A new study by McGill University researchers finds that combined dry and hot events are increasing in frequency and size, causing widespread damage. The study suggests that climate change is driving these extremes, which can be particularly devastating for agriculture and ecosystems.
Adolescents with compulsivity traits show reduced brain development and delayed goal-directed behavior, suggesting a link between compulsivity and atypical cognitive development. Compulsivity is associated with less-pronounced remodeling of brain circuitry during adolescence.
Researchers have identified over a dozen new genes associated with abdominal aortic aneurysm, adding to the understanding of disease mechanisms. The study found that diastolic blood pressure is likely a significant factor in developing the condition.
A clinical trial of selpercatinib has shown promising results for patients with non-small cell lung cancer, achieving high response rates and prolonged survival. The drug specifically targets cancers driven by mutations in the gene RET, with minimal side effects.
A new interactive tool, ClubrootTracker, has been developed to help farmers locate and manage clubroot-infected areas. The tool groups the distribution of clubroot disease in one place, making it easier for farmers, researchers, and industry representatives to share information and plan a clubroot-free farm.
Tropical Storm Kujira's strongest storms were located near its center and in a band of thunderstorms on the western side, with cloud top temperatures as cold as minus 80 degrees Fahrenheit. NASA analyzed infrared imagery to determine the storm's strength and predict its potential for heavy rain.
Researchers have engineered a red-algae-like Rubisco enzyme into crops, doubling CO2-fixation rates. The breakthrough aims to increase crop production and improve photosynthesis efficiency.
