A new view of visual system development

Researchers at Duke University have discovered that spontaneous neural activity plays a key role in organizing the visual cortex, contradicting current theories on ocular dominance. The study used young ferrets with closed eyes to record brain activity patterns and found that input from one eye drives the entire system.

Religious attendance linked to lower mortality in elderly

A study of nearly 4,000 elderly North Carolinians found that frequent religious attenders were 46% less likely to die over a six-year period. They also experienced greater social support and reported better mental health, which may contribute to lower mortality rates.

Ratchet effect solves one problem in superconductors

Researchers propose using an alternating current to pattern a sawtooth-like structure on a superconductor, directing vortices away from the device. This method avoids sophisticated material processing and can be used in both low-temperature and high-temperature superconductors.

Two scientists make case against ice on the moon

Two Stanford University scientists argue that large amounts of water ice are unlikely on the Moon, suggesting an alternative explanation involving the reaction of lunar dust with hydrogen and oxygen. They propose that the Lunar Prospector crash could produce a plume of water vapor and hydroxyl ions without ice being present.

Genetically engineered organisms: Hazardous or beneficial

A symposium by the Ecological Society of America explores the delicate balance between the benefits and risks of genetically engineered organisms. The discussion will cover case studies on engineered plants, arthropods as tools in disease control, and risk assessment in ecosystems.
