Made in IBM Labs: IBM Lights Up Silicon Chips to Tackle Big Data

• From the Lab to the Fab: Technology Breakthrough Demonstrates Feasibility of Silicon Nanophotonics for Chip Manufacturing
• Light Pulses Can Move Data at Blazing Speeds to Help Solve Bandwidth Limitations of Servers, Datacenters and Supercomputers
• After More Than a Decade of Research, Silicon Nanophotonics is Ready for Development of Commercial Applications

SAN FRANCISCO, Calif. – 10 Dec 2012: IBM announced today a major advance in the ability to use light instead of electrical signals to transmit information for future computing. The breakthrough technology – called “silicon nanophotonics” – allows the integration of different optical components side-by-side with electrical circuits on a single silicon chip using, for the first time, sub-100nm semiconductor technology.

Silicon nanophotonics takes advantage of pulses of light for communication and provides a super highway for large volumes of data to move at rapid speeds between computer chips in servers, large datacenters, and supercomputers, thus alleviating the limitations of congested data traffic and high-cost traditional interconnects.

Mastering Scientific Mumbo Jumbo

About the video: Discusses the interaction between abiotic and biotic factors. The style of the animation is influenced by The Common Craft Show.

Warning: This class will teach students to translate scientific mumbo jumbo into understandable phrases.

Michigan State University’s first, free Massive Open Online Course, or MOOC, also promises to then teach students “to speak mumbo jumbo and amaze your friends.” (more…)

NASA’s GRAIL Creates Most Accurate Moon Gravity Map

PASADENA, Calif. — Twin NASA probes orbiting Earth’s moon have generated the highest resolution gravity field map of any celestial body.

The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon’s internal structure and composition in unprecedented detail. Data from the two washing machine-sized spacecraft also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.

The gravity field map reveals an abundance of features never before seen in detail, such as tectonic structures, volcanic landforms, basin rings, crater central peaks and numerous simple, bowl-shaped craters. Data also show the moon’s gravity field is unlike that of any terrestrial planet in our solar system. (more…)

Moths Wired Two Ways to Take Advantage of Floral Potluck

Moths are able to enjoy a pollinator’s buffet of flowers – in spite of being among the insect world’s picky eaters – because of two distinct “channels” in their brains, scientists at the University of Washington and University of Arizona have discovered.

One olfactory channel governs innate preferences of the palm-sized hawk moths that were studied – insects capable of traveling miles in a single night in search of favored blossoms. The other allows them to learn about alternate sources of nectar when their first choices are not available.

For moths, the ability to seek and remember alternate sources of food helps them survive harsh, food-deprived conditions. Scientists knew bees could learn, but this is the first proof that moths can too. (more…)

Another Muscular Dystrophy Mystery Solved; MU Scientists Inch Closer to a Therapy for Patients

COLUMBIA, Mo. — Approximately 250,000 people in the United States suffer from muscular dystrophy, which occurs when damaged muscle tissue is replaced with fibrous, bony or fatty tissue and loses function. Three years ago, University of Missouri scientists found a molecular compound that is vital to curing the disease, but they didn’t know how to make the compound bind to the muscle cells. In a new study, published in the Proceedings of the National Academies of Science, MU School of Medicine scientists Yi Lai and Dongsheng Duan have discovered the missing pieces to this puzzle that could ultimately lead to a therapy and, potentially, a longer lifespan for patients suffering from the disease.

Duchenne muscular dystrophy (DMD), predominantly affecting males, is the most common type of muscular dystrophy. Patients with Duchenne muscular dystrophy have a gene mutation that disrupts the production of dystrophin, a protein essential for muscle cell survival and function. Absence of dystrophin starts a chain reaction that eventually leads to muscle cell degeneration and death. While dystrophin is vital for muscle development, the protein also needs several “helpers” to maintain the muscle tissue. One of these “helper” molecular compounds is nNOS, which produces nitric oxide that can keep muscle cells healthy after exercise. (more…)

Close as a Blade-Shaving and Masculinity

Moustaches from the classic handlebar to the dramatic Dali are soon to be cut short as the month of Mo’vember draws to a close, and clean shaven faces return from their period of charitable exile

Research by a historian at the University of Exeter into the history of shaving and masculinity in eighteenth century Britain shows the advancement of new technologies in steel and the connection between advertising are inextricably linked to a closer shave. (more…)

More Potent than Carbon Dioxide, Nitrous Oxide Levels in California May be Nearly Three Times Higher Than Previously Thought

Berkeley Lab researchers devise a new method to estimate state’s greenhouse gas emissions

Using a new method for estimating greenhouse gases that combines atmospheric measurements with model predictions, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found that the level of nitrous oxide, a potent greenhouse gas, in California may be 2.5 to 3 times greater than the current inventory.

The Hobbit: An Unexpected Journey (2012)

Synopsis

Bilbo Baggins, who is swept into an epic quest to reclaim the lost Dwarf Kingdom of Erebor from the fearsome Dragon Smaug. Approached out of the blue by the Wizard Gandalf the Grey, Bilbo finds himself joining a company of 13 Dwarves led by the legendary warrior, Thorin Oakenshield. Their journey will take them into the Wild, through treacherous lands swarming with Goblins, Orcs and deadly Wargs, as well as a mysterious and sinister figure known only as the Necromancer.

Although their goal lies to the East and the wastelands of the Lonely Mountain, first they must escape the Goblin tunnels, where Bilbo meets the creature that will change his life forever…Gollum.

Here, alone with Gollum, on the shores of an underground lake, the unassuming Bilbo Baggins not only discovers depths of ingenuity and courage that surprise even him, he also gains possession of Gollum’s “precious” ring that holds unexpected and useful qualities…A simple, gold ring that is tied to the fate of all Middle-earth in ways Bilbo cannot begin to know.
