Perry, filibuster star clash over Texas abortions
DALLAS (AP) ? A battle over proposed abortion restrictions in Texas became a personal grudge match Thursday between conservative Republican Gov. Rick Perry and a Democratic state senator whose lengthy, one-woman filibuster catapulted her to sudden, national political stardom.
During a speech to the National Right to Life Conference, Perry singled out state Sen. Wendy Davis of Fort Worth, saying that her life story proves all children born into difficult circumstances deserve not be aborted.
"She was the daughter of a single woman, she was a teenage mother herself. She managed to eventually graduate from Harvard Law School and serve in the Texas Senate," Perry said. "It's just unfortunate that she hasn't learned from her own example that every life must be given a chance to realize its full potential and that every life matters."
In comments to reporters afterward, he went even further, saying that he was glad Davis' mother didn't chose to have an abortion.
"What if her mom had said, 'I just can't do this. I don't want to do this,'" Perry said. "At that particular point in time I think it becomes very personal."
Davis shot back in an email statement after Perry's speech: "Rick Perry's statement is without dignity and tarnishes the high office he holds."
"They are small words that reflect a dark and negative point of view," she said. "Our governor should reflect our Texas values. Sadly, Gov. Perry fails that test."
Davis starting working at 14 to help support a household of her single mother and three siblings. By 19, she was already married and divorced with a child of her own ? but she eventually graduated with honors from Harvard Law School and won her senate seat in an upset.
On Tuesday, Davis' marathon speech and raucous outbursts from abortion rights protesters in the state Senate that kept lawmakers from approving sweeping restrictions that could make abortion all but impossible for many women in the second-largest state.
Those efforts ran out the clock on the midnight deadline Tuesday to pass legislation during a special legislative session Perry called to tackle abortion and other key issues. But on Wednesday, he called a second, 30-day extra session and put tighter abortion rules at the top of the agenda he sets for lawmakers.
The extra session has delayed Perry's expected announcement on whether he will seek a fourth full term as governor in elections next year. Davis is up for re-election then too, but some Democratic activists are urging her to seek the party's gubernatorial nomination.

Scientists discover thriving colonies of microbes in ocean 'plastisphere'
June 27, 2013 ? Scientists have discovered a diverse multitude of microbes colonizing and thriving on flecks of plastic that have polluted the oceans -- a vast new human-made flotilla of microbial communities that they have dubbed the "plastisphere."
In a study recently published online in Environmental Science & Technology, the scientists say the plastisphere represents a novel ecological habitat in the ocean and raises a host of questions: How will it change environmental conditions for marine microbes, favoring some that compete with others? How will it change the overall ocean ecosystem and affect larger organisms? How will it change where microbes, including pathogens, will be transported in the ocean?
The collaborative team of scientists -- Erik Zettler from Sea Education Association (SEA), Tracy Mincer from Woods Hole Oceanographic Institution (WHOI), and Linda Amaral-Zettler from the Marine Biological Laboratory (MBL), all in Woods Hole, Mass. -- analyzed marine plastic debris that was skimmed with fine-scale nets from the sea surface at several locations in the North Atlantic Ocean during SEA research cruises. Most were millimeter-sized fragments.
"We're not just interested in who's there. We're interested in their function, how they're functioning in this ecosystem, how they're altering this ecosystem, and what's the ultimate fate of these particles in the ocean," says Amaral-Zettler. "Are they sinking to the bottom of the ocean? Are they being ingested? If they're being ingested, what impact does that have?"
Using scanning electron microscopy and gene sequencing techniques, they found at least 1000 different types of bacterial cells on the plastic samples, including many individual species yet to be identified. They included plants, algae, and bacteria that manufacture their own food (autotrophs), animals and bacteria that feed on them (heterotrophs), predators that feed on these, and other organisms that establish synergistic relationships (symbionts). These complex communities exist on plastic bits hardly bigger than the head of a pin, and they have arisen with the explosion of plastics in the oceans in the last 60 years.
"The organisms inhabiting the plastisphere were different from those in surrounding seawater, indicating that plastic debris acts as artificial 'microbial reefs," says Mincer. "They supply a place that selects for and supports distinct microbes to settle and succeed."
These communities are likely different from those that settle on naturally occurring floating material such as feathers, wood, and microalgae, because plastics offer different conditions, including the capacity to last much longer without degrading.
On the other hand, the scientists also found evidence that microbes may play a role in degrading plastics. They saw microscopic cracks and pits in the plastic surfaces that they suspect were made by microbes embedded in them, as well as microbes possibly capable of degrading hydrocarbons.
"When we first saw the 'pit formers' we were very excited, especially when they showed up on multiple pieces of plastic of different types of resins," said Zettler, who added that undergraduate students participating in SEA Semester cruises collected and processed the samples. "Now we have to figure out what they are by [genetically] sequencing them and hopefully getting them into culture so we can do experiments."
The plastic debris also represents a new mode of transportation, acting as rafts that can convey harmful microbes, including disease-causing pathogens and harmful algal species. One plastic sampled they analyzed was dominated by members of the genus Vibrio, which includes bacteria that cause cholera and gastrointestinal maladies.
The project was funded by a National Science Foundation Collaborative grant, a NSF TUES grant, and a Woods Hole Center for Oceans and Human Health Pilot award.

Mongolian president wins second term amid focus on mining curbs
ULAN BATOR (Reuters) - Mongolia's incumbent president, Tsakhia Elbegdorj, who wants more controls on foreign mining investments, has emerged as the winner of Wednesday's polls with a narrow majority of votes cast, the country's election commission said on Thursday.
Elbegdorj, 50, who has served as president since 2009, was the overwhelming favorite in the contest, played out amid worries about Mongolia's faltering economy as well as the growing role of foreign mining firms.
The commission said Elbegdorj got 50.23 percent of the votes, beating a former wrestling champion, Bat-Erdene Badmaanyambuu of the Mongolian People's Party, and health minister Udval Natsag, of the Mongolian People's Revolutionary Party.
The lower-than-expected margin of victory could be traced to low turnout, said Julian Dierkes, an expert in Mongolian politics at the University of British Columbia, adding that participation was 10 percent lower than the last election.
"The consensus was that Elbegdorj was winning and I suspect that a lot of potential voters thought he was winning anyway, and didn't vote," said Dierkes, who is in Ulan Bator to monitor the election.
Elbegdorj's narrow victory, even if it is not contested by the opposition, is not expected to allay the concerns of foreign investors worried about growing government interference in the country's booming mining sector.
The win preserves the dominance of the Mongolian Democratic Party, which won the most seats, though not an absolute majority, in last year's parliamentary vote, and heads a coalition government keen to regulate foreign investments.
Elbegdorj is a free-market advocate, but his government has increasingly adopted a more "resource nationalist" approach, with laws to give the country a bigger stake in "strategic assets", such as mines.
It also aims to rework a landmark 2009 investment pact to develop the massive Oyu Tolgoi copper and gold mine.
The vote took place amid rising concern over Mongolia's resource-dependent economy, with falling commodity prices and weakening demand from China expected to erode growth and undermine spending plans.
The economy grew 12 percent last year and 17 percent in 2011, as mining investment poured in and mineral exports to China surged.
But growth could slow to 5.5 percent in 2013, the Mongolian Investment Banking Group said this week, if the Oyu Tolgoi project is not launched on schedule.
Mongolia is in dispute with Anglo-Australian mining giant Rio Tinto over how it will repatriate profits from Oyu Tolgoi, whose launch has been delayed twice this month.
A controversial new mining bill championed by Elbegdorj will also be high on the agenda.
"The biggest implication is continuity -- his campaign was that he had done well for four years and wanted a chance to do more," said Dierkes. "But mining and resources is on the top of everyone's agenda and here he will keep going."

?MythBusters? revisit previously busted case
TV 
9 hours ago
What "MythBusters" fans want, "MythBusters" will give! In 2007, the hit Discovery show took on the case of the "Bifurcated Boat." A man who was driving a speedboat had crashed into a channel marker, and the accident had nearly split the boat in two. Sounds like speed was involved, right? Maybe not. The man claimed that he was going just a measly 25 MPH.
"MythBusters" to the rescue! With some tests, the gang busted the tale after their model boat merely glanced off their marker with little damage. But viewers complained about the bust, so the show is now revisiting the myth in its 10th season, and Discovery is sharing an exclusive look at the second attempt to bust the myth with TODAY.com.
"Our results were less than spectacular," Grant Imahara admits in the clip. "But according to you fans, that's because our methodology was totally wrong!"
"Because we didn't do it on water!" Kari Byron adds in the video.
Testing damage to a boat and not using a body of water of some sort? No wonder fans wanted a redo!
And it turns out there were some other problems too when testing the myth the first time. (Including an accident involving dropping one boat. Oops!) Take a look at some of the blunders, as well as what the "MythBusters" plan to do to make this attempt more accurate:
"MythBusters" airs Wednesdays at 9 p.m. on Discovery.

Grants will support islet cell transplantation and insulin sensor projects
Irvine, Calif., June 26, 2013 Two UC Irvine research groups have received $2.27 million from the JDRF to develop innovative methods of treating and possibly curing Type 1 diabetes.
The JDRF, formerly the Juvenile Diabetes Research Foundation, awarded one grant to Jonathan Lakey, associate professor of surgery and biomedical engineering, and Elliot Botvinick, assistant professor of surgery and biomedical engineering; and another to Weian Zhao, assistant professor of pharmaceutical sciences and biomedical engineering. Lakey and Zhao are affiliated with the campus's Sue & Bill Gross Stem Cell Research Center.
With $1.27 million in funding over three years, Lakey and Botvinick will try to find a way to successfully transplant encapsulated, stem cell-created pancreatic islets. In Type 1 diabetes, the pancreas cannot produce insulin a hormone key to regulating carbohydrate and fat metabolism in the body making daily insulin treatments necessary.
The pancreas, an organ about the size of a hand, is located behind the lower part of the stomach. It makes insulin and enzymes that help the body digest and use food. Throughout the pancreas are clusters of cells called the islets of Langerhans. Islets are composed of several types of cells, including beta cells that make insulin.
In a previous study, Lakey helped show that transplanted encapsulated islets can create and secrete insulin. A major hurdle, though, is overcoming immune-system rejection of these transplanted islets.
The Lakey-Botvinick team which includes researchers and products from UC Irvine, the University of Oxford, the Netherlands' University of Groningen, Eastern Virginia Medical School, Islet Sheet Medical in San Francisco, Islet Sciences in New York and Danish pharmaceutical company Novo Nordisk will explore the use of isolated islets in which the cells are encased in an ultrapure algae membrane.
The encapsulation chemistry allows for selective permeability, meaning that some small molecules, such as glucose and insulin, can pass across the barrier, while large antibodies and immunological molecules are blocked from entering into the space containing the islets.
"Perhaps the greatest challenge in the field of islet transplantation is to make the metabolic benefits available to patients with Type 1 diabetes without the need for chronic immunosuppression," said Lakey, who's also director of UC Irvine Health's Clinical Islet Program. "I believe that this technology has great promise for realizing our goal. And this welcome support from the JDRF should speed our progress."
With the other grant, Zhao and his colleagues will try to develop an insulin sensor for the JDRF's Artificial Pancreas Project, which supports the creation of an automated system to dispense insulin based on real-time changes in blood sugar levels. Central to such a device is a mechanism that can accurately determine blood insulin amounts to provide feedback control for the artificial pancreas.
Existing systems deliver insulin via a pump under closed-loop control using data from a continuous glucose sensor. They are, however, associated with severe risks especially insulin overdose when any of their components malfunction.
Zhao will receive $1 million for the two-year effort, with the potential for further funding if his team comes up with a promising model. "Integrating a real-time insulin sensor into the artificial pancreas system will allow us to precisely monitor and control the levels of both sugar and insulin, ultimately leading to safe and effective management of diabetes," he said.
Other UC Irvine researchers involved in these projects include Bernard Choi, associate professor of surgery and biomedical engineering; Dr. Clarence Foster, clinical professor of surgery and chief of the School of Medicine's transplantation division; and Frank Zaldivar and Dr. Pietro Galassetti with the Institute for Clinical & Translational Science.
