Helping your mother make pancakes when you were three…riding your bike without training wheels…your first romantic kiss: How do we retain vivid memories of long-ago events? As described in a paper published in Neuron, researchers at Albert Einstein College of Medicine have found the explanation.

“The ability to learn new information and store it for long periods is one of the brain’s most remarkable features,” said Robert H. Singer, Ph.D., a co-corresponding author of the paper. “We’ve made a startling discovery in mice regarding the molecular basis for making those long-term memories.” Dr. Singer is professor of cell biology and in the Dominick P...

Webb Reveals Early-Universe Prequel to Huge Galaxy Cluster

Various multi-color galaxies on a black background, with specific close-ups of 7 faint red galaxies in a column on right
The seven galaxies highlighted in this James Webb Space Telescope image have been confirmed to be at a distance that astronomers refer to as redshift 7.9, which correlates to 650 million years after the big bang. This makes them the earliest galaxies yet to be spectroscopically confirmed as part of a developing cluster.

Every giant was once a baby, though you may never have seen them at that stage of their development. NASA’s James Webb Space Telescope has begun to shed light on formative years in the history of the universe that have thus far been beyond reach: the formation and assembly of galaxies...

Too Much Insulin can be as Dangerous as Too Little

Millions of Americans use insulin injections to boost levels and treat diabetes, but too much insulin can be deadly too. Researchers have identified a key player in preventing “insulin shock” that might also prove an effective alternative to the hormone. Agamatrix

Researchers describe a key player in the defense mechanism that safeguards against excessive insulin in the body, which can be as harmful as too little. Just over a century has passed since the discovery of insulin, a time period during which the therapeutic powers of the hormone have broadened and refined. Insulin is an essential treatment for type 1 diabetes and often for type 2 diabetes, as well. Roughly 8.4 million Americans use insulin, according to the American Diabetes Association.

One hundred years of research ...

Revolutionary design could combine superconductor levitation, lossless electricity transmission, and liquid hydrogen transportation into one system. Superconductors can conduct electricity without any resistance or power loss, and they can effortlessly cause magnets to levitate above them. These properties would make superconductors useful for high-speed trains or long-distance power transmission, except for one glaring problem: superconductors only work at low temperatures, more than a hundred degrees below zero.

This one requirement makes building a hyperefficient electrical grid or high-speed rail netwo...
