Sandy storm victims react to proposed home buyout

Labels: Health

(CBS News) STATEN ISLAND, N.Y. - One hundred days ago, the Northeast was hit by a left hook from superstorm Sandy.

This week, New York Gov. Andrew Cuomo proposed spending $400 million to buy up and demolish thousands of those homes, so the property can be turned back into wetlands.

Homeowners have mixed feelings about the proposal.

For 11 years, Joe Monte worked two jobs and spent weekends renovating his Staten Island home. Weeks after he finished last fall, superstorm Sandy swept eight feet of water inside.

"I came into the house with paper towels and some Fantastic, and I stood in the middle of the room and called my wife and I told my wife, 'There's nothing to clean here, there's nothing to do. It's done,'" Monte said.

Monte welcomes Cuomo's proposal to buy up properties like his in flood-prone areas.

"This isn't my dream, the poison that's in this home, the destruction that took this neighborhood. How could you even stay here?" he said. "How could you even live in this neighborhood?"

But about 30 miles away in Long Beach, N.Y., Fran Adelson plans to stay and rebuild. She, too, lost almost everything in the storm.

"We live here. This is where our homes are, this is where our children were raised, this is where our families are, this is where the businesses that we go to are," she said.

She believes the governor should be looking at ways to help people stay in their communities.

"We would rather see Cuomo spend the money on helping us rebuild than offering to buy people's property," Adelson said.

But Joe Monte says he's had enough. He's walking away.

"I hate that I lost neighbors in my neighborhood," he said. "Three people died in this neighborhood. I hate everything about it. I could never come back here ever again."

Gov. Cuomo's buyout proposal still has to be approved by the federal government. If it is approved, the governor's office says they won't force people to sell their property -- but those who do decide to stay would be offered grants to rebuild their homes.

Lance Armstrong Under Criminal Investigation

Labels: Business

Federal investigators are in the midst of an active criminal investigation of disgraced former Tour de France champion Lance Armstrong, ABC News has learned.

The revelation comes in stark contrast to statements made by the U.S. Attorney for Southern California, Andre Birotte, who addressed his own criminal inquiry of Armstrong for the first time publicly on Tuesday. Birotte's office spent nearly two years investigating Armstrong for crimes reportedly including drug distribution, fraud and conspiracy -- only to suddenly drop the case on the Friday before the Super Bowl last year.

Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.

Today, a high level source told ABC News, "Birotte does not speak for the federal government as a whole."

According to the source, who agreed to speak on the condition that his name and position were not used because of the sensitivity of the matter, "Agents are actively investigating Armstrong for obstruction, witness tampering and intimidation."

An email to an attorney for Armstrong was not immediately returned.

Earlier Tuesday, during a Department of Justice news conference on another matter, Birotte was confronted with the Armstrong question unexpectedly. The following is a transcript of that exchange:

Q: Mr. Birotte, given the confession of Lance Armstrong to all the things --

Birotte: (Off mic.)

Q: -- to all thethings that you, in the end, decided you couldn't bring a case about, can you give us your thoughts on that case now and whether you might take another look at it?

Birotte: We made a decision on that case, I believe, a little over a year ago. Obviously we've been well-aware of the statements that have been made by Mr. Armstrong and other media reports. That has not changed my view at this time. Obviously, we'll consider, we'll continue to look at the situation, but that hasn't changed our view as I stand here today.

The source said that Birotte is not in the loop on the current criminal inquiry, which is being run out of another office.

Armstrong confessed to lying and using performance-enhancing drugs throughout his career in an interview with Oprah Winfrey.

Investigators are not concerned with the drug use, but Armstrong's behavior in trying to maintain his secret by allegedly threatening and interfering with potential witnesses.

Armstrong is currently serving a lifetime ban in sport handed down by the U.S. Anti-Doping Agency. He has been given a Feb. 6 deadline to tell all under oath to investigators or lose his last chance at a possible break on the lifetime ban.

Ice-age art hints at birth of modern mind

Labels: World

Figurines from the Don river valley (Images: Kirstin Jennings)

The world’s oldest portrait, the world’s first fully carved sculpture, the world's oldest ceramic figure, the world’s earliest puppet - there’s no shortage of superlatives in the new exhibition of art from the ice age at the British Museum in London

But focus too closely on the exhibits’ record-breaking ages alone, and you might miss the broader point: these beautiful objects are the earliest evidence we have of humans who seem to have had minds like ours.

Consider, for example, the "lion man" found in 1939 in south-west Germany’s Stadel cave (pictured above). As the name suggests, this statue, standing 30 centimetres tall, harmoniously combines human and leonine features: the head is unmistakeably a lion’s, while the body and lower limbs are more human.

This is clearly the product of artistic creativity rather than a naturalistic drawing from life - suggesting that whoever carved it some 40,000 years ago had the capacity to express their imagination, as well as to replicate what they saw around them.

The temptation to speculate about what symbolic meaning the lion man might have had is, of course, irresistible. It was clearly valuable, taking around 400 hours and enormous skill to carve from a single piece of mammoth ivory.

The exhibition also includes a second, much smaller, feline figure found in another cave nearby, pointing to the idea that such imaginative objects might have cultural significance, perhaps as ritual objects within a shamanic belief system, rather than being isolated art objects.

Given what we know of modern traditions, that would make sense - but there is no hard evidence that anything resembling those traditions existed in Europe during the ice age.

Almost every object on show invites similarly thought-provoking consideration. Thumb-sized figurines from settlements along Russia's Don river (top) seem to present a woman's perception of her own pregnant body in an age before mirrors: no face, bowed head, the shelf of the bosom, the protrusion of the hips and buttock muscles and the swell of the belly. Were they carved by the women themselves, perhaps as protective talismans for themselves or their unborn children? And if so, what are we to make of those that were apparently deliberately destroyed subsequently?

Only a few of the animal models found at the Czech site of Dolní Věstonice are intact. The rest had shattered into thousands of clay fragments when they were heated while still wet. This must also have been deliberate: was the dramatic shattering part of a rite?

A tiny relief of a human figure with upraised arms invites interpretation as a celebrant or worshipper. Was he or she participating in a ceremony to promote social cohesion during tough times - perhaps to the accompaniment of music played on instruments such as the flute displayed nearby, which is precisely carved from a vulture's wing-bone?

Such interpretations deserve a healthy dose of caution, of course. The note accompanying an elegantly carved water bird (perhaps a cormorant) found near the smaller lion man drily reads: "This sculpture may be a spiritual symbol connecting the upper, middle and lower worlds of the cosmos reached by a bird that flies in the sky, moves on land and dives through water. Alternatively, it may be an image of a small meal and a bag of feathers."

In the total absence of documentary evidence, there is no way of telling which is correct: archaeological material might help clarify the utilitarian perspective, but it is far less helpful when it comes to discovering any symbolic value.

In any case, there is very little archaeological evidence on display at the British Museum. Curator Jill Cook says she was keen to avoid exhausting visitors with copious background material about the evolutionary and environmental contexts in which these objects were made.

Humans were capable of complex behaviour long before they reached Europe - as demonstrated by discoveries such as the 100,000-year old "artist's workshop" in South Africa's Blombos cave - but Cook thinks the explosion of art among Europeans 40,000 years ago may reflect changing social needs during the ice age.

When Homo sapiens first arrived in Europe some 45,000 years ago, "the living was initially probably reasonably easy", explains Cook. They would have found temperatures only about 5 °C lower than they are now, she says, and grassy prairies would have been well stocked with bison. As the human population grew, they would have had to find new ways of building, socialising and organising themselves.

“And as it turns desperately cold, around 40,000 years ago, suddenly we have all this art," she says.

That may have reflected the need to communicate and develop ideas - a need pressing enough for people to spend hundreds of hours creating objects that generally seem to have had little quotidian function.

"This is all about planning and preconceiving and organising and collaborating and compromising," suggests Cook, "and that is something art and music helps us do."

The dazzling array of objects on display, spanning tens of thousands of years, anticipate practically every modern artistic tradition. The first portrait, dating back 26,000 years, includes closely modelled details of its female subject's unusual physiognomy, perhaps the result of an injury or illness.

But nearby is an extraordinary figure of similar age whose facial features are utterly abstract, resembling a visor with a double slit in it.

Another (above) has a body whose angular patterns anticipate Cubism by some 23,000 years: Picasso kept two copies of it in his studio. Elsewhere, there are doll-like models of women with stylised faces, and female forms streamlined into little more than slender, strategically curved lines.

Representations of animals, too, come in all forms, from incredibly realistic illustrations scratched onto stone or ivory, to elegantly minimal sculptures; there are even carvings designed to create the illusion of movement when viewed from different angles or rotated (above) - a form of prehistoric animation.

The masterpieces in the latter part of the show include - and sometimes combine - both precisely observed, superbly rendered naturalism, and more abstract work that is still beautiful, but much harder to interpret.

Carved mammoth tusks

"The brain likes to tease us," says Cook. "We don't just represent things with great realism and naturalism, we like to break things down into patterns. That sparks your imagination, and makes you curious and questioning.

“What’s so spectacular about the modern brain, and the mind that it powers, is that it doesn't just make everything simple, it pushes us to new ideas and new thoughts."

After tens of thousands of years, the objects displayed in this extraordinary exhibition still have the power to do just that.

China police chief accused of having 192 houses

Labels: Technology

BEIJING: A Chinese police chief is alleged to have had at least 192 houses and a fake identity card, state media said Tuesday, the latest in a number of similar cases that have sparked outrage online.

Zhao Haibin, a senior police official in Lufeng in the southern province of Guangdong, was reported by a businessman to have accumulated the properties under his name and his company's, the Guangzhou Daily said.

The businessman, Huang Kunyi -- who was involved in a dispute with the officer -- also said Zhao used a fake identity card to record a different name on company documents, the newspaper reported.

Authorities cancelled the false card after Huang's report in 2011, it added.

An official of the Communist Party's discipline department for Lufeng told AFP Tuesday that Zhao -- who is also the vice party secretary of a local county -- had been investigated but the inquiry was over and he retained his public offices.

According to the newspaper, Zhao said the properties were owned by his younger brother, a businessman, and that he was only "managing" them for him.

A separate report said Zhao or the company had 192 properties in the city of Huizhou, also in Guangdong, and others in the cities of Shenzhen and Zhuhai.

The case is the latest of a series of reports involving officials owning multiple houses with different identity cards and residence permits.

Gong Aiai, a vice president of a bank in the northern province of Shaanxi and a delegate to the local legislature, was reported last month to hold more than 20 houses worth nearly one billion yuan (US$160 million), using four different residence permits and three identity cards.

She was detained by police Monday on suspicion of "forging official documents and stamps", the state-run Xinhua news agency reported.

The cases have sparked mounting criticism in Chinese social media over rampant graft and high home prices that are running out of reach of the average citizen.

"(I) finally realised that in China, properties are forever in the hands of a tiny number of people," said a user of China's Twitter-like Sina Weibo.

Boy safe, suspect dead after Alabama bunker standoff

STORY HIGHLIGHTS

NEW: Rescued child is in good spirits at hospital, authorities say

NEW: Officials say crime scene is still active, bomb squad on site

FBI says boy was rescued after negotiators felt he was in danger

Witness said he heard explosion followed by gunshots

Midland City, Alabama (CNN) -- A 5-year-old boy freed Monday after being held captive in an underground bunker for six days is laughing and smiling and playing with his favorite toy dinosaur after being reunited with his family, authorities said.

The boy's kidnapper is dead, but officials offered no details on the raid that freed the boy -- identified only by his first name, Ethan -- and left his abductor fatally shot.

FBI Special Agent in Charge Steve Richardson visited Ethan at a hospital, where he was in a private area with heavy security.

"He is doing fine," Richardson told reporters at a late-night news conference. "He's laughing, joking, playing, eating."

Dale County Sheriff Wally Olson had no new details about Ethan's rescue, and when asked if the boy saw his abductor, 65-year-old Jimmy Lee Dykes, killed during the rescue operation, Olson replied, "He's a very special child. He's been through a lot, he's endured a lot."

Ethan looks great but will be hospitalized overnight, an uncle told people at a prayer vigil earlier Monday.

Authorities said they were still working on the crime scene and the investigation should continue for several more days. The sheriff's office said the bomb squad was checking the bunker for potential explosive devices.

Ethan, the rescued boy, arrives on stretcher Monday at Flowers Hospital in Dothan, Alabama.

Richardson earlier said an FBI team went in to get Ethan after negotiations had broken down with Dykes, who also was "observed holding a gun."

Olson said it became very difficult to deal with and even communicate with Dykes over the past day.

Believing the child to be in imminent danger, an FBI team entered the bunker at 3:12 p.m. CT (4:12 p.m. ET) and rescued the boy, Richardson said.

One neighbor said he was outside when he was startled by the sound of an explosion.

"I heard a big boom and then ... I believe I heard rifle shots," said Bryon Martin, who owns a home near the bunker where the boy had been held since Tuesday.

It was a loud noise that "made me jump off the ground," he said.

Authorities wouldn't say whether the blast was set off as a diversionary tactic or whether Dykes had planted explosives around the bunker.

After the good news of the boy's release spread through the small rural community, travelers on a nearby highway honked their horns as they drove by.

The FBI had borrowed from the U.S. military high-tech detection equipment similar to the technology used to discover homemade bombs in war zones, three Defense Department officials told CNN.

It was unclear whether the equipment, which is not readily available to civilian law enforcement, had been used by the FBI.

One of the defense officials said no members of the military were involved in the rescue. They would have been acting a technical advisers, the official said.

Last Tuesday, police said, Dykes boarded a Dale County school bus and demanded the driver hand over two children.

The driver, Charles Albert Poland Jr., refused, blocking access to the bus's narrow aisle as at least 21 children escaped out of the back emergency door, authorities said.

The gunman killed Poland, then grabbed a kindergartner before barricading himself and the boy inside a nearby bunker he had built.

Smith said Monday that Ethan has siblings, but none of them were on the bus last week.

In the ensuing days, officials said little about what was going on in the bunker or in their strategy, or what -- if anything -- Dykes wanted.

"Based on our discussions with Mr. Dykes, he feels like he has a story that's important to him, although it's very complex," Olson said Monday before the hostage situation ended. He didn't elaborate.

Ethan suffers from Asperger's syndrome and attention deficit disorder, state Rep. Steve Clouse said during the week.

Dykes told authorities that he had blankets and a heater in the bunker, and authorities have previously said the bunker -- built 4 feet underground -- has electricity.

Authorities did not say how they were communicating with Dykes.

Meanwhile, residents and business owners in Midland City put up blue, red and black ribbons in support of the boy and Poland. Blue and red are the local school colors, and black is in honor of the slain bus driver.

The U.S. Navy confirmed Monday that Dykes served in the military from 1964 to 1969.

Naval records list him as an aviation maintenance administrationman third-class who served with units based in California and Atsugi, Japan. The job entails clerical work related to aircraft and aircraft maintenance, according to the Navy's job description.

Neighbors and officials had described Dykes as a survivalist with "anti-government" views.

Even as the hostage situation continued Monday morning, plenty of police were on hand as schools in neighboring Ozark, Alabama, reopened for the first time since the incident began.

Dale County schools remained closed but were to reopen on Tuesday, the district said.

In Ozark, school officials decided to begin strictly enforcing a 15-foot safety zone around school buses required by state law. The law prohibits any unauthorized adults, including parents, from approaching within 15 feet of a school bus stop. If an unauthorized adult gets too close, bus drivers are supposed to close bus doors or drive away, if necessary, school officials said

CNN's Victor Blackwell and Martin Savidge reported from Midland City; Barbara Starr contributed from Washington; Michael Pearson and Steve Almasy reported and wrote from Atlanta; and CNN's Vivian Kuo and Larry Shaughnessy also contributed to this report.

Ex-Navy SEAL murder suspect had been in mental hospital

Labels: Health

FORT WORTH, TexasThe Iraq War veteran charged with killing a former Navy SEAL sniper and his friend on a Texas shooting range had been taken to a mental hospital twice in the past five months and told authorities that he was suffering from post-traumatic stress disorder, police records show.

Eddie Ray Routh, 25, also told his sister and brother-in-law after the shootings that he "traded his soul for a new truck," according to an Erath County arrest warrant affidavit obtained by WFAA-TV. Police said that Routh was driving the truck of victim and ex-Navy SEAL Chris Kyle at the time of arrest.

Ex-Marine suspected of killing ex-Navy SEAL on suicide watch

Routh is charged with one count of capital murder and two counts of murder in the shooting deaths of Kyle, author of the best-selling book "American Sniper," and his friend Chad Littlefield at a shooting range Saturday in Glen Rose. He is on suicide watch in the Erath County Jail, where he's being held on $3 million bond, Sheriff Tommy Bryant said.

Routh, a member of the Marines Corps Reserve, was first taken to a mental hospital on Sept. 2 after he threatened to kill his family and himself, according to police records in Lancaster, where Routh lives. Authorities found Routh walking nearby with no shirt and no shoes, and smelling of alcohol. Routh told authorities he was a Marine veteran who was suffering from post-traumatic stress disorder.

"Eddie stated he was hurting and that his family does not understand what he has been through," the report said.

Routh's mother told police that her son had been drinking and became upset when his father said he was going to sell his gun. She said Routh began arguing with them and said he was going to "blow his brains out."

Police took Routh to Green Oaks Hospital for psychiatric care.

Dallas police records show Routh was taken back to the same mental hospital in mid-January after a woman called police and said she feared for Routh's safety.

Green Oaks will not release patient information, citing privacy laws. Most people brought by police to the hospital are required to stay at least 48 hours.

In May, Routh's mother reported a burglary that included nine pill bottles and her son was involved, according to a Lancaster police report. No other details were available.

Authorities say Routh, Kyle and Littlefield arrived at the sprawling Rough Creek Lodge at about 3:15 p.m. Saturday, and a hunting guide called 911 about two hours later after discovering the bodies. Kyle and Littlefield were shot multiple times, and numerous guns were at the scene, according to the affidavit.

After leaving the Navy, Kyle quickly found a way to maintain contact with his fellow veterans and pass on what had helped him work through his own struggles. By late 2011, he filed the paperwork to establish the nonprofit FITCO Cares, which received its nonprofit status the following spring, said FITCO director Travis Cox.

Routh drove to his sister's house, and told her that he killed two people and that he planned to drive to Oklahoma to evade Texas authorities, the affidavit said. Routh's sister then called police, and he was arrested after a short police pursuit in Lancaster.

Jailers used a stun gun on Routh on Sunday night after he appeared ready to assault them when they entered his cell after he refused to return his food tray, the sheriff said. Then they put Routh in a chair that restrains his arms and legs in his solitary confinement cell, Bryant said.

Bryant said Routh has an attorney but hasn't met with him at the jail in Stephenville, about 75 miles southwest of Fort Worth.

Attempts by The Associated Press to reach Routh's mother and sister were unsuccessful Monday.

Sundae Hughes, an aunt of Routh's, said she watched him grow up but hasn't seen him since his high school graduation in 2006. Hughes was in disbelief that her nephew could be involved in such an incident.

"He has a kind heart (and was) someone willing to jump in and help, no matter what it was," she said.

Routh joined the Marines in 2006 and rose to the rank of corporal in 2010. His military specialty was small-arms technician, commonly known as an armorer. He had been stationed at Camp Lejeune, N.C., and served in Iraq from 2007-08 and in the Haiti disaster relief mission in 2010.

He is now in the individual ready reserve. He could be called to duty, but it's uncommon unless he volunteers, 1st Lt. Dominic Pitrone of the Marine Forces Services public affairs office said.

Travis Cox, director of FITCO Cares — the nonprofit that Kyle set up to give in-home fitness equipment to physically and emotionally wounded veterans — said he believes that Kyle and Littlefield were helping Routh work through PTSD.

Cox didn't know how Routh and Kyle knew each other. He said the shooting range event was not a FITCO session.

Kyle, 38, left the Navy in 2009 after four tours of duty in Iraq, where he earned a reputation as one of the military's most lethal snipers. "American Sniper" was the No. 3 seller of paperbacks and hardcovers on Amazon as of Monday, and the hardcover was out of stock.

Kyle was so deadly accurate in combat that insurgents in Iraq put a $20,000 bounty on his head and dubbed him "The Devil of Ramadi." But to fellow SEALs like Rorke Denver, he was known as "The Legend." Denver told CBS News, "We were aware early on in that deployment that something special, for lack of a better term, was unfolding."

Littlefield, 35, was Kyle's friend, neighbor and "workout buddy," and also volunteered his time to work with veterans, Cox said.

Sarai Sierra's 2 Young Boys Don't Know Mom's Dead

Labels: Business

The two young sons of slain New York mom Sarai Sierra are under the impression that their father has gone to Turkey to bring their mother home - alive.

Sierra, whose battered body was found near a highway in Istanbul over the weekend, was the mother of two boys aged 9 and 11.

Steven Sierra, who went to Istanbul in search of his wife after she disappeared nearly two weeks ago, told his children that he was going to Turkey to bring their mom home.

"The father will be speaking to them and it's something that's going to be hard and he's going to be talking to them when he comes back," Betsy Jimenez, the mother of Sarai Sierra, said today during a family news conference.

State Representative Michael Grimm said Steven Sierra's biggest concern is telling his children that mom's not coming home.

"It's going to be the hardest thing he's ever going to have to do in his life," said Grimm, who added that the Staten Island family isn't sure when Steven Sierra will be able to bring home his wife's body.

An autopsy was completed Sunday on Sarai Sierra, 33, but results aren't expected for three months. Turkish officials however said she was killed by at least one fatal blow to her head.

A casket holding the Staten Island mother was carried through alleyways lined with spice and food stalls to a church, where the casket remained on Monday.

Turkish police hope DNA samples from 21 people being questioned in the case will be key to finding the perpetrators, the Associated Press reported, according to state run media.

Earlier this week, it was also reported that Turkish police are speaking to a local man who was supposed to meet Sierra the day she disappeared, but he said she never showed.

After an intense search for Sierra that lasted nearly two weeks, her body was found Saturday near the ruins of some ancient city walls and a highway. Sierra was wearing the same outfit she was seen wearing on surveillance footage taken at a food court and on a street the day she vanished, Istanbul Police Chief Huseyin Capkin said.

Sierra's body was taken to a morgue, Capkin said, and was identified by her husband.

It did not appear she had been raped or was involved in any espionage or trafficking, Capkin said.

Betsy Jimenez said Monday that her family has many unanswered questions such as what happened to her daughter after she left her hotel room to go and take photographs of a famous bridge.

"They're still investigating so they might think it might be a robbery, but they're not sure," said Jimenez.

Sierra, who had traveled to Istanbul on Jan. 7 to practice her photography hobby, was last heard from on Jan. 21, the day she was due to board a flight home to New York City.

Dennis Jimenez, Sierra's father, told reporters Monday that he didn't want her to go on the trip.

"I didn't want her to go. But, she wanted to go because this was an opportunity for her to sightsee and pursue her photography hobby because Turkey was a land rich with culture and ancient history and she was fascinated with that," said Jimenez.

While in Istanbul, Sierra would Skype with her family and friends daily, telling them about how amazing the culture was.

Sierra's best friend Maggie Rodriguez told ABC News that she was forced to pull out of the trip at the last minute because she couldn't afford it. That's why Sierra traveled alone.

Her husband, Steven Sierra, and brother, David Jimenez, traveled to Istanbul last Sunday to meet with American and Turkish officials and push the search forward.

Bug protects itself by turning its environment to gold

Labels: World

Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch.

Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic.

To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells.

"This could have potential for gold extraction," says Nathan Magarvey of McMaster University in Hamilton, Ontario, who led the team that uncovered the bugs' protective trick. "You could use the bug, or the molecules they secrete."

He says the discovery could be used to dissolve gold out of water carrying it, or to design sensors that would identify gold-rich streams and rivers.

The protective chemical is a protein dubbed delftibactin A. The bugs secrete it into the surroundings when they sense gold ions, and it chemically changes the ions into particles of gold 25 to 50 nanometres across. The particles accumulate wherever the bugs grow, creating patches of gold.

Deep purple gold

But don't go scanning streams for golden shimmers: the nanoparticle patches do not reflect light in the same way as bigger chunks of the metal – giving them a deep purple colour.

When Magarvey deliberately snipped out the gene that makes delftibactin A, the bacteria died or struggled to survive exposure to gold chloride. Adding the protein to the petri dish rescued them.

The bacterium Magarvey investigated is one of two species that thrive on gold, both identified a decade or so ago by Frank Reith of the University of Adelaide in Australia. In 2009 Reith discovered that the other species, Cupriavidus metallidurans, survives using the slightly riskier strategy of changing gold ions into gold inside its cells.

"If delftibactin is selective for gold, it might be useful for gold recovery or as a biosensor," says Reith. "But how much dissolved gold is out there is difficult to say."

More bus drivers from China sign up as union members

Labels: Technology

SINGAPORE: NTUC Secretary-General Lim Swee Say said there has been an increase in the number of bus drivers from China working with SMRT signing up to become union members.

Mr Lim said this in Parliament when he joined Acting Minister for Manpower Tan Chuan-Jin in his reply to questions on the SMRT bus drivers' illegal strike last year.

Mr Lim said prior to the November 2012 incident, less than five percent of the 400 drivers from China working with SMRT were union members. As of today, about 75 percent of them have signed up to be union members.

In the case of SBS Transit, Mr Lim said they have about 600 drivers from China, and more than 90 per cent are already union members.

Overall, of the 1.2 million foreign workers in Singapore, about 100,000 of them are union members making up about 15 per cent of the union membership in Singapore.
