Wallace: Wonders of nature have been solace of my life

Alfred Russel Wallace discovered natural selection independently of Charles Darwin. Through his letters, available online for the first time, he tells us of his research, expeditions and enduring fascination for nature's mysteries.

You are famously joint author, with Darwin, of the first paper describing the origin of species and natural selection, published in 1858. When did you first get the idea?
I begin [in 1847] to feel rather dissatisfied with a mere local collection – little is to be learnt by it. I sh[ould]d like to take some one family, to study thoroughly – principally with a view to the theory of the origin of species. By that means I am strongly of [the] opinion that some definite results might be arrived at.

This desire led you to Brazil to collect birds, butterflies and beetles to try to discover what drives the evolution of new species. Were there any incidents on the voyage?
On Friday the 6th of August [1852]… the Captain (who was the owner of the vessel) came into the cabin & said "I am afraid the ship's on fire. Come & see what you think of it."

Despite that harrowing experience, you next undertook an 8 year expedition to the Malay Archipelago, where you discovered the invisible boundary between the animals of Asia and the Australian region, which would later be called the Wallace Line in your honour. What fascinated you most on that trip?
The Birds have however interested me much more than the insects, they are proportionally much more numerous, and throw great light on the laws of Geographical distribution of Animals in the East… As an instance I may mention the Cockatoos, a group of birds confined to Australia & the Moluccas, but quite unknown in Java Borneo Sumatra & Malacca… Many other species illustrate the same fact.

You have been famously good-natured about sharing the discovery of natural selection with Darwin…
I also look upon it as a most fortunate circumstance that I had a short time ago commenced a correspondence with Mr. Darwin on the subject of "Varieties", since it has led to the earlier publication of a portion of his researches & has secured to him a claim to priority which an independent publication either by myself or some other party might have injuriously effected

What did you and Darwin have in common?
In early life both Darwin and myself became ardent beetle-hunters. Both Darwin and myself had, what he terms "the mere passion of collecting"… Now it is this superficial and almost child-like interest in the outward forms of living things, which, though often despised as unscientific, happened to be the only one which would lead us towards a solution of the problem of species.

Do you feel your contribution has been overlooked?
The idea came to me, as it had come to Darwin, in a sudden flash of insight: it was thought out in a few hours – was written down with such a sketch of its various applications and developments… then copied on thin letter-paper and sent off to Darwin – all within one week.

I should have had no cause for complaint if the respective shares of Darwin and myself in regard to the elucidation of nature's method of organic development had been thenceforth estimated as being, roughly, proportional to the time we had each bestowed upon it when it was thus first given to the world – that is to say, as 20 years is to one week.

You helped Darwin with the puzzle of bright colouration in animals, which led to the concept of warning colours. To ask his question again, why are some caterpillars so brightly coloured?
[Since some]… are protected by a disagreeable taste or odour, it would be a positive advantage to them never to be mistaken for any of the palatable caterpillars… Any gaudy & conspicuous colour therefore, that would plainly distinguish them from the brown & green eatable caterpillars, would enable birds to recognise them easily as a kind not fit for food, & thus they would escape seizure which is as bad as being eaten.

How did you feel looking back on your life's work, at the age of 89?
The wonders of nature have been the delight and solace of… life. Nature has afforded… an ever increasing rapture, and the attempt to solve some of her myriad problems an ever-growing sense of mystery and awe.

Do you have a message for our readers?
I sincerely wish you all some of the delight in the mere contemplation of nature's mysteries and beauties which I have enjoyed.

'Avatar' director Cameron accused over screenplay

LOS ANGELES: A US judge ordered director James Cameron to hand over drafts of the screenplay for "Avatar" Wednesday, to lawyers for a man claiming he wrote the script on which the 3D blockbuster was based.

Eric Ryder is seeking compensation from Cameron and his production company Lightstorm Entertainment, claiming that the 2009 Oscar-nominated film is based on a story he wrote called "K.R.Z. 2068."

He filed a lawsuit in December 2011, saying he spent two years developing the story. On Wednesday Los Angeles Superior Court Judge Alan Rosenfield ordered Cameron's lawyers to turn over screenplay drafts.

"We have to be careful and sensitive about ideas and information," said the judge.

But he denied a request by Ryder's lawyers to grant access to the personal calendars of Cameron and Jon Landau, the chief operating officer of Cameron's Lightstorm Entertainment Inc.

Ryder's lawyer K. Andrew Kent said his legal team will also get access to backup tapes from computers used by Cameron.

"Avatar," about a paraplegic US marine with split loyalties after being sent to a distant world wanted for its mining potential, was seen as a breakthrough in the use of 3D technology, and has grossed more than US$2.7 billion worldwide.

'Dell dude': I can save Dell, dude

He was a wonder in his day.

(Credit:
TelevisionArchives/YouTube Screenshot by Chris Matyszczyk/CNET)

I already know what you're thinking. I'm like that sometimes.

You're thinking: "What is he, high?"

You're thinking that because Ben Curtis, he who once used to invade your home through your TV and say, "You're getting a Dell, dude," believes he can make a comeback and resurrect the brand.

You're also thinking that because Curtis was once arrested for trying to buy marijuana in New York.

On the other hand, it's clear that Dell isn't in quite the shape that it used to be, and vultures -- I mean, admirers -- are circling to lend a hand.

Perhaps this is why it took just one e-mail from Bloomberg to Curtis in order to learn of his master plan.

"I think they're making a huge mistake and simply need to bring back the Dell Dude!," he wrote. "That's it. That's all they need to do. If they brought me back, their sales, stock and media presence would skyrocket. That is by FAR the smartest move they could make."

More Technically Incorrect

Curtis knows smart. When he was ludicrously arrested in the pot bust, he did happen to be wearing a kilt.

It would be fair, too, to ask what the word "Dell" has conjured in people's minds since the company chose to release Curtis because of that arrest.

In my mind, the name is associated most strongly with "The Rich Kids of Instagram" and Padma Lakshmi's baby.

Why wouldn't a return of the Dude, deftly conceived, at least create a little renewed affection for the brand?

Perhaps it could start with him living in Colorado, creating a brand-new (and very legal) pot-growing business and running the whole thing on Dell machinery.

In successive episodes, he rises in the business world, all the time making the Dell product more aspirational. One day, he is asked to become CEO of Dell.

The tagline? "Dell Will Get You Higher," of course.

10 Ways Obama Could Fight Climate Change

One of the biggest surprises of President Barack Obama's inaugural address on Monday was how much he focused on fighting climate change, spending more time on that issue than any other.

"We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," Obama said.

The President pointed out that recent severe weather supplied an urgent impetus for energy innovation and staked the nation's economic future on responding to a changing climate.

"We cannot cede to other nations the technology that will power new jobs and new industries—we must claim its promise," Obama said. "That's how we will maintain our economic vitality and our national treasure—our forests and waterways; our croplands and snowcapped peaks. That is how we will preserve our planet, commanded to our care by God."

So what could the President reasonably do to deliver on that vow? National Geographic asked experts in climate research, energy innovation, and oceanography. Here are ten of their suggestions:

1. Sunset coal with new incentives and regulations. "Provide incentives to phase out the oldest, most polluting power plants," said Robert Jackson, a climate scientist at Duke University. It's already happening, to some degree, as more of the nation transitions to natural gas. Earth scientist Bill Chameides, dean of Duke's Nicholas School of the Environment and a former chief scientist at the Environmental Defense Fund, urges the administration to use its Clean Air Act authority to promulgate carbon regulations for existing power plants like it has for new ones: "Doing that will force fuel switching from coal to natural gas." (Related: "6 Ways Climate Change Will Affect You.")

2. Invest federal stimulus money in nuclear power. It's hardly a perfect fuel, as accidents like Japan's Fukushima fallout have shown, but with safety precautions new nuclear plants can meaningfully offset dirtier types of energy, supporters say. "Nuclear is the only short- to medium-term way to really get away from fossil fuels," said Peter Raven, president emeritus of the Missouri Botanical Garden. He said the damage done by relentless global warming will far exceed the damage done by faults in the nuclear system.

3. Kill the Keystone pipeline. The controversial Keystone XL oil pipeline is up for review again by the White House this year. "The first thing he should do to set the tone to a lower carbon economy is to reject the Keystone pipeline," said Raymond Pierrehumbert, a geophysical scientist at the University of Chicago. The pipeline was never going to be a major driver of global emissions, but Pierrehumbert and some other environmentalists say that by killing it the President would send a clear message about America's intent to ramp down fossil fuels. (See pictures of the animals that helped kill the Keystone pipeline.)

4. Protect the oceans by executive order. Land use is complicated, but large swaths of oceans can be protected by executive fiat. Just as President George W. Bush designated the world's largest marine monument northwest of Hawaii in 2006, Obama could single-handedly protect other areas. National Geographic Explorer-in-Residence Sylvia Earle said the President should focus on parts of the Arctic that are under U.S. control, putting them off limits to energy production, commercial fishing, and mineral exploration. Marine sanctuaries won't stop climate change, but they can give marine species a better chance of adapting to it by reducing the other man-made threats the animals face. (Read about the many benefits of marine reserves.)

5. Experiment with capturing carbon. Huge untapped reserves of natural gas and oil make it unlikely that the U.S. will transition away from fossil fuels in the immediate future. Instead, said Wallace Broecker, geology professor at Columbia University's Lamont-Doherty Earth Observatory, we should attack the atmosphere's carbon surplus directly. "[Obama] could make available funds to build and test prototype air capture units" to capture and store CO2, said Broecker. Removing some carbon from the atmosphere could buy valuable time as policy makers and scientists explore more permanent solutions.

6. Grow government research for new energy sources. The Department of Energy has a nimble program that's tasked with innovative energy research—the Advanced Research Projects Agency-Energy. The ARPA-E funds research in biofuels, transmission, and battery storage, with an annual budget of $275 million. Last year, DOE officials requested at least $75 million more. Increasing funding for ARPA-E, said Rafe Pomerance, former deputy assistant secretary of state for environment and development and currently an environmental consultant, "you get new technologies that undercut coal, oil, and gas." Plus, he said, you get a competitive advantage if American researchers uncover the next big idea in new energy.

7. Tax carbon. Congress would have to agree, but many climate experts say that the most meaningful way to tackle emissions is to set a price on carbon. "We should be asking people to pay the cost of putting carbon into the atmosphere as they buy the fuel," said Josh Willis, climate scientist and oceanographer at NASA's Jet Propulsion Laboratory. To gain political support for the idea, Obama would probably have to show that the tax would help accelerate technology, grow new industries, and pay down the deficit.

8. Dial back the federal government's energy use. With more than 1.8 million employees, $500 billion in annual purchasing power, and 500,000 buildings to operate, the federal government has been a leader in reducing energy use since Obama signed a 2009 executive order to cut waste. "I would urge him to keep using the power of government to promote energy conservation," said Syndonia Bret-Harte, an Arctic biologist who studies climate change at the University of Alaska, Fairbanks.

9. Build a scientific clearinghouse for climate information. "I advocate for building a better information system on what is happening and why," said Kevin Trenberth, head of the Climate Analysis Section at the U.S. National Center for Atmospheric Research. That involves compiling observations related to climate change from around the world and using the data to refine climate modeling. Think of it as a one-stop, user-friendly website that clearly demonstrates how weather data from around the globe are influenced by broader shifts in the planet's climate.

10. Keep talking. Despite a consensus among top scientists, the world still needs some convincing on climate change. A CNN poll last week found that just 49 percent of Americans agree that global warming is real and is due to human activities. "The most important thing the President can do is to build on his inaugural comments to heighten the sense of urgency about rapid climate destabilization and clarify its connection to virtually every other issue on the national agenda," said David Orr, environmental studies professor at Oberlin College. That means using the bully pulpit to show how a more volatile climate affects everything from agriculture to transportation to 21st-century warfare.

Christine Dell'Amore, Rob Kunzig, and Jane J. Lee contributed reporting.

Pentagon to Allow Women in Combat

Defense Secretary Leon Panetta will lift a longstanding ban on women serving in combat, according to senior defense officials.

The services have until this May to come up with a plan to implement the change, according to a Defense Department official.

That means the changes could come into effect as early as May. The services will have until January 2016 to complete the implementation of the changes.

The military services will also have until Janurary 2016 to seek waivers for certain jobs -- but those waivers will require a personal approval from the secretary of defense and will have to be based on rationales other than the direct combat exclusion rule.

The move to allow women in combat, first reported by the Associated Press, was not expected this week, although there has been a concerted effort by the Obama administration to further open up the armed forces to women.

The Joint Chiefs of Staff unanimously recommended in January to Secretary Panetta that the direct combat exclusion rule should be lifted.

"I can confirm media reports that the secretary and the chairman are expected to announce the lifting of the direct combat exclusion rule for women in the military," said a senior Defense Department official. "This policy change will initiate a process whereby the services will develop plans to implement this decision, which was made by the secretary of defense upon the recommendation of the Joint Chiefs of Staff."

Chairman of the Joint Chiefs Gen. Martin Dempsey sent Panetta a memo earlier this month entitled, "Women in Service Implementation Plan."

"The time has come to rescind the direct combat exclusion rule for women and to eliminate all unnecessary gender-based barriers to service," the memo read.

"To implement these initiatives successfully and without sacrificing our warfighting capability or the trust of the American people, we will need time to get it right," he said in the memo, referring to the 2016 horizon.

Women have been officially prohibited from serving in combat since a 1994 rule that barred them from serving in ground combat units. That does not mean they have been immune from danger or from combat.

As Martha Raddatz reported in 2009, women have served in support positions on and off the frontlines in Iraq and Afghanistan, where war is waged on street corners and in markets, putting them at equal risk. Hundreds of thousands of women deployed with the military to those two war zones over the past decade. Hundreds have died.

Woman have been able to fly combat sorties since 1993. In 2010, the Navy allowed them on submarines. But lifting restrictions on service in frontline ground combat units will break a key barrier in the military.

READ MORE: Female Fighter Pilot Breaks Gender Barriers

Panetta's decision will set a January 2016 deadline for the military service branches to argue that there are military roles that should remain closed to women.

In February 2012 the Defense Department opened up 14,500 positions to women that had previously been limited to men and lifted a rule that prohibited women from living with combat units.

Panetta also directed the services to examine ways to open more combat roles to women.

However, the ban on direct combat positions has remained in place.

Advocates for equality in the services will be pleased. On Capitol Hill today, retired Chief Master Sgt. Cindy McNally, a victim of sexual assault in the military, said placing women in combat roles would help equalize the services and actually cut down on sexual assaults, which have emerged as a major problem in the military.

MIT website hacked in tribute to Aaron Swartz

Hal Hodson, technology reporter

A tribute to internet activist Aaron Swartz replaced the homepage for the Massachusetts Institute of Technology today, in an apparent act of protest over the university's role in the legal case that led up to Swartz's suicide on 11 Jan.

For a short time, visitors to the MIT.edu home page found a message that read: "R.I.P. Aaron Swartz. Hacked by grand wizard of Lulzsec, Sabu. God Bless America. Down With Anonymous." The background was watermarked with words from a blog post, written by Swartz, titled "Immoral".

Attributing the defacement to "grand wizard of Lulzsec, Sabu" lent the page a sarcastic air, as it's widely known that the former Lulzsec leader was outed as an FBI informant last year.

The attack on MIT's website came amid widespread criticism of how the university handled the case against Swartz, including an article in The New York Times that quoted Swartz's father as saying: "We don't believe [MIT] acted in a neutral way. My belief is they put their institutional concerns first."

According to MIT's service status page, network service was restored within the university as of 1:30 pm EST. The university had not yet returned New Scientist's request for comment when this story was published.

This is the second time since Swartz' death that the MIT site has been the target of attacks. Previously, an MIT sub-domain was replaced with a manifesto for reform of computer and copyright laws. The authors claimed to be operating as a part of the online activist group, Anonymous.

Marines beat a retreat in Beyonce lip-sync flap

WASHINGTON: The US Marine Corps beat a hasty retreat Tuesday from a furore over whether Beyonce lip-synched "The Star-Spangled Banner" at President Barack Obama's public inauguration ceremony.

First, the New York Times quoted a US Marine Band spokeswoman as saying that, just before Beyonce took the stage Monday, the musicians learned a version of the national anthem it had pre-recorded with her would be used.

"We don't know why," said the spokeswoman, Master Sergeant Kristin duBois. "But that is what we were instructed to do... It's not because Beyonce can't sing. We all know Beyonce can sing. We all know the Marine Band can play."

But later, the Marine Corps said only that a pre-recorded version of the band's musical track was played to the crowd outside the Capitol after Obama was sworn into office for a second term.

Since the band did not have a chance to rehearse with Beyonce beforehand, "it was determined that a live performance by the band was ill-advised for such a high-profile event," it said.

But as for Beyonce's vocal performance, it added: "No one in the Marine Band is in a position to assess whether it was live or pre-recorded."

Beyonce's publicist did not respond to emails Tuesday, leaving it unclear as to whether or not the R&B diva had pulled off the biggest karaoke number in the history of US presidential inaugurations, or somehow just mimed the words.

Also unexplained was a black-and-white Instagram photo, supposedly taken Sunday, of Beyonce in a wool beret and cardigan in a recording studio with three soldiers behind her. She appeared to be listening intently to something.

Equally mysterious was why Beyonce removed the ear monitor mid-way through the song. Singers performing over an instrumental track might do so if the playback is clashing with what's coming out of the loudspeakers.

One way or another, fans of Beyonce -- who sang "The Star-Spangled Banner" live at last year's Super Bowl and returns to the American football classic in February as its half-time act -- rallied behind her on Twitter.

"Who cares that Beyonce Lip #Sync the National Anthem, it was recorded live an hour before. You try singing in that cold," tweeted one fan, referring to Monday's near-freezing temperatures in Washington.

"Beyonce certainly acted like a diva ... but I don't see how that can be compared to Lance Armstrong cheating for 7 straight years at the least," said another Twitter user, referring to the disgraced cyclist.

"Beyonce is the best lip-syncer I've seen," added a third fan. "Because she surely fooled me."

The US Marine Band is the premier musical ensemble of the US Marine Corps. It's also known as the President's Own for its longstanding connection with the White House and important national events.

It played live for most of Monday's inauguration on the Capitol steps, but prior to any major event, it routinely goes into the studio to record its repertoire as a precautionary measure.

"Each piece of music scheduled for performance in the Inauguration is pre-recorded for use in case of freezing temperatures, equipment failure or extenuating circumstances," the Marine Corps statement said.

Pop star Kelly Clarkson and folk singer James Taylor also performed at the inauguration.

Senator disputes Aaron Swartz's SOPA, Protect IP role

Peter Eckersley, the Electronic Frontier Foundation's technology projects director and Aaron Swartz's former roommate, speaks at a gathering in San Francisco.

Declan McCullagh/CNET)

Patrick Leahy, chairman of the Senate Judiciary committee, is taking issue with a description of how a discussion with one of his aides led the late Aaron Swartz to campaign against Hollywood-backed copyright bills.

At an event in San Francisco last weekend, Peter Eckersley, Swartz's former roommate and the Electronic Frontier Foundation's technology projects director, told an audience that the late activist created the advocacy group Demand Progress after a fruitless meeting with one of Leahy's aides.

Aaron Cooper, who works for Leahy -- the author of the Protect IP Act -- as the chief intellectual property counsel for the Senate Judiciary committee, told Swartz during the meeting that "the priority of this country is going to be making sure that files cannot be shared, songs cannot be copied, movies cannot be copied," Eckersley said.

Jessica Brady, a spokeswoman for Senate Judiciary Committee, told CNET this afternoon that's absolutely not what happened:

T

he third-party description of the November 2010 conversation between Aaron Cooper and Aaron Swartz is entirely fabricated. It is wrong on the substance, and it is wrong on the very nature of their conversation. The two had a positive meeting, and their discussion focused mainly on whether an agreement could be reached to go after infringers and counterfeiters living in countries where the United States does not have extradition treaties. Aaron Cooper -- a tireless, highly respected and superbly knowledgeable policy advisor on these and other complex issues -- never said anything remotely similar to the quote described in this false account. Further, the timeline provided in this account is inaccurate. The organization Demand Progress began well before the two men met in late November of 2010. And finally, the support Senator Leahy received for his version of the legislation from the Internet service provider community, as well as domain name registries and registrars, is evidence that ensuring the legislation would not 'break' the Internet was a top priority for Senator Leahy and his staff.

Domain name registrar GoDaddy initially supported, but after a customer boycott, backed down and said it opposed the Stop Online Piracy Act and Leahy's similar Protect IP Act. AT&T said at the time that "we have been supportive of the general framework" of Protect IP, which stopped short of a formal endorsement, and Verizon expressed concerns about SOPA.

Swartz committed suicide on January 11 in New York City. His family and friends have blamed Carmen Ortiz, 57, the U.S. attorney for Massachusetts, for filing 13 felony charges against the late activist for allegedly downloading academic journals he was permitted to access (but not access in large quantities). A congressional investigation of Ortiz, who has denied any wrongdoing, is underway.

Eckersley -- who did not immediately respond to a request for comment -- told the story about Swartz at a retrospective event titled "a year after SOPA/PIPA," organized by EFF, Engine Advocacy, and Craig Newmark's craigconnects. SOPA was, of course, the Stop Online Piracy Act; PIPA was Leahy's Senate counterpart also known as the Protect IP Act.

Space Pictures This Week: Solar Tantrum, Petroglyphs at Night

Photograph by Tony Rowell, Your Shot

This image of Native American petroglyphs, or rock art, shot against the Milky Way, was taken in California's eastern Sierra Nevada on January 14.

Petroglyphs—one of many forms of rock art—are created by scraping, rubbing, or chiseling designs into the patina coating desert rocks. Depending on the conditions surrounding a piece of rock art, these designs can endure for hundreds to thousands of years. (Watch a video about Arizona's rock art.)

Erosion and natural processes, such as plant growth, can fade or destroy the designs. They can also fall victim to vandalism and theft.

According to news reports, one of the most recent incidences was discovered in late October 2012. Unknown perpetrators hacked six petroglyphs out of the cliff face at the Eastern Sierra Volcanic Tableland near Bishop, California (map). They damaged others using saws and hammers.

Left Turn? Obama Speech Invigorates Progressives

A presidential campaign that was largely about jobs and the economy gave way during Monday's inaugural ceremonies to a sweeping affirmation of progressivism and call for "collective action."

Now, liberal allies of President Obama say they're closely watching to see whether the second-term president follows through on issues with which he has struggled before.

Obama's groundbreaking references to climate change and gay rights in his second inaugural address particularly surprised many progressive interest groups, which said their first-term frustrations have been replaced by a new sense of optimism.

"We are hopeful that the president's progressive speech signals a major strategy shift for the Obama administration," said Adam Green, co-founder of the Progressive Change Campaign Committee.

Green's group and other liberal Democrats have openly expressed disappointment in Obama since 2009, saying his agenda has fallen short. Many have cited his failure to advance an assault-weapons ban, as promised, enact climate change legislation or overhaul the nation's immigration system.

Other progressives have chafed at Obama's extension of the Bush-era tax cuts for the wealthy in 2010 and move last month to make some of the cuts permanent, while putting changes to Social Security and Medicare on the table as part of a deficit-reduction deal.

During the election campaign, Obama ran no paid TV advertising that mentioned gays or gay rights, or the term "climate change," for example. Only four of his ads mentioned environmental issues, and two explicitly portrayed Obama as a defender of the coal industry, something anathema to many environmentalists.

"If the president's inaugural words and action on guns are the template for his governing strategy in a second term, that will allow the president to win big victories and secure a legacy of bold progressive change," Green said, responding to Obama's inaugural address.

In interviews with ABC News, advocates stressed that success on many liberal priorities remains a big "if," with a politically divided Congress and a record of failure by the White House to bridge the divide.

On the environment, activists say they are most closely watching the president's upcoming decision on the proposed Keystone XL Pipeline project, which would carry oil from the tar sands of Alberta to the U.S. Gulf Coast.

Obama delayed a decision on the project in January 2012, ordering a new environmental-impact study. But with that study nearing completion, he will be forced to weigh in on an issue that has pitted a need for jobs and cheaper energy with environmental and health concerns.

"The decision on the Keystone XL pipeline will be the first indicator about how seriously he's taking climate change over the next four years," said Erich Pica, president of Friends of the Earth, an environmental advocacy group opposed to the pipeline. "We'll know in the next month and a half to two months whether he does."

Bill McKibben, an author and leading environmentalist, said in a blog post that he is not holding his breath. "With words like that, it's easy to let ourselves dream that something major might be about to happen to fix the biggest problem the world has ever faced," he wrote.
"And given the record of the last four years, we know that too often rhetoric has yielded little in the way of results."

McKibben is organizing a major environmental rally in Washington on Feb. 17.
