    Romanian fossils show hominins in Europe 500,000 years earlier than thought

    Research led by the Department of Sociology & Anthropology at Ohio University has found evidence of hominin activity at a Romanian fossil site dating to at least 1.95 million years ago. This discovery pushes back the known date of European hominins by half a million years and establishes Grăunceanu as the oldest confirmed European evidence of hominin activity.

    New water purification technology helps turn seawater into drinking water without tons of chemicals

    Water desalination plants could replace expensive chemicals with new carbon cloth electrodes that remove boron from seawater, an important step of turning seawater into safe drinking water.

    Deep beneath California's Sierra Nevada, Earth's lithosphere may be peeling away

    The processes that form continental crust from the denser basaltic rocks of the upper mantle may make the lower lithosphere denser than the underlying mantle. One theory holds that the lower lithosphere splits away and sinks into the mantle in a process called foundering. Conclusive evidence of foundering, however, has been hard to come by.

    Colorado releases 15 wolves from Canada in second round of historic reintroduction

    Colorado wildlife officials released 15 wolves from Canada into the central mountains over the last week as part of the second wave of the state's historic, voter-mandated reintroduction of the native predator.

    US to withdraw from Paris agreement, expand drilling

    President Donald Trump on Monday announced the United States would withdraw from the Paris climate accord for a second time, a defiant rejection of global efforts to combat planetary warming as catastrophic weather events intensify worldwide.

    Religious 'mercy release' of hybrid groupers can have significant ecological impact

    Ecologists from the School of Biological Sciences (SBS) and the Swire Institute of Marine Science (SWIMS) at The University of Hong Kong (HKU) have identified significant ecological risks associated with the release of hybrid groupers into Hong Kong's coastal waters, a practice often linked to religious 'mercy release' rituals.

    Scientists succeed in trapping molecules to perform quantum operations for the first time

    Molecules haven't been used in quantum computing, even though they have the potential to make the ultra-high-speed experimental technology even faster. Their rich internal structures were seen as too complicated, too delicate, too unpredictable to manage, so smaller particles have been used.

    Improved radon gas mapping finds nearly 25% of Americans living in highest risk areas

    Researchers from Harvard T.H. Chan School of Public Health have assembled a national database with millions of multi-day indoor radon measurements from 2001 to 2021. Findings reveal that nearly 25% of the U.S. population may be exposed to radon concentrations exceeding 148 Bq/m3, a level associated with cancer risks.

    'Troublesome' radio galaxy 32 times the size of Milky Way spotted

    Astronomers have discovered an extraordinary new giant radio galaxy with plasma jets 32 times the size of our Milky Way.

    Largest study of its kind proves 'bird brain' is a misnomer

    It's difficult to know what birds "think" when they fly, but scientists in Australia and Canada are getting some remarkable new insights by looking inside birds' heads.

    M87* observations catch the black hole's turbulent accretion flow

    Using observations from 2017 and 2018, the Event Horizon Telescope (EHT) Collaboration has advanced our understanding of the supermassive black hole at the center of Messier 87 (M87*). This study marks a significant step toward multi-year analysis at horizon scales, in order to investigate the black hole's turbulent accretion flow. It utilizes a vastly improved set of simulations that is a factor of three larger than previous ones. The results include major contributions from the MPIfR in Bonn, Germany.

    Student project discovers superconductor with hallmark of unconventional superconductivity

    Researchers from Tokyo Metropolitan University have discovered a new superconducting material. They combined iron, nickel, and zirconium, to create a new transition metal zirconide with different ratios of iron to nickel. The findings are published in the Journal of Alloys and Compounds.

    SMART: One step closer to nuclear fusion with its first plasma

    In a pioneering approach to achieve fusion energy, the SMART device has successfully generated its first tokamak plasma. This step brings the international fusion community closer to achieving sustainable, clean, and virtually limitless energy through controlled fusion reactions.

    Researchers report the first-ever total synthesis of a promising mushroom-derived compound

    Natural compounds from plants and animals have long been used in drug development, but mushrooms remain underexplored despite their rich chemical potential. Now, researchers from Japan have successfully developed the first method to synthesize inaoside A, a compound derived from the edible mushroom Laetiporus cremeiporus. This achievement will help better understand more of its bioactive properties and pave the way for similar mushroom-derived compounds in pharmaceuticals and functional foods.

    Mitochondria may be a promising therapeutic target for inflammatory diseases

    Scientists in the laboratory of Navdeep Chandel, Ph.D., the David W. Cugell, MD, Professor of Medicine in the Division of Pulmonary and Critical Care, have discovered how mitochondria influence the body's immune response through modulating specific cell signaling pathways, according to a study published in Science Advances.

    Chinese 'artificial sun' sets a record towards fusion power generation

    The Experimental Advanced Superconducting Tokamak (EAST), commonly known as China's "artificial sun," has achieved a remarkable scientific milestone by maintaining steady-state high-confinement plasma operation for an impressive 1,066 seconds. This accomplishment, reached on Monday, sets a new world record and marks a significant breakthrough in the pursuit of fusion power generation.

    Cosmological data suggest the universe has become 'messier and more complicated'

    Across cosmic history, powerful forces have acted on matter, reshaping the universe into an increasingly complex web of structures. Now, new research led by Joshua Kim and Mathew Madhavacheril at the University of Pennsylvania and their collaborators at Lawrence Berkeley National Laboratory suggests our universe has become "messier and more complicated" over the roughly 13.8 billion years it's been around, or rather, the distribution of matter over the years is less "clumpy" than it should be expected.

    Machine learning and 3D printing yield steel-strong, foam-light materials

    Researchers at the University of Toronto's Faculty of Applied Science & Engineering have used machine learning to design nano-architected materials that have the strength of carbon steel but the lightness of Styrofoam.

    After millennia as CO₂ sink, more than one-third of Arctic-boreal region is now a source

    After millennia as a carbon deep-freezer for the planet, regional hotspots and increasingly frequent wildfires in the northern latitudes have nearly canceled out that critical storage capacity in the permafrost region, according to a study published in Nature Climate Change.

    Spotted hyena found in Egypt for the first time in 5,000 years

    A spotted hyena (Crocuta crocuta) has been found in South Eastern Egypt, the first recorded instance of the creature in this region for thousands of years.
