Researchers built a 100 Tesla Magnet->

Submitted by Anonymous Coward
An anonymous reader writes "Researchers from Los Alamos Laboratories. they have managed to break the 100 tesla barrier, meaning that the magnet is over 2 million times more powerful than the Earth’s magnetic field.

Chuck Mielke, the director of the Puled field Facility at Los Alamos, said:

"The new magnet has allowed our users and staff to pin down the upper critical field of a new form of superconductor, discover two new magnetically ordered states in a material that has eluded scientists for nearly 30 years, observe magneto-quantum oscillations in a high temperature superconductor to unprecedented resolution, determine a topological state of a new material, and discover a new form of magnetic ordering in an advanced magnetic material.""

Massive Black Holes Fed On Two Accretion Disks->

Submitted by
astroengine
astroengine writes "One of the most enduring mysteries hanging over astrophysics is how supermassive black holes got so big. The leading theory for black hole evolution is that they sucked in huge quantities of matter that formed an accretion disk. This disk supplied the growing black holes with mass. However, there's not enough time in the Universe for black holes to reach millions (or even billions) of times the mass of our sun. So, researchers from England and Australia have modeled a situation where a primordial black hole feeds on two accretion disks. If there's an inner and outer accretion disk skewed at an angle, as they settle and spread, they collide. The collision of matter causes a rapid slowdown, allowing the gravity of the black hole to take over, consuming up to 1,000 times more mass that it would just by feeding off one accretion disk. This may explain how supermassive black holes, that live in the centers of most galaxies, became so big so quickly shortly after the Big Bang. "We don't know exactly how gas flows inside galaxies in the early universe," said Andrew King of the University of Leicester, "but I think it is very promising that if the flows are chaotic it is very easy for the black hole to feed.""

Heat-assisted magnetic recording promises 60-terabyte hard disks->

Submitted by shreshtha
shreshtha writes "Magnetic hard disks will soon be able to store one terabit (a trillion bits) per square inch. Seagate has demonstrated that landmark storage density using a new magnetic recording method that can cram 10 terabits, and perhaps even more, onto every inch of a standard 3.5-inch disk. Disks made with current technology can hold about 3 terabytes.

The technology, called heat-assisted magnetic recording, involves heating the magnetic regions on a disk that hold individual data bits, allowing those regions to be made tinier. Seagate says the method promises to keep increasing storage density, and it could lead to 60-terabyte hard drives."

not just medical examination. it is just a co-incidence that the medical profession is one that is tangled with most examinations. speaking of examinations, though, the most important examination for us medical doctors are usually conducted in the oral style (viva examination) which allowed impromptu questions set immediately, testing the doctor on how they would handle a patient step-by-step. i'm not sure about the american system but that's true for most british systems.

<quote>REAL GLASS fiber optics are heavier than copper cable, with the approximate atomic weight of copper being 29 and silicon dioxide being 30 having two oxygen atoms at 8 and one silicon atom at 14.</quote>

atomic mass has little to do with the mass density of solid structure, for the matter. For plastics it is even a more complicated matter, even for plastics made of a single monomer, depending on the condition the plastic is formed there may be different density.

Designer Accused of Copying His Own Work By Stock Art Website 380

Posted by Soulskill
from the only-so-many-ambulances-can-be-chased dept.
the_harlequin writes "A successful designer, who has a showcase of his own work available online, has had a stock image site accuse him of copyright infringement over his own illustrations, citing damages of $18,000. The story doesn't end there; the stock photo site hired lawyers, who have contacted the original designer's clients. The lawyers told them the designer is being investigated for copyright infringement and their logos might be copied, thus damaging his reputation. 'My theory is that someone copied my artwork, separated them from any typography and then posted them for sale on the stock site. Someone working for the site either saw my [LogoPond] showcase or was alerted to the similarities. They then prepared the bill and sent it to me. The good thing is that the bill gives me a record of every single image they took from me. That helps me gather dates, sketches, emails, etc. to help me prove my case. The bad thing is that despite my explanations and proof, they will not let this go.'"
