First All-Nanowire Sensor

August 13, 2008

Researchers at the University of California, Berkeley, have created the first integrated circuit that uses nanowires as both sensors and electronic components.

With a simple printing technique, the group was able to fabricate large arrays of uniform circuits, which could serve as image sensors.

The printing method could also allow nanowires to be printed onto paper or plastics.

Use the force, bacteria

January 7, 2007

A newly discovered bacterium that infests the mitochondria of tick ova has been named Midichloria mitochondrii, in honor of George Lucas’ invention for his Star Wars movies.

According to Lucas, the mysterious intracellular organisms apparently reside within the cells of almost all living things and communicate with the Force.

Probing the brain’s mysteries

January 25, 2012


Researchers at the Human Connectome Project, the Allen Institute for Brain Science in Seattle and other centers are beginning to chart the brain’s major circuits.

The Human Connectome Project is a five-year, $40 million effort funded by the National Institutes of Health. Researchers at 11 institutions are mapping the largest conduits among brain regions by combining four imaging techniques, including a new method called diffusion magnetic-resonance imaging that allows… read more

New Data on 2 Doomsday Ideas, Big Rip vs. Big Crunch

February 23, 2004

A dark unseen energy is steadily pushing the universe apart, just as Einstein predicted, suggesting the universe may have a more peaceful end than recent theories envision, according to striking new measurements of distant exploding stars by the orbiting Hubble Space Telescope.

Three-Dimensional Cell Culture

April 26, 2010

A new technique that uses magnetic nanobeads to levitate cells, allowing them to grow on an “invisible scaffold” into three-dimensional structures, results in cell cultures that tend to form tissues that more closely resemble those inside the body.

The technique could save millions of dollars in drug-testing costs.

Virus helps to build tiny battery

August 19, 2008
(Nam et al/PNAS)

MIT scientists have designed a quick method to build a microbattery using a genetically engineered virus called M13, the first time a battery device has been stamped.

Each virus is a semi-rigid fiber a few nanometers in diameter and about a micron long, which tends to pack tightly into a whorl that looks similar to a fingerprint.

The device could be used to power microdevices for… read more

Robo-builder threatens the brickie

January 17, 2007

Engineers are developing the worlds first robots capable of building a complete house.

One method, inspired by the inkjet printer, involves computer-controlled robotic nozzles which pipe quick-drying liquid gypsum and concrete to form walls, floors and roofs, building the shell of the house in 24 hours.

“This is a harbinger of how we will eventually build large objects (like buildings) from modules constructed by nanoassemblers,” comments Ray Kurzweil.

Canyon or Mirage?

March 5, 2004

The difference in availability of information and communication technologies (between rich and poorer countries, known as the “digital divide,” has concerned policymakers, academics, and non-governmental organizations. But two economists at the World Bank have found that current trends suggest the divide is actually shrinking, not growing.

One in eight to cut cable and satellite TV in 2010

May 3, 2010

Yankee Group has uncovered a new category of consumer: the coax-cutter — those who cut off their pay TV services and use their PCs, gaming consoles and other connected devices to access video programming instead.

One in 8 consumers are set to join their ranks in the next 12 months.

Other findings include:

* Pay TV market is flat-lining. Subscribers in Western Europe will increase just… read more

Fish Tale Has DNA Hook: Students Find Bad Labels

August 25, 2008

Two teenagers checked 60 samples of seafood in restaurants using a simplified genetic fingerprinting technique to see whether the fish New Yorkers buy is what they think they are getting. They weren’t.

Although the testing technique is at the forefront of research, the fact that anyone can take advantage of it by sending samples off to a laboratory meant the kind of investigative tools once restricted to Ph.D.’s and… read more

Touch Screens for Many Fingers

January 24, 2007

Researchers have bigger plans for multi-touch screens than the novel interface on Apple’s iPhone.

Jeff Han, consulting research scientist at New York University, has developed an inexpensive way to make large multi-touch screens accommodating 10, 20, or even more fingers. He envisions applications ranging from interactive whiteboards to touch-screen tables and digital walls–any of which could be manipulated by more than just one person.

Some researchers are even… read more

Half of Fortune 500s, US govt. still infected with DNSChanger trojan

February 6, 2012


More than two months after authorities shut down a massive Internet traffic hijacking scheme, the malicious software that powered the criminal network is still running on computers at half of the Fortune 500 companies, and on PCs at nearly 50 percent of all federal government agencies, new research shows, Krebs on Security reports.

The malware, known as the “DNSChanger Trojan,” quietly alters the host computer’s Internet settings… read more

Robo-talk Helps Pocket Translator

March 16, 2004

Papero (Partner-Type Personal Robot), the first all-hearing, all-seeing robot, is able to translate verbally between two languages in colloquial tongue.

Engineered Metamaterials Could Recreate the Birth of Extra-Dimensional Universes in the Lab

May 11, 2010

Using metamaterials, physicist Igor Smolyaninov at the University of Maryland in College Park thinks we can create analogies for some of the most interesting cosmological occurences like multiverses and even the birth of universes.

In the same way gravity bends light, metamaterials can bend electrical and magnetic fields to create a metamaterial version of relativity. We can, he says, create metamaterials with electromagnetic spaces that possess compactified dimensions.… read more

‘Space Cube’ could be world’s smallest PC

August 29, 2008

Shimafuji Corporation has developed the Space Cube, a 2×2 inches PC designed for use in space to control various electronics and manage an “interstellar computer network.”

Running on just 5 Watts, the PC has a 300 MHz CPU, 16 MB of on-board flash memory, 64MB SDRAM card, LAN port, USB port, Ethernet port, and VGA monitor connector.
