A step toward safe and reliable autopilots for flying      (via sciencedaily.com)     Original source 

Researchers developed a machine-learning technique that can autonomously drive a car or fly a plane through a very difficult 'stabilize-avoid' scenario, in which the vehicle must stabilize its trajectory to arrive at and stay within some goal region, while avoiding obstacles.

Astronomers discover supernova explosion through rare 'cosmic magnifying glasses'      (via sciencedaily.com)     Original source 

An international team of scientists recently discovered an exceptionally rare gravitationally lensed supernova, which the team named 'SN Zwicky.' Located more than 4 billion light years away, the supernova was magnified nearly 25 times by a foreground galaxy acting as a lens. The discovery presents a unique opportunity for astronomers to learn more about the inner cores of galaxies, dark matter and the mechanics behind universe expansion.

Liquid metal sticks to surfaces without a binding agent      (via sciencedaily.com)     Original source 

Everyday materials such as paper and plastic could be transformed into electronic 'smart devices' by using a simple new method to apply liquid metal to surfaces, according to scientists. The study demonstrates a technique for applying a liquid metal coating to surfaces that do not easily bond with liquid metal. The approach is designed to work at a large scale and may have applications in wearable testing platforms, flexible devices, and soft robotics.

Elusive planets play 'hide and seek' with CHEOPS      (via sciencedaily.com)     Original source 

Astronomers have clearly identified the existence of four new exoplanets. The four mini-Neptunes are smaller and cooler, and more difficult to find than the so-called Hot Jupiter exoplanets which have been found in abundance.

New study identifies mechanism driving the sun's fast wind      (via sciencedaily.com)     Original source 

Researchers used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of 1 million miles per hour. They discovered that the energy released from the magnetic field near the sun's surface is powerful enough to drive the fast solar wind, which is made up of ionized particles -- called plasma -- that flow outward from the sun.

Webb Space Telescope detects universe's most distant complex organic molecules      (via sciencedaily.com)     Original source 

Researchers have detected complex organic molecules in a galaxy more than 12 billion light-years away from Earth -- the most distant galaxy in which these molecules are now known to exist. Thanks to the capabilities of the recently launched James Webb Space Telescope and careful analyses from the research team, a new study lends critical insight into the complex chemical interactions that occur in the first galaxies in the early universe.

Dying stars' cocoons could be new source of gravitational waves      (via sciencedaily.com)     Original source 

Although astrophysicists theoretically should be able to detect gravitational waves from a single, non-binary source, they have yet to uncover these elusive signals. Now researchers suggest looking at a new, unexpected and entirely unexplored place: The turbulent, energetic cocoons of debris that surround dying massive stars.
