New insights into how the CRISPR immune system evolved

Although CRISPR-Cas has found many uses in biotechnology and medicine, it originates in nature, where it functions as a microbial immune system. Scientists shed new light on how CRISPR-Cas emerged early during the development of life on Earth, as well as how this immune system is constantly adapting to new challenges.

Engineering researcher receives EPSCoR grant for electrocatalysis work

(University of Arkansas) University of Arkansas engineering professor Lauren Greenlee received a $750,000 award from the Department of Energy to investigate the chemical and electronic structure of iron and oxygen atoms. The research will improve battery materials, water electrolysis for hydrogen production, polymer recycling and water treatment.

Stable catalysts for new energy

Looking for the perfect catalyst is not only about finding the right material, but also about its orientation. Depending on the direction in which a crystal is cut and which of its atoms it thus presents to the outside world on its surface, its behavior can change dramatically.

New light on polar explorer’s last hours

Chemical analyzes of a black spot in a diary shed new light on the destiny and tragic death of legendary Inuit polar expedition member Jørgen Brønlund in Northeast Greenland in 1907.

Turning waste plastic into carbon nanotubes to transmit electricity

(Swansea University) Scientists at Swansea University are extracting carbon atoms found in waste plastics and turning them into a nanotube format that can be used for the transmission of electricity. They are producing plastic electric cables without the copper wire inside them, which can be used in residential and industrial construction.The Welsh government is investing in the plastics upscaling project, which has the potential to create highly-skilled jobs in Wales.
