicals called polycyclic aromatic hydrocarbons, or PAHs, in fatty fish. The technique mixes solid‑phase extraction with gas‑liquid microextraction, using ultrasound to shake the samples. First, a sonicator breaks open the fish cells a
