Published Low-energy process for high-performance solar cells
(via sciencedaily.com) Original source Finding reliable, eco-friendly power sources is crucial as our world grapples with increasing energy needs and the urgent call to combat climate change. Solar energy offers one solution, with scientists devising ever more efficient materials for capturing sunlight.
Published From fossils to fuel: Mozambique's Maniamba Basin's energy potential
(via sciencedaily.com) Original source In the ever-expanding search for energy resources, a new study has emerged from Mozambique's Maniamba Basin. Mozambique's Maniamba Basin could be a big source of natural gas.
Published Millions in costs due to discharge of scrubber water into the Baltic Sea
(via sciencedaily.com) Original source Discharge from ships with so-called scrubbers cause great damage to the Baltic Sea. A new study shows that these emissions caused pollution corresponding to socio-economic costs of more than EUR 680 million between 2014 and 2022. At the same time, the researchers note that the shipping companies' investments in the much-discussed technology, where exhaust gases are 'washed' and discharged into the sea, have already been recouped for most of the ships. This means that the industry is now making billions of euros by running its ships on cheap heavy fuel oil instead of cleaner fuel.
Published Geologists, biologists unearth the atomic fingerprints of cancer
(via sciencedaily.com) Original source Earth scientists have long turned to minute differences in hydrogen atoms to explore the ancient history of our planet. A new study suggests that these same tiny atoms might also lead to new ways to track the growth of cancer.
Published The Clues for Cleaner Water
(via sciencedaily.com) Original source By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.
Published Astronomers observe elusive stellar light surrounding ancient quasars
(via sciencedaily.com) Original source Astronomers observed the elusive starlight surrounding some of the earliest quasars in the universe. The findings may shed light on how the earliest supermassive black holes became so massive despite having a relatively short amount of cosmic time in which to grow.
Published Hubble views a galaxy with a voracious black hole
(via sciencedaily.com) Original source Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).
Published Sister cities can help communities better navigate the climate crisis
(via sciencedaily.com) Original source Anthropologists suggest in a new study that establishing networks of 'sister cities' dedicated to addressing the impact of natural disasters can mitigate the devastation wrought by climate change.
Published Quantifying U.S. health impacts from gas stoves
(via sciencedaily.com) Original source A new study of air pollution in U.S. homes reveals how much gas and propane stoves increase people's exposure to nitrogen dioxide, a pollutant linked to childhood asthma. Even in bedrooms far from kitchens, concentrations frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off.
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published Ice shelves fracture under weight of meltwater lakes
(via sciencedaily.com) Original source Heavy pooling meltwater can fracture ice, potentially leading to ice shelf collapse.
Published 'Gap' in carbon removal: Countries' plans to remove CO2 not enough
(via sciencedaily.com) Original source New research suggests that countries' current plans to remove CO2 from the atmosphere will not be enough to comply with the 1.5 C warming limit set out under the Paris Agreement.
Published Climate change amplifies severity of combined wind-rain extremes over the UK and Ireland
(via sciencedaily.com) Original source Climate change will cause an increase in extreme winter storms combining strong winds and heavy rainfall over the UK and Ireland, new research has shown.
Published New Nevada experiments will improve monitoring of nuclear explosions
(via sciencedaily.com) Original source On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
Published New eco-friendly lubricant additives protect turbine equipment, waterways
(via sciencedaily.com) Original source Scientists have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
Published Oil palm plantations are driving massive downstream impact to watershed
(via sciencedaily.com) Original source The global demand for palm oil -- the most widely consumed vegetable oil on the planet, in everything from instant noodles to lipstick -- is driving worldwide tropical deforestation. While many studies have shown the loss of biodiversity when rainforests are converted to oil palm plantations, researchers have now shown the far-reaching and wide-ranging disturbances to the watersheds in which such plantations occur.
Published Human activity is causing toxic thallium to enter the Baltic sea, according to new study
(via sciencedaily.com) Original source Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
Published Path to easier recycling of solar modules
(via sciencedaily.com) Original source The use of femtosecond lasers to form glass-to-glass welds for solar modules would make the panels easier to recycle, according to a proof-of-concept study.
Published Robots invited to help make wind turbine blades
(via sciencedaily.com) Original source Researchers have successfully leveraged robotic assistance in the manufacture of wind turbine blades, allowing for the elimination of difficult working conditions for humans and the potential to improve the consistency of the product.
Published Wildfires in wet African forests have doubled in recent decades
(via sciencedaily.com) Original source Climate change and human activities like deforestation are causing more fires in central and west Africa's wet, tropical forests, according to the first-ever comprehensive survey there. The fires have long been overlooked.
