Five sizzling Super Bowl moments to talk about

Ray Lewis of the Baltimore Ravens celebrates after defeating the San Francisco 49ers during Super Bowl XLVII. The Ravens defeated the 49ers, 34-31.

STORY HIGHLIGHTS

• The game came down to a controversial play in the end zone


• Women with amazing vocals inspired and entertained


• Jacoby Jones scores two remarkable touchdowns


• Some commercials touched hearts, others were meh

(CNN) -- It may not have been a great game until after the lights went out and came back up, but the Super Bowl showdown Sunday night created quite a few memorable moments on the field and off, even before kickoff.

There were powerful performances, including a much buzzed-about halftime show by superstar Beyonce.

But there was also a lack of electricity in the stadium and in some of the commercials.

And San Francisco 49ers fans are sure to get emotional over that last play they ran on offense, when two players met in the end zone and despite contact, no penalty was called.

Here are the five moments you can expect your coworkers to talk about Monday morning.

Grrrl Power

The men may have duked it out during the game. But when it came to the non-football entertainment at the Superdome, women ruled the day.

First up was Jennifer Hudson with a stirring rendition of "America the Beautiful." The choir backing her comprised of students from Sandy Hook Elementary, the Connecticut school where 20 students and six school staff were shot dead in December.

Players on the sidelines and fans on the stand wiped away tears.

"Our wish is to demonstrate to America and the world that, 'We are Sandy Hook and We Choose Love,'" the choir said in a statement.

Next, Alicia Keys belted out the "Star-Spangled Banner" as the children, in white polo shirts with green ribbons pinned to them, stood with their hands on their hearts.

"It's football. But I just cried," tweeted actor Brian Baumgartner about the Sandy Hook performance.

The big show, however, came once the 49ers and the Baltimore Ravens got through the first half.

Welcome, Beyonce.

For 12 minutes, she rocked the stage clad in above-the-knee black stiletto boots and a leather minidress.

Powered by an all-female backing band, there was little doubt Beyonce sang live -- unlike during President Barack Obama's inauguration last month where she admitted singing along to a prerecorded track.

And as if that wasn't enough girl power for the night, Beyonce was joined by her Destiny's Child bandmates, Kelly Rowland and Michelle Williams.

"My heart just stopped," tweeted actress Mindy Kaling.

She wasn't the only one. Beyonce's performance generated 5.5 million tweets!

Lack of power

For the first two quarters, the Ravens seemed unstoppable, steamrolling the 49ers to a 28-6 lead.

But then, half the lights in the Superdome went mysteriously black.

The NFL released a statement saying it was "investigating." The power company said it was not to blame and that electricity in the rest of the city was fine.

The outage left players, coaches and fans to wait, wait and wait some more.

Social media lit up.

After 35 minutes when the lights slowly went back on, so did San Francisco -- prompting many to wonder if the break in play played to the 49ers advantage.

Running back Frank Gore felt differently.

"You have to wait. Football is a game of adjustments. The elements don't matter," he told NFL.com. "I've been saying it all year, the elements don't matter in football. You've just got to learn how to make adjustments."

The real MVP?

Quarterbacks often get the glory in the Super Bowl, but wide receiver Jacoby Jones had a strong case for Most Valuable Player. He lost out to Joe Flacco.

Jones scored on two of the most incredible plays in Super Bowl history, including a record 108-yard kickoff return. It took him just 11 seconds on the clock to slice through the 49ers coverage team.

"Jacoby's been a blessing to this team," said Ravens coach John Harbaugh. "We're grateful to have him on this team."

Jones, who grew up in New Orleans, also caught a 56-yard touchdown pass -- his only reception. He fell, got up, decked a defender and sprinted at an angle toward the goal line, beating two 49ers into the end zone.

"Everybody dreams of scoring a touchdown in the Super Bowl. But two of 'em? That's what's up!" Jones told NOLA.com. "It was always a goal to win a Super Bowl. To come home and do it, that's the icing on the cake."

Jones is definitely the MVP for some Baltimoreans who bought furniture this weekend at a Baltimore store.

The Baltimore Sun reported Gardiners Furniture promised to wipe out the charges for anything purchased on Saturday or Sunday -- if the Ravens returned a kick for a touchdown to start a half.

Probably seemed like a good bet at the time.

A geek makeout makes us gag

Some of the Super Bowl commercials made us weep for different reasons.

There were quite a few that played on our sentiment, from Budweiser's "Brotherhood" to Jeep's Oprah-narrated America Will Be Whole Again" to Dodge's ode, "Farmer."

Then there was the racy GoDaddy ad that made us want to cry, burn our eyes out and have the Men in Black wipe out our memories.

In it, model Bar Refaeli shares a long kiss with a red-cheeked "nerd" that prompted its own hashtag: #NoDaddy.

"Oh my gosh those kissing noises," tweeted Chicago college student Grace Barnes.

A no-call to rue until next year

Despite trailing by 22 in the second half, San Francisco nearly won it in the final minutes.

With 1:50 left, the 49ers had the ball on the Ravens 5, trailing 34-29. It was 4th and goal.

San Francisco quarterback Colin Kaepernick tossed a throw toward the right side of the end zone where the Ravens' Jimmy Smith and the Niners' Michael Crabtree made contact.

"No flag, incomplete," CBS announcer Jim Nantz said as the ball sailed over Crabtree's head. The cameras cut to a shot off 49ers coach Jim Harbaugh making the signal for holding.

Many believe it should have been a penalty on Smith.

"There's no question in my mind that there was a pass interference and then a hold on Crabtree on the last one," the 49ers coach said.

New England wide receiver Dante Stallworth tweeted there should have been a flag, even if the ball seemed like it was so high no one could catch it.

"For all y'all saying that ball was uncatchable for Crabtree in the endzone... DUH!! Because dude held thee sh*t outta him..." he tweeted.

NFL Network commentators Warren Sapp and Steve Mariucci disagreed.

Sapp said it was obviously pass interference but Mariucci, a former 49ers coach, pointed out the Crabtree also made contact, putting his hand on Smith's helmet.

Crabtree told Yahoo Sports it was "a missed call."

"I don't want to talk about it. I don't want to think about it," he said.

Tour bus crash kills at least 8 in California

Updated 4:15 a.m.

YUCAIPA, Calif. A tour bus collided with a car and pickup truck, killing at least eight people and injuring dozens of others Sunday night on a Southern California mountain highway, authorities said.

California Highway Patrol spokesman Mario Lopez confirmed the deaths and said 38 people were taken to hospitals with injuries.

He also said the bus driver reported having brake problems as it headed down the mountain on two-lane State Route 38, rear-ending a sedan then flipping over and hitting a pickup truck that was pulling a trailer.

The bus was carrying a tour group from Tijuana, Mexico, and a representative from the Mexican consulate was at the grim crash scene, California Department of Transportation spokeswoman Michelle Profant said.

"It's really a mess up there with body parts," Profant said.

Rescuers were still searching the wreckage for victims hours later. At least two passengers were said to be trapped, reports CBS Los Angeles station KCBS-TV.

Television footage showed the bus sitting upright but turned sideways on the road.

At least seven ambulances were called to the scene, and patients were taken to several hospitals.

Arrowhead Regional Medical Center said four women had been admitted from the crash and their conditions were still being determined. Redland Community Hospital said it received one person in critical condition and one with minor injuries, while two more were en route with minor injuries. Community Hospital of San Bernardino said it had received one patient with undetermined injuries, while St. Bernadine Medical Center said it had two patients, whose injuries were being assessed.

The purpose of the tour was not immediately clear, but Highway 38 leads to Big Bear, a popular area that's home to a ski resort and other recreational locations.

Lettering on the bus indicated that it was operated by Scapadas Magicas LLC, a company based in National City, Calif. Federal transportation records show that the company is licensed to carry passenger for interstate travel and that it had no crashes in the past two years.

A call to the company was not immediately returned.

The California crash comes less than a day after a bus carrying 42 high school students and their chaperones slammed into an overpass in Boston. Massachusetts state police said 35 people were injured and that the driver had directed the bus onto a road with a height limit.

Ravens Defeat 49ers in Historic, Unusual Super Bowl

The Baltimore Ravens emerged Super Bowl champions after one of the strangest and most incredible Super Bowl games in recent memory.

It's the second championship for the Ravens, who pulled out a 34-31 win over the San Francisco 49ers at the Superdome in New Orleans.

The Super Bowl is the biggest spectacle in American sports, and each year becomes the most watched television event in history. This year, Jennifer Hudson kicked things off with a touching performance of "America the Beautiful" with a choir of students from Sandy Hook Elementary School.

Alicia Keys accompanied herself on the piano for a long, jazzy rendition of the national anthem, before the coin toss which resulted in San Francisco receiving to start the first half.

Although the game looked at one point like it was going to be a completely unexpected blow-out, with the Ravens leading 28-6 at the beginning of the 3rd quarter, the 49ers got some unusual help that turned the showdown into a much more exciting battle.

About a third of the way into the 3rd quarter, right after a record-tying Ravens rushing touchdown, the power went out at the Superdome, knocking the lights and air conditioning out in the indoor stadium. The crowd of more than 71,000 strong, along with a lot of antsy players, coaches, and staff waited for 34 minutes for the power to fully come back on and the game to resume.

In a statement, the NFL said authorities were "investigating the cause of the power outage," and law enforcement sources told ABC News it was just an issue with the building.

That didn't stop many people on Twitter from jokingly blaming Beyonce, the energetic halftime performer who surprisingly reunited shortly with her former band Destiny's Child, for shutting down the power. After her performance, even her husband Jay-Z got in on it, tweeting "Lights out!!! Any questions??"

The 49ers quickly followed the long delay with a touchdown, getting themselves right back into the game. Then just a few minutes later, they found themselves in the end zone again, and it appeared the power outage had flipped the momentum towards the 49ers.

With a score of 31-29 with more than 7 minutes left in the game, San Francisco looked poised to make the biggest comeback in Super Bowl history, but the team, trying for its 6th title, wasn't able to overcome the Ravens lead.

Baltimore was able to run out the clock, and the game ended with a final score of 34-31. Purple and gold confetti fell as the Ravens rushed onto the field and celebrated -- with some colorful language from quarterback Joe Flacco audible on the live broadcast, who was caught saying, "f***ing awesome" on CBS' cameras.

The game was already historic thanks to the match-up for John and Jim Harbaugh, the first head coach brothers to ever face each other on football's biggest stage. It was also the final game for the future Hall of Fame linebacker Ray Lewis, who is, as of the conclusion of the game retired from football.

This is the fifth season in a row that the Ravens have made it to the playoffs, led by Coach John Harbaugh, and SB XLVII MVP Quarterback Joe Flacco. It's the team's first Lombardi trophy since 2000. Their victor tonight made them the only team left in the NFL to have never lost a Super Bowl in multiple appearances.

Sneaky ninja robot silently stalks its prey

MOVE over David Attenborough. A robot that moves only when it won't be seen or heard might make it easier to sneak up on animals and film them in the wild.

Defence labs have built robots that track people through cities, avoiding well-lit areas. But cities are noisy, so if a robot keeps a certain distance it's unlikely to be heard. Tracking and filming animals in the wild is tougher because they often have keen hearing and the environment is usually quieter. Matthew Dunbabin and his collaborator Ashley Tewes at the CSIRO Autonomous Systems Laboratory in Brisbane, Australia, are teaching a four-wheeled robot to move only when intermittent sounds - like bird or frog calls - will mask its movements.

In tests, the robot picked up the sounds of things like fork-lifts, cellphones and birds, and was able to predict whether they were likely to persist long enough to cover its movement. The robot can also identify its own noise, and guess how it will vary at different speeds and turning angles - calculating what this will sound like to a target up to 50 metres away.

With the help of a camera, laser scanner and the right algorithm, the robot can figure out which vantage points will provide the best cover so it can skulk in the shadows.

Govt has to and will deliver high quality: K Shanmugam

SINGAPORE: Law and Foreign Affairs Minister K Shanmugam said the range of views expressed about the 6.9 million population projection set out in the White Paper are completely understandable.

He was speaking to reporters at a hong bao presentation ceremony at his Chong Pang Division.

He said businesses are unhappy about the lack of growth in the labour force but there are also those who are concerned about the 6.9 million figure.

"They say 'I have difficulties with infrastructure, transport, housing with today's population and you want to increase it even more, doesn't make sense,' - that's a reaction and it is understandable.

"The government has got to explain two points. The first is we have to and will solve the current infrastructure problems and second for this long term planning, whatever the size of the population, 6.9 million is not the target, the infrastructure must be adequate and deliver high quality of life.

"That has to be a cast iron position that the government has to deliver and will deliver," he said.

Body of missing American found in Turkey

STORY HIGHLIGHTS

• Body of New York woman found in Istanbul


• She disappeared almost two weeks ago


• Sarai Sierra was a mother a two


• She failed to arrive at Newark, New Jersey, airport

(CNN) -- The family of an American woman who went missing in Istanbul nearly two weeks ago is in mourning after learning that Turkish police found her body Saturday.

Steven Sierra wept during a phone call with CNN, as he waited in Istanbul to go with police to identify the body of his wife, Sarai Sierra.

Turkish police found the New York woman's body near ancient stone walls in Istanbul's Sarayburnu district, the semi-official Anatolian Agency reported. Police suspected she had been killed at another location.

Police told CNN's sister network CNN Turk that the body of the 33-year-old mother of two showed signs of stab wounds.

At least nine suspects had been detained in connection with Sierra's disappearance and death, Anatolian reported.

Sierra's family and friends first sounded the alarm last week after she did not arrive on a return flight from Istanbul on January 22.

"The last we heard from my wife was Monday morning on the 21st. She had spoken with her sister and the last thing she said was, 'I'm coming home tomorrow,' and she was excited and put a little smiley face at the end of her statement," said Steven Sierra in an interview with CNN earlier this week.

Steven Sierra spoke to CNN in Istanbul on Wednesday, after he and Sarai Sierra's brother, David Jimenez, traveled to Turkey to assist in the search.

The worried husband was periodically overwhelmed with emotion throughout the interview.

"You're hoping that she's OK wherever she's at, that she's not hurting, that she's not cold, that she's being fed," Steven Sierra said, choking back tears.

"Its difficult what's going through my mind, if our hopes and prayers are not answered. It is difficult when you have two children that look up to you, and you have to do your very best to stay strong regardless of what happens."

Sarai Sierra flew alone to Istanbul on January 7 after a friend at the last minute canceled plans to accompany her.

"She did a lot of researching about the area, about where she was going to stay, the safest places to go and the time of day to travel," friend Magalena Rodriguez said.

Sierrra was an amateur photographer who had amassed more than 3,000 followers since she joined the photo sharing app Instagram last year.

Some people she met through the service encouraged her to visit the ancient Turkish city, her husband said. They offered to act as tour guides. "You're admiring pictures, but you're getting acquainted with people that you've never met before," Steven Sierra said.

Sarai's brother said he had been worried about his sister's solo trip.

"We were nervous. Were just like 'always be mindful of what you do, be aware of your surroundings. Don't get too comfortable to the point where you drop your guard down,'" David Jimenez said.

But Jimenez and Sierra's husband said Sarai was determined to complete challenges that she set for herself.

As an example, they described how she competed in a triathlon several years ago, despite being a weak swimmer, and despite the fact that she did not own a bicycle. Instead, Sarai completed the cycling leg of the competition by borrowing a mountain bike from her husband.

After arriving in Istanbul, Sierra's photo feed displayed images of Istanbul's beautiful skyline and historic landmarks.

She also squeezed in an excursion to Amsterdam in the Netherlands and to Germany, starting January 15.

"She chose to go to Amsterdam for the graffiti," her husband said. "She informed me as far as how her time was out there. And she also had a tour guide that was helping her out there as well, who I know about and who I've spoken with personally."

Sierra returned to Istanbul on January 19. Three days later, she went missing.

Sierra had rebooked her flight to arrive back early, on January 22, in part to surprise her two sons, 9 and 11.

Days before her scheduled trip home, Sierra spoke with her father, Dennis Jimenez, via Skype to remind him of her flight number and arrival time.

When Dennis Jimenez went to the Newark, New Jersey, airport to pick Sierra up, she didn't show, he said.

The airline told him she had never checked in for the flight.

"She kept in contact with us all the time," Sierra's mother, Betzaida Jimenez, said. "And then not to hear from her? It's not like her."

After the tourist went missing, Turkish police released a surveillance camera video of Sarai at a shopping mall in Istanbul, flipping through her iPad.

The scenes from January 20 are the last known images of her.

The manager of the small private hotel where Sierra was staying reported last seeing her the day the surveillance video was shot. That was a Sunday.

Her Skype account, which she avidly used, went silent a day later. A day after that was when she missed her flight home.

The time she last talked with her family, Sierra was planning on January 21 to see the Galata Bridge and visit the Asian side of Istanbul, her husband said.

The former capital of the Byzantine and East Roman empires straddles the continents of Europe and Asia.

After Sierra's family raised the alarm that she was missing, some of her belongings -- including her passport and medical cards -- were found in her room in Istanbul, though her iPhone and iPad were not there, according to her husband.

Since Sierra's disappearance, Turkish police detained a Turkish man she had been in contact with who was identified only by the first name Talan, according to CNN Turk.

Millions of foreign tourists visit Turkey every year.

While it is not unusual to hear about foreigners being targeted by pickpockets and bag snatchers, violent crime involving foreign tourists is relatively rare.

Town mourns for slain bus driver amid Ala. standoff

Updated 9:45 PM ET

MIDLAND CITY, Ala. As the police standoff with an Alabama man accused of holding a 5-year-old boy hostage continued Saturday, a nearby community prepared to bury the beloved bus driver who was shot to death trying to protect children on his bus when the episode began days earlier.

Charles Albert Poland Jr., 66, who was known around town as Chuck, was described by folks in his hometown of Newton as a humble hero. Hundreds of people attended a viewing service for Poland on Saturday evening. His funeral was set for Sunday afternoon.

"I believe that if he had to do it all over again tomorrow, he would," said Poland's sister-in-law, Lavern Skipper, earlier Saturday. "He would do it for those children."

Ala. hostage standoff: New info on kidnapper

Authorities said Jim Lee Dykes boarded a stopped school bus filled with 21 children Tuesday afternoon and demanded two boys between 6 and 8 years old. When Poland tried to block his way, the gunman shot him several times and took one 5-year-old boy — who police say remains in an underground bunker with Dykes.

Dale County Sheriff Wally Olson said in a briefing with reporters Saturday that Dykes has told them he has blankets and an electric heater in the bunker on his property. Authorities have set up a command post at a church and have been communicating with Dykes through a ventilation pipe to the underground bunker.

Olson also said Dykes has allowed police to deliver coloring books, medication and toys for the boy.

"I want to thank him for taking care of our boy," Olson said. "That's very important."

The shooting and abduction took place in Midland City, a small town near Dothan, Ala., in the state's southeastern corner.

Newton is about three miles away, a small hamlet with fewer than 2,000 residents. It sits amid cotton farms and rolling hills sprinkled with red earth; most of the residents commute to Dothan or to a nearby Army post.

William Lisenby, a school bus driver who also taught Sunday School with Poland, was flanked by other area bus drivers as he arrived at Saturday night's viewing service for his friend at a local funeral home.

Lisenby spoke in Biblical terms when referring to Poland.

"If you'll notice the similarities there, of what Chuck did was the same thing that Jesus Christ did. These children, even though they were not Chuck's, he laid down his life to defend those children. My hat's off to him for that."

"He was a bus driver just like we are," Lisenby said. "But for the grace of God that could have been us."

Others spoke of the loss of a good man, and their hope that the little boy being held captive is alive and well and will be released soon.

"The community is real concerned," said Fred McNab, mayor of Pinckard, Ala. "You can tell by the food that's been carried over there to the church. It's just devastating. We want it to come to a resolution. We want to save that little child."

Earlier Saturday, local residents remembered Poland as a friendly, giving person.

"He's probably the nicest guy you'll ever meet," said Lonnie Daniels, the 69-year-old owner of the NAPA Auto Parts store, one of three establishments in town that was open Saturday.

Daniels last saw his friend Tuesday morning, when Poland agreed to buy a car from him. The two men shook hands and closed the deal "like gentlemen," Daniels said. Poland was to return after working his bus route to pay for the car.

"He never came back," Daniels said quietly.

Daniels said Poland had been married to his wife for 43 years. Poland was from Idaho, but his wife was from Newton. The couple lived there for decades in a small mobile home, and Poland enjoyed gardening and clearing brush from his property.

"I knew that he was always there if I needed," said Daniels, adding that Poland was an excellent mechanic with an array of tools that he lent to people in town.

Neighbors and friends said Poland did various acts of kindness for people in town, from fixing someone's tractor to tilling the garden of a neighbor who had a heart attack.

"You don't owe me anything," Poland once told a recipient of his good deed. "You're my neighbor."

Skipper said Poland and his wife would often sit on their porch, drinking coffee, praying and reading the Bible.

"They loved to be together," Skipper said.

On Saturday morning, Poland's wife wasn't home. A rack of worn trucker's caps sat on hooks on the porch, and two freshly baked pies were laid atop a cooler.

The victim's son, Aaron Poland, told NBC News that he wasn't surprised by his father's act to protect the kids on the bus.

"He considered them his children," Poland said, choking back tears. "And I know that's the reason why my dad took those shots, for his children, just like he would do for me and my sister."

Gun Violence 'Depletes Precious Natural Resource'

It took the mass shooting in Newtown, Connecticut, to prompt lawmakers to call for stricter gun legislation. But the reality is that in a city like Chicago, where 515 murders took place last year and more than 100 shooting incidents have occurred since January 1, gun violence is an ongoing issue and it has been for years. Only, these shootings have become so common that they don't make national headlines.

"We lost a classroom full of children in Connecticut which sparked national outrage that needs to be translated into action, but in Chicago, we sometimes lose a dozen or more young people every weekend," Rep. Luis Gutierrez (D-Illinois), who serves the Chicago area, said in a statement. "Too many bullets and too many guns are killing the next generation and we have got to make it stop."

Gutierrez, like many others, believe that any debate about gun violence shouldn't just take into account mass shootings that make headline news. It should also consider the chronic gun violence that takes place on a daily basis across the U.S.

In Chicago's case, many of the victims are young minorities growing up in poor, gang-ridden neighborhoods on the south and west side of the city.

Just earlier this week a 15-year-old girl who performed at President Barack Obama's recent inauguration was gunned down, The Washington Post reported.

The teen, Hadiya Pendleton, was hanging out in a park with about a dozen other young people when she was shot. Two other victims were reportedly wounded. By all accounts she was in the wrong place at the wrong time. Reports indicate that the gunman was not even aiming at her.

And Pendleton is just the latest example. Chicago police officer Ron Holt lost his son, Blair, to gun violence in the spring of 2007. The 16-year-old was shot and killed while riding a bus after school.

Holt now works with young people in the community, particularly minorities at an increased risk of engaging in dangerous behavior, to encourage them to focus on their education instead of turning to violence.

"I explain to them that if they continue to ascribe to this diabolical idea of resolving conflict with firearms they're depleting the most precious natural resource in the community, and that is them," Holt said.

What's clear is that the root of the gun problem is not just the guns. There are several factors that play a role, many of which are rarely discussed. For example, for minority youth living in urban communities characterized by poverty, violence, particularly gun violence, tends to be chronic. And the groups largely impacted tend to be African American and Hispanic.

A lot of that has to do with acculturation, according to Rahsmia Zatar, executive director of Strong Youth, a gang prevention and intervention organization. There is a sense that it's difficult to move beyond one's cultural sphere.

As a result, minorities often tend to gravitate toward other young minorities in similar situations, and turn to violence to gain a sense of control, however false it really is.

"It's easy to fall victim to feeling a sense of empowerment through violence," Zatar said. "They feel they have limited opportunities and they don't have a sense of 'I can achieve,' [or] that there is something here for me that's better."

According to the 2011 American Community Survey by the U.S. Census Bureau, more than 30 percent of Chicago's African-American population and nearly 27 percent of Hispanics live below the poverty line. Perhaps more importantly, blacks and whites remain largely segregated, with African-Americans making up the vast majority of neighborhoods in the south, and whites comprising most of the north. Latinos are somewhat more mixed, often living in "buffer" communities between blacks and whites, which could exacerbate the pressure to conform to two cultures, neither of which is entirely comfortable.

These various enclaves also suffer from a distinct gang problem. Chicago Police Commissioner Garry McCarthy told Reuters the city is plagued by the breakup of larger more established gangs into new factions that are fighting over everything from turf to money.

Then there's the city's illicit gun issue, which is bigger than New York's or Los Angeles' despite strict laws to limit weapons. Gun shops are actually outlawed in Chicago, as are assault weapons and high-capacity magazines. Handguns were even banned until 2010.

Still, in a place like Chicago it's handguns doing the most damage. According to statistics from the Bureau of Alcohol, Tobacco, Firearms and Explosives, most of the guns they recovered in Illinois were pistols, followed by revolvers and rifles. Machine guns come in a distant sixth.

Why so many guns? Gun laws in neighboring communities are not as strict, and firearms make their way into the city. According to a recent article by The New York Times, officials "seized 7,400 guns [in Chicago] in crimes or unpermitted uses last year (compared with 3,285 in New York City), and have confiscated 574 guns just since Jan. 1 — 124 of them last week alone."

And while Chicago residents are required to report the loss or theft of a handgun, that same law does not apply to all of Illinois, so a stolen firearm could easily make its way into Chicago without the owner ever reporting it missing.

The dynamics created in poor minority communities like those in Chicago combined with the sheer number of guns that make their way into such a city bear out in the overall statistics.

According to the Bureau of Justice's National Crime Victimization Survey, African Americans were disproportionately represented among homicide victims and offenders between 1980 and 2008. They were six times more likely than whites to be homicide victims and seven times more likely than whites to commit homicides.

Latinos don't fare much better. According to the National Council of La Raza, the nation's largest Hispanic advocacy organization, "Today in America, every three hours a young person is killed by firearm violence. Every 14 hours, that teen or child is Latino."

Young Latinos are especially likely to be impacted by gang violence in places like Chicago. Nationally, Hispanics are also more likely than non-Hispanics to be victims of violent crimes committed by gang members.

The impact of guns on the Latino community may explain why they're inclined to favor increased gun control. According to the Pew Research Center, while 57 percent of whites think it's more important to protect the rights of Americans to own guns than to protect gun ownership, only 29 percent of Latinos feel the same way.

Holt would certainly like to see something change. Several days after his son was killed, he received a voicemail. It was then-Senator Barack Obama. The young lawmaker had called Holt to express his condolences and to promise that if there was anything he could do in the future to help curb gun violence, he was prepared to do it. The two never spoke on the phone, but Holt remembers the message.

Astrophile: A scorched world with snow black and smoky

Astrophile is our weekly column on curious cosmic objects, from the solar system to the far reaches of the multiverse

Object: Titanium oxide snow
Location: The hot-Jupiter planet HD 209458b

There is something magical about waking up to discover it has snowed during the night. But there's no powdery white blanket when it snows on exoplanet HD 209458b. Snow there is black, smoky and hot as hell – resembling a forest fire more than a winter wonderland. Put it this way: you won't be needing mittens.

HD 209458b belongs to a family called hot Jupiters, gas-giant planets that are constantly being roasted due to their closeness to their sun. By contrast, the gas giants in our immediate neighbourhood, including Jupiter, are frigid, lying at the solar system's far reaches.

HD 209458b is also noteworthy because it is tidally locked, so one side is permanently facing towards its star while the other is in perpetual night. On the face of it, these conditions wouldn't seem to invite snow: temperatures on the day side come close to 2000° C, while the night side is comparatively chilly at around 500° C.

Snow made of water is, of course, impossible on this scorched world, but the drastic temperature differential sets up atmospheric currents that swirl material from the day side to night and vice versa. That means that any substances with the right combination of properties might be gaseous on the day side and then condense into a solid on the night side, and fall as precipitation. Say hello to titanium oxide snow.

Stuck on the surface

Although oxides of titanium make up only a small component of a hot Jupiter's atmosphere, these compounds have the right properties to fall as snow. But there was a snag that could have put a stop to any blizzards. Older computer models of hot Jupiters suggested that titanium oxides condensing in the air on the night side would snow – and remain on the relatively cool surface forever. "Imagine on Earth if you had no mechanism to evaporate water, it would never rain," says Vivien Parmentier of the Côte d'Azur Observatory in Nice, France.

Now he and colleagues have created a more detailed 3D computer model that shows that the snow can become a gas again as it falls and the temperature and pressure increase. Strong updraughts can then blow the titanium oxides back to the upper atmosphere. "The gas can come back on the top layers and snow again and again," says Parmentier.

Snowfall on HD 209458b would be like none you've ever seen. Though titanium dioxide is white and shiny, for example, the snowflakes would also contain silica oxides from the atmosphere, making them black. Since the atmosphere is also dark, snowstorms on the planet would be a smoky affair, the opposite of the white-outs we get on Earth. "It would be like being in the middle of a forest fire," says Parmentier.

Although the team studied a particular hot Jupiter, their model should apply equally to other planets of this type, suggesting hot snow is a common occurrence. Parmentier says we may have already spotted snow clouds on another hot Jupiter, HD 189733b, as spectral analysis of the planet suggests the presence of microscopic particles in its atmosphere.

David Sing of the University of Exeter, UK, who helped identify such particles on HD 189733b, says the team's new model goes a long way to explaining how titanium oxides behave on hot Jupiters. "We're pretty used to water condensing on Earth; there it is titanium because the temperatures are so much hotter."

Hot, black snow – now that would be something to wake up to.

India set to introduce death penalty in some rape cases

NEW DELHI - India's Cabinet has approved harsher punishments for rapists, including the death penalty, after a brutal gang-rape in New Delhi that sparked national outrage.

A government-appointed panel recommended the changes to ministers after the death of a 23-year-old woman who was savagely raped and attacked in a bus on December 16 and died nearly two weeks later.

The case ignited nationwide demonstrations by protesters demanding better safety for women.

The changes, which must be approved by President Pranab Mukherjee to become law, include doubling the minimum sentence for gang-rape and imposing the death penalty when the victim is killed or left in a vegetative state.

"We have taken swift action and hope these steps will make women feel safer in the country," Law Minister Ashwani Kumar told reporters late on Friday.

"This is a progressive piece of legislation and is consistent with the felt sensitivities of the nation in the aftermath of the outrageous gang-rape," he added.

On Saturday, the gang-rape victim's brother praised the Cabinet's decision to make sentences tougher for attackers, calling it a "positive initiative", according to the Press Trust of India news agency.

The changes to the rape laws were expected to be approved by Mukherjee as early as this weekend but must be ratified by parliament or they will lapse.

Under the changes, the minimum sentence for gang-rape, rape of a minor, rape by policemen or a person in authority will be doubled to 20 years from 10 and can be extended to life without parole.

Under the current law, a rapist faces a term of seven to 10 years.

The Cabinet has also created a new set of offences such as voyeurism and stalking that will be included in the new law.

Five men are being tried in a special fast-track court in New Delhi on charges of murder, kidnapping and rape in connection with the death of the student, who died from her injuries.

A sixth suspect faces trial in a juvenile court.

The physiotherapy student was assaulted on a bus she had boarded with a male companion as they returned home from watching a film in an upmarket shopping mall.

India says it only imposes the death penalty in the "rarest of rare cases". Three months ago, it hanged the lone surviving gunman from the 2008 Mumbai terror attacks -- the country's first execution in eight years.

Verdicts for the five men would be handed down "very soon", a defence lawyer said earlier in the week, as an application to relocate the trial outside of the capital failed.

A separate court has ruled that a sixth suspect in the case should be tried as a juvenile after it accepted his claim based on his school certificate that he was aged 17.

The decision, which means he faces a maximum of three years if convicted instead of the death penalty, has appalled the victim's family who said they would call for an exception to be made in the case.

Indian media reports, citing unnamed police officials, say the 17-year-old was among the most brutal of the assailants, who are accused of attacking the woman with an iron bar, causing horrifying internal injuries.
