Heading for regeneration: Researchers reactivate head regeneration in regeneration-deficient species of planarians
[unable to retrieve full-text content]Rabbits can't do it, neither can frogs, but zebrafish and axolotls can and flatworms are true masters of the craft: regeneration. Why some animals can re-grow lost body parts or organs while others cannot remains a big mystery. And even more intriguing to us regeneration-challenged humans is the question whether one might be able to activate regenerative abilities in species that don't usually regenerate.

FDA: Menthol cigarettes likely pose health risk
RICHMOND, Va. (AP) ? A Food and Drug Administration review concludes that menthol cigarettes likely pose a greater public health risk than regular cigarettes but does not make a recommendation on whether to limit or ban the minty smokes ? one of the few growth sectors of the shrinking cigarette business.
The federal agency released the independent review on Tuesday and is seeking input from the health community, the tobacco industry and others on possible restrictions on the mint-flavored cigarettes.
The FDA evaluation concluded that there is little evidence to suggest that menthol cigarettes are more or less toxic or contribute to more disease risk to smokers than regular cigarettes. However, there is adequate data to suggest that menthol use is likely associated with increased smoking initiation by younger people and that menthol smokers have a harder time quitting, the review said.
There's also evidence indicating that menthol's cooling properties can reduce the harshness of cigarette smoke and that menthol cigarettes are marketed as a smoother alternative, the review said.
"Menthol cigarettes raise critical public health questions," Mitch Zeller, director of the Center for Tobacco Products, said in a conference call with reporters.
Zeller said there's "no holdup" on the FDA proposing restrictions on menthol but that there are still "some important questions" that need to be answered. The agency is commissioning further research.
A 2011 FDA advisory panel report, which was mandated under the 2009 law giving the agency the authority to regulate tobacco, made many of the same findings, and said that removing menthol cigarettes from the market would benefit public health and highlighted greater use among minorities, teenagers and low-income people. Panels like the tobacco committee advise the FDA on scientific issues. The agency doesn't have to follow its recommendations, but often does.
Meanwhile, a tobacco industry report to the FDA acknowledged that all cigarettes are hazardous but said there's no scientific basis for regulating menthols differently. The industry also has raised concerns that restrictions on menthol would lead to a black market for the cigarettes.
Menthol cigarettes are one of the few growth areas in a shrinking cigarette market. The percentage of U.S. cigarette smokers using menthol brands grew from 33.9 percent in 2008 to 37.5 percent in 2011, according to a study by the federal Substance Abuse and Mental Health Services Administration, with more significant growth among younger smokers.
A menthol ban or other restriction on the flavored cigarettes would fall heavily on Lorillard Inc., whose Newport brand is the top-selling menthol cigarette in the U.S., with nearly 38 percent of the market. Lorillard, based in Greensboro, N.C., is the country's third-largest tobacco company.
CEO Murray Kessler said in a statement Lorillard looks forward to participating in the regulatory process and reiterated its long-held belief that menthol cigarettes shouldn't be treated differently.
The move comes ahead of a Wednesday deadline for the U.S. to respond to the World Trade Organization's findings last year that the FDA's ban on manufacturing, importing, marketing and distributing candy-, fruit- and clove-flavored tobacco breaks trade rules because it exempts menthol cigarettes, most of which are made in the U.S.. The investigation was launched following a request from Indonesia, which claims more than 6 million of its people depend on the production of clove cigarettes ? a staple of the country's smoking culture.

DingDong! Here's The New Craze In Photo Messaging Apps And It's Addictive
Lately I've been playing with a great little app called Povio. Not unlike Snapchat, you snap a picture and send to one or more people and the app prompts them to send one back, though the photo doesn't disappear. It's a little like photo messaging "with a nudge." However, another player has been coming up with its own take on this idea, and today we can exclusively give some of you lucky people access to the DingDong app, which is one of the most viral we've seen lately.Source: http://feedproxy.google.com/~r/Techcrunch/~3/re5CNiOlfOM/

'Justice League' And 'Flash' Movies Rumored - Business Insider
Warner Bros.
It's DC vs. Marvel at the movies.As Warner Bros. prepares to go to battle with Disney at theaters in 2015 with the newly announced Batman/Superman movie, The Hollywood Reporter says WB?is also planning a "Flash" film and "Justice League" movie.
THR reports sources revealed plans for a?"Flash" adaptation set for 2016 and a "Justice League" film for 2017.
Throughout DC history, there have been a few different members of the Justice League at any given time.?
The original members include?Superman, Batman,?the Martian Manhunter, Green Lantern, Wonder Woman, Aquaman, and the Flash.
Other versions have included Hawkgirl/man, Black Canary, Green Arrow, Atom, and Zatanna.
The popular WB animated series included seven members with Flash and Wonder Woman.
At Comic-Con CW "Arrow" actor?Stephen Arnell has said he'd love to be in a "Justice League" adaptation.
"I think that Green Arrow has an opportunity to mature in much the same way Iron Man did in the Marvel universe," Arnell told SciFiNow.
"It's always up to what's popular at the moment," he added. "Right now archery seems to be having a mini renaissance, so hopefully he can settle into a firm rotating member of the DC?Justice League of America."

'Enough is enough,' Mayor Hales cracks down on homeless protesters
kgw.com
Posted on July 20, 2013 at 4:11 PM
Updated today at 5:13 PM
PORTLAND -- The eviction notices went up late Friday night telling camping protesters they must leave the sidewalks around City Hall, but the notices were ripped down by protesters faster than they went up.?
"If they raid us, we will raid them because there are a lot more kids that are crazier than cops think," said a young homeless protester who goes by Angel.?
"I decided to handcuff myself to this tree due to the fact that I believe in my First Amendment rights to protest," said Trevor Matney who has lived in front of City Hall for six months now.
Alvin Ronald Taylor is a pastor at the Union Gospel Mission.? He's concerned about the city's new plan to evict the homeless from City Hall.?
"It creates a domino effect and what happens is when people have no where to go, they're out on the street and the next step is crime," he said.
Dana Haynes with the Mayor's office said crime is what's behind the Mayor's move to evict.
"When police showed Mayor Hales there had been 113 calls to the block around City Hall over the past 180 days, Mayor Hales said enough is enough," said Haynes.?
He said the city changed the zoning around City Hall to a high-use pedestrian zone which they said makes it illegal to camp.
"Portland is in a dilemma," said homeless veteran Dwayne Owen, who first learned about Portland after his wife died of a stroke in Indiana and his alcohol abuse sent him to a homeless shelter in Indiana.? "I was told if you're going to be homeless then Portland, Oregon is the best place in the U.S. to be homeless."
Portland's reputation as a caring place could be seen at an annual downtown compassion event at the Veteran's Memorial Coliseum Saturday.? More than 400 volunteers provided food, health care, dental care, even haircuts to those in need.? More than 1,000 people were served in just a few hours.
Portland is performing a tough juggling act: In the air, compassion, the right to protest and public safety.? Which ball will fall first?
"None of us are leaving this sidewalk outside City Hall," said a young homeless protester.

Sony Xperia Z Ultra?s handwriting recognition tested with coin, pen and knife
The Sony Xperia Z Ultra was announced last month as the company?s first foray into the realm of phablets with its robust 6.5-inch screen.
Besides the new Triluminous display engine, the Z Ultra features Sony?s handwriting recognition technology, which lets you write on the display using nearly anything with tip less than 1mm in diameter. This latest video takes a closer look at exactly what does and doesn?t work as a writing device ? from a set of keys to Stanley knives.
Most things worked fairly well, and it?s good to see that the key worked very well, especially since it?s one thing you?ll most likely have on hand in a pinch. Oddly enough, the mechanical pencil didn?t register at all, neither did the plastic ruler, and that goes without saying for the Stanley knife ? although we recommend you don?t use the latter even if it did work. Good news is, even if many of these didn?t make for great stylus alternatives, they didn?t damage the display either, which means the Xperia Z Ultra certainly won?t be an easy to scratch device.
Either way, you?ll be able to try all of these and more soon enough, as the Xperia Z Ultra is set to hit Europe in September and Asia this month.
Thanks, gmfady, for the tip!

Smile! Cassini sets up shot of Earth
19 July 2013
Last updated at 05:43 ET
The world is being asked to look up on Friday and smile in the direction of the ringed planet, Saturn.
The Cassini probe, in orbit around the gas giant, is going to take a picture of Earth, and the imaging team wants everyone to wave and smile.
Because of the great distance to Saturn, our home will appear as a mere pixel in the final photo.
But Cassini scientist Carolyn Porco says it is a moment to "celebrate life on the Pale Blue Dot".
"Waving time" - the period when the spacecraft's cameras will be operating - starts at 21:27 GMT and ends at 21:42 GMT (22:27-22:42 BST).
These timings include the 80 minutes it will take reflected light from the surface of the Earth to travel the nearly 1.5 billion km (900 million miles) to reach the outer Solar System.
Dr Porco's Ciclops imaging team will be producing a large mosaic of Saturn and its ring system on Friday.
Earth will appear as small speck in the lower-right of the final picture.
It is likely to be several days before the first images are processed and released.
The probe snapped a similar mosaic in 2006. On that occasion, Earth was positioned in the upper-left of the frame.
But Dr Porco says the set-up six years ago was not ideal. For the re-shoot, she plans to use Cassini's highest resolution camera, and the most appropriate filters to capture Earth in natural colour.
More than that, however, she says, people on Earth will know this time they are on camera, and that offers everyone the opportunity to participate.
Dr Porco hopes the picture will be reminiscent of the famous "Pale Blue Dot" image captured by the Voyager-1 probe in 1990.
That was a picture she helped organise with the astronomer and popular science writer Carl Sagan.
He memorably described the Earth as looking like a "mote of dust suspended in a sunbeam", such was its apparent insignificance in the vastness of space.
Inspired in part by the Cassini team's plans, scientists working on the Messenger probe at Mercury will also be picturing Earth on Friday and Saturday.
Messenger will see Earth as it scans the skies for any previously unrecognised objects that might be circling the innermost world.
Timings for these pictures are 11:49, 12:38, and 13:41 (all GMT) on both Friday and Saturday.
Parts of the Earth not illuminated in the Cassini images, including all of Europe, the Middle East and Central Asia, will appear illuminated in the Messenger pictures.
More details on the Saturn project can be found at The Day The Earth Smiled website.
