New device gathers, stores electricity in remote settings

New device gathers, stores electricity in remote settings

Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery. …read more

Nasal spray safely treats recurrent abnormal heart rhythms, clinical trial suggests

A clinical trial showed that a nasal spray that patients administer at home, without a physician, successfully and safely treated recurrent episodes of a condition that causes rapid abnormal heart rhythms. The study provides real-world evidence that a wide range of patients can safely and effectively use the experimental drug, called etripamil, to treat recurrent paroxysmal supraventricular tachycardia (PSVT) episodes at home, potentially sparing them the need for repeated hospital trips for more invasive treatments. …read more

Common loons threatened by declining water clarity

Common loons threatened by declining water clarity

The Common Loon, an icon of the northern wilderness, is under threat from climate change due to reduced water clarity, according to a new study. The study followed up an earlier paper that showed substantial reproductive decline in the author’s study area in northern Wisconsin. …read more

Heat stress from ocean warming harms octopus vision

Heat stress from ocean warming harms octopus vision

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species. …read more

Stellar collisions produce strange, zombie-like survivors

Stellar collisions produce strange, zombie-like survivors

Densely packed, fast-moving stars at the Milky Way’s center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like ‘violent high fives’ while others are full-on mergers. …read more
