    Researchers at MIT and Arizona State University have designed a computer program that allows users to translate any free-form drawing into a two-dimensional, nanoscale structure made of DNA. Until now, designing such structures has required technical expertise that puts the process out of reach of most people. Using the new program, anyone can create a DNA nanostructure of any shape, for applications in cell biology, photonics, and quantum sensing and computing, among many others.

    “What this work does is allow anyone to draw literally any 2D shape and convert it into DNA origami automatically,”...

    The first color image of Ultima Thule, taken at a distance of 85,000 miles (137,000 kilometers) at 4:08 Universal Time on January 1, 2019, highlights its reddish surface. At left is an enhanced color image taken by the Multispectral Visible Imaging Camera (MVIC), produced by combining the near infrared, red and blue channels. The center image taken by the Long-Range Reconnaissance Imager (LORRI) has a higher spatial resolution than MVIC by approximately a factor of five. At right, the color has been overlaid onto the LORRI image to show the color uniformity of the Ultima and Thule lobes. Note the reduced red coloring at the neck of the object.

    Researchers for the first time apply catalytic chemical reactions to 2D sheets to generate flows that transform these sheets into mobile, 3D objects. The “magic carpet” featured in tales from “One Thousand and One Nights” to Disney’s “Aladdin” captures the imagination not only because it can fly, but because it can also wave, flap, and alter its shape to serve its riders...

    Juno mission captures images of Volcanic Plumes on Jupiter’s moon Io Light from the plumes and fires of Io on Earth’s darkest night

    January 2, 2019, Categories  Astronomy/Space

    Juno’s Radiation Monitoring Investigation collected this image of Jupiter’s moon Io with Juno’s Stellar Reference Unit (SRU) star camera shortly after Io was eclipsed by Jupiter at 12:40:29 (UTC) Dec. 21, 2018. Io is softly illuminated by moonlight from another of Jupiter’s moons, Europa. The brightest feature on Io is suspected to be a penetrating radiation signature. The glow of activity from several of Io’s volcanoes is seen, including a plume circled in the image.

    A team of space scientists has captured new images of a volcanic plume on Jupiter’s moon Io during the Juno mission’s 17th flyby of the gas giant. On Dec. 21, during winter solstice, four of Juno’s cameras captured images of the Jovian moon Io, the most volcanic body in our solar system...
