The researchers were polishing a slice of the carbon-rich Havero meteorite that fell to Earth in Finland in 1971. When they then studied the polished surface they discovered carbon-loaded spots that were raised well above the rest of the surface –- suggesting that these areas were harder than the diamonds used in the polishing paste.
"That in itself is not surprising," said diamond researcher Changfeng Chen of the University of Nevada in Las Vegas. He explained that sometimes during the shock of impact graphite can create jumbled "amorphous" zones that can resist diamonds, at least those coming at them from one direction.
But what apparently happened in the Havero meteorite is that graphite layers were shocked and heated enough to create bonds between the layers -- which is exactly how humans manufacture diamonds, Chen explained.
Ferroir's team took the next step and put the diamond-resistant crystals under the scrutiny of some very rigorous mineralogical analyzing instruments to learn how its atoms are lined up. That allowed them to confirm that they had, indeed, found a new "phase" or polymorph of crystalline carbon as well as a type of diamond that had been predicted to exist decades ago, but had never been found in nature until now.
The different colours were created by adding no, little or lots of milk to each cup of black coffee.
It measures an impressive 20 feet high and 13 feet wide and took a team of eight people three hours to complete.
"Most of the fish we catch are better to eat, but they don't give you much of a fight."
He said the squid were "trying to crawl around and blow ink all over everybody."
Mr Woodbury said that 400 of the creatures had been caught since Friday night.
The animals weigh between 20 and 40 pounds, but a few fishermen have reeled in 60-pound squid.
The Humboldt squid is also called the jumbo squid or jumbo flying squid and squirts ink to protect itself.
They can grow up to 100 pounds in weight and six feet long and follow food sources.
But seriously, while going through Art History class I had a hard time NOT thinking of the Ninja Turtles. They may or may not have been doodled into the margins next to Brunelleschi’s perspective business.
Henrietta’s cells were the first immortal human cells ever grown in culture. They were essential to developing the polio vaccine. They went up in the first space missions to see what would happen to cells in zero gravity. Many scientific landmarks since then have used her cells, including cloning, gene mapping and in vitro fertilization.
This is probably the most fun road you can travel on four wheels, and then maybe on your two legs checking out the various hiking trails leading from the area. In fact, this might be considered the most breathtaking place in Europe. It all starts with the narrow road up the steep walls of the Lysefjord, Norway. It has 27 switchbacks and a 1.1 km long tunnel at the bottom, with 3 switchbacks inside. The last 30 km of Lysebotn road is a true roller-coaster! It’s narrow but has a perfect surface, winding left and right all the time. If you happen to ride a motorcycle in Norway, then this is the road you simply cannot afford to miss!
Most Illustrious Lord, Having now sufficiently considered the specimens of all those who proclaim themselves skilled contrivers of instruments of war, and that the invention and operation of the said instruments are nothing different from those in common use: I shall endeavor, without prejudice to any one else, to explain myself to your Excellency, showing your Lordship my secret, and then offering them to your best pleasure and approbation to work with effect at opportune moments on all those things which, in part, shall be briefly noted below.
1. I have a sort of extremely light and strong bridges, adapted to be most easily carried, and with them you may pursue, and at any time flee from the enemy; and others, secure and indestructible by fire and battle, easy and convenient to lift and place. Also methods of burning and destroying those of the enemy.
2. I know how, when a place is besieged, to take the water out of the trenches, and make endless variety of bridges, and covered ways and ladders, and other machines pertaining to such expeditions
Rough traffic accident calculations show that by inserting two pieces of her composite metal foam behind the bumper of a car traveling 28 mph, the impact would feel the same to passengers as impact traveling at only 5 mph.[...]
The results are most striking when the material is tested in a lab. The test itself is exciting: a high-powered machine smashes a piece of steel foam straight down into the base plate of the machine, and then does the same thing with a piece of bulk steel.
When she examines the base plates under both samples, there’s a clear indentation left under the bulk steel sample, while the plate under the foam shows no indentation. The test shows how the foam absorbed the energy and protected the plate, while the steel simply transferred it to the base plate with no protection.
