Nanoimaging in 3-D

December 2, 2009

(Alexander Govyadinov)

A new nondestructive near-field method for subwavelength optical imaging of nanoscale objects in three dimensions has been demonstrated by University of Pennsylvania scientists.

Piecing Together The Next Generation Of Cognitive Robots

May 7, 2008

The European Cognitive Systems for Cognitive Assistants artificial cognitive systems (CoSy ACS) project incorporates a range of technologies, including a design for cognitive architecture, spatial cognition, human-robot interaction and situated dialogue processing, and developmental models of visual processing.

It integrates multiple cognitive functions to create robots that are more self-aware, understand their environment and can better interact with humans.

A Dose Of Genius

June 12, 2006

The use of “smart pills” that increase concentration, focus, wakefulness and short-term memory is soaring.

Nanolitho effort harnesses self-assembly

August 6, 2003

Nanoscale patterning of silicon substrates with regular, repeatable, atomically perfect application-specific templates could enable manufacturable nanoscale chips within the decade, according to scientists at the University of Wisconsin’s Materials Research Science and Engineering Center (Madison).

The technique can achieve dimensions of tens of nanometers and could someday result in a computer with 4,000 Gbytes of memory. The team used block co-polymers that “self-assemble like snowflakes,” according to their report,… read more

Boom! Hok! A Monkey Language Is Deciphered

December 8, 2009

The Campbell’s monkey of Tai Forest, Ivory Coast appear to exhibit the most complex example of “proto-syntax” in animal communication known to date, say researchers writing in The Proceedings of the National Academy of Sciences.

The monkeys can both vary the meaning of specific calls by adding suffixes and combine calls to generate a different meaning.

Closer encounter: Nasa plans landing on 40m-wide asteroid travelling at 28,000mph

May 9, 2008

NASA plans to use Orion, the Space Shuttle replacement, for a three to six month round-trip to an asteroid, with astronauts spending a week or two on the rock’s surface.

The mission will give space officials a taste of more complex missions, and samples taken from the rock could help scientists understand more about the birth of the solar system and how best to defend against asteroids that veer… read more

Online’s range getting wider and deeper as Stanford’s course offerings take advantage of new technology

March 26, 2013

Stanford_University_campus_from_above

Around 20 Stanford courses will be taught entirely or partially online this spring.

Some courses have been taught before, others are brand new; some are entirely for public consumption, while others are reserved for on-campus students.

The offerings have expanded beyond computer science and engineering to political science, the humanities, and public health, among many other fields.

Reading ‘to go’ for blind people

June 22, 2006

The K-NFB, the latest product to be developed by inventor Ray Kurzweil, is a portable scanning device that reads text to visually impaired people.

It will help with ad-hoc reading of documents such as bills and receipts, instructions on food packaging or medication or emergency evacuation notices in hotels.

Ray Kurzweil is also inventor of the first print-to-speech reading machine for the blind and other landmark… read more

Nanoprobes hit targets in tumors, could lessen chemo side effects

December 15, 2009

The number and distribution of nanoprobes coated with the breast cancer drug Herceptin and inserted into live human tumor cells in the lab have been measured by Purdue University researchers.

Targeting only tumor cells with nanoprobes would require less drugs and mitigate the side effects of cancer chemotherapy drugs, they suggest. Cancer treatments often use high drug concentrations that damage healthy cells near a tumor.

Hydrogen Fuel from Formic Acid

May 15, 2008

New research at the Leibniz Institute of Catalysis (Germany) shows that formic acid could be used as a safe, easy-to-transport source of hydrogen for fuel cells–initially to power portable electronic devices, such as cell phones and laptops.

Top computer hangs on to its title

July 3, 2006

IBM’s BlueGene/L computer at Lawrence Livermore National Laboratory (LLNL) in California, has once again been crowned world champion by the TOP500 list of the fastest supercomputers used for scientific applications, with a computing speed of 280.6 terraflops per second.

Horst Simon, associate laboratory director at Lawrence Berkeley National Laboratory and a member of the TOP500 team, said the next TOP500 champ would be a big jump to 500 or… read more

Plastic Electronics

August 25, 2003

Plastic chips could rival silicon sometime in the 2010s for wall-size television displays to ultra-tiny transistors. The potential has captivated some heavyweight companies in computers and consumer electronics.

Scientists improve chip memory by stacking cells

December 22, 2009

Scientists at Arizona State University have developed a way to create inexpensive, high-density data storage by stacking memory layers inside a single chip.

Vitamin D May Help Curb Breast Cancer

May 20, 2008

Mount Sinai Hospital (Toronto) researchers found that women with insufficient vitamin D were nearly twice as likely to have their cancer recur or spread over the next 10 years, and 73 percent more likely to die of the disease.

In another study, University of California San Diego researchers found an association between sun exposure and lowered breast cancer rates. (Ultraviolet B radiation in sunlight triggers production… read more

A ‘light switch’ in the brain illuminates neural wiring

In a vivid example of how neuroscientists are meticulously tracing the microwiring of the brain, Norwegian researchers have used an optogenetic light switch to see (literally) which neurons communicate with each other in one small section of the brain.

The researchers at the Norwegian University of Science and Technology (NTNU)’s Kavli Institute of Systems Neuroscience use a virus that acts as a… read more
