New tool maps public land with potential for hundreds of thousands of affordable homes in British Columbia‎

A new research tool is highlighting publicly owned land that may have potential for affordable housing development in B.C., with early analysis revealing more than 50,000 parcels of publicly owned land in B.C. and up to 273,000 potential housing units on vacant and underused land in Metro Vancouver alone. The B.C. Public Lands Map is the first tool of its kind in Canada, combining federal, provincial and municipal data to identify prime parcels of public land—from empty plots to vacant government buildings to surface parking lots—suitable for affordable housing development.

LSST begins full operations with key contributions from Japanese researchers and engineers‎

NSF–DOE Vera C. Rubin Observatory has officially begun full operations for the Legacy Survey of Space and Time (LSST), one of the world's largest astronomical imaging surveys. Behind the scenes, Japanese researchers and engineers are drawing on technologies and expertise cultivated through the development and operation of the Subaru Telescope to support the project's software, systems and operations. More than 80 researchers from Japan are already participating in LSST science through access to its data. Looking ahead, the combination of Rubin's wide-area survey and the Subaru Telescope's detailed follow-up observations will help advance our understanding of fundamental mysteries of the universe.

Huge, specially designed heat pump saves a Norwegian agricultural cooperative millions‎

There are some magical limits to how much energy we can get out of a heat pump. This story is about pushing the technical limits. It is about getting more energy out than you put in. And it's about how SINTEF—one of Europe's largest applied research organizations—the renewable energy company Aneo, and the Norwegian agricultural cooperative Felleskjøpet together managed to shift the recovery of process heat from theoretical calculations in researchers' notebooks to becoming an industrial electricity-saving project on a large scale.

Sun-powered sponges may generate 11% of tropical coral reef productivity‎

In marine environments, sponges tend to eat other organisms to get their nutrients. But a study published in Functional Ecology by researchers at the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics (IBED), demonstrates how sponges may also use photosynthesis, just like plants. This phenomenon can help with productivity—the amount of energy and food produced—in tropical coral reefs, and perhaps in other ecosystems where sponges are also common.

How extreme weather impacts white stork survival in Bulgaria‎

A comprehensive 15-year study published in Biodiversity Data Journal details the growing threat of extreme weather to white storks (Ciconia ciconia) in Bulgaria. The research, which is part of the topical collection "Restoration of species of conservation importance," analyzes the admissions and treatment outcomes of injured storks at the Wildlife Rescue and Breeding Center (WRBC) of the Green Balkans NGO between 2010 and 2025.

Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals‎

New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna consistently from Alaska to South America.

New star activity catalog could sharpen hunt for habitable worlds‎

Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star's habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75% of the planet's surface, life is abundant. But what about the exoplanet's star, specifically its activity and rotation? How could this influence how exoplanets are identified for current and future missions?

Hidden for decades, hospital superbug built resistance in waves, peaking in the mid‑2000s‎

Decades-old hospital samples have helped University of East Anglia (UEA) researchers uncover how a deadly antibiotic-resistant "superbug" quietly tightened its grip across the globe. It lurked in hospital corridors for decades, largely unnoticed by the wider public.

Over the past 15 years, Brazil has seen a more than 200% increase in non-native mollusk species‎

A study published in the journal Biological Invasions indicates that Brazil currently has at least 82 non-native mollusk species, in addition to 13 whose origin cannot be determined. This represents a 215% increase compared with 2011, when 26 species were reported.

Cosmic dust could play key role in cracking long-standing mystery of solar corona heating‎

A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through the solar corona, the outer atmosphere of the sun. The discovery potentially rewrites how scientists understand why the corona is millions of degrees hotter than the surface of the sun itself.
