    Ryugu is probably a chip off one of these two other asteroids

    THE WOODLANDS, Texas — The asteroid Ryugu is a chip off the old block. Planetary scientists on the Japanese Hayabusa2 spacecraft team have narrowed down the near-Earth asteroid’s parent body to one of two larger, more distant asteroids: Polana and Eulalia.

    “Based on links to those specific asteroids, we can talk about the longer history of Ryugu,” said planetary scientist Seiji Sugita of...

    X-ray ‘chimneys’ connect the Milky Way to mysterious gamma-ray bubbles

    Two towering “chimneys” glowing with X-rays extend from the center of the Milky Way. The newly discovered structures could help explain the source of two even larger features: giant bubbles that emit gamma rays, or high-energy light, found above and below the plane of the galaxy.

    Stretching hundreds of light-years, the X-ray chimneys seem to connect the gamma-ray bubbles to the center of...

    In a first, a fossilized egg is found preserved inside an ancient bird

    About 110 million years ago, a sparrow-sized bird died with her egg still inside her body. That egg, crushed and flattened by pressure over time, is the first unlaid bird egg known to be preserved in a fossil, researchers report March 20 in Nature Communications. 

    The fossil was unearthed 11 years ago in northwestern China. In 2018, paleontologists led by Alida Bailleul of the Key...

    Surprising astronomers, Bennu spits plumes of dust into space

    THE WOODLANDS, Texas — Like the “Peanuts” character Pigpen, the near-Earth asteroid Bennu moves around in a cloud of its own dust.

    NASA’s OSIRIS-REx spacecraft has watched Bennu spit out plumes of dust 11 times since the spacecraft arrived at the asteroid in December 2018. And some of that dust is caught in orbit around the asteroid, scientists announced March 19 at the Lunar and...

    The learning gap between rich and poor students hasn’t changed in decades

    The average performance of the lowest income students in the United States lags about three to four years behind that of the highest income students — an achievement gap that has remained constant for more than four decades, a new study finds.

    An analysis of standardized tests given to more than 2.7 million middle and high school students over almost 50 years suggests that federal...

    How a tiger transforms into a man-eater

    No Beast So FierceDane HuckelbridgeWilliam Morrow, $26.99

    At the heart of No Beast So Fierce is a simple and terrifying story: In the early 20th century, a tiger killed and ate more than 400 people in Nepal and northern India before being shot by legendary hunter Jim Corbett in 1907. Rather than just describe this harrowing tale, though, author Dane Huckelbridge seeks to explain how...

    Ultima Thule may be a frankenworld

    THE WOODLANDS, Texas — Ultima Thule’s history may be written in the sum of its parts.

    New analyses suggest that the tiny space rock formed from a rotating cloud of even smaller rocks that collapsed into two individual objects. Those objects then gently collided in the early days of the solar system, creating the distant double-lobed world studied by the passing New Horizons spacecraft,...

    People can sense Earth’s magnetic field, brain waves suggest

    A new analysis of people’s brain waves when surrounded by different magnetic fields suggests that people have a “sixth sense” for magnetism.

    Birds, fish and some other creatures can sense Earth’s magnetic field and use it for navigation (SN: 6/14/14, p. 10). Scientists have long wondered whether humans, too, boast this kind of magnetoreception. Now, by exposing people to an Earth-...

    Meet India’s starry dwarf frog — a species with no close relatives

    A tiny new frog species discovered in tropical forests of southwest India has been one of a kind for millions of years.

    Palaniswamy Vijayakumar and his colleagues first spotted the new species one night in 2010 while surveying frogs and reptiles roughly 1,300 meters up in India’s Western Ghats mountain range. The frog hardly stood out — its brown back, orange belly and starlike spots...

    Resurrecting woolly mammoth cells is hard to do

    Proteins from woolly mammoth cells frozen for 28,000 years in the Siberian tundra may still have some biological activity, claim researchers attempting to clone the extinct behemoths.

    Japanese scientists first extracted nuclei, the DNA-containing compartments of cells, from the muscles of a juvenile woolly mammoth called Yuka, discovered in 2010 in northeast Russia. The team then...
