Are they really that Smart?

TORONTO – Has your phone been unexpectedly slow or turned off altogether during the prolonged period of cold weather recently? Well, that may be because of the battery and the screen.

Joe Tersigni, managing partner of Cell Phone Repair, said the lithium ion battery and the LCD display simply don’t work well in cold temperatures.

“The [battery] material was made out of lithium and in extreme temperatures, hot or cold, there are changes in the chemical. It’s a chemical reaction. So the battery will work harder trying to retain the temperature of the phone,” he said.

When the battery becomes too cold, the phone may turn off. While the natural reaction may be to immediately hit the power button and try to turn the phone back on, Tersigni warns that is a terrible idea.

Debate unresolved on protecting Great Lakes from Asian carp

worth while.

Global News

TRAVERSE CITY, Mich. – The debate over how to protect the Great Lakes from voracious Asian carp appeared no closer to settlement Tuesday following release of a federal report with options that could cost billions and require extensive re-engineering of Chicago’s busy waterway network.

Wrapping up a study that began in 2009, the U.S. Army Corps of Engineers put forward eight options for preventing the carp and other invasive species from slipping between the Great Lakes and Mississippi River watersheds. The choices range from doing nothing new to undertaking massive construction projects to separate the two systems.

Director of National Intelligence James Clapper met Tuesday with the five-member panel of intelligence and legal experts tapped by President Barack Obama. The group developed 46 tough oversight recommendations and Obama is weighing which to implement.

Among the proposals discussed in Tuesday’s meetings was ending the NSA’s massive collection of telephone data. Instead, phone companies or a third party could store the data.

Clapper’s office says the group also discussed the NSA’s weakening of commercially-used secure encryption standards. Another topic was a proposal to require greater judicial oversight for so-called national security letters that authorities use to seize financial and phone records.

AAS Meeting Highlights Several New Hubble Science Findings

NASA’s Hubble Space Telescope is providing a new perspective on the remote universe, including new views of young and distant galaxies bursting with stars. Scientists described the findings Tuesday in a news conference sponsored by the American Astronomical Society (AAS).

Highlighted in the briefing were three discoveries — four unusually bright galaxies as they appeared 13 billion years ago, the deepest image ever obtained of a galaxy cluster, and a sampling of galaxies thought to be responsible for most of the stars we see today.

The ultra-bright, young galaxies, discovered using data from NASA’s Hubble and Spitzer space telescopes, are bursting with star formation activity, which accounts for their brilliance. The brightest one is forming stars approximately 50 times faster than our Milky Way galaxy does today. These fledgling galaxies are only…
