| Asthma may reduce risk of brain tumors -- but how? Posted: 10 Dec 2021 12:50 PM PST 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. |
| Disrupting flow of wood from rivers to oceans impacts marine environments Posted: 10 Dec 2021 11:07 AM PST Scientists have measured records of wood flowing to reservoirs and coastal regions to estimate the magnitude of global wood movement. |
| Researchers develop advanced catalysts for clean hydrogen production Posted: 10 Dec 2021 11:07 AM PST 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. |
| Getting childhood obesity initiatives across the finish line Posted: 10 Dec 2021 08:30 AM PST 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. |
| Study on genetic changes in neuroblastoma Posted: 10 Dec 2021 07:31 AM PST 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. |
| AI models microprocessor performance in real-time Posted: 10 Dec 2021 07:31 AM PST 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. |
| Finding the recipe for a larger, greener global rice bowl Posted: 09 Dec 2021 05:17 PM PST 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.' |
| Key step toward personalized medicine: Modeling biological systems Posted: 09 Dec 2021 12:32 PM PST 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. |
| Community of ethical hackers needed to prevent AI's looming 'crisis of trust' Posted: 09 Dec 2021 11:25 AM PST 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. |
| Late-onset retinal degeneration mechanism and potential Rx Posted: 09 Dec 2021 10:39 AM PST A study has discovered how late-onset retinal degeneration can develop and a surprising potential therapeutic -- metformin. |
| Study shows critical need to reduce use of road salt in winter, suggests best practices Posted: 09 Dec 2021 09:45 AM PST 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. |
