    A space rock collision may explain how this exoplanet was born

    Cataclysmic collisions between space rocks have helped explain some of the solar system’s biggest mysteries, from how the moon formed to how Uranus got its lopsided rotation. But convincing evidence for such events happening outside of the solar system is scant.

    Now scientists think that they have found the first known example of a near head-on collision between two massive worlds in...

    Known as the ‘mother of Hubble,’ astronomer Nancy Roman dies at 93

    Nancy Roman, a groundbreaking astronomer known as the “Mother of Hubble,” died on December 25 at the age of 93.As NASA’s first Chief of Astronomy, Roman oversaw the early planning and development of the Hubble Space Telescope (SN: 10/10/64, p. 231) as well as other space observatories and satellites. “I knew that taking on this responsibility would mean that I could no longer do research, but...

    Tumor ‘organoids’ may speed cancer treatment

    SAN DIEGO — Collecting cancer cells from patients and growing them into 3-D mini tumors could make it possible to quickly screen large numbers of potential drugs for ultra-rare cancers. Preliminary success with a new high-speed, high-volume approach is already guiding treatment decisions for some patients with recurring hard-to-treat cancers.

    “Believe it or not, for some rare cancers...

    A new airplane uses charged molecules, not propellers or turbines, to fly

    A newly designed airplane prototype does away with noisy propellers and turbines.

    Instead, it’s powered by ionic wind: charged molecules, or ions, flowing in one direction and pushing the plane in the other. That setup makes the aircraft nearly silent. Such stealth planes could be useful for monitoring environmental conditions or capturing aerial imagery without disturbing natural...

    Mini ‘solar panels’ help yeast shine at churning out drug ingredients

    Bionic microbes outfitted with tiny semiconductor components can generate useful chemicals more efficiently than normal cells.

    Microorganisms like fungi are commonly used in biomanufacturing to convert simple carbon-based molecules, such as sugar, into a wide range of chemical ingredients for pharmaceuticals and other products. But much of a microbe’s carbon intake typically gets used to...

    These tiny, crackly bubbles are a new type of volcanic ash

    Bread-crust bubble\Bred krəst ˈbəb(ə)l\ n.

    Tiny, gas-filled beads of volcanic ash with a scaly surface.

    Scientists have identified a new type of volcanic ash that erupted from a volcano in central Oregon roughly 7 million years ago. The particles are similar to larger bread-crust bombs, which form as gases trapped inside globs of lava expand, cracking the bombs’ tough exterior. Bread-...

    A new palm-sized drone is mini, but mighty

    A new type of mini drone can pull a lot more than its own weight.

    The drone latches onto a surface and uses a cable to reel in objects up to 40 times its mass, researchers report. This feat is a marked improvement over other flying robots, which generally can’t tote objects heavier than about their own weight (SN: 2/7/15, p. 18). The new palm-sized flyer, described October 24 in Science...

    The universe’s continued existence implies extra dimensions are tiny

    This could be the way the world ends.

    First, a pair of cosmic protons smash together at unimaginable speeds. The tremendous energy of their crash would create a tiny, ephemeral black hole, so small that it would last just a fraction of a second before evaporating.

    Where the black hole just was, a bubble of space with entirely different laws of physics than the universe we inhabit...

    Japan has launched a miniature space elevator

    A pair of tiny satellites that will help test technology for a space elevator is on its way to the International Space Station.

    At 1:52 p.m. EDT on September 22, the Japan Aerospace Exploration Agency launched a rocket carrying the STARS-Me experiment from the island of Tanegashima.

    STARS-Me (or Space Tethered Autonomous Robotic Satellite – Mini elevator), built by engineers at...

    Scientists successfully transplant lab-grown lungs into pigs

    For the first time, researchers have created lungs in the lab and successfully transplanted them into pigs.

    These bioengineered lungs, described online August 1 in Science Translational Medicine, developed healthy blood vessels that allowed pigs to live for several weeks after surgery. That’s a significant improvement from previous efforts: Lab-grown lungs implanted in rodents failed...
