Space gold rush should not be a free-for-all

We need a consensus on regulations surrounding space mining if it’s to enrich us all

EVER since we took our first steps out of Africa, human exploration has been driven by the desire to secure resources. Now our attention is turning to space.

The motivation for deep-space travel is shifting from discovery to economics. The past year has seen a flurry of proposals aimed at bringing celestial riches down to Earth. No doubt this will make a few billionaires even wealthier, but we all stand to gain: the mineral bounty and spin-off technologies could enrich us all.

But before the miners start firing up their rockets, we should pause for thought. At first glance, space mining seems to sidestep most environmental concerns: there is (probably!) no life on asteroids, and thus no habitats to trash. But its consequences – both here on Earth and in space – merit careful consideration.

Part of this is about principles. Some will argue that space's "magnificent desolation" is not ours to despoil, just as they argue that our own planet's poles should remain pristine. Others will suggest that glutting ourselves on space's riches is not an acceptable alternative to developing more sustainable ways of earthly life.

History suggests that those will be hard lines to hold, and it may be difficult to persuade the public that such barren environments are worth preserving. After all, they exist in vast abundance, and even fewer people will experience them than have walked through Antarctica's icy landscapes.

There's also the emerging off-world economy to consider. The resources that are valuable in orbit and beyond may be very different to those we prize on Earth (see "Space miners hope to build first off-Earth economy"). Questions of their stewardship have barely been broached – and the relevant legal and regulatory framework is fragmentary, to put it mildly.

Space miners, like their earthly counterparts, are often reluctant to engage with such questions. One speaker at last week's space-mining forum in Sydney, Australia, concluded with a plea that regulation should be avoided. But miners have much to gain from a broad agreement on the for-profit exploitation of space. Without consensus, claims will be disputed, investments risky, and the gains made insecure. It is in all of our long-term interests to seek one out.

US sailors jailed for Okinawa rape: report

TOKYO: Two US sailors who raped a Japanese woman in Okinawa last October, sparking island-wide anger, were on Friday jailed for nine and 10 years, a report said.

The Naha District Court in Okinawa said Christopher Browning, 24, should go to prison for 10 years while Skyler Dozierwalker, 23, should serve nine, Jiji Press reported.

Browning and Dozierwalker, who were not stationed in Okinawa, had been drinking on the evening of the attack, which took place on the street and left the unidentified woman with neck injuries.

During an earlier court appearance the two men had admitted the offence, which caused outrage on the sub-tropical islands and beyond, and led to a nationwide night-time curfew on all US military personnel in Japan.

Despite the curfew, misconduct involving US servicemen, much of it drunken, has continued to fuel anti-US sentiment in communities with bases.

Wary of yet another public relations disaster, the US moved quickly to try to lower the temperature in the immediate aftermath of the rape, with ambassador John Roos holding a special news conference at which he appeared visibly angry and upset.

"The United States will cooperate in every way possible with the Japanese authorities to address this terrible situation."

"I understand the anger that many people feel with respect to this reported incident," he said. "I have a 25-year-old daughter myself, so this is very personal to me."

The attack came amid already high tensions in Okinawa, which saw demonstrations last year against the US deployment to the island of the tilt-rotor Osprey aircraft.

The aircraft's perceived poor safety record has been picked over in Japanese media and by local opponents, but commentators say it is a proxy issue and resentment over what many see as an unfair burden is at the root of objections.

Okinawa is the reluctant host to more than half of the 47,000 American service personnel in Japan, and the crimes, noise and risk of accidents associated with their bases regularly provoke ire in the local community.

In 1995 the gang rape of a 12-year-old Okinawan girl by US servicemen sparked mass protests resulting in a US-Japan agreement to reduce the huge US military presence on the Okinawan chain.

Okinawans say other parts of Japan should take more of the burden and want bases closed or reduced in size.

Google compression algorithm Zopfli may lead to faster Internet

Google has released a new data compression algorithm it hopes will make the Internet faster for everyone.

Dubbed Zopfli, the open-source algorithm will accelerate data transfer speeds and reduce Web page load times by compressing content up to 8 percent smaller than the zlib software library, Google said in a company blog post today. Named after a Swiss bread recipe, the new algorithm is an implementation of the Deflate algorithm, which is used in the ZIP archive format, as well as in gzip file compression.

"The higher data density is achieved by using more exhaustive compression techniques, which make the compression a lot slower, but do not affect the decompression speed," said Lode Vandevenne, a Zurich-based software engineer who implemented Zopfli as part of this 20 percent time activity.

Zopfli is a compression-only library, meaning that existing software can decompress the data. It is also bit-stream compatible with gzip, ZIP, PNG, and HTTP requests, among others.

"The smaller compressed size allows for better space utilization, faster data transmission, and lower web page load latencies," he said, adding that mobile users will benefit from the smaller compression in the form of lower data transfer rates and reduced battery use.

Because the amount of CPU time required for compression is two to three orders of magnitude more than zlib, Google believes Zopfli is best suited for applications where data is compressed once and but delivered many times over -- such as static content for the Web.

Scarred Duckbill Dinosaur Escaped T. Rex Attack

A scar on the face of a duckbill dinosaur received after a close encounter with a Tyrannosaurus rex is the first clear case of a healed dinosaur wound, scientists say.

The finding, detailed in the current issue of the journal Cretaceous Research, also reveals that the healing properties of dinosaur skin were likely very similar to that of modern reptiles.

The lucky dinosaur was an adult Edmontosaurus annectens, a species of duckbill dinosaur that lived in what is today the Hell Creek region of South Dakota about 65 to 67 million years ago. (Explore a prehistoric time line.)

A teardrop-shaped patch of fossilized skin about 5 by 5 inches (12 by 14 centimeters) that was discovered with the creature's bones and is thought to have come from above its right eye, includes an oval-shaped section that is incongruous with the surrounding skin. (Related: "'Dinosaur Mummy' Found; Have Intact Skin, Tissue.")

Bruce Rothschild, a professor of medicine at the University of Kansas and Northeast Ohio Medical University, said the first time he laid eyes on it, it was "quite clear" to him that he was looking at an old wound.

"That was unequivocal," said Rothschild, who is a co-author of the new study.

A Terrible Attacker

The skull of the scarred Edmontosaurus also showed signs of trauma, and from the size and shape of the marks on the bone, Rothschild and fellow co-author Robert DePalma, a paleontologist at the Palm Beach Museum of Natural History in Florida, speculate the creature was attacked by a T. rex.

It's likely, though still unproven, that both the skin wound and the skull injury were sustained during the same attack, the scientists say. The wound "was large enough to have been a claw or a tooth," Rothschild said.

Rothschild and DePalma also compared the dinosaur wound to healed wounds on modern reptiles, including iguanas, and found the scar patterns to be nearly identical.

It isn't surprising that the wounds would be similar, said paleontologist David Burnham of the University of Kansas Biodiversity Institute, since dinosaurs and lizards are distant cousins.

"That's kind of what we would expect," said Burnham, who was not involved in the study. "It's what makes evolution work—that we can depend on this."

Dog-Eat-Dog

Phil Bell, a paleontologist with the Pipestone Creek Dinosaur Initiative in Canada who also was not involved in the research, called the Edmontosaurus fossil "a really nicely preserved animal with a very obvious scar."

He's not convinced, however, that it was caused by a predator attack. The size of the scar is relatively small, Bell said, and would also be consistent with the skin being pierced in some other accident such as a fall.

"But certainly the marks that you see on the skull, those are [more consistent] with Tyrannosaur-bitten bones," he added.

Prior to the discovery, scientists knew of one other case of a dinosaur wound. But in that instance, it was an unhealed wound that scientists think was inflicted by scavengers after the creature was already dead.

It's very likely that this particular Edmontosaurus wasn't the only dinosaur to sport scars, whether from battle wounds or accidents, Bell added.

"I would imagine just about every dinosaur walking around had similar scars," he said. (Read about "Extreme Dinosaurs" in National Geographic magazine.)

"Tigers and lions have scarred noses, and great white sharks have got dings on their noses and nips taken out of their fins. It's a dog-eat-dog world out there, and [Edmontosaurus was] unfortunately in the line of fire from some pretty big and nasty predators ... This one was just lucky to get away."

Mysterious Escape

Just how Edmontosaurus survived a T. rex attack is still unclear. "Escape from a T. rex is something that we wouldn't think would happen," Burnham said.

Duckbill dinosaurs, also known as Hadrosaurs, were not without defenses. Edmontosaurus, for example, grew up to 30 feet (9 meters) in length, and could swipe its hefty tail or kick its legs to fell predators.

Furthermore, they were fast. "Hadrosaurs like Edmontosaurus had very powerful [running] muscles, which would have made them difficult to catch once they'd taken flight," Bell said.

Duckbills were also herd animals, so maybe this one escaped with help from neighbors. Or perhaps the T. rex that attacked it was young. "There's something surrounding this case that we don't know yet," Burnham said.

Figuring out the details of the story is part of what makes paleontology exciting, he added. "We construct past lives. We can go back into a day in the life of this animal and talk about an attack and [about] it getting away. That's pretty cool."

Sequestration: Surrender Is in the Air

The budget ax is about to fall, and there's little lawmakers in Washington are doing to stop it.

Despite a parade of dire warnings from the White House, an $85 billion package of deep automatic spending cuts appears poised to take effect at the stroke of midnight on Friday.

The cuts – known in Washington-speak as the sequester – will hit every federal budget, from defense to education, and even the president's own staff.

On Capitol Hill, Senate Democrats and Republicans each staged votes Thursday aimed at substituting the indiscriminate across-the-board cuts with more sensible ones. Democrats also called for including new tax revenue in the mix. Both measures failed.

Lleaders on both sides publicly conceded that the effort was largely for show, with little chance the opposing chamber would embrace the other's plan. They will discuss their differences with President Obama at the White House on Friday.

"It isn't a plan at all, it's a gimmick," Senate Minority Leader Mitch McConnell, R-Ky., said today of the Democrats' legislation.

"Republicans call the plan flexibility" in how the cuts are made, said Senate Majority Leader Harry Reid. "Let's call it what it is. It is a punt."

The budget crisis is the product of a longstanding failure of Congress and the White House to compromise on plans for deficit reduction. The sequester itself, enacted in late 2011, was intended to be so unpalatable as to help force a deal.

Republicans and Democrats, however, remain gridlocked over the issue of taxes.

Obama has mandated that any steps to offset the automatic cuts must include new tax revenue through the elimination of loopholes and deductions. House Speaker John Boehner and the GOP insist the approach should be spending cuts-only, modifying the package to make it more reasonable.

"Do we want to close loopholes? We sure do. But if we are going to do tax reform, it should focus on creating jobs, not funding more government," House Speaker John Boehner said, explaining his opposition to Obama's plan.

Boehner, McConnell, Reid and House Minority Leader Nancy Pelosi will huddle with Obama at the White House on Friday for the first face-to-face meeting of the group this year.

"There are no preconditions to a meeting like this," White House spokesman Jay Carney said today. "The immediate purpose of the meeting is to discuss the imminent sequester deadline and to avert it."

Even if the leaders reach a deal, there's almost no chance a compromise could be enacted before the deadline. Lawmakers are expected to recess later today for a long weekend in their districts.

What will be the short-term impact of the automatic cuts?

Officials say it will be a gradual, "rolling impact" with limited visible impact across the country in the first few weeks that the cuts are allowed to stand.

Over the long term, however, the Congressional Budget Office and independent economic analysts have warned sequester could lead to economic contraction and possibly a recession.

"This is going to be a big hit on the economy," Obama said Wednesday night.

"It means that you have fewer customers with money in their pockets ready to buy your goods and services. It means that the global economy will be weaker," he said. "And the worst part of it is, it's entirely unnecessary."

Both sides say that if the cuts take effect, the next best chance for a resolution could come next month when the parties need to enact a new federal budget. Government funding runs out on March 27, raising the specter of a federal shutdown if they still can't reach a deal.

"As we anticipate an across-the-board budget cuts across our land, we still expect to see your goodness prevail, O God, " Senate Chaplain Barry Black prayed on the Senate floor this morning, "and save us from ourselves."

Resale prices of private homes rebound in January

SINGAPORE: Prices of resale private homes rebounded in January, rising 0.3 per cent, reversing the previous month's 0.2 per cent decline, according to the Singapore Residential Price Index flash estimates published by the Institute of Real Estate Studies at the National University of Singapore.

The increase in January was led by price growth in the small unit segment, defined as homes below 506 square feet.

In January, prices of small units rose 2.6 per cent, reversing a 0.7 per cent fall in December.

Prices of resale homes located in the central region also climbed by 0.7 per cent in January, following a 1.5 per cent decrease in the previous month.

Meanwhile, the only segment that registered a price drop last month was homes outside the central area.

Prices fell 0.1 per cent in January, compared with a 0.8 per cent increase in December.

Viddy doubles length of clips, adds video enhancement tools

Viddy's new iOS app interface.

Social video startup video has released a new iOS app with a bevy of new features to help users enhance the videos they produce and stave off Twitter's upstart video-sharing app Vine.

Debuting this evening in Apple's App Store, the new app doubles the size of videos users can upload from 15 seconds to 30 seconds, as well as adding the Vine-like ability to pause recording to splice together segments into a single clip. The app also adds 15 new video filters, licensed music tracks from popular artists that can be added to videos, and stop-motion functionality that adjusts video frame rates.

Viddy, which is sometimes referred to as the Instagram of video, also social discovery tools to help users find and share videos that are important to them. The update adds a section with curated video categories and trending topics. A geo-centric feed spotlights videos from specific regions, while another feed focuses on user interests and preferences.

In another Twitter-like feature, Viddy will add a verified user program for celebrities, public figures, and company brands.

The new video comes in the wake of corporate upheaval at the Venice, Calif.-based startup. The company, which claims 40 million users, revealed earlier this week that it had laid off a dozen employees, or about a third of its work force. The cuts came less than a month after the firing of co-founder and CEO Brett O'Brien, who was rumored to have turned down a buyout offer from Twitter, which ended up buying Vine and launching its app last month.

Why African Rhinos Are Facing a Crisis

The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."

Arias Prosecutor Too Combative, Experts Say

He has barked, yelled, been sarcastic and demanded answers from accused murderer Jodi Arias this week.

And in doing so, prosecutor Juan Martinez and his aggressive antics may be turning off the jury he is hoping to convince that Arias killed her ex-boyfriend Travis Alexander in June 2008, experts told ABCNews.com today.

"Martinez is his own worst enemy," Mel McDonald, a prominent Phoenix defense attorney and former judge, told ABC News. "He takes it to the point where it's ad nauseam. You have difficulty recognizing when he's driving the point home because he's always angry and pushy and pacing around the courtroom. He loses the effectiveness, rather than build it up."

"He's like a rabid dog and believes you've got to go to everybody's throat," he said.

"If they convict her and give her death, they do it in spite of Juan, not because of him," McDonald added.

Martinez's needling style was on display again today as he pestered Arias to admit that she willingly participated in kinky sex with Alexander, though she previously testified that she only succumbed to his erotic fantasies to please him.

Arias, now 32, and Alexander, who was 27 at the time of his death, dated for a year and continued to sleep together for another year following their break-up.

Arias drove to his house in Mesa, Ariz., in June 2008, had sex with him, they took nude photos together and she killed him in his shower. She claims it was in self-defense. If convicted, Arias could face the death penalty.

Martinez also attempted to point out inconsistencies in her story of the killing, bickering with her over details about her journey from Yreka, Calif., to Mesa, Ariz., including why she borrowed gas cans from an ex-boyfriend, when she allegedly took naps and got lost while driving, and why she spontaneously decided to visit Alexander at his home in Mesa for a sexual liaison.

"I want to know what you're talking about," Arias said to Martinez at one point.

"No, I'm asking you," he yelled.

Later, he bellowed, "Am I asking you if you're telling the truth?"

"I don't know," Arias said, firing back at him. "Are you?"

During three days of cross examining Arias this week, Martinez has spent hours going back and forth with the defendant over word choice, her memory, and her answers to his questions.

"Everyone who takes witness stand for defense is an enemy," McDonald said. "He prides himself on being able to work by rarely referring to his notes, but what he's giving up in that is that there's so much time he wastes on stupid comments. A lot of what I've heard is utterly objectionable."

Martinez's behavior has spurred frequent objections of "witness badgering" from Arias' attorney Kirk Nurmi, who at one point Tuesday stood up in court and appealed to the judge to have a conference with all of the attorneys before questioning continued. Judge Sherry Stephens at one point admonished Martinez and Arias for speaking over one another.

Andy Hill, a former spokesperson for the Phoenix police department, and Steven Pitt, a forensic psychiatrist who has testified as an expert witness at many trials in the Phoenix area, both said that despite his aggressive style, Martinez would likely succeed in obtaining a guilty verdict.

"When it comes to cross examination, one size does not fit all," said Pitt. "But if you set aside the incessant sparring, what the prosecutor I believe is effectively doing is pointing out the various inconsistencies in the defendant's version of events."

We need a piece of Mars to continue search for life

THERE'S no need to cry over spilt chemicals. Thanks to an accident inside one of its instruments, NASA's Curiosity rover has detected the presence of a substance called perchlorate in Martian soil (see "Curiosity's spills add thrills to the Mars life hunt").

Not exactly earth-shattering, you might think. But it adds a new twist to the most controversial chapter in Martian history: did the Viking landers detect life?

This is a question that has divided the Viking missions' researchers for almost three decades. One group has resolutely stuck to its guns that the landers detected signs of life. Equally adamant is a second group who say they absolutely did not – a view that has always been the official version of events.

The unexpected discovery of perchlorate supplies a legitimate reason to reopen the debate. Perchlorate is an oxidising agent that destroys organic molecules. Its presence could finally explain the disputed results.

The episode highlights another important issue. Curiosity is a sophisticated machine, but there is only so much soil chemistry we can do from millions of kilometres away. A sample return mission must be a priority.
