Older adults who start to experience bad dreams or nightmares could be exhibiting the earliest signs of Parkinson’s disease, say researchers.

Otters learn skills from each other — but they also solve some mysteries alone, new research shows.

Scientists find evidence that the immune protein CSF1 may contribute to feelings of anxiety during alcohol withdrawal.

Scientists find that holes can also improve technology, including medical devices. The article describes an entirely new way to make a solar cell: by etching holes in the top layer to make it porous.

In a ‘seismological wind tunnel,’ engineers demonstrate the impact of rock gouge — ground-up rock along a fault boundary — on earthquake propogation.

Scientists have revealed the effect of temperature on water in protein-ligand interactions, providing a way to produce structures for drug discovery that are less biased by freezing artifacts.

What’s the relationship between people’s perception of beauty and animals’ conservation needs? According to a machine-learning study, the reef fishes that people find most beautiful tend to be the lowest priority for conservation support.

Current technologies to modulate light in free space are bulky, slow, static, or inefficient. Now researchers have developed a compact and tunable electro-optic modulator for free space applications that can modulate light at gigahertz speed.

Researchers found that administration of the drug rapamycin in mice was associated with increased beta-amyloid plaques. This is one of the hallmark pathologies of Alzheimer’s disease. The study authors caution that rapamycin’s effects in beta-amyloid-a…
