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.
