  • 50 years ago, scientists took baby steps toward selecting sex

    Toward preselected sex

    Robert Edwards and Richard Gardner of Cambridge University … say they have been able to remove rabbit embryos … then reimplant only the blastocysts destined to develop into the chosen sex. The implications are obvious and enormous. If this procedure could be extended easily to man there might, for instance, be imbalances, even fads, in the selection by parents...

    This colorful web is the most complete look yet at a fruit fly’s brain cells

    If the secret to getting the perfect photo is taking a lot of shots, then one lucky fruit fly is the subject of a masterpiece.

    Using high-speed electron microscopy, scientists took 21 million nanoscale-resolution images of the brain of Drosophila melanogaster to capture every one of the 100,000 nerve cells that it contains. It’s the first time the entire fruit fly brain has been imaged...

    New ‘Poké Ball’ robot catches deep-sea critters without harming them

    Like a submarine Poké Ball, a new robotic device gently captures and releases deep-sea creatures without a scratch. This critter catcher could be decked out with cameras and other sensors to give scientists an unprecedented view of life in one of Earth’s most mysterious environments. 

    The contraption, designed to be mounted on a remotely operated underwater vehicle, folds into a 12-sided...

    Solving problems by computer just got a lot faster

    A new computer program works smarter, not harder, to solve problems faster than its predecessors.

    The algorithm is designed to find the best solution to a given problem among all possible options. Whereas other computer programs winnow down the possibilities one at a time, the new program — presented July 12 at the International Conference on Machine Learning in Stockholm — rules out...

    Scared of heights? This new VR therapy could help

    Future therapy patients may spend a lot more time exploring virtual environments than sitting on sofas.

    In a clinical trial of a new virtual reality treatment for fear of heights, participants reported being much less afraid after using the program for just two weeks. Unlike other VR therapies, which required that a real-life therapist guide patients through treatment, the new system...

  • 50 years ago, neutrinos ghosted scientists

    Tracking the neutrino

    The definite detection of nonterrestrial neutrinos, whether from the sun or from beyond the solar system, will yield a far deeper understanding of stellar interiors and, therefore, of how today’s universe came to be. — Science News, July 20, 1968.

    Update

    In May 1968, researchers reported that a particle detector in South Dakota spotted ghostly subatomic...

    Readers ask about proton pressure, wearable tech and more

    Pressure gauge

    The pressure inside a proton is the highest of any known substance, Emily Conover reported in “The inside of a proton endures more pressure than anything else we’ve seen” (SN: 6/9/18, p. 10).

    “I don’t think it’s valid to think of pressure on a quantum level the same way we do classically,” Reddit user phazer6 wrote. Pressure relates to collections of particles, but “...

    Designer diamonds could one day help build a quantum internet

    A new kind of artificial diamond is a cut above the rest for quantum memory.

    Unlike other synthetic diamonds, which could either store quantum information for a long time or transmit it clearly, the new diamond can do both. This designer crystal, described in the July 6 Science, could be a key building block in a quantum internet. Such a futuristic communications network would allow...

    NASA’s Parker probe is about to get up close and personal with the sun

    NASA’s Parker Solar Probe is about to embark on one daredevil stunt of a space mission.

    Slated to launch August 4, the probe will be the first spacecraft to swoop through the sun’s outer atmosphere, or corona, a roiling inferno of plasma heated to several million degrees Celsius.

    Parker will whip around the sun two dozen times over the next seven years, skirting within about 6...

  • 50 years ago, a Japanese scientist dreamed up a rocket-propelled train

    Next in speedy trains

    Future trains, in [Hisanojo] Ozawa’s opinion, will all be powered by rockets and run over rollers instead of rails…. His next model will be equipped with three rocket engines and will aim for a speed of 1,180 kilometers an hour, or 0.996 Mach. — Science News, July 6, 1968.

    Update

    A rocket-boosted model train from Ozawa, who designed aircraft for the...
