Published Scientists create high-efficiency sustainable solar cells for IoT devices with AI-powered energy management



Researchers have created environmentally-friendly, high-efficiency photovoltaic cells that harness ambient light to power internet of Things (IoT) devices.
Published Shift to 'flash droughts' as climate warms



'Flash droughts' have become more frequent due to human-caused climate change and this trend is predicted to accelerate in a warmer future, according to new research.
Published Predictive power of climate models may be masked by volcanoes



Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study.
Published Research in Japan shows the way toward tactile and proximity sensing in large soft robots



To make human-robot interactions safer and more fruitful, robots should be capable of sensing their environment. In a recent study, researchers developed a novel robotic link with tactile and proximity sensing capabilities. Additionally, they created a simulation and learning framework that can be employed to train the robotic link to sense its environment. Their findings will pave the way to a future where humans and robots can operate harmoniously in close proximity.
Published Toward a safer 'artificial muscle' material



Whether wriggling your toes or lifting groceries, muscles in your body smoothly expand and contract. Some polymers can do the same thing -- acting like artificial muscles -- but only when stimulated by dangerously high voltages. Now, researchers report a series of thin, elastic films that respond to substantially lower electrical charges. The materials represent a step toward artificial muscles that could someday operate safely in medical devices.
Published Critical observations of sinking coasts



Using satellite-obtained data from 2007-21, researchers mapped the entire East Coast to demonstrate how the inclusion of land subsidence reveals many areas to be more vulnerable to floods and erosion than previously thought.
Published World's biggest cumulative logjam, newly mapped in the Arctic, stores 3.4 million tons of carbon



Throughout the Arctic, fallen trees make their way from forests to the ocean by way of rivers. Those logs can stack up as the river twists and turns, resulting in long-term carbon storage. A new study has mapped the largest known woody deposit, covering 51 square kilometers (20 square miles) of the Mackenzie River Delta in Nunavut, Canada, and calculated that the logs store about 3.4 million tons (about 3.1 million metric tons) of carbon.
Published As rising temperatures affect Alaskan rivers, effects ripple through Indigenous communities



Six decades of river gage data gathered from nine rivers in Alaska highlight the cumulative and consequential impacts of climate change for local communities and ecosystems in the Arctic.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball



Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published The 2022 Durban floods were the most catastrophic yet recorded in KwaZulu-Natal



Research shows flooding events in the province have doubled in the last century.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards



Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published Table tennis brain teaser: Playing against robots makes our brains work harder



Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published Spike in major league home runs tied to climate change



A new study identifies the influence of climate change in the greater number of home runs in major league baseball in recent years. The researchers found that more than 500 home runs since 2010 can be attributed to warmer, thinner air caused by global warming, and that rising temperatures could account for 10% or more of home runs by 2100 if greenhouse gas emissions continue unabated. The researchers examined how the average number of home runs per year could rise for each major league ballpark with every 1-degree Celsius increase in the global average temperature.
Published Moving towards 3 degrees of warming -- the phasing out of coal is too slow



The use of coal power is not decreasing fast enough. The Paris Agreement's target of a maximum of 2 degrees of warming appear to be missed, and the world is moving towards a temperature increase of 2.5 -- 3 degrees. At the same time it is feasible to avoid higher warming.
Published Researchers correlate Arctic warming to extreme winter weather in midlatitude and its future



A warmer Arctic has been linked to extreme winter weather in the midlatitude regions. But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data and climate models, that while the 'Warm Arctic-Cold Continent' pattern will continue as the climate continues to warm, Arctic warming will become a less reliable predictor of extreme winter weather in the future.
Published Ice sheets can collapse faster than previously thought possible



Ice sheets can retreat up to 600 meters a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured. An international team of researchers used high-resolution imagery of the seafloor to reveal just how quickly a former ice sheet that extended from Norway retreated at the end of the last Ice Age, about 20,000 years ago.
Published The unexpected contribution of medieval monks to volcanology



By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers drew on readings of 12th and 13th century European and Middle Eastern chronicles, along with ice core and tree ring data, to accurately date some of the biggest volcanic eruptions the world has ever seen. Their results uncover new information about one of the most volcanically active periods in Earth's history, which some think helped to trigger the Little Ice Age, a long interval of cooling that saw the advance of European glaciers.
Published Civil engineers use public satellite images to study why the Jagersfontein dam failed



Study by civil engineers finds that the history of the Jagersfontein dam deviates from best engineering practice.
Published A cold-specialized icefish species underwent major genetic changes as it migrated to temperate waters



Biologists have explored the genetic mechanisms underlying the transition from freezing Antarctic waters to more temperature waters by Antarctic Notothenioid fish.
Published Robots predict human intention for faster builds



Humans have a way of understandings others' goals, desires and beliefs, a crucial skill that allows us to anticipate people's actions. Taking bread out of the toaster? You'll need a plate. Sweeping up leaves? I'll grab the green trash can. This skill, often referred to as 'theory of mind,' comes easily to us as humans, but is still challenging for robots. But, if robots are to become truly collaborative helpers in manufacturing and in everyday life, they need to learn the same abilities. Computer science researchers aim to teach robots how to predict human preferences in assembly tasks, so they can one day help out on everything from building a satellite to setting a table.
