Feathered dino may be world's first bird

The skeleton of a Jurassic dinosaur from China could also be the oldest known bird, scientists report.

The fossil of Aurornis xui was found last year in a museum at the Fossil and Geology Park in Yizhou, China, long after a farmer first dug it up in the Liaoning Province. The feathery specimen represents the most ancient of the avialans, the group that includes birds and their relatives since their split from nonavian dinosaurs.

The research also reconfirms the birdlike fossil Archaeopteryx as an avialan, a classification that was challenged by some recent research. [Avian Ancestors: Dinosaurs That Learned to Fly]

Not everyone agrees that the new specimen is strictly a bird. "In my opinion, it's a bird," study author Pascal Godefroit, a paleontologist at the Royal Belgian Institute of Natural Sciences in Brussels, told Nature News. Even so, he added, "The differences between birds and [nonavian] dinosaurs are very thin."

"Traditionally, we have defined birds as things like Archaeopteryx and closer to things like modern birds," vertebrate paleontologist Luis Chiappe of the Natural History Museum of Los Angeles County, who was not involved in the study, told LiveScience. "If you stick to the definition, this thing is not earliest known bird," Chiappe said, but that's missing the point, he said. What matters, is that it's a very interesting animal that "still helps us understand better the origin of birds," he said.

Aurornis xui was a feathered dinosaur that lived during the Middle Jurassic period about 150 million years ago, analysis shows. It was about 1.6 feet from beak tip to tail tip, and possessed small, sharp teeth and long forelimbs.

The creature probably couldn't fly, Godefroit said, but may have used its wings to glide between trees. The fossil's feathers aren't well-preserved, but the hip bones and other features strongly suggest it was a relative of modern birds, he said.

The researchers assert that Aurornis displaces Archaeopteryx as the oldest avialan, placing Archaeopteryx further along in the avialan lineage. Since Archaeopteryx was a flying creature, its placement among avialans means dinosaurs would have only had to develop powered flight once during evolutionary history.

The new findings also classify another family of birdlike dinosaurs, known as Troodontidae, as a sister group to the avialans. This reshuffling of the bird-dinosaur family tree suggests birds and nonavian dinosaurs diverged in Asia during the Middle to Late Jurassic.

The findings are detailed in the May 30 issue of the journal Nature.

Top 8 new features of Windows 8.1
May 31st 2013, 12:30

Microsoft has offered a window on Windows 8.1, the expected update to its controversial Windows 8 OS. 

Microsoft's corporate VP for Windows Program Management Antoine Leblond wrote in a blog post that "the response to Windows 8 has been substantial...We've learned from customers in how they are using the product and have received a lot of feedback. We've delivered hundreds of updates to the product and to apps. We're just getting started, and the potential ahead is tremendous."

Among the tweaks in Windows 8.1 are "enhancements" in personalization, search, built-in apps, the Windows Store and cloud connectivity.  These are the 8 most intriguing improvements Microsoft announced today.

1. Lock screen slide shows
Microsoft saw Windows 8 users displaying photos of their loved ones on their Lock screens, so they figured, why stop at one photo? In Windows 8.1 users can turn their Lock screen into a slideshow of photos that they've taken straight from their device or from SkyDrive. Or users can take photos right from the Lock screen with the built-in camera.

2. More Start screen options
In Windows 8 you could choose your colors and backgrounds for the Start screen, but now the options have multiplied. Plus, Windows 8.1 adds more tile sizes, so each user can customize his Start screen exactly how he wants. And because Windows 8 users reportedly accidentally moved items on their Start screen, in Windows 8.1 you have to press and hold to move an item.

3. Bing-powered global search
Users can activate the Search charm to find something through Bing, then the results will display everything from apps to Web results to actions you can take, like playing a song or opening a file.

4. Better Snap Views, Built-in Apps
Apparently every built-in Windows 8 app will have some sort of improvement in Windows 8.1. For example, the Photo app add will add some editing features, while the Music app helps you pick and play music.

The ability to run multiple apps simultaneously will also improve, with snap views so you can see more than two apps on your screen and resize those apps, rather than having one main and one docked app as in Windows 8. That way, you can literally build your interface to look exactly how you like. Plus, users can have the same app running on multiple windows, such as Internet Explorer, for improved multitasking capabilities.

5. More comprehensive Windows Store
The Windows Store on Windows 8.1 will emulate Google Play and Apple's App Store, with lists of top free apps, new apps and top picks right on its homepage, so you don't have to dig. Microsoft promises to give more info about each app, so you know exactly what you're getting before tapping Download, and a related apps section gives more options. And if you know exactly what app you're looking for, a search function in the upper right gives you quick access.

6. SkyDrive saving
Files will be saved directly to SkyDrive, and you can access them even when you're offline. Plus, if you log into your device using your Outlook.com account, all your settings and apps will sync.

7. Internet Explorer 11
The only browser built for touch, Internet Explorer 11 takes advantage of Windows 8's key features and offers better touch performance, faster page load times and several other features, such as the ability to adjust the appearance of the modern IE11 to consistently display the address bar and have as many open tabs as you want.

8. Improved mouse/keyboard options
For those who haven't transitioned to touch, Windows 8.1 adds some improvements for those using a traditional keyboard and mouse. Whenever you move your mouse to the bottom left, a Windows tip appears. Plus, you can opt to automatically boot into alternate screens, so, for example, if you'd rather view your Apps page versus all of your tiles, you can boot directly into Apps view.

FOX News: Trip to Mars may mean cancer for astronauts

Trip to Mars may mean cancer for astronauts
May 31st 2013, 12:15

Astronauts who travel to Mars one day could be exposed to dangerous levels of radiation during their trip, even if shielding techniques are used, a new study shows.

When the Mars Science Laboratory launched on Nov. 26, 2011, it began a 350-million-mile trip to the surface of the Red Planet. During its voyage, a group of researchers, including Southwest Research Institute scientist Cary Zeitlin, monitored exactly how much radiation a piece of science hardware on the Mars rover Curiosity was exposed to over the 253-day journey from Earth to Mars.

'It's between a 100 and 1,000 times higher dose [of radiation] than on Earth.'

- Southwest Research Institute scientist Cary Zeitlin

"In space, it's between a 100 and 1,000 times higher dose rate [of radiation] than on Earth," Zeitlin told SPACE.com. "It's highly uncertain what the health risk is from these exposures." [Could Radiation Harm Astronauts Traveling to Mars? (Video)]

Zeitlin, whose study is detailed in the journal Science this week, collected the data with his team by turning on the Radiation Assessment Detector (RAD) instrument while Curiosity was in flight. The instrument was active from 10 days after launch until about three weeks before landing.

Shielding from cosmic rays
By monitoring the variety and strength of each of the energetic particles entering the Mars Science Laboratory's hull, Zeitlin and his team were able to accurately track which particles of radiation got through and which were blocked by the ship's shielding.

If they were to travel to Mars, astronauts would be exposed to two forms of cosmic radiation that don't pose a serious risk on Earth. One of those sources of radiation — galactic cosmic rays — are difficult to shield against and regularly fly through space-faring vessels. On the other hand, the second source of radiation — solar energetic particles — can be at least partially blocked by robust shielding used to protect spaceflyers.

"The rover itself during the trip was surrounded by the equipment used for the entry, descent and landing," Zeitlin said. "RAD was very unevenly shielded. About half was lightly shielded. The heat shield below didn't really provide very much in the way of shielding. But above, there was quite a bit, and on a human inhabited vehicle, you would want it much more uniform."

Worth the risk?
The research could have implications for future NASA missions to Mars. If space agency scientists expect that radiation exposure over the course of a mission will increase an astronaut's risk of developing fatal cancer over his or her lifetime by at least 3 percent, NASA deems the mission too dangerous, Zeitlin said.

Certain people are at higher risk of developing these kinds of radiation-induced cancers: Young women are most at risk, while older men are in less danger. Even with the margin of error built into Curiosity's new results, however, the dose rate of the radiation that any astronaut would receive during the initial and return flights would probably put them over the 3 percent limit, Zeitlin said. [Missions to Mars: Human Occupation of the Red Planet (Infographic)]

Zeitlin and his colleagues estimate that astronauts would be exposed to about 0.66 Sievert (Sv) — the unit scientists use for measuring radiation — of galactic cosmic ray radiation during the round-trip to Mars, not including their time spent on the surface of the Red Planet. About 1 Sv of radiation exposure is usually associated with about a 5 percent bump in fatal-cancer risk later in life.

The dose rate of radiation that the planetary explorers would be exposed to on the surface of Mars would be lower than the amount of cosmic radiation in space. However, it could still be significant, Zeitlin said.

Although this level of radiation might not make astronauts immediately ill, it still could impair their ability to conduct research from Mars. "There is some concern that there could be damage to cognitive ability that would manifest itself in the short run," Zeitlin said.

Future of space travel
Astronauts aboard the International Space Station are exposed to both galactic cosmic rays and solar energetic particles during their six months in orbit, but an astronaut flying to Mars would get a higher dose over a longer period of time.

"Scientists need to validate theories and models with actual measurements, which RAD is now providing. These measurements will be used to better understand how radiation travels through deep space and how it is affected and changed by the spacecraft structure itself," Donald Hassler, a program director at the Southwest Research Institute and principal investigator of the RAD investigation, said in a statement. "The spacecraft protects somewhat against lower-energy particles, but others can propagate through the structure unchanged or break down into secondary particles."

The new findings will allow scientists to use hard data in computer models set up to investigate just how much radiation astronauts could encounter on their journey to another planet. This kind of research could be particularly important for NASA in the coming years, as officials from the space agency gear up to possibly send humans to Mars by the 2030s.

Scientists from the Christian Albrechts University of Kiel in Germany, the German Aerospace Center and NASA also contributed to the new study.

Giant asteroid to sails past Earth
May 31st 2013, 14:30

  • asteroid-1998-qe2

    First radar images of asteroid 1998 QE2 were obtained when the asteroid was about 3.75 million miles (6 million kilometers) from Earth.NASA/JPL-Caltech/GSSR

  • 1998qe2-asteroid-photo

    The Virtual Telescope Project in Italy captured this view of the huge asteroid 1998 QE2 on May 30, 2013.Gianluca Masi/Virtual Telescope Project (www.virtualtelescope.eu)

A huge asteroid is set to cruise by Earth Friday afternoon, making its closest approach to our planet for at least the next two centuries.

Asteroid 1998 QE2 will come within 3.6 million miles of Earth at 4:59 p.m. EDT (2059 GMT) Friday — about 15 times the distance from our planet to the moon.

There's no chance the 1.7-mile-wide 1998 QE2 will hit us, researchers say. That's a good thing, because a strike by such a big space rock would cause catastrophic damage, potentially wiping out our species. [Potentially Dangerous Asteroids (Images)]

'Asteroids of this size have changed the biosphere of our planet in the past.'

- Astronomy magazine columnist Bob Berman

In general, scientists think any asteroid bigger than 0.6 miles could end human civilization if it hit us. For comparison, the object that killed off the dinosaurs 65 million years ago is thought to have been about 6 miles wide.

Asteroid 1998 QE2 won't put on a show for skywatchers. At its closest pass, the space rock will still be 100 times fainter than the dimmest star visible to naked-eye observers under clear and dark skies, experts say.

But several different organizations, including the Slooh Space Telescope and the Virtual Telescope Project, will broadcast live views of the near-Earth asteroid's close approach from professional-quality observatories around the world. You can watch it live right here at FoxNews.com, starting at 4:30 p.m. EDT (2030 GMT).

"It will be fun to actually watch it change position," Astronomy magazine columnist Bob Berman, who will participate in Slooh's show, said in a statement. "As Slooh's Space Cameras image it directly [Friday] afternoon, we will all be reminded that asteroids of this size have changed the biosphere of our planet in the past, and even set the stage for the present dominion of humans."

Scientists are already watching 1998 QE2 closely, in an attempt to learn more about the asteroid's characteristics and orbit. A team of radio astronomers using NASA's Deep Space Network antenna at Goldstone, Calif., for example, just learned that the asteroid is actually a binary system, with a 2,000-foot-wide moon circling the larger space rock.

Researchers plan to use the Goldstone facility as well as the huge Arecibo Observatory in Puerto Rico to watch 1998 QE2 through June 9, NASA officials said.

Asteroid 1998 QE2 was first spotted in August 1998 by astronomers working with MIT's Lincoln Near Earth Asteroid Research program in New Mexico. The space rock's name is not an homage to England's Queen Elizabeth II, or to the famous ocean liner. Rather, it's just the moniker assigned under the established alphanumeric scheme that lays out when asteroids are discovered.

The approaching 1998 QE2 is part of a near-Earth population that likely numbers in the millions. To date, just 10,000 of these relatively close-flying space rocks have been discovered.

FOX News: Could bitcoin go legit?

Could bitcoin go legit?
May 30th 2013, 18:00

  • Bitcoin

The online-only currency known as "bitcoin" is a hit -- one currently trades for about $130 U.S. dollars. But regulators are less excited, fearing money laundering and tax evasion. How can bitcoin go legit?

On May 15, the Department of Homeland Security seized a digital bank account used by "MtGox," the world's largest exchange, where people buy and sell bitcoins. DHS alleged, and a judge agreed, that there is "probable cause"that MtGox is an "unlicensed money service business."If proven, the penalty for operating such a business is a fine and up to 5 years in jail.

Reached by FoxNews.com about whether MtGox has taken steps to comply with U.S. regulations, CEO Mark Karpeles responded that, "Unfortunately we cannot make any official statement at this time."

'I had a good corporate career -- there was no need to jeopardize it by doing something that's illegal.'

- Keyur Mithawala, CEO of bitcoin exchange CampBX

The MtGox incident was a wake-up call for many bitcoin businesses.

"The seizure was kind of the moment where people realized, this is really serious stuff,"said Patrick Murck, general counsel of The Bitcoin Foundation, which represents exchanges and users.

But can they navigate regulations successfully? What would a bitcoin exchange have to do to be legal?

There are currently none that have a seal of approval from the U.S. government, but a few come closer than others. One exchange that touts its regulatory compliance is "CampBX," which is the fourth-largest U.S. dollar/bitcoin exchange and is based in Alpharetta, Georgia.

"We were the first bitcoin exchange to register here in Georgia, and we talked to the state Department of Banking and Finance to make sure we were above-board before we launched the business,"CEO Keyur Mithawala told FoxNews.com.

"I used to work for Cox Communications and Equifax, so I had a good corporate career -- there was no need to jeopardize it by doing something that's illegal,"he explained.

Mithawala estimates that between 60 and 75 percent of his company's expenses are for regulatory compliance. CampBX requires users to submit a government-issued ID and a utility bill before joining, he said.

"When someone submits their documents to us, their name then goes through three government databases that list suspected terrorists and financial criminals. Once the application clears all three databases, that's when we clear their account," Mithawala said.

So far, he said, he knows of just "six or seven"out of thousands of applicants who had failed that check.

Federal regulations then require that every purchase or sale of bitcoins on the site be reported to the government agency known as the "Financial Crimes Enforcement Network" (FinCEN).

"You submit all transactions every quarter,"Mithawala said. "And there are a couple other reports you are also required to file. If you detect any suspicious activity, you are required to file a Suspicious Activity Report, and then there is also a Large Transactions Report."

Mithawala said that he had seen some suspicious activity on the site in the last couple weeks and that it would be reported.

As additional safeguards, CampBX keeps track of users' IP addresses and has a 31-day waiting period before a user's first bank wire deposit to the site clears.

CampBX is currently awaiting approval from federal regulators. The FinCEN website lists CampBX, under its formal legal name "Bulbul Investments,"as having filed an "initial registration."

"It's an application in progress ... I'm confident we will get a positive decision, because we have the right policies in place," he said.

Others have also applied for licenses, including San Francisco bitcoin seller "Coinbase,"which offers a simple interface and is backed by more than $5 million in venture capital funding.

Regulatory compliance does not end with the federal rules, and each state has its own license requirements. Mithawala says that his site is in compliance with Georgia state regulations but that his company is currently reviewing the laws in others, which it also needs to comply with when users are from outside of Georgia.

"We're going to run into a lot of lawyer hours this year,"Mithawala said.

State regulations can be the most onerous.

"I really believe in complying and keeping track of bad guys," said Peter Vessenes, CEO of a start-up called CoinLab, which is attempting to get full regulatory approval before launch. "But with all the different state rules we put in so much more time and energy … than we should have to."

Despite the regulations, technology experts say that they will not prevent people from anonymously using bitcoins for illicit things like buying drugs online. The real-world analogy is cash; the government can tell when it is dispensed by banks, and to whom, but it loses track once it is dispensed.

"Bad people are going to do bad things. Right now the people who do the most bad things do it with cash," Murck of the Bitcoin Foundation said.

Air Force Academy cadets invent search and rescue vehicle of 2045
May 30th 2013, 15:32

    May 13, 2013: Boeing Executive Vice President Dannis Muilenburg, Air Force Academy Superintendent Lt. Gen. Mike Gould, Dean of the Faculty Brig. Gen. Dana Born and others watch a demonstration of a cadet aeronautical engineering project called the "Night Owl" in the Aeronautics Laboratory.

Air Force Academy cadets have captured first place creating a new futuristic vehicle for extracting the wounded from war zones and for conducting search and rescue missions.

Over the past year, the U.S. Military Academy, Naval Academy and Air Force Academy all raced to create a winning design in an annual competition sponsored by Boeing. This year's challenge: design an airplane that could handle MEDEVAC as well as search and rescue.

The competition demands contestants to really push the envelope and truly innovate; the teams were challenged with creating an aircraft that would be state of the art not just today but in 2045.

Boeing issued a set of specific requirements competing teams must achieve, such as being able to complete its mission within and hour and have an operational radius of 100 nautical miles.

Boeing provided $50,000 in funding to the teams for their supplies as well as the materials needed to build two cyclorotors on the Air Force team.

And the winner is….
"The Night Owl" won for best design of a search and rescue and medical evacuation aircraft.

The first place team included nine Air Force Academy cadets: Lillian Pryor, Zach Francis, Wolf Thielmann, Jordan Potterton, Luke Hantla, Kristin Long, Patrick Waters, Trey Cottingham and Zach Adams.

Their design is a futuristic cyclogyro vehicle -- that means it can direct thrust in any direction, allowing for a hover, forward or backward flight.

A cyclorotor looks sort of like the paddle wheel on an old fashioned ferry boat. In this case, their design uses airfoils instead of paddles.

According to the winning team, the Night Owl can hover like a helicopter and is capable of vertical takeoff and landing (VTOL). A very promising design holds potential to not only giving the aircraft significantly higher cruising speeds but to also improving fuel efficiency by a whopping 30 percent over today's helicopters.

Speed is very important in the emergency scenarios of search and rescue or medical evacuation, because seconds can mean the difference between life and death.

The team announced that its cyclogyro design could travel more than twice as fast as current helicopters.

When personnel are conducting an air medical evacuation or search and rescue, they tend to have gloves on making it difficult to use touch screens.

To solve this persistent problem, the team also innovated in developing voice control for the aircraft.  They leveraged existing programs that already exploit voice control and sought to further free up the hands of personnel.

The Air Force Academy announcement noted the team hopes to break records and achieve the first recorded controlled forward flight of a cyclogyro with their Night Owl.

An aircraft like their Night Owl could be incredibly useful not just in war zones, but also for swift medical evacuation in disaster areas on the homeland in tragedies like the recent tornado strikes out West.

This is the Air Force Academy's second win in three years, last year going to the Naval Academy.

    Planetary Resources' crowdfunded telescope will have a camera that can take photos of the spacecraft next to user-submitted pictures, enabling what the company calls the first "space selfies."Planetary Resources

A commercial asteroid-mining company aiming to launch a crowdfunded space telescope raised more than $200,000 on the first day of its campaign.

Planetary Resources, a private venture aiming to mine near-Earth space rocks for water, minerals and other resources, announced Wednesday that it would build and launch a space telescope for public use if it could raise at least $1 million in 33 days.

'If you're a beginner, an 8-year-old, and you want to take a picture of Mars, you'll be able to do it.'

- Planetary Resources co-founder and co-chairman Peter Diamandis

The telescope will be a twin copy of the Arkyd spacecraft the company is developing to detect, track and study asteroids in preparation for its mining mission. A test version of the spacecraft is set for its maiden trial flight in April 2014, while the crowdfunded model would launch in early 2015. [Gallery: Planetary Resources' Asteroid Mission]

The spacecraft's public backers would use it to study celestial objects of their choice. They would also have the option of sponsoring research projects at schools, universities or museums that could use the instrument.

"For me, that's the single most exciting part of this, that it will be available to science classrooms, to astronomy classrooms, and kids will be able to do deep space exploration on this telescope on par with what's being done by NASA and other organizations that control all of the satellites," Brent Spiner, the actor who played Data on the "Star Trek: The Next Generation" television series, said during a webcast to raise funds for the project Wednesday night. "This one will belong to the people."

The project is part of Planetary Resources' plan to make space more accessible to average people, its officials siad.

"I am here to represent the sci-fi crowd, and the line between sci-fi and reality is blurring more and more as time goes on and I think that's what really exciting about this," Spiner said.

Planetary Resources is developing an interface to serve a variety of users, from scientists to kindergarten students.

"If you're a beginner, an 8-year-old, and you want to take a picture of Mars, you'll be able to do it," Planetary Resources co-founder and co-chairman Peter Diamandis said Wednesday during a press event at the Seattle Museum of Flight announcing the campaign."It'll be easy and appropriate for the level of user."

The telescope will also take "space selfies" — self portraits that show the telescope in orbit, with a user-submitted photo displayed on the instrument's screen. A camera mounted on the hull of the spacecraft will snap the photo. Already more than 200 backers have ordered selfies for $25 and above.

"We are putting a webcam on the shoulder of Christopher Columbus as he explored the New World," said Planetary Resources co-founder and co-chairman Eric Anderson. "You are literally going to have the chance to see and feel and listen to what it's like to explore the solar system."

The crowdfunding project, hosted on the Kickstarter website, came about as a way to involve the public in Planetary Resources' mission, which has garnered enthusiastic public support since its announcement in April 2012, its founders said."When we announced the company last April, we really were blown away by the level of interest and excitement," Diamandis said."We were not ready for it."

The company has grand plans for public engagement, beyond the space telescope. "In the future, we're going to be looking at using this crowd that we're developing to help us do data analysis of asteroids, help us develop crowd-sourced software, and even hardware," Diamandis said."Our goal is to democratize the access to space."

But if the crowdfunding campaign fails to reach its $1 million goal by June 30, the company will receive none of the money it has raised.

"All of you out there who believe in this, you've got to put your money where your mouth is," Anderson said. "You've got to help us out,".

UN human rights expert urges moratorium on developing 'killer robots'
May 30th 2013, 15:16

Published May 30, 2013

Associated Press

  • Terminator

GENEVA –  Nations should agree to a moratorium on developing robots for war that can function autonomously before it is too late to stop their use, a U.N. human rights expert warned Thursday.

U.N. special rapporteur Christof Heyns urged a temporary freeze on producing or using so-called killer robots, saying it would give nations time to think through the implications of creating them while "the genie is still in the bottle" technologically.

Programming machines to kill without humans making decisions could encourage more wars and make it more difficult to hold anyone accountable for war crimes, he told reporters in Geneva.

"Time is of the essence," he said of the need to decide now on how to use the robots, before they become a practical reality. "Trying to stop technology is a bit like trying to stop time itself -- it moves on."

Heyns said the technology is quickly emerging and nearly available now that could lend machines the power to autonomously kill humans after "the turn of a switch," but lack the ability to make fine distinctions according to international humanitarian law. "We are pretty close," he said.

In a report to the U.N. Human Rights Council, Heyns urged nations "to declare and implement national moratoria on the production, assembly, transfer, acquisition, deployment and use" of the robots to give time to develop a global framework for their use.

Another big danger of developing these kinds of robots, he said, is that it will make it easier for nations to go to war because of the increasing detachment between people and the decision to kill.

A British museum is about to haul 8 tons of history out of the English Channel -- the only remaining Nazi bomber from the World War II Blitz on London.

The plane, one of a formation of German Dornier Do-17 that Hitler sent to the southeast coast of England in his efforts to blast the country out of World War II, has lain in a shallow grave 60 feet underwater since 1940.

It was lost for decades, buried beneath the time, the tides, and the seafloor of Goodwin Sands, a large sandbank off the coast of Kent County, the last bit of rolling English countryside before Britain gives way to the straits of Dover, 20 or so miles of cold sea, and ultimately France.

'There are no other Dornier 17s left that we're aware of. I really can't stress enough how important this is.'

- Ian Thirsk, head of collections at the RAF Museum

And conservationists battling the weather had hoped to lift the plane out as early as today. It's an historic restoration effort years in the making, said project manager Ian Thirsk, head of collections at the RAF Museum in England.

"We're pretty much on tenterhooks. It's very exciting," Thirsk told FoxNews.com. Unseasonable weather has delayed the actual lift, which will take a few hours and may occur as early as Sunday or Monday, with a decision due Saturday night.

"It's been three years to plan this project, so the last stages are obviously critical," he said.

Sidescan sonar images revealed the silhouette of the craft in 2008, as the shifting sands exposed the perfectly preserved plane for the first time. The Dornier's very existence is remarkable: It's a one of a kind piece of history, he said.

"There are no other Dornier 17s left that we're aware of," Thirsk told FoxNews.com. "I really can't stress enough how important this is."

The Dornier's rarity is an odd fact of the era: The hundreds of fighters that England shot down were smelted during the war and reused, ironically turned into British aircraft to continue the battle against the Germans.

"We've got a Spitfire and a Hurricane and a German Messerschmidt," Peter Dye, Director General RAF Museum, told FoxNews.com earlier this month. "All the other aircraft were sent to smelters and recycled, ironically enough into our aircraft."

"You might say it's environmentally sound," he added wryly.

Once pulled from the waters, exposure to air will immediately begin ot degrade the plane, Thirsk explained. So the RAF Museum, in conjunction with the Port of London Authority, the National Heritage Memorial Fund, and Imperial College London have designed an elaborate process of preservation.

After a special lift raises the plane from the sea floor, it will be doused with sea water and covered with chemicals and gels to preserve it, before the wing section is removed for transportation.

It will then be driven a few hours down the highway -- likely the first time a Nazi craft has navigated England's roads in half a century.

The preservation process involves a months -- or even years-long -- lemon-juice shower, an odd solution devised by the Imperial College's Department of Material Science that strips away the Channel's chemicals and prevents exposure to oxygen.

By washing away the chloride with citric acid, the surface is effectively protected and a barrier to further corrosion built, Dye explained. The process is lengthy, and the entire proceeding will cost roughly half a million pounds (around $750,000). But the uniqueness of the find makes it truly worthwhile, he told FoxNews.com.

"We feel that this is a unique survivor, the only German bomber from the Blitz that's left. And it's hugely important to British national history," he said.

Oldest dinosaur embryos ever discovered?

A dinosaur nest discovery has revealed the most primitive known dinosaur embryos, which are among the oldest ever found.

The eggs belong to Torvosaurus, a T. rex-like predator that stalked the late Jurassic some 150 million years ago. Torvosaurus grew to be around 30 feet long, but the fragmented embryos discovered in Portugal were probably only about 6 inches in length.

'He just stumbled across some eggshells [and found] there was also an entire nest up there.'

- Ricardo Arajo, a doctoral candidate in paleontology at Southern Methodist University

"This is shedding some light on the early stages of the development of these types of dinosaurs," said Ricardo Arajo, a doctoral candidate in paleontology at Southern Methodist University in Texas. [See Photos of Dinosaur Embryos and Hatchlings]

A surprising find
The crushed clutch of eggs was found in 2005 by amateur fossil-hunter and fossil cast-maker Art Walen, who was on an annual vacation to the fossil-rich Lourinh Formation in western Portugal.

"He just stumbled across some eggshells, and he traced the eggshells up the cliffs and he found there were not only isolated eggshells, there was also an entire nest up there," Arajo told LiveScience.

Paleontologists from the Museu da Lourinh excavated the nest, which researchers first assumed belonged to a long-necked sauropod dinosaur. Even in the field, however, the paleontologists began to think they might have something very different on their hands. The eggs' surfaces were ornamented with a strange, almost honeycomb-like pattern that was quite distinct from anything the researchers had ever seen, Arajo said.

Once the specimen was excavated and brought to the museum for preparation, the researchers got another surprise: There were embryo bones mixed in with the crushed eggs.

Such a find is "extremely rare," Arajo said. "There's probably a handful of situations like this in the world."

Dinosaur development
The bones enabled the researchers to link the nest back to a specific species of dinosaur. Torvosaurus was a theropod, a group that includes both Tyrannosaurus rex and modern birds. The specimens are the earliest theropod embryos ever found.

They're also the most primitive, Arajo said. Torvosaurus is on an early branch of the dinosaur family tree, making them "basal theropods," or very early examples of the group. So while other dinosaur embryos (including some found recently in China) date back to earlier eras, Arajo said, the new discoveries are the most primitive in terms of dinosaur evolutionary relationships.

The find reveals some secrets of egg evolution. Modern bird eggs are made up of three layers, Arajo said, and most dinosaur eggs have two layers. The Torvosaurus eggs are so primitive that they have just one layer.

"This is the first evidence for a one-layered eggshell for theropod dinosaurs ever found," Arajo said.

The exceptionally preserved shells are marked by a series of wide, interconnected pores. Pores allow the eggs to "breathe," and their size depends on whether the eggs are exposed to moisture or dry air. The size and shape of the Torvosaurus egg pores suggest they were buried in a moist environment for incubation, Arajo said.

He and his colleagues report the findings May 30 in the journal Scientific Reports.

Egypt's Islamic antiquities suffer from looting, political turmoil

CAIRO –  Cairo, the Arab world's most populated city, is often referred to as an open-air museum of Islamic antiquities and the city of 1,000 minarets -- but its rich history and contributions to Islamic art has languished.

The city has seen some of its most beautiful antiquities looted or neglected over the last two years following the 2011 uprising that ousted the country's longtime ruler Hosni Mubarak. Copper door knockers and lavish fixtures on ancient mosques are among the casualties.

The turmoil that followed the uprising has scared away tourists, drying up vital revenue needed to pay for the upkeep of monuments. Police, who once had wide-reaching powers, are largely unable and at times unwilling to clamp down on criminals or aggressive vendors who overwhelm centuries-old mosques, caravansaries and madrasas with street stalls.

The city and its surrounding suburbs are home to around 20 million people, many of whom are poor and live in slums. Its oldest and often poorest neighborhoods are also home to some of the world's most refined Islamic architecture.

The beauty of the ancient mausoleums carved with precise Islamic calligraphy stands in stark contrast to the exposed red-brick buildings and mounds of trash piled along the streets. An ancient aqueduct that transported running water for the city is now a sort of demographic line separating the city's impoverished slums from main roads.

El-Moez Street is the main avenue of Cairo's Old City, built in the 10th Century by the Fatimids as the capital of a dynasty ruling across North Africa to the Levant. The Fatimids lined it with towering palaces and mosques, as did their successors as Egypt's rulers over the centuries — from the Mamluks to the Ottomans.

Efforts under Mubarak to restore the street and turn it into an open-air museum after years of degradation came to a screeching halt after he was toppled. The street, which once had elegant lighting effects and well-paved sidewalks for pedestrians to take in its history, has returned to being a loud and bustling area for vendors and motorists. Frequent electricity outages in the summer leave the street dark at night.

There are no signs for visitors, for example, explaining that the top floor of a certain building in El-Moez street was a learning center for Islam and art, or how courtyards hidden behind ancient structures may have been used. Such buildings stand alongside parked cars and vendors selling lemons, copper fixtures, cheap trinkets and water pipes.

Also stalled is a project to renovate the aqueduct, which leads from the Nile to the Citadel, the fortress that towers over Cairo first built by Saladin in the 12th Century and is topped with a monumental mosque built by the 19th Century ruler Mohammed Ali.
