Asthma has been associated with a lowered risk of brain tumors, and researchers now think they know why: Immune cells activated under conditions of asthma are less able to promote the growth of brain tumors. The findings could lead to new therapeutic approaches.

Scientists have measured records of wood flowing to reservoirs and coastal regions to estimate the magnitude of global wood movement.

New research into the design of catalysts has shown that hydrogen can be cleanly produced with much greater efficiency and at a lower cost than is possible with current commercially available catalysts.

Too often, strategies proven in research studies to reduce pediatric obesity are never implemented in the 'real world.' Researchers describe a school-based program that gets these interventions across the finish line by inviting schools to tailor them to their own needs. Thanks to this flexible approach, 200 schools in South Carolina have signed on and seen improvements in both health and educational outcomes.

When cells within a single tumor differ in terms of their genetic makeup, this is referred to as intratumor heterogeneity. Researchers have been able to reconstruct the process by which this genetic heterogeneity develops in neuroblastoma, a type of cancer which primarily affects young children. According to their findings, the genetic makeup of individual tumors shows marked spatial and temporal variability.

Computer engineers have developed a new AI method for accurately predicting the power consumption of any type of computer processor more than a trillion times per second while barely using any computational power itself. Dubbed APOLLO, the technique has been validated on real-world, high-performance microprocessors and could help improve the efficiency and inform the development of new microprocessors.

A global assessment assessed rice yields and efficiency in 32 rice cropping systems. The study concluded that there is still substantial room to increase rice production while reducing the negative environmental impacts. A leading agronomist describes the study as 'the most comprehensive global evaluation of production systems for a major staple crop, (one that) will set the standard for future global comparison.'

A new study shows that machine learning techniques can offer powerful new tools for advancing personalized medicine, care that optimizes outcomes for individual patients based on unique aspects of their biology and disease features.

A global hacker 'red team' and rewards for hunting algorithmic biases are just some of the recommendations from experts who argue that AI faces a 'tech-lash' unless firm measures are taken to increase public trust.

A study has discovered how late-onset retinal degeneration can develop and a surprising potential therapeutic -- metformin.

Across the U.S. road crews dump around 25 million metric tons of sodium chloride -- much like table salt -- to unfreeze roads each year and make them safe for travel.
