Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts      (via sciencedaily.com)     Original source 

CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.

How coral reefs can survive climate change      (via sciencedaily.com)     Original source 

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.

Cryo conservation: A cool solution to saving species from extinction      (via sciencedaily.com)     Original source 

In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.
