A material lighter than air
(20) | 01/08/2015 | Translate: Prof. Ray Baughman and his team of scientists at NanoTech Institute, they have developed a kind of artificial muscle fibers with carbon nanotube growth in dense structure. These fibers have some really outlandish properties. It is lighter than air, stronger than steel and more flexible than rubber.

Carbon fiber durability test Carbon fiber has incredible durability, 10 times larger than steel, but only if they are stretched without bending. Here someone tries to break a bundle of carbon fiber by stretching it with his hands, but the fiber resists and does not break. But when he ties it in a knot, the fiber breaks immediately.- Spiders “winding” the Web as guitar The fibers in the Spider Web vibrate like guitar chords, as scientists say. Playing with the strings and detecting vibrations via sensors in the legs of, a spider gets information about what is on the Web.
- Software reveals the invisible movement A team of scientists at the Massachusetts Institute of technology has developed a video editor, revealing gestures and colors that are invisible to the naked eye.
- Graphene: The strongest material in the world Graphene is a material discovered in 2004 by scientists Andrei Gaim and Konstantin Novoselov, who was also awarded the Nobel Prize in Physics in 2010. Disdyastato is the first material (composed namely of a flat set of carbon atoms), and the strongest known material currently on the planet. Also because they are better conductor of electricity than copper, may has revolutionary uses of computers in industry.
- Steel melting with solar energy Using concentrated solar energy with the help of a huge mirror, the steel melts like butter. In fact this construction located at Sandia Labs in New Mexico, be part of a great experiment. A research team trying to create fuel from thin air, breaking atoms of carbon dioxide with help of solar energy. If this succeeded, then the carbon monoxide arising from fragmentation can be used to create liquid fuels.
- The production of silk Silk is a natural protein fiber produced by the silkworm (the larva of the domesticated silkworm, Bombyx mori). Silk production is a complex process involving many stages. Female silkworms lay eggs, which hatch into larvae. The larvae then feed on mulberry leaves, which provide the necessary nutrients for their cocoons to grow. Silkworms spin their cocoons using a gland, which produces a liquid silk fiber. The fiber hardens on contact with air, forming a continuous thread. The pods are collected and usually boiled or steamed, a process that kills the silkworms and relaxes the silk fibers. The next step is to unravel the silk fibers from the cocoons. The threads are then cleaned and turned into thread, which can be used to weave cloth.
- Special effects without graphics from Terminator 2 Remember the T-1000 from Terminator 2; Throughout the film there were only 3,5 minutes CGI, and the scenes where the bullets hit the liquid metal of the terminator were made without the use of computer graphics. In the 90's the graphics were very expensive and their processing took months. So, the team of special effects created the "craters" with chrome-plated foam rubber. The craters were pressed into a fiberglass container, which closed with a kind of lid which opened by remote control. There are no photos of the device itself, but you can see how it worked in one of the rehearsals.
- The first tests of the vacuum tunnel in South Korea The South Korean Railway Research Institute accelerated a mini train to a record speed of 1.019 km / h, just below the speed of sound (1192 km / h). Scientists expect to launch this new means of transportation on the Seoul-Buzan route in 2024, reducing travel time from 3 hours to 30 minutes.
- Magic in science A chemistry teacher creates carbon dioxide that is heavier than air, and uses it with "Magic" way to blow out four candles.
- Researchers are modeling the spread of particles through the air Aalto University in Finland, the Finnish Meteorological Institute, The VTT Technical Research Center in Finland and the University of Helsinki have studied that extremely small airborne airborne particles are emitted by the respiratory tract when someone coughs., sneezes or even when talking. Such particles can carry pathogens such as coronae. This three-dimensional model shows us the emission of cough particles in a space with shelves, like a supermarket or a library.
- Birth of a chicken from an open egg The process of development of a chicken embryo in an open egg. A scientist injects antibiotics and fluids through the egg, since that is not covered by the shell, and some of the liquid is continuously evaporated.
- Amazing pass in a frisbee match During a match frisbee (American Ultimate Disc League) between Austin and Nashville, the Kyle Henke of Austin has managed to catch the frisbee that came out of the stadium and made a superb ball to the striker while he was in the air. It enabled the team to score in 43 seconds for the end, and Austin eventually won 24-23.
- Using a friction drill Friction drills used to build powerful connections, as it does not remove metal from the hole, but the melt and create a strong wall around the hole. So, a screw can be caught with more bends in the metal and the link to become much stronger. The friction drill bits manufactured from tungsten carbide, a material 3 times stronger than steel. Here our Piet Hein shows how friction works a drill.
- 7 km iceberg detaches from glacier (Greenland) A team of scientists from the University of New York, record video an iceberg length almost 7 kilometers which is detached from a glacier in eastern Greenland. This phenomenon, known as the "birth", is a cause for the rise in seawater level worldwide.
- How spiders use their silk to fly Some species of spiders are able to fly using the technique of balloon flight (ballooning). Ejects a net of silk fibers until the air friction on the fibers is great enough to take off the air and entrains the. These spiders could thus be moved over distances of hundreds of kilometers, even above the sea. A video from the New York Times.
