Ultrasound beam triggers ‘nanodroplets' to deliver drugs at exactly the right spot

Conventional drug delivery is inefficient and imprecise. Through a series of preclinical experiments, researchers from the University of Utah have optimized a novel, targeted method of delivery through nanodroplet carriers, which are triggered to release their drug at exactly the desired spot by a focused beam of ultrasound. Their results showed that nanodroplets with a core of perfluorooctylbromide are stable, efficient in delivery, and well tolerated. Clinical experiments are likely to follow.

How older people explore new spaces could suggest cognitive decline and dementia

Aging people commonly show a decline in navigation ability, and this has generally been attributed to worsening spatial memory. But now, researchers from the US have shown for the first time that this decline is partly driven by changes in typical exploration behavior by middle age. In a maze learning task, middle-aged people were less efficient explorers than young people. This discovery could have applications in the clinical diagnosis and therapy of cognitive decline and dementia.

Clues to mysterious disappearance of North America’s large mammals 50,000 years ago found within ancient bone collagen

Dr Mariya Antonosyan, Dr Torben Rick, and Prof Nicole Boivin are co-authors of a new Frontiers in Mammal Science article in which they used new methods to identify fossil bone fragments housed at the Smithsonian’s National Museum of Natural History. The insights they gained could help scientists better understand the causes and consequences of large mammal extinction.

Babies in the womb exposed to two languages hear speech differently when born

Researchers have shown for the first time that newborns of monolingual mothers respond differently to playback of a carefully selected sound stimulus than newborns of bilingual mothers. The findings suggest that bilingual newborns are sensitive to a wider range of acoustic variation of speech, at the cost of being less selectively tuned in to any single language. These results underscore the importance of prenatal exposure for learning about speech.
