Keen On? We Are Not In A Bubble (TCTV)
No, we are not in a bubble. Not, at least, according to the Kleiner-Perkins partner, Chi-Hua Chien, who spoke at our Mobile First CrunchUp event in Palo Alto last Friday. Indeed, as Chien told me after his CrunchUp panel, he views today?s two great investment sectors ? in mobile and in social ? as unique opportunities to reinvent all Internet businesses. According to Chien, everything is going mobile and everything is going social. Which is why, of course, Kleiner has set up two funds ? its iFund and its sFund especially for mobile and social. And it?s why, as Chien explained to me, that Kleiner wants to invest in what he calls those ?super verticals? that enable ?amazing? mobile and social experiences.

Manipulating light at will
Monday, August 1, 2011
Electrical engineers at Duke University have developed a material that allows them to manipulate light in much the same way that electronics manipulate flowing electrons.
The researchers say the results of their latest proof-of-concept experiments could lead to the replacement of electrical components with those based on optical technologies. Light-based devices would enable faster and more efficient transmission of information, much in the same way that replacing wires with optical fibers revolutionized the telecommunications industry.
The breakthrough revolves around a novel man-made structure known as a metamaterial. These exotic composite materials are not so much a single substance, but an entire structure that can be engineered to exhibit properties not readily found in nature. The structure used in these experiments resembles a miniature set of tan Venetian blinds.
When light passes through a material, even though it may be reflected, refracted or weakened along the way, it is still the same light coming out. This is known as linearity.
"For highly intense light, however, certain 'nonlinear' materials violate this rule of thumb, converting the incoming energy into a brand new beam of light at twice the original frequency, called the second-harmonic," said Alec Rose, graduate student in the laboratory of David R. Smith, William Bevan Professor of electrical and computer engineering at Duke's Pratt School of Engineering.
As an example, he cited the crystal in some laser pointers, which transforms the normal laser light into another beam of a different color, which would be the second-harmonic. Though they contain nonlinear properties, designing such devices requires a great deal of time and effort to be able to control the direction of the second harmonic, and natural nonlinear materials are quite weak, Rose said.
"Normally, this frequency-doubling process occurs over a distance of many wavelengths, and the direction in which the second-harmonic travels is strictly determined by whatever nonlinear material is used," Rose said. "Using the novel metamaterials at microwave frequencies, we were able to fabricate a nonlinear device capable of 'steering' this second-harmonic. The device simultaneously doubled and reflected incoming waves in the direction we wanted."
The research results were published online in the journal Physical Review Letters. It was supported by the Air Force Office of Scientific Research. Smith's team was the first to demonstrate that similar metamaterials could act as a cloaking device in 2006 and a next generation lens in 2009.
"This magnitude of control over light is unique to nonlinear metamaterials, and can have important consequences in all-optical communications, where the ability to manipulate light is crucial," Rose said.
The device, which measures six inches by eight inches and about an inch high, is made of individual pieces of the same fiberglass material used in circuit boards arranged in parallel rows. Each piece is etched with copper circles. Each copper circle has a tiny gap that is spanned by a diode, which when excited by light passing through it, breaks its natural symmetry, creating non-linearity.
"The trend in telecommunications is definitely optical," Rose said. "To be able to control light in the same manner that electronics control currents will be an important step in transforming telecommunications technologies."

Grapes protect against ultraviolet radiation
Friday, July 29, 2011
Some compounds found in grapes help to protect skin cells from the sun's ultraviolet radiation, according to a study by researchers from the University of Barcelona and the CSIC (Spanish National Research Council). The study supports the use of grapes or grape derivatives in sun protection products.
Ultraviolet (UV) rays emitted by the sun are the leading environmental cause of skin complaints, causing skin cancer, sunburn and solar erythema, as well as premature ageing of the dermis and epidermis. Now, a Spanish study has proven that some substances in grapes can reduce the amount of cell damage caused in skin exposed to this radiation.
UV rays act on the skin by activating 'reactive oxygen species' (ROS). These compounds in turn oxidise macromolecules such as lipids and DNA, stimulating certain reactions and enzymes (JNK and p38MAPK) which cause cell death.
A group of scientists from the University of Barcelona and the CSIC have shown that some polyphenolic substances extracted from grapes (flavonoids) can reduce the formation of ROSs in human epidermis cells that have been exposed to long-wave (UVA) and medium-wave (UVB) ultraviolet radiation. The study, carried out in vitro in the laboratory, has been published in the Journal of Agricultural and Food Chemistry.
Grape-based sun protection
"These polyphenolic fractions inhibit the generation of the ROSs and, as a result, the subsequent activation of the JNK and p38 enzymes, meaning they have a protective effect against ultraviolet radiation emitted by the sun", Marta Cascante, a biochemist at the University of Barcelona (Spain) and director of the research project, tells SINC.
The researchers found that the higher the degree of the flavonoids' polymerisation and formation of compounds containing gallic acid, the greater their photoprotective capacity.
The study suggests that these "encouraging results should be taken into consideration in clinical pharmacology using plant-based polyphenolic extracts to develop new photoprotection skin products.
Cosmetics and drugs containing grape compounds are already available, but the way they act on cells has not been well understood until now. "This study supports the idea of using these products to protect the skin from cell damage and death caused by solar radiation, as well as increasing our understanding of the mechanism by which they act", concludes Cascante.
