Medical Xpress / Alzheimer's disease can be reversed in animal models to achieve full neurological recovery

For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery. Despite billions of dollars spent on decades of research, ...

Phys.org / Raindrops form 'sandballs' as they roll downhill, contributing more to erosion than previously thought

What happens as a raindrop impacts bare soil has been fairly well-studied, but what happens to raindrops afterward is poorly understood. We know that the initial splash of raindrops on soil contributes to erosion, but a new ...

Phys.org / The chaotic 'Dracula's Chivito': Hubble reveals largest birthplace of planets ever observed

Astronomers using NASA's Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young star. For the first time in visible light, Hubble has revealed the disk is unexpectedly chaotic and ...

Medical Xpress / Foods with healthy-sounding buzzwords could be hiding added sugar in plain sight

Many consumers feel pride in avoiding the glazed pastries in the supermarket and instead opting for "all natural" granola that comes packed with extra protein. Same goes for low-fat yogurts "made with real fruit," "organic" ...

Phys.org / Detecting the hidden magnetism of altermagnets

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the sublattices are linked by simple ...

Phys.org / Study shows the 2008 recession caused people to identify with a lower class

Class identity, which is how individuals view their economic and social positions in relation to others, has wide-ranging effects on people's well-being, thoughts, and behavior. Previous studies have shown that people who ...

Phys.org / Observations catch galaxy cluster in the process of merging

Astronomers have used the Keck Observatory's DEIMOS multi-object spectrograph to observe a nearby galaxy cluster designated RXC J0032.1+1808. As a result, they found that the cluster undergoes a major merging event. The finding ...
