20 Years old Satellite debris will fall on Earth : NASA

Around 6.5 ton Research Satellite was carried into orbit by NASA during a space shuttle mission in 1991. It functioned for 14 years, collecting measurements of ozone and other chemicals in the atmosphere.

Satellite has completed its mission in 2005, it has been slowly losing altitude. NASA has reported on its website that the 35-foot-long, 15-foot diameter satellite body is expected to plummet into the atmosphere, NASA reported on its website.

While most of the spacecraft will be burned, scientists expect up to 26 pieces, with a combined mass of about 500kg to continue to exist the fiery re-entry and fall down somewhere on Earth.

The satellite's orbit covers almost all of earth, from as far north as northern Canada to the southern part of South America.

NASA said the chance a piece of satellite debris will strike a person is about one in 3,200. The debris will mostly likely fall into an ocean or land in an uninhabited region of Earth.

Trojan into Android Device | CA Security Release

According to a CA security researcher, new Trojan for Google Android is capable of recording phone conversations. Earlier Trojan found by CA logged the details of incoming and outgoing phone calls and the call duration. But the new Trojan is capable of recording phone conversations in AMR format and stores the recordings on the device's SD card.

The Trojan installs a 'configuration' file that contains information about the remote server and the parameters. It means the recorded calls can be uploaded to a server maintained by an attacker.

Venkatesan, the researcher, tested the Trojan in "a controlled environment with two mobile emulators running along with simulated Internet services,". It appears the Trojan can only be installed if the Android device owner clicks the "install" button on a message that looks strikingly similar to the installation screens of legitimate applications.

Once the Trojan and configuration file gets installed on the device, a phone call activates the trojan that is recording the call and storing it on the SD card.

Android provides more flexibility as compared to other similar devices. But you have to pay for it, in terms of illegitimate application.

Diamonds Aren't Forever : Macquarie University Researchers

Macquarie University Researchers, in a paper published in the US journal Optical Materials Express, show that even the earth's hardest naturally occurring material, the diamond, is not forever.

Associate Professor Richard Mildren and his colleagues from the Macquarie University Photonics Research Centre discovered that diamonds evaporate under exposure to ultraviolet rays.

The diamonds were exposed to intense light pulses in the UV-C band, after a few seconds small pits in the diamond surface were visible. The rate of mass loss in the diamond fell notably for lower light levels but the etching process still continued - although at a slower pace, Mildren said.

Under normal conditions evaporation is very small and not noticeable, so there is no need to panic Mildren said. In fact, even under very bright UV conditions, such as intense sunlight or under a UV tanning lamp, it would take approximately the age of the universe - about 10 billion years - to see an observable distance, he said.

The findings not only provide clues about the long-term stability of diamonds, but also have broad implications for future research.

"It's a very practical discovery and we are now looking at how we can exploit this," Mildren said.

"If we can make structures in the diamonds that enable us to control the position of the light within a very narrow filament in the diamond, that's the first step to making smaller and more efficient optical devices such as those used in quantum computing and high performance lasers."

The discovery may also have implications as far reaching as the prospects for finding diamonds on the surface of other planets, Mildren said.

Good Sleep may well enhance Undergrads' Learning ability

A new study finding reports that the sufficient sleep improves college students' ability to learn.

The study included 102 university undergraduate students who had never taken an economics course and were given an introductory lecture on supply and demand microeconomics. Those tested on the material after they got adequate sleep over a 12-hour period had better scores than those who took the test after being awake for 12 hours.

The findings show that sleep can help college students retain and integrate new information needed to solve problems on an exam.

"Our findings demonstrate the importance of sleep to the ability to flexibly combine distinct concepts to solve novel problems. This ability is critical to classroom learning," lead author Michael Scullin, a doctoral candidate in the Behavior, Brain and Cognition program at Washington University in St. Louis, said in an American Academy of Sleep Medicine news release.
