Tat tech: skin-deep electronics

This is just weird.
It may soon be possible to wear your computer or mobile phone under your sleeve, with the invention of an ultra-thin and flexible electronic circuit that can be stuck to the skin like a temporary tattoo, The Independent reports.
The devices, which are almost invisible, can perform just as well as more conventional electronic machines but without the need for wires or

A fluffy galaxy.


The spiral galaxy NGC 3521 spans 50,000 light-years and holds billions upon billions of blazing stars. Like most spiral galaxies, it's thought to contain a supermassive black hole at its center. It's a swirling maw of raw cosmic power. So how could you call it "fluffy"?

NGC 3521, which is 35 million light-years away in the constellation Leo, is called a flocculent spiral

Infinity in space

A space telescope peering into the Milky Way galaxy’s dusty core has spied a colossal twisted ribbon of supercooled material.

Until now astronomers had only seen bits and pieces of the ribbon’s 600-light-year-wide superstructure, which resembles the symbol for infinity: ∞.


“We have a new and exciting mystery on our hands, right at the center of our own galaxy,” said astronomer Sergio Molinari

You mean it's in my socks?

Killer socks.
The doom and gloom of our current economic crisis can blind us to what lies ahead of us. One part of our future will be nanotechnology, the science of making things at the level of atoms and molecules.

As the research now underway all over the place matures, we may well see:
Sheets of material just a few molecules thick could be made as hard as diamond. Or tiny machines the size

No more reason to believe a scientist than a politician

Mike Haseler, a Scotsman, is an agnostic on global warming, has worked in the "wind industry," was once selected as a candidate by the Green Party, has studied physics and electronics, and has an MBA. He writes.
In the 20th century “science” was without doubt incredibly successful. Everything from microchips to antibiotics. As a result “science” became a reputable brand giving authority to those

Maybe we are the center of the universe

The video below was captured by Stephane Guisard and Jose Francisco Salgado at the European Southern Observatory’s Very Large Telescope (VLT) in Chile’s Atacama Desert.

What makes this time lapse particularly amazing--because we’ve all seen plenty of time lapse videos of the night sky--is the four telescopes in the foreground. Watching these instruments work against a black background would be

The Butterfly Nebula

This celestial object looks like a delicate butterfly. But it is far from serene.

What resemble dainty butterfly wings are actually roiling cauldrons of gas heated to more than 36,000 degrees Fahrenheit. The gas is tearing across space at more than 600,000 miles an hour—fast enough to travel from Earth to the Moon in 24 minutes!


A dying star that was once about five times the mass of the Sun

Is this a new industrial revolution?

Is this going to change everything we know about manufacturing, shopping, garage sales -- the whole economy?

3-D printing is a reality:
Need a whistle right away? Or maybe a Rubik’s cube? How about a new tiny plastic wheel for the dishwasher that you can't find at Home Depot? For a growing number of people, the solution is simply to go online, download a blueprint of the object they desire and

The end is near

If you get up any morning for the next few weeks, you’ll be treated to the sight of all the planets except Saturn arrayed along the ecliptic, the path of the sun through the sky.
For the last two months, almost all the planets have been hiding behind the sun, but this week they all emerge and are arrayed in a grand line above the rising sun. Mercury, Venus, Mars, and Jupiter are visible, and you
