  • Scientists have found preliminary evidence that tetrahydrocannabinol (THC) and other compounds found in marijuana can promote the cellular removal of amyloid beta, a toxic protein associated with Alzheimer’s disease.

    Sweet. Just in time for we aging hippies.

    Its a pity the stuff makes me paranoid and needs to be avoided…. I had to be sent home early in a cab from a typical Islington dinner party after I unwittingly had the brownies. I insisted my bum was on fire and that I needed to sit in a bath or I could be reduced to a pile of ash.

    NASA + Moog-ISP.

    The Juno Probe is now in Jupiter orbit.

    The US space agency has successfully put a new probe in orbit around Jupiter.

    The Juno satellite, which left Earth five years ago, had to fire a rocket engine to slow its approach to the planet and get caught by its gravity.

    A sequence of tones transmitted from the spacecraft confirmed the braking manoeuvre had gone as planned.

    Receipt of the radio messages prompted wild cheering at Nasa’s Jet Propulsion Laboratory in Pasadena, California.

    “All stations on Juno co-ord, we have the tone for burn cut-off on Delta B,” Juno Mission Control had announced. “Roger Juno, welcome to Jupiter.”

    Scientists plan to use the spacecraft to sense the planet’s deep interior. They think the structure and the chemistry of its insides hold clues to how this giant world formed some four-and-a-half-billion years ago.

    Engineers had warned in advance that the engine firing was fraught with danger.

    No previous spacecraft has dared pass so close to Jupiter; its intense radiation belts can destroy unprotected electronics.

    One calculation even suggested the orbit insertion would have subjected Juno to a dose equivalent to a million dental X-rays.

    But the probe is built like a tank with titanium shielding, and the 35-minute rocket burn appeared to go off without a hitch.
