Would you fly to space if you could?
|
view preview
The US Federal Aviation Administration (FAA) has just awarded Virginal Galactic their first operating license, allowing them to start using their SpaceShipTwo craft for commercial use - as soon as certain guidelines are met. This means that the company - owned by billionaire Richard Branson - will soon be able to shuttle paying passengers into space. Other than making the flights legal, the license dictates the conditions required before Virgin Galactic can actually let any passengers on board SpaceShipTwo, which will be carried by White Knight Two (below) roughly 99 kilometres (62 miles) into the sky. Once everything is squared away with the FAA, SpaceShipTwo - a spacecraft designed to hold two pilots and six passengers - will hitch a ride w ...

Lysergic acid diethylamide (LSD) is a recreational, psychedelic drug that alter awareness of the surroundings, perceptions, and feelings, as well as sensations and images that seem real though they are not. LSD works by binding primarily to the dopamine receptors and adrenal receptors in the brain. It also binds to most of the serotonin receptors. The binding process is believed to overstimulate the natural neurotransmission process, activating the receptors and altering thought and perceptions. Though medical researchers have not scientifically proven how this process alters consciousness, they are certain about the binding process which links hallucinogenic chemicals to receptors and disrupts neurotransmission between receptors and parts of ...

One step closer to invisibility
|
view preview
Seeing through objects may seem like something straight out of a comic book, but researchers have found a way to make entire animals transparent – from their brains to their bones. The method lets fluorescent proteins visibly shine through bodies, lighting up entire vascular systems (above) and other structures. To produce such light shows, researchers treat euthanized rodents with several organic solvents to remove the water and lipids that made them opaque. The technique is dubbed uDISCO because it’s a variant of the original DISCO technique, which stands for 3D imaging of solvent-cleared organs. This technique allows the highest resolution images yet for a whole body, its creators report online today in Nature Methods, and it can create ...

Is yawning a sign of empathy?
|
view preview
At least to some scientists it is. Scientists believe that catching a yawn is a sign of empathy, since it is more likely to occur between relatives than strangers. Plus, other social primates like chimps and bonobos do it, too. A new study suggests that women (traditionally branded the more empathetic sex) might be more susceptible to copycat yawning than men. Researchers surreptitiously analyzed more than 4000 real-world yawns on planes and trains, in restaurants, and in offices. They noted when someone yawned, and then whether a nearby acquaintance or friend did the same within a 3-minute period. Men and women spontaneously yawned with about the same frequency. But when someone else yawned first, women were more likely than men to follow ...
