Scientists win historic Nobel chemistry prize for ‘genetic scissors’

Scientists win historic Nobel chemistry prize for ‘genetic scissors’

Science
Two scientists have been awarded the 2020 Nobel Prize in Chemistry for developing the tools to edit DNA.Emmanuelle Charpentier and Jennifer Doudna are the first two women to share the prize, which honours their work on the technology of genome editing. Their discovery, known as Crispr-Cas9 "genetic scissors", is a way of making specific and precise changes to the DNA contained in living cells.They will split the prize money of 10 million krona (£861,200; $ 1,110,400).Biological chemist Pernilla Wittung-Stafshede, commented: "The ability to cut DNA where you want has revolutionised the life sciences."Not only has the women's technology been transformative for basic research, it could also be used to treat inherited illnesses.Prof ...

Doudna have won the Nobel Prize in chemistry for developing a method of genome editing likened to “molecular scissors” that offer the promise of one day curing genetic diseases.The recipients were announced Wednesday in Stockholm by the Royal Swedish Academy of Sciences.“There is enormous power in this genetic tool, which affects us all,” said Claes Gustafsson, chair of the Nobel Committee for Chemistry. "It has not only revolutionised basic science, but also resulted in innovative crops and will lead to ground-breaking new medical treatments....
Army researchers improve battery safety with new cathode chemistry

Army researchers improve battery safety with new cathode chemistry

Science
May 10 (UPI) -- Scientists with the U.S. Army have developed a new type of cathode chemistry that makes batteries safer and more efficient. Currently, soldiers must regularly carry batteries weighing between 15 and 20 pounds. But thanks to a new type of cathode and electrolyte, soldiers could soon be carrying safer and more efficient batteries weighing half as much. Army researchers were able to boost lithium-ion battery energy density by using a totally aqueous electrolyte. The electrolyte is free of transition metal and boasts high capacity energy storage. "Such a high energy, safe and potentially flexible new battery will likely give the Soldiers what they need on the battlefield: reliable high energy source with robust tolerance against abuse," Kang Xu, senior scientist at the U.S. Ar...

Helpline to tackle bullying in chemistry

Science
Bullying and harassment is such a problem in the world of chemistry that a dedicated helpline is being set up for victims, a scientific body says.The Royal Society of Chemistry says people were being denied opportunities because of "a culture of secrecy" and the 'unchecked power of managers'.The research showed both men and women have been bullied and harassed by colleagues.But it was mostly women who were discriminated against.It's hoped the helpline will increase the number of women chemists.'Rock stars'Professor Rachel O'Reilly is now Head of the Chemistry School at the University of Birmingham.But, in previous roles, she says she's "had issues or witnessed others" facing discrimination."I've been called 'little woman' a lot." ...
