A study using computer simulations suggests Neanderthals could have migrated rapidly across Eurasia during warm periods by following river valleys, covering about 2,000 miles in less than 2,000 years, providing new insights into their migration paths despite limited archaeological evidence.
Researchers have developed computer models that improve understanding of everyday events by responding to uncertainty rather than just prediction errors, suggesting the brain may use dual mechanisms for event comprehension. This challenges previous theories that surprises alone drive understanding. Studies also show that identifying event boundaries enhances memory retention, particularly in older adults, and ongoing research aims to develop interventions for age-related memory loss by improving event segmentation skills.
A major winter storm missed New Hampshire after a significant shift in the storm's track just 24-36 hours before its arrival, leading to only light snow in far southern parts of the state. Meteorologists rely on computer models to make forecasts, and the sudden change was due to a southward shift in the storm's track shown by multiple model runs. Despite modern technology improving forecast accuracy, meteorology remains an imperfect science, and the team aims to continue providing the most accurate forecasts for New Hampshire.
Earth's atmosphere can clean itself by creating hydroxide (OH) through a previously unknown mechanism, according to a new study. Hydroxide oxidises many gases released by natural processes and human activity, decomposing them into water-soluble products that can be washed away and removed from the atmosphere. The study found that a strong electric field that exists at the surface between airborne water droplets and the surrounding air can create OH as well. The findings alter understanding of the sources of OH and will affect how researchers build computer models forecasting air pollution.
Brain decline begins during our 30s and 40s, and not at age 25 as previously believed, according to recent research from University Medical Center Utrecht. The researchers discovered that the connections in our brains become increasingly faster until we are between the ages of 30 and 40, after which it slows down. The study provides important information about our central nervous system and can be used to make more realistic computer models of our brain. The data is publicly accessible, allowing researchers from all over the world to use it.
