Scientists figured out how shrooms open your mind

It’s one thing to say that psychedelic mushrooms "open your mind," but it’s another entirely to demonstrate its dream-like effects in a scientific study. Yet, that’s what one group of researchers appear to have achieved in a study published today in <i>Human Brain Mapping</i>.<p>these effects are akin to what …

Astronomers Are Closer to Understanding Dark Matter

Astronomers have come closer to understanding dark matter — one of the most elusive substances in the universe — by using high-energy telescopes to …

As a birder, this made me laugh.

APOD: Martian Anniversary Selfie (2014 Jun 27) Image Credit: NASA, JPL-Caltech, MSSS http://apod.nasa.gov/apod/ap140627.html Explanation: June 24th marked the first full Martian year of the Curiosity Rover's exploration of the surface of the Red Planet. That's 687 Earth days or 669 sols since its landing on August 5, 2012. To celebrate, consider this self-portrait of the car-sized robot posing next to a rocky outcrop dubbed Windjana, its recent drilling and sampling site. The mosaicked selfie was constructed with frames taken this April and May using the rover's Mars Hand Lens Imager (MAHLI), intended for close-up work and mounted at the end of the rover's robotic arm. The MAHLI frames used exclude sections that show the arm itself and so MAHLI and the robotic arm are not seen. Famous for panoramic views, the rover's Mastcam is visible though, on top of the tall mast staring toward the left and down at the drill hole. http://www.nasa.gov/ http://www.jpl.nasa.gov/ http://www.msss.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140627 #APOD

Astronomers discover Earth-sized 'diamond' 900 light years away

The world's largest diamond, the Cullinan, is a tad over 3,100 carats uncut. Its estimated value is some $2 billion, and it only weighs about 1.37 pounds. That stone, while enormous relative to others like it, is but an invisible speck when up against the Earth-sized diamond discovered 900 light …

APOD: Halo of the Cat's Eye (2014 Jun 01) Image Credit & Copyright: R. Corradi (Isaac Newton Group), Nordic Optical Telescope http://apod.nasa.gov/apod/ap140601.html Explanation: The Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its haunting symmetries are seen in the very central region of this stunning false-color picture, processed to reveal the enormous but extremely faint halo of gaseous material, over three light-years across, which surrounds the brighter, familiar planetary nebula. Made with data from the Nordic Optical Telescope in the Canary Islands, the composite picture shows extended emission from the nebula. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. Only much more recently however, have some planetaries been found to have halos like this one, likely formed of material shrugged off during earlier active episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years. http://www.ing.iac.es/ http://www.not.iac.es/general/photos/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140601 #APOD

Human 'suspended animation' trials to start this month

The researchers behind it don't want to call it suspended animation, but it's the most conventional way to explain it. The world's first humans trials will start at the UPMC Presbyterian Hospital in Pittsburgh, with 10 patients whose injuries would otherwise be fatal to operate on. A team of …
