Using living cells as nanotechnology factories

October 9, 2008

Arizona State University and New York University researchers are using cells as factories to make DNA-based nanostructures inside a living cell.

They are using a phagemid, a virus-like particle that infects a bacteria cell. Once inside the cell, the phagemid uses the cell just like a photocopier machine. By theoretically starting with just a single phagemid infection, and a single milliliter of cultured cells, they found that the cells… read more

Red-hot growth seen in wireless Internet hotspots

July 11, 2003

The number of worldwide “hotspots” for high-speed wireless Internet is expected to grow to at least 160,000 in 2007 from 28,000 this year, according to market research firm
Allied Business Intelligence.

New Electronic Fiber Heralds Smarter Textiles

July 7, 2010

Capacitor-fibre

A soft, flexible fiber with a 1000 times more capacitance than a coaxial cable could lead to smarter textiles, say its inventors at Huazhong University of Science and Technology in China.

Their idea is to create a simple rolled capacitor from a sheet of conducting polymer sandwiched between two insulating sheets of low density polyethylene. They then roll this sandwich into a cylinder and encase it… read more

Singularity Summit reports

Philips Research Laboratories researchers have found a simple way to make high-performance electronic circuits from organic semiconductors, bringing us one step closer to low-cost, bendable plastic electronics.

They developed self-assembling semiconductor molecules that automatically arrange themselves on a surface in a layer just a few nanometers thick, making hundreds of transistors arranged into complex circuits.

The Atkinson-Phoenix Nanotech Debate

July 21, 2003

William Atkinson wrote a book, Nanocosm, critical of Eric Drexler’s approach to nanotech and of Drexler himself. Chris Phoenix (CRN) wrote a review of the book, critical of Bill’s understanding of the topic. Bill responded. This touched off an email discussion.

Google users promised artificial intelligence

May 26, 2006

A search engine that knows exactly what you are looking for, that can understand the question you are asking even better than you do, and find exactly the right information for you, instantly is a future predicted by Google.

Google co-founder Larry Page said one thing that he had learned since Google launched eight years ago was that technology can change faster than expected.

Google is also looking… read more

Conscientiousness is the secret to a long life (article preview)

October 24, 2008

University of California at Riverside researchers found that people who were less conscientious were 50 per cent more likely to die at any given age, on average, than those of the same age who scored highly.

Panspermia: Spreading Life Through the Universe

July 27, 2003

Researchers have found live cells in samples taken at 41 km above the Earth, suggesting a possible extraterrestrial origin.

New graphene treatment could unleash new uses in electronic devices

MIT team develops simple, inexpensive method that could help realize graphene’s promise for electronics, solar power, and sensors.

A team of researchers at MIT and the University of California at Berkeley has found a simple, inexpensive treatment that may help to unleash graphene’s potential. Currently, many suggested uses of graphene require treatments that can be expensive and difficult to apply predictably.

The new method is described in a paper published in the journal Nature Chemistry, co-authored by MIT doctoral students Priyank Kumar and Neelkanth Bardhan,… read more

Mysterious carbon excess found in infant solar system

June 8, 2006

Astronomers detected unusually high quantities of carbon, the basis of all terrestrial life, in an infant solar system around nearby star Beta Pictoris, 63 light years away.

Mummy, that robot is making faces at me

October 30, 2008

Robotics engineers at the University of Bristol and Hanson Robotics have developed a realistic robot head that can mimic human facial expressions and could make communication more human-like.

Human face movements are picked up by a video camera and mapped onto the tiny servos in the robot’s skin at 25 frames per second (British television frame rate) to produce similarly realistic facial movements.

Modern science map

September 1, 2010

ScienceMapv0.37

Crispian Jago has developed a draft timeline (based on an original London underground map) showing the last 500 years of science, reason and critical thinking “to celebrate the achievements of the scientific method through the age of reason, the enlightenment and modernity.”

Some of the lines are still sketchy, such as the one for Mathematics and Computing. Jago welcomes comments. – Ed

Supercomputing’s New Idea Is Old One

August 4, 2003

Scientists in government, industry and academia involved in the race to build the world’s fastest computing machines are now turning their attention once again to Seymour Cray’s elegant approach to building ultra-fast computers. The designs use special hardware that to handle the long strings of numbers in complex scientific computing problems.

Cray’s revival was helped by funding from the Pentagon’s Defense Advanced Research Projects Agency to develop prototypes of… read more

Record CCD image sensor has 111 million pixels

June 20, 2006

Dalsa Semiconductor has fabricated an image sensor with more than 111 million pixels. The company claims the 4 x 4-inch charge-coupled device, configured as 10,560 x 10,560 pixels, is the world’s highest-resolution image sensor and the first to break the 100 million-pixel barrier.
