High-intensity exercise induces brain-protective effects that have the potential to not just slow down but possibly reverse the neurodegeneration associated with Parkinson’s disease, a new pilot study suggests.

Prior research has shown that many forms of exercise are linked to improved symptoms of Parkinson’s disease. But there has been no evidence that hitting the gym could create changes at the brain level. Now, a small proof-of-concept study involving 10 patients showed that high-intensity aerobic exercise preserved dopamine-producing neurons, the brain cells that are most vulnerable to destruction in patients with the disease.

In fact, after six months of exercise, the neurons actually had grown healthier and produced stronger dopamine signals. Dopamine is a chemical that helps brain cells communicate with one another. The researchers published their findings in npj Parkinson’s Disease on February 9.

“There’s a muon right there,” says Tioukov, pointing to a squiggly line he’s blown up using a microscope.

After months of painstaking analysis, Tioukov and his team are able to put together a three-dimensional model of that hidden burial chamber, closed to human eyes for centuries, now opened thanks to particle physics.

What seems like science fiction is also being used to peer inside the pyramids in Egypt, chambers beneath volcanoes, and even treat cancer, says Professor Giovanni De Lellis.

A researcher at The University of Texas at Austin has developed a mug-sized device that can clean water using only a small jolt of electricity. The device could be used to help get drinking water to people left stranded by extreme weather events.

Dr. Donglei “Emma” Fan — an associate professor in the Walker Department of Mechanical Engineering at the Cockrell School of Engineering — along with her research team, was able to create the device using a specially designed “branched” electrode, now patented.

The electrode, when electrified, created a field that E. coli and other bacterial cells are attracted to, causing them to “swim” into the electrode branches. In lab experiments, the device successfully removed 99.997% of E. coli bacteria from water samples in just 20 minutes.

Quantum researchers uncover important implications for quantum technology.

In a recent publication in Nature Physics, the LSU Quantum Photonics Group offers fresh insights into the fundamental traits of surface plasmons, challenging the existing understanding. Based on experimental and theoretical investigations conducted in Associate Professor Omar Magaña-Loaiza’s laboratory, these novel findings mark a significant advancement in quantum plasmonics, possibly the most noteworthy in the past decade.

Rethinking Plasmonic Behavior

Jupiter is iconic, with its swirls of water and ammonia vapor that characterize its outer surface and its distinctive Giant Red Spot, a gigantic storm raging across its face.

But its mysteries abound — such as Jupiter’s strange and asymmetrical magnetic field, which has a strong area of magnetism in its equator called the “Great Blue Spot” — blue because that’s how it’s color-coded in maps tracing the magnetic field.

In an effort to understand the planet’s magnetic field better, a team of American scientists from Harvard University, the California Institute of Technology, NASA and the Southwest Research Institute in San Antonio, Texas studied an atmospheric jet — a high speed current in the gas giant’s atmosphere — in the Great Blue Spot. Their finding? It’s a dynamic system that fluctuates every four years or so.
