Closing critical gap in weather forecasting  

Scientists working on the next frontier of weather forecasting are hoping that weather conditions 3-to-4 weeks out will soon be as readily available as seven-day forecasts. Having this type of weather information--called subseasonal forecasts--in the hands of the public and emergency managers can provide the critical lead time necessary to prepare for natural hazards like heat waves or the next polar vortex.

Women who have C-sections are no more likely to have children who develop obesity than women who give birth naturally, according to a large study. The findings contradict several smaller studies that did find an association between C-section deliveries and offspring obesity but did not consider the numerous maternal and prenatal factors that the researchers did in this study.

A week in the dark rewires brain cell networks and changes hearing in adult mice  

New research reveals how a week in the dark rewires brain cell networks and changes hearing sensitivity in adult mice long after the optimal window for auditory learning has passed. With further study, cross-modal learning -- the manipulation of one sense to induce change in another sense -- could be used to help people with disabilities. For example, temporary sight deprivation might be used to help deaf and hearing-impaired people adapt to cochlear implants and hearing aids.

The slow solar wind seems to emerge from coronal holes along the sun's equator. Data also reveal strange magnetic field reversals that could be accelerating solar wind particles, and an unexpectedly dense shroud of comet dust around the sun.
