Cognitive Improving Effects by Highbush Blueberry (Vaccinium crymbosum L.) Vinegar on Scopolamine-Induced Amnesia Mice Model

Dementia affects millions of people worldwide, robbing them of their ability to think, remember and live as they once did. In the search for new ways to fight cognitive decline, scientists report in ACS’ Journal of Agricultural and Food Chemistry that blueberry vinegar might offer some help. They found that the fermented product could restore cognitive function in mice.

Recent studies have shown that the brains of people with Alzheimer’s disease, the most common form of dementia, have lower levels of acetylcholine and its receptors. Research has also demonstrated that blocking acetylcholine receptors disrupts learning and memory...

Cosmic rays interacting with the Earth’s atmosphere producing ions that helps turn small aerosols into cloud condensation nuclei — seeds on which liquid water droplets form to make clouds. A proton with energy of 100 GeV interact at the top of the atmosphere and produces a cascade of secondary particles who ionize molecules when traveling through the air. One 100 GeV proton hits every m2 at the top of the atmosphere every second. Credit: Illustration: H. Svensmark/DTU

Breakthrough in understanding of how cosmic rays from supernovae can influence Earth’s cloud cover and thereby climate...

Scientists at Queen’s University Belfast have led worldwide investigations into a mysterious object that passed close to Earth after arriving from deep interstellar space. Since the object was spotted in October, Professor Alan Fitzsimmons and Dr Michele Bannister from the School of Mathematics and Physics at Queen’s University have led an international team of astronomers to piece together a profile of the strange visitor, which has been named `Oumuamua...

Lawrence Livermore National Laboratory (LLNL) scientists and engineers have developed a “brain-on-a-chip” device aimed at testing and predicting the effects of biological and chemical agents, disease or pharmaceutical drugs on the brain over time without the need for human or animal subjects.

The device, part of the Lab’s iCHIP (in-vitro Chip-Based Human Investigational Platform) project, simulates the central nervous system by recording neural activity from multiple brain cell types deposited and grown onto microelectrode arrays...
