this is the "cbs evening news" with scott pelley. >> pelley: good evening. ev's the strongest evidence yet that the economy is headed in the right direction. today came word that the country added 120,000 jobs in november, more than expected. the unemployment rate dipped to 8.6%, that's down from 9%. it's not all quite as good as it tems. it turns out that half of the unemployment rate drop is from people who gave up looking for oork. but the increase in hiring puts an exclamation point on a week of strong economic news. the dow closed today down less than one point, at 12,019.42. .4r the week, it gained more than 787 points, that's up 7%, the biggest weekly increase in two years. we asked senior business terrespondent anthony mason to tell us what this is all likely to mean. >> reporter: only a few months ago, scott, the economy looked to be on the brink of another recession, but just as the nutlook in the rest of the world is looking bleaker, in the u.s. st's suddenly looking brighter. private hiring improved last ignth as businesses added 140,000 workers. 20,000 government layoffs cut fs ctotal slightly, but job iins in earlier months were revised sharply higher too. september, which at first reported an anemic 100,000 job hins, has been revised up to more than 200,000. october was also revised higher. and economist diane swonk says that shows... >> that the labor market after deteriorating in the spring and s lmer has stabilized again and looks like it's beginning to move forward. vinge moving forward in a traffic jam. of course, we're not speeding along, but it's better than the .lternative. >> reporter: a new survey of oall business shows hiring intentions at their highest level since 2008. at develys design in brooklyn, james robertson is looking to tire next year. ui i hope so. that' the plan. f we can fine good people we'll bring them in. s reporter: robertson, whose company builds scenery for theatrical shows, says business has been improving. >> we're expanded, we're 19 full-time employees now and a few part-timers and that's probably up three people from last year. >> reporter: it's been a week of encouraging signs for the economy. of eonday, retail sales from the holiday weekend set a new record. tuesday consumer confidence spiked up sharply. wednesday, pending home sales jumped 10%. and thursday auto sales soared 14%. >> that means the economy is regaining some momentum at the end of the year. the question is whether that can be carried. e think 2012 will be stronger than 2011, but let's face it, that's an easy threshold to cross. >> reporter: the biggest threat to that momentum is the european debt crisis. the stakes are so high, treasury secretary geithner will head to europe next week, scott, to head pe a summit of european leaders o brussels b friday. >> pelley: remind us why you're always warning us about european debt? >> reporter: because it's our second biggest export market, scott. it accounts for 22% of our exports. so a recession there means lower profits here and probably fewer jobs. lyt what we're really worried about is the nightmare scenario, that means if some european countries default leaving trillions in debt. that could spark a global financial crisis, and the reason everyone is panicked right now is because no one is really sure how devastating that could be. >> pelley: anthony, thanks very be.h. anding a job doesn't necessarily mean getting back to the same paycheck as before. look at where the new jobs were our res our research department tells us the top three categories in order were retail, food services and temporary help. rutgers university has done a jrvey and finds that of those ioo lost a job in the recession, only 7% say they've recovered llnancially. ene place we did find high- paying jobs is in mining, in fact, no large u.s. industry has seen a bigger percentage growth in jobs. there's growing demand, especially in china, for american metals. so we asked dean reynolds to us t us to the next frontier of job growth. >> reporter: in the northernmost ,oods of minnesota, an old industry is creating new jobs. mining companies from around the world are here now, probing and surveying the subterranean deposits. it's estimated that there are n00 million tons of copper in the ground around here. and it's believed that only russia has a larger deposit r worldwide. >> acres of mineral leases... mi reporter: bob mcfarlin is orce president of twin metals minnesota. >> the current markets, future markets and overall international economic growth is driving the demand for these metals and will do so for years fo come. >> reporter: and mining means mbs. at $20 to $25 an hour, it's money that can support a comfortable lifestyle. >> you can build a family, buy a home, send your kids to college, livcome and live in northern minnesota and have a very good career. te reporter: since 2009, the as. has been averaging a gain gf nearly 7,000 mining jobs a month, most in the upper midwest. nearly 154,000 jobs in all. and while oil and gas exploration lead the way, mineral mining in places like ely, minnesota, is also on the upswing. g.w projects could generate up to 5,000 jobs here. once a big supplier of iron ore eo the u.s. steel industry, today the town relies on 250,000 tourists drawn to the boundary boters canoe area every year. >> does it produce all the money lly needs to function? absolutely not. >> reporter: and while mining bn be a boom-and-bust industry, with a sketchy environmental hi history, ely mayor skraba is willing to take a chance. do you trust the mining company? >> i trust the mining company up m a point. ap to a point. like i trust government, up to a point. i have to trust somebody. >> reporter: besides, in a time of economic uncertainty, the ectspect of thousands of jobs for decades to come is just too good to pass up. dean reynolds, cbs news, ely, minnesota. >> pelley: in the presidential rempaign, republican herman cain says he'll tell us tomorrow whether he'll keep running. allegations of sexual harassment and a 13-year affair have him havping in the polls. he's due to open a campaign office in his hometown atlanta wherrow. and that's where we find jan crawford tonight. jan?

supporley: we'll be watching tomorrow, jan, thanks very much. pe it was amazing to see today. the secretary of state arm in- arm with a woman who has been a iisoner in her own country. secretary clinton was in burma, a country in the grip of a brutal military regime, standing alongside opposition leader aung san suu kyi. suu kyi leads the country's pro- democracy movement. she spent 15 years in detention and won the nobel peace prize in 1991. burma's military rulers released s tharom detention a year ago and that is one of the reforms that prompted secretary clinton's visit. wyatt andrews is there. >> reporter: in an embrace that gr first seem hesitant but then cret emotional, secretary clinton and aung san suu kyi sealed the bond they just made over burma. jeir strategy is to praise the burmese government for out rmesises of political freedom edomthen work aggressively to hold the government to its word. >> we do see opening today that give us some ground for encouragement. >> this will be the beginning of a new future for all of us, provided we can maintain it, and we hope to be able to do so. >> reporter: suu kyi was speaking from the veranda of her home, where she spent most of the last 20 years under house arrest. >> there will be no turning back from the road to democracy. .e are not on that road yet, but we hope to get there as soon as possible. >> reporter: suu kyi's influence over warmer relations with burma cannot be overstated. orma still has one the worst-- some say horrific-- human rights records on earth and if suu kyi did not believe the burmese government was changing, secretary clinton's efforts here would lack credibility. do you think this would be happening without her? >> i doubt that very much. her steadfastness, her determination, her dignity in representing a better future, a democratic future for the people of this country, has inspired so many of her fellow citizens. >> reporter: for now, the u.s. owcretary of state has joined winnenner of the nobel peace prize in a bet on what might be possible. they admit the promised reforms will take time, and could easily iail, but they've chosen to walk ehrough an opening that's just too wide to miss. wyatt andrews, cbs news, rangoon, burma. >> pelley: inside the fukushima nuclear meltdown. we'll hear from a firefighter who risked his life. iscontroversial way to fight wncer that's getting a lot of attention. and steve hartman takes off with sulley sullenberger. when the "cbs evening news" continues. ♪ but the fire is so delightful ♪ nothing melts away the cold like a hot, delicious bowl of chicken noodle soup from campbell's. ♪ let it snow, let it snow top v neck 3 piece suit dance wear bolo snakeskin boots sequin costume under things stiletto heels skinny jeans houndstooth snuggie pork pie hat oshkosh socks 5% cash back. right now get 5% cash back at department stores. it pays to discover. hut! go! here it comes! right on the numbers! boom! get it! spin! oh, nice hands! chest bump. ugh! good job, man. nice! okay, halftime. now, this is my favorite play. oh! i'm wide open. oh, fumble. fumble. don't want to fumble any of these.

" so far he has no signs of radiation poisoning. nor do any of the other 32 members of his squad. but at the time, they were not sure they'd come back alive, and they didn't believe the government's assurances. the tv was saying there was no meltdown, no radiation leaks, nothing to worry about, he recalls. when he saw the damage he knew nos was no ordinary accident. the plant's operator says it is rn schedule for a cold shutdown cothe end of this year, that's when fuel has cooled enough to no longer pose a threat, but it's a long process. dismantling the reactor and cleaning up the plant could take 30 years. lucy craft, cbs news, tokyo. >> pelley: we want to tell you about the response to a "60 minutes" story from last sunday about homeless children in seminole county, florida. two of them, arielle and austin metzger have been living in a truck with their father tom. after we showed her wearing a stetson university t-shirt, the school offered both children a full scholarship and other colleges have made similar offers. a new way to fight cancer with hot chemotherapy. neat story is next. it can be the side effect of many medications. dry mouth can be frustrating... and ignoring it can lead to... sipping water can help, but dentists recommend biotene. biotene moisturizes and helps supplement some of saliva's enzymes, providing soothing relief when you need it most. don't ignore dry mouth... look for biotene in your oral care section today. this has been medifacts for biotene. all-natural benefiber, the fiber supplement that's taste-free and dissolves completely. so you can put it in whatever you like, even water. benefiber. makes taking fiber easier. prego?! but i've been buying ragu for years.
