Jupiter’s Great Red Spot Feeds on Smaller Storms

A flake of red peels away from Jupiter’s Great Red Spot during an encounter with a smaller anticyclone, as seen by the Juno spacecraft’s high resolution JunoCam on 12 February 2019. Although the collisions appear violent, planetary scientists believe they are mostly surface effects, like the crust on a crème brûlée.

The massive storm near the gas giant’s equator has been shrinking, but collisions with a series of anticyclones are likely only surface deep. The smaller storms cause chunks of red clouds to flake off, shrinking the larger storm in the process. But the new study found that these disruptions are “superficial.” They are visible to us, but they are only skin deep on the Red Spot, not affecting its full depth.

Researchers enhance Alzheimer’s disease classification through AI

Better detection of the disease may lead to earlier treatment, opportunity to participate in clinical trials. Warning signs for Alzheimer’s disease (AD) can begin in the brain years before the first symptoms appear. Spotting these clues may allow for lifestyle changes that could possibly delay the disease’s destruction of the brain.

“Improving the diagnostic accuracy of Alzheimer’s disease is an important clinical goal. If we are able to increase the diagnostic accuracy of the models in ways that can leverage existing data such as MRI scans, then that can be hugely beneficial,” explained corresponding author Vijaya B. Kolachalama, PhD, assistant professor of medicine at Boston University School of Medicine (BUSM).

Using an advanced AI (artificial intelligence) framework based on...

The Bald Truth: Altered Cell Divisions cause Hair Thinning

Schematic model of the distinct types of stem cell divisions determine HF homeostasis and aging.
Young HFSCs undergo symmetric cell divisions (SCDs) and asymmetric cell divisions (ACDs) to generate new bulge cells for their self-renewal and expansion. Whereas aged HFSCs provoke hemidesmosomal instability including COL17A1 and undergo stress response (SR) type ACDs to induce epidermal differentiation that triggers their delamination, thereby causing stepwise miniaturization of HFs and hair thinning and loss.

Researchers have identified a novel mechanism underlying hair thinning and loss during aging...
