Smartphones make identifying endangered animals easy

Everyday mobile tech takes the legwork out of tracking hard-to-find animals, and makes life easier for field biologists

FIELD biology is notoriously laborious. In one famous 1982 study, Smithsonian entomologist Terry Erwin counted by hand the number of insect species in one hectare of forest canopy in Panama. By extrapolation Erwin estimated the total biodiversity of Earth's insects. What if your smartphone could take some of the strain?

Harvard biologist and computer scientist Walter Scheirer has devised a machine vision system that automatically recognises and counts specific animals and runs on a Motorola Droid X2 smartphone. This will help biologists make quicker, more accurate judgements about the health of delicate ecosystems.

Two years ago, Edwards Air Force Base in the Mojave desert, California, put out a call for a cheap way to monitor the animals that live there. The area is one of the last refuges for the endangered desert tortoises as well as the threatened Mojave ground squirrels (see map). Keeping an eye on the health of the animal population in such a remote location is time-consuming and expensive. So Scheirer developed detection and classification algorithms capable of identifying tortoises and squirrels with nothing more than a standard smartphone.

Automated camera traps already exist, but they are not selective enough. "Right now, we have to manually go through every photo to identify species and separate photos of interest from false photos. It's a very laborious task," says Princeton conservation biologist Siva Sundaresan, who works with Grévy's zebras in Kenya. He says Scheirer's method is potentially very useful to biologists.

But how does a phone tell the difference between a squirrel and a rock or a tumbleweed? Scheirer's system starts off by scanning its environment for objects that could be the animals it wants. It looks for clumps of pixels that are new to the scene, then examines them to decide whether they represent any of the animals it has been trained to recognise. Rather than checking each individual pixel, Scheirer's algorithms analyse the content of a frame of video and look for patterns of pixels that identify the animal. The algorithms don't need intensive processing and so run well on smartphones.

A paper due to be presented at the Workshop on the Applications of Computer Vision in Clearwater, Florida, later this month shows how well the algorithms work, with the system able to distinguish between three different species of ground squirrel 78 per cent of the time, even though they are almost identical. Scheirer says that the algorithms have been tweaked and that the recognition rate is now around 85 per cent.

Scheirer says his goal is to build a cheap, easy-to-use system that can automatically detect animals in any environment. More field trials are scheduled for next month, and the team aims to deliver a finished system to the US Air Force by 2014.

Princeton population biologist Dan Rubenstein says machine vision systems will also help us understand delicate ecosystems in finer detail. "You won't be generalising from such small scale to such a massive scale," he says. "We're going to be able to save ecosystems."

Another system presented at the conference, called Hotspotter, recognises individual animals like zebras and giraffes by their stripes and spots, although it still needs some human guidance, unlike the Mojave desert system. Rubenstein, who works on Hotspotter, says that systems like this will allow biologists to look at animals and their actions on an individual basis. "We could start to build massive databases of who's who, and how they move in time. We can use social networks to figure out how they relate to each other."

Taiwan probes illegal money transfer for Macau casinos

TAIPEI: Taiwanese prosecutors said on Thursday they were investigating a locally-based Hong Kong firm for allegedly carrying out huge money transfers for use in Macau casinos, circumventing strict forex rules.

The company, which opened in Taiwan in 2009, allegedly accepted deposits by Taiwanese gamblers allowing them to withdraw the money once they were in Macau, said the Taipei district prosecutors' office.

Prosecutors, who declined to identify the firm, said they suspected it was behind a total of US$179 million in illegal transactions.

The head of the company was questioned on Wednesday on suspicion of violating Taiwanese law which stipulates only banks are allowed to handle domestic and international money transfers, it said in a statement.

Taiwanese media said the services are popular among some gamblers due to Taiwanese laws restricting the amount of cash travellers can take with them abroad to US$10,000 per person.

The company reportedly also offered cash advances to entertainers, elected officials, business tycoons and leading gangsters to help promote business for the Macau casinos.

As there currently is no legal casino in Taiwan, many of the island's gamblers have turned to Macau, which is little more than an hour away by airplane.

The offshore Taiwanese island of Penghu last year passed a referendum to open the first legal casino in Taiwan, although it is still pending a separate law by the parliament on regulating gambling establishments.

Latino should have played lead in 'Argo'

Ben Affleck plays the lead role of Tony Mendez in "Argo," which he also directed.

STORY HIGHLIGHTS

• Oscar nominations on Thursday, and Ben Affleck expected to get one for "Argo"


• Affleck plays real-life Latino who helped diplomats escape in Iran hostage crisis


• Ruben Navarrette: Affleck should have used a Latino actor to play role


• He says it cheats actor out of a job, and the Latino community out of a hero's story

San Diego, California (CNN) -- The upcoming Oscars are no stranger to causes or controversy. And this year, there is a strong dose of both surrounding the film "Argo" -- and its star and director, Ben Affleck.

This controversy bubbled up when the buzz started that Affleck could get an Academy Award nomination for best director when the announcements are made Thursday.

"Argo" tells how an ingenious and daring CIA agent helped orchestrate the rescue of six U.S. diplomats from Tehran during the Iran hostage crisis of 1979-1980. In November 1979, about 300 Islamic students stormed the U.S. Embassy and 66 Americans were taken hostage. But six U.S. diplomats escaped and were hidden at the Canadian Embassy by the Canadian ambassador and his wife.

Ruben Navarrette Jr.

The CIA agent -- Antonio "Tony" Mendez, played by Affleck -- successfully led the mission to evacuate the Americans, which involved Mendez and his associates posing as a Canadian film crew that was eager to make a movie in Iran.

The real Tony Mendez was awarded the Intelligence Star for Valor, and other honors, for leading the rescue. He later wrote a memoir, detailing the events in Tehran.

"Argo" is loosely based on Mendez's book. Better make that, very loosely based. As movie critics and others have pointed out since the movie opened a few months ago, the filmmakers took lots of dramatic license with the story. Mendez's role is played up, while that of the Canadians who helped hide and protect the Americans is played down. Some scenes depicted in the film never happened. Some characters are composites of several real people.

In other words, it's what you would expect from a Hollywood feature film based on a historical event. It's not a documentary. It's meant to be taken with a grain of salt, and to be entertaining.

Still, there are some Latinos -- in and out of Hollywood -- who think that, in this case, the filmmakers, and especially Affleck, pushed the concept of creativity too far. They say Affleck missed an opportunity to put more Latinos on screen. Moreover, they say, Affleck improperly claimed, for himself, the choice role of Mendez when he should have cast a Latino actor instead. They insist that the director didn't just cheat a Latino out of an acting job but the Latino community out of a feel-good story about one of their own who won acclaim for a heroic deed.

The critics are right, and their cause is just. Affleck should have tried to cast a Latino to play Mendez. That's common sense, and it would have made "Argo" a better movie. Affleck also didn't do himself any favors by trying to dismiss the criticism with a glib remark that essentially said that it really doesn't matter that the actor playing Mendez isn't Latino since Mendez himself isn't, shall we say, overtly Latino.

At a recent forum intended to publicize the film, Affleck responded to a question from the audience about the controversy by noting that "Tony does not have, I don't know what you would say, a Latin/Spanish accent" and that "You wouldn't necessarily select him out of a line of 10 people and go 'This guy's Latino.' "

Ouch. At least Affleck didn't slip and say "line up."

"So I didn't feel as though I was violating something," he said, "where, here's this guy who's clearly ethnic in some way and it's sort of being whitewashed by Ben Affleck the actor."

Johnny Depp set a better example. Several months ago, Depp turned down the role of Mexican revolutionary Francisco "Pancho" Villa in another film. He said that the role should go to a Latino. I praised Depp at the time for showing that, besides being a great actor, he is also a person of character.

The exclusion of Latinos from Hollywood is an old story. This is still a black and white world, where Latinos rarely get cast in the leading role. We're the gardeners and housekeepers, the gang leader and drug dealers, the nannies and farm workers. That's it. There has been some progress, of course. But not enough -- not when you have a Latina in the Supreme Court, three Latinos in the U.S. Senate, and Latinos heading Fortune 500 companies.

I could blame the environment of Southern California, in which most Hollywood writers, producers and directors live and spend most of their time. When they get up in the morning and drive to work, most Latinos they encounter are subservient. We clean their homes, cook their breakfast, trim their hedges, park their cars and otherwise help them get through the day.

Still, you can push this argument too far, and wind up going down a dangerous path -- one that ultimately sets back the greater cause of trying to get television networks and film studios to create a broader range of meatier roles for Latino actors and actresses.

After all, it's a short walk from saying that a director should have cast a Latino to play a Latino to arguing that only Latinos can play Latinos. And, if that's the argument, then on what moral high ground do Latinos stand to also push -- as we should -- for Latino actors and actresses to be considered for generic and mainstream roles that could have gone to white actors? We can't have it both ways.

Even if Latinos succeed in making their point about this one director and this one movie, it could backfire. We could win this battle, and still lose the war.

But before Latinos can be fully integrated into America and not considered outsiders, we have to take every opportunity to push for inclusion and fairness. And acknowledging that Latinos have the skills to play themselves is a good start.

New rules seek to shield consumers, mortgage lenders

WASHINGTON Federal regulators for the first time are laying out rules designed to ensure that mortgage borrowers can afford to repay the loans they take out.

The rules being unveiled Thursday by the Consumer Financial Protection Bureau impose a range of obligations and restrictions on lenders, including bans on the risky "interest-only" and "no documentation" loans that helped inflate the housing bubble.

Lenders will be required to verify and inspect borrowers' financial records. They generally will be prohibited from saddling borrowers with loan payments totaling 43 percent of the person's annual income.

CFPB Director Richard Cordray, in remarks prepared for an event Thursday, called the rules "the true essence of 'responsible lending."'

The rules, which take effect next year, aim to "make sure that people who work hard to buy their own home can be assured of not only greater consumer protections but also reasonable access to credit," he said.

Cordray noted that, in years leading up to the 2008 financial crisis, consumers could easily obtain mortgages that they could not afford to repay. In contrast, in subsequent years, banks tightened lending so much that few could qualify for a home loan.

The new rules seek out a middle ground by protecting consumers from bad loans while giving banks the legal assurances they need to increase lending, he said.

The mortgage-lending overhaul is a priority for the agency, which was created under the 2010 financial law known as the Dodd-Frank Act. The agency is charged with reducing the risk of a credit bubble by helping to ensure that borrowers are better informed and loans are more likely to be repaid.

The agency is charged with writing and enforcing rules that flesh out the law passed by Congress. Some provisions are required under the law, but the agency had broad discretion in designing many of the new requirements.

The rules limit features like teaser rates that adjust upwards and large "balloon payments" that must be made at the end of the loan period.

They include several exceptions aimed at ensuring a smooth phase-in and protecting access to credit for underserved groups. For example, the strict cap on how much debt consumers may take on will not apply immediately. Loans that meet separate federal standards also would be permitted for the first seven years.

Balloon payments would be allowed for certain small lenders that operate in rural or underserved communities, because other loans may not be available in those areas.

The bureau also proposed amendments that would exempt from the rules some loans made by community banks, credit unions and nonprofit lenders that work with low- and moderate-income consumers.

Holmes 'Delighted' by Creepy Self-Portraits: Victims

After two days of apparent indifference, accused Aurora shooter James Holmessmiled and smirked at disturbing self-portraits and images of weapons shown in court today, according to the families of victims who watched him.

"When he sees himself, he gets very excited and his eyes crinkle," Caren Teves said outside of the courthouse, after the hearing. "Your eyes are the window to the soul and you could see that he was very delighted in seeing himself in that manner."

Teves' son Alex Teves, 24, died in the shooting.

Prosecutors showed photos that Holmes took of himself hours before he allegedly carried out a massacre at a Colorado movie theater. He took a series of menacing self-portraits with his dyed orange hair curling out of from under a black skull cap and his eyes covered with black contacts. In some of the photos, guns were visible.

Those haunting photographs, found on his iPhone, were shown in court today on the last day of a preliminary testimony that will lead to a decision on whether the case will go to trial. The hearing concluded without Holmes' defense calling any witnesses.

The judge's decision on whether the case will proceed to trial is expected on Friday.

Holmes, 25, is accused of opening fire on a crowded movie theater in Aurora, Colo., on July 20, 2012, killing 12 people and wounding dozens others during a showing of "Dark Knight Rises."

The court room's set-up kept members of the media from being able to see Holmes' face as the photos were displayed, but victims and their families could watch him.

Teves said that Holmes was "absolutely smirking" when images of his weapons and the iPhone photos he took of himself were shown in court.

"I watched him intently," Caren Teves' husband Tom Teves said. "I watched him smile every time a weapon was discussed, every time they talked about his apartment and how he had it set up (with booby traps), and he could have gave a darn about the people, to be quite frank. But he's not crazy one bit. He's very, very cold. He's very, very calculated."

Holmes' has exhibited bizarre behavior after the shooting and while in custody. His defense team has said that he is mentally ill, but have not said if he will plead insanity.

"He has a brain set that no one here can understand and we want to call him crazy because we want to make that feel better in our society, but we have to accept the fact that there are evil people in our society that enjoy killing any type of living thing," a frustrated Tom Teves said. "That doesn't make them crazy. And don't pretend he's crazy. He's not crazy."

The photos presented in court showed Holmes mugging for his iPhone camera just hours before the shooting.

Half-a-dozen photos showed Holmes with his clownish red-orange hair and black contact lenses giving the photos a particularly disturbing edge.

In one particularly odd image, he was making a scowling face with his tongue out. He was whistling in another photo. Holmes is smiling in his black contacts and flaming hair in yet another with the muzzle of one of his Glock pistols in the forefront.

Yet another photo showed him dressed in black tactical gear, posing with an AR-15 rifle.

Time to nail the number one problem of green energy

ONE of the frustrating things about renewable energy is that there is so much of it available and yet we utilise so little. Every minute, enough solar radiation hits the earth to meet global energy needs for a year. Wind energy, too, could single-handedly power the planet.

Why don't we harvest this bounty and end our dangerous reliance on coal, oil and gas? One of the main reasons is the storage problem. Whereas fossil fuels conveniently package up chemical energy for release on demand, wind and solar only generate electricity at the whim of the weather.

What's needed is a way to store surplus wind and solar energy. That much has been obvious for years, but there are signs that the problem is finally reaching its rightful place - at the very top of the renewables agenda. Technologies are advancing, particularly liquid-air storage (see "Saving renewable energy with air"). Investment is pouring in. And outdated regulations that have acted as a drag are being swept away. Anyone who tells you that renewable energy will never be reliable enough to replace fossil fuels is increasingly telling yesterday's story.

Third Delhi gang-rape suspect to plead not guilty: lawyer

NEW DELHI: A third suspect accused of fatally gang-raping a 23-year-old student in a moving bus in New Delhi last month will plead not guilty to all charges, his lawyer said on Wednesday.

Advocate M L Sharma said he would file the plea on behalf of Ram Singh, the driver of the bus where the attack allegedly took place which has fuelled angry protests across India.

"I am representing Ram Singh and I will file a 'not guilty' plea," Sharma, who is also representing Singh's brother Mukesh and labourer Akshay Thakur in the case, told AFP.

The advocate said on Tuesday that the other two men would also plead not guilty to the string of charges including gang-rape, murder and kidnapping.

"Whoever committed this heinous crime should be punished but my clients are not the real culprits," he said.

It is not yet clear who will represent the two remaining defendants. All five men are residents of New Delhi slums aged from 19 to 35. A sixth accused, who is 17, is to be tried in a separate court for juveniles.

Officials at Tihar jail, the maximum security prison where the accused are held, confirmed that Sharma had met Ram Singh late on Tuesday.

Prosecutors have said they have evidence of bloodstains linking the men to the attack, but the advocate said he would challenge the police over their handling of evidence, while refusing to give details.

The next hearing, to be held behind closed doors, has been scheduled for Thursday when a magistrate is expected to transfer the case for trial in a special fast-track court.

The brutal attack on the medical student and her boyfriend has stirred anger in India, with politicians and the murder victim's family calling for the death penalty for the culprits.

The pair had been to watch a film when they were lured onto a bus. The gang are accused of repeatedly raping and violating the woman with an iron bar, causing horrific internal injuries.

National Cathedral to wed same-sex couples

By Ben Brumfield, CNN

updated 2:37 AM EST, Wed January 9, 2013

STORY HIGHLIGHTS

• Same-sex couples have lined up to marry in city halls


• Washington National Cathedral is the site of presidential funerals


• Four presidents have had inaugural prayers there


• It is also a place of worship for the Episcopal Church

(CNN) -- When laws went into effect in three states for same-sex couples to marry, many were quick to line up at their city halls to exchange vows. Now they may do so in one of the nation's most prominent churches -- the Washington National Cathedral.

Most Americans know the house of God, also called the Cathedral Church of St. Peter and St. Paul, as a place where sacred rites are carried out on behalf of the nation. It has been host to the funerals of numerous presidents and of inaugural prayer services for four presidents, including Barack Obama.

But it is also an active house of worship in the Episcopalian Church, said the Cathedral's dean, Gary Hall. The denomination has developed a blessing rite that mirrors current wedding ceremonies for heterosexual couples and allows each bishop to decide to allow same-sex marriages in their churches or not.

Bishop Mariann Budde decided to allow the rite, since same-sex marriage is legal in the District of Columbia and now in neighboring Maryland as well, Hall said.

Same-sex marriage amendments in U.S.

HIDE CAPTION

It was Budde's decision that led Hall to create the same-sex rite.

He sees it as "another historic step toward greater equality."

The states of Washington, Maine and Maryland all legalized same-sex marriages in referendums during the 2012 general election. It was already legal in the nation's capital.

In March, the Supreme Court will hear oral arguments in two appeals cases related to same-sex marriage -- California's Proposition 8, which bans same-sex marriage and the federal Defense of Marriage Act, which denies federal benefits to same-sex couples.

The American Episcopal Church is intimately connected with the Church of England, which last week approved the advancement of male priests in same-sex committed relationships to the position of bishop. But those relationships must be celibate.

City halls in Baltimore; Portland, Maine; and Seattle erupted in celebration as the first same-sex couples tied the knot in December and January. Seattle's ceremony included 133 couples, who walked outside and down rain-slickened steps afterward, where they were greeted by cheers, confetti and a brass band celebrating the first day same-sex couples could marry in Washington.

To wed at the National Cathedral, one member of the couple must be baptized into the Church, and both must commit to a Christian marriage of "lifelong faithfulness, love, forbearance and mutual comfort."

N.Y.'s Cuomo pushing for much tougher gun law

A deal that would give New York one of the toughest gun control laws in the nation was being sought by Gov. Andrew Cuomo who, sources told CBS New York station WCBS-TV, was hoping to announce the plan Wednesday during his State of the State address.

The sources said Cuomo was negotiating furiously with legislative leaders in an attempt to reach a deal before the address.

The measures would be a response to gun violence in the U.S., including the tragic shooting at Sandy Hook Elementary School in Newtown, Conn., in which 26 children and adults were killed.

Sources said the package was expected to include new restrictions on assault weapons, stiffer penalties for using a gun to commit a crime, and new limits on the number of bullets in a gun magazine.

Cuomo's move comes as New York City Mayor Michael Bloomberg's Mayors Against Gun Violence released a new commercial to push for federal action.

It features Roxanna Green, the mother of Christina Taylor-Green, who was killed two years ago Tuesday in the Tucson, Ariz., massacre in which former Rep. Gabby Giffords was wounded.

"How many more children must die before Washington does something to end our gun violence problem?" Roxanna Green asks in the ad.

It would be quite a coup for Cuomo, a potential 2016 presidential candidate, to show progress on gun control as Washington stays divided on the controversial topic.

Late Tuesday night, a Cuomo spokesman said the sides still had not reached an agreement, but sources said there was talk of keeping the legislature in session the rest of the week to make sure a deal gets done.

Dead Lotto Winner's Wife Seeks 'Truth'

The wife of a $1 million Chicago lottery winner who died of cyanide poisoning told ABC News that she was shocked to learn the true cause of his death and is cooperating with an ongoing homicide investigation.

"I want the truth to come out in the investigation, the sooner the better," said Shabana Ansari, 32, the wife of Urooj Khan, 46. "Who could be that person who hurt him?

"It has been incredibly hard time," she added. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone."

Ansari, Khan's second wife, told the Chicago Sun-Times that she prepared what would be her husband's last meal the night before Khan died unexpectedly on July 20. It was a traditional beef-curry dinner attended by the married couple and their family, including Khan's 17-year-old daughter from a prior marriage, Jasmeen, and Ansari's father. Not feeling well, Khan retired early, Ansari told the paper, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She called 911.

Khan, an immigrant from India who owned three dry-cleaning businesses in Chicago, won $1 million in a scratch-off Illinois Lottery game in June and said he planned to use the money to pay off his bills and mortgage, and make a contribution to St. Jude Children's Research Center.

"Him winning the lottery was just his luck," Ansari told ABC News. "He had already worked hard to be a millionaire before it."

Jimmy Goreel, who worked at the 7-Eleven store where Khan bought the winning ticket, described him to The Associated Press as a "regular customer ... very friendly, good sense of humor, working type of guy."

Khan's unexpected death the month after his lottery win raised the suspicions of the Cook County medical examiner. There were no signs of foul play or trauma so the death initially was attributed to arteriosclerotic cardiovascular disease, which covers heart attacks, stroke or ruptured aneurysms. The medical examiner based the conclusion on an external exam -- not an autopsy -- and toxicology reports that indicated no presence of drugs or carbon monoxide.

Khan was buried at Rosehill Cemetery in Chicago.

However, several days after a death certificate was issued, a family member requested that the medical examiner's office look further into Khan's death, Cook County Medical Examiner Stephen Cina said. The office did so by retesting fluid samples that had been taken from Khan's body, including tests for cyanide and strychnine.

When the final toxicology results came back in late November, they showed a lethal level of cyanide, which led to the homicide investigation, Cina said. His office planned to exhume Khan's body within the next two weeks as part of the investigation.

Melissa Stratton, a spokeswoman for the Chicago Police Department, confirmed it has been working closely with the medical examiner's office. The police have not said whether or not they believe Khan's lottery winnings played a part in the homicide.

Khan had elected to receive the lump sum payout of $425,000, but had not yet received it when he died, Ansari told the AP, adding that the winnings now are tied up as a probate matter.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Authorities also have not revealed the identity of the relative who suggested the deeper look into Khan's death. Ansari said it was not her, though she told the AP she has subsequently spoken with investigators.

"This is been a shock for me," she told ABC News. "This has been an utter shock for me, and my husband was such a goodhearted person who would do anything for anyone. Who would do something like this to him?

"We were married 12 years [and] he treated me like a princess," she said. "He showered his love on me and now it's gone."
