Researchers Weidong Huang and Lin Xin from China’s Northwestern Polytechnical University describe their progress with 3D-printed metallic parts, using laser solid forming (LSF) technology, in an open-access (until Nov. 9) review article in 3D Printing and Additive Manufacturing, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

The authors review research advances toward the goal of developing LSF — an additive manufacturing technique that uses laser… read more

Three research groups announced nanotechnology-based targeted drug-delivery systems Wednesday.

Researchers at Cedars-Sinai’s Maxine Dunitz Neurosurgical Institute have used a highly targeted approach to deliver multiple drugs chemically bonded to a transport vehicle. The objective is to bypass healthy cells, accumulate inside tumor cells, and attack molecular targets that enable cancer cells to grow and spread.

The drug transport is in an emerging class called… read more

Advances in Quantum Computing

December 4, 2001

Quantum computing borrows ideas from finance: a balanced portfolio of programs could mean a faster quantum computer.Strategies from the world of finance could help get the best out of quantum computers, say US researchers. The right portfolio of programs could solve a problem many times faster than a single strategem.

Quantum computers – purely hypothetical as yet – would be fast, but you could never be sure whether a… read more

A biped robot design being built by researchers at Oregon State University has the potential to reduce energy use while improving robotic locomotion.

Advances Offer Path to Shrink Computer Chips Again

August 31, 2010

Scientists at Rice University and Hewlett-Packard are reporting this week that they can overcome a fundamental barrier to the continued rapid miniaturization of computer memory by using memristors, or memory resistors, switches that retain information without a source of power.

In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques.

Single-photon emitters release one particle of light, or photon, at a time, as opposed to devices like lasers that release a stream of them.

Single-photon… read more

Advent of the Robotic Monkeys

October 27, 2004

Researchers have trained a monkey to feed itself by guiding a mechanical arm with its mind. It could be a big step forward for prosthetics.

Aerobic exercise boosts brain power in elderly

December 17, 2012

Prefrontal Cortex

Evidence for the importance of physical activity in keeping and potentially improving cognitive function throughout life was found in an open-access literature review in Psychonomic Bulletin & Review by Hayley Guiney and Liana Machado from the University of Otago, New Zealand.

  • Cognitive functions such as task switching, selective attention, and working memory appear to benefit from aerobic exercise. Studies in older adults reviewed

Aerobic exercise grows brain cells

January 21, 2010

Aerobic exercise stimulates the growth of new brain cells and improves the memory and ability to learn, neuroscientists from University of Cambridge and the US National Institute on Aging have found in experiments with mice.

Running mice grew an average of 6,000 new brain cells per cubic millimeter in the dentate gyrus part of the hippocampus.

The researchers speculate that the effect may be due to increased blood… read more

Affordable camera reveals hidden details invisible to the naked eye

Could be added to a future camera for about $50

HyperCam, an affordable “hyperspectral” (sees beyond the visible range) camera technology being developed by the University of Washington and Microsoft Research, may enable consumers of the future to use a cell phone to tell which piece of fruit is perfectly ripe or if a work of art is genuine.

The technology uses both visible and invisible near-infrared light to “see” beneath surfaces and… read more

The team at Formlabs, a MIT Media Lab spinout, has invented a high-resolution 3-D laser printer, called the Form 1, that’s viewed as an affordable option (about $3,300) for professional users.

The desktop printer — standing about a foot high and weighing about 20 pounds — runs on stereolithography, a fabrication technique usually reserved for massive machines that cost hundreds of thousands of dollars.… read more

Africa alone could feed the world

June 29, 2009

There is enough space in the world to produce the extra food needed to feed a growing population. And contrary to expectation, most of it can be grown in Africa, say two international reports published this week.

After 244 Years, Encyclopaedia Britannica stops the presses

March 14, 2012


After 244 years, the Encyclopaedia Britannica is going out of print, New York Times Media Decoder reports.

The last print version is the 32-volume 2010 edition, which weighs 129 pounds, priced at $1,395.

It is survived by a $70/year online edition (free trial here).
