Farms following soil-friendly practices grow healthier food, study suggests

Posted: 24 Feb 2022 09:52 AM PST

An experiment conducted on 10 farms across the U.S. suggests that crops from farms following soil-friendly practices for at least five years have a healthier nutritional profile than the same crops grown on neighboring, conventional farms. Researchers believe soil microbes and fungi boost certain beneficial minerals, vitamins and phytochemicals in the crops.

New research suggests that leatherback turtles entangled in fishing gear have a better chance of survival if the incident is reported quickly, giving trained responders the opportunity to fully disentangle the animals.

'Workhorse' of photovoltaics in tandem with perovskite

Posted: 24 Feb 2022 08:26 AM PST

So-called PERC cells are used in mass production of silicon solar cells, they are considered the workhorses of photovoltaics, dominating the market. Now two teams have shown that such standard silicon cells are also suitable as a basis for tandem cells with perovskite top cells. Currently, the efficiency of the tandem cell is still below that of optimised PERC cells alone, but could be increased to up to 29.5% through targeted optimization. The research was funded by the German Federal Ministry of Economics as part of a joint project.

An experiment in Panama's Parque Natural Metropolitano and Gamboa revealed that agoutis were less likely to disperse and pilfer seeds in sites where ferocious felines roam.

The last day of the dinosaurs

Posted: 23 Feb 2022 08:12 AM PST

The asteroid which killed nearly all of the dinosaurs struck Earth during springtime. This conclusion was drawn by an international team of researchers after having examined thin sections, high-resolution synchrotron X-ray scans, and carbon isotope records of the bones of fishes that died less than 60 minutes after the asteroid impacted.

Onset of modern sea level rise began in 1863, study finds

Posted: 18 Feb 2022 12:30 PM PST

Scientists have found that modern rates of sea level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt. The study, which used a global database of sea-level records spanning the last 2,000 years, will help local and regional planners prepare for future sea-level rise.
