How a low-calorie diet could extend lifespan

A recent study published in ACS' Journal of Proteome Research found that calorie restriction can help delay age-related disorders. The researchers discovered that mice on low-calorie diets had reduced oxidative stress, improved lipid metabolism, and altered gut-microbial metabolites compared to those on high-calorie diets.

New clues about the aging brain's memory functions

A European study led by Umea University Professor Lars Nyberg found a positive link between the dopamine D2 receptor and long-term episodic memory, which often declines with age. The research suggests that impairment of the dopamine system may play a crucial role in understanding age-related cognitive decline.

Watching a forest breathe

Researchers obtained detailed measurements of carbon exchange in a temperate deciduous forest, revealing that trees exhale less CO2 during the day than previously thought. The study confirmed that forest photosynthesis doesn't decline over the course of summer, contrary to conventional wisdom used in climate models.

Nutrition labels on dining hall food: Are they being used? By who?

A study found that university students who practice health-promoting behaviors like tracking food intake and exercising frequently are more likely to use nutrition information on dining hall food. Only 20% of students used the labels, despite high label awareness rates.

The irony of awkward

A recent study published in Developmental Psychology found that individuals who engage in problematic media, such as violent video games, gambling, or pornography, become more withdrawn over time. The research suggests that avoidant individuals are particularly at risk for negative outcomes, including depression and crime, when they co...

Unlocking the secrets of nerve regeneration

Researchers discovered that cutting parallel fibres in normal mice results in three distinct phases of degeneration, hypertrophy, and remodelling. In contrast, mice lacking the GluD2 receptor remain stuck in the degenerative phase. This suggests that GluD2 plays a crucial role in regulating nerve regeneration.

Saved by the sun

A new solar-powered oxygen delivery system, developed by UAlberta, is providing concentrated oxygen to children with severe pneumonia in Ugandan hospitals. The system, which uses solar energy and batteries, has shown to be as effective as conventional oxygen delivery methods.

No need in supercomputers

A team of Russian physicists used a personal computer with GPU to solve complicated integral equations of quantum mechanics, previously only solvable with expensive supercomputers. They achieved speeds up to 15 minutes for calculations that took days on supercomputers.
