A massive storm system has dumped more than 10 inches of rain over San Antonio, leaving the Texas city flooded and at a standstill.

Texas Public Radio's Ryan Loyd reports the area is still under a flash flood emergency. Ryan filed this report for our Newscast unit:

"Some people didn't have time to make it to safety in rain drenched San Antonio. A woman died when raging flood waters swept her away in her car. So much rain fell that it floated a city bus. Major highways are completely submerged.

"Lightning strikes started home fires, and an apartment roof collapsed because of water on top of the building.

"Mayor Julian Castro is urging people to stay inside because more rain is expected.

"'We want folks to stay home, if at all possible, and if they do drive, then to observe these low water warnings and to use common sense,' Castro said.

"Even though San Antonio is no stranger to flash flooding, this is the second wettest rain event in a single day, with only the flood of 1998 topping it."

The San Antonio Express-News is keeping a close watch on the situation. They report that in one neighborhood, 54 people have had to be rescued.

"No one was injured but the losses are likely to be great as residents described water levels that poured through their house windows, swallowed up trucks and was chin-high," the paper reports.

It was cold and rainy today in Boston. Still, thousands of runners laced up their shoes and headed to Kenmore Square.

That's the site of the final mile marker for the Boston Marathon. On April 15, when two bombs exploded near the finish line, thousands of runners could not finish the most illustrious road race in the world.

Today, thousands tried to remedy that with a one-mile run that covered the final stretch of the Boston Marathon. J. Alain Ferry, who organized the One Run, told New England Cable News, it was their chance to "to run that final mile, stolen from us."

That means athletes joined spectators, runners, the injured and those who didn't have the opportunity to finish in a do-over of the final mile of the Boston Marathon.

Kyle Shade, 26, crossed the finish line carrying the Chinese flag. He told us the before the race began, race organizers were asking for a volunteer to run with the flag in honor of Lu Lingzi, one of the three spectators who were killed in the blasts.

"I walked up and volunteered to help show that she is just as part of Boston as anyone else," Shade said.

He said people were moved by today's run. But it wasn't all sadness. He said that as he got closer to Copley Square, the street got louder. Spectators — "probably more spectators than runners" — shouted their support and they banged on their cow bells.

"It was a mixed emotion," Shade said, "some sadness and a lot of relief. I think it brought a lot of closure to a lot of people."

Shade did get to finish the Boston Marathon on April 15. He finished at 3:36:51, a good 30 minutes before the first blast. But he wanted to be there today to support others and find some closure himself.

He said the run also sends a message.

"We'll keep running," he said. "There's nothing they can do to stop Boston."

President Obama greets a Marine after forgetting to salute him while boarding Marine One on the South Lawn of the White House.

As President Obama boarded Marine One on the South Lawn of the White House on Friday, he didn't return the salute of the Marine standing at the base of the stairs.

Obama realized it once he got into the helicopter, so he turned around and shook the Marine's hand. Here's video of the moment:

As happens with anything to do with the presidency, Obama's forgetfulness unleashed scrutiny and criticism.

But, perhaps, the more interesting thing to emerge from the coverage is a 2009 piece from The New York Times.

In it Carey Winfrey, the retired editor of Smithsonian magazine and a former Marine, talks about the history of the presidential salutes. He points out that his USMC instructor taught him never to salute without a hat or when he was out of uniform.

He goes on to say that the tradition of presidents — sans hat nor uniform — to return salutes started in 1981 with President Ronald Reagan. Winfrey explains:

"He had sought advice on the matter from Gen. Robert Barrow, commandant of the Marine Corps. According to John Kline, then Mr. Reagan's military aide and today a member of Congress from Minnesota, General Barrow told the president that as commander in chief he could salute anybody he wished. And so it began."

Two freight trains collided in Scott County, Mo., early Saturday morning, leaving seven injured and collapsing an overpass.

KMOV-TV reports:

"Scott County Sheriff Rick Walter says a Union Pacific train t-boned a Burlington Northern train that had just made it through an intersection.

"The collision caused one of the trains to derail and hit a pillar under the overpass causing it to collapse. At least a dozen train cars derailed.

"Walter says two vehicles were on the overpass when it collapsed. Three people in one vehicle and two people in another vehicle were taken to a nearby hospital with arm and ankle fractures."

Reuters reports the train engines caught fire after a disel fuel leak, but firefighters were able to extinguish it.

"The National Transportation Safety Board dispatched a team to investigate the collision and bridge collapse," CNN reports.

Of course, this news comes just days after a bridge collapsed in Washington state, plunging two vehicles into a river and injuring three people.

Anibal Sanchez of the Detroit Tigers reacts after striking out Justin Morneau of the Minnesota Twins to end the game on Friday.

You've gotta feel for Detroit right-hander Anibal Sanchez.

He was cruising toward a no-hitter against the Minnesota Twins Friday night. It was the ninth inning, two outs to go, the count was 1-1 on Joe Mauer.

For his 121st pitch, Sanchez hung a pitch over the heart of the plate. Mauer delivered a bullet to center field, spoiling Sanchez's no-hit bid.

As the baseball gods are wont to do, it set up a trifecta of statistical curiosities. According to reports from the AP and ESPN:

— This is Sanchez's fourth career one-hitter. This is the second time during the past three seasons, he's had a no hitter broken up in the 9th inning.

— Mauer, for his part, seems intent on dashing the dreams of Major-League pitchers. This was the third time he breaks up a no-hitter in the ninth.

— Last season, Major League Baseball saw seven no-hitters. This season, we haven't seen any but there have already been five one-hitters.

Before you take our headline seriously, by the way, we should note that Sanchez threw a no-hitter, back in 2006 when he was a Florida Marlin.

"In the end, he got the hit," Sanchez told MLB.com. "But I feel good. I'll take my nine innings."

Authorities in Moore, Okla., just released some of the calls that were made to 911 during the EF-5 tornado that devastated the city.

They're harrowing and they offer a glimmer of the chaos and emotion that followed the storm.

During one of the calls, a man tells the dispatcher that the tornado has "cremated" a daycare.

"We need help bad," the man says. You can hear the sounds of children crying in the background. "We need help bad. We got tons of babies in here."

Another woman calls just as the tornado is approaching her. She asks where the tornado is. She sounds desperate and the dispatcher can only give her one piece of advice: "You need to get in shelter!"

The woman replies, "I can't go any place but my closet."

CBS News has posted the audio:

Gnomes marched their way into one of England's most prestigious gardening events this year. The 100th annual Chelsea Flower Show, which ends Saturday, opened its gates to the flower-friendly creatures for the first time.

Gnomes decorated by celebrities made their debut at the show and are now up for auction on eBay to raise money for a campaign that encourages school gardening. The highest bid for the seedling gnome decorated by Elton John tops 2,000 pounds. The figurines are available until Sunday at midnight.

"Alternately loved and loathed, the gnome epitomises the social divisiveness of garden design," garden historian Dr. Twigs Way wrote for the BBC.

That divisiveness has been playing out among the show participants, The New York Times reports:

"Some exhibitors went proud and loud, putting gnomes in places they would not be missed, like in the middle of the grass. Others seemed to feel that gnomes may be fine for other people, but certainly not any people they know, or want to know. One renowned landscape architect, Robert Myers, hid a gnome in a tree in his display, lost his nerve and took it out again before the judges could see it."

Way, author of Garden Gnomes: A History, tells NPR's Scott Simon that gnomes were brought to England from Germany, where it was believed that the "mythical folk" helped in the garden and on the farm. When they first arrived in England during the Victorian period, gnomes were all the rage — and expensive.

"But the link with Germany, I'm afraid, was their undoing," she says, "because, of course, as soon as the first world war broke out, not only could you not get German gnomes anymore, but of course people didn't really want German gnomes anymore."

Then, in the 1940s and '50s, garden gnomes were back in style. Way says the animated film Snow White and the Seven Dwarfs helped give them a boost.

Whether to include gnomes in the Chelsea Flower Show has been under debate for some time, she says.

"When the [Royal Horticultural Society] started having the show [in 1913], they put a blanket ban not just on gnomes, but on any colorful, mythical creature," Way says.

"For about the last decade or so, there's always been somebody that tries to sneak in a garden gnome because what they want to do, really, is say, 'Who is this garden show for? Is it for the suburban gardeners who may love their gnomes? Or is it just an exclusive show at the high end?' "

A relative of one of the children who died after a fire on a school bus, cries over the coffin, on the outskirts of Gujrat.

Mohsin Raza /Reuters /Landov

A fire onboard a school bus left at least 15 children dead in Pakistan Saturday morning.

The New York Times reports the private school bus caught fire near the town of Gujrat, when the driver tried to switch from using gasoline to natural gas.

"Because of high petrol prices, most public transport vehicles in Pakistan have been fitted with compressed natural gas kits, which, although cheaper, often pose a safety threat," the Times reports. "There are an estimated 2 million vehicles that run on compressed natural gas, or C.N.G., in Pakistan."

Unfortunately, the AP reports all the children who died burned to death.

The AP quotes police officer Mohammed Rasheed as saying 17 children had died.

Asif Bilal Lodhi, a civilian official, tells the Times that police are now looking for the driver, who Lodhi said fled without helping the children.

Gujrat, by the way, is about 120 miles southeast of Islamabad.

A U.S. district court has ruled that Arizona Sheriff Joe Arpaio's department has violated the rights of Latino drivers by racially profiling them as part of a crackdown on illegal immigration and issued an injunction to halt the practice.

The decision on Friday marks the first time that the hard-line Maricopa County sheriff's office has been found to be engaging in systematic racial profiling.

In 2010, Arizona passed a law that set the legal framework for Arpaio's actions, including a provision that allows police to check a person's immigration status if he is pulled over for any other reason. While the U.S. Supreme Court struck down most of the law last year, it left in place the so-called show-me-your-papers provision.

The Associated Press reports:

"It also backs up allegations made by critics that Arpaio's officers rely on race in their immigration enforcement.

"Snow also ruled Arpaio's deputies unreasonably prolonged the detentions of people who were pulled over.

"A small group of Latinos alleged deputies pulled over some vehicles only to make immigration status checks.

"Arpaio has denied the allegations."

Steve Shadley of member station KJZZ reports from Phoenix:

"The court order blocks Arpaio from conducting immigration sweeps and using race or Latino ancestry as a factor in determining to stop any vehicle in Maricopa County with a Latino occupant.

"Maricopa County Attorney Bill Montgomery's office said it would not comment, KJZZ said."

The ACLU Immigrants' Rights Project, which has opposed the Arizona law and similar laws in other states, called Friday's ruling a "great day for all the people of Maricopa County."

Speaking to KJZZ, the Rights Project's director, Cecillia Wang, said that "for too long this sheriff's office has been violating the rights of people around the county — people he is meant to serve."

The court "has held that practice is illegal and violates the Fourth Amendment right against unreasonable seizure," she said.

Lydia Guzman, a founder of Somos America, an immigrant rights organization, tells NPR that she's elated by the ruling but "we don't expect too much cooperation" from Arpaio.

"At the same time, we're going to be asking the federal government to help ensure that this federal order is abided by," she said.

Toronto Mayor Rob Ford at a city council meeting on Tuesday.

Nathan Denette/Associated Press

Toronto Mayor Rob Ford says he doesn't smoke crack cocaine and isn't an addict, in response to a video that surfaced recently purporting to show him using the illegal drug.

Last week Ford called the cellphone video obtained by The Toronto Star "ridiculous" and blamed the newspaper for "going after me."

Friday's comments from Ford were more emphatic.

"I do not use crack cocaine, nor am I an addict of crack cocaine," he said at a news conference. "As for a video, I cannot comment on a video that I have never seen, or does not exist."

He didn't take questions from reporters and said he'd held his silence on the matter for the past week because his lawyer advised him "not to say a word."

Last week, the Star reported that two of its reporters had viewed a video that appeared to show Ford smoking crack. The newspaper says the footage was being "shopped around Toronto by a group of Somali men involved in the drug trade." The website Gawker has also obtained the video, but it has not been verified by other news organizations.

Billionaire Paul Tudor Jones is back-peddling from remarks he made at a symposium last month that motherhood causes women to lose the necessary focus to be successful traders.

"As soon as that baby's lips touched that girl's bosom, forget it," Jones told an audience at the University of Virginia on April 26.

"Every single investment idea ... every desire to understand what is going to make this go up or go down is going to be overwhelmed by the most beautiful experience ... which a man will never share, about a mode of connection between that mother and that baby," he said. "And I've just seen it happen over and over."

But in a statement released Friday, Jones apologized for what he has called "off the cuff" remarks:

"Much of my adult life has been spent fighting for equal opportunity, and the idea that I would support limiting opportunity for any segment of society, particularly women, is antithetical to who I am and what I have done," he said. "My remarks offended, and I am sorry."

The offending comments were made as Jones, the founder of Tudor Investment Corp., a $13 billion hedge-fund firm based in Greenwich, Conn., participated in a question-and-answer symposium at the University of Virginia's McIntire School of Commerce. Prominent investors Julian Robertson of Tiger Management and John Griffin of Blue Ridge Capital were also part of the panel.

The video was obtained by The Washington Post through a Freedom of Information Act request. You can skip to Jones' controversial remarks in the video below beginning at about 2:30.

Not surprisingly, the comments haven't gone over well with some women. Writing for Time magazine, columnist Rana Foroohar shot back at what she called Jones' "convoluted argument":

"He's saying that women can't be good traders because they are too much at the mercy of their emotions. Actually, plenty of research has shown just the opposite. In the bestselling book, The Hour Between Dog and Wolf, John Coates, a former trader who is now a neuroscientist at Cambridge University, looks at just how emotionally influenced traders — mainly men — are."

The Congressional Gold Medal has been posthumously awarded to four girls killed in the 1963 bombing of Birmingham's 16th Street Baptist Church. President Obama signed the legislation Friday, as (from left) Birmingham Mayor William Bell, Dr. Sharon Malone Holder, Attorney General Eric Holder, Rep. Terri Sewell, and relatives of Denise McNair and Carole Robertson look on.

They were just little girls when they were killed in 1963, in what came to be known as the 16th Street Baptist Church Bombing. And now Addie Mae Collins, Denise McNair, Carole Robertson, and Cynthia Wesley have been awarded the Congressional Gold Medal, nearly 50 years after the attack in Birmingham, Ala.

President Obama signed the legislation Friday to award the girls — all of them 14, except for McNair, who was 11 — with the highest honor Congress can bestow upon a civilian.

The girls' deaths, from dynamite hidden under a bathroom by white supremacists, helped propel the 1964 Civil Rights Act through Congress. They were eulogized by the Rev. Martin Luther King Jr., who famously asked, "What murdered these little girls?" — a sentiment echoed in director Spike Lee's film about the incident, 4 Little Girls.

The prosecution of those responsible stretched out over decades. The last living defendant, former Ku Klux Klansman Thomas Blanton Jr., was convicted of four counts of murder in 2001.

In recent weeks, both the House and Senate passed the bill honoring the girls with unanimous votes. One of the bill's sponsors was Rep. Terri Sewell of Alabama, who attended the signing of the legislation in the Oval Office on Friday.

"It's a very proud moment for me, both as an American and as an Alabamian," Sewell tells WBUR's Meghna Chakrabarti on Friday's Here & Now. "I grew up in Selma, Ala., and it was because of the sacrifices that were made by so many, including the families of these four little girls, that I get an opportunity to walk the halls of Congress as the first African-American woman from Alabama."

As Melanie Peeples reported for NPR back in 2003, the bombing is part of a violent legacy with which Birmingham is still coping. And as Tanya Ott reported earlier this year, bombing survivor Sarah Collins Rudolph, Addie Mae's sister, continues to struggle with the lingering and painful effects of the attack.

The famous Ring Nebula is shown here in striking detail, in a composite image made from images from NASA's Hubble Space Telescope and infrared data from telescopes on Earth.

The Ring Nebula, whose iconic shape and large size make it a favorite of amateur astronomers, can now be seen in new detail, after NASA's Hubble Space Telescope captured a sharp image of the nebula. Researchers say the new clarity reveals details that were previously unseen, and a structure that's more complex than scientists had believed.

"The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle," says C. Robert O'Dell of Vanderbilt University, who leads a team of researchers studying the Ring Nebula. They combined Hubble's visible-light images with infrared data from telescopes on Earth.

The basis of the new image was captured by Hubble's Wide Field Camera 3, which was installed in 2009.

Located in the constellation Lyra, the nebula is some 2,000 light-years from Earth. The new view of the nebula allowed O'Dell's team to create a precise 3-D model of the nebula.

"O'Dell's team suggests the ring wraps around a blue, football-shaped structure. Each end of the structure protrudes out of opposite sides of the ring," according to NASA.

By comparing the recent examination of the Ring Nebula with data from 1998, researchers determined that the nebula is expanding at more than 43,000 miles an hour, with the center moving faster than the main ring.

"All of this gas was expelled by the central star about 4,000 years ago," NASA says. "The original star was several times more massive than our sun. After billions of years converting hydrogen to helium in its core, the star began to run out of fuel. It then ballooned in size, becoming a red giant. During this phase, the star shed its outer gaseous layers into space and began to collapse as fusion reactions began to die out. A gusher of ultraviolet light from the dying star energized the gas, making it glow."

When this image of the Ring Nebula was captured in 1998, it was the sharpest view yet of the famous nebula. It's now seen in new detail, revealing a more complex structure.

Former Guatemalan President Alfonso Portillo speaks with journalists in Guatemala City before boarding a plane for the U.S. on Friday.

Former Guatemalan President Alfonso Portillo has been extradited to the United States, where he faces charges of laundering tens of millions of dollars through U.S. banks.

Portillo, who served as president from 2000 to 2004, was snatched from a hospital bed in Guatemala City, where he was recovering from liver surgery. He was placed on an airplane bound for New York, according to his lawyer, Mauricio Berreondo.

The former president is accused of laundering $70 million in Guatemalan funds through U.S. banks. He was taken from the military hospital on orders of Interior Secretary Mauricio Lopez Bonilla, Berreondo said.

"I blame the government for what could happen to him," the lawyer said. "Portillo is sick and there are several pending appeals."

"This decision is an important affirmation of the rule of law and due process in Guatemala," the U.S. Embassy in Guatemala said in a statement. "We commend the Guatemalan authorities in the strengthening of the rule of law and the fight against organized crime and corruption."

In 2009, a U.S. grand jury said Portillo should face charges and Guatemala's supreme court endorsed an extradition request that was rubber-stamped by then-President Alvaro Colom, Reuters reports.

Two years later, a Guatemalan court cleared Portillo of local embezzlement charges, but the U.S. extradition request stood.

The Associated Press reports that "in the U.S. case, Portillo allegedly deposited the money in Miami and transferred it to a Paris account in the name of his ex-wife and daughter."

The Federal Trade Commission is in the early stages of opening an antitrust probe into how Google runs its online display advertising business, according to a report by Bloomberg News, citing sources who want to remain anonymous because the FTC has not announced the probe.

Google took the lead in the growing display ad market in 2012. Industry analysts at eMarketer.com predict that the search and technology company will book $3.11 billion in display ad revenues this year, topping rivals Facebook and Yahoo. Twitter is also expected to continue its strong growth in the field.

"FTC investigators are examining whether Google is using its position in U.S. display ads — a $17.7 billion industry that includes the sale of banner ads on websites — to push companies to use more of its other services," Bloomberg reports, "a practice that can be illegal under antitrust laws, the people said."

The news of a possible new inquiry into Google's business practices comes nearly six months after the FTC shut down its antitrust probe of the company's search service. That inquiry was closed after Google agreed to stop "scraping" other sites for user reviews and other content.
