Geisel study examines variation in intensity of fracture-associated prescription drug use

A new Geisel-led study found substantial regional variation in the intensity of fracture-associated drug (FAD) use among long-term care facility residents, with areas experiencing higher FAD use having higher hip fracture rates. The study analyzed Medicare data and prescription records, revealing a 12% difference in FAD prescribing ran...

Genetic study of Lewy body dementia supports ties to Alzheimer's and Parkinson's diseases

A genetic study of Lewy body dementia suggests that the disease is caused by a spectrum of problems seen in both Alzheimer's and Parkinson's diseases. Five genes have been identified as critical to the development of Lewy body dementia, with variations in these genes also linked to increased risk of Alzheimer's and Parkinson's diseases.

Answer quickly to be believed

A study published by the American Psychological Association found that response speed is an important cue on which people base their sincerity inferences. Participants rated delayed responses as less sincere than immediate ones, regardless of the question's seriousness.

Leaders valued over managers, regardless of fit

A recent study from Cornell University-led research highlights the risk of overvaluing prototypical leaders and undervaluing management skills. Participants preferred to hire a CEO with strong leadership qualities over those with more managerial expertise, despite the organization's need for management skills.

Crocodile evolution rebooted by Ice Age glaciations

A recent study led by McGill University found that the Pacific and Caribbean crocodile populations have been separated for approximately 100,000 years, contradicting previous expectations of 3 million years. This discovery was made possible by reconstructing Ice Age sea levels and analyzing genetic variations in the crocodiles' genomes.

Bacteria and algae get rides in clouds

Researchers from Rutgers University discovered that clouds can carry bacteria and algae, which could impact human health and ecosystems. The study found various types of algae, including cyanobacteria, in cloud water and rainwater collected from France, highlighting the need for further research on these microorganisms.
