Trees vs. disease: Tree cover reduces mosquito-borne health risk
A study finds small-scale tree cover in Costa Rica boosts biodiversity while limiting dangerous mosquito species.
When climate disasters hit, they often leave long-term health care access shortages
Immediate recovery efforts receive the most attention after severe natural disasters, yet new data from researchers at Drexel University and the University of Maryland suggests these climate events often also…
Resetting the fight-or-flight response
The activation of Protein Kinase A (PKA) is a critical part in how the body responds to stress and starvation. Using a variety of imaging and biochemical techniques, a team…
Traditional diagnostic decision support systems outperform generative AI for diagnosing disease
Researchers compared their long-standing diagnostic decision support systems AI tool, DXplain, with modern large language models like ChatGPT and Gemini, finding DXplain performed slightly better. They say their findings suggest…
All-in-one model reconstructs complex liver architecture
The liver has a unique structure, especially at the level of individual cells. Hepatocytes, the main liver cells, release bile into tiny channels called bile canaliculi, which drain into the…
Gene editing disrupts Huntington’s mutation in mice
Researchers have developed a way to edit the genetic sequences at the root of Huntington's disease and Friedreich's ataxia. If longer than a certain threshold length, these sequences grow in…
Gut bacteria may hold key to unlocking better cancer treatment
'Biomarkers' may help to improve detection and treatment of gastrointestinal diseases such as gastric cancer, colorectal cancer, and inflammatory bowel disease.
Yeast can now produce human DNase1
The protein DNase1 is one of the oldest biological agents in history: It has been on the market since 1958 and is now used, among other things, to treat cystic…
Sustained in the brain: How lasting emotions arise from brief stimuli, in humans and mice
Humans and mice share persistent brain-activity patterns in response to adverse sensory experience, scientists find, opening a window to our emotions and, perhaps, neuropsychiatric disorders.
Dinosaurs could hold key to cancer discoveries
New techniques used to analyze soft tissue in dinosaur fossils may hold the key to new cancer discoveries. Researchers have analyzed dinosaur fossils using advanced paleoproteomic techniques, a method that…
