Jon Jones, Pat Healy and Sara McMann: UFC 159?s Three Stars
UFC 159 was a bizarre event ? possibly cursed by demons ? but there were still plenty of standout performances by fighters whose bouts ended normally. Who stood out for you? Speak up on Twitter or on Facebook.
No. 1 star -- Jon Jones: As we've said since the fight was made, Chael Sonnen was not the right competition for UFC light heavyweight Jones because he is middleweight coming off of a loss. Jones could have taken Sonnen lightly and still probably won, but he didn't do that. He used the fight as another opportunity to show his dominance, beating Sonnen at his own game by taking him down several times before finishing the fight near the end of the first round.
Would the fight have been stopped if they made it out of the first round, and the referee had noticed Jones' mangled toe? Who cares? It didn't happen, and Jones is still the champ.
No. 2 star -- Pat Healy: The UFC's already stacked lightweight division somehow got even tough with Healy's performance on Saturday night. Along with Jim Miller, he put on a show then finished the fight in the third round. He won both Fight of the Night and Submission of the Night, meaning Healy walked away with an extra $130,000.
No. 3 star -- Sara McMann: As an Olympic silver medal-winning wrestler, McMann is one of the most decorated athletes to join the UFC. This means she had big expectations to perform, and she exceeded them. McMann used wrestling and power to stop Sheila Gaff in the first round.

Sprint seeks details from Dish on takeover proposal
By Liana B. Baker and Ben Berkowitz
(Reuters) - Sprint Nextel Corp on Monday said its merger partner, SoftBank Corp, has waived some terms of their agreement so that Sprint can seek more information from rival suitor Dish Network Corp.
The exchange of information between Sprint and Dish indicates the companies are in conversations about the satellite broadcaster's $25.5 billion takeover bid, even if Sprint for now is standing by its $20.1 billion pact with SoftBank.
Dish said it had received a Sprint request for more information about the bid, and a non-disclosure agreement that would keep such information private.
Dish said it had already given some information to Sprint in response to requests from a Sprint special committee.
SoftBank said the waiver it granted does not allow Sprint to disclose nonpublic information or negotiate with Dish.
But Dish said it looks "forward to being able to conduct confirmatory due diligence as soon as possible" with Sprint.
Dish shocked markets two weeks ago with its cash and stock offer for Sprint, which it claimed was superior to the deal SoftBank and Sprint struck last October. Sprint said it had formed a special board committee and hired advisers to consider the Dish bid. But it also said it was still on track to close its deal with SoftBank by July 1.
SoftBank, in a statement, said it had issued the waiver at the request of Sprint's special committee and reiterated its intent to proceed with the deal.
"SoftBank remains highly confident that its fully executed merger agreement with Sprint, under which it has already provided Sprint with $3.1 billion of capital, provides the shareholders of Sprint significantly more value than the highly leveraged approach made by Dish on April 15th," it said.
Dish Chairman Charlie Ergen said in a statement that Dish was "confident that the Sprint Board will share our view that this proposal is superior by offering Sprint shareholders greater value with a higher price and more cash."
Dish shares were up 0.8 percent at $40.32 in afternoon trading, while Sprint shares were off 1 cent at $7.11.

Researchers design nanometer-scale material that can speed up, squeeze light
Apr. 29, 2013 ? In a process one researcher compares to squeezing an elephant through a pinhole, researchers at Missouri University of Science and Technology have designed a way to engineer atoms capable of funneling light through ultra-small channels.
Their research is the latest in a series of recent findings related to how light and matter interact at the atomic scale, and it is the first to demonstrate that the material -- a specially designed "meta-atom" of gold and silicon oxide -- can transmit light through a wide bandwidth and at a speed approaching infinity. The meta-atoms' broadband capability could lead to advances in optical devices, which currently rely on a single frequency to transmit light, the researchers say.
"These meta-atoms can be integrated as building blocks for unconventional optical components with exotic electromagnetic properties over a wide frequency range," write Dr. Jie Gao and Dr. Xiaodong Yang, assistant professors of mechanical engineering at Missouri S&T, and Dr. Lei Sun, a visiting scholar at the university. The researchers describe their atomic-scale design in the latest issue of the journal Physical Review B.
The researchers created mathematical models of the meta-atom, a material 100 nanometers wide and 25 nanometers tall that combined gold and silicon oxide in stairstep fashion. A nanometer is one billionth of a meter and visible only with the aid of a high-power electron microscope.
In their simulations, the researchers stacked 10 of the meta-atoms, then shot light through them at various frequencies. They found that when light encountered the material in a range between 540 terahertz and 590 terahertz, it "stretched" into a nearly straight line and achieved an "effective permittivity" known as epsilon-near-zero.
Effective permittivity refers to the ratio of light's speed through air to its speed as it passes through a material. When light travels through glass, for instance, its effective permittivity is 2.25. Through air or the vacuum of outer space, the ratio is one. That ratio is what is typically referred to as the speed of light.
As light passes through the engineered meta-atoms described by Gao and Yang, however, its effective permittivity reaches a near-zero ratio. In other words, through the medium of these specially designed materials, light actually travels faster than the speed of light. It travels "infinitely fast" through this medium, Yang says.
The meta-atoms also stretch the light. Other materials, such as glass, typically compress optical waves, causing diffraction.
This stretching phenomenon means that "waves of light could tunnel through very small holes," Yang says. "It is like squeezing an elephant through an ultra-small channel."
The wavelength of light encountering a single meta-atom is 500 nanometers from peak to peak, or five times the length of Gao and Yang's specially designed meta-atoms, which are 100 nanometers in length. While the Missouri S&T team has yet to fabricate actual meta-atoms, they say their research shows that the materials could be built and used for optical communications, image processing, energy redirecting and other emerging fields, such as adaptive optics.
Last year, Albert Polman at the FOM Institute for Atomic and Molecular Physics in Amsterdam and Nader Engheta, an electrical engineer at the University of Pennsylvania, developed a tiny waveguide device in which light waves of a single wavelength also achieved epsilon-near-zero. But the Missouri S&T researchers' work is the first to demonstrate epsilon-near-zero in a broadband of 50 terahertz.
"The design is practical and realistic, with the potential to fabricate actual meta-atoms," says Gao. Adds Yang: "With this research, we filled the gap from the theoretical to the practical."
Through a process known as electron-beam deposition, the researchers have built a thin-film wafer from 13 stacked meta-atoms. But those materials were uniform in composition rather than arranged in the stairstep fashion of their modeled meta-atoms.

A study in The Journal of General Physiology presents new methods to evaluate how astrocytes contribute to brain function, paving the way for future exploration of these important brain cells at unprecedented levels of detail.
Astrocytesthe most abundant cell type in the human brainplay crucial roles in brain physiology, which may include modulating synaptic activity and regulating local blood flow. Existing research tools can be used to monitor calcium signals associated with interactions between astrocytes and neurons or blood vessels. Until now, however, astrocytic calcium signals have been investigated mainly in their somata (cell bodies) and large processes, rather than in distal fine processes close to neuronal synapses or the endfeet that surround blood vessels. Previous studies have also mainly investigated immature specimens rather than mature brain cells.
Now, a team of California researchers provides detailed methods to visualize calcium signals throughout entire astrocytes in hippocampal slices from adult mice. The team observed numerous spontaneous localized calcium signals throughout the entire astrocyte, including the branchlets and endfeet. Their results indicated that calcium signals in endfeet were independent of those in somata and occurred more frequently. In addition to the specific findings, their methods can be used in future studies to advance our understanding of the physiology of astrocytes and their interactions with neurons and the microvasculature of the brain.
