captioning sponsored by cbs this is the "cbs evening news" with scott pelley. >> pelley: good evening. today, general motors linked seven more deaths to a faulty ignition switch, and it nearly doubled the number of cars it's recalling, from the 780,000 announced earlier this month, to nearly 1.4 million. g.m. also said today the ignition switch is now tied 31 crashes in which 13 people were killed. right after the initial recall, cbs ws tracked down a g.m. service bulletin that showed the carmaker had known about problems with the switch for nearly a decade. jeff glor has the new developments tonight. >> reporter: this crash of a chevy cobalt in wisconsin in 2006, which killed two teenaged girls, is part of the growing list of recalled vehicles. margie beskau lost her 15-year-old daughter, amy. >> they knew something was wrong

with the car before the accident. i just don't understand how they can knowingly put these cars out and still let people drive them. this is my child. this is my baby girl. >> reporter: earlier this month, general motors recalled the 2005-2007-chevy cobalts and the 2007 pontiac g-5s. today they add five new models, two three-2007 saturn ions, the 2006-2007, hhr, and saturn sky, and 2005-2007, pontiac pursuits sold in canada. >> g.m. did it because they had no other choice. >> reporter: clarence ditlow runs the center for auto safety. >> g.m. is just cutting the losses. it's doing the right thing. it will save lives but the issue is why were 13 lives lost? >> reporter: g.m. says a heavy key ring or sudden jar category

switch the car off. that means no engine power, no power steering, no power brakes, and the airbags don't work. g.m. filed this updated timeline with federal investigators. 2004: g.m. became aware of at least one incident involving a chevy cobalt. an inquiry was opened but after consideration of the lead time required, cost, and effectiveness of the solution, it is closed with no action. 2005: "new field reports of engines losing power." a service bull tifns issued to dealers in case customers complained saying, "there's the potential for the driver to inadvertently turn off the ignition. the concern is it more likely to occur if the driver is short and has a large and/or heavy key chain but no recall was issued. 2007, a g.m. engineer began an investigation. new incidents of airbags not deploying or discovered. 2010, g.m. discontinued production of the cobalt. >> this is going to go down as one of the top 10 worst defects

recalls ever because it was covered up. >> reporter: last week, when we asked g.m. why the recall did not include additional models announced today, we were told, "we have no confirmed reports of incidents involving nondeployment of frontal airbags occurring on on these other investigation under the conditions of the cobalt 5 recall." today, g.m. told us, want process to employ examine this phenomenon was not as detailed as it should have been." g.m., which says it will fix the defect, is facing a fine graffiti. but because people died they are also potentially looking at a criminal penalty. >> pelley: jeff, thanks very much. a new blast of arctic air is driving across the northern united states. the mercury hit 27 beploa zero in longville, minnesota. adding to the weather problems--

ice cams. dean reynolds has more about them. >> reporter: considerable damage has already been done in tippecanoe county, indiana, where buckling ice ran wild, literally plowing trees and wrecking property. these pictures from ohio last week captured the speed and strength of an ice jam on the move. and many in the region are now fearing a similar fate. i'm standing on the shoreline of the river, and all of this ice in front of me has come up over the bank and threatens to keep on coming. >> this is probably 12 feet from the river's edge, and look at it. it's like just mass destruction. you can't stop the ice. >> reporter: steve highbaugh has lived along the river? illinois for a quarter century. you have a danger from pulverizing but also then follow-on flooding? >> correct. >> reporter: how does that make you feel? >> well, not as good as i feel in july, that's for sure. >> reporter: the combination

of the thaw and rain late last week got the ice going. but even when appearing motionless, car-sized chunks are generating dangerous pressure on infrastructure, and the waiter underneath could quickly reroute sideways to get around the jam, caution flooding. this unusual? >> yes, sir. this is not something you see every year. >> reporter: trent thompson is chief of operations for the illinois emergency management agency. >> we are looking at something that looks very still and very calm right now, but any-- at any time it could cause massive problems with where they break up and start flowing. >> reporter: tonight, scott, the residents along this river are watching it closely, knowing that the next move it makes could force them from their homes. >> pelley: that's quite a sight, deep, thanks very much. now, as for what's in the forecast, chief meteorologist eric fisher at our cbs boston station wbz tells us that the arctic air will be dropping south over the next three days. by thursday, lows will be in the

teens and the 20s in texas, and across the deep south on friday. the governor of arizona is feeling heat tonight over a controversial bill that pits religious rights against the rights of gay americans. jan brewer must decide by saturday whether to sign the bill or kill it. jan crawford has our story. >> reporter: scott koheler is making a statement. >> we are open to everybody. we're not discriminatory in any way, shape, or form. >> reporter: the arizona sign shop owner has put that message on thousands of these signs which now are in storefront windows across the phoenix area. it's all part of a ground swell of opposition to a proposed state law that would make it easier for businesses to deny service based on religious beliefs. critics say the bill is a license for discrimination against gays and lesbians. >> i think if this bill is passed into law in the state of arizona, that a lot ofut people are going t see arizona

differently. and i just think in general it's bad for business in arizona. it gives us a black eye. >> reporter: supporters say the legislation was designed to protect small businesses, like wedding photographers and bakeries, who may have religious objections to same-sex marriages. cathi herrod of the center for arizona policy helped craft the bill. >> 1062 is about one thing and one thing only, that americans, arizonaians should be free to live and work according to their faith. >> reporter: but just five days after the bill passed, there's intense pressure on governor jan brewer to veto it. national corporations doing business in arizona are calling for a veto, as is the arizona super bowl host committee which says the law could jeopardize planlz for the state to host next year's super bowl. now, yesterday, three republican state senators who actually voted for the bill sent brewer a letter urging her to veto it. the governor said she's going to decide by friday, and, scott, political insiders say they think a veto is likely.

>> pelley: we'll keep following this, jan, thank you very much. now, along with the dollar and euro there is a new currence called the bitcoins. you can't fut in your pocket. it trades only on the internet, and today one of the biggest bitcoins exchanges based in tokyo went bust after it was revealed that hundreds of millions of dollars worth of bitcoins were missing. we asked anthony mason to explain all this. >> reporter: in a manhattan park last fail air, small crowd gathered to buy and sell a new unregulated currency. on their smart phones they traded a digital money called bitcoinses. you're a big believener this currency. >> i'm a big believer in bitcoins. >> barry bill cert is sce of second market, an online exchange for nawnl traditional investments. >> i think it's a global currency like the u.s. dollar or euro and i think it's a great

money transfer network like western union. >> reporter: created by an anonymous computer programmer in 2009, bitcoins exists only as a code in a computer. a bitcoin can be sent directly from one owner's digital wallet to another anywhere in the world without going through financial institutions. >> i believe it's a game changer. i believe bitcoin is as big as the internet itself, changing the way people think about money, change the way people send money, spend money is as big as the internet. >> reporter: retail shops have started accepting bitcoins. this restaurant in cambridge, massachusetts, honors them because customers like japhet stephens asked for it. >> i do see it as the new gold of the future. >> reporter: how easy is it to exk? >> there are exchanges all around the world roemer it's been a risky investment. the value of a bitcoin fluctuates on demand. a year ago one costed about $30,

and by december it soared to $1,000. but today the price plummeted below $500. and law enforcement fears the currency is ideal for criminals. last october, the f.b.i. shut down the web site silkroadalled it was a one-stop shop for drugs and weapons used through bitted coins. >> i'm sure it has been used but so have u.s. dollars and diamonds and gold over time. >> reporter: with the biggest bitcoin exchange planning to file for bankruptcy, silbert said he is can thing with major bankbanks and regulators. >> pelley: anthony, thanks very much. here's a rare picture that we received. the president of the united states meeting today with the speaker of the house. it is their first one-on-one meeting in the oval office since december of 2012. we're told that they agreed that there is much work to be done,

though in this election year, there's considerable doubt that they will do it. president obama found another opponent on the phone today. he called hamid karzai, the president of afghanistan, and gave him an ultimatum concerning u.s. troops there. david martin has been looking into this. >> reporter: you could say president obama finally gave up on president karzai today. he called him to say that since the notoriously difficult afghan president would not sign a troop agreement, there was nothing for it but to start planning for pulling all american forces out by the end of this year. the pentagon was already planning for the so-called zero option, but it was the first time karzai had heard it officially from the president of the united states. there are currently 34,000 american troops in afghanistan, and the top commander, general joseph dunford, has recommended keeping 10,000 there for two years after 2014 if the

government of afghanistan first signs a security agreement. president obama left open the possibility of signing that agreement with karzai's successor after afghanistan holds elections this spring. but he warned-- the longer it takes, the smaller the number of u.s. troops that stay behind is likely to be. the president's phone call may not change karzai's mind. he has refused to sign any agreement which allows u.s. troops to continue their raids on afghan homes, but it will surely affect thinking elsewhere in afghanistan, where the army still depends on american support to carry out operations against the taliban. a senior pakistani official predicted if all u.s. troops were to pull out, 30% of the afghan army would dessert. and it will affect thinking among nato allies, which also have troops in afghanistan. perhaps the most telling sign president obama has given up on karzai is that today's phone call was the first time the two men had talked since june of last year.

days of meetings about a controversial medical procedure that critics believe could lead to designer babies. dr. jon lapook has been looking into this for us. jon. >> reporter: scott, one of the issues scientists will discuss at this meeting is how clinical trials might be conducted. it's controversial because in addition to the d.n.a. of the mother and the father, material from a third person is used in the prosprocess. the vast majority of a cell's d.n.a. is located in the nucleus, but a tiny fraction is outside the nucleus in structures called mitochondrial. these mitochondrial genes are inherited only from the mother, and in rare cases, can be defective. these defects can cause problems such as blindness, muscle disorders and neurological illness. one proposed technique would work this we-- a woman's nucleus is removed from her egg, leaving behind her unhealthy might chondria. her nucleus containing the majority of the genes replacing

it in the donor egg. >> pelley: so what are the concerns? >> reporter: scott, there are technical issues. how do you make this safe and effective. but then there are ethical issues raised. you're starting off with a technique meant to prevent devastating illnesses but there is concern it could be used for designer babies. other qualities parents find desirable. we are way off technically from being able to do this, but that's the fear. >> pelley: jon, thank you very much. fascinating. today, the government reported some encouraging news about childhood obesity. 10 years another nearly 14% of preschoolers ages 2-5 were considered obese, but that has nodropped to just over 8%. one reason is children are drinking fewer sugary drinks. a family strikes gold in their backyard. that story is coming up. before those little pieces
