Iran Says It Has Found New Uranium Deposits





DUBAI, United Arab Emirates (Reuters) — Days before resuming talks over its disputed nuclear program, Iran said Saturday that it had found significant new deposits of raw uranium and identified sites for 16 more nuclear power stations.




The state news agency IRNA quoted a report by the Atomic Energy Organization of Iran, which said that the reserves were discovered in northern and southern coastal areas and had tripled the amount outlined in previous estimates.


There was no independent confirmation. Western experts had previously thought that Iran, with few uranium mines of its own, might be close to exhausting its supply of raw uranium.


“We have discovered new sources of uranium in the country, and we will put them to use in the near future,” Fereydoun Abbasi-Davani, head of the Atomic Energy Organization, was quoted as saying at Iran’s annual nuclear industry conference.


The timing of the announcement suggested that Iran, by talking up its reserves and nuclear ambitions, may hope to strengthen its negotiating hand at talks in Kazakhstan on Tuesday with the United States, Russia, China, Britain, France and Germany.


Diplomats say the six powers are willing to offer Iran some relief from international sanctions if it agrees to curb its production of higher-grade enriched uranium.


The West says Iran’s enrichment of uranium to a purity of 20 percent demonstrates its intent to develop a nuclear weapons ability, an allegation the Islamic republic denies.


The enriched uranium required for use in nuclear reactors or weapons is produced in centrifuges that spin uranium hexafluoride gas at high speeds. The gas is derived from yellow cake, a concentrate from uranium ore found in mines.


Iran’s raw uranium reserves now total around 4,400 tons, including discoveries over the past 18 months, IRNA quoted the report as saying.


In another sign that Iran is intent on pushing forward with its nuclear ambitions, the report also said that 16 sites had been identified for the construction of nuclear power stations. It did not specify the exact locations but said they included coastal areas of the Persian Gulf, the Gulf of Oman, Khuzestan Province and the Caspian Sea.


The Iranian authorities have long announced their desire to build more nuclear power plants for electricity production. Only one currently exists, in the southern city of Bushehr, and it has suffered several shutdowns in recent months.


The announcements could further complicate the search for a breakthrough in Kazakhstan, after three unsuccessful rounds of talks between the sides in 2012.


“We are meeting all of our obligations under the Nuclear Nonproliferation Treaty, and we should be able to benefit from our rights,” Saeed Jalili, Iran’s chief nuclear negotiator, was quoted as saying at the conference on Saturday. “We don’t accept more responsibilities and less rights.”


In what Washington has called a provocative move, Iran is also installing new-generation centrifuges, capable of producing enriched uranium much faster, at a site in Natanz in the center of the country.


Western diplomats say the six powers will reiterate demands for the suspension of uranium enrichment to a purity of 20 percent, the closing of Iran’s Fordo enrichment plant, increased access for International Atomic Energy Agency inspectors and an agreement to address concerns on existing uranium stockpiles.


In return, the latest embargoes on gold and metals trading with Iran would be lifted. Iran has criticized the offer and says its rights need to be fully recognized.


If the West wants to start constructive talks with Tehran, “It needs to present a valid proposal,” Mr. Jalili said. In a statement issued before the Iranian announcement, the German foreign minister, Guido Westerwelle, said the six-power group wanted to enter a “substantial negotiation process” over Tehran’s nuclear program.


The talks in Kazakhstan “are a chance which I hope Iran takes,” he said.

FDA approves new targeted breast cancer drug


WASHINGTON (AP) — The Food and Drug Administration has approved a first-of-a-kind breast cancer medication that targets tumor cells while sparing healthy ones.


The drug Kadcyla from Roche combines the established drug Herceptin with a powerful chemotherapy drug and a third chemical linking the medicines together. The chemical keeps the cocktail intact until it binds to a cancer cell, delivering a potent dose of anti-tumor poison.


Cancer researchers say the drug is an important step forward because it delivers more medication while reducing the unpleasant side effects of chemotherapy.


"This antibody goes seeking out the tumor cells, gets internalized and then explodes them from within. So it's very kind and gentle on the patients — there's no hair loss, no nausea, no vomiting," said Dr. Melody Cobleigh of Rush University Medical Center. "It's a revolutionary way of treating cancer."


Cobleigh helped conduct the key studies of the drug at the Chicago facility.


The FDA approved the new treatment for about 20 percent of breast cancer patients with a form of the disease that is typically more aggressive and less responsive to hormone therapy. These patients have tumors that overproduce a protein known as HER-2. Breast cancer is the second most deadly form of cancer in U.S. women, and is expected to kill more than 39,000 Americans this year, according to the National Cancer Institute.


The approval will help Roche's Genentech unit build on the blockbuster success of Herceptin, which has long dominated the breast cancer marketplace. The drug had sales of roughly $6 billion last year.


Genentech said Friday that Kadcyla will cost $9,800 per month, compared to $4,500 per month for regular Herceptin. The company estimates a full course of Kadcyla, about nine months of medicine, will cost $94,000.


FDA scientists said they approved the drug based on company studies showing Kadcyla delayed the progression of breast cancer by several months. Researchers reported last year that patients treated with the drug lived 9.6 months before death or the spread of their disease, compared with a little more than six months for patients treated with two other standard drugs, Tykerb and Xeloda.


Overall, patients taking Kadcyla lived about 2.6 years, compared with 2 years for patients taking the other drugs.


FDA specifically approved the drug for patients with advanced breast cancer who have already been treated with Herceptin and taxane, a widely used chemotherapy drug. Doctors are not required to follow FDA prescribing guidelines, and cancer researchers say the drug could have great potential in patients with earlier forms of breast cancer


Kadcyla will carry a boxed warning, the most severe type, alerting doctors and patients that the drug can cause liver toxicity, heart problems and potentially death. The drug can also cause severe birth defects and should not be used by pregnant women.


Kadcyla was developed by South San Francisco-based Genentech using drug-binding technology licensed from Waltham, Mass.-based ImmunoGen. The company developed the chemical that keeps the drug cocktail together and is scheduled to receive a $10.5 million payment from Genentech on the FDA decision. The company will also receive additional royalties on the drug's sales.


Shares of ImmunoGen Inc. rose 2 cents to $14.32 in afternoon trading. The stock has ttraded in a 52-wek range of $10.85 to $18.10.

Torrential Rains Flood Athens and Strand Motorists





ATHENS — Torrential rain of an intensity not seen in decades flooded roads in Athens on Friday, overturning parked cars and stranding dozens of motorists, including a 28-year-old woman who died of what appeared to be a heart attack.




More than six hours of solid rainfall starting at 5 a.m. flooded the streets of the capital, caused two rivers to break their banks and paralyzed public transport, causing traffic chaos as tens of thousands of Athenians sought to reach their offices during the morning rush hour. Two electricity substations were deluged, prompting power cuts, and the fire service was besieged with more than 800 calls from residents with flooded homes and 100 from motorists stuck in floodwaters.


The amount of rain that fell was equal to the average rainfall for the whole month of February, meteorologists said.


A woman found slumped over the wheel of her car in the northern Athens suburb of Halandri died of natural causes, according to doctors at the hospital to which she was taken by rescue workers. Greek news media reported that the woman had died of a heart attack prompted by shock. A few blocks away, residents rescued another woman from her stranded car as muddy floodwaters gushed by, overturning several parked vehicles on the same road.


The rainfall also led to a freak accident at the Parliament building, where a cleaner working on the roof after the rain had stopped stepped through a glass ceiling as she tried to mop up water dripping into the main assembly hall, where lawmakers were to gather for a debate. The woman, who had been wearing a harness, according to parliamentary officials, was left dangling several yards above the deputies’ benches for a few minutes, until a police officer came to her aid.


In another unusual incident, a derelict building in the run-down central district of Aghios Panteleimonas collapsed, apparently because of the force of the sustained downpour. No one was injured after the collapse in the busy neighborhood, one of the poorest and most densely populated in the city center.


Although heavy rain is not unusual during Greece’s brief winter season, an antiquated drainage system in the capital means that streets often remain waterlogged for hours after storms. The scale of Friday’s downpour was unusual, however, with meteorologists referring to the heaviest rainfall in 50 to 60 years in comments on state television.


The Greek government, which is struggling to keep the debt-racked country afloat with billions of euros in rescue loans from foreign creditors, was not able to provide an assessment of the cost of the damage caused to homes, businesses, cars and roads.

Josh Duhamel is ready for fatherhood, but says seeing wife Fergie‘s ultrasound makes the precious expectation of having his own child ever so real.


“It’s very exciting. Seeing that ultrasound is unlike anything you’ve ever seen. You’re like, ‘Wow, it’s mine,’” the actor tells Yahoo! omg! during a press junket for his new film Safe Haven.


The couple, who married in January 2009, announced their happy news via simultaneous Tweets on Monday.


Duhamel, 40, plays a father in his new film, but says time spent with family and friends’ children have opened his eyes to the joys of parenting — even though he knows he has a learning curve ahead.

“I think that I’ve always had an affinity for kids. There’s something about me and kids that just clicks,” explains Duhamel, who is anticipating learning the daddy ropes on the job once the Black Eyed Peas frontwoman delivers their baby.


“I don’t know if it’s because I am a kid, but it does prepare you whenever you’re around them,” he adds. ”I’ve got nieces and nephews and all my friends have kids. All that stuff is a learning experience for when it actually happens, but I don’t think you’re ever truly prepared until it’s your own.”

HP lifts Wall Street, S&P on pace for first weekly loss of year

NEW YORK (Reuters) - Stocks rose on Friday, rebounding off two days of losses as Dow component Hewlett-Packard surged on strong results, but the S&P 500 was on track to end a seven-week-long streak of gains.


The S&P shed 1.9 percent over the previous two sessions, its worst two-day drop since early November, putting the index on pace for its first weekly decline of the year. The retreat was triggered when the Federal Reserve's meeting minutes for January suggested stimulus measures may be halted sooner than thought.


Still, the index is up nearly 6 percent for the year and held the 1,500 support level despite the recent declines, a sign of a positive bias in the market.


"The market is addicted to Fed stimulus and gets withdrawal shakes every time that's threatened, but now we're resuming our course and remain much more attractively valued than other asset classes," said Rex Macey, chief investment officer at Wilmington Trust in Atlanta, Georgia.


Hewlett-Packard Co jumped 9.6 percent to $18.74 as the top boost on both the Dow and S&P 500 after the PC maker's quarterly revenue and forecasts beat expectations. The company cut costs under Chief Executive Meg Whitman's turnaround plan. The S&P technology sector <.splrct> was up 0.8 percent.


The Dow Jones industrial average <.dji> was up 69.41 points, or 0.50 percent, at 13,950.03. The Standard & Poor's 500 Index <.spx> was up 7.74 points, or 0.52 percent, at 1,510.16. The Nasdaq Composite Index <.ixic> was up 18.26 points, or 0.58 percent, at 3,149.75.


For the week, the Dow is off 0.2 percent in its third straight week of slight losses, the S&P is off 0.6 percent and the Nasdaq is off 1.3 percent.


Also buoying tech stocks were gains in semiconductor companies after Marvell Technology Group Ltd forecast results this quarter that were largely above analysts' expectations. Marvell gained market share in the hard-disk drive and flash-storage businesses. The stock rose 2.5 percent to $9.71.


In addition, Texas Instruments Inc raised its dividend by a third and boosted its stock buyback program, lifting shares 5.1 percent to $34.16 while the PHLX semiconductor index <.sox> gained 1.8 percent.


"Dividends growing are another way the market's level is justified, if not especially attractive at these levels," said Macey, who manages about $20 billion in assets.


On the downside, Abercrombie & Fitch dropped 7.6 percent to $45.34 after the clothing retailer reported a drop in fourth-quarter comparable sales, even as its latest quarterly earnings topped estimates.


Insurer American International Group Inc posted fourth-quarter results that beat analysts' expectations. Shares advanced 3 percent to $38.43.


According to Thomson Reuters data through Friday morning, of 439 companies in the S&P 500 that have reported results, 70 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters.


Fourth-quarter earnings for S&P 500 companies are estimated to have risen 6 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Deadly Bombings Hit Southern India City


Mahesh Kumar A/Associated Press


A member of the bomb squad with a sniffer dog arrived at a blast site in Hyderabad on Thursday.







NEW DELHI — Two bombs planted on bicycles killed at least 11 people and wounded 50 in a busy shopping district in the southern India city of Hyderabad at the height of rush hour Thursday night in what officials said may have been a coordinated attack.




Sushil Kumar Shinde, India’s home affairs minister, told journalists in New Delhi that the bicycles had been 150 meters away from each other at the time of the explosions in the Dilsukh Nagar neighborhood, which happened about 10 minutes apart, killing eight at one site and three at the other. The neighborhood is packed with shops, restaurants, theaters and a huge produce market.


Mr. Shinde said the central government had warned state governments that such an attack was planned. “We have had some information for the last two days of such an incident,” he said.


“At this stage it is difficult to say more,” he said. He warned that the death toll may go up.


“This is a dastardly attack, the guilty will not go unpunished,” Prime Minister Manmohan Singh said in a Twitter message.


Hyderabad, one of India’s largest cities and capital of Andhra Pradesh state, is a leading center of the country’s burgeoning pharmaceutical and biotechnology industries.


The blast sites, one near a theater, were soon mobbed by protesters, politicians, reporters and the curious. Television news footage in the hours afterward showed chaotic scenes with some investigators trying to find the remains of explosive devices while huge numbers of people jostled for space around them.


The presence of government officials, who come with enormous entourages and their own police squads, was portrayed by NDTV-News as particularly unhelpful.


“We’ve seen political leaders come into the area and hold press conferences,” the anchor on NDTV said. “That’s the last thing they should be doing.”


Kiran Kumar Reddy, the chief minister of Andhra Pradesh, held a news conference away from the scene late Thursday night and asked people to stay away from the blast areas. Renuka Chowdhury, a leader of the Indian National Congress Party, pleaded with other politicians to stay away as well.


“I really wish politicians would recognize this,” Ms. Chowdhury said.


The money and resources spent on protecting bureaucrats and politicians has become a source of increasing controversy in India, especially in the wake of a highly publicized gang-rape case in December in New Delhi. But Indian politicians, like those elsewhere, often compete with each other to show who is tougher on acts of terrorism and other crimes.


Hyderabad has been the site of frequent bombings in recent years, particularly those using home-made explosives.


In May 2007, 13 people died after a bomb went off at the Mecca Masjid, including some who were killed in clashes between the police and Muslim protesters afterward. In August 2007, a pair of synchronized explosions tore through two popular gathering spots in Hyderabad, killing at least 42 and wounding dozens. Police found and defused 19 more bombs in the hours after the blasts, left at bus stops, theaters, pedestrian bridges and intersections.


In the immediate aftermath of such attacks, a common worry is that one religious community will blame another and attack them. Such sectarian-inspired riots have long plagued India.


Asked in a news conference if he believed that Muslim extremists were to blame for the bicycle blasts, Mr. Shinde said:


“We have to investigate. We should not come to conclusion immediately.”


The country’s prime minister sought to allay anger over the blasts.


“I appeal to the public to remain calm and maintain peace,” he said.


Asaduddin Owaisi, a Muslim member of Parliament from Hyderabad, called the blasts “a cowardly dastardly act.”


“I feel that the priority is to maintain peace,” he said. “Let us not fall pray to rumors.”

Scott and Lauren Sterling Adopt Five Peruvian Siblings

Courtesy The Sterling Family


Two years ago, Scott and Lauren Sterling were sitting in their Blue Springs, Mo., home when an email landed in their inbox with an eye-catching subject line: "Hi, we need a daddy and mommy."

That email, sent a world away from a small orphanage in Pacasmayo, Peru – and written by a fellow member of the couple's church where Scott, 43, is an associate pastor – introduced them to five siblings, then ages 7 to 15, who had lost both parents to tuberculosis about eight years ago. Because the children refused to be split up, the kids' chances of finding new parents were slim.

"Our first thought was, someone rich ought to adopt these beautiful kids," says Lauren, 30, a job recruiter who was already a mom to daughter Laney, now 3, and stepmom to Logan, 19, Scott's daughter from a previous marriage. "But over the next few months, we realized, why not us?"

The Sterlings began a year-long process to legally adopt the five siblings, which involved Skype chats with the kids, reams of paperwork, and $20,000 raised by the Sterlings' church to help with adoption fees. "It's very unusual to find a family willing to take in so many siblings," says Pat Baldwin, director of international programs at Villa Hope, which oversaw the adoption. "What the Sterlings have done is a true act of love.

In Nov. 2012, the Sterlings flew down to the orphanage to meet Yhonson, now 17, Gerson, 15, Betsi, 12, Joel, 11, and Sibila, 9, in person for the first time and to bring them back to the States.

"The girls came running to us from a distance and jumped into Scott's arms," recalls Lauren. Adds Yhonson, who speaks limited English: "We were so happy. It was very emotional. We waited so long to be together."

The new family returned to Missouri just a few days after Christmas and were greeted by friends and neighbors who had stocked the Sterlings' kitchen with food, repainted their bedrooms, and set up a Christmas tree loaded with presents for the kids.

"Our home is now a mixture of Spanish, English and Spanglish thrown in and we use Google Translate a lot," says Lauren. "People say these kids are lucky to have us, but we're the ones who're lucky to have them."

Flu shot did poor job against worst bug in seniors


ATLANTA (AP) — For those 65 and older, this season's flu shot is only 9 percent effective against the most common and dangerous flu bug, according to a startling new government report.


Flu vaccine tends to protect younger people better than older ones and never works as well as other kinds of vaccines. But experts say the preliminary results for seniors are disappointing and highlight the need for a better vaccine.


For all age groups, the vaccine's effectiveness is moderate at 56 percent, which is nearly as well as other flu seasons, the Centers for Disease Control and Prevention said Thursday.


For those 65 and older, it is 27 percent effective against the three strains in the vaccine, the lowest in about a decade but not far below from what's expected. But the vaccine did a particularly poor job of protecting older people against the harshest flu strain, which is causing most of the illnesses this year. CDC officials say it's not clear why.


Vaccinations are now recommended for anyone over 6 months, and health officials stress that some vaccine protection is better than none at all. While it's likely that older people who were vaccinated are still getting sick, many of them may be getting less severe symptoms.


"Year in and year out, the vaccine is the best protection we have," said CDC flu expert Dr. Joseph Bresee.


To be sure, the preliminary data for seniors is less than definitive. It is based on fewer than 300 people scattered among five states.


But it will no doubt surprise many people that the effectiveness is that low, said Michael Osterholm, a University of Minnesota infectious disease expert who has tried to draw attention to the need for a more effective flu vaccine.


Among infectious diseases, flu is considered one of the nation's leading killers. On average, about 24,000 Americans die each flu season, according to the CDC.


This flu season started in early December, a month earlier than usual, and peaked by the end of year. Older people are most vulnerable to flu and its complications, and the nation has seen some of the highest hospitalization rates for people 65 and older in a decade.


Flu viruses tend to mutate more quickly than others, and it's not unusual for multiple strains to be spreading at the same time. A new vaccine is formulated each year targeting the three strains expected to be the major threats. But that involves guesswork.


Because of these challenges, scientists tend to set a lower bar for flu vaccine. While childhood vaccines against diseases like measles are expected to be 90 or 95 percent effective, a flu vaccine that's 60 to 70 percent effective in the U.S. is considered pretty good.


By that standard, this year's vaccine is OK. The 56 percent effectiveness figure means people have a 56 percent lower chance of winding up at the doctor for treatment of flu symptoms.


For seniors, a flu vaccine is considered pretty good if it's in the 30 to 40 percent range, said Dr. Arnold Monto, a University of Michigan flu expert.


Older people have weaker immune systems that don't respond as well to flu shots. That's why a high-dose version was recently made available for those 65 and older. The new study was too small to show whether that made a difference this year.


The CDC estimates are based on about 2,700 people who got sick in December and January. The researchers traced back to see who had gotten flu shots and who hadn't. An earlier study put the vaccine's overall effectiveness slightly higher, at 62 percent.


The CDC's Bresee said there's a danger in providing preliminary results because it may result in people doubting — or skipping — flu shots. But the data was released to warn older people who got shots that they may still get sick and shouldn't ignore any serious flu-like symptoms, he said.


The new data highlights an evolution in how experts are evaluating flu vaccine effectiveness. For years, it was believed that if the viruses in the vaccine matched the ones spreading around the country, then the vaccine would be effective. This year's shot was a good match to the bugs going around this winter, including the harsher H3N2 that tends to make people sicker.


But the season proved to be a moderately severe one, with many illnesses occurring in people who'd been vaccinated.
