Egypt's Mursi back at palace after night of protests

CAIRO (Reuters) - Egyptian President Mohamed Mursi returned to work in Cairo on Wednesday, although scores of protesters angered by his drive to push through a new constitution were still blocking one gate of the presidential palace.

The Islamist leader left the palace in the northern Cairo district of Heliopolis on Tuesday evening as tens of thousands of demonstrators surged around it, clashing briefly with police.

A presidential source said Mursi was back at work in the palace, even though up to 200 demonstrators had camped out near one entrance overnight. Traffic was flowing normally in the area where up to 10,000 people had protested the night before, and riot police had been withdrawn, a Reuters witness said.

The rest of the Egyptian capital was calm, despite the political furor over Mursi's November 22 decree handing himself wide powers and shielding his decisions from judicial oversight.

The Islamist leader says he acted to prevent courts from derailing a newly drafted constitution that will go to a referendum on December 15, after which Mursi's decree will lapse.

The Health Ministry said 18 people had been wounded in the clashes on Tuesday. While they fired tear gas when protesters broke through barricades to reach the palace walls, riot police appeared to handle the disturbance with restraint.

"Our demands from the president: retract the presidential decree and cancel the referendum on the constitution," read a placard hung by demonstrators on a palace gate.

The crowds had gathered in what organizers had dubbed a "last warning" to Mursi. "The people want the downfall of the regime," they chanted, roaring the signature slogan of last year's uprising that toppled President Hosni Mubarak.

But the "last warning" may turn out to be one of the last gasps for a disparate opposition which has little chance of stopping next week's vote on a constitution drafted over six months and swiftly approved by an Islamist-dominated assembly.

Facing the gravest crisis of his six-month-old tenure, the Islamist president has shown no sign of buckling under pressure, confident that the Muslim Brotherhood and its Islamist allies can win the referendum and a parliamentary poll to follow.

Woman arrested over 160 dogs living in own waste

TOKYO: A woman who kept 160 starving dogs in her house among tonnes of their own waste has been arrested by Japanese police, an official said Wednesday.

Ten tonnes of animal waste and other rubbish were removed from Noriko Ishii's house after the dogs were taken away, he said.

One Bernese Mountain Dog kept by Ishii, 43, weighed just seven kilograms (15 pounds) -- a sixth of what it should have, said the official in Osaka, adding all the animals were "very scrawny".

Jobless Ishii could face a fine of up to 500,000 yen (US$6,000) if convicted under Japan's animal protection laws.

Government deliberately disrupting Rajya Sabha: Arun Jaitley

NEW DELHI: The government and the parties that support it were intentionally disrupting the Rajya Sabha as it lacked the numbers for a vote on the issue of foreign investment in retail, Bharatiya Janata Party (BJP) leader Arun Jaitley said on Wednesday.

"Since the very first day, the government doesn't seem to be serious about conduct of business, specially in Rajya Sabha," the leader of opposition in the Rajya Sabha told reporters after the house was adjourned for the day.

The opposition, he said, doubted if the ruling party and its supporters would allow the debate on foreign direct investment (FDI) to take place Thursday as scheduled.

"I have the suspicion that the government is unsure which way the Rajya Sabha will vote, so it is not letting the house function. We doubt they will allow the debate on FDI tomorrow (Thursday)," he said.

He said a complaint has been made to the chair of the upper house and an explanation sought from Leader of the House, Prime Minister Manmohan Singh.

"The government is deliberately trying to create an atmosphere that the house cannot function. Even when Lok Sabha is functioning normally, Rajya Sabha is being stalled. The whole nation is watching, not a single opposition member has trooped in the well of the house, it is government members and supporting parties that are stalling the house," he said.

The Rajya Sabha was adjourned Wednesday first due to the Bahujan Samaj Party (BSP), which took up the issue of a memorial for B.R. Ambedkar in Mumbai. At noon, after BSP members were pacified, it was the turn of Samajwadi Party (SP) members to gather near the chairman's podium, shouting slogans against reservations in promotions.

Both parties prop the UPA government from outside.

The debate on FDI in retail is scheduled to start in the upper house on Thursday.

Study: Drug coverage to vary under health law

WASHINGTON (AP) — A new study says basic prescription drug coverage could vary dramatically from state to state under President Barack Obama's health care overhaul.

That's because states get to set benefits for private health plans that will be offered starting in 2014 through new insurance exchanges.

The study out Tuesday from the market analysis firm Avalere Health found that some states will require coverage of virtually all FDA-approved drugs, while others will only require coverage of about half of medications.

Consumers will still have access to essential medications, but some may not have as much choice.

Connecticut, Virginia and Arizona will be among the states with the most generous coverage, while California, Minnesota and North Carolina will be among states with the most limited.

Subway Push Murder Suspect Implicated Self: Police

A suspect believed to be responsible for throwing a man into the path of an oncoming New York City subway train who was taken into custody today has made statements implicating himself, police said.

According to Deputy Commissioner for Public Information Paul Browne, the suspect has been questioned by police since at least early afternoon and while the suspect is in police custody, he has not been officially charged.

Police are continuing to question the suspect and more lineups have been scheduled for tomorrow, Browne said.

Police have not released the suspect's name but began questioning him Tuesday afternoon about the death of Ki-Suck Han, 58, of Queens, N.Y.

Han was tossed onto the subway track at 49th Street and Seventh Avenue around 12:30 p.m. Monday after Han confronted a mumbling man who was alarming other passengers on the train platform. Han tried to scramble back onto the platform, but was crushed by an oncoming train.

The suspect fled the station, prompting a police dragnet for a man described by witnesses and see on surveillance video as a 6-foot-tall, 200-pound black man wearing dreadlocks in his hair.

Witnesses tried to revive the victim after he was hit and provided descriptions of the suspect to police.

Dr. Laura Kaplan, medical resident at Beth Israel Medical Center who was standing on the platform during the incident rushed to give Han aid after he was hit, she said in a statement released by her medical practice today.

"A security guard and I performed 3-4 minutes of chest compressions. I hope the family may find some comfort in knowing about the kindness of these good Samaritans, as they endure this terrible loss," Kaplan said.

"I would like the family to know that many people in the station tried to help Mr. Han by alerting the subway personnel," she said.

Kaplan said she wanted to console the family of Han, who she called "a brave man trying to protect other passengers that he did not know."

The suspect had reportedly been mumbling to himself and disturbing other passengers, according to ABC News affiliate WABC. Police told WABC that the suspect could be mentally disturbed.

The suspect could be heard arguing with Han just moments before he hurled Han onto the track bed, according to surveillance video released by the police. The suspect is heard telling the victim to stand in line and "wait for the R train."

A freelance photographer for the New York Post was on the platform and said he ran towards the train flashing his camera hoping to alert the train to stop in time, but the train caught Han against the shoulder deep platform wall.

The photographer, R. Umar Abbasi, caught an eerie photo of Han with his head and arms above the platform and staring at the oncoming train.

Han was treated by EMS workers on the platform for traumatic arrest and rushed to Roosevelt Hospital, where he was pronounced dead, according to the Fire Department of New York.

"I just heard people yelling. The train came to an abrupt stop about three-quarters into the station and that's when I heard a man was hit by a train," Patrick Gomez told ABC News affiliate WABC.

Police set up a command post outside the train station Monday night searching nearby surveillance cameras to try and get a clear image of the suspect, reports WABC. They said Tuesday that the investigation is ongoing.

Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS (8477). The public can also submit tips by logging onto the Crime Stoppers website at www.nypdcrimestoppers.com or by texting their tips to 274637 (CRIMES) then enter TIP577. All calls are strictly confidential.

Israel says will stick with settlement plan despite condemnation

JERUSALEM (Reuters) - Israel rejected concerted criticism from the United States and Europe on Monday over Prime Minister Benjamin Netanyahu's decision to expand settlement building after the United Nations' de facto recognition of Palestinian statehood.

Washington urged Israel to reconsider its plan to erect 3,000 more homes in the occupied West Bank and East Jerusalem, saying the move hindered peace efforts with the Palestinians.

Britain, France, Spain, Sweden and Denmark summoned the Israeli ambassadors in their capitals to give similar messages.

An official in Netanyahu's office said Israel would not bend. "Israel will continue to stand by its vital interests, even in the face of international pressure, and there will be no change in the decision that was made," the official said.

Angered by the U.N. General Assembly's upgrading on Thursday of the Palestinians' status in the world body from "observer entity" to "non-member state", Israel said the next day it would build the new dwellings for settlers.

Such projects, on land Israel captured in a 1967 war, are considered illegal by most world powers and have routinely drawn condemnation from them. Approximately 500,000 Israelis and 2.5 million Palestinians live in the two areas.

In a shift that raised the alarm among Palestinians and in world capitals, Netanyahu's pro-settler government also ordered "preliminary zoning and planning work" for thousands of housing units in areas including the "E1" zone east of Jerusalem.

Such construction in the barren hills of E1 has never been put into motion in the face of opposition from Israel's main ally, the United States. Building in the area could bisect the West Bank, cut off Palestinians from Jerusalem and further dim their hopes for a contiguous state.

Israeli television stations reported Jerusalem's district planning commission would soon approve plans for several thousand more housing units, including more than 1,000 Israel had shelved two years ago after angering Washington by publishing the plans before a visit by Vice President Joe Biden.

The settlement plan, U.N. Secretary-General Ban Ki-moon said, would deal "an almost fatal blow" to a two-state solution to the Israeli-Palestinian conflict.

French President Francois Hollande said he was "extremely concerned" and Washington made clear it would not back such Israeli retaliation over the U.N. vote, sought by Palestinians after peace talks collapsed in 2010 over settlement building.

"We urge Israeli leaders to reconsider these unilateral decisions and exercise restraint as these actions are counterproductive and make it harder to resume direct negotiations to achieve a two state solution," White House spokesman Jay Carney told a briefing.

Ahead of a Netanyahu visit this week, Germany, considered Israel's closest ally in Europe, urged it to refrain from expanding settlements, and Russia said it viewed the Israeli moves with serious concern.

RETALIATION

Israeli Finance Minister Yuval Steinitz said Israel could not have remained indifferent to the Palestinians' unilateral move at the United Nations.

"I want to tell you that those same Europeans and Americans who are now telling us 'naughty, naughty' over our response, understand full-well that we have to respond, and they themselves warned the Palestinian Authority," he said.

Palestinian chief negotiator Saeb Erekat said building in E1 "destroys the two-state solution, (establishing) East Jerusalem as the capital of Palestine and practically ends the peace process and any opportunity to talk about negotiations in the future".

The United States, one of the eight countries to vote alongside Israel against the Palestinian resolution at the General Assembly, has said both were counterproductive to the resumption of direct peace talks.

In Europe, only the Czech Republic voted against the status upgrade while many countries, including France, backed it. Netanyahu plans to visit Prague this week to express his thanks.

In the Gaza Strip, Sami Abu Zuhri, spokesman for the governing Hamas Islamist movement, called the settlements "an insult to the international community, which should bear responsibility for Israeli violations and attacks on Palestinians".

Israeli police arrested three Jewish settlers on Monday whom they suspect of arson and other crimes against Palestinian property in the West Bank, including the torching of a car.

Attackers have often proclaimed they are exacting a "price tag" for steps taken against the settler movement by Palestinians, or by the Israeli government.

Alongside the settlement plans, Israel announced it would withhold about $100 million in Palestinian tax revenues from the Palestinian Authority, which exercises limited self-rule in the West Bank, saying Palestinians owed $200 million to Israeli firms.

"These are not steps towards peace, these are steps towards the extension of the conflict," Spanish Foreign Minister Jose Manuel Garcia-Margallo said.

Only three weeks ago, Netanyahu won strong European and U.S. support for a Gaza offensive that Israel said was aimed at curbing persistent cross-border rocket fire.

Favored by opinion polls to win a January 22 national election, he brushed off the condemnation and complaints at home that he is deepening Israel's diplomatic isolation.

Netanyahu told his cabinet on Sunday that his government "will carry on building in Jerusalem and in all the places on the map of Israel's strategic interests".

But while his housing minister has said the government would soon invite bids from contractors to build 1,000 homes for Israelis in East Jerusalem and more than 1,000 in West Bank settlement blocs, the E1 plan is still in its planning stages.

"No one will build until it is clear what will be done there," the minister, Ariel Attias, said on Sunday.

Israel froze much of its activities in E1 under pressure from former U.S. President George W. Bush, and the area has been under the scrutiny of his successor, Barack Obama.

Israel cites historical and Biblical links to the West Bank and Jerusalem and regards all of the holy city as its capital, a claim that is not recognized internationally.

Islamic finance to surpass trillion-dollar mark in 2012: Tharman

JOHOR BAHRU: Islamic finance is poised to expand over the next 10 to 15 years after surpassing the trillion-dollar mark in 2012, said Minister for Finance Tharman Shanmugaratnam at the World Islamic Economic Forum in Johor Bahru, Malaysia.

Mr Tharman, who is also Singapore's Deputy Prime Minister, said that he was optimistic about the potential for the sector after it chalked-up growth of about 19 per cent a year since 2006.

This has lifted total Shariah-compliant assets to nearly US$1.3 trillion in 2012.

However there is considerable scope for development since Islamic finance now forms less than 1 per cent of the global financial industry, said Mr Tharman.

Even in Muslim countries, Islamic finance constitutes less than 5 per cent of their financial sector, he added.

The minister also noted that Islamic financial institutions have mainly escaped significant damage from the global financial crisis.

"They are well-placed to grow at a time when many of the global banks, especially the European banks, are deleveraging or focusing on consolidating their balance sheets," said Mr Tharman.

He adds that Islamic finance has the potential to diversify into new growth areas such as trade and infrastructure financing in Asia and emerging markets.

This will allow Islamic banks to reduce their exposure to the real estate sector and take advantage of the stronger growth potential of the emerging market economies.

Another factor that can boost the growth potential of Islamic finance is its focus on transparency, price certainty and the risk-sharing framework.

Mr Tharman says Islamic finance can ride this wave of demand for simpler and more basic investments.

Yet, he also pointed out several challenges in the industry that need to be overcome to ensure continued growth.

Among them is the need to reduce fragmentation in Islamic finance markets due to differences in accepted standards of Shariah compliance.

"This has hampered the flow of liquidity between jurisdictions and is in part why there are presently no Islamic equivalents to the international monetary and bond markets."

The minister also touched on the need to manage capital flows in Asia and emerging market economies.

Excessive capital inflows can cause volatility, and it would be "wise to strengthen our policy toolkits in Asia, so that we can deal with unpredictable and often excessive capital flows," said Mr Tharman.

One of the policy responses should be included in a policy maker's toolkit is to curtail volatility in the exchange rate in the short term, he said.

Mr Tharman also pointed to macro-prudential policies such as property cooling measures to discourage speculative demand for residential properties.

"These targeted administrative and prudential measures are not conventional macroeconomic tools. But they are likely to remain part of our policy toolkit, at least for the foreseeable future."

The Finance Minister has also called for greater depth in Asia's capital markets, especially the corporate bond market.

"Broader and deeper capital markets will allow investors to invest for the long term while hedging risks," Mr Tharman said.

Terrorist attacks soar, India among most affected nations: Study

NEW YORK: The number of terrorist attacks each year has more than quadrupled in the decade since September 11, 2001, a study released on Tuesday said, with Iraq, Pakistan and Afghanistan the most affected.

The number of annual deaths in attacks, however, peaked in 2007 -- the height of the Iraq conflict -- and has been falling ever since. The survey reported 7,473 fatalities in 2011, 25 percent down on 2007. That figure included dead suicide bombers and other attackers.

Iraq, Pakistan, Afghanistan, India and Yemen were the five countries most affected by terrorism in descending order, it said, based on a measure giving weightings to number of attacks, fatalities and injuries and level of property damage.

The Global Terrorism Index - published on Tuesday by the US- and Australia-based Institute for Economics and Peace think tank - ranked countries based on data from the Global Terrorism Database run by a consortium based at the University of Maryland, a commonly used reference by security researchers.

The US military interventions pursued as part of the West's anti-al-Qaida "war on terror", the researchers suggested, may have simply made matters worse - while whether they made the US homeland safer was impossible to prove.

Iraqis account for third of terrorism deaths

"After 9/11, terrorist activity fell back to pre-2000 levels until after the Iraq invasion, and has since escalated dramatically," Steve Killelea, founder and executive chairman of the Institute for Economics and Peace, told Reuters in an e-mail interview.

"Iraq accounts for about a third of all terrorist deaths over the last decade, and Iraq, Pakistan and Afghanistan account for over 50 percent of fatalities."

The study says terrorism incidents numbered 982 in 2002, causing 3,823 deaths, rising to 4,564 terrorist incidents globally in 2011, resulting in 7,473 deaths.

The researchers used the University of Maryland definition of "terrorism": "the threatened or actual use of illegal force and violence by a non-state actor to attain a political, economic, religious, or social goal through fear, coercion, or intimidation".

It did not include casualties from government-backed action such as aerial bombing or other killings.

The study said its methodology allowed researchers the scope to exclude actions that could be seen as insurgency, hate crime or organised crime and incidents about which insufficient information was available.

The upswing in attacks in both Afghanistan and Pakistan only occurred after the Iraq war, the study showed, coming at largely the same time as heightened US-backed military campaigns there by NATO and the Pakistani government respectively.

Syria, Yemen worsening

The findings suggested foreign powers should think twice before intervening militarily, Killelea said, even in countries such as Syria, already seeing widespread bloodshed. Unless the conflict was brought to a swift end, terror attacks might actually increase, he said.

The greatest deterioration in 2011 took place in Syria and Yemen, the report said. Yemen has seen a dramatic upsurge in al Qaeda-linked activity in recent years, while Syrian rebels fighting President Bashar al-Assad have increasingly turned to suicide attacks and bombings.

Of the 158 countries surveyed, only 31 had not experienced a single event classified as a "terrorist act" since 2001, the report said. Even when the 9/11 attacks on New York and Washington were taken into account, North America remained the least-affected region over the period studied.

Western Europeans were 19 times more likely to die in a terrorist attack than North Americans, the report said. Aside from the United States - whose rating improved sharply over the decade as the casualties of 2001 were no longer factored in - the greatest improvements were seen in Algeria and Colombia.

Fossil fuel subsidies in focus at climate talks

DOHA, Qatar (AP) — Hassan al-Kubaisi considers it a gift from above that drivers in oil- and gas-rich Qatar only have to pay $1 per gallon at the pump.

"Thank God that our country is an oil producer and the price of gasoline is one of the lowest," al-Kubaisi said, filling up his Toyota Land Cruiser at a gas station in Doha. "God has given us a blessing."

To those looking for a global response to climate change, it's more like a curse.

Qatar — the host of U.N. climate talks that entered their final week Monday — is among dozens of countries that keep gas prices artificially low through subsidies that exceeded $500 billion globally last year. Renewable energy worldwide received six times less support — an imbalance that is just starting to earn attention in the divisive negotiations on curbing the carbon emissions blamed for heating the planet.

"We need to stop funding the problem, and start funding the solution," said Steve Kretzmann, of Oil Change International, an advocacy group for clean energy.

His group presented research Monday showing that in addition to the fuel subsidies in developing countries, rich nations in 2011 gave more than $58 billion in tax breaks and other production subsidies to the fossil fuel industry. The U.S. figure was $13 billion.

The Paris-based Organization for Economic Cooperation and Development has calculated that removing fossil fuel subsidies could reduce carbon emissions by more than 10 percent by 2050.

Yet the argument is just recently gaining traction in climate negotiations, which in two decades have failed to halt the rising temperatures that are melting Arctic ice, raising sea levels and shifting weather patterns with impacts on droughts and floods.

In Doha, the talks have been slowed by wrangling over financial aid to help poor countries cope with global warming and how to divide carbon emissions rights until 2020 when a new planned climate treaty is supposed to enter force. Calls are now intensifying to include fossil fuel subsidies as a key part of the discussion.

"I think it is manifestly clear ... that this is a massive missing piece of the climate change jigsaw puzzle," said Tim Groser, New Zealand's minister for climate change.

He is spearheading an initiative backed by Scandinavian countries and some developing countries to put fuel subsidies on the agenda in various forums, citing the U.N. talks as a "natural home" for the debate.

The G-20 called for their elimination in 2009, and the issue also came up at the U.N. earth summit in Rio de Janeiro earlier this year. Frustrated that not much has happened since, European Union climate commissioner Connie Hedegaard said Monday she planned to raise the issue with environment ministers on the sidelines of the talks in Doha.

Many developing countries are positive toward phasing out fossil fuel subsidies, not just to protect the climate but to balance budgets. Subsidies introduced as a form of welfare benefit decades ago have become an increasing burden to many countries as oil prices soar.

"We are reviewing the subsidy periodically in the context of the total economy for Qatar," the tiny Persian gulf country's energy minister, Mohammed bin Saleh al-Sada, told reporters Monday.

Qatar's National Development Strategy 2011-2016 states it more bluntly, saying fuel subsides are "at odds with the aspirations" and sustainability objectives of the wealthy emirate.

The problem is that getting rid of them comes with a heavy political price.

When Jordan raised fuel prices last month, angry crowds poured into the streets, torching police cars, government offices and private banks in the most sustained protests to hit the country since the start of the Arab unrest. One person was killed and 75 others were injured in the violence.

Nigeria, Indonesia, India and Sudan have also seen violent protests this year as governments tried to bring fuel prices closer to market rates.

Iran has used a phased approach to lift fuel subsidies over the past several years, but its pump prices remain among the cheapest in the world.

"People perceive it as something that the government is taking away from them," said Kretzmann. "The trick is we need to do it in a way that doesn't harm the poor."

The International Energy Agency found in 2010 that fuel subsidies are not an effective measure against poverty because only 8 percent of such subsidies reached the bottom 20 percent of income earners.

The IEA, which only looked at consumption subsidies, this year said they "remain most prevalent in the Middle East and North Africa, where momentum toward their reform appears to have been lost."

In the U.S., environmental groups say fossil fuel subsidies include tax breaks, the foreign tax credit and the credit for production of nonconventional fuels.

Industry groups, like the Independent Petroleum Association of America, are against removing such support, saying that would harm smaller companies, rather than the big oil giants.

In Doha, Mohammed Adow, a climate activist with Christian Aid, called all fuel subsidies "reckless and dangerous," but described removing subsidies on the production side as "low-hanging fruit" for governments if they are serious about dealing with climate change.

"It's going to oil and coal companies that don't need it in the first place," he said.

Kate's Illness Sometimes Linked to Twins

Hyperemesis gravidarum, the reason newly pregnant Kate Middleton is in the hospital, is a rare but acute morning sickness that results in weight loss and accounts for about 2 percent of all morning sickness, doctors say.

The condition is sometimes associated with women having twins, experts said.

Women diagnosed with hyperemesis gravidarum have lost 5 percent of their pre-pregnancy weight, or 10 pounds, said Dr. Ashley Roman, a professor and OB/GYN at New York University Langone Medical Center.

It poses little danger to the tiny heir, doctors said.

"It's traditionally thought that nausea and vomiting is a sign of a healthy pregnancy," Roman said

Dr. Nancy Cossler, an OB/GYN at University Hospitals in Ohio said the condition does not cause loss of pregnancy or birth defects, but it can be a torture to endure.

"The biggest problem with this is how it interferes with your life," Cossler said. "Constantly feeling sick and puking is difficult."

Hyperemesis gravidarum is thought to be caused by higher levels of the pregnancy hormone, hCG, or human chorionic gonadotropin, Cossler said. Extra hCG can often be brought on by carrying more than one fetus, she said.

In other words, it could be a sign that Middleton is carrying twins. Although there's very little data on twins and hyperemesis gravidarum, one study showed that women carrying twins had a 7.5 percent higher risk of experiencing the acute morning sickness, Roman said.

The extreme morning sickness is usually diagnosed about nine weeks into the pregnancy, and in most cases resolves itself by 16 or 20 weeks, Roman said. In rare cases, it can last the whole pregnancy.

"As the pregnancy is in its very early stages, Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter," a statement from St. James Palace said. Prince William is at the hospital with Middleton, according to the Britain's Press Association.

Roman said doctors prescribe vitamins and ginger capsules at first. If that doesn't stop the vomiting, they will prescribe antihistamines and stronger anti-nausea medications.

Women with hyperemesis gravidarum are also treated with fluids, said Dr. Jessica Young, an OB/GYN at Vanderbilt University. But if left untreated, a pregnant woman who is severely dehydrated for a long period of time could die, "just like any person," Young said.

In extreme cases in which the woman is losing weight and unable to eat, doctors will treat her with intravenous nutrition, Young said.

Hospital stays can vary, and women will often have to be admitted more than once before the condition passes, doctors said.

Hyperemesis gravidarum is somewhat mysterious because some expectant mothers have acute morning sickness during only one of their pregnancies, but have no morning sickness for subsequent pregnancies.

There is a chance that higher levels of hCG, which likely caused Middleton's nausea, could be a sign of a molar pregnancy instead of twins, Cossler said. This would mean Middleton is carrying only a benign growth in her uterus instead of a fetus, or she is carrying a fetus with abnormal DNA and a benign growth. Neither is considered a viable pregnancy.

However, Cossler said molar pregnancies become apparent early on, and doctors would already know whether Middleton had one.

"They would not have released this information," Cossler said of the birth announcement. "I'm certain that they have already eliminated both of those [types of molar pregnancies]."
