Researchers have discovered, in the mouse brain, that a key metabolic enzyme works directly within the nucleus of neurons to turn genes on or off when new memories are being established.

How to capture videos of brains in real time http://ift.tt/2sTaUgJ Individual neurons firing within a volume of brain tissue (credit: The Rockefeller University) A team of scientists has peered into a mouse brain with light, capturing live neural activity of hundreds of individual neurons in a 3D section of tissue at video speed (30 Hz) in a single recording for the first time. Besides serving as a powerful research tool, this discovery means it may now be possible to “alter stimuli in real time based on what we see going on in the animal’s brain,” said Rockefeller University’s Alipasha Vaziri , senior author of an open-access paper published June 26, 2017 in Nature Methods . By dramatically reducing the time and computational resources required to generate such an image, the algorithm opens the door to more sophisticated experiments, says Vaziri, head of the Rockefeller Laboratory of Neurotechnology and Biophysics . “Our goal is to better understand brain function by monitor

Kate McKinnon and Alec Baldwin break character to urge people to vote http://ift.tt/2eCjDNe In its last show before the 2016 Presidential election, Saturday Night Live checked in with Alec Baldwin’s Donald Trump and Kate McKinnon’s Hillary Clinton one final time before Tuesday, with both actors breaking character to urge voters to head to the polls. The cold open started by poking at the intense focus on Clinton’s e-mails. The interviewer dismisses questions come up about FBI, Vladimir Putin, and the KKK, even as Baldwin plants a kiss on each representative of each group and as McKinnon gets more and more annoyed with the pivot back to her e-mails. It’s a funny sketch, and it gets funnier as both actors break character, unable to keep up with the ridiculousness of what they’re doing. “I just feel gross all the time,” Baldwin remarked. This leads to a strange, but ultimately fitting bit as McKinnon leads Baldwin out the building, where we’re treated to a montage of the pair da
