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.

Taiwanese activists head for Japan-controlled isles

TOKYO: A boatload of Taiwanese activists protected by the island's coastguard was on Thursday heading for Japanese-held islands at the centre of a bitter international wrangle involving Tokyo, Beijing and Taipei.

The seven activists left port in Taiwan on a fishing vessel in the early hours and were expected to arrive in the area around the uninhabited islands about noon (0400 GMT), Taiwanese coastguard spokesman Shih Yi-che said.

A coastguard official in Japan said the vessel was "sailing towards the Senkakus".

The islands in the East China Sea, whose seabed is believed to harbour valuable mineral reserves, are known as Senkaku in Japanese and Diaoyu in Chinese. Both China and Taiwan claim them.

The group said it was on its way to plant a statue of a sea goddess believed by coastal communities in the region to have the power to protect seafarers, but it was not clear if the activists would attempt to land.

It also intended to "maintain sovereignty" against Japan's control, said Hsieh Mang-lin, the Taiwanese chairman of the Chinese Association for Protecting the Diaoyutais (Diaoyu Islands), in a short statement.

Japanese broadcaster NHK reported that Taipei had dispatched six patrol boats to "monitor" the ship, adding it was the same one that had entered waters off the islands in July.

Taiwan's coastguard denied it was an organised flotilla.

"Coastguard ships that patrol the area routinely will protect the boat," said spokesman Shih, who declined to give the number of official Taiwanese vessels in the area.

"The coastguard will protect our people's voluntary actions to defend the Diaoyu islands. Coastguard vessels will go wherever the fishing boat is... to defend our sovereignty and protect our fishing rights," a statement said.

In September, coastguard vessels from Japan and Taiwan duelled with water cannon after dozens of Taiwanese boats were escorted by patrol ships into the islands' waters.

Earlier, Japanese media reports had said there were Hong Kong activists on board the boat, but a spokesman for the southern Chinese territory's main Diaoyu protest group told AFP it was not involved.

Previous activist landings have resulted in the arrest and deportation of those setting foot on what Japan says has been its indisputable territory for more than a century.

The rocky island outposts have been the scene of a diplomatic tussle between Japan and China for months.

Japan's government nationalised three of them in September by taking them out of private Japanese ownership.

Since then, Beijing has repeatedly sent government ships into the waters. In December, a Chinese government plane flew over them, leading Japan to scramble fighter jets.

Earlier this month, both militaries had jets in the area and Japanese newspapers have reported that Tokyo is mulling allowing its pilots to fire warning shots.

While most commentators believe Asia's two largest economies will find some way to work around the problem, which has rattled relations for decades, some are warning that a mis-step could lead to armed confrontation.

Prosecutor: Disabled victims held 'like zoo animals'

STORY HIGHLIGHTS

• Five indicted in alleged fraud, abuse scheme


• Indictment alleges hate crimes


• Two victims died


• Alleged ringleader could face death penalty

Philadelphia (CNN) -- Four adults imprisoned in a dark Philadelphia boiler room, beaten and underfed, were confined like zoo animals, federal prosecutors said Wednesday in announcing a 196-count indictment against their alleged captors.

The litany of federal charges against the alleged ringleader and her posse is the first hate crime case of its kind -- the victims were mentally and physically disabled, the U.S. Attorney's Office said.

Charges against the five defendants, together and individually, include sex trafficking, murder, fraud and forced human labor, among others.

The defendants, according to prosecutors, held the four victims in subhuman conditions in a scheme to steal Social Security disability payments.

Linda Ann Weston, 52, was described by police as the ringleader of an alleged fraud and abuse scheme.

Linda Ann Weston, 52, whom police have described as the ringleader, her daughter, Jean McIntosh, 33, Gregory Thomas, Sr., 49, Eddie Wright, 52, and Nicklaus Woodard, 26, are accused of using isolation, intimidation, threats of violence and violence to control the victims and each defendant had a role in the racketeering enterprise, according to the indictment.

Brother of basement captive describes emotional reunion

The investigation into Weston and her alleged co-conspirators began when the four adults were found in October 2011 locked in the sub-basement room with no food and only a bucket for a toilet.

According to the indictment, the defendants beat the victims, kept them captive in locked closets, basements and attics, deprived them of adequate food and medical care, and moved them between Pennsylvania, Texas, Virginia, and Florida in order to further the scheme and evade law enforcement.

The defendants also are charged with violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act -- which criminalizes violence motivated by any person's actual or perceived disability, race, color, national origin, religion, sexual orientation, gender, or gender identity -- for their alleged actions against the disabled victims.

"The physically and mentally disabled are among the most vulnerable in our society. They deserve to be treated with respect and compassion, not violence," U.S Attorney Zane David Memeger said in a statement. "Linda Weston and others, in fact, decided to prey on these victims specifically because of their physical and mental challenges and they did so through violence, fear and intimidation for the purpose of stealing Social Security payments that were meant for the victims' long-term care."

As the first hate crimes case of its kind because the victims were disabled, the indictment alleges that Weston's "abusive control and confinement techniques" caused the deaths of two of the victims, including Weston's former roommate, Maxine Lee, who she allegedly continued to collect benefits from after she died of acute meningitis.

The medical examiner said a contributing factor in Lee's death was "cachexia of unknown origin," or malnutrition. The manner of death is listed as "natural causes."

New details emerge in case of people held captive in Philadelphia

"Shocking does not begin to describe the criminal allegations in this case where the victims were tied up and confined like zoo animals and treated like property akin to slaves," Memeger said.

The four adults held captive -- Edwin Sanabria, Herbert Knowles, Tamara Breeden and Derwin McLemire -- were locked in a pitch-black, 13-by-7 foot room that housed the former boiler used to heat the building, police said.

A penetrating stench of urine and feces still hung in the chamber days after the discovery. McLemire had been chained to the boiler, police said.

"I used the bucket to go to the bathroom. Others used the same bucket," Sanabria testified last January at hearing where a judge ordered the case to go to trial. When asked where he took a bath, he said they "used the same bucket we used to urinate in."

Lawyer: Police contacted in 2003 about chief suspect

The investigation took several bizarre twists as authorities tried to piece together the evidence in the case, which has spread to at least two other states after detectives discovered that one of the accused had traveled across state lines with the people found in the boiler room.

"Today's Indictment represents just one more step towards closure and healing, not only for the victims of this heinous hate crime, but for the community as a whole," FBI Special Agent-in-Charge John Brosnan said in a statement.

If convicted of all federal charges, each of the defendants faces a statutory maximum sentence of life in prison. Weston potentially faces the death penalty and mandatory restitution of approximately $212,000.

Due to the federal charges, the state plans to withdraw its charges against Weston, Thomas, Wright and McIntosh, according to the district attorney's office in Philadelphia. They were scheduled to go on trial January 28.

Weston's attorney was not immediately available for comment.

Women now equal men in lung cancer deaths

U.S. women who smoke today have a much greater risk of dying from lung cancer than they did decades ago, partly because they are starting younger and smoking more - that is, they are lighting up like men, new research shows.

Men who smoke have long had higher lung cancer death rates, but now women have caught up in their risk of dying from smoking-related illnesses. Lung cancer risk leveled off in the 1980s for men but is still rising for women, the study found.

New cancer screening guides for heavy smokers

"It's a massive failure in prevention," said one study leader, Dr. Michael Thun of the American Cancer Society. And it's likely to repeat itself in places like China and Indonesia where smoking is growing, he said. About 1.3 billion people worldwide smoke.

The research is in Thursday's New England Journal of Medicine. It is one of the most comprehensive looks ever at long-term trends in the effects of smoking and includes the first generation of U.S. women who started early in life and continued for decades, long enough for health effects to show up.

The U.S. has more than 35 million smokers - about 20 percent of men and 18 percent of women. The percentage of people who smoke is far lower than it used to be; rates peaked around 1960 in men and two decades later in women.

In 2009, 205,974 people in the United States were diagnosed with lung cancer, including 110,190 men and 95,784 women, according to the Centers for Disease Control and Prevention. That same year, 87,694 men and 70,387 women passed away from the disease.

Researchers wanted to know if smoking is still as deadly as it was in the 1980s, given that cigarettes have changed (less tar), many smokers have quit, and treatments for many smoking-related diseases have improved.

They also wanted to know more about smoking and women. The famous surgeon general's report in 1964 said smoking could cause lung cancer in men, but evidence was lacking in women at the time since relatively few of them had smoked long enough.

One study, led by Dr. Prabhat Jha of the Center for Global Health Research in Toronto, looked at about 217,000 Americans in federal health surveys between 1997 and 2004.

A second study, led by Thun, tracked smoking-related deaths through three periods - 1959-65, 1982-88 and 2000-10 - using seven large population health surveys covering more than 2.2 million people.

Among the findings:

- The risk of dying of lung cancer was more than 25 times higher for female smokers in recent years than for women who never smoked. In the 1960s, it was only three times higher. One reason: After World War II, women started taking up the habit at a younger age and began smoking more.

-A person who never smoked was about twice as likely as a current smoker to live to age 80. For women, the chances of surviving that long were 70 percent for those who never smoked and 38 percent for smokers. In men, the numbers were 61 percent and 26 percent.

-Smokers in the U.S. are three times more likely to die between ages 25 and 79 than non-smokers are. About 60 percent of those deaths are attributable to smoking.

-Women are far less likely to quit smoking than men are. Among people 65 to 69, the ratio of former to current smokers is 4-to-1 for men and 2-to-1 for women.

-Smoking shaves more than 10 years off the average life span, but quitting at any age buys time. Quitting by age 40 avoids nearly all the excess risk of death from smoking. Men and women who quit when they were 25 to 34 years old gained 10 years; stopping at ages 35 to 44 gained 9 years; at ages 45 to 54, six years; at ages 55 to 64, four years.

-The risk of dying from other lung diseases such as emphysema and chronic bronchitis is rising in men and women, and the rise in men is a surprise because their lung cancer risk leveled off in 1980s.

Shocking ads: Tips from smokers

Changes in cigarettes since the 1960s are a "plausible explanation" for the rise in non-cancer lung deaths, researchers write. Most smokers switched to cigarettes that were lower in tar and nicotine as measured by tests with machines, "but smokers inhaled more deeply to get the nicotine they were used to," Thun said. Deeper inhalation is consistent with the kind of lung damage seen in the illnesses that are rising, he said.

Scientists have made scant progress against lung cancer compared with other forms of the disease, and it remains the leading cause of cancer deaths worldwide. More than 160,000 people die of it in the U.S. each year.

The federal government, the Canadian Institutes of Health Research, the Bill and Melinda Gates Foundation, the cancer society and several universities paid for the new studies. Thun testified against tobacco companies in class-action lawsuits challenging the supposed benefits of cigarettes with reduced tar and nicotine, but he donated his payment to the cancer society.

Smoking needs more attention as a health hazard, Dr. Steven A. Schroeder of the University of California, San Francisco, wrote in a commentary in the journal.

"More women die of lung cancer than of breast cancer. But there is no `race for the cure' for lung cancer, no brown ribbon" or high-profile advocacy groups for lung cancer, he wrote.

Kathy DeJoseph, 62, of suburban Atlanta, finally quit smoking after 40 years - to qualify for lung cancer surgery last year.

"I tried everything that came along, I just never could do it," even while having chemotherapy, she said.

It's a powerful addiction, she said: "I still every day have to resist wanting to go buy a pack."

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.

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.

US urges Bangladesh to hold free, fair trials

WASHINGTON: The United States urged Bangladesh to hold free and fair trials after a war crimes court sentenced a fugitive TV preacher to death Monday amid allegations the tribunal is politically motivated.

The International Crimes Tribunal, a domestic body with no international oversight, ordered Maolana Abul Kalam Azad to be hanged for genocide and murder during the bloody 1971 liberation war against Pakistan.

"The United States supports bringing to justice those who commit such crimes," State Department spokeswoman Victoria Nuland said in a statement.

"However, we believe that any such trials must be free, fair and transparent, and in accordance with domestic standards and international standards Bangladesh has agreed to uphold through its ratification of international agreements."

Azad, who for years presented a widely watched show on Islam on private and state-run television channels, is a former leading light of Bangladesh's largest opposition Islamic party Jamaat-e-Islami.

The 63-year-old TV host has been on the run for about a year.

In total, 11 top opposition figures -- nine from Jamaat and two from the main opposition Bangladesh Nationalist Party (BNP) -- stand accused of war crimes.

Both Jamaat and the BNP have called the cases "politically motivated and farcical" and international rights groups have questioned the proceedings and found loopholes in the war crime laws.

The Bangladeshi government says the trials are fair and meet international standards.

"The United States urges the government of Bangladesh to adhere to the due process standards that are part of its treaty obligations, and to fully respect the rule of law" as it addresses atrocities committed during the liberation war, Nuland said.

Evidence shows bold L.A. priest abuse cover-up

(CBS News) LOS ANGELES - There is new evidence that leaders of the Catholic Church in Los Angeles maneuvered secretly to shield priests accused of sexually abusing children.

Documents just released indicate they never told parishioners -- or the police -- what they knew.

"What we're seeing in these files is but a glimpse into a very, very dark, and endless tunnel of secrecy, of abuse, of silence," said Raymond Boucher, a former altar boy and current lead attorney, representing some 500 victims of sex abuse by priests in the archdiocese of Los Angeles.

Ten years after revelations of massive sex abuse cover-ups, many victims never get their day in court

The documents offer the strongest evidence yet of a cover-up that reached to the very top of Los Angeles clergy: Then-archbishop, now-retired Cardinal Roger Mahony.

"That has always been paramount for the church for decades: Protect itself from scandal," Boucher said.

Many of the documents are correspondence between Mahony and Monsignor Thomas Curry, his chief adviser on sex abuse. One concerns whether to allow Monsignor Peter Garcia to return to his duties in L.A. He had secretly been sent away for treatment in New Mexico for sexually abusing as many as 17 youngsters.

No one in the church hierarchy alerted authorities.

Mahony wrote on July 22, 1986: "I believe if Monsignor Garcia were to reappear here within the archdiocese we might very well have some type of legal action filed in both the criminal and civil sectors. Signed, sincerely yours in Christ, most reverend Roger Mahony."

Monsignor Curry concurred: "There are numerous - maybe 20 - adolescents or young adults that Peter Garcia was involved with in a first degree felony manner. The possibility of one of these seeing him is simply too great."

Cardinal Mahony issued this statement Tuesday to the victims: "I pray for them every single day."

It ends simply: "I'm sorry."

Victims held a press conference Tuesday. Manny Vega says was abused from age 10 to 15.

"Conscious, clear decisions were made to hide these priests and move them around and never, never did they consider the well-being of the children that they destroyed and left behind," Vega said.

Monsignor Garcia has passed away, and Monsignor Curry did not respond to requests for comment from CBS News.

As many as 30,000 more documents from the archdiocese sex abuse settlement are to be released in the coming weeks.

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.
