Can physical exercise enhance long-term memory?

A new study published in Brain Plasticity reports that running mice developed twice the normal number of new neurons and showed improved ability to distinguish between similar objects. This improvement in pattern separation is crucial for everyday memory tasks like remembering chess piece shapes or patterns on a board.

New strategy discovered for treating arthritis

Researchers at Queen Mary University of London have found that arthritic cartilage can be treated by a patient's own microvesicles, which can travel into cartilage cells and deliver therapeutic agents. The study suggests that these microvesicles could be a novel form of therapy for patients with cartilage damage due to various diseases.

Lactate for brain energy

Researchers from the University of Zurich have confirmed the existence of a concentration gradient of lactate between astrocytes and neurons in the intact mouse brain. The study provides new evidence for an exchange of lactate between different brain cells, supporting a 20-year-old hypothesis on brain energy metabolism.

People who rely on their intuition are, at times, less likely to cheat

A study by University of Missouri graduate student Sarah Ward found that people who trust their gut feelings are less likely to cheat after considering past immoral behavior. Participants in the experiment were asked to imagine acting immorally and then complete an unsolvable IQ test, with results showing that up to 23% cheated. The re...

Cataract surgery lessens patients' dizziness

After routine cataract surgery, older people experience significantly less dizziness due to improved vision. However, wearing multifocal glasses after surgery may negate this benefit, particularly for those with frailty or frequent spectacle changes.

Coming out of their evolutionary shells

A comprehensive genomic study of turtle shells has identified unique adaptations in genes that control hard cutaneous layers, dating back to the evolution of claws and feathers. The study also reveals a shared genetic organization between turtles and humans, highlighting the common ancestry of these defense mechanisms.

Cheesy products

Researchers from the University of Veterinary Medicine, Vienna tested over 100 raw milk cheeses purchased online and found that pathogenic bacteria like Listeria monocytogenes were present in two samples. Furthermore, more than half of the products lacked proper cooling, leading to increased bacterial growth during transport.

A sticky breakthrough

Researchers at UC Santa Barbara have designed a synthetic material that combines the key functionalities of interfacial mussel foot proteins, creating a single, low-molecular-weight, one-component adhesive. This breakthrough technology demonstrates record-high wet adhesion up to 10 times more effective than previous materials, with app...

New open-access data on paleofloods

Researchers have developed a new approach to recover flood frequency and magnitude data from temperate lakes, providing new sources of paleohydrological information. The study uses sediment dynamics to establish relationships between river discharge and deposit preservation, helping model and mitigate future flood risk.

Rice wins $2.4 million to study many-antenna wireless

The research aims to investigate the feasibility of using many-antenna base stations to serve multiple users simultaneously, addressing scalability and interference issues. By leveraging ArgosNet, a custom-built experimental test bed, the team will advance MIMO technology to meet the 1,000x data challenge in 5G networks.

Inkjet hologram printing now possible

Researchers at ITMO University have developed a method for producing vivid holographic images using an ordinary inkjet printer. The new technique uses colorless ink made of nanocrystalline titania, which can be deposited on special microembossed paper to create unique patterned images.

Safety last?

A study by Cornell researchers found that consumers tend to ignore food safety risks if they conflict with their preferred products, rather than changing their behavior. The study showed that risk information alone is not enough to get consumers to alter their behavior.
