Droid X Users Cautioned About Unofficial Android Update
Motorola cautioned Droid X users Monday to refrain from downloading an unofficial Android 2.2 upgrade circulating around the Internet. Installing the leaked upgrade will prevent Droid X smartphone owners from receiving the final version of the mobile OS slated for release in early September, Motorola warned in a support blog.Motorola's release of Android 2.2 -- also known as Froyo -- will permanently fix some Exchange 2003 e-mail snafus for which Motorola has already been forced to issue temporary workarounds. For example, some Droid X users are currently unable to set up their Microsoft Exchange accounts, while others with e-mail access do not receive any notifications. "Both of these issues will be addressed in the Android 2.2 update," Motorola said.
Enterprise Enhancements Motorola's software upgrade for the Droid X promises to give enterprise customers full push-delivery support for Exchange as well as Gmail for business. Also on tap are live widgets for streaming messages to the user's home screen as well as filter widgets for differentiating work and home e-mails.
Among other things, the Froyo release will sport a corporate directory, a global lookup capability, a unified calendar, and security protocols for remotely setting the device's password for all the documents stored in memory. Additionally, Droid X users will finally be able to permanently delete text messages.
Once Android 2.2 becomes officially available for the Droid X, users will be able to download it over the air, Motorola advised. The software upgrade "will either be pushed to you, or you can grab it by going to Menu > Settings > About phone > System updates," Motorola wrote in a support blog.
The smartphone maker is clearly counting on the Flash Player 10.1 software shipping with Android 2.2 to differentiate the Droid X from rival Apple's popular iPhone, which lacks Flash capabilities....

20:27Federal officials urged U.S. residents to prepare for possible evacuations and islanders in the Turks and Caicos hunkered down in their homes Tuesday as powerful Hurricane Earl howled over open seas toward the East Coast of the U.S.
The Category 4 hurricane, with winds of 135 mph (215 kilometers), was expected to remain over the open ocean before turning north and running parallel to the U.S. coast, potentially reaching the North Carolina coastal region by late Thursday or early Friday. It was projected then to curve back out to sea, perhaps swiping New England or far-eastern Canada.
"We can't totally rule out a very close approach to either of the Cape Hatteras areas or Cape Cod and southern New England as the storm progresses further," said Bill Read, director of the U.S. National Hurricane Center in Miami.
Earl delivered a glancing blow to several small Caribbean islands Monday, tearing roofs off of homes and cutting electricity to people in Anguilla, Antigua, and St. Maarten. Cruise ships were diverted and flights canceled across the region. But there were no reports of death or injury.
Gusty winds from Earl's outer fringes were whipping palm fronds and whistling through doors as Turks and Caicos Islands residents hunkered down in their homes and tied-down boats seesawed on white-crested surf.
A small crowd of islanders gathered early Tuesday afternoon to watch big waves pound a Grand Turk shore, as the wind sent sand and salt spray flying.
"We can hear the waves crashing against the reef really seriously. Anybody who hasn't secured their boats by now is going to regret it," Kirk Graff, owner of the Captain Kirks Flamingo Cove Marina, said by phone as he watched the darkening skies.
In Providenciales, Benson Capron was among several fishermen tying their boats to trees lining the beach.
"I hear it is going to pass,...

20:27Around 70 million years ago a stocky dragon stalked what is now Romania.
A new type of dinosaur similar to the frightening Velociraptor -- but with two sharp claws on each foot instead of just one -- has been discovered by Romanian and American researchers.
"Balaur bondoc," which means "stocky dragon," was discovered in Romania by geologist Matyas Vremir of the Transylvanian Museum Society. The find is reported in Tuesday's edition of Proceedings of the National Academy of Science.
"Balaur might be one of the largest predators in this ecosystem," explained co-author Zoltan Csiki of the University of Bucharest, who noted that higher sea level at the time made the region an island archipelago.
Csiki said that while Balaur is extremely unusual, it is closely related to animals like Velociraptor and the feathered dinosaurs in China.
The researchers said the fossils show an animal 6 to 7 feet long with a stockier build than similarly sized Velociraptors that lived elsewhere on the globe. There are numerous similarities between the two predators, though.
"While we would expect that there were carnivorous animals in these faunas, finding one as unusual as Balaur is thrilling," said co-author Mark Norell of the American Museum of Natural History in New York.
Matthew T. Carrano, curator of dinosauria at the Smithsonian's National Museum of Natural History in Washington, said the discovery is "one of those bizarre things that keeps reminding us not to expect that we've found everything there is to find." Carrano was not part of the research team.
In the same region researchers have also uncovered fossils of tiny duckbilled dinosaurs and dwarf plant-eating dinosaurs that were the size of cows.
The new Balaur fossil is a partial skeleton that includes leg, hip, backbone, arms, hand, rib, and tail bones.
It had a big toe with a large claw that can be hyperextended, presumably...

20:27Scientists reviewing the acclaimed but beleaguered international climate change panel called Monday for a major overhaul in the way it's run, but stopped short of calling for the ouster of the current leader.
The independent review of the U.N. climate panel puts new pressure on chairman Rajendra Pachauri, who has been criticized for possible conflicts of interest, but shows no sign of stepping down.
"It's hard to see how the United Nations can both follow the advice of this committee and keep Rajendra Pachauri on board as head," said Roger Pielke Jr., a frequent critic of the Intergovernmental Panel on Climate Change. The University of Colorado professor praised the review findings as a way of saving the climate panel with "tough love."
The InterAcademy Council, a collection of the world's science academies, outlined a series of "significant reforms" in management structure needed by the IPCC, a body that won a Nobel Prize with former Vice President Al Gore in 2007.
Last year, a batch of errors embarrassed the authors of the climate report. Among the most prominent were misleading statements about glaciers in the Himalayas. The IPCC incorrectly said they were melting faster than others and that they would disappear by 2035 -- hundreds of years earlier than other information suggests.
"Those errors did dent the credibility of the process, no question about it," said former Princeton University president Harold Shapiro, who led the review of the IPCC.
Climate change science took a parade of public hits last winter, starting with the release of hacked e-mails from a British climate center. Then there was the failure of a summit in Copenhagen to come up with mandatory greenhouse gas pollution limits, followed by the mistakes discovered in the IPCC report. On top of that, the winter seemed unusually cold in many places, undercutting belief in global warming.

20:27Experimental unmanned rockets being developed by California and Texas firms will make test flights to the edge of space this fall and winter under a NASA funding plan announced Monday.
Masten Space Systems of Mojave, California, and Armadillo Aerospace of Rockwall, Texas, were awarded a total of $475,000 by NASA's Commercial Reusable Suborbital Research Program, the space agency said.
The two companies are among an elite group of private spaceflight entrepreneurs that are not as well-known as the marquee programs being developed for Sir Richard Branson's Virgin Galactic space tourism company at Mojave, and SpaceX, the Hawthorne, California, company seeking to become NASA's choice for space station supply missions.
NASA wants the flights to demonstrate capabilities of the Masten and Armadillo vehicles to carry small payloads to what it terms "near-space" -- altitudes between 65,000 feet (20,000 meters) and 350,000 feet (106,000 meters).
The program is seeking dependable rocket systems that can fly at reasonable cost while safely returning payloads to the ground.
Masten's president and chief executive officer, David Masten, said he hopes the contract is a bellwether of a long association with NASA.
"This means we've got a nice wonderful start," he said.
Masten will use a modified version of a vertical-takeoff-and-landing rocket it used last year to win a $1 million contest as it attempts to simulate a lunar landing by taking off from a pad, flying horizontally to land on another pad then taking off again to return to the starting point.
Masten's craft will make two flights late this year and two early next year from Mojave Air & Spaceport in the high desert north of Los Angeles. Two are planned to reach altitudes about three miles high and two will go to about 18 miles (29 kilometers) high, NASA said.
The latter flights will lift off slowly and then go to full throttle,...

20:27It's flu-shot season already, and for the first time health authorities are urging nearly everyone to get vaccinated. There is even a new high-dose version for people 65 or older.
What a difference a year makes: Crowds lined up for hours for scarce shots during last fall's swine flu pandemic, when infections peaked well before enough vaccine could be produced. This year, a record vaccine supply is expected -- an all-in-one inoculation that now promises protection against that swine flu strain plus two other kinds of influenza.
Shipments began so early that drugstores are offering vaccinations amid their back-to-school sales.
But without last year's scare factor, the question is how many people will heed the new policy for near-universal vaccination. No more stopping to check if you're on a high-risk list: A yearly dose is recommended for virtually everyone except babies younger than 6 months -- the shot isn't approved for tots that young -- and people with severe allergies to the eggs used to brew it.
"Influenza is serious, and anyone, including healthy people, can get the flu and spread the flu," said Dr. Anne Schuchat of the Centers for Disease Control and Prevention. "Flu vaccines are the best way to protect yourself and those around you."
The CDC was moving toward that policy even before last year's pandemic brought home an inescapable fact: The flu virus doesn't just kill grandparents and babies and people with weak lungs or hearts, although they're particularly vulnerable. It also can kill healthy pregnant women and 30-somethings. And 5-year-olds.
"We were discussing how we were going to go get his Star Wars Halloween costume after he got out of the hospital ... and all of a sudden his eyes lost their focus," said Serese Marotta of Dayton, Ohio, describing for reporters how her son Joseph, 5, died of swine...
