Published Can children map read at the age of four?
(via sciencedaily.com) Original source Researchers have found that children start to develop the basic skills that underlie map reading from the age of just four! The study involved 175 two to five-year-olds. It reveals that four-year-olds become able to use a scale model to find things in the real world.
Published Anthropogenic climate change poses systemic risk to coffee cultivation
(via sciencedaily.com) Coffee is important to the economies of coffee producing regions. A new study suggests that climate change may significantly affect land where coffee is cultivated.
Published Unprecedented increase in ocean plastic since 2005 revealed by four decades of global analysis
(via sciencedaily.com) A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
Published Smoke particles from wildfires can erode the ozone layer
(via sciencedaily.com) A new study finds that smoke particles in the stratosphere can trigger chemical reactions that erode the ozone layer -- and that smoke particles from Australian wildfires widened the ozone hole by 10 percent in 2020.
Published Grassroots data vital for reducing deadly bird-window strikes
(via sciencedaily.com) Much of the progress made in understanding the scope of bird deaths from building and window collisions has come as the result of citizen science, according to a newly published study. But the study also concludes that such grassroots efforts need more buy-in from government and industry, and better funding so they can keep a foot on the gas in their efforts to reduce bird-window collisions.
Published Pioneering study shows flood risks can still be considerably reduced if all global promises to cut carbon emissions are kept
(via sciencedaily.com) Annual damage caused by flooding in the UK could increase by more than a fifth over the next century due to climate change unless all international pledges to reduce carbon emissions are met, according to new research.
Published Study into global daily air pollution shows almost nowhere on Earth is safe
(via sciencedaily.com) Original source In a new study of daily ambient fine particulate matter (PM2.5) across the globe, a new study has found that only 0.18% of the global land area and 0.001% of the global population are exposed to levels of PM2.5 -- the world's leading environmental health risk factor -- below levels of safety recommended by Word Health Organization (WHO). Importantly while daily levels have reduced in Europe and North America in the two decades to 2019, levels have increased Southern Asia, Australia, New Zealand, Latin America and the Caribbean, with more than 70% of days globally seeing levels above what is safe.
Published Drones detect moss beds and changes to Antarctica climate
(via sciencedaily.com) Researchers are using drones with highly advanced sensors and AI to map large areas and to study changes to Antarctica's climate.
Published Sea level rise poses particular risk for Asian megacities
(via sciencedaily.com) Original source Sea level rise this century may disproportionately affect certain Asian megacities, according to new research that looks at the effects of natural sea level fluctuations in addition to climate change. The study identified several Asian megacities that may face especially significant risks by 2100, including Chennai, Kolkata, Yangon, Bangkok, Ho Chi Minh City, and Manila.
Published Ocean surface tipping point could accelerate climate change
(via sciencedaily.com) Original source A study has found that intense global warming could shut down the ocean's ability to soak up carbon dioxide, leading to accelerated global warming as the greenhouse gas accumulates in the atmosphere. The decline happens because of a surface layer of low-alkalinity water that emerges during extreme warming that hinders the ability of the oceans to absorb CO2. The study is based on a climate simulation configured to a worst-case emissions scenario that the researchers say must be avoided at all costs.
Published Fighting friction to protect machinery
(via sciencedaily.com) Moving parts in mechanical come into regular contact, leading to wear and tear. Now, researchers have developed a contact control system, driven by artificial intelligence, to greatly reduce contact between damaged parts.
Published Robot provides unprecedented views below Antarctic ice shelf
(via sciencedaily.com) With the help of an underwater robot, known as Icefin, a U.S.- New Zealand research team has obtained an unprecedented look inside a crevasse at Kamb Ice Stream -- revealing more than a century of geological processes beneath the Antarctic ice.
Published Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond
(via sciencedaily.com) Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
Published Tiny new climbing robot was inspired by geckos and inchworms
(via sciencedaily.com) A tiny robot that could one day help doctors perform surgery was inspired by the incredible gripping ability of geckos and the efficient locomotion of inchworms.
Published Reaching like an octopus: A biology-inspired model opens the door to soft robot control
(via sciencedaily.com) Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.
Published This new sensor can detect mercury ions with just a tap
(via sciencedaily.com) Although many measures are in place to prevent contamination, pollutants, such as mercury and lead, can still end up in the environment. Sensing them often requires complicated processes, but what if you could detect them with the tap of a fingertip? Researchers have now developed a self-powered nanosensor that can discover small amounts of mercury ions and immediately report the result.
Published Robot helps students with learning disabilities stay focused
(via sciencedaily.com) Engineering researchers are successfully using a robot to help keep children with learning disabilities focused on their work.
Published Researchers develop new, automated, powerful diagnostic tool for drug detection
(via sciencedaily.com) Biomedical engineers present a robust new method for accurately measuring and identifying eight antidepressants most commonly prescribed to women.
Published Compact, non-mechanical 3D lidar system could make autonomous driving safer
(via sciencedaily.com) A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.
Published Bite this! Mosquito feeding chamber uses fake skin, real blood
(via sciencedaily.com) Bioengineers and experts in tropical medicine have invented a new way of studying mosquito feeding behavior using technology instead of live volunteers. Their open-source design combines automated cameras, artificial intelligence and blood-infused, 3D-printed 'synthetic skin.'
