Published The numbers don't lie: Australia is failing at maths and we need to find a new formula to arrest the decline
(via sciencedaily.com) Australia has suffered a significant drop in teenage maths proficiency in the past 20 years -- sliding from 11th in the OECD rankings to 29th place out of 38 countries, prompting widespread debate over potential curriculum changes. One researcher says hand gestures could stop the slide.
Published Video games can help boost children's intelligence
(via sciencedaily.com) Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect.
Published Landslides can have a major impact on glacier melt and movement
(via sciencedaily.com) Using satellite imagery to study the effects of a 2019 landslide on the Amalia Glacier in Patagonia, a research team found the landslide helped stabilize the glacier and caused it to grow by about 1,000 meters over the last three years.
Published Scientific advance leads to a new tool in the fight against hackers
(via sciencedaily.com) A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.
Published Flood risk for Iowa farmland
(via sciencedaily.com) Researchers have created a detailed set of maps examining the flood risk for all farmland in Iowa. The maps show 450,000 acres of crops in areas with a 50% chance of flooding, and losses from flooding averaging $230 million annually.
Published Drenching rains to pose greater threat to fire-damaged areas in West
(via sciencedaily.com) The western United States this century is facing a greatly heightened risk of heavy rains inundating areas recently scarred by wildfires, new research warns. Such events can cause significant destruction, including debris flows, mudslides, and flash floods, because the denuded landscape cannot easily contain the drenching moisture.
Published Single-photon source paves the way for practical quantum encryption
(via sciencedaily.com) Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
Published Active video games provide alternative workout
(via sciencedaily.com) Working out isn't known for being fun. But new active video and virtual reality games may help change that. Exergaming, or active video gaming, may be the perfect introduction to helping people be more active, according to new research.
Published Computer games in the classroom: Educational success depends on the teacher
(via sciencedaily.com) Future teachers see educational potential in computer games, study shows. Teacher training should therefore address their potential in the classroom.
Published Overlooked channels influence water flow and flooding along Gulf Coast
(via sciencedaily.com) An unnoticed network of channels is cutting across the coastal plain landscape along the Gulf Coast and influencing how water flows, according to new research that could help predict flooding from major storms in the future.
Published California's push for computer science education examined
(via sciencedaily.com) Despite California's computer science education policies, gender, racial and ethnic disparities persist among the high schools that offer these courses, the students enrolled in them and the faculty who teach them.
Published US flood damage risk is underestimated
(via sciencedaily.com) Researchers found a high probability of flood damage -- including monetary damage, human injury and loss of life -- for more than a million square miles of land across the United States across a 14-year period.
Published U.S. coastline to see up to a foot of sea level rise by 2050
(via sciencedaily.com) The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That's according to a NOAA-led report updating sea level rise decision-support information for the U.S. released in partnership with half a dozen other U.S.federal agencies.
Published Spatial training with blocks and puzzles could unlock the UK's mathematical potential
(via sciencedaily.com) A sustained focus on spatial reasoning training could help children learn science, technology, engineering and mathematics.
Published January 2020 Puerto Rico earthquake provides valuable data for ground failure models
(via sciencedaily.com) Field surveys conducted in the days after the 7 January 2020 Puerto Rico earthquake documented more than 300 landslides and severe liquefaction in southern coastal regions, according to a new study.
Published Words are needed to think about numbers, study suggests
(via sciencedaily.com) Researchers have found a new relationship between counting ability of Tsimane' individuals and their ability to perform matching tasks that involve numbers up to about 25. The results suggest that in order to think about exact numbers, people need to have a word for that number.
Published Researchers use tiny magnetic swirls to generate true random numbers
(via sciencedaily.com) Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing.
Published The power of chaos: A robust and low-cost cryptosystem for the post-quantum era
(via sciencedaily.com) Scientists develop a chaos-based stream cipher that can withstand attacks from large-scale quantum computers.
Published Pioneering research forecasts climate change set to send costs of flooding soaring
(via sciencedaily.com) Climate change could result in the financial toll of flooding rising by more than a quarter in the United States by 2050 -- and disadvantaged communities will bear the biggest brunt, according to new research.
Published New study improves understanding of Southern California’s intense winter rains
(via sciencedaily.com) New research looks to improve prediction of brief but intense rainstorms that can cause devastating flash floods and landslides. Intense rain associated with narrow cold-frontal rainbands may last only a few minutes at a particular location, yet the rain can cause catastrophic flash flooding, debris flows and landslides, and can occur along with tornadoes and severe thunderstorms.
