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.

AI, open science, and the extreme weather pandemic: Takeaways from SXSW 2024

Every year, creatives, innovators, and visionaries from around the world gather in Austin, Texas for a celebration of human creativity at South by Southwest (SXSW). The week-long conference offers a vibrant convergence of tech, film, music, education, and culture. Over 450 sessions, from keynotes and feature speakers to panels and workshops, enable participants to encounter cutting-edge ideas, discover new interests, and network with other professionals from across industries. Among the topics of focus for this year’s SXSW was climate change. A dedicated ‘track’, or lineup, of sessions explored the most promising ideas on mitigating or adapting to the effects of global warming and in-depth coverage of the consequences of unpredictable weather patterns and rising ocean levels.
