Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted “dual origins” theory. The newly identified ancestry appears linked to the ancient Emishi people of northeastern Japan. Researchers also uncovered inherited Neanderthal and Denisovan DNA connected to conditions...

Combined Short-Term Effects of Air Pollutants Linked to 146,500 Premature Deaths per Year in Europe
Fine particles (PM₂.₅) were associated with around 79,000 preventable deaths, followed by nitrogen dioxide (NO₂), ozone (O₃) and coarser particles (PM₂.₅-₁₀, particles with a diameter between 2.5 and 10 micrometres).
Protected Area Managers Across Europe are Adapting to Climate Change
New research shows how climate change is reshaping protected area management, though more funding and scientific knowledge are needed to facilitate the process.
Study Finds Wetter Storms Mean Drier Conditions Over Time
A Dartmouth study shows that annual rainfall in much of the world has consolidated over the past four decades into heavier storms with longer dry periods in between.
A rare cancer-fighting plant compound has been decoded
Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a mystery that had puzzled researchers for years. Because mitraphylline appears only in tiny amounts...
UC Irvine Team Identifies Where Renewable Hydrogen Delivers the Greatest Social Benefit
Renewable electrolytic hydrogen produced by using electricity drawn from wind and solar sources delivers its greatest societal value when applied to steelmaking, transoceanic shipping and long-haul heavy-duty trucking, according to University of California, Irvine researchers.
Climate Change: How Oxygen Deficiency Changes Metabolic Processes in the Ocean
A new study reveals how sulfur compounds are metabolized under oxygen-deficient conditions – and which microorganisms are responsible.
For Most US Drivers, EVs Offer Emissions Benefits and Cost Savings
Despite regional variability in climate, electricity sources, congestion, and the wide variation in individual driving patterns, electric vehicles generate less greenhouse gas emissions and do not cost more than comparable gas-powered vehicles for drivers and vehicle fleet owners in most parts of the United States, according to a new study...
As the Planet Warms, Why Is the Upper Atmosphere Cooling?
While our emissions are trapping heat near the surface of the Earth, they are having the opposite effect in the upper atmosphere.
Lab-Grown Algae Removes Microplastics From Water
Professor Susie Dai has engineered special algae to remove and reuse harmful microplastics from wastewater.
