Every summer, cownose rays stream into Chesapeake Bay to mate and give birth to their pups. In autumn they disappear, presumably to migrate south, but no one knew for certain where they spent winter. Now, after a three-year tagging study, scientists have solved the mystery. Cownose rays all along the Atlantic winter near Cape Canaveral, Florida, and it is likely they return to the same spots each summer.
Study describes progress toward 'humanized' mouse: Adding second stem-cell type improves model, allows better testing of cancer immunotherapies.
Chemists have unlocked the secrets of polyisobutylene's reaction mechanism. The group's findings could potentially be used to design different catalysts and to control the reaction — and hence, the potential range of products.
People are falling into a trap of greater inactivity during middle age, according to new research.
Researchers find that the 'noise' in the brain can be attributed to fluctuations in internally generated signals such as attention.
Researchers have discovered a molecular link between aging and a major genetic cause of both amyotrophic lateral sclerosis and frontotemporal dementia, two related neurodegenerative diseases with shared genetic risk factors. The findings reveal possible new targets for treatment of these and other neurodegenerative diseases.
Researchers have found that toddlers who had poor self-regulation skills — the ability to control their behaviors and emotions — went on to have lower BMIs as preschoolers if their mothers engaged with them during playtime and then helped direct them during clean up.
British Columbia is on fire. In this Canadian province, 56 wildfires 'of note' are active and continuing to blow smoke into the skies overhead.
Two new dinosaurs — dubbed Bannykus and Xiyunykus — have been discovered in north China. Researchers say the animals, which show adaptations related to eating insects that live in colonies, are alvarezsaurs: the dinosaurian analogue to today's aardvarks and anteaters.
Researchers have discovered an internal messaging system that plants use to manage the growth and division of their cells. Understanding this negative-feedback loop that helps plants survive under harsh conditions could enable innovations in agriculture, forestry and conservation as climate change takes hold.
