Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published Climate change to push species over abrupt tipping points
(via sciencedaily.com) Original source Climate change is likely to abruptly push species over tipping points as their geographic ranges reach unforeseen temperatures, finds a new study.
Published Automated window shades show potential for significant energy savings
(via sciencedaily.com) Original source Automated insulating window shades can cut energy consumption by approximately one-quarter and may recoup the cost of installation within three to five years, according to a landmark study. The study showcases a promising path for sustainability and energy efficiency in architectural design.
Published Assessing emotions in wild animals
(via sciencedaily.com) Original source A new study examines indicators of mental wellbeing in wild animals to improve conservation efforts.
Published Extremely hot days are warming twice as fast as average summer days in North-West Europe
(via sciencedaily.com) Original source New study analyzed data on near-surface air temperatures recorded for North-West Europe over the past 60 years. The findings show that the maximum temperature of the hottest days is increasing at twice the rate of the maximum temperature of average summer days. The results highlight the need for urgent action by policy makers to adapt essential infrastructure to the impacts of climate change.
Published Radio signal reveals supernova origin
(via sciencedaily.com) Original source Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.
Published NASA's Spitzer, TESS find potentially volcano-covered Earth-size world
(via sciencedaily.com) Original source Astronomers have discovered an Earth-size exoplanet, or world beyond our solar system, that may be carpeted with volcanoes. Called LP 791-18 d, the planet could undergo volcanic outbursts as often as Jupiter's moon Io, the most volcanically active body in our solar system.
Published The number of the world's farms to halve by 2100
(via sciencedaily.com) Original source New research shows the number of farms globally will shrink from 616 million in 2020 to 272 million in 2100, posing significant risks to the world's food systems.
Published Chemical exposure may raise your risk for Parkinson's
(via sciencedaily.com) Original source Two years of heavy exposure to TCE, a liquid chemical that lingers in the air, water and soil, may increase the risk of Parkinson's disease by 70%.
Published African smoke over the Amazon
(via sciencedaily.com) Original source Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.
Published About 13,000 years ago, the water outflow from the Mediterranean to the Atlantic Ocean was twice that of today’s
(via sciencedaily.com) Original source About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across the Mediterranean basin, which had a major impact on terrestrial and marine ecosystems. But what do we know about the impact of this climate change on water circulation in the Mediterranean?
Published 'Warm Ice Age' changed climate cycles
(via sciencedaily.com) Original source Approximately 700,000 years ago, a 'warm ice age' permanently changed the climate cycles on Earth. During this exceptionally warm and moist period, the polar glaciers greatly expanded. A research team identified this seemingly paradoxical connection. The shift in the Earth's climate represents a critical step in our planet's later climate development.
Published South Africa's desert-like interior may have been more inviting to our human ancestors
(via sciencedaily.com) Original source Lining the Cape of South Africa and its southern coast are long chains of caves that nearly 200,000 years ago were surrounded by a lush landscape and plentiful food.
Published Out of this world control on Ice Age cycles
(via sciencedaily.com) Original source A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show that the glacial cycle was driven primarily by astronomical forces in quite a different way than it works in the modern age. These results will help us to better understand the past, present, and future of ice sheets and the Earth's climate.
Published Porous crystals made from plant extracts purify water from pharmaceutical pollutants
(via sciencedaily.com) Original source Researchers have developed porous crystals made from pomegranate extract to capture and degrade pharmaceutical molecules found in local municipal wastewater.
Published With formic acid towards CO2 neutrality
(via sciencedaily.com) Original source Researchers develop a new method for the sustainable use of carbon dioxide.
Published Astronomers observe the first radiation belt seen outside of our solar system
(via sciencedaily.com) Original source Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to radio images of Jupiter's radiation belts.
Published New study puts a definitive age on Saturn's rings -- they're really young
(via sciencedaily.com) Original source Physicists measured the flux of interplanetary dust around Saturn. The researchers concluded that the planet's rings formed less than 400 million years ago, making them much younger than Saturn itself.
Published Astronomers reveal the largest cosmic explosion ever seen
(via sciencedaily.com) Original source Astronomers have uncovered the largest cosmic explosion ever witnessed. The explosion is more than ten times brighter than any known supernova and three times brighter than the brightest tidal disruption event, where a star falls into a supermassive black hole.
