Researchers tracked fatal police shootings from 2015 to 2022 across more than 3, 000 U. S. counties. They found that out of every 10, 000 people, Black residents were 15 times more likely to be shot and killed by police than White residents. Hispanic residents faced about 2. 5 times higher risk than
Researchers turned to a classic game to teach AI how to make smarter choices in scientific work. The game was Battleship, where players guess ship positions on a hidden grid. Instead of just playing for fun, AI used the game to practice managing limited resources—just like scientists do when running
Researchers have taken a new look at a 17th‑century book about magnetism that first appeared in 1600. They didn’t just count how many copies survived; they also read the notes people wrote inside those books. By combining these two kinds of data, the team could see where readers stopped, highlighted
Researchers are studying a rare form of Alzheimer’s that runs in families, where symptoms almost always start at the exact same age. This special case helps scientists spot brain changes years before people feel sick. While doctors can now detect tiny clues in blood tests, experts still don’t fully
Researchers tracked how often a drug called bevacizumab improved survival without causing new lung damage in people fighting the most common type of lung cancer that starts outside the lungs. The study looked at adults who had never been treated for this cancer but were about to start a standard fir
Researchers followed adults from 2011 to 2020 to see if how long someone has arthritis matters for breaking a hip. Hip fractures hurt life and can be fatal, especially in older people. Arthritis is common and may weaken bones or make walking harder. The study looked at middle‑aged and older Chinese
Researchers often turn to large health databases to study surgical outcomes. One popular option is TriNetX, a platform that collects real-world medical data. But can it really help answer key questions about surgeries? The short answer is yes—but only if used carefully. TriNetX pulls patient record
Researchers looked at whether tough childhoods could show up in gum disease later in life. They focused on young adults in China who had faced hardships like neglect, abuse, or unstable homes—what experts call adverse childhood experiences. The study also checked for signs of depression and general
Research has shown that certain psychedelic drugs can lower people’s tendency to support strict, top‑down authority. However, these studies were small and not always well controlled. Because of that uncertainty, scientists are calling for bigger experiments with stricter designs to see if the eff
Researchers have spent years chasing a cure for Alzheimer’s, focusing on how proteins called amyloid clump together in the brain. Back in the 1990s, scientists, including one leading expert, realized that these clumps might harm brain cells and trigger inflammation. At first, they thought fixing thi
