    OpenAI says its AI model solved a famous 80-year-old maths problem that puzzled experts for decades, marking a major breakthrough in AI-powered research and reasoning.The artificial intelligence boom is real. Sectors like healthcare, IT, education and many others are rapidly moving towards AI adoption. Now mathematicians have also acknowledged how AI is proving its mettle. OpenAI announced on Wednesday that one of its reasoning models has solved a famous maths problem that humans could not solve in 80 years. Notably, the maths problem, known as the ‘planet unit distance’, was initially proposed in 1946 by legendary mathematician Paul Erdős. Since...

    As scientists study Earth's oceans, they come across some intriguing mysteries. Among them are some of the strangest deep-sea discoveries, including a "golden orb" measuring about 4 inches in diameter in the Gulf of Alaska in 2023. Referred to as a "yellow hat" by one of the videographers at the time, researchers were stumped about what it could be; coral, an egg casing, or a dead sponge attachment were some of the initial guesses. Since then, they've been able to determine that it's dead cell remains from a huge deep-sea anemone. The golden specimen was found about 2 miles beneath...

    Mexican Coke tastes different than American Coke; after all, it’s sweetened using cane sugar instead of high-fructose corn syrup. That, at least, was the conventional wisdom until 2011, when a paper published in the journal Obesity found that Mexican Coke contained no cane sugar. Instead, the authors found plenty of glucose and fructose, which are the main ingredients in high-fructose corn syrup.

    A new study found that when you lose your virginity may impact how well you age later in life, including outcomes like frailty and misery in older adulthood. “Our findings suggest that the timing of first sexual intercourse may be connected to aging through multiple psychological, behavioral and disease-related pathways,” first author Kaixian Wang said in a press release. They found that those with genetic signals tied to earlier loss of virginity tended to have less favorable aging-related outcomes, including higher frailty and poorer longevity-related measures. SNIP “Frailty index, miserableness, chronic obstructive pulmonary disease (COPD) and attention-deficit/hyperactivity disorder (ADHD) appeared...
  • How Egypt’s Great Pyramid Survived Thousands of Years of Earthquakes

    The mystery of how Egypt’s pyramids survived thousands of years of earthquakes may partly come down to smart engineering, according to a new study that examined how the Great Pyramid of Giza responds to seismic vibrations. Researchers found that the Pyramid of Khufu has a natural vibration frequency that differs sharply from the surrounding ground, helping reduce the risk of dangerous resonance during earthquakes. The study, led by Mohamed ELGabry and published in Scientific Reports, analyzed ambient seismic noise recorded inside the 4,600-year-old pyramid. Researchers said the findings may explain why the structure has survived centuries of earthquakes with little...
  • Ancient DNA Reveals a Hidden Migration Network Across Peru Before the Inca

    Greek Reporter ^ | May 23, 2026 | Abdul Moeed
    Ancient DNA extracted from human remains in Peru shows that long-distance migration along the Pacific coast began centuries before the Inca Empire expanded into the region. A study published in Nature Communications traces this movement to at least the 13th century, offering new insight into how coastal communities formed and connected long before any imperial force arrived. Jacob L. Bongers, an archaeologist at the University of Sydney and lead author of the study, analyzed genome-wide data from 21 individuals buried in the Chincha Valley of southern Peru. The results show that early inhabitants carried genetic ancestry from populations living about...

    Explanation: This cosmic snapshot covers a field of view over twice as wide as the full Moon within the boundaries of the high-flying constellation Cygnus. Made using astronomical narrowband filters, the image highlights the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas. Embedded in the region's expanse of interstellar clouds, the complex, glowing arcs are sections of shells of material swept up by the wind from Wolf-Rayet star WR 134, the brightest star near image center. Distance estimates put WR 134 about 6,000 light-years away, making this telescopic frame over 100 light-years...

    The Pegasus team from the Aris student space initiative has generated a stable detonation wave with its engine. Robin Wyss / Aris Space ========================================================================= Students in Switzerland have recently tested an experimental rocket engine that is capable of generating 20,000 detonation waves per second, the same propulsion concept explored by NASA and Japanese researchers for future space missions. The so-called rotating detonation rocket engine (RDRE) is powered by propane and liquid oxygen. It was built by the Pegasus team, a student project within the ARIS (Academic Space Initiative Switzerland) at ETH Zurich. The third-year students spent nearly a year developing...

    Credit: CTIO/NOIRLab/DOE/NSF/AURA/J. Pollard Image Processing: D. de Martin & M. Zamani (NSF NOIRLab) =============================================================================== In A Nutshell A 37-member international team produced the most precise direct measurement of the Hubble constant ever recorded, with just 1.1 percent uncertainty. By linking a dozen different cosmic distance measurement methods into a single “Distance Network,” they confirmed the universe is currently expanding at about 73.5 kilometers per second per 3.26 million light-years. That rate conflicts with what the Big Bang’s ancient afterglow predicts by more than seven times the margin of error, a gap that makes a simple measurement mistake increasingly implausible.

    A mutant super pig population has spiraled out of control — thanks to their inherited, rapid reproductive cycles — in the ghost towns of a nuclear fallout zone in Japan, according to reports and researchers. The 2011 Fukushima Daiichi Nuclear Power Plant disaster, spurred by a massive 9.0-magnitude earthquake and tsunami, forced roughly 164,000 people to flee from their homes to escape the radiation zone. Amid the chaos, domestic pigs escaped into abandoned farmland and began interbreeding with indigenous feral boars — creating a mutant pig population with alarming genes, Popular Science reported. Researchers from Fukushima and Hirosaki Universities discovered...

    Explanation: This big beautiful spiral shines in X-ray light. It is about 20 times larger than our Galaxy. It belongs to Abell 2029, a galaxy cluster one billion light-years away. (To see only the galaxies, hover your cursor over the image, or follow this link.) Galaxy clusters are the largest structures in the universe that are supported by gravity. Abell 2029 is formed by thousands of galaxies, surrounded by a huge cloud of hot gas and the equivalent of hundreds of trillions times the mass of the Sun in dark matter. The spiral is made of gas, mostly hydrogen and...

    A UN body of researchers that puts together possible climate scenarios announced last week that one extreme scenario it put forward back in 2011 is no longer plausible. As Roger Pielke Jr. from AEI puts it, the climate apocalypse is no longer around the corner.The climate apocalypse isn’t around the corner after all. That’s the upshot of a recent report from the international panel that supplies official “scenarios” to researchers, governments and banks. It turns out that the most extreme assumptions about the future — the doomsaying predictions embodied in the worst-case scenario known as RCP8.5 — are “implausible.”...The substance...

    Explanation: A dark wolf lies in gum. No, this isn’t a riddle! Today's image features the Dark Wolf Nebula (Sandqvist–Lindroos 17), a spooky dust cloud embedded within the Gum 55 (RCW 113) Nebula in the Scorpius constellation. While dust is a pest to us, it serves a vital role in creating the necessary conditions for stars to be born. The Dark Wolf absorbs the intense ultraviolet and visible light emitted by young stars in Gum 55 and re-emits it at longer, mainly infrared, wavelengths. This prevents the higher energy light from heating up the gas in the region. When a...

    We Could, We Should, We MustOn Insects As a Delivery System, and “Beneficial Bloodsucking.”A few summers ago I gave consideration to moving to Florida or Texas. This was 2021 when it felt like there was a collective madness in my hometown of New York City. If you remember that moment, you remember the destinations where people like me were fleeing. I was looking into places like Florida and Texas. The so-called free states, the escape hatches (not my framing but more of a public consciousness in a particular demographic that I had seemed to become a part of). I compiled...

    ...The discovery was made by Henrik Refsnes Mørtvedt, a first-grade pupil at Fredheim School, during a class trip in the Brandbu area of the Gran municipality, in Norway's Innlandet county. According to NRK, Henrik spotted part of the object protruding from the soil while walking across a field with his classmates...Instead of treating it as a souvenir, they contacted local archaeologists. That decision may have saved an important piece of Norway's early medieval past.Archaeologists identified the object as a single-edged sword, meaning it was sharpened on only one side. This type of blade is often associated with the Merovingian Period...

    Explanation: Is this a painting or a photograph? In this celestial abstract art composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines just above the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that abstract painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in a setting like this one -- a massive,...

    Could this bring species back from egg-stinction? Texas firm Colossal Biosciences, which has dedicated itself to resurrecting lost species, including the dire wolf and woolly mammoth, has hatched live chicks from an artificial egg for the first time — a crucial, “Jurassic Park”-esque step in its mission to bring back the moa and other giant, long-gone avians. The first-of-its-kind artificial egg allows a bird embryo to develop completely outside of a biological shell while scientists oversee every aspect from early embryo to hatching. The team hatched 26 “healthy” chickens, which “will live out their natural lives” at the company’s avian...
