Aging is a complex process. It's not just about time passing. It's about what happens inside our cells. Telomeres, the protective caps on our chromosomes, get shorter every time our cells divide. Eventually, this leads to cellular senescence, a state where cells stop functioning properly. This is a
A 65-year-old woman had a serious shoulder issue. Her shoulder kept popping out of place. Doctors called this "chronic anterior shoulder instability. " It was caused by weak shoulder ligaments. This made her shoulder unstable and painful. First, doctors tried to fix her shoulder with a simple proce
The U. S. dollar has taken a significant hit this year, dropping more than 10% in value. This is the worst decline since 1973, when President Nixon ended the gold standard.

A new space traveler has caught the attention of astronomers. This visitor, named 3I/ATLAS, is the third interstellar object ever spotted in our solar system. It was first seen on July 1, 2025, by a telescope in Chile. The object's unusual path quickly revealed it wasn't bound by our sun's gravity,
A huge comet, Bernardinelli-Bernstein, is making waves in the solar system. It's not just its size that's impressive—it's also acting in ways that surprise scientists. This comet, one of the largest ever found, is releasing jets of carbon monoxide gas, and it's doing this while still very far from t
North Carolina faced severe flooding after Tropical Depression Chantal dumped a lot of rain in central parts of the state. The rain caused serious damage, leading to states of emergency in Moore and Orange counties. Many roads and highways were closed due to the flooding. A section of Interstate 40
Researchers dug into how certain markers in the blood might hint at heart trouble. They focused on two things: ferritin and glutathione peroxidase 4 (Gpx4), which are tied to a process called ferroptosis. This process is linked to cell damage and death. The study looked at 396 people with coronary
Scientists have been curious about how the shape of molecules influences their behavior. Specifically, they want to understand how changes in the length-to-width ratio of molecules can lead to the formation of different phases, known as mesophases. This is important because these phases have unique
In the world of healthcare, AI chatbots are making waves. Four of them—DeepSeek-V3, DeepSeek-R1, OpenAI o3-mini, and OpenAI o3-mini high—were put to the test on urology questions. The goal? To see how well they handle topics like benign prostatic enlargement, urinary stones, infections, and the late
In the world of skin care, some chemicals do more than just sit on the surface. They dive deep into cells and mess with important signals. Three of these chemicals are lawsone, juglone, and plumbagin. They are found in many skin treatments and cosmetics. But how do they really work? Scientists want
