NTT DoCoMo confirms successful 10Gbps wireless test, clears a path to 5G

NTT DoCoMo confirms successful 10Gbps wireless test, paves the way to 5G

No, it's not the world's most conspicuous surveillance van -- it's one of the first steps toward 5G data. NTT DoCoMo has just confirmed that the gear-laden vehicle above successfully conducted a 10Gbps wireless test in Ishigaki this December with the help of the Tokyo Institute of Technology. The dry run relied on frequencies and bandwidth well outside of usual cellular service, in the 11GHz band with 400MHz of spectrum, but proved that it was possible to blow past the speeds of LTE and LTE-Advanced while moving outdoors; the test used 24 antennas to maintain the link. DoCoMo ultimately hopes for similar speed in frequencies over 5GHz, and it's not shy about hoping the technology will define mobile communication as it improves. Although we're not expecting this kind of breakneck performance in a phone for years, it's good to know that 4G isn't necessarily the end of the line.

MONROE, Mich. (AP) ? Most of the menu read like a typical buffet, with soup, salad, turkey, pork and potatoes. But the first offering at the annual Muskrat Dinner in Michigan was distinctive: a pot of the rodent's meat mixed with creamed corn.

"Most beginners are a little hesitant to dive in, especially when they see the carcass laid out on the plate," said Ralph Naveaux, who helped organize the event. "But those of us that have been raised on it, we just adore them. It's almost an addiction."

Members of the Algonquin Club of Detroit and Windsor, Ontario, and other muskrat aficionados ? about 80 in all ? made their way to the Monroe Boat Club, 40 miles south of Detroit, for the recent event.

The history buffs chatted about local lore and heard from a speaker about the War of 1812, but the star of the show was sherry-soaked, boiled and plated.

For these folks, chowing down on muskrat was as natural as seeing the animals scurry around local waters.

Algonquin Club member Robert Lynch, of Kingsville, Ontario, was among those looking to sample a taste of history ? muskrat was a staple of the frontier diet of the region's French settlers.

According to Lynch, muskrat can't really be compared to other kinds of meat.

"I heard somebody say that it tasted like a strong, dark turkey meat. And that would probably be the closest," said Lynch, a 70-year-old retired elementary school teacher. "But there's nothing really to compare to it. It's just different. Some would say it was an acquired taste."

Muskrats, also known locally as "mushrats" or "marsh rabbits," are not rats, but they are members of the rodent family. They eat mostly plants and vegetation, are about 20-25 inches long (including their tails) and weigh between 2 and 5 pounds.

Area residents have been dining on the marsh-dwelling critters for two centuries ? ever since trappers first pared away the animal's odorous musk glands and determined its meat was good to eat.

Charlie Hyde, past president of the Algonquin Club, made his way through the buffet line, sat down and began to dig in.

"Yum, yum," he crowed after taking in a fork-full of muskrat meat and creamed corn.

"This is actually about the best muskrat I've had in about a year. It's the only muskrat I've had in about a year," joked the 67-year-old retired history professor from Royal Oak, Mich.

"Actually, it's very good."

Every year, it seems that technology is inching humanity closer to a world like that of the Jetsons.?Just today, Leap Motion announced a launch date for its long-awaited motion controller. The tiny gadget hooks up to computers (Macs or PCs) and enables the user to control the computer using only hands gestures. The tiny device will set consumers back $80.

According to the company?s blog, the Leap Motion Controller is no bigger than your iPod and 200 times more accurate than any other gesture controller currently on the market. TGDaily reports that this means the Leap Motion Controller, due out in May, will be able to capture gestures as small as 1/100? of a millimeter at 290 frames per second.

The inspiration for the Leap Motion Controller came from the founders? frustration with 3-D modeling.

?Molding clay took 10 seconds in real life but 30 minutes with a computer. The mouse and keyboard were simply getting in the way,? says the company blog. "Since available technology couldn't solve our problems, we created the Leap Motion controller.?

When the Leap Motion Controller is plugged into a USB port, the user can perform a variety of hand signals. Swipe to flip a page, pinch-to-zoom, and even use their hands to play games.

Leap Motion also announced an application market that will offer apps specifically designed for the Leap Motion Controller. Autodesk, Corel Painter, Cut the Rope, and a Wreck-it Ralph racing game will already be available for purchase from the store.

However, as with any new technology, developers must be on board in order to make the hardware and the software work. Airspace won?t have nearly as many apps as the Apple App Store or the Google Play marketplace, at least not for now.

The Atlantic?s Alexis C. Madrigal got a chance to try the Leap Motion Controller.

?I've played with a Leap system and I found it fun and interesting. I'm not sure it will replace your touchscreen or laptop input devices, but at $79, it seems worth trying out,? writes Mr. Madrigal.

The Leap Motion Controller will be available to users through BestBuy. Last month, CNET reported that BestBuy had acquired the exclusive launch rights to the Leap Motion Controller. Those who pre-ordered the gadget before today will receive it for the original asking price of $70 and they will be receiving it on May 13.

BestBuy.com and BestBuy stores will begin to sell the Leap Motion Controller on May 18 and 19, respectively.

China alleges U.S. hacking of Defense Ministry websites

BEIJING (Reuters) - Two major Chinese military websites, including that of the Defense Ministry, were subject to about 144,000 hacking attacks a month last year, almost two-thirds of which came from the United States, the ministry said on Thursday.

This month a U.S. computer security company said that a secretive Chinese military unit was likely behind a series of hacking attacks mostly targeting the United States, setting off a war of words between Washington and Beijing.

China denied the allegations and said it was the victim.

It has now provided some details for the first time of the alleged attacks from the United States.

"The Defense Ministry and China Military Online websites have faced a serious threat from hacking attacks since they were established, and the number of hacks has risen steadily in recent years," said ministry spokesman Geng Yansheng.

"According to the IP addresses, the Defense Ministry and China Military Online websites were, in 2012, hacked on average from overseas 144,000 times a month, of which attacks from the U.S. accounted for 62.9 percent," he said.

The comments were made at a monthly news conference, which foreign reporters are not allowed to attend, and posted on the ministry's website.

Geng said he had noted reports that the United States planned to expand its cyber-warfare capability but that they were unhelpful to increasing international cooperation towards fighting hacking.

"We hope that the U.S. side can explain and clarify this."

The U.S. security company, Mandiant, identified the People's Liberation Army's Shanghai-based Unit 61398 as the most likely driving force behind the hacking. Mandiant said it believed the unit had carried out "sustained" attacks on a wide range of industries.

The hacking dispute adds to diplomatic tension between China and the United States, already strained by Chinese suspicion about Washington's "pivot" back to Asia and arguments over issues from trade to human rights.

Pope recalls 'joy,' difficulties in final audience

VATICAN CITY (AP) ? Pope Benedict XVI bid an emotional farewell Wednesday to his flock on the eve of his retirement, recalling in his final speech as pontiff moments of "joy and light" during his papacy but also times of difficulty when "it seemed like the Lord was sleeping."

An estimated 150,000 people flooded St. Peter's Square for Benedict's last general audience, eager to show their support and bear witness to the final hours of a papacy that will go down in history as the first one in 600 years to end in resignation rather than death.

Benedict clearly enjoyed the occasion, taking a long victory lap around the square in an open-sided car and stopping to kiss and bless half a dozen babies and infants handed to him by his secretary. Seventy cardinals, some tearful, sat in solemn attendance ? then gave him a standing ovation at the end of his speech.

Benedict then made a quick exit, foregoing the typical meet-and-greet session that follows the audience as if to not prolong the goodbye.

Given the historic moment, Benedict also eschewed his typical professorial Wednesday catechism lesson and instead gave a personal, heartfelt final address, explaining once again why he was retiring but assuring his flock of 1.2 billion that he was not abandoning them.

"To love the church means also to have the courage to take difficult, painful decisions, always keeping the good of the church in mind, not oneself," Benedict said to thundering applause.

He noted that a pontiff has no privacy ? neither as pope, nor in his future role as emeritus pope: "He belongs always and forever to everyone, to the whole church."

During his eight years as pope, Benedict said he had had "moments of joy and light, but also moments that haven't been easy ... moments of turbulent seas and rough winds, as has occurred in the history of the church when it seemed like the Lord was sleeping."

But he said he never felt alone, that God always guided him, and he thanked his cardinals and colleagues for their support and for "understanding and respecting this important decision."

The pope's tenure has been beset by the clerical sex abuse scandal, discord over everything from priestly celibacy to women's ordination, and most recently the betrayal by his own butler who stole his private papers and leaked them to a journalist.

Under a bright sun and blue skies, the square was overflowing with pilgrims and curiosity-seekers. Those who couldn't get in picked spots along the main boulevard leading to the square to watch the event on giant TV screens. About 50,000 tickets were requested for Benedict's final master class. In the end, the Vatican estimated that 150,000 people flocked to the farewell.

"It's difficult ? the emotion is so big," said Jan Marie, a 53-year-old Roman in his first years as a seminarian. "We came to support the pope's decision."

With chants of "Benedetto!" erupting often, the mood was far more buoyant than during the pope's final Sunday blessing. It recalled the jubilant turnouts that often accompanied him at World Youth Days and events involving his predecessor, Pope John Paul II.

Benedict has said he decided to retire after realizing that, at 85, he simply didn't have the "strength of mind or body" to carry on.

"I have taken this step with the full understanding of the seriousness and also novelty of the decision, but with a profound serenity in my soul," Benedict told the crowd.

He will meet Thursday morning with cardinals for a final time, then fly by helicopter to the papal residence at Castel Gandolfo south of Rome.

There, at 8 p.m., the doors of the palazzo will close and the Swiss Guards in attendance will go off duty, their service protecting the head of the Catholic Church over ? for now.

Many of the cardinals who will choose Benedict's successor were in St. Peter's Square for his final audience. Those included retired Los Angeles Cardinal Roger Mahony, the object of a grass-roots campaign in the U.S. to persuade him to recuse himself for having covered up for sexually abusive priests. Mahony has said he will be among the 115 cardinals voting for the next pope.

"God bless you," Mahony said when asked by television crews about the campaign.

Also in attendance Wednesday were cardinals over 80, who can't participate in the conclave but will participate in meetings next week to discuss the problems facing the church and the qualities needed in a new pope.

"I am joining the entire church in praying that the cardinal electors will have the help of the Holy Spirit," Spanish Cardinal Julian Herranz, 82, said.

Herranz has been authorized by the pope to brief voting-age cardinals on his investigation into the leaks of papal documents that exposed corruption in the Vatican administration.

Vatican officials say cardinals will begin meeting Monday to decide when to set the date for the conclave.

But the rank-and-file faithful in the crowd weren't so concerned with the future; they wanted to savor the final moments with the pope they have known for years.

"I came to thank him for the testimony that he has given the church," said Maria Cristina Chiarini, a 52-year-old homemaker who traveled by train from Lugo in central Italy with about 60 members of her parish. "There's nostalgia, human nostalgia, but also comfort, because as Christians we have hope. The Lord won't leave us without a guide."

Mineral diversity clue to early Earth chemistry

Feb. 28, 2013 ? Mineral evolution is a new way to look at our planet's history. It's the study of the increasing diversity and characteristics of Earth's near-surface minerals, from the dozen that arrived on interstellar dust particles when the Solar System was formed to the more than 4,700 types existing today. New research on a mineral called molybdenite by a team led by Robert Hazen at Carnegie's Geophysical Laboratory provides important new insights about the changing chemistry of our planet as a result of geological and biological processes.

The work is published by Earth and Planetary Science Letters.

Mineral evolution is an approach to understanding Earth's changing near-surface geochemistry. All chemical elements were present from the start of our Solar System, but at first they formed comparatively few minerals -- perhaps no more than 500 different species in the first billion years. As time passed on the planet, novel combinations of elements led to new minerals.

Molybdenite is the most common ore mineral of the critical metallic element molybdenum. Hazen and his team, which includes fellow Geophysical Laboratory scientists Dimitri Sverjensky and John Armstrong, analyzed 442 molybdenite samples from 135 locations and ages ranging from 2.91 billion years old to 6.3 million years old. They specifically looked for trace contamination of the element rhenium in the molybdenite, because rhenium can be used to use to gauge historical chemical reactions with oxygen from the environment.

They found that concentrations of rhenium, a trace element that is sensitive to oxidation reactions, increased significantly -- by a factor of eight -- over the past three billion years. The team suggests that this change reflects the increasing near-surface oxidation conditions from the Archean Eon more than 2.5 billion years ago to the Phanerozoic Eon less than 542 million years ago. This oxygen increase was a consequence of what's called the Great Oxidation Event, when Earth's atmospheric oxygen levels skyrocketed as a consequence of oxygen-producing photosynthetic microbes.

In addition, they found that the distribution of molybdenite deposits through time roughly correlates with five periods of supercontinent formation, the assemblies of Kenorland, Nuna, Rodinia, Pannotia, and Pangea. This correlation supports previous findings from Hazen and his colleagues that mineral formation increases markedly during episodes of continental convergence and supercontinent assembly and that a dearth of mineral deposits form during periods of tectonic stability.

"Our work continues to demonstrate that a major driving force for mineral evolution is hydrothermal activity associated with colliding continents and the increasing oxygen content of the atmosphere caused by the rise of life on Earth," Hazen said.

Hazen's other co-authors were Joshua Golden, Melissa McMillan, Robert T. Downs, Grethe Hystad, and Ian Goldstein of the University of Arizona; and Holly J. Stein and Aaron Zimmerman of Colorado State University (the former also of the Geological Survey of Norway).

China says US-based hackers target its websites

(AP) ? China's military said Thursday that overseas computer hackers targeted two of its websites an average of 144,000 times per month last year, with almost two-thirds of the attacks originating in the United States.

The claim from Defense Ministry spokesman Geng Yansheng follows accusations last week by American cybersecurity company Mandiant that Chinese military-backed cyberspies infiltrated overseas networks and stole massive amounts of data from U.S. companies and other entities. China denied the allegations, and its military said it has never supported any hacking activity.

Geng told reporters at a monthly news conference that an average of 62.9 percent of the attacks on the Defense Ministry's official website and that of its newspaper, the People's Liberation Army Daily, came from the U.S.

"Like other countries, China faces a serious threat from hacking and is one of the primary victims of hacking in the world," Geng said. "Numbers of attacks have been on the rise in recent years."

Geng attacked the Mandiant report, which blamed hacking on the People's Liberation Army's Shanghai-based Unit 61398, as "unprofessional and not in accordance with the facts." He also criticized the U.S. military's cyber command for impeding international efforts at controlling hacking.

The Mandiant report was widely praised by cybersecurity professionals interviewed by The Associated Press, who said it provided the most detailed picture yet of China's state-sponsored hacking efforts.
