    Mercury Scout Mission Concept with Solar Sail Propulsion

    The planet Mercury is the closest planet to the Sun, and also the most difficult for spacecraft to visit and explore. This is because as spacecraft get closer to Mercury, the Sun’s enormous gravity pulls in the spacecraft, greatly…

    Scientists just found DNA “supergenes” that speed up evolution

    Researchers have uncovered a powerful genetic mechanism that may help explain how some species evolve with surprising speed. Certain sections of DNA, known as “flipped” segments, appear to help fish rapidly adapt to new environments and even…

  • How squid survived Earth’s biggest extinction and took over the oceans

    How squid survived Earth’s biggest extinction and took over the oceans

    Squid and cuttlefish are among the ocean’s most fascinating animals, known for their color-changing skin and jet-like movement. For decades, scientists have tried to understand how these unusual creatures evolved. Progress has been slow because…

    NASA’s asteroid Bennu sample reveals a hidden chemical patchwork

    A new study shows that, at an incredibly small scale, the building blocks inside the asteroid Bennu are not evenly mixed. Instead, organic material and minerals are grouped into three clearly different chemical regions. These findings help…

  • Cell Lineage Tracing Reveals Early‑Segregated Germline in Plants—-Chinese Academy of Sciences

    August Weismann’s germ plasm theory of the late 19th century posited that only germ cells, e.g., sperm and egg cells in animals or pollen and ovule cells in plants, transmit genetic information to the next generation, and that somatic mutations…

    Abu Dhabi scientists map magnetic waves deep inside the Sun

    Scientists at New York University Abu Dhabi have discovered more kinds of magnetic waves within the Sun.

    The findings may allow them to use these waves to study the powerful forces beneath the Sun’s surface.

    Magnetic fields drive activity such as…
