Scientists rejuvenate mouse brains with ketamine or flickering light
In defining periods of development, the brain re-organizes connections between its neurons more freely than in its adult form. Researchers have now discovered two methods to reopen such plasticity: repeated ketamine anesthesia and non-invasive 60 her.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»

Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Sloth survival under threat due to climate change, study finds
A new PeerJ study has revealed that sloths, the famously slow-moving creatures of Central and South America, may face existential threats due to climate change. The research, conducted by scientists studying the metabolic response of sloths to rising.....»»
Wall lizards shed light on how animals prevent harm in territorial disputes
A study appearing in Behavioral Ecology shows that in male wall lizards, certain behaviors have a greater influence on the way they resolve territorial disputes than their size and coloration......»»
Advanced data shed light on gravitational basins of attraction that shape the movement of galaxies
A new study has mapped out the gravitational basins of attraction in the local universe, offering fresh insights into the large-scale cosmic structures that shape the movement of galaxies. The study has been published in Nature Astronomy......»»
NASA"s Artemis science instrument gets tested in moon-like sandbox
On Sept. 9 and 10, scientists and engineers tested NASA's LEMS (Lunar Environment Monitoring Station) instrument suite in a "sandbox" of simulated moon regolith at the Florida Space Institute's Exolith Lab at the University of Central Florida in Orla.....»»
Dark matter could have slight interaction with regular matter, study suggests
The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. It's why, for example, we c.....»»
Transforming caragana waste into nutritious ruminant feed
In an advance for agricultural waste management, scientists from the Chinese Academy of Sciences have devised a method to convert Caragana korshinskii Kom. waste, a common forestry byproduct in China, into a potential ruminant feed. The research, pub.....»»
