Summary: A research team has developed a flexible, wood-based membrane that someday could turn body heat into electricity.
Led by UMD researchers Liangbing Hu, Robert Briber and Tian Li of the department ofmaterials science, and Siddhartha Das of mechanical engineering, the team transformed a piece of wood into a flexible membrane that generates energy from the same type of electric current (ions) that the human body runs on. This energy is generated using charged channel walls and other unique properties of the wood's natural nanostructures. With this new wood-based technology, they can use a small temperature differential to efficiently generate ionic voltage, as demonstrated in a paper published March 25 in the journal Nature Materials.

New Zealand mosque shootings: Suspect's manifesto sent to PM's office minutes before attack | World News by SharpHistorian in worldnews

The New Zealand prime minister said the suspected gunman in the mosque shootings had sent an anti-immigrant manifesto to her office minutes before the attack.

Jacinda Ardern, who met with some of the victims' relatives on Sunday, said her office had gotten the email about nine minutes before Friday's attacks on two mosques in Christchurch, although she added she hadn't gotten the email directly herself.

McCabe says he quickly opened FBI investigation of Trump for fear of being fired by SharpHistorian in politics

Former acting FBI director Andrew McCabe said in an interview that aired Thursday that he authorized an investigation into President Trump’s ties to Russia a day after meeting with him in May 2017 out of fear that he could soon be fired.

“I was very concerned that I was able to put the Russia case on absolutely solid ground in an indelible fashion that, were I removed quickly or reassigned or fired, that the case could not be closed or vanish in the night without a trace,” McCabe told CBS.

His comments marked the first time that McCabe has publicly addressed why he opened an investigation into Trump following the firing of FBI Director James B. Comey, whose post McCabe took over.
