Melbourne, Oct 8 : In a remarkable discovery, scientists have for the first time unravelled bacteria''s stress buster— a "co-ordination centre” that directs a bacteria''s defence systems to fight off external threats and stresses.

The team of British and Australian researchers has shown how the centre alerts the bacteria to danger and prompts it to create proteins to negate the threat, reports ABC Online.

Washington, October 8 : Rice University in Houston is running an advanced computer security course wherein students are taught just how easy it is to wreak havoc on the computer software used in electronic voting machines.

Associate Professor Dan Wallach, Director of Rice''s Computer Security Lab, tests his students in a unique real-life experiment as part of his advanced computer science class—instructing them to do their very best to rig a voting machine in the classroom.

In the first phase, the teams pretend to be unscrupulous programmers at a voting machine company. Their task would be to make subtle changes to the machine’s software that can alter the election’s outcome without being detected by election officials.

Washington, Oct 8 : Researchers have captured on camera the deepest fish caught alive ever, the ghostly snailfish, at the depth of 4.8 miles (7.7 kilometers) beneath the surface of the Pacific Ocean.

According to a report in National Geographic News, the record-breaking video was shot in the Japan Trench by researchers who used dead mackerel to lure the abyssal creatures toward waiting cameras.

The researchers in the US have created see-through (transparent) solar cells that can be used as windows on cars or buildings, even as they generate electricity. 

Solar cell technology, which earlier used to be really light weight was not efficient enough to covert large amount of Sun’s energy into electricity. 

Nevertheless, a technique was discovered through the study led by scientist John Rogers of the University of Illinois, under which super thin cells were created that, delivered excellent efficiency. 

Washington, Oct 8 : A research team in Denmark has found new data about thermoelectric materials that can be used to develop motors that are more fuel-efficient and for more environmentally friendly cooling methods in the future.

Researchers at the University of Arhus, Riso-DTU and the University of Copenhagen, in Denmark, found the data.

Thermoelectric materials can be assembled into units, which can transform the thermal difference to electrical energy or vice versa - electrical current to cooling.

An effective utilization requires however that the material supplies a high voltage and has good electrical, but low thermal conductivity.
