Live hologram reveals moving people trapped in a fire

Sandrine Ceurstemont, editor, New Scientist TV

Firefighters can see through smoke thanks to thermal imaging helmets
but now, for the first time, they can also make out moving people trapped behind flames.

Created by Pietro Ferraro and colleagues from the National Institute of Optics in Pozzuoli, Italy, the system produces a live holographic movie that reconstructs motion hidden by a fire. In this video, you can see how an infrared camera fails to capture a person blocked by flames because it relies on a lens to produce an image. The holographic view, shown on the right, reproduces the obscured action by shining infrared laser light at it. The technique records information carried by rays reflected by objects or people, which is then decoded in real time to produce the live movie.

The team plans to make a device that houses both the laser and the holographic camera, allowing the system to be fixed inside buildings or tunnels. In addition to its use in fire search and rescue, the technique could also have biomedical applications, for example to monitor breathing or heartbeat.

Iran tells Zardari pipeline must advance despite US

TEHRAN: Iran's supreme leader Ayatollah Ali Khamenei on Wednesday told the visiting Pakistani president that a much-delayed $7.5 billion gas pipeline project must go ahead despite US opposition.

"The Iran-Pakistan gas pipeline is an important example of Tehran-Islamabad cooperation, and despite hostilities towards the expansion of ties we must overcome this opposition decisively," Khamenei told Asif Ali Zardari, his office reported.

The gas pipeline project is strongly opposed by Tehran's archfoe Washington.

"Accessing safe energy source is the first priority for any country including Pakistan. In this region, the Islamic republic is the only nation that has safe energy resources and we are ready to provide Pakistan its energy needs," the all-powerful Khamenei said.

The pipeline project has run into repeated problems, including Pakistan's difficulty in finding funds and opposition to the project from Washington, which has slapped Iran with a raft of sanctions over its nuclear activities.

The Pakistani media reported last year that Zardari would visit Iran in mid-December 2012, when a final agreement was to have been signed, but the visit was delayed.

In 2010, Iran and Pakistan agreed that Tehran would supply between 750 million cubic feet (21 million cubic metres) and one billion cubic feet per day of natural gas by mid-2015.

Iranian President Mahmoud Ahmadinejad told Zardari that, "building the gas pipeline between Iran and Pakistan is a great and important event, and it serves the two nations' interests," the president's office reported.

"I believe that building this project is very beneficial for both sides and we support all the work carried out so far," Zardari said in talks his Iranian counterpart.

"The international and regional players have tried in vain to prevent an expansion of Iran-Pakistan ties but the people have learnt how to act against enemies of Islam," he was quoted as saying.

Islamabad has said it will pursue the project regardless of US pressure, saying the gas is needed to help Pakistan overcome its energy crisis that has led to debilitating blackouts and suffocated industry.

Iran has almost completed the pipeline work in its territory, but Pakistan has not yet started construction of 780 kilometers (490 miles) of the pipeline on its side, which is said to cost some $1.5 billion.

Sanctions-hit Iran finally agreed to finance one-third of the costs of laying the pipeline through Pakistani territory to Nawabshah, north of Karachi, with the work to be carried out by an Iranian company.

Pakistani officials in mid-December said Iran had promised a $500 million loan and that Islamabad would meet the rest of the cost.

"There are impediments in view of the US opposition to the project but we are determined to complete it to meet our fast-growing energy requirements," said one government official on condition of anonymity.

Tehran has been strangled by a Western oil embargo that has seen its crude exports halve in the past year, while Pakistan has an acute need for energy and plans to produce 20 percent of its electricity from Iranian gas.

Iran has the second largest world gas reserves after Russia and currently produces some 600 million cubic metres a day, almost all of which is consumed domestically due to lack of exports means.

The only foreign client is Turkey, which buys about 30 million cubic metres of gas a day.

Tehran also plans to sell its gas to two other neighbours, Iraq and Syria. The three countries agreed in 2011 to build a pipeline, with the work already started on the Iranian side.

Tim Cook doesn't like Apple's falling share price, either

Apple's iPhone 5.

CNET)

If you're an Apple shareholder and are pretty pissed about the company's recent stock drop, you can at least take comfort in knowing you're not alone.

Apple Chief Executive Tim Cook says today during the electronics giant's annual shareholder meeting that he knows people are upset about the stock drop.

"I don't like it either," Cook said. Nor does the board and management, he added.

But what investors are likely still wondering is what Apple's going to do about it. Shares have tumbled roughly 35 percent from their peak in September, and it's unclear what could spur another run higher. Many investors have become worried about increased competition from the likes of Samsung and others, and some shareholders, like David Einhorn, have demanded that Apple return more cash to investors.

Cook today says the company is focused on the long term and making the very best products. He noted that Apple is working harder than ever and "has some great stuff coming."

Apple shares recently slid 1 percent to $444.29 as investors await more news from the shareholder meeting.

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.

Bring on the Cuts: Some Want the Sequester

Mark Lucas wouldn't mind seeing America's defense budget cut by billions.

"There's quite a bit of waste within the military," Lucas, who serves as Iowa state director for the conservative group Americans for Prosperity (AFP), told ABC News. "Being in there for 10 years, I've seen quite a bit of it."

With the budget sequester set to kick in on Friday, the former Army ranger is among a small chorus of conservatives saying bring on the cuts.

Lucas cited duplicative equipment purchases, military-run golf courses and lavish food on larger bases -- unlike the chow he endured at a combat operations post in Afghanistan with about 120 other soldiers.

"These guys would have very good food, and I'm talking almost like a buffet style, shrimp and steak once a week, ice cream, all this stuff," Lucas said. "They had Burger Kings and Pizza Huts and McDonald's. And I said to myself, 'Do we really need this?'"

Lucas and AFP would like to see the sequester modified, with federal agencies granted more authority to target the cuts and avoid the more dire consequences. But the group wants the cuts to happen.

"We're very supportive of the sequestration cuts but would prefer to see more targeted cuts at the same level," said the group's spokesman, Levi Russell.

As President Obama and his Cabinet members are sounding the sequester alarm bells, AFP's willingness shows that not everyone is running for the hills.

Obama traveled to Norfolk, Va., on Tuesday to speak at a shipyard about cuts and layoffs to defense contractors. In his most recent weekly radio address, he told Americans that the Navy has already kept an aircraft carrier home instead of deploying it to the Persian Gulf. And last week, he spoke before national TV cameras at the White House, warning that first responders would be laid off.

Homeland Security Secretary Jane Napolitano has warned that the sequester will "leave critical infrastructure vulnerable to attacks." Transportation Secretary Ray LaHood has warned that air travel will back up after the Federal Aviation Administration furloughs air traffic controllers. And the heads of 18 other federal agencies told Congress that terrible things will happen unless the sequester is pushed off.

Some Republicans have accused the president of scaremongering to gin up popular support for tax hikes. Obama has warned of calamity and demanded compromise in the next breath, and a few Republicans have rejected this as a false choice.

"I don't think the president's focused on trying to find a solution to the sequester," House Speaker John Boehner told reporters at a press conference on Tuesday. "For 16 months, the president's been traveling all over the country holding rallies, instead of sitting down with Senate leaders in order to try to forge an agreement over there in order to move the bill."

After Obama spoke to governors at the this week, Republican Louisiana Gov. Bobby Jindal told ABC News' Jonathan Karl outside the White House that the president is exaggerating the sequester's consequences.

"He's trying to scare the American people," Jindal said. "He's trying to distort the impact."

Giant laser creates an artificial star to clear the sky

Flora Graham, editor, newscientist.com

(Image: ESO)

It looks like a Stormtrooper's snapshot of the Death Star's superlaser in action, but this is actually a photo of a new laser that's just completed testing at the Very
Large Telescope in Chile.

The laser shoots 90 kilometres into the atmosphere, where it
interacts with the 10-kilometre-thick layer of sodium atoms left around our
planet by meteoroid impacts. The laser makes the sodium fluoresce, producing a bright
point of light that acts as an artificial star.

Astronomers use this pinpoint as a reference to monitor atmospheric turbulence in the telescope's line of sight. Deformable
mirrors in the telescope shift in response to these measurements, compensating for the atmosphere's distortions and creating much
sharper images of the heavenly bodies beyond.

Researchers say that the new laser is more flexible and
reliable than the previous
one, which is being retired after six years of service.

"When we started developing these lasers, everyone said our
goal was nearly impossible - even many of the other experts," says Domenico
Bonaccini Calia of the European Southern
Observatory (ESO), which runs the telescope.

Calia calls the new laser a "breakthrough" and hopes to share the technology "with the wider community". We hope that doesn't include moon-sized battle stations.

Portugal may get more time to cut deficit: prime minister

LISBON: Portugal's prime minister on Tuesday said his country may be granted more time to meet its fiscal targets as the implementation of its international bailout was under review.

"There is a possibility of getting one year more to adjust the state deficit and it is very likely that this is up for discussion", Pedro Passos Coelho said as the so-called Troika of public creditors -- the European Union, the European Central Bank and the International Monetary Fund -- on began its latest review of the country's finances.

Portugal was granted a financial rescue package worth 78 billion euros ($103 billion) in May 2011, in exchange for a pledge to straighten out its finances via austerity measures and economic reforms.

Last year the Troika gave eased Portugal's fiscal targets given the recession in the country and across much of the eurozone.

Lisbon now has to reduce its public deficit to 4.5 percent of GDP this year, instead of bringing it back within the EU ceiling of 3.0 percent of GDP.

The government has recently conceded it may be impossible for it to reach even the revised targets given the continued recession.

On Sunday, Finance Minister Vitor Gaspar said the economy is expected to contract around 2 percent this year, or double that of its previous forecast, and said he hopes the European Commission will give Portugal another year to reach the 3.0 percent target.

Passos Coelho said his country would like to "finish the (rescue) programme in June 2014 and we will neither ask for more time or more money."

Google's Andy Rubin: "No plans" to open Android stores

Google Android chief Andy Rubin

So, last week an "extremely reliable source" told blog 9to5 Google there was big news coming: Google was planning to build standalone retail stores in the U.S. to sell Android devices, and the first outlets might even be open in major metropolitan areas in time for the holidays.

Andy Rubin, who heads up Google's
Android business and also qualifies as an extremely reliable source when it comes to this particular company, offered a different appraisal during a meeting with reporters in Barcelona today during Mobile World Congress. "Google has no plans, and we have nothing to announce," he said, and he suggested that changes in customer behavior recently have undercut the traditional rationale for a traditional retail outlet.

"A few years ago, consumers needed to touch and feel devices, but these days they can often get the information they need to make a purchase decision by talking to friends and reading reviews," he told reporters. "They don't have to go in the store and feel it anymore."

Rubin's nyet echoed a similar statement last December, when Google Shopping head Sameer Samat told AllThingsD that the company "had no aspirations to open a store."

Of course, aspirations change and companies are always revisiting old assumptions as conditions change. What with Google pushing into new areas with
Google Glass and its recently announced Chromebook Pixel notebook, here's fodder for the argument that it's premature to perform last rites on the rumor: Both are premium priced products whose success in the market would be helped by knowledgeable salespeople -- in much the same way that Apple has used its stores so expertly to sell its myriad lines. And like Apple, Google has the resources to invest should it ever decide this is the right direction. Truth be told, however, making a successful go of it at retail is as hard as it's ever been. Apple is the exception in the technology industry's history of single-store brands sold through company owned outlets, a chronicle chockablock with high-profile failures, including IBM,
CompuAdd and Gateway, and Dell, among others.

Sharks Warn Off Predators By Wielding Light Sabers

Diminutive deep-sea sharks illuminate spines on their backs like light sabers to warn potential predators that they could get a sharp mouthful, a new study suggests.

Paradoxically, the sharks seem to produce light both to hide and to be conspicuous—a first in the world of glowing sharks. (See photos of other sea creatures that glow.)

"Three years ago we showed that velvet belly lanternsharks [(Etmopterus spinax)] are using counter-illumination," said lead study author Julien Claes, a biologist from Belgium's Catholic University of Louvain, by email.

In counter-illumination, the lanternsharks, like many deep-sea animals, light up their undersides in order to disguise their silhouette when seen from below. Brighter bellies blend in with the light filtering down from the surface. (Related: "Glowing Pygmy Shark Lights Up to Fade Away.")

Fishing the 2-foot-long (60-centimeter-long) lanternsharks up from Norwegian fjords and placing them in darkened aquarium tanks, the researchers noticed that not only do the sharks' bellies glow, but they also had glowing regions on their backs.

The sharks have two rows of light-emitting cells, called photophores, on either side of a fearsome spine on the front edges of their two dorsal fins.

Study co-author Jérôme Mallefet explained how handling the sharks and encountering their aggressive behavior hinted at the role these radiant spines play.

"Sometimes they flip around and try to hit you with their spines," said Mallefet, also from Belgium's Catholic University of Louvain. "So we thought maybe they are showing their weapon in the dark depths."

To investigate this idea, the authors analyzed the structure of the lanternshark spines and found that they were more translucent than other shark spines.

This allowed the spines to transmit around 10 percent of the light from the glowing photophores, the study said.

For Predators' Eyes Only

Based on the eyesight of various deep-sea animals, the researchers estimated that the sharks' glowing spines were visible from several meters away to predators that include harbor seals (Phoca vitulina), harbor porpoises (Phocoena phocoena), and blackmouth catsharks (Galeus melastomus).

"The spine-associated bioluminescence has all the characteristics to play the right role as a warning sign," said Mallefet.

"It's a magnificent way to say 'hello, here I am, but beware I have spines,'" he added.

But these luminous warning signals wouldn't impede the sharks' pursuit of their favorite prey, Mueller's bristle-mouth fish (Maurolicus muelleri), the study suggested. These fish have poorer vision than the sharks' predators and may only spot the sharks' dorsal illuminations at much closer range.

For now, it remains a mystery how the sharks create and control the lights on their backs. The glowing dorsal fins could respond to the same hormones that control the belly lights, suggested Mallefet, but other factors may also be involved.

"MacGyver" of Bioluminescence

Several other species use bioluminescence as a warning signal, including marine snails (Hinea brasiliana), glowworms (Lampyris noctiluca) and millipedes (Motyxia spp.).

Edith Widder, a marinebiologist from the Ocean Research and Conservation Association who was not involved in the current study, previously discovered a jellyfish whose bioluminescence rubs off on attackers that get too close.

"It's like paint packages in money bags at banks," she explained.

"Any animal that was foolish enough to go after it," she added "gets smeared all over with glowing particles that make it easy prey for its predators."

Widder also points out that glowing deep-sea animals often put their abilities to diverse uses. (Watch: "Why Deep-Sea Creatures Glow.")

"There are many examples of animals using bioluminescence for a whole range of different functions," she said.

Mallefet agrees, joking that these sharks are the "MacGyver of bioluminescence."

"Just give light to this shark species and it will use it in any possible way."

And while Widder doesn't discount the warning signal theory, "another possibility would be that it could be to attract a mate."

Lead author Julien Claes added by email, "I also discovered during my PhD thesis that velvet belly lanternsharks have glowing organs on their sexual parts."

And that, he admits, "makes it very easy, even for a human, to distinguish male and female of this species in the dark!"

The glowing shark study appeared online in the February 21 edition of Scientific Reports.

'93 WTC Bombing Crushed Lives, Not Memories

Edward Smith remembers vividly the call from the morgue 20 years ago today, that his pregnant wife had died in the World Trade Center bombing hours before she was supposed to start her maternity leave.

"It seems like kind of yesterday sometimes," he told ABC News, "but it seems like a long time ago, too."

Today marks the 20th anniversary of the 1993 WTC bombing, which was overshadowed eight years later by the 9/11 attacks. Six people died and about 1,000 were injured after terrorists detonated a truck bomb in the parking garage of the World Trade Center's North Tower Feb. 26, 1993.

Four of the six killed -- Robert Kirkpatrick, 61, Stephen A. Knapp, 47, William Macko, 57, and Monica Rodriguez Smith, 35 -- were employees of the Port Authority of New York and New Jersey, which owned the buildings. John DiGiovanni, 45, a dental-supply salesman visiting the World Trade Center, and Wilfredo Mercado, 37, a purchasing agent for Windows on the World restaurant, also died.

To commemorate the event, ABC News spoke with several people affected by the bombing -- a widower, a former Port Authority executive director, a plaintiff's attorney and a jury foreman -- to illustrate how the bombing resonates 20 years later.

September 11: World Trade Center Time Lapse Watch Video

Edward Smith, 50, remembers where he was Feb. 26, 1993, when he heard the news.

"I was up in Boston, and I had heard there was a fire at the [World] Trade Center," Smith told ABCNews.com last week. "I turned the TV on, and eventually heard there was an actual bombing, and drove down as quickly as I could."

Smith said he couldn't reach his wife, Monica Rodriguez Smith, a secretary for a mechanical supervisor for the Port Authority of New York and New Jersey who worked in the World Trade Center, for "hours and hours."

He said he didn't hear from her or anything about her until he contacted the New York City morgue at 11:30 p.m. that evening.

"Obviously, I was informed that I should come there," Smith said.

He and his wife had been married for a little more than three years, he said, and Feb. 26 was to be Monica's last day of work before she went on maternity leave. They were expecting their first child, a boy, to be named Eddie.

"She had worked at the Port Authority for at least 12 years," Smith said. "And she had just gotten an award for never having a sick day. That was a little thing you remember."

Smith said the World Trade Center was where he met his wife the first time.

"I was a sales guy, selling to the Port Authority, and she was the admin [secretary] for one of the guys," he said. "For the first two years, she wouldn't go out with me.

"She said, 'Do you know how many knuckleheads come in here and ask me out? What makes you different?'" Smith recalled Monica's saying.

It took her two years to go out on a date with him, Smith said.

The couple tied the knot Aug. 31, 1990. Smith said he even bought the house in which he grew up on Long Island to raise their family.

But after the events of Feb. 26, 1993, Smith said, it was hard to stay in New York. Shortly after the bombing, he moved to Arizona and later to California.

"There were too many reminders, it was too much," he said.

Smith now resides in Phoenix, but makes a trip to New York every year for the memorial in February.
This year is no exception.

"It's kind of an interesting feeling," he said of the 20-year anniversary. "It seems like kind of yesterday sometimes, but it seems like a long time ago, too."
