CDC: 1 in 24 admit nodding off while driving


NEW YORK (AP) — This could give you nightmares: 1 in 24 U.S. adults say they recently fell asleep while driving.


And health officials behind the study think the number is probably higher. That's because some people don't realize it when they nod off for a second or two behind the wheel.


"If I'm on the road, I'd be a little worried about the other drivers," said the study's lead author, Anne Wheaton of the Centers for Disease Control and Prevention.


In the CDC study released Thursday, about 4 percent of U.S. adults said they nodded off or fell asleep at least once while driving in the previous month. Some earlier studies reached a similar conclusion, but the CDC telephone survey of 147,000 adults was far larger. It was conducted in 19 states and the District of Columbia in 2009 and 2010.


CDC researchers found drowsy driving was more common in men, people ages 25 to 34, those who averaged less than six hours of sleep each night, and — for some unexplained reason — Texans.


Wheaton said it's possible the Texas survey sample included larger numbers of sleep-deprived young adults or apnea-suffering overweight people.


Most of the CDC findings are not surprising to those who study this problem.


"A lot of people are getting insufficient sleep," said Dr. Gregory Belenky, director of Washington State University's Sleep and Performance Research Center in Spokane.


The government estimates that about 3 percent of fatal traffic crashes involve drowsy drivers, but other estimates have put that number as high as 33 percent.


Warning signs of drowsy driving: Feeling very tired, not remembering the last mile or two, or drifting onto rumble strips on the side of the road. That signals a driver should get off the road and rest, Wheaton said.


Even a brief moment nodding off can be extremely dangerous, she noted. At 60 mph, a single second translates to speeding along for 88 feet — the length of two school buses.


To prevent drowsy driving, health officials recommend getting 7 to 9 hours of sleep each night, treating any sleep disorders and not drinking alcohol before getting behind the wheel.

James Holmes Defense: Was He Insane?

James Holmes court appearance mr 120723 wblog James Holmes Defense Witnesses in Colorado Shooting to Testify on Mental State

James Holmes appears in court, Centennial, Colo., July 23, 2012. RJ Sangosti/AP Images.



ABC’s Clayton Sandell and Carol McKinley report:


A judge ruled Thursday that public defenders for accused Colorado theater shooting suspect James Holmes can call two unidentified witnesses at next week’s preliminary hearing to testify about the defendant’s “mental state.”


Arapahoe County, Colo. prosecutors had sought to keep the witnesses out of court, but Judge William Sylvester ruled that the now-25-year-old accused killer has a right to call the witnesses at a preliminary hearing.


The Jan. 7 preliminary hearing will essentially be a mini-trial in which prosecutors will present witness testimony and evidence to convince the judge that there is enough of a case against Holmes to proceed to a trial.


Witnesses to be called for the prosecution include the Aurora police lead detective, first responders, the Arapahoe County coroner and likely a computer forensic specialist, according to prosecution sources who declined to be identified, citing a gag order in the case.


A top priority, the prosecution sources say, will be showing that Holmes acted with premeditation when he allegedly murdered 12 people and wounded 58 on the night of July 20 during a midnight showing of “The Dark Knight Rises.”


Defense attorneys may pursue a legal strategy to show that Holmes was not in his right mind at the time of the shooting.


Holmes, who has not yet entered a plea, has been repeatedly described in court by his legal team as mentally ill. While a graduate student at the University of Colorado, he was in the care of a psychiatrist.


Prosecutors say they will also present photos, video and 911 calls during the hearing, which is expected to last all week.


It’s not clear what the two witnesses’ relationship is to the shooting, or to Holmes.


Prosecutors, Judge Sylvester’s order says, contend that “neither witness has personal knowledge of the events at the Century Aurora 16 Theater.”


Sylvester said the witnesses are non-expert “lay witnesses” who have so far chosen not to be interviewed by defense investigators but have been cooperating with law enforcement.

Central African Republic rebels halt advance, agree to peace talks


DAMARA, Central African Republic (Reuters) - Rebels in Central African Republic said they had halted their advance on the capital on Wednesday and agreed to start peace talks, averting a clash with regionally backed troops.


The Seleka rebels had pushed to within striking distance of Bangui after a three-week onslaught and threatened to oust President Francois Bozize, accusing him of reneging on a previous peace deal and cracking down on dissidents.


Their announcement on Wednesday gave the leader only a limited reprieve as the fighters told Reuters they might insist on his removal in the negotiations.


"I have asked our forces not to move their positions starting today because we want to enter talks in (Gabon's capital) Libreville for a political solution," said Seleka spokesman Eric Massi, speaking by telephone from Paris.


"I am in discussion with our partners to come up with proposals to end the crisis, but one solution could be a political transition that excludes Bozize," he said.


Bozize on Wednesday sacked his Army Chief of Staff and took over the defense minister's role from his son, Jean Francis Bozize, according to a decree read on national radio, a day after publicly criticizing the military for failing to repel the rebels.


The advance by Seleka, an alliance of mostly northeastern rebel groups, was the latest in a series of revolts in a country at the heart of one of Africa's most turbulent regions - and the most serious since the Chad-backed insurgency that swept Bozize to power in 2003.


Diplomatic sources have said talks organized by central African regional bloc ECCAS could start on January 10. The United States, the European Union and France have called on both sides to negotiate and spare civilians.


Central African Republic is one of the least developed countries in the world despite its deposits of gold, diamonds and other minerals. French nuclear energy group Areva mines the country's Bakouma uranium deposit - France's biggest commercial interest in its former colony.


RELIEF IN BANGUI


News of the rebel halt eased tension in Bangui, where residents had been stockpiling food and water and staying indoors after dark.


"They say they are no longer going to attack Bangui, and that's great news for us," said Jaqueline Loza in the crumbling riverside city.


ECCAS members Chad, Congo Republic, Gabon and Cameroon have sent hundreds of soldiers to reinforce CAR's army after a string of rebel victories since early December.


Gabonese General Jean Felix Akaga, commander of the regional force, said his troops were defending the town of Damara, 75 km (45 miles) north of Bangui and close to the rebel front.


"Damara is a red line not to be crossed ... Damara is in our control and Bangui is secure," he told Reuters. "If the rebellion decides to approach Damara, they know they will encounter a force that will react."


Soldiers armed with Kalashnikovs, rocket propelled grenade launchers and truck-mounted machineguns had taken up positions across the town, which was otherwise nearly-abandoned.


Some of the fighters wore turbans that covered their faces and had charms strung around their necks and arms meant to protect them against enemy bullets.


Chad's President Idriss Deby, one of Bozize's closest allies, had warned the rebels the regional force would confront them if they approached the town.


Chad provided training and equipment to the rebellion that brought Bozize to power by ousting then-president Ange Felix Patasse, who Chad accused of supporting Chadian dissidents.


Chad is also keen to keep a lid on instability in the territory close to its main oil export pipeline and has stepped in to defend Bozize against insurgents in the past.


A CAR government minister told Reuters the foreign troop presence strengthened Bozize's bargaining position ahead of the Libreville peace talks.


"The rebels are now in a position of weakness," the minister said, asking not to be named. "They should therefore stop imposing conditions like the departure of the president."


Central African Republic is one of a number of countries in the region where U.S. Special Forces are helping local soldiers track down the Lord's Resistance Army, a rebel group which has killed thousands of civilians across four nations.


France has a 600-strong force in CAR to defend about 1,200 of its citizens who live there.


Paris used air strikes to defend Bozize against a rebellion in 2006. But French President Francois Hollande turned down a request for more help, saying the days of intervening in other countries' affairs were over.

Football: Redknapp eyes salvation after shock win at Chelsea






LONDON: Harry Redknapp believes Queens Park Rangers' shock 1-0 win at Chelsea could be the turning point in his side's season.

Redknapp, who also revealed he missed out on the chance to sign Liverpool's Joe Cole, saw his side defy the odds to produce one of the most unexpected results of the season thanks to Shaun Wright-Phillips's goal on Wednesday.

The win was only their second league victory of the season and moved Rangers level on points with second-bottom Reading, five points adrift of safety.

But the manager believes the impact of the result will be hugely significant in the context of the relegation battle and strengthen his chances of bringing in new recruits in the January transfer window.

"I had a good meeting with (the players) after the Liverpool game (QPR lost 3-0) and I think I convinced them I thought we could stay up," he said.

"You probably thought I was mad, but I didn't go home thinking we are doomed. I thought we could turn it around if we can get this lot working and get someone in the window. And tonight (Wednesday) has proved that.

"Most important, we worked hard. We grafted and if we do that until the end of the season, we will win some games. The other teams down there will be thinking: 'That's not very good.' I've been there.

"That will send shocks through everybody and we've got to make the most of that tonight."

Redknapp had attempted to sign Cole but missed out when the player opted to join his former club West Ham United instead.

"I lost a player today who I tried to sign and who would have been my first signing," said Redknapp.

"He probably looked and thought: 'Harry, I love you, but I don't think you are going to stay up.' And he's gone to the Hammers.

"I was going to take Joe. I thought he would have been good for me but it's not easy when you are down there.

"I understand why -- he's a West Ham lad and they love him. I signed him there when he was 11, so he's going back home and I wish him all the luck in the world."

Chelsea's interim manager, Rafael Benitez, blamed his side's defeat on fatigue and admitted they cannot afford further slips if they are to close the 14-point gap on leaders Manchester United.

Benitez admitted striker Fernando Torres is one of the players who needs a rest and says he hopes to have completed the signing of Newcastle United forward Demba Ba before the FA Cup tie at Southampton on Saturday.

The manager made changes to his line-up and said: "We can't carry on with the same players. We were playing the bottom of the league at home and you have to trust your players.

"The main thing is we were a bit tired and couldn't produce the pass, the intensity and the movement.

"We have to have everything almost perfect now. When you lose a game it is more difficult, but I can't be thinking about the number of points -- only the next game.

"We have the FA Cup now, then we have to think how we can get three points from every game."

And he added: "Fernando is one of the players (who is tired). You can see two or three, who have been playing too many games in the last month.

"Definitely the club is working on it (signing a new striker). If we can do the business, I hope so (before weekend)."

Benitez revealed goalkeeper Petr Cech will be out for up to three weeks with an adductor problem, but there is still no return date for skipper John Terry, who has a knee injury.

Brain image study: Fructose may spur overeating


This is your brain on sugar — for real. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating.


After drinking a fructose beverage, the brain doesn't register the feeling of being full as it does when simple glucose is consumed, researchers found.


It's a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role. These sugars often are added to processed foods and beverages, and consumption has risen dramatically since the 1970s along with obesity. A third of U.S. children and teens and more than two-thirds of adults are obese or overweight.


All sugars are not equal — even though they contain the same amount of calories — because they are metabolized differently in the body. Table sugar is sucrose, which is half fructose, half glucose. High-fructose corn syrup is 55 percent fructose and 45 percent glucose. Some nutrition experts say this sweetener may pose special risks, but others and the industry reject that claim. And doctors say we eat too much sugar in all forms.


For the study, scientists used magnetic resonance imaging, or MRI, scans to track blood flow in the brain in 20 young, normal-weight people before and after they had drinks containing glucose or fructose in two sessions several weeks apart.


Scans showed that drinking glucose "turns off or suppresses the activity of areas of the brain that are critical for reward and desire for food," said one study leader, Yale University endocrinologist Dr. Robert Sherwin. With fructose, "we don't see those changes," he said. "As a result, the desire to eat continues — it isn't turned off."


What's convincing, said Dr. Jonathan Purnell, an endocrinologist at Oregon Health & Science University, is that the imaging results mirrored how hungry the people said they felt, as well as what earlier studies found in animals.


"It implies that fructose, at least with regards to promoting food intake and weight gain, is a bad actor compared to glucose," said Purnell. He wrote a commentary that appears with the federally funded study in Wednesday's Journal of the American Medical Association.


Researchers now are testing obese people to see if they react the same way to fructose and glucose as the normal-weight people in this study did.


What to do? Cook more at home and limit processed foods containing fructose and high-fructose corn syrup, Purnell suggested. "Try to avoid the sugar-sweetened beverages. It doesn't mean you can't ever have them," but control their size and how often they are consumed, he said.


A second study in the journal suggests that only severe obesity carries a high death risk — and that a few extra pounds might even provide a survival advantage. However, independent experts say the methods are too flawed to make those claims.


The study comes from a federal researcher who drew controversy in 2005 with a report that found thin and normal-weight people had a slightly higher risk of death than those who were overweight. Many experts criticized that work, saying the researcher — Katherine Flegal of the Centers for Disease Control and Prevention — painted a misleading picture by including smokers and people with health problems ranging from cancer to heart disease. Those people tend to weigh less and therefore make pudgy people look healthy by comparison.


Flegal's new analysis bolsters her original one, by assessing nearly 100 other studies covering almost 2.9 million people around the world. She again concludes that very obese people had the highest risk of death but that overweight people had a 6 percent lower mortality rate than thinner people. She also concludes that mildly obese people had a death risk similar to that of normal-weight people.


Critics again have focused on her methods. This time, she included people too thin to fit what some consider to be normal weight, which could have taken in people emaciated by cancer or other diseases, as well as smokers with elevated risks of heart disease and cancer.


"Some portion of those thin people are actually sick, and sick people tend to die sooner," said Donald Berry, a biostatistician at the University of Texas MD Anderson Cancer Center in Houston.


The problems created by the study's inclusion of smokers and people with pre-existing illness "cannot be ignored," said Susan Gapstur, vice president of epidemiology for the American Cancer Society.


A third critic, Dr. Walter Willett of the Harvard School of Public Health, was blunter: "This is an even greater pile of rubbish" than the 2005 study, he said. Willett and others have done research since the 2005 study that found higher death risks from being overweight or obese.


Flegal defended her work. She noted that she used standard categories for weight classes. She said statistical adjustments were made for smokers, who were included to give a more real-world sample. She also said study participants were not in hospitals or hospices, making it unlikely that large numbers of sick people skewed the results.


"We still have to learn about obesity, including how best to measure it," Flegal's boss, CDC Director Dr. Thomas Frieden, said in a written statement. "However, it's clear that being obese is not healthy - it increases the risk of diabetes, heart disease, cancer, and many other health problems. Small, sustainable increases in physical activity and improvements in nutrition can lead to significant health improvements."

Tax Deal Done - but How Can Obama Sign It?


Jan 2, 2013 6:29pm







ap obama ac 130102 wblog Vacationing Obamas Options to Sign Fiscal Cliff Deal Include Air Force Jet, Autopen

AP Photo/Charles Dharapak


Congress officially delivered the bill to avert the fiscal cliff to the White House this afternoon, House Speaker John Boehner’s office told ABC News.


Now the question is when will the President sign it?


The bill, passed late on New Year’s Day, expires tomorrow at 11:59 a.m. when the current session of Congress concludes. If President Obama doesn’t sign it by then, constitutionally the bill is dead.


But this evening, eighteen hours before the deadline, the President is on a golf course in Hawaii.  And the bill is in Washington at the White House.


Administration officials won’t say what they will do despite repeated inquiries from ABC News.


There seem to be two options:  1) An Air Force jet can deliver the bill to Hawaii (better leave quickly!) in time for the President to sign it before 11:59 Eastern Standard Time; or, 2) The White House can use a presidential “auto-pen.”


The simple mechanical device uses a template of the presidential signature to scrawl it on paper if activated by the White House at Obama’s direction.


But would an auto-pen – usually used to sign insignificant correspondence and photographs – pass constitutional muster?  We don’t know.  The question has never been tested by the courts.


A 2005 legal study commissioned by former President George W. Bush determined that use of the autopen is constitutional but acknowledged the possibility that its use could be challenged.  Bush never used the autopen, officials from his administration told ABC.


President Obama is only believed to have used the autopen once to sign a piece of major legislation — the 2011 extension of the Patriot Act — which reached his desk while he was on a diplomatic trip to Europe. Officials invoked national security concerns to justify the move.


Use of the autopen has been controversial.  Conservative groups alleged last summer that Obama used an autopen to sign condolence letters to the families of Navy SEALs killed in a Chinook crash in Afghanistan — a charge the White House disputed flatly as false.


In 2004, then-Secretary of Defense Donald Rumsfeld was criticized for using an autopen to sign condolence letters to the families of fallen troops.


And in 1992 then-Vice President Dan Quayle even got into some hot water over his use of the autopen on official correspondence during an appearance on “This Week with David Brinkley.” More HERE.

At least 61 crushed to death in Ivory Coast stampede


ABIDJAN (Reuters) - At least 61 people were crushed to death in a stampede after a New Year's Eve fireworks display at a stadium in Ivory Coast's main city Abidjan early on Tuesday, officials said.


Witnesses said police had tried to control crowds around the Felix Houphouet-Boigny Stadium following the celebrations, triggering a panic in which scores were trampled.


"The estimate we can give right now is 49 people hospitalized ... and 61 people dead," said the chief of staff of Abidjan's fire department Issa Sacko.


Crying women searched for missing family members outside the stadium on Tuesday morning. The area was covered in patches of dried blood and abandoned shoes.


"My two children came here yesterday. I told them not to come but they didn't listen. They came when I was sleeping. What will I do?" said Assetou Toure, a cleaner.


Sanata Zoure, a market vendor injured in the incident, said New Year's revelers going home after watching the fireworks had been stopped by police near the stadium.


"We were walking with our children and we came upon barricades, and people started falling into each other. We were trampled with our children," she said.


Another witness said police arrived to control the crowd after a mob began chasing a pickpocket.


President Alassane Ouattara called the deaths a national tragedy and said an investigation was under way to find out what happened.


"I hope that we can determine what caused this drama so that we can ensure it never happens again," he said after visiting the injured in hospital.


The country, once a stable economic hub for West Africa, is struggling to recover from a 2011 civil war in which more than 3,000 people were killed.


Ivory Coast's security forces once were among the best trained in the region, but a decade of political turmoil and the 2011 war has left them in disarray.


At least 18 people were killed in another stampede during a football match in an Abidjan stadium in 2009.

Colorado town in the thick of fracking dispute






Longmont, COLORADO: The US oil and gas industry is condemning a move by one Colorado town to impose its own ban on the practice of hydraulic fracturing.

Voters in Longmont have chosen to outlaw the controversial practice within city limits, but drillers and the state government said the city has overstepped its bounds.

Space for large houses with mountain views -- one of the reasons the population of the Colorado city of Longmont has grown steadily over the past twenty years. But some residents are not happy with a new neighbour that has moved in recent years.

Natural gas wells and pipelines have sprung up around Longmont - often very close to subdivisions.

Michael Bellmont, one of the activists involved in a recent campaign to ban hydraulic fracturing in Longmont, said modern fracking practices use chemicals that can contaminate surrounding air and water, and is dangerous to health.

He said: "if you live within half a mile of these wells, one is 250 per cent more likely to have negative and chronic health impacts, and 60 per cent more likely to get cancer."

The majority of Longmont voters agree with Bellmont -- in November, they approved the ban on hydraulic fracturing in the city by a 60 to 40 per cent margin.

That ban has triggered a row with the oil and gas industry, which already leases land and drills in Longmont, and maintains fracking is safe.

Colorado governor John Hickenlooper -- a supporter of the oil and gas industry -- expects drilling companies to sue to overturn the ban.

Tisha Conoly Schuller, president and CEO of the Colorado Oil & Gas Association, said: "The oil and gas industry -- we're evaluating our options, and then the state government has also been looking at their options. So I imagine we will see a lawsuit in Longmont, and there's lots of different ways it could come about."

Environmentalists are locked in a heated debate with county and state regulators over the issue -- including proposed rules on how far wells should be from people's homes.

Dr William Fleckenstein of the Colorado School of Mines said: "It adds a lot of jobs, there's a lot of rigs that are there. But at the same time, the rigs that are drilling -- the pipelines are going to impact people's lives and the industry has to take into account those impacts."

In Longmont, the city is gearing up for a protracted and expensive legal battle -- one which could set a precedent for other towns and cities that want to take matters regarding fracking into their own hands.

NHAI slams GMR for termination notice for biggest highway project

NEW DELHI: National Highways Authority of India (NHAI) has hit back at infrastructure major GMR on its termination notice for the country's biggest highway project worth at least Rs 6,000 crore. The Authority in its reply to GMR has said that the company did not give 90-day cure period (to rectify and address the deficiencies), and how it is in violation of the norms laid down in the concession agreement.

NHAI was to respond to the GMR notice to exit from Kishangarh-Udaipur-Ahmedabad project by January 4. GMR has cited NHAI's failure to get environmental clearance for the 555-km highway project and to notify the revised toll rate on this stretch being widened from four to six lanes.

"The notice served on us had several deficiencies, and we have spelt them out clearly. The revised toll notification has been done and environment clearance will be obtained in the next few days," said a senior NHAI official.

Sources said that the toll notification was done after highways minister C P Joshi held a meeting at his residence on Monday evening and the environment and forest ministry (MoEF) has been approached to convene a special meeting of the Forest Advisory Committee (FAC) to grant clearance.

The project has huge significance considering it being the country's first mega highway project. In addition, if the contract gets cancelled, NHAI would directly lose revenue of Rs 636 crore annually, which increases 5% every successive year. The Authority's own estimate shows the total revenue during the entire contract period would be at least Rs 9,000 crore at net present value.

Indications abound that in case GMR still decides to opt out of the project, NHAI would forfeit the company's bank guarantee along with other harsh steps. "We don't want this to be a precedent for other concessionaires who would show delay in environment clearance to exit from the project and consequently forcing us to rebid them," said a senior ministry official.

NHAI also seems to use this case to draw MoEF's attention to fast track green clearance, highlighting the laxity on the green ministry's part to grant such nods. NHAI chairman R P Singh wrote to MoEF secretary V Raja Gopalan on December 24, "Any delay on our part in giving environment clearance can be construed as an indirect support to the contention of the concessionaire" while seeking his personal invention to convene a special meeting of the FAC.

According to NHAI, the project got environment clearance in early June, with a rider that stage-1 of forest clearance for the venture is obtained. This requires diversion of 37.62 hectares reserved forest and 40.39 hectares of protected forest that fall in Rajasthan. The state government has processed and sent its proposal in mid-November. Even after some of the queries of MoEF were cleared, the proposal was not placed before the FAC that met on December 21 and 22.

A part of the project also falls in Gujarat, and hence forest diversion is required for 173.39 hectares. NHAI officials said that the Gujarat government has given its nod after the poll code for the assembly election was lifted.
