    Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way.

    Their findings are published today (Nov...

    Brain Changes in Autism are far more sweeping than previously known, study finds

    November 4, 2022, Categories  Health/Medical, Biology/Biotechnology

    This shows a brain
    The new study finds brain-wide changes in virtually all of the 11 cortical regions analyzed, regardless of whether they are higher critical association regions – those involved in functions such as reasoning, language, social cognition and mental flexibility – or primary sensory regions. Image is in the public domain

    Brain changes in autism are comprehensive throughout the cerebral cortex rather than just particular areas thought to affect social behavior and language, according to a new UCLA-led study that significantly refines scientists’ understanding of how autism spectrum disorder (ASD) progresses at the molecular level.

    The study, published today in Nature, represents a comprehensive effort to characterize ASD at the molecular level...

    A research team based out of the University of Waterloo has developed a drone-powered device that can use Wi-Fi networks to see through walls. The device, nicknamed Wi-Peep, can fly near a building and then use the inhabitants’ Wi-Fi network to identify and locate all Wi-Fi-enabled devices inside in a matter of seconds.

    The Wi-Peep exploits a loophole the researchers call polite Wi-Fi. Even if a network is password protected, smart devices will automatically respond to contact attempts from any device within range...

    Researchers’ recent observations of a stellar-mass black hole called Cygnus X-1 reveal new details about the configuration of extremely hot matter in the region immediately surrounding the black hole.

    Matter is heated to millions of degrees as it is pulled toward a black hole. This hot matter glows in X-rays...
