Published Greenhouses cover more and more of Earth's surface



Greenhouse cultivation is booming globally, especially in the Global South -- and across one country in particular. This is revealed in a new study that deploys detailed satellite imagery and AI to map greenhouses across the planet. According to the researchers, the development is a source of both promise and concern.
Published Martian meteorites deliver a trove of information on Red Planet's structure



Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists have analyzed. These results are important for understanding not only how Mars formed and evolved, but also for providing precise data that can inform recent NASA missions like Insight and Perseverance and the Mars Sample Return.
Published Fjords are effective carbon traps regardless of oxygen levels



The fjords on Sweden's west coast act as effective carbon traps regardless of whether the bottom water is oxygen-rich or not.
Published Glimpses of a volcanic world: New telescope images of Jupiter's moon Io rival those from spacecraft



Combining a new imaging instrument with the powerful adaptive optics capabilities of the Large Binocular Telescope, astronomers have captured a volcanic event on Jupiter's moon Io at a resolution never before achieved with Earth-based observations.
Published Medium and mighty: Intermediate-mass black holes can survive in globular clusters



New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed stars. The first ever star-by-star massive cluster-formation simulations revealed that sufficiently dense molecular clouds, the 'birthing nests' of star clusters, can give birth to very massive stars that evolve into intermediate-mass black holes.
Published People are altering decomposition rates in waterways



Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.
Published Historic iceberg surges offer insights on modern climate change



A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.
Published NASA's James Webb Space Telescope finds most distant known galaxy



Over the last two years, scientists have used NASA's James Webb Space Telescope to explore what astronomers refer to as Cosmic Dawn -- the period in the first few hundred million years after the big bang where the first galaxies were born.
Published Local bright spot among melting glaciers: 2000 km of Antarctic ice-covered coastline has been stable for 85 years



A whaler's forgotten aerial photos from 1937 have given researchers the most detailed picture of the ice evolution in East Antarctica to date. The results show that the ice has remained stable and even grown slightly over almost a century, though scientists observe early signs of weakening. The research offers new insights that enhance predictions of ice changes and sea level rise.
Published Indian Ocean surface temperature could help anticipate dengue outbreaks



Although dengue outbreaks cannot be prevented, it is possible to anticipate them. Scientists have recently identified a global climate indicator that may help improve predictions about the magnitude of dengue outbreaks several months in advance. This indicator, which can be used for any world region, is based on temperature fluctuations at the surface of the Indian Ocean. Obtaining reliable long-term predictions could facilitate efforts to tackle this infection, which has been on the rise for several decades and threatens half of the world's population.
Published A drying Salton Sea pollutes neighboring communities



Dust particles from the Salton Sea's exposed lakebed increased air pollution in local communities, found a new study. The pollution coincides with reduced flows into the lake and diversions to San Diego.
Published Abandoned farmlands could play a role in fighting climate change: A new study shows exactly where they are



The team used machine learning to map nearly 30 million acres of United States cropland abandoned since the 1980s, creating a tool that could guide decisions about how to balance production of energy and food.
Published Moon orbiting 'dinky' asteroid is actually two tiny moons stuck together



The moon orbiting the asteroid Dinkinesh is actually two tiny moons stuck together. Collectively called 'Selam,' the two moonlets bring new insight into the complex processes behind planetary formation and evolution.
Published The case of the missing black holes



Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniature black holes than most models suggest, though observations to confirm this should soon be possible. The specific kind of black hole in question could be a contender for dark matter.
Published Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose



Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.
Published New technique offers more precise maps of the Moon's surface



A new study may help redefine how scientists map the surface of the Moon, making the process more streamlined and precise than ever before.
Published Health risk from global warming predictor of city climate action during COVID-19, study finds



City officials were more likely to maintain climate action during the pandemic in places with more climate-related health issues affecting residents.
Published Improved refrigeration could save nearly half of the 1.3 billion tons of food wasted each year globally



A new study concludes that nearly half of the food waste, about 620 million metric tons, could be eliminated by fully refrigerated food supply chains worldwide. At the same time, fully refrigerated supply chains, or 'cold chains,' could cut food waste-related emissions of climate-warming greenhouse gases by 41% globally, according to a new study.
Published Mystery of 'slow' solar wind unveiled by Solar Orbiter mission



Scientists have come a step closer to identifying the mysterious origins of the 'slow' solar wind, using data collected during the Solar Orbiter spacecraft's first close journey to the Sun.
Published Simple food swaps could cut greenhouse gas emissions from household groceries by a quarter



Switching food and drink purchases to very similar but more environmentally friendly alternatives could reduce the greenhouse gas emissions from household groceries by more than a quarter (26%), according to a new study.
