Domestic cats originated in North Africa and spread to Europe in the past 2000 years, according to DNA evidence, while in China a different species of cat lived alongside people much earlier
A new tool shows it is possible to turn down the partisan rancor in an X feed—without removing political posts and without the direct cooperation of the platform.
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
Authorities across Indonesia, Thailand and Malaysia worked on Thursday to reach residents trapped in floods that have killed dozens of people across the region in recent days.

Newly discovered fossils prove that a mysterious foot found in Ethiopia belongs to a little-known, recently named ancient human relative who lived alongside the species of the famous Lucy, scientists said Wednesday.
When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed.
Hotter temperatures and a series of droughts in what is now Pakistan and India fragmented one of the world’s major early civilisations, providing a "warning shot" for today
Instagram users may overestimate the extent to which they are addicted to the platform, according to research conducted on 1,204 U.S. adults published in Scientific Reports. The findings suggest that for most social media users, excessive use is driven by habit rather than
Successive major droughts, each lasting longer than 85 years, were likely a key factor in the eventual fall of the Indus Valley Civilization, according to a paper published in Communications Earth & Environment. The findings may help explain why this major ancient
Dogs were the first of any species that people domesticated, and they have been a constant part of human life for millennia. Domesticated species are the plants and animals that have evolved to live alongside humans, providing nearly all of our food and numerous other benefits.
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Human development and climate-driven sea level rise are accelerating global beach erosion and undermining the natural processes that sustain coastal ecosystems. Studies reveal that urban activity on the sand harms biodiversity in every connected zone, magnifying worldwide
Chytrid fungus is a scourge to global amphibian populations, but before it kills some frogs, it can produce symptoms that may help the infected animals find mates and spread the fungus further
University of Queensland researchers visualized yellow fever virus particles at near-atomic detail, uncovering major structural differences between vaccine and virulent strains. The insights could lead to better vaccines and treatments for yellow fever and related
New research has revealed that marine mammals who live far below the ocean's surface are not immune from the burden of toxic forever chemicals, with whales and dolphins showing unprecedented levels of PFAS contamination.
Researchers have discovered a low-energy way to recycle Teflon® by using mechanical motion and sodium metal. The process turns the notoriously durable plastic into sodium fluoride that can be reused directly in chemical manufacturing. This creates a potential circular economy
A photosynthetic bacterium shows a surprising ability to absorb persistent PFAS chemicals, offering a glimpse into biological tools that might one day tackle toxic contamination. Researchers are now exploring genetic and synthetic biology approaches to enhance these early signs
Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection of an exceptional gamma-ray flare from this object.
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing the reliability with which all thermal machines
The study reveals that widely used heart-attack risk calculators fail to flag nearly half of those who will soon experience a cardiac event. Even the newer PREVENT model misclassifies many patients as low-risk. Since most people develop symptoms only within 48 hours of their
The material used to build the Temple of Venus in Naples has remarkably endured even as Earth's surface around it sank from volcanic activity, and researchers were curious to know how.
Spermine, a small but powerful molecule in the body, helps neutralize harmful protein accumulations linked to Alzheimer’s and Parkinson’s. It encourages these misfolded proteins to gather into manageable clumps that cells can more efficiently dispose of through autophagy.
Texas A&M researchers found a way to make stem cells produce double the normal number of mitochondria using nanoflower particles. These energized stem cells then transfer their surplus “power packs” to weakened cells, reviving their energy production and resilience. The method
Despite their wild variety of sizes, niches, and shapes, sharks scale geometrically, pointing to possible fundamental constraints on evolution The post Sharks Show How Animals Scale Like Geometric Objects appeared first on Nautilus .
A 20-year project in Bangladesh reveals that lowering arsenic levels in drinking water can slash death rates from major chronic diseases. Participants who switched to safer wells had the same risk levels as people who were never heavily exposed. The researchers tracked
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study published in Nature Communications by Marcia group, has captured, for the first
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must advance down the gene in perfect sync with other
Climate change conditions turn plastics into more mobile, persistent, and hazardous pollutants. This is done by speeding up plastic breakdown into microplastics—microscopic fragments of plastic—spreading them considerable distances, and increasing exposure and impact within the
They say an elephant never forgets—and it turns out they can learn to adapt to drones. Once seen as a source of alarm, drones are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, the use of drones in elephant conservation has mostly
A satellite deployed to measure ocean surface heights was up to the challenge when a massive earthquake off the Kamchatka Peninsula triggered a Pacific-wide tsunami in late July.
A bull shark killed a woman swimming off a remote beach in Australia's eastern state of New South Wales Thursday while a man was seriously injured and may have been saved by the "heroic" efforts of a passerby.
The world's top wildlife trade body voted Thursday to effectively ban all international trade in the critically endangered oceanic whitetip shark but rejected a proposal to protect more species of eel.
European Union countries are progressing toward the United Nations Sustainable Development Goals (SDGs), but not at the same pace.

A massive veteran study found a strong connection between untreated sleep apnea and a higher chance of Parkinson’s. CPAP users had much lower odds of developing the condition. Researchers believe that repeated dips in oxygen during sleep may strain neurons over time. The
The cherry harvest wrapped up months ago. But in northern Michigan, some growers are already anticipating the spring resurgence of a tiny raptor that could benefit next season's crop.
As climate change and the resulting extreme weather intensify, interest in weather modification is growing around the world. In Japan, under Goal 8 of the Moonshot Research and Development Program led by the Cabinet Office / JST (Japan Science and Technology Agency), a research
