A new study examined the gene activity in nearly a thousand brain samples from people who had died with Parkinson’s disease, dementia with Lewy bodies, multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration, Alzheimer’s disease or no brain disease. The researchers used a
Scientists recently dug deeper into the genetic roots of two ethnic groups in Sichuan, China. They studied 100 people from the Qiang and Yi communities. Their goal? To map out how these groups connect genetically to others nearby. The findings show big similarities between the Qiang, Yi, and other
Mediterranean oak forests face a tough challenge: acorns rarely survive long enough to become new trees. A study in a protected area in Italy showed that most acorns disappeared within days after being planted, eaten by animals like mice and jays. The researchers tested four oak species, from large
Hereditary angioedema, or HAE, is a genetic condition that causes sudden, painful swelling under the skin or in the lining of the body's organs. These unpredictable flare-ups can block airways or cause severe stomach pain, making everyday activities dangerous. Scientists used to struggle to keep the
When blood vessels get clogged, three big health problems can happen: heart attacks, leg artery blockages, and strokes. These conditions all come from the same root cause—atherosclerosis, where fatty buildup hardens arteries. But do they share the same genetic risks? New research digs into this ques
When the day‑lily Hemerocallis fulva “Shaman” opens, it releases a bouquet that shifts over time. Scientists followed this scent journey by sampling petals at three key moments: the first blush, the peak bloom, and the last sigh. Using modern tools that spot tiny chemicals (volatile organic compo
Gum disease attacks the gums and the bone that holds teeth in place. The body’s defense cells called macrophages shift to a bad state that keeps damage going. Scientists looked for a simple tool that could flip these cells back to a repair state. They picked polydopamine, a natural coating that many
Less than a hundred years ago, music was something nearly everyone made. Children learned songs from parents, neighbors sang together at harvests, and towns had their own local sounds. Today, most of us are listeners, not makers. Generative AI is about to push that shift even faster, turning music f
A woman named Karyn Paringatai noticed a disturbing trend in her relatives: many died at a young age. When she traced their medical records, she found that a rare stomach cancer, known as diffuse gastric cancer, was common among Māori families like hers. This type of cancer can develop without
A group of Arkansas high school musicians is stepping into the spotlight this week, blending youthful energy with professional polish. The 20-piece big band, drawn from seven local high schools, marks its 10th year under the guidance of jazz educators and guest soloist Adam Larson, a saxophonist who
