Quantum computers, quantum cryptography and quantum (insert name here) are often in the news these days. Articles about them inevitably refer to entanglement, a property of quantum physics that makes all these magical devices possible.

Einstein called entanglement “spooky action at a distance,” a name that has stuck and become increasingly popular. Beyond just building better quantum computers, understanding and harnessing entanglement is also useful in other ways.

Researchers at Johns Hopkins Medicine have successfully used a laser-assisted imaging tool to “see” what happens in brain cells of mice learning to reach out and grab a pellet of food. Their experiments, they say, add to evidence that such motor-based learning can occur in multiple areas of the brain, even ones not typically associated with motor control.

“Scientists should be looking at the entire brain to understand specific types of learning,” says Richard Huganir, Ph.D., Bloomberg Distinguished Professor and Director of the Solomon H. Snyder Department of Neuroscience at the Johns Hopkins University School of Medicine. “Different parts of the brain contribute to learning in different ways, and studying brain cell receptors can help us decipher how this works.”

The work, say the researchers, may ultimately inform efforts to develop treatments for learning-based and neurocognitive disorders.

Scientists have uncovered a new kind of electrical process in the human brain that could play a key role in the unique way our brains compute.

Our brains are computers that work using a system of connected brain cells, called neurons, that exchange information using chemical and electric signals called action potentials. Researchers have discovered that certain cells in the human cortex, the outer layer of the brain, transmit signals in a way not seen in corresponding rodent cells. This process might be important to better understanding our unique brains and to improving programs that are based on a model of the human brain.

Breakthrough research shows that type 2 diabetes occurs when fat from the liver overspills into the pancreas and confirms that weight loss can reverse it.

A newly published study has described the successful results in mice of a novel vaccine designed to prevent neurodegeneration associated with Alzheimer’s disease. The researchers suggest this “dementia vaccine” is now ready for human trials, and if successful could become the “breakthrough of the next decade.”

The new study, led by the Institute for Molecular Medicine and University of California, Irvine, describes the effect of a vaccine designed to generate antibodies that both prevent, and remove, the aggregation of amyloid and tau proteins in the brain. The accumulation of these two proteins is thought to be the primary pathological cause of neurodegeneration associated with Alzheimer’s disease.

The research revealed the vaccine led to significant decreases in both tau and amyloid accumulation in the brains of bigenic mice engineered to exhibit aggregations of these toxic proteins. Many prior failed Alzheimer’s treatments over the past few years have focused individually on either amyloid or tau protein reductions, but growing evidence suggests a synergistic relationship between the two toxic proteins may be driving neurodegeneration. Hence the hypothesis a combination therapy may be the most effective way to prevent this kind of dementia.

No one really knows what happens inside an atom. But two competing groups of scientists think they’ve figured it out. And both are racing to prove that their own vision is correct.

Here’s what we know for sure: Electrons whiz around “orbitals” in an atom’s outer shell. Then there’s a whole lot of empty space. And then, right in the center of that space, there’s a tiny nucleus — a dense knot of protons and neutrons that give the atom most of its mass. Those protons and neutrons cluster together, bound by what’s called the strong force. And the numbers of those protons and neutrons determine whether the atom is iron or oxygen or xenon, and whether it’s radioactive or stable.
