Quantum levitation

Hmmm! Rather “cool” video of quantum locking of superconducting magnets. IOW, magnets that float and move in a locked position relative to other magnets.

Alcohol sharpens the mind

Eureka! Drink up.

The drinking group solved nearly 40 per cent more problems than the others, and took an average of 12 seconds compared to the 15.5 seconds needed by sober subjects.

The most complex mass of protoplasm in the Milky Way?

Our data may open up entirely new ways of analyzing, understanding, and, eventually, imitating the network architecture of the brain, which according to Marian C. Diamond and Arnold B. Scheibel is “the most complex mass of protoplasm on earth—perhaps even in our galaxy.”

12-mile-high martian dust devil caught in act

A Martian dust devil roughly 12 miles high 20 kilometers was captured whirling its way along the Amazonis Planitia region of Northern Mars on March 14…They are spinning columns of air, made visible by the dust they pull off the ground. Unlike a tornado, a dust devil typically forms on a clear day when the ground is heated by the sun, warming the air just above the ground.

1,000,000,000,000,000,000 bytes of astronomical data per day

Thunderbolt SSD RAIDs, anyone?

…the SKA represents a new step in terms of data management and the complexities of project coordination.  The instrument will generate an exabyte of data every day – that would be 1,000,000,000,000,000,000 bytes – more than twice the information sent around the internet on a daily basis and 100 times more information than the LHC produces.

Planet Mercury even weirder than we thought

 

…two new papers show that the planet had active geologic and tectonic processes occurring until at least the planet’s middle age, around 2 billion years ago.

Mayan doom teaches climate lesson

…these droughts may not have been strong enough to cause by themselves the collapse of the civilization, but they were likely strong enough and persistent enough … to cause major sociopolitical disruptions that ultimately led to the final outcome.

Brain and eye abnormalities in astronauts

No mention of whether the damage resulting from long-term exposure to microgravity is permanent. Some version of artificial gravity may be a prerequisite to long-term space travel.

Rare galaxy at ‘dawn of time’

Astronomers using NASA’s Spitzer and Hubble space telescopes have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate. The blob-shaped galaxy, called GN-108036, is the brightest galaxy found to date at such great distances.
