Washington, August 21 : A team of researchers in the U. S. has come up with the fastest quantum computer bit, which exploits the main advantage of the qubit over the conventional bit.

The team—comprising experts from the University of Michigan, U. S. Naval Research Laboratory, and the University of California at San Diego—has revealed that the use of lasers helped create an initialised quantum state of the solid-state qubit at rates of about a gigahertz, or a billion times per second.

Washington, August 21 : A Purdue University researcher has invented a tiny device called a monolithic comb drive, which may be used as a high-precision "nano-positioner" for such uses as biological sensors and computer hard drives.

Jason Vaughn Clark, an assistant professor of Electrical and Computer Engineering and Mechanical Engineering, insists that the motorized positioning device he has created has twice the dexterity of similar devices being made to boost the performance of biological sensors and computer hard drives.

The researcher says that his design may make it possible to improve a class of probe-based sensors that detect viruses and biological molecules.

Transcend has launched new V95 USB flash drive in the Indian market. The device will prove extremely helpful to people for its elegant data storage capacity.

The new flash drive is very thin with the dimensions of just 40.6 x 18.04 x 7.2 mm. The drive comes in 4GB data storage capacity with ultra thin body.

The chip of newly launched flash drive is constructed on extra-durable COB (Chip On Board). It also supports retractable USB connector. The connector fully supports USB2.0 Plug & Play installation in real time. The drive is provided with cutting edge technology for data management and data storage. The drive is available in two colors namely Onyx Black and Satin Red.

Helsinki - Claims of poor quality welding work at a Finnish nuclear reactor under construction were rejected Wednesday by the Finnish nuclear watchdog.

The Finnish Radiation and Nuclear Safety Authority (STUK) said allegations of "faulty" checks of the welding work being built at Olkiluoto, south-western Finland were "false."

A week ago, environmental group Greenpeace cited "confidential documents" for its call to halt work on the reactor.

Canberra, August 20 : Scientists have suggested that hot rocks technology, also known as geothermal, may provide a possible solution to climate change.

Hot rocks technology works by pumping water deep below the earth’s surface, to areas that generate plenty of heat.

The water converts to steam and shoots back up to the surface, where it is used to make electricity. The technology generates very few greenhouse gas emissions.

According to a report carried out in www. news. com. au, good progress in this field has been made by Australia, which could have its first super-hot power plant within four years.

Washington, August 20 : A team of researchers from the University of Virginia in the US is trying to determine exactly how promising algae biofuel production can be by tweaking the inputs of carbon dioxide and organic matter to increase algae oil yields.

According to a report in ENN (Environmental News Network), algae are tiny biological factories that use photosynthesis to transform carbon dioxide and sunlight into energy so efficiently that they can double their weight several times a day.
