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.

Is it a bird? A plane? No, just a guy named Oscar

BUENOS AIRES: He was a self-styled superhero, prowling the gritty outskirts of Buenos Aires wearing a mask and cartoonish outfit and armed only with a flashlight, compass and pepper spray as he took on bad guys.

But now his cover is blown, thanks to an alleged shootout with muggers, and the superhero is charged with carrying an unlicensed gun, police said Wednesday.

The man who called himself Menganno -- Spanish for Joe Blow -- and became famous in Argentine media is actually one Oscar Lefosse, 43, a former cop who served from 1986 to 1996. It turns out his gun license expired a year ago.

On Monday, Lefosse told police that three petty criminals opened fire on his car as he drove with his wife. He returned fire with his Glock pistol.

On his Facebook page, "Menganno" -- 33,000 followers -- posted a photo of what he said was his bullet ridden car.

But a policeman quoted by the news agency Telam said the shots all came from inside the car.

"He could have killed somebody, an innocent bystander. He is irresponsible," the official said.

In an interview with AFP in 2010, Menganno described himself as "a real, flesh and blood superhero. My goal is for all of us to be better and show more solidarity. Injustice makes me sick."

He said then that he only defended himself with a flashlight, pepper spray and a compass, and had a company in the security sector. He did not elaborate.

"I do not walk around the street armed. I keep my gun at home," he said Wednesday on Argentine TV.

Lefosse used to hide his identity behind a mask that was a mix of dark and baby blue and coordinated nicely colour-wise with a Superman style suit he wore, with a symbol on his chest to boot.

Sundance )

The Steve Jobs biopic starring Ashton Kutcher will open in theaters on April 19, the movie's distributor announced today.

The indie film, which is set to debut Friday at the Sundance Film Festival in Park City, Utah, on Firday, covers Jobs' life during the years 1971 through 2000 -- a time frame that includes the founding of Apple, as well as his ouster, the forming of NeXT and Pixar, and then his return to the company when Apple acquired NeXT.

The movie should not to be confused with a separate production penned by "The Social Network" and "The West Wing" writer Aaron Sorkin. That movie is said to be based on Walter Isaacson's biography, while "jOBS" is based on widely available information.

Principal photography on "jOBS" began at Jobs' childhood home in Los Altos, Calif., in June. Photos from the production have since leaked out, showing Kutcher and others in costume.

Along with Kutcher, the movie also stars Matthew Modine as former Apple CEO John Sculley, Josh Gad as Apple co-founder Steve Wozniak, and "The Help" star Ahna O'Reilly playing Chris-Ann Brennan, Jobs' girlfriend, and the mother of his daughter Lisa. Other additions include J.K. Simmons and Kevin Dunn, who will play venture capitalist Arthur Rock and former Apple CEO Gil Amelio respectively.

Deformed Dolphin Accepted Into New Family

In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic news).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

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.

Google's Native Client reaches ARM-based Chromebooks

Google has finished a version of its Native Client programming technology that extends beyond mainstream x86 PC processors into the world of ARM chips.

Native Client, or NaCl for short, is designed to let programmers easily adapt the C or C++ software they've written for native software so that it can run as a part of Web apps, too. It's designed for high performance, but it's also got security mechanisms built in to counter the risks of running malicious code directly on the processor. The first version of NaCl, though, only worked on personal computers using Intel or AMD's x86 chips.

Google's David Sehr announced NaCl for ARM today with version 25 of its NaCl software developer kit, which programmers use to build NaCl programs.

The technology is designed so that programmers can bring their existing code to the Web -- for example, game designers who have written a physics engine in C++. But NaCl has been at odds with the Web philosophy in one important way, namely, that NaCl software doesn't simply run on any device with a browser.

Extending to ARM is thus an important for NaCl, because ARM chips power almost every smartphone out there. But this version of NaCl doesn't do that -- it only works on the new ARM-based Samsung Chromebooks.

To reach mobile phones, Google is banking on a revamp called Portable Native Client, or PNaCl. It adopts a low-level translation technology called LLVM that adapts native code to a variety of processors.

"With Portable Native Client, we'll be able to support not just today's architectures, but also those of tomorrow - and developers won't have to recompile their app," Sehr said in the blog post.

With PNaCl, programmers will be able to produce a single package (with the .pexe extension rather than NaCl's .nexe extension) that will run on all supported devices. With today's approach, programmers must produce separate .nexe files for ARM and for x86.

Another major challenge for Native Client is attracting support. It's built into Chrome, but no other major browser maker supports it, and Mozilla is downright frosty about NaCl.

So far you can only get NaCl software through Google's Chrome Web Store. That's also a big departure from the ordinary Web, where you simply point a browser at a Web page to fetch the necessary HTML, CSS, and JavaScript software.

That'll change with PNaCl, too, Google said. The Chrome Web Store is required today to ensure software is compatible with different chip architectures, Google said in a statement. PNaCl sheds this chip-architecture constraint.

The Promise and Perils of Mining Asteroids

Encouraged by new space technologies, a growing fleet of commercial rockets and the vast potential to generate riches, a group of entrepreneurs announced Tuesday that they planned to mine the thousands of near-Earth asteroids in the coming decades.

The new company, Deep Space Industries (DSI), is not the first in the field, nor is it the most well-financed. But with their ambition to become the first asteroid prospectors, and ultimately miners and manufacturers, they are aggressively going after what Mark Sonter, a member of DSI's board of directors, called "the main resource opportunity of the 21st century." (Related: "Asteroid Hunter to Be First Private Deep-Space Mission?")

Prospecting using miniaturized "cubesat" probes the size of a laptop will begin by 2015, company executives announced. They plan to return collections of asteroid samples to Earth not long after.

"Using low cost technologies, and combining the legacy of [the United States'] space program with the innovation of today's young high tech geniuses, we will do things that would have been impossible just a few years ago," said Rick Tumlinson, company chairman and a longtime visionary and organizer in the world of commercial space [not sure what commercial space means].

"We sit in a sea of resources so infinite they're impossible to describe," Tumlinson said.

Added Value

There are some 9,000 asteroids described as "near-Earth," and they contain several classes of resources that entrepreneurs are now eyeing as economically valuable.

Elements such as gold and platinum can be found on some asteroids. But water, silicon, nickel, and iron are the elements expected to become central to a space "economy" should it ever develop.

Water can be "mined" for its hydrogen (a fuel) and oxygen (needed for humans in space), while silicon can be used for solar power systems, and the ubiquitous nickel and iron for potential space manufacturing. (See an interactive on asteroid mining.)

Sonter, an Australian mining consultant and asteroid specialist, said that 700 to 800 near-Earth asteroids are easier to reach and land on than the moon.

DSI's prospecting spacecraft will be called "FireFlies," a reference to the popular science fiction television series of the same name. The FireFlies will hitchhike on rockets carrying up communication satellites or scientific instruments, but they will be designed so that they also have their own propulsion systems. The larger mining spacecraft to follow have been named "DragonFlies."

Efficiencies

It all sounds like science fiction, but CEO David Gump said that the technology is evolving so quickly that a space economy can soon become a reality. Providing resources from beyond Earth to power spacecraft and keep space travelers alive is the logical way to go.

That's because the most expensive and resource-intensive aspect of space travel is pushing through the Earth's atmosphere. Some 90 percent of the weight lifted by a rocket sending a capsule to Mars is fuel. Speaking during a press conference at the Santa Monica Museum of Flying in California, Gump said that Mars exploration would be much cheaper, and more efficient, if some of the fuel could be picked up en route. (Related: "7 Ways You Could Blast Off by 2023.")

Although there is little competition in the asteroid mining field so far, DSI has some large hurdles ahead of it. The first company to announce plans for asteroid mining was Planetary Resources, Inc. in spring 2012—the group is backed by big-name investors such as Google's Larry Page and Eric Schmidt, filmmaker James Cameron, and early Google investor Ram Shriram. DSI is still looking for funding.

Owning Asteroids

While these potential space entrepreneurs are confident they can physically lay claim to resources beyond Earth, there remain untested legal issues.

The United Nations Space Treaty of 1967 expressly forbids ownership of other celestial bodies by governments on Earth. But American administrations have long argued that the same is not true of private companies and potential mining rights.

While an American court has ruled that an individual cannot own an asteroid—as in the case of Gregory Nemitz, who laid claim to 433 Eros as a NASA spacecraft was approaching it in 2001—the question of extraction rights has not been tested.

Moon rocks brought back to Earth during the Apollo program are considered to belong to the United States, and the Russian space agency has sold some moon samples it has returned to Earth-sales seen by some as setting a precedent.

Despite the potential for future legal issues, DSI's Gump said his group recently met with top NASA officials to discuss issues regarding technology and capital, and came away optimistic. "There's a great hunger for the idea of getting space missions done with smaller, cheaper 'cubesat' technology and for increased private sector involvement."

Everyone involved acknowledged the vast challenges and risks ahead, but they see an equally vast potential—both financial and societal.

"Over the decades, we believe these efforts will help expand the civilization of Earth into the cosmos, and change what it means to be a citizen of this planet," Tumlinson said.

Al Qaeda Commander Killed for the 3rd Time

The second in command of al Qaeda's Yemen affiliate was reportedly killed in an airstrike in Yemen in December, according to a news report by Arabic television network Al Arabiya, the third time the former Guantanamo detainee has been reported dead since 2010.

According to the report, Said al-Shihri died last month after sustaining severe injuries from a joint U.S.-Yemeni airstrike that targeted a convoy in which he was riding. The al Arabiya account, based on information from "family sources," said that the airstrike left al-Shihri in a coma. He allegedly died soon after and was buried in Yemen.

On Tuesday afternoon, hours after the initial report, a Yemeni government official denied having any information regarding the death of al-Shihri, according to Arabic news site al-Bawaba.

No photos of a body have yet surfaced and no mention of his death has appeared on jihadi forums.
This is the third time al-Shihri, the second in command of al Qaeda in the Arabian Peninsula (AQAP), has been reported killed since 2009. In 2010, the Yemeni government claimed it had captured him. In September 2012, Yemeni news sites reported he was killed in an American drone strike.

Al-Shihri, a "veteran jihadist," traveled to Afghanistan shortly after the Sept. 11, 2001 terror attacks to fight coalition troops, only to be captured weeks later, according to West Point's Combating Terrorism Center. He was sent to the U.S. prison in Guantanamo Bay, Cuba, where he stayed for six years before being released to Saudi Arabia. There, he entered a so-called "jihadi rehab" program that attempted to turn terrorists into art students by getting them to get "negative energy out on paper," as the program's director told ABC News in 2009.

But just months after he supposedly entered the fingerpainting camp, al-Shihri reappeared in Yemen where he was suspected to have been behind a deadly bombing at the U.S. embassy there.

At the time, critics of the "jihadi rehab" program used al-Shihri as evidence that extremists would just go through the motions in order to be freed.
