Forget expensive gifts, it really is the thought that counts




Forget expensive gifts or sexy lingerie – what people want is a love letter, a handwritten poem or a passionate embrace, according to a new study by British Heart Foundation shops in support of their annual Love Notes fundraising campaign as part of National Heart Month.

The survey reveals that 82 per cent of people from the South East prefer thoughtful romantic gestures, and fewer than one in five expect expensive gifts.
The Love Note promotion is available in BHF shops until Valentine’s Day. For a minimum £1 donation you can declare your love in the shop window.
There’s also a chance to win a luxury spa stay for two – just email a picture of you and your partner along with 200 words about your great love story to love@bhf.org.uk.
The BHF’s Angie Vidler said: “Posting a Love Note in a BHF Shop window is one of the easiest ways you can show your love for that special someone whilst the small donation of £1 will help the BHF continue its life-saving work.”

Premature cancer deaths ‘can be prevented’


The World Cancer Research Fund (WCRF) has said that 13,000 premature deaths from cancer “could be prevented” in the UK every year.
Around 157,000 people die every year from the disease in the UK annually. The predicted number of deaths is expected to increase to 182,000 by 2025.
The Union for International Cancer Control, which works in 155 countries around the world, has estimated that 1.5 million deaths from the disease could be prevented if awareness was increased. 
The WCRF carried out a survey of 2,000 people in Britain and found over a quarter (28%) believed there was nothing they could do to reduce their cancer risk.
Dr Kate Allen, executive director of science and public affairs at WCRF, said the results of the study were a concern.
She explained: “They show that a significant proportion of people don’t realise that there’s a lot they can do to reduce their risk of cancer. By eating healthily, being physically active and keeping to a healthy weight, we estimate that about a third of the most common cancers could be prevented.”
“Everyone has a role to play in preventing cancer but governments and health professionals are key to raising awareness and making it easier for individuals to change their lifestyle habits.”

‘Unfriending’ on Facebook and real-life consequences


If you’re on Facebook, chances are good there is at least one “friend” you constantly think about “unfriending.”
A new University of Colorado – Denver study uncovers that there are real-life consequences of ending that online relationship.
“Now it’s like the digital version of flipping someone off I think,” says Facebook use Luciann Lajoie.
Unfriending a Facebook friend can really make people unfriendly.
“So these were people who were unfriended and knew about it and the said, ‘Oh I think that person sent me a signal and I no longer want to see that person.’ So they would be uncomfortable seeing them, and they will avoid seeing them,” says CU-Denver researcher Christopher Sibona.
The study found four main reasons that lead to unfriending on Facebook:
1) Posting unimportant material
2) Posting political or religious rants
3) Posting sexist or racist remarks
4) Posting just plain, boring stuff
“Women were more strongly likely to avoid people after being unfriended,” Sibona says.
“I usually just let them post whatever they want and I just don’t read it,” says Facebook user Alyssa Odorisio. “I think a lot of people do unfriend people or they did a couple of years ago and it was just drama. I try to avoid it.”
It’s drama that causes hurt feelings.
The study points out the power of being ostracized on social media and feelings of reduced self-esteem.
“It’s definitely something that affects people on a pretty deep level,” Luciann Lajoie says.
Researchers are just starting to understand how deep that level goes.

About Energy Drinks


As concerns over the safety of energy drinks continue to grow, a study outlines the recent evidence regarding the content, benefits, and risks of the beverages that are popular with adolescents.
The study, published in the journal Pediatrics, reports that more teens are downing energy drinks; in 2003 16% regularly consumed the drinks while in 2008,  that percentage jumped to 35%. One study of college student consumption found 50% of students drank at least one to four a month. This year, research documented a jump in energy drink-related emergency room visits and politicians and consumers called upon the Food and Drug Administration (FDA) to look into deaths associated with the drinks.
What do the beverages contain that could pose a health hazard? Currently, the amount of caffeine added to energy drinks is not regulated by the FDA, so often the amounts listed (if they’re listed) are inaccurate. Studies also don’t support all of the claims made by the manufacturers on some of the other ingredients’ ability to maintain energy. The study authors broke down the most common ingredients found in energy drinks: caffeine, guarana, taurine, ginseng, sugars and B vitamins and why they might be problematic.
Caffeine
This is the primary ingredient in energy drinks, and its levels can vary widely. Energy drinks do not fall under the same regulatory category as sodas and often have higher levels of the stimulant than indicated. For comparison, a 6.5 oz cup of coffee contains 80 to 120 mg of caffeine, tea has about 50 mg, and a 12 oz cola cannot have more 65 mg. Energy drinks have significantly higher amounts, with the most well-known brands containing anywhere from 154 mg in a 16 oz Red Bull to 505 mg in a 24 oz Wired X505. There is no official recommended limit for the amount of caffeine a person can consume, but excessive caffeine has been linked to a variety of adverse effects such as high blood pressure, premature birth and possibly sudden death.
Guarana
Also known as Brazilian cocoa, guarana is a plant from South America that contains a caffeine compound called guaranine. One gram of guarana is equal to 40 mg of caffeine. But even if it’s in energy drinks, it’s typically not included in the total caffeine tally. “In reality, when a drink is said to contain caffeine plus guarana, it contains caffeine plus more caffeine,” the authors write. The FDA has not assessed guarana, so it’s risks and benefits remain unknown.
Sugars
The sugar content in energy drinks ranges from 21 g to 34 g per 8 oz, and can come in the form of sucrose, glucose, or high fructose corn syrup. “Users who consume two or three energy drinks could be taking in 120mg to 180 mg of sugar, which is 4 to 6 times the maximum recommended daily intake,” the authors write, noting that adolescents who consume energy drinks could be at risk for obesity and dental problems.
Taurine
As one of the most common amino acids in the body, taurine can support brain development and regulate the body’s mineral and water levels, and could even improve athletic performance. It’s found naturally in meat, seafood and milk. The study authors say the amount of taurine consumed from energy drinks is higher than that in a normal diet. As of yet, there is no evidence this is unhealthy, but there is also no evidence that consuming large amounts is beneficial for the human body.
“Some energy drinks [contain] super-physiologic amounts of these ingredients, embracing the mantra ‘more is better.’ I’m not sure this mantra should necessarily apply,” says study author Dr. Kwabena Blankson, an Air Force pediatrician specializing in teen medicine at Portsmouth Naval Medical Center. “Many energy drink ingredients that are ‘healthy’ are vitamins or minerals you probably get even if you don’t eat the most balanced diet. American foods are heavily fortified. For the average consumer, energy drinks don’t even tell you how much of these special ingredients you are getting, couching the quantities behind the term ‘proprietary blend’ or ‘energy blend.’”
Ginseng
There are claims that ginseng boosts athletic performance, strengthens the immune system and improves mood. But the authors say there is little proof of this, and there isn’t enough ginseng in energy drinks to offer any benefit. The root has also been linked to increased risk of insomnia, headache and hypertension. “Ginseng should be used cautiously, as it can cause undesirable side effects in high doses and may even be dangerous when taken with certain medicines or if the patient is undergoing surgery,” according to the American Cancer Society.
B vitamins and other additives
Studies suggest that B vitamins can improve mood and even fight heart disease and cancer, but the amount contained in each energy drink isn’t enough to have any meaningful effect.
There are also a number of other additives that the authors say need further study. “I was surprised by the profound lack of science supporting the benefit of ingesting some these ingredients such as carnitine, Yohimbe, and bitter orange,” says Blankson. “Adolescent consumers have no idea what these ingredients do. They assume that because they can easily buy it off the shelf that it must be safe for them.” The fact is, however, that there isn’t much scientific evidence on the risks or benefits of these additives—and very little is known about the effects of daily energy drink consumption over the long-term.
The study also highlights the fact that many teens mix their energy drinks with alcohol, which can mask the effects of alcohol and give drinkers the impression they’ve consumed less than they have. Given the lack of knowledge about how energy drinks and alcohol interact, as well as how the beverages mix with medications and antidepressants, the researchers also urge physicians to be aware of energy drink consumption, particularly among teens, and suggest educating patients and parents on the potential consequences of making energy drinks a regular habit.

Super Bowl power outage: What went wrong?


Super Bowl XLVII’s dramatic second half was made more so by a power blackout, which halted play and left millions of TV viewers in the dark.
The biggest pro football game of the year was in limbo for more than a half-hour Sunday night because of the outage, which plunged parts of the Superdome into darkness, with no clear explanation as to why.
The Baltimore Ravens were leading the San Francisco 49ers 28-6 when most of the lights in the 73,000-seat building went out with 13:22 left in the third quarter Sunday night.
CBS News correspondent Armen Keteyian was just finishing an interview in the NFL control room with the league’s Senior Vice President (Events), Frank Supovitz — the man in charge of the NFL’s entire Super Bowl Game Day operation — when power went out.
“We were talking about a halftime timing clock when everything changed,” Keteyian told “CBS This Morning.”
“All right, we lost lights,” said Supovitz, as rows of lights in the Superdome shut down.
In the control room there was no panicking, said Keteyian, but there there was a certain amount of confusion.
Jim Nantz, who was calling the game for CBS Sports, lost communication. “We were out, we were completely dark,” Nantz told CBS News correspondent Jeff Glor. “I couldn’t see chart boards or anything. I wasn’t even sure if they’d be able to restart the game.”

 Play did resume, but it took 34 minutes. And when the power came back, so did the 49ers, coming back from a 22-point deficit to a squeaker 34-31 loss to the Ravens.
About two hours after the game, officials revealed that an “abnormality” in the power system triggered an automatic shutdown, forcing backup systems to kick in. But they weren’t sure what caused the initial problem.
 New Orleans Mayor Mitch Landrieu called the power outage “an unfortunate moment in what has been an otherwise shining Super Bowl week for the city of New Orleans.”
“In the coming days, I expect a full after-action report from all parties involved,” he said.
Auxiliary power kept the playing field from going totally dark, but escalators stopped working, credit-card machines shut down, and the concourses were only illuminated by small banks of lights tied in to emergency service.
 Most fans seemed to take the outage in stride, even starting up the wave to pass the time.
 ”So we had to spend 30 minutes in the dark? That was just more time for fans to refill their drinks,” said Amanda Black of Columbus, Miss.
 A joint statement from Entergy New Orleans, which provides power to the stadium, and Superdome operator SMG shed some light on the chain of events, which apparently started at the spot where Entergy feeds power into the stadium’s lines. The problem occurred shortly after Beyonce put on a halftime show that featured extravagant lighting and video effects.
A joint statement from Entergy New Orleans, which provides power to the stadium, and Superdome operator SMG shed some light on the chain of events, which apparently started at the spot where Entergy feeds power into the stadium’s lines. The problem occurred shortly after Beyonce put on a halftime show that featured extravagant lighting and video effects.
“A piece of equipment that is designed to monitor electrical load sensed an abnormality in the system,” the statement said. “Once the issue was detected, the sensing equipment operated as designed and opened a breaker, causing power to be partially cut to the Superdome in order to isolate the issue. … Entergy and SMG will continue to investigate the root cause of the abnormality.”
 The FBI quickly ruled out terrorism, and the New Orleans Fire Department dismissed reports that a fire might have been the cause.
 Auxiliary power kept the playing field and concourses from going totally dark.
 On the CBS broadcast, play-by-play announcers Jim Nantz and Phil Simms went silent. Sideline reporter Steve Tasker announced to viewers a “click of the lights” as the problem. Later, the halftime crew anchored by host James Brown returned to fill the time with football analysis. Brown said a power surge caused the outage.
The failure occurred shortly after Jacoby Jones returned the opening kickoff of the second half for a 108-yard touchdown, the longest play in Super Bowl history and pushing the Ravens to a commanding lead. But when play resumed, the momentum totally changed.
 The Niners scored two straight touchdowns and nearly pulled off a game-winning drive in the closing minutes. They had first down inside the Ravens 10, but Baltimore kept them out of the end zone to preserve the victory.
 The blackout, it turned out, became more of a footnote than a spark to what would have been the greatest comeback in Super Bowl history.
 ”It just took us longer to lose,” moaned San Francisco linebacker Ahmad Brooks.
 No one could remember anything like this happening in the title game, but it wasn’t unprecedented.
Just last season, the Niners endured two power outages during a Monday night game against the Pittsburgh Steelers at Candlestick Park.
 ”I didn’t know what was going on,” San Francisco safety Dashon Goldson said. “I just tried to keep my legs warmed up.”
 The Ravens felt the delay turned what looked like a blowout into a close game.
 ”It really hurt us. We had lot of momentum,” fullback Vonta Leach said. “We were rolling. That 35- or 40-minute wait, whatever it was, hurt our momentum as far as what we were trying to do. But we came out on top and that’s all that matters.”
 Safety Ed Reed said some of his teammates were worried that the game would turn when the lights came back on.
 ”The bad part is we started talking about it,” he said. “Some of the guys were saying, ‘They’re trying to kill our momentum.’ I was like, ‘There’s two teams on the field.’ But once we started talking about it, it happened. We talked it up.”
 The public address announcer said the Superdome was experiencing an interruption of electrical service and encouraged fans to stay in their seats. Players milled around on the sidelines, some took a seat on the bench, others on the field. A few of the Ravens threw footballs around.
 Officials gathered on the field and appeared to be talking to stadium personnel. Finally, the lights came back on throughout the dome and the game resumed.
 ”Let’s go!” referee Jerome Boger said to the teams.
 The NFL said stadium officials were investigating the cause.
 ”We sincerely apologize for the incident,” Superdome spokesman Eric Eagan said.
 Once the game resumed, CBS said all commercial commitments for the broadcast were being honored. The network sold out its allotment of advertising at $3.8 million per 30-second spot.
 ”We lost numerous cameras and some audio powered by sources in the Superdome,” said Jennifer Sabatelle, vice president of communications for CBS Sports. “We utilized CBS’ backup power and at no time did we leave the air.”
 The outage provided a major glitch to what has largely been viewed as a smooth week for New Orleans, which was hosting its first Super Bowl since 2002 and was eager to show off how the city has rebuilt since Hurricane Katrina.
 Monique Richard, who is from the north shore of Lake Pontchartrain, had tickets in the upper deck.
 ”My exact words on the way over here were, ‘I hope this goes off without a hitch,’ because the city just looked so good, they were doing so well, the weather so good everything was kind of falling into place,” she said.
 New Orleans was once a regular in the Super Bowl rotation and hopes to regain that status. Earlier in the week, the host committee announced it will bid on the 2018 Super Bowl, which would coincide with the 300th anniversary of the city’s founding.
 The 38-year-old Superdome has undergone $336 million in renovations since Katrina ripped its roof in 2005. Billions have been spent sprucing up downtown, the airport, French Quarter and other areas of the city in the past seven years.
 ”Everything shut down,” said Carl Trinchero, a 49ers fan from Napa, Calif., who was in the Superdome. “No credit cards, vending machines shut down, everything shut down.”
 Trinchero said it may have affected the momentum of the game but, given that the Ravens survived the 49ers comeback, “It didn’t affect the outcome.”
 Joked Doug Cook, a Ravens fan from New Orleans: “They didn’t pay the light bill.”
 Still, he admitted to a fleeting fear when the lights went out.
 ”I started thinking it was a terrorist attack. I was a little nervous,” he said.
 In the French Quarter, fans didn’t appear much concerned with the power outage or delay in play.
 ”If we can blame Beyonce for lip syncing, we can blame her for the power outage,” said Gary Cimperman of Slidell, La., with a laugh as he watched the second half of the game from a bar. “Or maybe Sean Payton called in the outage, bountygate part two.”

Asteroid 2012 DA14 to Fly By Earth in ‘Record Setting’ Close Shave

Half the size of a football field, asteroid 2012 DA14 will give the Earth a “record-setting” close shave, passing closer to our planet than many satellites when it buzzes by later this month, NASA scientists announced.
The asteroid is set to whiz past Earth Feb. 15, and will come within 17,200 miles of the planet when it makes its cosmic fly by. Asteroid 2012 DA14 will approach the Earth even closer than the moon, well inside the paths of navigation and communications satellites, according to Space.com.
“This is a record-setting close approach,” Don Yeomans, the head of NASA’s asteroid-tracking program, said in a statement.
“Since regular sky surveys began in the 1990s, we’ve never seen an object this big get so close to Earth.”
Discovered last year by an amateur team of astronomers at the La Sagra Sky Survey observatory in Spain, the asteroid measures roughly 164 feet across. Yeomans emphasized that while the approach of 2012 DA14 will bring it closer than the geosynchronous satellites orbiting 22,245 miles above Earth, there’s no real threat of the asteroid colliding with the planet.
“2012 DA14 will definitely not hit Earth. The orbit of the asteroid is known well enough to rule out an impact,” said Yeomans, who heads the Near-Earth Object Program at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. The odds that the asteroid could slam into a satellite are also “extremely remote,” he added.
Asteroid 2012 DA14 is a fairly typical type of asteroid. Earth comes into “close” contact with such asteroids about every 50 years, and is only hit by them every 1,200 years, Yeomans estimated. The impact of an asteroid like 2012 D14 would not be catastrophic over a wide area, Yeomans said.
NASA officials explained asteroid 2012 DA14 is roughly the same size as the object that exploded in the atmosphere above Siberia in 1908, which leveled hundreds of square miles in what scientists refer to as the “Tunguska Event.”
An asteroid about the same size as 2012 DA14 slammed into the Earth 50,000 years ago, creating the famous Meteor Crater in Arizona, Yeomans said. Although, that asteroid responsible for the Meteor Crater was made of iron, making its impact especially powerful.
NASA plans to track the space rock closely as it makes its celestial close encounter with Earth. The agency will use its Goldstone radar in California’s Mojave Desert to follow the asteroid from Feb. 16 to Feb. 20.
Amateurs may have a difficult time spotting the object when it crosses paths with Earth later this month. Scientists say asteroid 2012 DA14 will arrive like a bullet train. The object will be traveling so fast that only the most experienced astronomers are likely to see it as it whizzes by the planet.
“The asteroid will be racing across the sky, moving almost a full degree (or twice the width of a full moon) every minute,” Yeomans said. “That’s going to be hard to track.”

The Gun Challenge


The debate over what to do to reduce gun violence in America hit an absurd low point on Wednesday when a Senate witness tried to portray a proposed new ban on assault rifles and high-capacity magazines as some sort of sexist plot that would disproportionately hurt vulnerable women and their children.
The witness was Gayle Trotter, a fellow at the Independent Women’s Forum, a right-wing public policy group that provides pseudofeminist support for extreme positions that are in fact dangerous to women. She told the Senate Judiciary Committee that the limits on firepower proposed by Dianne Feinstein, a California Democrat, would harm women because an assault weapon “in the hands of a young woman defending her babies in her home becomes a defense weapon.” She spoke of the “peace of mind” and “courage” a woman derives from “knowing she has a scary-looking gun” when she’s fighting violent criminals.
It is not at all clear where Ms. Trotter gained her insight into confrontations between women and heavily armed intruders, since it is not at all clear that sort of thing happens often. It is tempting to dismiss her notion that an AR-15 is a woman’s best friend as the kooky reflex response of someone ideologically opposed to gun control laws and who, in her case, has also been a vociferous opponent of the Violence Against Women Act, the 1994 law that assists women facing domestic violence.
But it is important to note that Ms. Trotter was chosen to testify by the committee’s Republican members, who will have a big say on what, if anything, Congress does on guns; and that her appearance before the committee was to give voice to the premise, however insupportable and dangerous it may be, that guns make women and children safer — and the more powerful the guns the better.
Ms. Trotter related the story of Sarah McKinley, an 18-year-old Oklahoma woman who shot and killed an intruder on New Year’s Eve 2011, when she was home alone with her baby. The story was telling, but not in the way she intended, as Sheldon Whitehouse, a Rhode Island Democrat, pointed out. The woman was able to repel the intruder using an ordinary Remington 870 Express 12-gauge shotgun, which would not be banned under the proposed statute. She did not need a military-style weapon with a 30-round magazine.
But there is a more fundamental problem with the idea that guns actually protect the hearth and home. Guns rarely get used that way. In the 1990s, a team headed by Arthur Kellermann of Emory University looked at all injuries involving guns kept in the home in Memphis, Seattle and Galveston, Tex. They found that these weapons were fired far more often in accidents, criminal assaults, homicides or suicide attempts than in self-defense. For every instance in which a gun in the home was shot in self-defense, there were seven criminal assaults or homicides, four accidental shootings, and 11 attempted or successful suicides.
The cost-benefit balance of having a gun in the home is especially negative for women, according to a 2011 review by David Hemenway, director of the Harvard Injury Control Research Center. Far from making women safer, a gun in the home is “a particularly strong risk factor” for female homicides and the intimidation of women.
In domestic violence situations, the risk of homicide for women increased eightfold when the abuser had access to firearms, according to a study published in The American Journal of Public Health in 2003. Further, there was “no clear evidence” that victims’ access to a gun reduced their risk of being killed. Another 2003 study, by Douglas Wiebe of the University of Pennsylvania, found that females living with a gun in the home were 2.7 times more likely to be murdered than females with no gun at home.
Regulating guns, on the other hand, can reduce that risk. An analysis by Mayors Against Illegal Guns found that in states that required a background check for every handgun sale, women were killed by intimate partners at a much lower rate. Senator Patrick Leahy, the Judiciary Committee chairman, has used this fact to press the case for universal background checks, to make sure that domestic abusers legally prohibited from having guns cannot get them.
As for the children whose safety Ms. Trotter professes to be so concerned about, guns in the home greatly increase the risk of youth suicides. That is why the American Academy of Pediatrics has long urged parents to remove guns from their homes.
The idea that guns are essential to home defense and women’s safety is a myth. It should not be allowed to block the new gun controls that the country so obviously needs.
