Terrorists could use internet to launch nuclear attack: report

July 28, 2009

Terrorist groups could soon break into computer systems and set off a devastating nuclear attack, according to a study commissioned by the International Commission on Nuclear Non-proliferation and Disarmament.

Cyber-terrorists could also provoke a nuclear launch by spoofing early warning and identification systems or by degrading communications networks.

Tesco tests spy chip technology

July 21, 2003

Supermarket chain Tesco has admitted testing controversial technology that tracks customers buying certain products through its stores.

RFID tags in razor blades trigger a CCTV camera when a packet is removed from the shelf. A second camera takes a picture at the checkout and security staff then compare the two images, raising the possibility that they could be used to prevent theft.

Tesla plans ‘mostly autonomous’ car within three years

September 20, 2013


Elon Musk has decided that the next step for Tesla Motors cars is to go (mostly) autonomous, IEEE Spectrum reports.

From the Financial Times:
“We should be able to do 90 percent of miles driven within three years,” [Musk] said. Mr Musk would not reveal further details of Tesla’s autonomy project, but said it was “internal development” rather than technology being supplied by another more

Tesla unveils groundbreaking electric car

March 30, 2009

Tesla Motors Chairman and CEO Elon Musk has introduced the new Tesla Model S all-electric sedan, saying the state-of-the-art, five-seat sedan will be the world’s first mass-produced, highway-capable electric car.

The futuristic zero-emission vehicle will be powered by lithium-ion battery packs capable of traveling between 160 and 300 miles per charge.

Test Tube Meat Nears Dinner Table

June 27, 2006

Researchers are developing lab methods of creating edible, lab-grown meat that smells and tastes just like the real thing.

Test tube method analyzes and reconstitutes DNA-repair mechanism

December 15, 2004

One of five known DNA-repair mechanisms in cells has been completely analyzed and reconstituted in a test tube by an international collaboration of researchers led by scientists from the Keck School of Medicine.

The team is the first to reconstitute this pathway, known as the nonhomologous end joining pathway, or NHEJ, and NHEJ is only the third repair pathway to be reconstituted in the laboratory.

After more than a decade of development, Avida’s digital organisms at Michigan State University are now getting close to fulfilling the definition of biological life.

These are digital organisms — strings of commands — akin to computer viruses. Each organism can produce tens of thousands of copies of itself within a matter of minutes. Unlike computer viruses, however, they are made up of digital bits that can mutate and… read more

Testing Drugs with Stem Cells

December 13, 2007

University of Wisconsin-Madison researchers have developed a novel way to test drug toxicity by monitoring the behavior of embryonic stem cells exposed to a drug-candidate compound.

Testing the toxicity of pharmaceutical candidates in lab rats before the compounds are judged safe enough for human clinical trials is notoriously unreliable. Often compounds that appear safe in the rodents prove to be toxic in humans.

Studying how potential drugs affect… read more

Testing for bacteria in minutes instead of weeks

July 2, 2013


EPFL researchers have built a matchbox-sized device that can test for the presence of bacteria in a couple of minutes, instead of up to several weeks.

A nano-lever vibrates in the presence of bacterial activity, while a laser reads the vibration and translates it into an electrical signal that can be easily read: absence of a signal signifies the absence of bacteria.

This makes… read more

Testing Over, to Open Its TV and Film Offerings This Week

March 11, 2008 will make its catalog of TV shows and video clips available to anyone on the Web starting Wednesday.

The streaming-video site displays free, ad-supported shows and feature films from NBC, Fox and more than 50 media companies, including Sony Pictures and Metro-Goldwyn-Mayer.

Testing the Toxicity of Nanomaterials

June 6, 2008

Massachusetts General Hospital researchers and colleagues have developed a high-throughput screening method to test the toxicity of nanomaterials.

A robotic system (similar to that used for drug screening) puts nanoparticles inside tiny wells on a plate containing hundreds of separate wells. Each well contains one cell type. The system detects changes in the cells’ metabolism in response to the nanomaterial.

Testing: A User’s Guide

May 1, 2007

Doctors are developing new tests and guidelines for asthma, bone and cartilage defects, colon cancer, heart disease, obesity, and diabetes.

Tests Begin on Drugs That May Slow Aging

August 20, 2009

Excitement among researchers on aging has picked up in the last few years with the apparent convergence of two lines of inquiry: single gene changes and the caloric-restriction diet.

Tests that show machines closing in on human abilities

January 22, 2009

New ways are being developed to test how well machines can match aspects of human intelligence, including animated human faces, androids, a jazz improvization program, and military robots.

Tethered molecules act as light-driven reversible nanoswitches

(Paul Weiss lab, Penn State)

Penn State University and Rice University scientists have developed a new technique for attaching light-sensitive organic molecules to metal surfaces that allows the molecules to be switched between two different configurations in response to exposure to different wavelengths of light.

This research advance is the first step in designing a device that can be driven or actuated by such molecular change. It could perform useful work as… read more
