Riots to Protest Death Sentence Enter 3rd Day in Bangladesh

Associated Press

A car burned in Dhaka, Bangladesh, on Saturday. Unrest continued after the leader of an Islamic party was sentenced to death.

DHAKA, Bangladesh (AP) — Demonstrators protesting the death penalty given to an Islamic political party leader clashed with Bangladeshi security forces for a third straight day on Saturday, killing two people and injuring about a dozen, the police said.

Delawar Hossain Sayedee, one of the top leaders of Jamaat-e-Islami, the country’s largest Islamic party, was sentenced to death on Thursday by a war crimes tribunal for atrocities committed during Bangladesh’s 1971 war of separation from Pakistan. The sentence set off rioting across the country, killing at least 46 people, including the two in the latest fighting, the authorities said.

Mr. Sayedee, 73, is the third defendant to be convicted by the tribunal, which was set up in 2010 by Prime Minister Sheikh Hasina’s government. He was accused of involvement in looting and burning villages, raping women and forcing people to convert to Islam.

An additional seven top leaders of Jamaat, including its chief, Matiur Rahman Nizami, are on trial facing war crimes charges.

Jamaat campaigned against Bangladesh’s nine-month war of independence and formed some auxiliary forces to help the Pakistani troops, but it has denied committing atrocities.

Bangladesh says that during the war, three million people were killed, 200,000 women were raped and millions of others were forced to flee the country.

On Saturday, security forces used tear gas to stop Jamaat supporters from smashing vehicles and blocking roads in Chittagong district, the police said. The area is 135 miles southeast of Dhaka, the capital.

Two men were killed and about a dozen were injured in the fighting, a local police official said, speaking on the condition of anonymity because he was not authorized to speak to the news media.

Dhaka’s private television stations, Ekattor TV and Somoy TV, reported that Jamaat supporters had erected roadblocks and attacked the homes of government supporters in some areas.

Jamaat is an ally of Bangladesh’s main opposition party, the Bangladesh Nationalist Party, which is led by former Prime Minister Khaleda Zia, and was a partner in Ms. Zia’s government from 2001 to 2006.

Ms. Zia says the war crimes trials are politically motivated to prosecute the opposition, an allegation the government rejects.

Jamaat and Ms. Zia’s party have called for a three-day nationwide general strike starting on Sunday.

Jen & Justin: Why They Can't Wait to Wed!

By Michelle Tauber

03/02/2013 at 03:00 PM EST

Here's the thing about being Jennifer Aniston and being in love: The universe is invested. On Feb. 24 the star hit the red carpet in scarlet Valentino, her fiancé, Justin Theroux, by her side.

Flashes shimmered, fans roared, and the pair ducked into Hollywood's Dolby Theatre to take in the show. But there, the girl everyone presumes lives next door (who knew we all owned mansions?) was confronted by a friendly but curious employee who boldly asked That Question: Are you pregnant?

"No, I'm not!" replied Aniston, laughing politely. But, "I feel great," she told PEOPLE later that evening. "Wonderful!"

And on the outside? Forget about it. "She looks the greatest she possibly could," says Chris McMillan, her old pal and partner in her new hair-care line Living Proof. "Look at where she is in her life."

There's the man. There's that ring. There's a slate of films and new beauty ventures, renovating a $21 million L.A. estate in hopes of soon "normalizing and nesting," as she recently told PEOPLE, and, yes, planning a wedding.

With her film, based on an Elmore Leonard novel, set to wrap in Connecticut on March 8, "Jen and Justin have a date" set for soon after, says a source close to the actress, noting that the twosome have designed their wedding bands and Aniston has a dress in mind. "It will be a small affair with their closest friends." Likely among them: Aniston BFFs Courteney Cox, Chelsea Handler and Mandy Ingber, all of whom headed to New York to celebrate the actress's 44th birthday at the Greenwich Hotel on Feb. 11.

The bride-to-be "is crazy about Justin and can't wait to be his wife," says the source. "She plans on privately changing her name to
Theroux. She likes the way it sounds and jokes that [Jennifer Theroux] sounds very posh."

WHO: Slight cancer risk after Japan nuke accident

LONDON (AP) — Two years after Japan's nuclear plant disaster, an international team of experts said Thursday that residents of areas hit by the highest doses of radiation face an increased cancer risk so small it probably won't be detectable.

In fact, experts calculated that increase at about 1 extra percentage point added to a Japanese infant's lifetime cancer risk.

"The additional risk is quite small and will probably be hidden by the noise of other (cancer) risks like people's lifestyle choices and statistical fluctuations," said Richard Wakeford of the University of Manchester, one of the authors of the report. "It's more important not to start smoking than having been in Fukushima."

The report was issued by the World Health Organization, which asked scientists to study the health effects of the disaster in Fukushima, a rural farming region.

On March 11, 2011, an earthquake and tsunami knocked out the Fukushima plant's power and cooling systems, causing meltdowns in three reactors and spewing radiation into the surrounding air, soil and water. The most exposed populations were directly under the plumes of radiation in the most affected communities in Fukushima, which is about 150 miles (240 kilometers) north of Tokyo.

In the report, the highest increases in risk are for people exposed as babies to radiation in the most heavily affected areas. Normally in Japan, the lifetime risk of developing cancer of an organ is about 41 percent for men and 29 percent for women. The new report said that for infants in the most heavily exposed areas, the radiation from Fukushima would add about 1 percentage point to those numbers.

Experts had been particularly worried about a spike in thyroid cancer, since radioactive iodine released in nuclear accidents is absorbed by the thyroid, especially in children. After the Chernobyl disaster, about 6,000 children exposed to radiation later developed thyroid cancer because many drank contaminated milk after the accident.

In Japan, dairy radiation levels were closely monitored, but children are not big milk drinkers there.

The WHO report estimated that women exposed as infants to the most radiation after the Fukushima accident would have a 70 percent higher chance of getting thyroid cancer in their lifetimes. But thyroid cancer is extremely rare and one of the most treatable cancers when caught early. A woman's normal lifetime risk of developing it is about 0.75 percent. That number would rise by 0.5 under the calculated increase for women who got the highest radiation doses as infants.

Wakeford said the increase may be so small it will probably not be observable.

For people beyond the most directly affected areas of Fukushima, Wakeford said the projected cancer risk from the radiation dropped dramatically. "The risks to everyone else were just infinitesimal."

David Brenner of Columbia University in New York, an expert on radiation-induced cancers, said that although the risk to individuals is tiny outside the most contaminated areas, some cancers might still result, at least in theory. But they'd be too rare to be detectable in overall cancer rates, he said.

Brenner said the numerical risk estimates in the WHO report were not surprising. He also said they should be considered imprecise because of the difficulty in determining risk from low doses of radiation. He was not connected with the WHO report.

Some experts said it was surprising that any increase in cancer was even predicted.

"On the basis of the radiation doses people have received, there is no reason to think there would be an increase in cancer in the next 50 years," said Wade Allison, an emeritus professor of physics at Oxford University, who also had no role in developing the new report. "The very small increase in cancers means that it's even less than the risk of crossing the road," he said.

WHO acknowledged in its report that it relied on some assumptions that may have resulted in an overestimate of the radiation dose in the general population.

Gerry Thomas, a professor of molecular pathology at Imperial College London, accused the United Nations health agency of hyping the cancer risk.

"It's understandable that WHO wants to err on the side of caution, but telling the Japanese about a barely significant personal risk may not be helpful," she said.

Thomas said the WHO report used inflated estimates of radiation doses and didn't properly take into account Japan's quick evacuation of people from Fukushima.

"This will fuel fears in Japan that could be more dangerous than the physical effects of radiation," she said, noting that people living under stress have higher rates of heart problems, suicide and mental illness.

In Japan, Norio Kanno, the chief of Iitate village, in one of the regions hardest hit by the disaster, harshly criticized the WHO report on Japanese public television channel NHK, describing it as "totally hypothetical."

Many people who remain in Fukushima still fear long-term health risks from the radiation, and some refuse to let their children play outside or eat locally grown food.

Some restrictions have been lifted on a 12-mile (20-kilometer) zone around the nuclear plant. But large sections of land in the area remain off-limits. Many residents aren't expected to be able to return to their homes for years.

Kanno accused the report's authors of exaggerating the cancer risk and stoking fear among residents.

"I'm enraged," he said.

With record highs in sight, stocks face roadblocks

NEW YORK (Reuters) - If Wall Street needs to climb a wall of worry, it will have plenty of opportunity next week.

Major U.S. stock indexes will make another attempt at reaching all-time records, but the fitful pace that has dominated trading is likely to continue. Next Friday's unemployment report and the hefty spending cuts that look like they about to take effect will be at the forefront.

The importance of whether equities can reach and sustain those highs is more than Wall Street's usual fixation on numbers with psychological significance. Breaking through to uncharted territory is seen as a test of investors' faith in the rally.

"It's very significant," said Bucky Hellwig, senior vice president at BB&T Wealth Management in Birmingham, Alabama.

"The thinking is, there's just not enough there for an extended bull run," he said. "If we do break through (record highs), then maybe the charts and price action are telling us there's something better ahead."

Flare-ups in the euro zone's sovereign debt crisis and next Friday's report on the U.S. labor market could jostle the market, though U.S. job indicators have generally been trending in a positive direction.

Small- and mid-cap stocks hit lifetime highs in February. Now the Dow Jones industrial average <.dji> and the S&P 500 <.spx> are racing each other to the top. The Dow, made up of 30 stocks, is about 75 points - less than 1 percent - away from its record close of 14,164.53, which it hit on October 9, 2007. The broader S&P is still 3 percent away from its closing high of 1,565.15, also reached on October 9, 2007.

The advantage may be in the Dow's court. So far in 2013, it has gained 7.5 percent, beating the S&P 500 by about 1 percent.

THE RALLY AND THE REALITY CHECK

The Dow's relative strength owes much to its unique make-up and calculation, as well as to investors' recent preference for buying value stocks likely to generate steady reliable gains, rather than growth stocks.

But the more defensive stance illustrates how stock buyers are getting concerned about this year's rally. While investors don't want to miss out on gains, they're picking up companies that are less likely to decline as much as high-flying names - if a market correction comes.

The Russell Value Index <.rav> is up 7.6 percent for the year so far, outpacing the Russell Growth Index's <.rag> 5.7 percent rise. Within the realm of the S&P 500, the consumer staples sector led the market in February, gaining 3.1 percent.

There is some concern that growth-oriented names are being eclipsed by defensive bets, said Ryan Detrick, senior technical strategist at Schaeffer's Investment Research in Cincinnati.

"This isn't a be-all and end-all sell signal by any means, but we would feel much more comfortable if some of the more aggressive areas, like technology and small caps, would start to gain some leadership here," Detrick said.

Signs that investors are becoming concerned about the rally's pace is evident in the options market, where the ratio of put activity to call activity has recently shifted in favor of puts, which represent expectations for a stock to fall.

"We are seeing some put hedging in the financials, building up for the past month," said Henry Schwartz, president of options analytics firm Trade Alert in New York.

The put-to-call ratio representing an aggregate of about 562 financial stocks is 1:1, when normally, calls should be outnumbering puts.

Investors have no shortage of reasons to crave the relative safety of blue chips and defensive stocks. Although markets have mostly looked past uncertainty over Washington's plans to cut the deficit, fiscal policy negotiations still pose a risk to equities.

The $85 billion in spending cuts set to begin on Friday is expected to slow economic growth this year if policymakers do not reach a new deal. Markets so far have held firm despite the wrangling in Washington, but tangible economic effects could pinch stock prices going forward.

The International Monetary Fund warned that full implementation of the cuts would probably take at least 0.5 percentage point off U.S. growth this year.

EASY MONEY AND TEPID HIRING

Investors will also take in a round of economic data at a time when concerns are percolating that the market is being pushed up less by fundamentals and more by loose monetary policy around the world.

The main economic event will be Friday's non-farm payrolls report for February. The U.S. economy is expected to have added 160,000 jobs last month, only a tad higher than in January, in a sign the labor market is healing at a slow pace. The U.S. unemployment rate is forecast to hold steady at 7.9 percent.

While lackluster data has been a catalyst in the past for stock market gains as investors bet it would ensure continued stimulus from the Federal Reserve, that sentiment may be wearing thin.

Markets stumbled last week following worries that the Fed might wind down its quantitative easing program sooner than expected.

"It shows the underpinning of the market is being driven at this point by monetary policy," Hellwig said.

With investors questioning what is behind the rally, it will make a run to record highs even more significant, Hellwig added.

"There's smart people that are in the bull camp and the bear camp and the muddle-through camp," Hellwig said. "The fact that you can statistically, using historical evidence, make a case for going higher, lower, or staying the same makes this number very important this time around."

Leaving North Korea, Rodman Calls Kims ‘Great Leaders’

Jason Mojica/VICE Media, via Associated Press

The North Korean leader, Kim Jong-un, and the former N.B.A. star Dennis Rodman watched an exhibition basketball game in Pyongyang on Thursday.

PYONGYANG, North Korea (AP) — Ending his unexpected round of basketball diplomacy in North Korea on Friday, ex-NBA star Dennis Rodman called leader Kim Jong Un an "awesome guy" and said his father and grandfather were "great leaders" — an assessment that got short shrift from the U.S. government.

Rodman, the highest-profile American to meet Kim since he inherited power from father Kim Jong Il in 2011, watched a basketball game with the authoritarian leader Thursday and later drank and dined on sushi with him.

At Pyongyang's Sunan airport on his way to Beijing, Rodman said it was "amazing" that the North Koreans were "so honest." He added that Kim Jong Il and Kim Il Sung, North Korea's founder, "were great leaders."

"He's proud, his country likes him — not like him, love him, love him," Rodman said of Kim Jong Un. "Guess what, I love him. The guy's really awesome."

At Beijing's airport, Rodman pushed past waiting journalists without saying anything.

Rodman's visit to North Korea began Monday and took place amid tension between Washington and Pyongyang. North Korea conducted an underground nuclear test just two weeks ago, making clear the provocative act was a warning to the United States to drop what it considers a "hostile" policy toward the North.

The State Department on Friday distanced itself from Rodman's visit and his praise for Kim, saying he doesn't represent the United States.

"The North Korean regime has a horrific human rights record, quite possibly the worst human rights situation in the world," spokesman Patrick Ventrell told reporters in Washington. He accused the regime of depriving their people of food, shelter, water and maintaining prison gulags.

Ventrell also took aim at Pyongyang for its grand treatment of the visiting basketball stars.

"Clearly you've got the regime spending money to wine and dine foreign visitors, when they should be feeding their own people," he said.

Rodman traveled to Pyongyang with three members of the professional Harlem Globetrotters basketball team, VICE correspondent Ryan Duffy and a production crew to shoot an episode on North Korea for a new weekly HBO series.

Kim, a diehard basketball fan, told the former Detroit Pistons and Chicago Bulls star that he hoped the visit would break the ice between the United States and North Korea, said Shane Smith, founder of the New York-based VICE media company.

Dressed in a blue Mao suit, Kim laughed and slapped his hands on a table during the game at Jong Ju Yong Gymnasium as he sat nearly knee to knee with Rodman. Rodman, the man who once turned up in a wedding dress to promote his autobiography, wore a dark suit and dark sunglasses, but still had on his nose rings and other piercings. A can of Coca-Cola sat on the table before him in photos shared with AP by VICE.

Smith, after speaking to the VICE crew in Pyongyang, said Kim and Rodman "bonded" and chatted in English, though Kim primarily spoke in Korean through a translator.

Thursday's game ended in a 110-110 tie, with two Americans playing on each team alongside North Koreans. After the game, Rodman addressed Kim in a speech before a crowd of tens of thousands of North Koreans and told him, "You have a friend for life," VICE spokesman Alex Detrick told AP.

At an "epic feast" later, the leader plied the group with food and drinks and round after round of toasts were made, Duffy said in an email to AP.

Duffy said he invited Kim to visit the United States, a proposal met with hearty laughter from the North Korean leader.

Kim said he hoped sports exchanges would promote "mutual understanding between the people of the two countries," the official Korean Central News Agency said.

Ventrell said the U.S. wanted North Korea to come into line with their international obligations and to stop ballistic missile tests and their nuclear programs. "We're not going to read into this sort of theater one way or another," he said.

North Korea and the U.S. fought on opposite sides of the three-year Korean War, which ended in a truce in 1953. The foes never signed a peace treaty, and do not have diplomatic relations.

Rodman's trip is the second attention-grabbing American visit this year to North Korea. Google's executive chairman, Eric Schmidt, made a four-day trip in January to Pyongyang, but did not meet the North Korean leader.

The Obama administration had frowned on the trip by Schmidt, who was accompanied by former New Mexico Gov. Bill Richardson, but has avoided criticizing Rodman's outing, saying it's about sports.

Valerie Bertinelli Pays Special Tribute to Bonnie Franklin

03/01/2013 at 02:55 PM EST

Bonnie Franklin, who died of pancreatic cancer Friday, and Valerie Bertinelli go back nearly 40 years, to the sitcom One Day at a TIme, on which Franklin played her mother, Ann Romano.

Two years ago the actresses reunited professionally, on Bertinelii's series Hot in Cleveland.

Bertinelli said in a statement Friday: "My heart is breaking. Bonnie has always been one of the most important women in my life and was a second mother to me.

"The years on One Day at a Time were some of the happiest of my life, and along with Pat [Harrington Jr.] and Mackenzie [Phillips] we were a family in every way.

"She taught me how to navigate this business and life itself with grace and humor, and to always be true to yourself. I will miss her terribly."

At Ice Age End, a Smaller Gap in Warming and Carbon Dioxide

A meticulous new analysis of Antarctic ice suggests that the sharp warming that ended the last ice age occurred in lock step with increases of carbon dioxide in the atmosphere, the latest of many indications that the gas is a powerful influence on the earth’s climate.

Previous research had suggested that as the world began to emerge from the depths of the ice age more than 20,000 years ago, warming in Antarctica preceded changes in the global carbon dioxide level by something like 800 years.

That relatively long gap led some climate-change contrarians to assert that rising carbon dioxide levels were essentially irrelevant to the earth’s temperature — a side effect of planetary warming, perhaps, but not the cause.

Mainstream climate scientists have rejected that view and argued that carbon dioxide, while it did not initiate the end of the ice age, played a vital role in the feedback loops that caused a substantial warming.

Still, a long gap between increases of temperature and of carbon dioxide was relatively hard for the scientists to explain. In the political debate in the United States over global warming, the supposed gap has been invoked repeatedly by climate-change contrarians.

In 2007, for example, Al Gore was testifying to Congress about the science in his documentary, “An Inconvenient Truth.” He came under attack by Representative Joe L. Barton, Republican of Texas.

“CO2 levels went up after the temperature rose,” Mr. Barton said, citing a scientific paper from 2001. “The temperature appears to drive CO2, not vice versa. On this point, Mr. Vice President, you’re not just off a little. You’re totally wrong.”

But the paper published online Thursday by the journal Science, together with a string of other recent studies, suggests that Mr. Gore was right all along.

The research was led by Frédéric Parrenin of the University of Grenoble, in France. He and his colleagues took a new stab at sorting out the sequence of events at the close of the last great ice age.

Since the 1980s, scientists have been collecting a climate record from those earlier times by extracting long cylinders of ice from the ice sheets in Greenland and Antarctica.

Air bubbles trapped in the polar ice give direct evidence of the past composition of the atmosphere. And subtle chemical variations in the ice itself give an indication of the local temperature at the time it was formed.

The trouble is that the air bubbles do not get sealed off for hundreds or even thousands of years, as the snow is slowly buried and compressed. Therefore, it is tricky for scientists to put the atmospheric record and the temperature record onto a common time scale.

Early analyses had fairly large error margins. Nonetheless, they produced one of the most striking findings of modern science: an extremely tight association between the temperature and the level of carbon dioxide in the atmosphere. That is consistent with basic physics showing that carbon dioxide is a powerful greenhouse gas.

But in several reconstructions based on ice cores, local temperature increases at the poles appeared to slightly precede global increases of carbon dioxide. In the 2001 paper that Mr. Barton cited, for example, Antarctic temperature appeared to lead global carbon dioxide levels by 800 years, give or take 600 years.

Using high-precision chemical techniques, Dr. Parrenin and his colleagues have essentially reduced the error margin. Their findings suggest that increases of carbon dioxide lagged temperature increases in Antarctica by no more than about 200 years and may have even preceded the temperature increase.

“It’s a breakthrough in our concept of how past climate evolved,” Dr. Parrenin said in an interview.

It remains to be seen how well the paper will withstand scientific scrutiny. “I’m left with this uneasy feeling that the uncertainties are larger than they claim,” said Eric Steig, a climate scientist at the University of Washington.

Dr. Steig noted that Dr. Parrenin’s paper is the third in recent years to suggest that the gap in the climate records between polar temperature and CO2, if it exists at all, is relatively small. And Jeremy Shakun, a visiting scholar at Harvard, compiled a temperature record for the whole planet, not just Antarctica. He concluded that the carbon dioxide increase preceded the overall planetary warming.

A small gap poses no conceptual problems, scientists said. They have long known that the ice ages are caused by variations in the earth’s orbit around the sun. When an intensification of sunlight initiates the end of an ice age, they believe, carbon dioxide is somehow flushed out of the ocean, causing a big amplification of the initial warming.

That understanding is one of the cornerstones of the scientists’ warning that modern society is running a big risk by burning fossil fuels and pumping enormous quantities of carbon dioxide into the atmosphere.

The level has already jumped 41 percent since the Industrial Revolution began in the 18th century, and given the weakness of global efforts to control emissions, scientists say it could eventually double or triple. Even at the current concentration, the evidence suggests that increases in sea level of 25 feet or more may have already become inevitable, albeit over a long period.

“We’re just entering a new era in earth’s history,” Dr. Shakun said. “It will be an unrecognizable new planet in the future. I think the only question is, exactly how fast does that transformation happen?”

Michelle Williams Was 'Not Ready' to Commit to Jason Segel: Source

From the outside, it seemed as though Michelle Williams couldn't get enough of boyfriend Jason Segel. In reality, the actress may not have seen him as forever material.

"She cares a great deal for Jason but is not ready to make a commitment," a source tells PEOPLE. "Maybe if they were together day-to-day, she would have more confidence in a future. But not at this time."

Dating for a year, PEOPLE confirmed on Tuesday that the pair called it quits, citing long distance as the primary reason.

"Jason never got rid of his place in L.A., and Michelle's life with [daughter] Matilda was and has always been in New York," a second source says. "While Jason made every effort to make them a priority in his life – and they were top priority – he still couldn't drop everything and leave his life and career in L.A."

The road to romance has not been an easy one for Williams, 32.

The actress's ex, Heath Ledger, was found dead of an accidental prescription drug overdose in 2008, less than a year after they split. Left to care for their daughter alone, Williams stayed out of the spotlight, but began dating director Spike Jonze for about a year. Following their split, she didn't have a public romance again until Segel, 33, in 2012.

Huge study: 5 mental disorders share genetic links

WASHINGTON (AP) — The largest genetic study of mental illnesses to date finds five major disorders may not look much alike but they share some gene-based risks. The surprising discovery comes in the quest to unravel what causes psychiatric disorders and how to better diagnose and treat them.

The disorders — autism, attention deficit-hyperactivity disorder or ADHD, bipolar disorder, major depressive disorder and schizophrenia — are considered distinct problems. But findings published online Wednesday suggest they're related in some way.

"These disorders that we thought of as quite different may not have such sharp boundaries," said Dr. Jordan Smoller of Massachusetts General Hospital, one of the lead researchers for the international study appearing in The Lancet.

That has implications for learning how to diagnose mental illnesses with the same precision that physical illnesses are diagnosed, said Dr. Bruce Cuthbert of the National Institute on Mental Health, which funded the research.

Consider: Just because someone has chest pain doesn't mean it's a heart attack; doctors have a variety of tests to find out. But there's no blood test for schizophrenia or other mental illnesses. Instead, doctors rely on symptoms agreed upon by experts. Learning the genetic underpinnings of mental illnesses is part of one day knowing if someone's symptoms really are schizophrenia and not something a bit different.

"If we really want to diagnose and treat people effectively, we have to get to these more fine-grained understandings of what's actually going wrong biologically," Cuthbert explained.

Added Mass General's Smoller: "We are still in the early stages of understanding what are the causes of mental illnesses, so these are clues."

The Psychiatric Genomics Consortium, a collaboration of researchers in 19 countries, analyzed the genomes of more than 61,000 people, some with one of the five disorders and some without. They found four regions of the genetic code where variation was linked to all five disorders.

Of particular interest are disruptions in two specific genes that regulate the flow of calcium in brain cells, key to how neurons signal each other. That suggests that this change in a basic brain function could be one early pathway that leaves someone vulnerable to developing these disorders, depending on what else goes wrong.

For patients and their families, the research offers no immediate benefit. These disorders are thought to be caused by a complex mix of numerous genes and other risk factors that range from exposures in the womb to the experiences of daily life.

"There may be many paths to each of these illnesses," Smoller cautioned.

But the study offers a lead in the hunt for psychiatric treatments, said NIMH's Cuthbert. Drugs that affect calcium channels in other parts of the body are used for such conditions as high blood pressure, and scientists could explore whether they'd be useful for psychiatric disorders as well.

The findings make sense, as there is some overlap in the symptoms of the different disorders, he said. People with schizophrenia can have some of the same social withdrawal that's so characteristic of autism, for example. Nor is it uncommon for people to be affected by more than one psychiatric disorder.
