Open access resource reveals new genes and pathways linked to human disease

Researchers have created a large new resource of more than 900 genes switched off one-at-a-time in mice to discover which genes are important for a wide range of biological functions such as fertility or hearing.

This resource, known as the Mouse Genetics Project, screens for characteristics and early signs of disease, revealing many new functions for well-known genes, as well as for genes with no previously-known role in disease. Many of these variations in body function are likely to underlie human diseases.

The human genome has more than 20,000 identified genes, but our understanding of what they do and how disease results from their malfunction is quite limited. Studies using mice are central to understanding how genes function and how variation to genes causes disease. Mice share the vast majority of their genes with humans and researchers can use mice that have a specific gene switched off to start to unravel human disease.

The Mouse Genetics Project provides researchers and clinicians with a wealth of freely available clinical and biological information that will help find new treatment strategies and options for a wide range of diseases. Furthermore, research groups worldwide can use these new mouse lines to continue the work of investigating the fundamental mechanisms of disease, as the mouse lines are openly available to researchers.

"Our project has revealed many completely unexpected associations between genes and traits like body weight, emphasising how difficult it is to predict the importance of a gene in disease until there is a model like the mouse to give us clues," says Professor Karen Steel, lead author from King's College London and Honorary Faculty at the Wellcome Trust Sanger Institute. "There are many paths to developing a disease that aren't immediately obvious. This resource provides an efficient way to uncover these paths.

"This resource is the largest collection of mouse lines available to researchers where all other genes are virtually identical except the gene switched off. Together with the careful optimisation of their environment and the systematic analysis of a wide range of characteristics in each line, we are able to detect features that otherwise would be missed."

So far the team have individually switched off more than 900 genes in mice to understand how they function and how they relate to disease. Rather than tunnelling in on one or two potential effects, the team are systematically studying a large number of potential outcomes to build an entire catalogue of gene functions and effects. The new report published today describes the detailed analysis of the first 250 lines to undergo this systematic health screen.

The researchers discovered that newly identified and unknown genes are just as likely to underlie disease features as known genes. This finding emphasises the value of a broad approach to studying diseases rather than the current tendency of researchers to focus on well-known genes. The availability of mouse models and publicly-available information about their characteristics should encourage a broader understanding of the full extent of gene function and how genetic changes can result in disease.

The team revealed that a gene, Kptn, previously thought to be linked to deafness could actually be associated with obesity. They found that when the gene is switched off in mice fed with a high fat diet, the mice gain weight faster than those that have working copies of the gene. This is one of the many examples of genes identified by the team to have a surprising new role in disease.

Among the genes reported in detail are 26 brand new mouse models for human diseases, allowing detailed investigation of the underlying biology of these diseases. For example, variations to the gene SMS can cause a rare, inherited condition associated with both mental and physical difficulties, called Snyder-Robinson syndrome. The team switched off the same gene in mice and the results reproduced those seen in the human disease. They also detected male infertility, suggesting a new feature of the disease that may not have been recognised in humans with SMS mutations.

"Not only is the biological information openly available to the wider scientific and clinical community, but so are our mouse models," says Dr Jacqui White, first author from the Wellcome Trust Sanger Institute. "Already 447 research teams in 25 different countries across the world are using our mouse lines and taking this research to new levels. Our hope is that other research teams will take our research forward to better understand disease and develop new and effective therapies against these diseases."

"This resource is revealing a wealth of information about human disease that has great potential for improved diagnosis and treatment options," says Professor Philip Beales Professor of Medical Genetics at the Institute of Child Health, University College London, and a consultant clinical geneticist at Guy's Hospital and Great Ormond Street Hospital. "This is just the start of a long journey, but I'm excited by the research that this resource will allow us to do."

Notes to Editors

The Mouse Genetics Projects has been awarded three Wellcome Trust strategic awards to investigate developmental biology, infection susceptibility and bone disease traits. It is extremely difficult to predict which genes are involved in disease. These programmes will look at different aspects of disease traits more closely and link both common and rare human diseases to malfunctioning genes.

Earth's gold came from colliding dead stars

[unable to retrieve full-text content]We value gold for many reasons: Its beauty, its usefulness as jewelry, and its rarity. Gold is rare on Earth in part because it's also rare in the universe. Unlike elements like carbon or iron, it cannot be created within a star. Instead, it must be born in a more cataclysmic event -- like one that occurred last month -- known as a short gamma-ray burst.

Iowa View: Bad Policies in Education Reform law - Interfaith Alliance ...

by Connie Ryan Terrell

Des Moines Register, Iowa View,?7.16.13

From all the pounding of chests and declarations of victory from both sides of the aisle, one would think the 2013 education reform bill passed by the Iowa Legislature and signed into law by the governor was the panacea for Iowa?s education system. The truth is a large portion of the legislation will come back to haunt the Legislature.

The education reform bill was a broad, meandering piece of legislation that included items such as student assessments, teacher compensation guidelines and allowable growth. The bill also included special interest demands, such as decreasing parental accountability by making assessments for home school children optional, limiting the state?s oversight of non-public schools, permitting home school parents to teach driver?s education, and allowing home school parents to teach up to four unrelated students with little oversight by the state.

In separate legislation, increased financial support was provided to non-public schools through direct funding and tax credits. Together, the legislation moves our state further down the road toward privatization and inequity in education, fueled by the misleading notion of ?parental choice.?

As an example, any parent can choose to home school their child. The oversight of the student?s education includes a partnership between the family and the public education system. The partnership supports a parent in teaching the child at home but also ensures the parent successfully fulfills his or her obligation through assessments.

The education reform weakens that partnership. Now, the state has limited oversight and parents have no real accountability. One hopes all home school parents have the capability to fulfill the promise of a good education. However, logic should tell you not all parents can meet that obligation, and now the children in those families will undoubtedly fall through gaping cracks.

Privatization of education continues to be prioritized in line items of the state budget. Parents who choose a non-public school still receive the benefit of state aid through transportation, textbook and technology supports.

Additionally, Iowans are encouraged to make contributions to benefit non-public schools through school tuition organizations and receive a tax credit. Line items and tax credits continue to grow, using precious public tax money to subsidize private education choices.

Nationally, there is momentum toward privatization of education in our country. Privatization is a strategy of religiously conservative organizations to replace public education with private options that support their world view. Conservative organizations find themselves strangely in bed with for-profit businesses.

Religious conservatives tout parent choice, home schooling, online options, vouchers and charter schools. For-profit businesses have cropped up across the country to fill a niche and make a buck on the backs of children through private schools, charter schools and online learning. It?s a marriage made in heaven.

Progressives fall easily into the trap. What?s the harm? Isn?t choice a good thing? Shouldn?t parents have the final say?

Although to date, Iowa has placed limits on the business side of this equation, legislators continue to chip away at our state?s responsibility in oversight and accountability with home schooling and non-public schools. Each of these strategies alone may appear to do only minimal harm, but together they significantly weaken our educational system.

When the state creates bad public policy by relinquishing oversight and reducing accountability and continues to shift public funds from public education to private entities through allocation or credit, the entire education system is weakened. This negatively affects all students, but the greatest burden is placed on students in public schools.

Iowans believe in our schools and understand that a healthy and vibrant public education system is the greatest equalizer for all students. Legislators can claim a victory, but, in reality, education in Iowa lost this year.

Future legislative sessions should consider reversing course and put state oversight and parental accountability back into the private education part of the equation. In addition, with our country?s long tradition of separating the institutions of religion and government, the state should stop funneling public resources directly or indirectly to non-public schools, most of which are religiously based. It?s simply bad public policy.

Marissa Mayer, Year 1: Yahoo has energy, but ad business challenged

SUNNYVALE -- In her first year as CEO at Yahoo (YHOO), Marissa Mayer has revamped products, shrugged off controversy and presided over a corporate shopping spree that has gobbled up 17 smaller companies, all in an effort to re-energize the struggling Web giant.

At the same time, Yahoo's stock has surged more than 70 percent, thanks to a long-held stake in a high-flying Chinese Internet firm. "The company is worlds ahead of where it was a year ago," said longtime shareholder Eric Jackson, a hedge fund investor

Yahoo CEO Marissa Mayer smiles during an announcement that Yahoo acquired the Tumblr blogging site in order to upgrade its Flickr site, in New York, May 20, 2013. YAFP PHOTO/Emmanuel DunandEMMANUEL DUNAND/AFP/Getty Images ( EMMANUEL DUNAND )

and outspoken critic of previous Yahoo bosses.

But Yahoo's most important advertising business has continued to show an alarming decline. And as Mayer approaches her anniversary at the company on Tuesday, analysts say Yahoo is far from out of the woods.

"Yahoo is trying to sell a product that fewer and fewer advertisers want," warned Karsten Weide, a media analyst for the IDC research firm. "They've been consistently losing market share."

An pioneer in the Internet industry, Yahoo is still one of Silicon Valley's most prominent companies. Its websites, email service and other programs are used by hundreds of millions of people around the world. But its influence has waned as the company missed key market shifts toward mobile

computing and social networking. Sales have sagged in recent years, and a revolving cast of chief executives was unable to stem the tide.

Mayer, a 38-year-old former Google (GOOG) executive, has warned that Yahoo's turnaround will take several years. Even so, she insists the company is on its way after a series of high-profile moves aimed at boosting internal morale and redesigning the company's online services for smartphones and other mobile gadgets, which a growing number of Internet consumers are using instead of desktop computers.

By building new products that "delight and inspire," Mayer told shareholders in June, Yahoo will attract more users, which in turn will draw more advertisers and revenue. "The future for us," she declared, "is that virtuous cycle."

While Mayer declined to comment for this article, she has outlined her strategy in recent public talks.

"What we needed to do was reinvent ourselves," she told a Stanford University audience last month. That's not easy, Mayer acknowledged, but she said the trend toward mobile computing is "so big"

that Yahoo "can catch a part of it and ride it" to success.

Some analysts say they're still waiting for results. "Marissa Mayer has been Yahoo's CEO for almost a year and the metrics associated with its display (advertising) business have not improved," Carlos Kirjner of Bernstein Research wrote in a report this month. "One could argue they have deteriorated."

Mayer was already a prominent Silicon Valley executive when she joined Yahoo. One of the first hires at Google, she rose from software engineer to senior manager while earning a reputation as a tough boss in a male-dominated field -- and as a self-proclaimed fan of quirky humor, designer cupcakes and couture.

Now she's even more in the spotlight as she tries to pull off what Joseph Grundfest, a Stanford law and business professor, described as "one of the most important turnaround efforts in Silicon Valley," along with veteran CEO Meg Whitman's similar bid to revive another struggling tech giant, Hewlett-Packard (HPQ).

Yahoo makes its money from advertising, but its revenue slid from $7.2 billion in 2008 to $4.9 billion last year, as advertisers turned to newer rivals such as Google and Facebook. During the same period, Yahoo employees were whipsawed by a series of CEOs, including cofounder Jerry Yang, tough-talking Carol Bartz and short-lived Scott Thompson, ousted last spring over false-r?sum? claims.

Soon after she was hired last summer, Mayer moved to restore morale by providing free food in company cafeterias and letting employees choose new smartphones. She also sparked a national debate by ending a policy of letting staff members work from home. But the move was applauded by some, including Yahoo employees who said it could foster discipline and collaboration.

Yahoo says job applications have increased, although the workforce has shrunk to 11,300 from 12,500 last year, without major layoffs. Mayer now enjoys an 85 percent approval rating from Yahoo workers on the job-rating site Glassdoor -- higher than the average CEO rating of 67 percent and much higher than her Yahoo predecessors.

Mayer also launched an overhaul of Yahoo's online products, revamping designs and adding new features to the company's home page, email service and Flickr photo-sharing site, among others. At the same time, she has presided over one of the busiest corporate shopping sprees in recent Silicon Valley history.

Yahoo's $1.1 billion purchase of the social-blogging site Tumblr drew headlines in the spring and raised eyebrows because the site had only $13 million in annual revenue. Mayer has vowed Tumblr will help Yahoo reach a new audience of younger Internet users.

But most of Mayer's acquisitions involved small startups, like social recommendation service Jybe and mobile game-maker Loki Studios, in deals ranging from a few million dollars to $50 million. Analysts say these helped Yahoo gain talented engineers or technology that Mayer can use to create new products for mobile devices.

Mayer has also said she's "realigning" Yahoo's ad business, after hiring Google ad executive Henrique De Castro to serve as her chief operating officer.

So far, according to Weide, "there's been little visible progress." To compete with the likes of Google and Facebook, he said, Yahoo needs to implement more automated advertising technology that will help advertisers deliver messages to consumers at exactly the right time and place.

Yahoo's display advertising sales have fallen in each of the last two quarters under Mayer. The company also makes money from another category of ads, which appear next to Internet search results, but its share of that market is shrinking, too.

Mayer's efforts and personal star power have helped boost Yahoo's share price, analysts say. But many also believe the surge is driven by investors who expect a big payout when Alibaba goes public next year. Yahoo owns 24 percent of the Chinese firm.

Meanwhile, analysts will be watching closely for signs that Yahoo's ad business is improving. Mayer is scheduled to issue another quarterly report on Tuesday.

Officials' Children Get Plum Summer Jobs At State Agency

Rosemary Bove, the $101,000-a-year state official who manages Connecticut's five "Welcome Centers" on interstate highways, didn't have to look very far for at least a couple of the young people who were hired in May to work in 13 highly-coveted summer jobs.

One of them is Bove's 23-year-old daughter ? who's been paid $12 an hour since being hired May 17 in a job eligible to last through Nov. 2. She makes $960 every two weeks.

Another is the son of Rhonda Olisky, a $74,800-a-year official in the same state agency as Bove: the Department of Economic and Community Development. Jon Olisky-Veneziano, 20, is making $14 an hour, as a returning summer worker, and makes $1,120 every two weeks; the state paid him $12,376 last year, comptroller's records show.

Rosemary Bove and the department's human resources director interviewed the candidates, including Bove's daughter, Natasha Bove, the department says. The jobs were not advertised ? although the department did set up a booth at three college job fairs to recruit a number of those hired.

Meanwhile, a 22-year-old nephew of DECD Deputy Commissioner Ronald Angelo was hired May 20 as one of four summer workers at the department's central office at 505 Hudson St. in Hartford, the agency confirmed. The nephew, Tyler Naumann, makes $14 an hour, or $1,120 every two weeks, records show.

That's three relatives that The Courant was able to confirm out of 17 summer hires at the department. DECD officials say there's nothing wrong it.

"There is no language in [the State Personnel Act] that prohibits an agency hiring an employee family member," said DECD Human Resources Director Antoinette Alphonse. She said that no family member can supervise another family member or influence his or her evaluations or promotions. "These hirings were proper!!!" Alphonse said in an emailed response to Courant questions. "These employees are not supervised by a relative.''

The employment of a few relatives for seasonal jobs is not unique to DECD, Connecticut and the innumerable towns whose recreation departments hire lifeguards in the summer.

Still, the summer hirings of DECD officials' relatives serve as a reminder that people still care about fairness even in matters of government that involve such relatively small amounts of taxpayer money. The hirings have prompted discussion among state workers that found its way to The Courant.

Part of the discussion is that some of these jobs could have been filled by young people from Hartford; at least seven of the jobs are in the DECD's city offices. None of the 17 summer workers has a Hartford address, according to documents released Friday by the DECD in response to a week-old Freedom of Information Act request from The Courant.

DECD spokesman Jim Watson said candidates were recruited at three college job fairs earlier this year ? at Western Connecticut State University in Danbury, Fairfield University, and Connecticut College in New London. "We were very pro-active" about those efforts, which involved setting up a booth and, at times, returning to a campus subsequently, Watson said. He did not know how many of those hired were recruited at those job fairs, as opposed to finding out about the jobs some other way.

One reason the duration of the summer jobs is so long ? May to November ? is that the Welcome Centers need to be staffed with people to advise tourists seven days a week through the fall foliage season, Watson said. A number of the summer workers will need to return to their studies at summer's end, but they can still get hours on weekends, Watson said.

The 13 Welcome Center jobs fall under the DECD's Office of Tourism, which is located in a separate office at One Constitution Plaza in Hartford. Most of them are spread among the five centers, which are in: Danbury on I-84 eastbound; Darien on I-95 southbound; North Stonington on I-95 southbound; Westbrook on I-95 northbound; and West Willington on I-84 westbound. The Greenwich Welcome Center is temporarily closed.

A few of the 13, including Natasha Bove, are assigned to work at the Office of Tourism at One Constitution Plaza. Her mother, whose title is community development specialist, works in the same office but another employee there supervises her, Watson said. Natasha Bove works on special projects, including "marketing and tourism website projects," Watson said, adding that she also serves as a "backup worker" at all the Welcome Centers, as needed.

Olisky-Veneziano is supervised by Rosemary Bove and works as a courier among the Welcome Centers, delivering promotional materials. He also serves as a backup worker at any of the Welcome Centers when needed, Watson said. Prior to coming to Connecticut to work in 2012, Olisky-Veneziano had been living in Florida with his father; now he lives in Berlin with his mother, his resume says. His mother is a program associate for DECD's Office of the Arts, which also is located at One Constitution Plaza.

Olisky and Rosemary Bove declined comment. Natasha Bove, Naumann and Olisky-Veneziano could not be reached for comment.

DECD Commissioner Catherine Smith, whose signature was on each of the 17 letters appointing the candidates to their summer jobs, could not be reached for comment Friday.

Although Alphonse cited the State Personnel Act in saying all of the hirings were proper, there are other laws that apply to such situations ? including the statutes known as the Code of Ethics for Public Officials. The code prohibits a state official from using his or her office to benefit a family member financially.

The director of the Office of State Ethics, Carol Carson, declined comment Thursday when asked if a public official interviewing his or her child, who then is hired, amounts to benefiting a family member financially.

But her agency routinely investigates such allegations, and weeks ago announced that a state Department of Transportation employee was fined $2,500 for failing to disclose his son's employment by a consultant on a highway project that he was overseeing, in violation of the nepotism provisions in the Code of Ethics.

In addition to the three relatives of DECD officials who were hired, at least one other candidate ? apparently not a relative ? was referred by a top department official for a job, was offered a position, but then turned it down because it did not fit in with his schedule, records show.

Bush-Palin ticket called 'GOP's only chance'

(WASHINGTON TIMES) Earlier this year, Jeb Bush told ABC that both his father George H.W. Bush, and brother George W. recommended he run for president in 2016. Mama Barbara Bush is not keen on the idea, declaring in April that ?the nation?s probably had enough Bushes.?

But in the constantly shifting equations of potential Republican hopefuls for future president and vice president, the former Florida governor?s name has been tied with another former governor: Sarah Palin.

The pair have now been framed as a ?the GOP?s only chance? in the race by American Thinker contributor Michael Sheppard.

McKenzie appointed as Wallaby coach

The Australian Rugby Union has confirmed that Ewen McKenzie will take over from Robbie Deans as head coach to the national side with immediate effect after the latter resigned in the wake of the 2-1 seriues defeat to the Lions.

An ARU statement read: ?Qantas Wallabies head coach Robbie Deans has announced this morning he is stepping down from the role effective immediately.?

The governing body had already been reviewing Deans? performance as he approached the end of his contract, which was due to expire at the end of the year. We have been conducting that due diligence over the last few months, taking into account broad criteria for coach selection,? Pulver said.

?Consideration was given to leadership skills, discipline, coaching capability, coaching records, and important factors such as character, values and style of play. Therefore, we were well prepared depending on how the year unfolded.

?Robbie resigning in the wake of the Lions Tour did not catch us unprepared to move forward with a replacement.

?(McKenzie?s) opportunity comes quickly, with the Castrol EDGE Rugby Championship and the opening match of that competition ? the Bledisloe Cup showdown with the All Blacks on August 17th.?

McKenzie is targeting Bledisloe Cup success. The 48 year old McKenzie made 51 appearances for Australia at prop and was part of their 1991 World Cup-winning squad before carving out a successful coaching career at home and overseas.

He is excited at the opportunity to coach his home country and is hoping to make an immediate impact. ?I?m really pleased to be able to accept the job of Wallaby coach,? he said today.

?I?m pretty proud right now, pretty privileged to be able to get that opportunity. Right here and now I?ve been asked to do a very specific job, that job starts in five weeks? time. There?s no better coaching assignment than to pit yourself against the All Blacks.

?I?ve played and coached in a bunch of Bledisloe Cup games (as A team coach) and to get another crack at the All Blacks is terrific. I?m really looking forward to the challenge of taking them on and from that, good things can flow.

?It?s a really important time in Australian rugby. On the field, people will worry about where the Wallabies are at. I?m looking forward to the challenge of making a difference in that and in the game as a whole.?

Deans led the Wallabies in 74 Tests having been appointed early in 2008. He said: ?I wish to take this opportunity to thank everyone involved in Australian rugby for their support through the duration of my tenure. It has been a rewarding five years and I am proud of all that we have achieved.

?Most especially I would like to thank the players for their efforts and wish them all the best going forward.?

Pulver added: ?Robbie came into the job in 2008, improved our away record almost immediately, delivered a Tri Nations title in 2011 and has been a significant part of a Lions Tour that overshadows any other rugby event in Australia since the 2003 Rugby World Cup.

?We wish him all the best in his future endeavours and to build further on what is one of world rugby?s most impressive coaching resumes.?

D-Backs' Corbin wins 10th? |? Oswalt strains hammy

By BOB BAUM

AP Sports Writer

Associated Press Sports

updated 7:09 p.m. ET July 7, 2013

PHOENIX (AP) - At last, Patrick Corbin has that elusive 10th victory.

The 23-year-old left-hander gave up three hits in eight innings and the Arizona Diamondbacks beat Colorado 6-1 Sunday for their fifth straight win and a dominant three-game sweep of the Rockies.

Corbin (10-1) struck out 10 in his seventh attempt at win No. 10.

"He deserved it a long time ago," Arizona catcher Miguel Montero said. "Obviously he hasn't had run support. That's why it's been tough. ... He should be 15-0, to be honest."

Picked a day earlier for the All-Star team, Corbin also hit an RBI double as the Diamondbacks outscored the Rockies 22-2 in the series.

"It felt like every inning I got a little bit stronger," Corbin said. "Just one first pitch right down the middle for the homer, but other than that I felt good with my changeup and my slider."

The slider was particularly devastating to the aggressive Colorado batters.

"They couldn't lay off it," Corbin said.

His previous 10-strikeout performance also came against Colorado.

The Rockies lost more than the game. Star outfielder Carlos Gonzalez left after swinging at a pitch in the ninth inning. Afterward, he said it was a sprain and nothing serious. He said it first bothered him when he struck out in the sixth inning.

Starter Roy Oswalt (0-4) exited with what initially was called a strained left hamstring in the second. Oswalt's injury could keep him out for some time because he said he "heard it pop."

"We lose Oswalt in the second inning and things aren't going well, then I hurt myself with a swing," Gonzalez said. "We are going through a bad moment. I hope it will get better. We are in a bad situation right now. We have to play better. We just don't look the same, playing. It is a bad time. `'

Jonathan Herrera broke up the shutout with a home run in the eighth.

Aaron Hill doubled twice and drove in two runs for Arizona. Paul Goldschmidt had an RBI double.

The sweep followed a rough road trip that saw the Diamondbacks lost seven of eight before salvaging the final two against the Mets in New York, exhausting the bullpen in the process.

Then each of Arizona's starters in the Colorado series - lefties Tyler Skaggs, Wade Miley and Corbin - went eight innings. Montero called them "the young busters."

"They (Skaggs and Miley) did a great job and I wanted to go out there and try and do better than them," Corbin said. "When we're putting up runs early like that it makes it a little bit easier on us and I feel like we can throw our game a little bit more."

Josh Collmenter pitched a scoreless ninth for the Diamondbacks on Sunday.

Corbin gave up a single and walk in the first, then retired 12 in a row and 20 out of 21 before Herrera's home run. He joins Randy Johnson, Curt Schilling and Brandon Webb as the only Arizona pitchers with 10 wins before the All-Star break.

The Rockies, playing the first three of 10 straight road games against NL West foes before the break, came to Arizona 2 1/2 games behind the first-place Diamondbacks and left 5 1/2 out. Colorado has lost six of seven.

Gonzalez, who sat out the series opener with a sore back, took a swing at the first pitch he saw in the ninth and hurt a finger. The trainer came out to look at it and after a tentative practice swing, Gonzalez left the game.

Eric Chavez led off the Arizona second with a double and took third on a groundout. Miguel Montero struck out, then with Jason Kubel at the plate, Oswalt spiked a pitch that bounced past catcher Wilin Rosario. Oswalt ran to the plate to cover as Chavez scored but came down awkwardly and immediately had trouble walking as he went to the dugout.

"I never had a hamstring pull in my life. I don't know the timetable on it," Oswalt said. "I felt it when I was trying to slow down. They got it so wet around the plate I kind of slipped. I was trying to change direction a bit. He threw the ball up a little bit. I don't really know exactly when it popped. I just felt it pop and knew right away that there was no way I was going to be able to go back on the mound."

Reliever Edgmer Escalona came on and got in trouble in the second.

He walked Corbin to start the inning, then Gerardo Parra hit his second single of the game. Hill hit a two-run double into the left-field corner, then stole third before Goldschmidt doubled.

Goldschmidt, like Corbin headed to his first All-Star game, leads the NL with 74 RBIs.

Corbin was helped by some big defensive plays. Goldschmidt made a leaping grab at first base to rob Herrera and end the second, and Chavez backhanded Rosario's sizzler to third and threw to first for the final out of the fourth.

NOTES: The Diamondbacks announced a makeup game at Texas for Aug. 1. ... As expected, LHP Tyler Skaggs will start for Arizona on Wednesday night against the Los Angeles Dodgers. ... The Dodgers send Zack Greinke (6-2, 4.30 ERA) against Arizona's Randall Delgado (1-2, 3.67) in Monday night's series opener. ... The Rockies go to San Diego, where Tyler Chatwood (4-2, 2.75) starts against Edinson Volquez (6-6, 5.26) in Monday night's opener. ... Arizona has seven left in a 10-game homestand leading to the break.

GOP Congressman to David Brooks: ‘Don’t Put Words in My Mouth’

Representative Raul Labrador (R., Idaho) and New York Times columnist David Brooks had a heated exchange today.

Discussing immigration, Labrador, who was formerly a member of the House immigration gang, said on Meet the Press, ?If you listen?to?what the CBO?said, they said it?s going?to?be?a third and 50 percent reduction in?illegal immigration.??

?That means that every five year?we?re going?to?have?to?do?another Reagan?amnesty,? he added. ?What the American people want is?a secure border.?

?The CBO said that it would reduce?it by?a?third?to?50 percent,? Brooks responded. ?What I hear the?congressman saying is he won?t support it?unless it is 100 percent because we?d?have?to go back and?do?a?Reagan.?

?That?s not what I said,? shot back Labrador. ?Don?t put words in my mouth.?

Brooks responded, ?Okay,? and continued to discuss immigration.?

The Evolution of Evo Devo | RealClearScience

The first approach naturalists took to dealing with the great variety of animals was to sort them into groups, such as vertebrates (including fish, amphibians, reptiles, birds, and mammals) and arthropods (insects, crustaceans, arachnids, and more), but between and within these groups there are many differences. What makes a fish different from a salamander? Or an insect from a spider? On a finer scale, clearly a leopard is a cat, but what makes it different from a domestic tabby? And closer to home, what makes us different from our chimpanzee cousins?

Two Planes In Near Miss Over New York - Business Insider

The Federal Aviation Administration is investigating after two planes came perilously close to each other in a near miss over New York City on June 13, the Associated Press reports.

The incident happened around 3.45pm when a Delta Airlines Boeing 747 landing at John F. Kennedy International Airport came close to a Shuttle America Embraer E170 departing from LaGuardia Airport.

In a statement released today the FAA said the planes were "turning away from each other at the point where they lost the required separation." The issue occurred after the Delta flight had missed an approach and ended up traveling in the same direction as the Shuttle America flight.

One federal official told NBC New York that the two planes had come within 200 feet of each other.

NBC New York also got hold of a recording of the air traffic control contacting the planes, which is notable for how calm everyone involved sounds. Listen below (at around 0.30 in):

Players, coaches react to protests in Brazil

SALVADOR, Brazil (AP) ? Soccer's Confederations Cup, which ends on June 30, and next year's World Cup have been among many targets of the massive demonstrations sweeping Brazil. Some protesters angry at corruption and poor public services are also complaining about the millions of dollars spent on huge stadiums in cities with dire poverty and lack of public services.

Here are some voices from the men on the fields of play:

___

Luiz Felipe Scolari, Brazil national team coach: "We all want justice in our country. Those in the government also want this. We can't only crucify them. We all want it and we will work together for that. But it doesn't happen in a day. We have to work together to tackle some issues so that hopefully in one, two, five or 10 years from now things can change."

___

Pele, Brazil's most famous former player: "There are a lot of bad characters taking advantage of this opportunity and they are hurting these peaceful protests that have been calling for what is best for the Brazilian people. I think we can't allow these bandits and bad characters to get in the way of this opportunity to make demands for our country."

___

Neymar, current Brazilian team star: "It's sad that it got to a point where we need to go to the streets to demand better conditions. The only way I can represent and defend the country is by playing football, and from now on I'll walk on the field inspired by this movement."

___

Japan coach Alberto Zaccheroni: "I am very sorry and my whole team is very sorry to see that there is a lot of tension at the moment because this means there is dissatisfaction on behalf of the people, and this is not good for society, for social life, for sport, or for anything really."

___

Italy coach Cesare Prandelli: "As sportsmen we're hoping that tomorrow there is a great football match at the stadium and that nothing happens outside the stadium. It would be a paradox if inside the stadium we're trying to put on a show for the fans and 150 meters outside the stadium there is violence."

___

Italy defender Riccardo Montolivo: "If someone protests and expresses their unhappiness they should be respected, as long as the protest is done in a non-violent manner."

___

Congressman and former Brazil striker Romario, in a video message: "Keep protesting, keep going to the streets, always peacefully. It's the only way congressmen will understand that things need to change. Congratulations. More than ever I'm proud to be Brazilian."

___

Brazil defender David Luiz: "Brazilians love their country and that's why these protests are happening."

___

Brazil striker Fred: "I'm in favor of the protests as long as they are peaceful. I'm very proud to see the people fighting to improve public transportation, health services and so many other things."

___

Brazil striker Hulk: "After seeing the people on the streets demanding improvements, it makes me feel like joining them. They are doing the right thing, what they are saying makes sense and we have to hear them. Brazil needs to improve, we all know that."

___

Ricardo Zuniga, Tales Azzoni and Andrew Dampf contributed to this report from Brazil.

68%

Rating: PG-13, for intense frightening zombie sequences, violence and disturbing images.

The MPAA rating kinda says it all. This adaptation of the Max Brooks book is a seriously intense, visceral and frightening experience. I can't recall walking out of a movie feeling this edgy and paranoid since Aliens. Brad Pitt, as a former United Nations investigator, must hopscotch the globe to determine the source of a pandemic that quickly turns people into zombies -- not the slow-moving, shuffling zombies but convulsing, flailing, ravenous freaks. There's also a ton of heavy-duty gunfire, panic in the streets, and a general obliteration of civilized society as we know it. Pre-teens who've played a lot of complicated, first-person-shooter video games probably won't have a problem with this; for the parents of anyone younger, get a babysitter.

Scientists solve riddle of strangely behaving magnetic material

June 21, 2013 ? Materials scientists at the U.S. Department of Energy's (DOE) Ames Laboratory have found an accurate way to explain the magnetic properties of a compound that has mystified the scientific community for decades.

The compound of lanthanum, cobalt and oxygen (LaCoO3) has been a puzzle for over 50 years, due to its strange behavior. While most materials tend to lose magnetism at higher temperatures, pure LaCoO3 is a non-magnetic semiconductor at low temperatures, but as the temperature is raised, it becomes magnetic. With the addition of strontium on the La sites the magnetic properties become even more prominent until, at 18 percent strontium, the compound becomes metallic and ferromagnetic, like iron.

"They knew that we could calculate x-ray absorption and magnetic dichroism, so we started doing that. It is a case where we fell into doing what we thought was a routine calculation, and it turned out we discovered a totally different explanation," said Harmon. "We found we could explain pretty much everything in really nice detail, but without explicitly invoking that local model," said Harmon.

The scientists found that a small rhombohedral distortion of the LaCoO3 lattice structure, which had largely been ignored, was key.

"We found that the total electronic energy of the lattice depends sensitively on that distortion," explained Harmon. "If the distortion becomes smaller (the crystal moves closer to becoming cubic), the magnetic state of the crystal switches from non-magnetic to a state with 1.3 Bohr magnetons per Co atom."

Ames Laboratory scientists Bruce Harmon and Yongbin Lee partnered with the researchers at the Argonne National Laboratory and the University of California, Santa Cruz to publish a paper in Physical Review Letters, "Evolution of Magnetic Oxygen States in Sr-Doped LaCO3."

This new understanding may help the further development of these materials, which are easily reduced to nanoparticles; these are finding use in catalytic oxidation and reduction reactions associated with regulation of noxious emissions from motor vehicles.

The research is supported by the U.S. Department of Energy Office of Science through the Ames Laboratory.
