Newtown Dad's Tearful Plea at Senate Gun Hearing

A father who lost his son in the massacre at Sandy Hook Elementary School sobbed as he testified at a Senate hearing today in favor of an assault weapons ban.

Across town Vice President Biden alluded to untold horror of the Newtown tragedy in an appeal for help from the nation's attorneys general.

Despite their emotional appeals, the push for gun reforms championed by the White House and many Democrats faces an uncertain future.

"Jesse was the love of my life," said Neil Heslin, sobbing as he described his 6-year-old son before the Senate Judiciary Committee. "He was the only family I had left. It's hard for me to be here today to talk about my deceased son. I have to. I'm his voice."

Heslin's son, Jesse Lewis, was among the 20 children and six teachers and school administrators murdered at Sandy Hook Elementary in Newtown, Conn. last December. Heslin recounted his last moments with his son when he took him to pick up his favorite, sausage egg and cheese sandwich and hot chocolate before dropping him off at school on the morning of Dec. 14.

"It was 9:04 when I dropped Jesse off. Jesse gave me a hug and a kiss and at that time said goodbye and love you. He stopped and said, I loved mom too." Heslin and his wife are separated.

"That was the last I saw of Jesse as he ducked around the corner. Prior to that when he was getting out of the truck he hugged me and held me and I could still feel that hug and pat on the back and he said everything's going to be ok dad. It's all going to be ok," Heslin said breaking down in tears a second time. "It wasn't ok. I have to go home at night to an empty house without my son."

Heslin was one of eight witnesses testifying at a hearing to back a proposed assault weapons ban. Another witness was Dr. William Begg, a physician who made it to the emergency room the day of the Newtown shooting.

"People say that the overall number of assault weapon deaths is small but you know what? Please don't tell that to the people of Tucson or Aurora or Columbine or Virginia Tech, and don't tell that to the people in Newtown," Begg said as he choked up and people in the crowd clapped. "Don't tell that to the people in Newtown. This is a tipping point. This is a tipping point and this is a public health issue. Please make the right decision."

The Senate Judiciary Committee is set to consider four gun safety measures, including the assault weapons ban, on Thursday. The three other bills aim to stop illegal gun trafficking, enhance safety in schools, and enact universal background checks.

As the hearing unfolded on Capitol Hill, Biden tapped into the stories that Newtown's first responders have shared with him as he urged attorneys general to help the administration push their gun proposals.

"With the press not here, I can tell you what is not public yet about how gruesome it was," Biden said of the massacre's gruesome aftermath at a Washington luncheon. "I met with the state troopers who were on the scene this last week. And the impact on them has been profound. Some of them, understandably, needing some help."

A spokeswoman for Biden could not clarify the non-public information to which he referred. The vice president suggested that what he heard in private conversations should spur lawmakers to enact some measures aimed at curbing gun violence.

Lack of sleep leads to groggy genes: study

WASHINGTON: Lack of sleep has a potentially harmful effect on gene expression, according to a study out Tuesday that sheds light on the link between sleep deficits and a wide range of health conditions.

A sleep deficit -- even just a week's worth -- can have damaging effects on our genes, researchers said in a new study out Tuesday.

Lack of adequate shut-eye had already been linked to conditions from heart disease and cognitive impairment to obesity.

But sleep researcher Derk-Jan Dijk and his fellow researchers have delved into the molecular mechanisms behind the phenomenon, looking at how missed sleep leads to health problems.

They found that a week of sleeping six hours or less a night affects the expression of some 711 genes -- including those involved in inflammation, immunity, and stress responses.

Moreover, compared with test subjects who were allowed to sleep as long as 10 hours a night, those who lacked sleep had irregularities in their genes' circadian rhythms, experiencing a sharp reduction in the number of genes that wax and wane throughout the day and a dampened amplitude for many more.

At the end of the week, the test subjects were kept awake for 40 hours, with blood tests at regular intervals.

The research showed that, for those who had gotten adequate sleep previously, the affects of the sleep deprivation were seven times less than for those already operating under a sleep deficit.

Nearly a third of American workers -- some 40.6 million people -- average six hours or less of sleep a night, according to a 2010 study by the Centers for Disease Control and Prevention.

A normal night's sleep for healthy adults is considered to be between seven and eight hours.

Sony needs help naming its pink balls

The Sony SRS-BTV5 portable speaker features Bluetooth, NFC, and 5-hour battery life.

It's not every day the president of Sony writes a blog post headlined "Help Sony's President Name His Pink Audio Balls."

What balls are we talking about? Today, Sony U.S. President Phil Molyneux took to the company's official blog and asked the Internet to leave a comment with a new name for the anemic-sounding SRS-BTV5 Bluetooth Wireless Mobile Speaker. If he likes the name, he'll push it through as the product's new moniker. The people behind the top five names get free -- ahem -- balls.

"In my 25 years with Sony, we've tended to drift away from some of the more clever and catchy product names like Walkman," Molyneux said in the post. Molyneux noted that setbacks from trademarks, international laws, and focus group testing, as well as packaging considerations, can turn the simple idea of naming a product into a rather difficult endeavor -- an endeavor that in some cases can include more than 600 names from the get-go.

This isn't the first time Molyneux has made a humorous reference to the round speaker. He made a similar statement upon announcing the product at
CES: "I carry my pink balls with me wherever I go." The remark inspired chuckles and confused looks from the crowd media types at the event.

Sony plans black and white variants of the $69 audio ball, which arrive along with the pink version on March 5. I can only imagine the feedback Molyneux would receive if the blog post contained either of two other shades in the title.

The "Help us with a Name" contest runs through March 8.

A History of Balloon Crashes

A hot-air balloon exploded in Egypt yesterday as it carried 19 people over ancient ruins near Luxor. The cause is believed to be a torn gas hose. In Egypt as in many other countries, balloon rides are a popular way to sightsee. (Read about unmanned flight in National Geographic magazine.)

The sport of hot-air ballooning dates to 1783, when a French balloon took to the skies with a sheep, a rooster, and a duck. Apparently, they landed safely. But throughout the history of the sport, there have been tragedies like the one in Egypt. (See pictures of personal-flight technology.)

1785: Pioneering balloonist Jean-Francois Pilatre de Rozier and pilot Pierre Romain died when their balloon caught fire, possibly from a stray spark, and crashed during an attempt to cross the English Channel. They were the first to die in a balloon crash.

1923: Five balloonists participating in the Gordon Bennett Cup, a multi-day race that dates to 1906, were killed when lightning struck their balloons.

1924: Meteorologist C. LeRoy Meisinger and U.S. Army balloonist James T. Neely died after a lightning strike. They had set off from Scott Field in Illinois during a storm to study air pressure. Popular Mechanics dubbed them "martyrs of science."

1995: Tragedy strikes the Gordon Bennett Cup again. Belarusian forces shot down one of three balloons that drifted into their airspace from Poland. The two Americans on board died. The other balloonists were detained and fined for entering Belarus without a visa. (Read about modern explorers who take to the skies.)

1989: Two hot air balloons collided during a sightseeing trip near Alice Springs, Australia. One balloon crashed to the ground killing all 13 people on board. The pilot of the other balloon was sentenced to a two-year prison term for "committing a dangerous act." Until today, this was considered the most deadly balloon accident.

2012: A balloon hit a power line and caught fire in New Zealand, killing all 11 on board. Investigators later determined that the pilot was not licensed to fly and had not taken  proper safety measures during the crash, like triggering the balloon's parachute and deflation system.

2012: A sightseeing balloon carrying 32 people crashed and caught fire during a thunderstorm in the Ljubljana Marshes in Slovenia. Six died; many other passengers were injured.

Senate Votes to Confirm Hagel as Defense Secretary

After a tough two-month battle characterized by tough interrogation and a partisan divide, the Senate voted 58-41 to confirm Chuck Hagel -- President Obama's nominee -- as secretary of defense this afternoon.

Only four Republicans broke party lines to vote in Hagel's favor. They included Sens. Thad Cochran of Mississippi, Richard Shelby of Alabama, Mike Johanns of Nebraska and Rand Paul of Kentucky, though Paul had voted against moving forward with the vote earlier today.

Before that cloture vote to close the debate and bring Hagel's nomination to a vote, Senate Majority Leader Harry Reid, D-Nev., warned Republicans against continuing their partisan fight against the nominee.

"Senate Republicans have delayed for the better part of two weeks for one reason: partisanship," Reid said. "Politically motivated delays send a terrible signal to allies around the world, and they send a terrible signal to tens of thousands of Americans serving in Afghanistan, other parts of world and those valiant people who are serving here in the United States. For the sake of national security, it's time to set aside this partisanship."

The measure to move forward passed by a vote of 71-27. It needed at least 60 votes to pass.

Some Republican senators took the time before the vote to take a last stab at Hagel.

John Cornyn, R-Texas, who was one of 15 senators who sent a letter to Obama last week calling for him to withdraw his nomination of Hagel, said Hagel had proved that he's ill-prepared to assume the defense secretary post.

"There's simply no way to sugar coat it," Cornyn said. "Sen. Hagel's performance before the Senate Armed Services Committee was remarkably inept, and we should not be installing a defense secretary who is obviously not qualified for the job and who holds dangerously misguided views on some of the most important issues facing national security policy for our country. Sen. Hagel is clearly the wrong man for the job."

The Senate returned today after a week off from debating Hagel's pros and cons.

Today's was not the first attempt to bring Hagel's nomination to the floor.

Republicans blocked a cloture vote to confirm Hagel on Valentine's Day, pushing the decision back until after their President's Day recess.

Democrats framed that rejection as a filibuster, while Republicans said they needed another week to discuss the candidate's record.

"This is a very controversial nominee. There is a desire to not end debate now," Sen. Lindsey Graham, R-S.C., said that Thursday. "We feel like come back next week, after the break, unless there is some bombshell I'd be ready to move on to vote."

Ten days later, GOP Sens. Tom Coburn of Oklahoma and John McCain of Arizona predicted the Senate would go through with a vote today.

A group of 15 Republicans sent a letter to Obama last week asking him to withdraw Hagel's nomination. Coburn, one of the senators who signed that letter, said the fight among lawmakers over Hagel's qualifications would weaken him should he become secretary.

"I like Chuck Hagel as an individual, but the fact is, in modern times, we haven't had one defense secretary that's had more than three votes against him," Coburn said on "Fox News Sunday" this weekend. "And you're going to have 40 votes against him, or 35 votes. And that sends a signal to our allies as well as our foes that he does not have broad support in the U.S. Congress, which limits his ability to carry out his job."

McCain did not sign that letter.

Football: Brilliant Bale shines again as Spurs edge thriller

LONDON: Gareth Bale fired Tottenham into third place in the Premier League as his sublime last minute goal capped a majestic performance in a 3-2 win over West Ham at Upton Park on Monday.

Bale has been in the form of his life in recent weeks and the Wales winger added another chapter to his growing legend with a brilliant brace that would surely have been appreciated by Hammers legend Bobby Moore, whose death 20 years ago was marked by a moving pre-match tribute.

Moore, regarded as one of the best defenders in the history of the game, famously captained England to World Cup glory in 1966 and also led West Ham to FA Cup and Cup Winners' Cup triumphs.

But even Moore might have been hard pressed to subdue Bale in this mood.

Bale had given Spurs a first half lead but an Andy Carroll penalty and Joe Cole's strike put West Ham ahead by the hour mark.

Gylfi Sigurdsson came off the bench to equalise and Bale produced a simply remarkable long-range winner to move Tottenham, unbeaten in their last 11 league games, two points clear of Chelsea and four ahead of fifth placed Arsenal, who visit White Hart Lane on Sunday.

"Gareth Bale is unbelievable, a super talent. We have seen him at another level this season," Spurs manager Andre Villas-Boas said.

"He makes the difference in every single game. Players like this assume responsibility at key moments. When you see him joyful on the pitch he gives you rewards.

"The gap to second place is not big and we have a chance to put Arsenal away on Sunday."

Bale added: "It's not about me, it's about the team and we played really well.

"We obviously wanted to get the three points to keep our Champions League hopes alive."

Bale underlined his claims as the best player in the Premier League with yet another moment of magic to put Spurs ahead in the 13th minute.

He was surrounded by West Ham defenders on the edge of the penalty area, but, drifting away from James Collins, he cleverly worked space for a shot and as West Ham's back-four hesitated the Welsh winger drove a low strike past Jussi Jaaskelainen.

That was Bale's 22nd goal for club and country this season, as well as his eighth in his last seven games.

But West Ham responded well to that setback and grabbed an equaliser in the 25th minute.

Kevin Nolan laid the ball off to Carroll in a dangerous position in the penalty area and former West Ham midfielder Scott Parker, lunging in to block, made clear contact on Carroll, forcing referee Howard Webb to give the spot-kick.

England forward Carroll, on loan from Liverpool, stepped up to smash the penalty past Hugo Lloris for his third goal of the season.

Jan Vertonghen almost restored Tottenham's lead in the opening moments of the second half when his cross deflected off Guy Demel and forced Jaaskelainen into a scrambling save.

Jaaskelainen, called into action again from the resulting corner to push away Steven Caulker's towering header, was keeping Spurs at bay almost single-handed.

He turned Sigurdsson's long-range shot onto a post and when the rebound fell to Emmanuel Adebayor, the Hammers goalkeeper leapt to his feet to block the follow-up.

After those escapes, West Ham moved ahead in the 58th minute when Cole collected Joey O'Brien's lofted pass with a fine first touch and turned to bury his shot beyond Lloris.

Tottenham kept pressing and, after Matt Taylor missed a golden chance to extend West Ham's lead, the visitors levelled when Sigurdsson prodded home at the far post from Bale's free-kick.

That set the stage for a pulsating finish and after more heroics from Jaaskelainen, Bale took charge, producing a truely stunning strike from 30 yards to seal the points.

Myo gesture-control armband uses muscle power

The Myo armband uses your muscles for gesture control.

(Credit:
Thalmic Labs)

From "Minority Report" to the Kinect, we've been on a tech quest for touchless gesture control that frees us from the shackles of mice and old-style controllers. We want to get in on the action and use movement to command our digital devices.

Myo from Thalmic Labs takes that gesture-control desire and builds it into an armband you wear on your forearm.

The Myo is available for pre-order. (Click to enlarge.)

Myo)

The Myo uses a combination of motion sensors and muscle activity sensors to track gestures. When you snap your fingers, wave your hand, or point your finger, it translates that movement into a gesture based on the muscles used. An ARM processor and rechargeable batteries power the armband, which communicates with devices using Bluetooth low energy.

The Myo team suggests using the armband to "unleash your inner Jedi," an enormously appealing idea. It could potentially be used to not only control your computer, but also to fly quadrocopters, interface with iOS and
Android, and play video games. The potential is limited only by what developers can create.

The armband will work from the get-go with
Mac and PC computers, enabling control of popular activities like Web browsing, media content, and watching videos. I, for one, am eager to see the gaming abilities showcased.

The Myo can be preordered for $149 and is expected to ship in late 2013. Its success may well depend on the number of applications it will work with.

Details on the device are still pretty thin, but a promotional video shows the direction Thalmic Labs is taking. What do you think? Is this a more appealing technology than existing options like the camera-based Kinect?

Lost Continent Found in Indian Ocean

Evidence of a drowned "microcontinent" has been found in sand grains from the beaches of a small Indian Ocean island, scientists say.

A well-known tourist destination, Mauritius (map) is located about 1,200 miles (2,000 kilometers) off the coast of Africa, east of Madagascar. Scientists think the tiny island formed some nine million years ago from cooling lava spewed by undersea volcanoes.

But recently, researchers have found sand grains on Mauritius that contain fragments of the mineral zircon that are far older than the island, between 660 million and about 2 billion years old.

In a new study, detailed in the current issue of the journal Nature Geoscience, scientists concluded that the older minerals once belonged to a now vanished landmass, tiny bits of which were dragged up to the surface during the formation of Mauritius. (Also see "World's Oldest Rocks Suggest Early Earth Was Habitable.")

"When lavas moved through continental material on the way towards the surface, they picked up a few rocks containing zircon," study co-author Bjørn Jamtveit, a geologist at the University of Oslo in Norway, explained in an email.

Most of these rocks probably disintegrated and melted due to the high temperatures of the lavas, but some grains of zircons survived and were frozen into the lavas [during the eruption] and rolled down to form rocks on the Mauritian surface."

Prehistoric Atlantis

Jamtveit and his colleagues estimate that the lost microcontinent, which they have dubbed Mauritia, was about a quarter of the size of Madagascar (map).

Furthermore, based on a recalculation of how the ancient continents drifted apart, the scientists concluded that Mauritia was once a tiny part of a much larger "supercontinent" that included India and Madagascar, called Rodinia.

The three landmasses "were tucked together in one big continent prior to the formation of the Indian Ocean," Jamtveit said.

But like a prehistoric Atlantis, Mauritia was eventually drowned beneath the waves when India broke apart from Madagascar about 85 million years ago. (Also see "Slimmer Indian Continent Drifted Ten Times Faster.")

Ancient Rocks

Scientists have long suspected that volcanic islands might contain evidence of lost continents, and Jamtveit and his team decided to test this hypothesis during a layover in Mauritius as part of a longer research trip in 1999. (See volcano pictures.)

The stop in tropical Mauritius "was a very tempting thing to do for a Norwegian in the cold month of January," Jamtveit said.

Mauritius was a good test site because it was a relatively young island and, being formed from ocean lava, would not naturally contain zircon, a tough mineral that doesn't weather easily.

If zircon older than 9 million years was found on Mauritius, it would be good evidence of the presence of buried continental material, Jamtveit explained. (See lava and rock pictures.)

At first, the scientists crushed rocks from Mauritius to extract the zircon crystals, but this proved difficult because the crushing equipment contained zircon from other sites, raising the issue of contamination.

"That was a show stopper for a while," Jamtveit said.

A few years later, however, some members of the team returned to Mauritius and this time brought back sand from two different beaches for sampling.

The scientists extracted 20 zircon samples and successfully dated 8 of them by calculating the rate that the elements uranium and thorium inside of the samples slowly break down into lead.

"They all provided much older ages than the age of the Mauritius lavas," Jamtveit said. "In fact they gave ages consistent with the ages of known continental rocks in Madagascar, Seychelles, and India."

Missing Evidence?

Jérôme Dyment, a geologist at the Paris Institute of Earth Physics in France, said he's unconvinced by the work because it's possible that the ancient zircons found their way to the island by other means, for example as part of ship ballast or modern construction material.

"Extraordinary claims require extraordinary evidence, which are not given by the authors so far," said Dyment, who did not participate in the research.

"Finding zircons in sand is one thing, finding them within a rock is another one ... Finding the enclave of deep rocks that, according to the author's inference, bring them to the surface during an eruption would be much more convincing evidence."

Dyment added that if Mauritia was real, evidence for its existence should be found as part of a joint French and German experiment that installed deep-sea seismometers to investigate Earth's mantle around Réunion Island, which is situated about 120 miles (200 kilometers) from Mauritius. (Learn what's inside the Earth.)

"If a microcontinent lies under Réunion, it should be depicted by this experiment," said Dyment, who is part of the project, dubbed RHUM-RUM.

More Dismembered Continents to Be Found?

But Conall Mac Niocaill, a geologist at the University of Oxford in the U.K. who was also not involved in the study, said "the lines of evidence are, individually, only suggestive, but collectively they add up to a compelling story."

The zircons "produce a range of ages, but all yield ages older than 660 million years, and one is almost 2 billion years old," he added.

"There is no obvious source for them in Mauritius, and they are unlikely to have been blown in by the wind, or carried in by human activity, so the obvious conclusion is that the young volcanic lava sampled some older material on their way through the crust."

Based on the new findings, Mac Niocaill and others think other vanished microcontinents could be lurking beneath the Indian Ocean.

In fact, analyses of Earth's gravitational field have revealed other areas in the world's oceans where the rock appears to be thicker than normal and could be a sign of continental crusts.

"We know more about the topography of Mars than we do about the [topography] of the world's ocean floor, so there may well be other dismembered continents out there waiting to be discovered."
