Black Holes Physics Described By Researchers
2012-12-12 09:42:37

April Flowers for redOrbit.com - Your Universe Online Many mysteries surround black holes, but new research led by the Niels Bohr Institute has come up with groundbreaking new theories that might explain several of their more mysterious properties. The new study reveals that black holes have properties that resemble the dynamics of both solids and liquids. Black holes are extremely compact, so compact in fact that they generate an incredibly strong gravitational pull. Everything that...

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life. Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society. “One of our long...

Lianas whose stabilization rings of woody cells heal spontaneously after suffering damage serve as a natural example to bionic experts of self-repairing membranes. Such membranes could find use, for example, in rubber dinghies. Empa researchers have borrowed this trick from nature and developed a polymer foam surface coating with a closed cell construction which not only reduces the pressure loss after the membrane is damaged but also makes the inflatable structure more resistant and giving...

Microscopically porous polymer membranes have numerous applications in microfluidics, where they can act as filters, masks for surface patterning, and even as components in 3D devices in which the perforations in stacked membranes are aligned to form networks of channels for the flow of fluids. In the AIP journal Biomicrofluidics, Hongkai Wu, a chemist at Hong Kong University of Science and Technology, and his colleagues describe a simple new method using just one photolithographic step to...

X-rays are the medium of choice for many scientific studies. When you shine them on a sample, they literally shed light on the material's structure, providing loads of information about it. Unfortunately, this mostly applies to solids only, since the sample has to be in a vacuum for the entire time it is being irradiated with soft X-rays. For liquids, that means you have to remove all the water. In the case of biological samples such as proteins, however, this destroys their natural...

LONDON, March 10 /PRNewswire/ -- Based on its recent analysis of the biomimetic membranes market, Frost & Sullivan recognises Aquaporin A/S with the "2009 European Biomimetic Membranes Technology Innovation Award." The demand for high-purity water separation across a wide variety of industries is likely to establish Aquaporin Membranes, a novel biomimetic membrane that is embedded with aquaporins, as the standard equipment for membrane separation.

CHAMPAIGN, Ill. -- Ancient light absorbed by neutral hydrogen atoms could be used to test certain predictions of string theory, say cosmologists at the University of Illinois. Making the measurements, however, would require a gigantic array of radio telescopes to be built on Earth, in space or on the moon. String theory "“ a theory whose fundamental building blocks are tiny one-dimensional filaments called strings "“ is the leading contender for a "theory of everything." Such...

Washington -- Physicists who work with a concept called string theory envision our universe as an eerie place with at least nine spatial dimensions, six of them hidden from us, perhaps curled up in some way so they are undetectable. The big question is why we experience the universe in only three spatial dimensions instead of four, or six, or nine. Two theoretical researchers from the University of Washington and Harvard University think they might have found the answer. They believe the way...

M-Theory -- 'M-Theory' is the name of the unknown theory of everything which would combine all five Superstring theories and the Supergravity at 11 dimensions together. The theory requires mathematical tools which have yet to be invented in order to be fully understood. The theory was proposed by Edward Witten. The following article is somewhat technical in nature, see M-theory simplified for a less technical article. M-theory's relation to superstrings and supergravity...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
