The Molecular Bond That Helps Secure Your Memories
To find out if KIBRA and PKMζ work together in response to synaptic activity, the researchers used a technique that makes interacting proteins glow. When they applied electrical pulses to hippocampal slices, glowing dots of evidence appeared: Following bursts of synaptic activity that produced long-term synaptic strengthening, a multitude of KIBRA-PKMζ complexes formed, and they… Continue reading The Molecular Bond That Helps Secure Your Memories
Turning PA’s Poor Rankings into a Winning GOP Agenda
Pennsylvania’s latest national rankings are not just embarrassing – they’re a policy indictment. But for Republicans, they also offer something else: a clear political opportunity. U.S. News & World Report ranks Pennsylvania 41st out of 50 states. Of the six states bordering the Commonwealth, five ranked higher. Only West Virginia fared worse.

For a while there was… Continue reading How Can We Know If an Asteroid Will Hit Earth?
What Happens When AI Starts To Ask the Questions?
When Mario Krenn was studying quantum physics at the University of Vienna, he was trained in a particular way of designing new experiments: “You go to a blackboard, and you think very hard,” he said. In 2014, Krenn was trying to come up with a way to observe a particular quantum state. A typical setup… Continue reading What Happens When AI Starts To Ask the Questions?
