A recent study published in Investigative Genetics found that the genomic diversity of the Dutch population follows a southeast-to-northwest gradient, with the population separated into four geographic groups. The researchers propose that this pattern is due to recent movement within the last 2000 years, rather than ancient events.
In a surprise twist, female strawberry poison frogs in Costa Rica prioritize the nearest singing male over physical appearance and vocal quality. The research found that females fail to discriminate between different call rates or frequencies, instead opting for the closest speaker.
Researchers found that depressed individuals express personal goals in vague terms, such as 'to be happy,' rather than specific objectives like improving a running time. This reduced specificity may be linked to the motivational deficits seen in depression, and could inform more effective psychotherapeutic approaches.
