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.

Tennis: Li shocks Sharapova to reach Australian Open final

MELBOURNE: China's Li Na stormed into the final of the Australian Open with a straight-sets win over Maria Sharapova, leaving her one victory away from her second major title.

Li, 30, defeated the world number two 6-2, 6-2 in 1hr 33min and will now meet the winner of Thursday's second semi-final between world number one Victoria Azarenka and American teenager Sloane Stephens.

"Every time I'm back in Australia, I always feel something here," said Li, the 2011 runner-up. "I always play well here. Everyone can be nervous in a final, so I have to enjoy it. I'm looking forward to the final."

Sharapova had lost only nine games in her march to the semi-finals, a tournament record, but Li was always going to provide a far sterner test despite trailing 4-8 in their head-to-head.

And the Russian started disastrously with consecutive double faults as she was broken in the opening game.

Four-time major-winner Sharapova could have returned to world number one if she had won her second Australian Open title, but Li's ball-striking had her on the back foot from the beginning.

Benefiting from her intense off-season fitness training under new coach Carlos Rodriguez, Li was untroubled by sweltering heat in Melbourne and broke for a second time to take a 4-1 lead.

Her serving was steady, and her ground strokes were probing. Two close video rulings went against Li, and Sharapova retrieved one of the service breaks, only to hand it straight back. China's 2011 French Open champion closed out the opening set in 48 minutes.

Li, 30, missed a sitter of a forehand in a worrying sign at the beginning of the second set.

She held strong on her serve, however, and Sharapova stumbled in the fifth game. The fifth of Sharapova's six double faults handed Li another chance to break and when the Russian went long with a backhand, Li led 3-2.

She led 40-15 in the next game but Sharapova unloaded some ferocious winners to reach break point. Li recovered to move within sight of the finish line, breaking again for 5-2.

Li lost her first match point by hooking wide a forehand, but she then polished off the upset victory as Sharapova finished with a ruinous 32 unforced errors.

NYPD unveils radiation scanner to catch people with illegal guns

As the U.S. gun control debate continues in full force, several authorities are looking for ways to catch people illegally possessing firearms.

The New York Police Department announced today that it will soon adopt portable scanning technology that lets police officers see from a distance whether someone is carrying a concealed weapon, according to the New York Daily News.

The scanner is a device small enough to fit in a police van or set up on a street corner that reads terahertz radiation, which is energy emitted by both humans and inanimate objects. When aimed at a person, it's possible to see anything that is blocking the specific energy coming off the human -- such as a gun.

"If something is obstructing the flow of that radiation, for example a weapon, the device will highlight that object," Police Commissioner Raymond Kelly said, according to the New York Daily News.

Using terahertz machines has been the subject of controversy among civil liberties groups. Not only can authorities "search" individuals without cause, but false positives can also lead to unjustified stops.

The NYPD said it hopes to start testing the device in high-crime areas in the near future, according to the New York Daily News.

"We still have a number of trials to run before we can determine how best to deploy this technology," Kelly said. "We're also talking to our legal staff about this. But we're very pleased with the progress we've made over the past year."

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.

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, though the services will have until January 2016 to complete the implementation of the changes.

"We certainly want to see this executed responsibly but in a reasonable time frame, so I would hope that this doesn't get dragged out," said former Marine Capt. Zoe Bedell, who joined a recent lawsuit aimed at getting women on the battlefield.

The military services also will have until January 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.

"The reality of the battlefield has changed really since the Vietnam era to where it is today," said Rep. Tammy Duckworth, D-Ill., a former military helicopter pilot who lost both her legs in combat. "Those distinctions on what is combat and what is not really are falling aside. So I think that after having seen women, men, folks who -- cooks, clerks, truck drivers -- serve in combat conditions, the reality is women are already in combat."

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.

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.

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.

South Korea welcomes new UN sanctions on North

SEOUL: South Korea on Wednesday welcomed fresh UN Security Council sanctions on North Korea and warned Pyongyang against ignoring demands to scrap its nuclear weapons and ballistic missile programmes.

The 15-nation council meeting in New York unanimously adopted Tuesday a resolution that "condemned" North Korea's rocket launch last month and threatened "significant action" if it stages a new nuclear test.

North Korea's space agency, a bank, four trading companies and four individuals were added to an existing UN sanctions list for an assets freeze and travel ban.

In a statement, South Korea's Foreign Ministry backed the resolution, saying it reflected the international community's "shared concern" over the North's December 12 rocket launch.

"North Korea must... fully abide by the UN Security Council resolution by scrapping all nuclear weapons and related programmes, and halting all activities associated with ballistic missile launches," it said.

"It also must pay attention to the fact that the UN Security Council has said it would take significant action if it commits further provocative acts," the statement added.

Last month, a US think-tank, citing satellite photos, said the North had repaired extensive rain damage at its nuclear test site in the northeast of the country and could conduct a detonation at two weeks' notice.

North Korea insists that last month's rocket launch was a peaceful, scientific mission aimed at putting a satellite in space.

The UN resolution condemned it as a disguised ballistic missile test that violated existing sanctions imposed after the North's nuclear tests in 2006 and 2009.

North and South Korea are still technically at war because their 1950-53 conflict ended in a truce, not a treaty,

LTE users to hit 1 billion by 2016

The rise in worldwide subscribers on 4G LTE has far exceeded expectations. In just three years since its nascent beginnings, the mobile technology has skyrocketed -- going from 600,000 users in 2010 to nearly 100 million subscribers in 2012.

Now, in a new report, market research firm IHS iSuppli is projecting that global users will double in 2013 and by 2016 LTE will claim more than 1 billion subscribers.

"With LTE emerging as a true global technology standard, its ecosystem now faces both challenges and opportunities," iSuppli's senior analyst for wireless communications Wayne Lam said in a statement. "Rapid adoption will drive design innovations, particularly in smartphones, but issues like spectrum fragmentation will also remain an overhang for the LTE industry that requires attention. Overall, however, the LTE space will be less worried about rifts or divisions in technology, and more concerned with laying the foundation for sustained growth across the entire LTE landscape."

In 2010, analysts projected that LTE would reach 300 million users by 2015. But at the rate wireless technology is now proliferating, iSuppli believes it could reach this many people by 2014. Just in the last year LTE subscribers jumped 599 percent from 13.2 million subscribers in 2011 to 92.3 million in 2012. It's projected that LTE users will reach 198.1 million by the end of 2013.

As smartphone technology and apps become increasingly more comprehensive and dependent on faster delivery, wireless infrastructure has to keep up. This has proven difficult in some aspects, according to iSuppli. For example, while 3G registered on just a few spectrums, LTE has registered more than 40 different frequency spectrums so far. So, even though subscribers are multiplying, kinks still need to be ironed out.

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.
