Scientific Results From Challenger Deep

Jane J. Lee


The spotlight is shining once again on the deepest ecosystems in the ocean—Challenger Deep in the Mariana Trench (map) and the New Britain Trench near Papua New Guinea. At a presentation today at the American Geophysical Union's conference in San Francisco, attendees got a glimpse into these mysterious ecosystems nearly 7 miles (11 kilometers) down, the former visited by filmmaker James Cameron during a historic dive earlier this year.

Microbiologist Douglas Bartlett with the University of California, San Diego described crustaceans called amphipods—oceanic cousins to pill bugs—that were collected from the New Britain Trench and grow to enormous sizes five miles (eight kilometers) down. Normally less than an inch (one to two centimeters) long in other deep-sea areas, the amphipods collected on the expedition measured 7 inches (17 centimeters). (Related: "Deep-Sea, Shrimp-like Creatures Survive by Eating Wood.")

Bartlett also noted that sea cucumbers, some of which may be new species, dominated many of the areas the team sampled in the New Britain Trench. The expedition visited this area before the dive to Challenger Deep.

Marine geologist Patricia Fryer with the University of Hawaii described some of the deepest seeps yet discovered. These seeps, where water heated by chemical reactions in the rocks percolates up through the seafloor and into the ocean, could offer hints of how life originated on Earth.

And astrobiologist Kevin Hand with the Jet Propulsion Laboratory in Pasadena, California, spoke about how life in these stygian ecosystems, powered by chemical reactions, could parallel the evolution of life on other planets.

Subway Push Murder Suspect Implicated Self: Police













A suspect believed to be responsible for throwing a man into the path of an oncoming New York City subway train who was taken into custody today has made statements implicating himself, police said.


According to Deputy Commissioner for Public Information Paul Browne, the suspect has been questioned by police since at least early afternoon and while the suspect is in police custody, he has not been officially charged.


Police are continuing to question the suspect and more lineups have been scheduled for tomorrow, Browne said.


Police have not released the suspect's name but began questioning him Tuesday afternoon about the death of Ki-Suck Han, 58, of Queens, N.Y.


Han was tossed onto the subway track at 49th Street and Seventh Avenue around 12:30 p.m. Monday after Han confronted a mumbling man who was alarming other passengers on the train platform. Han tried to scramble back onto the platform, but was crushed by an oncoming train.


The suspect fled the station, prompting a police dragnet for a man described by witnesses and see on surveillance video as a 6-foot-tall, 200-pound black man wearing dreadlocks in his hair.


Witnesses tried to revive the victim after he was hit and provided descriptions of the suspect to police.


Dr. Laura Kaplan, medical resident at Beth Israel Medical Center who was standing on the platform during the incident rushed to give Han aid after he was hit, she said in a statement released by her medical practice today.

"A security guard and I performed 3-4 minutes of chest compressions. I hope the family may find some comfort in knowing about the kindness of these good Samaritans, as they endure this terrible loss," Kaplan said.


"I would like the family to know that many people in the station tried to help Mr. Han by alerting the subway personnel," she said.


Kaplan said she wanted to console the family of Han, who she called "a brave man trying to protect other passengers that he did not know."


The suspect had reportedly been mumbling to himself and disturbing other passengers, according to ABC News affiliate WABC. Police told WABC that the suspect could be mentally disturbed.


The suspect could be heard arguing with Han just moments before he hurled Han onto the track bed, according to surveillance video released by the police. The suspect is heard telling the victim to stand in line and "wait for the R train."


A freelance photographer for the New York Post was on the platform and said he ran towards the train flashing his camera hoping to alert the train to stop in time, but the train caught Han against the shoulder deep platform wall.


The photographer, R. Umar Abbasi, caught an eerie photo of Han with his head and arms above the platform and staring at the oncoming train.


Han was treated by EMS workers on the platform for traumatic arrest and rushed to Roosevelt Hospital, where he was pronounced dead, according to the Fire Department of New York.


"I just heard people yelling. The train came to an abrupt stop about three-quarters into the station and that's when I heard a man was hit by a train," Patrick Gomez told ABC News affiliate WABC.


Police set up a command post outside the train station Monday night searching nearby surveillance cameras to try and get a clear image of the suspect, reports WABC. They said Tuesday that the investigation is ongoing.


Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS (8477). The public can also submit tips by logging onto the Crime Stoppers website at www.nypdcrimestoppers.com or by texting their tips to 274637 (CRIMES) then enter TIP577. All calls are strictly confidential.

Tough new anti-dumping measures in Australia






SYDNEY: Australia Tuesday announced tough new anti-dumping measures to counter an influx of cheap products that are hurting its struggling manufacturing industry and costing jobs.

Prime Minister Julia Gillard said the moves would "deliver stronger protection for Australian industry against unfair competition from overseas".

"It is not acceptable for Australian jobs to be put at risk by products being dumped into this country," she said, while refusing to single out any specific nations or put a value on dumped goods.

Dumping refers to the unfair trade practice where imported goods are sold at prices below their normal value, hurting local businesses and their workers.

"The government will support manufacturing by strengthening the system for investigating dumping and applying remedies where dumping is injuring local producers," Gillard said.

The measures include establishing a new Anti-Dumping Commission to probe complaints while boosting funding to Customs by nearly A$25 million (US$26 million) so it can double the number of investigators.

New laws will also be introduced to deal with overseas producers who deliberately circumvent Australia's anti-dumping rules.

Australia's manufacturing industry employs a million people with products affected by dumping in recent years including steel, chemicals, aluminium goods and paper products.

While Australia's mining-driven economy dodged recession during the global financial crisis, its manufacturers have been hit not only by cheap dumped products, but a high Australian dollar and intense global competition.

The Construction, Forestry, Mining and Energy Union, which has long campaigned with other unions for a dedicated anti-dumping commission, welcomed the announcement.

"Australian industry and jobs have been suffering from the impact of dumped goods for too long," said CFMEU national secretary Michael O'Connor.

"This new agency should help level the playing field for locally produced goods through investigating and penalising dumpers."

Burney writes to Pak PM, president condemning temple demolition

AMRITSAR: Pakistan's former federal minister for human rights Ansar Burney has shot off letters to Pakistan's prime minister and president seeking immediate action against the real estate builder on whose behest the century-old Sri Rama Pir temple in Karachi was demolished on Saturday.

Talking to TOI over phone from Karachi, Burney said that it was a case of blasphemy and government of Pakistan should deal with iron hand against the persons responsible for demolition of the temple.

Karachi based President of Pak Hindu Seva Trust, Sanjesh S Dhanja said that there was great disappointment among Hindus of Pakistan following demolition of temple. "I wonder that despite stay orders, how could anyone demolish the temple?," he questioned, adding that Hindus of Pakistan believed in police and judiciary of the country.

Delhi Minorities Commission has also condemned demolition of the temple and has demanded from Pakistan government to reconstruct the temple to restore confidence among the minority Hindu community in Pakistan. Chairman, Delhi Minorities Commission, Safdar H Khan said that razing of a religious place of any community was the most deplorable act. Khan, who is also vice-president of India Islamic Cultural Center said that he would write to Pakistan high commission to express his resentment and would also demand reconstruction of the temple by Pakistan government.

Mars Rover Detects Simple Organic Compounds


NASA's Mars rover Curiosity has detected several simple carbon-based organic compounds on Mars, but it remains unclear whether they were formed via Earthly contamination or whether they contain only elements indigenous to the planet.

Speaking at the American Geophysical Union annual meeting in San Francisco, Curiosity mission leaders also said that the compound perchlorate—identified previously in polar Mars—appeared to also be present in Gale Crater, the site of Curiosity's exploration.

The possible discovery of organics—or carbon-based compounds bonded to hydrogen, also called hydrocarbons—could have major implications for the mission's search for more complex organic material.

It would not necessarily mean that life exists now or ever existed on Mars, but it makes the possibility of Martian life—especially long ago when the planet was wetter and warmer—somewhat greater, since available carbon is considered to be so important to all known biology.

(See "Mars Curiosity Rover Finds Proof of Flowing Water—A First.")

The announcements came after several weeks of frenzied speculation about a "major discovery" by Curiosity on Mars. But project scientist John Grotzinger said that it remains too early to know whether Martian organics have been definitely discovered or if they're byproducts of contamination brought from Earth.

"When this data first came in, and then was confirmed in a second sample, we did have a hooting and hollering moment," he said.

"The enthusiasm we had was perhaps misunderstood. We're doing science at the pace of science, but news travels at a different speed."

Organics Detected Before on Mars

The organic compounds discovered—different combinations of carbon, hydrogen, and chlorine—are the same or similar to chlorinated organics detected in the mid-1970s by the Viking landers.

(Related: "Life on Mars Found by NASA's Viking Mission?")

At the time, the substances were written off as contamination brought from Earth, but now scientists know more about how the compounds could be formed on Mars. The big question remains whether the carbon found in the compounds is of Martian or Earthly origin.

Paul Mahaffy, the principal investigator of the instrument that may have found the simple organics—the Sample Analysis at Mars (SAM)—said that while the findings were not "definitive," they were significant and would require a great deal of further study.

Mahaffy also said the discovery came as a surprise, since the soil sample involved was hardly a prime target in the organics search. In fact, the soil was scooped primarily to clean out the rover's mobile laboratory and soil-delivery systems.

Called Rocknest, the site is a collection of rocks with rippled sand around them—an environment not considered particularly promising for discovery. The Curiosity team has always thought it had a much better chance of finding the organics in clays and sulfate minerals known to be present at the base of Mount Sharp, located in the Gale Crater, where the rover will head early next year.

(See the Mars rover Curiosity's first color pictures.)

The rover has been at Rocknest for a month and has scooped sand and soil five times. It was the first site where virtually all the instruments on Curiosity were used, Grotzinger said, and all of them proved to be working well.

They also worked well in unison—with one instrument giving the surprising signal that the minerals in the soil were not all crystalline, which led to the intensive examination of the non-crystalline portion to see if it contained any organics.

Rover Team "Very Confident"

The simple organics detected by SAM were in the chloromethane family, which contains compounds that are sometimes used to clean electronic equipment. Because it was plausible that Viking could have brought the compounds to Mars as contamination, that conclusion was broadly accepted.

But in 2010, Chris McKay of NASA's Ames Research Center and Rafael Navarro-Gonzalez of the National Autonomous University of Mexico published an influential paper describing how dichloromethane can be a byproduct of the heating of other organic material in the presence of the compound perchlorate.

They conducted the experiment because NASA's Phoenix mission had discovered large amounts of perchlorate in the northern polar soil of Mars, and it seems plausible that it would exist elsewhere on the planet.

"In terms of the SAM results, there are two important conclusions," said McKay, a scientist on the SAM team.

"The first is confirming the perchlorate story—that it's most likely there and seems to react at high temperatures with organic material to form the dichloromethane and other simple organics."

"The second is that we'll have to either find organics without perchlorates nearby, or find a way to get around that perchlorate wall that keeps us from identifying organics," he said.

Another SAM researcher, Danny Glavin of Goddard, said his team is "very confident" about the reported detection of the hydrocarbons, and that they were produced in the rover's ovens. He said it is clear that the chlorine in the compounds is from Mars, but less clear about the carbon.

"We will figure out what's going on here," he said. "We have the instruments and we have the people. And whatever the final conclusions, we will have learned important things about Mars that we can use in the months ahead."

Author of the National Geographic e-book Mars Landing 2012, Marc Kaufman has been a journalist for more than 35 years, including the past 12 as a science and space writer, foreign correspondent, and editor for the Washington Post. He is also author of First Contact: Scientific Breakthroughs in the Hunt for Life Beyond Earth, published in 2011, and has spoken extensively to crowds across the United States and abroad about astrobiology.

Kate's Illness Sometimes Linked to Twins













Hyperemesis gravidarum, the reason newly pregnant Kate Middleton is in the hospital, is a rare but acute morning sickness that results in weight loss and accounts for about 2 percent of all morning sickness, doctors say.


The condition is sometimes associated with women having twins, experts said.


Women diagnosed with hyperemesis gravidarum have lost 5 percent of their pre-pregnancy weight, or 10 pounds, said Dr. Ashley Roman, a professor and OB/GYN at New York University Langone Medical Center.


It poses little danger to the tiny heir, doctors said.


"It's traditionally thought that nausea and vomiting is a sign of a healthy pregnancy," Roman said


Dr. Nancy Cossler, an OB/GYN at University Hospitals in Ohio said the condition does not cause loss of pregnancy or birth defects, but it can be a torture to endure.


"The biggest problem with this is how it interferes with your life," Cossler said. "Constantly feeling sick and puking is difficult."

Hyperemesis gravidarum is thought to be caused by higher levels of the pregnancy hormone, hCG, or human chorionic gonadotropin, Cossler said. Extra hCG can often be brought on by carrying more than one fetus, she said.

In other words, it could be a sign that Middleton is carrying twins. Although there's very little data on twins and hyperemesis gravidarum, one study showed that women carrying twins had a 7.5 percent higher risk of experiencing the acute morning sickness, Roman said.


The extreme morning sickness is usually diagnosed about nine weeks into the pregnancy, and in most cases resolves itself by 16 or 20 weeks, Roman said. In rare cases, it can last the whole pregnancy.


"As the pregnancy is in its very early stages, Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter," a statement from St. James Palace said. Prince William is at the hospital with Middleton, according to the Britain's Press Association.

Roman said doctors prescribe vitamins and ginger capsules at first. If that doesn't stop the vomiting, they will prescribe antihistamines and stronger anti-nausea medications.


Women with hyperemesis gravidarum are also treated with fluids, said Dr. Jessica Young, an OB/GYN at Vanderbilt University. But if left untreated, a pregnant woman who is severely dehydrated for a long period of time could die, "just like any person," Young said.


In extreme cases in which the woman is losing weight and unable to eat, doctors will treat her with intravenous nutrition, Young said.


Hospital stays can vary, and women will often have to be admitted more than once before the condition passes, doctors said.


Hyperemesis gravidarum is somewhat mysterious because some expectant mothers have acute morning sickness during only one of their pregnancies, but have no morning sickness for subsequent pregnancies.


There is a chance that higher levels of hCG, which likely caused Middleton's nausea, could be a sign of a molar pregnancy instead of twins, Cossler said. This would mean Middleton is carrying only a benign growth in her uterus instead of a fetus, or she is carrying a fetus with abnormal DNA and a benign growth. Neither is considered a viable pregnancy.


However, Cossler said molar pregnancies become apparent early on, and doctors would already know whether Middleton had one.


"They would not have released this information," Cossler said of the birth announcement. "I'm certain that they have already eliminated both of those [types of molar pregnancies]."

SIA in talks to sell off Virgin Atlantic stake






SINGAPORE: Singapore Airlines said on Monday it was in talks with "interested parties" on a possible sale of its 49 per cent stake in Virgin Atlantic as media reports listed US carrier Delta Air Lines as a possible buyer.

"Singapore Airlines wishes to announce that it is in discussions with interested parties concerning the possible divestment of its 49 per cent shareholding in Virgin Atlantic Limited," the carrier said in a statement.

"These discussions may or may not result in a transaction," it added without naming any of the parties involved in the talks.

Virgin Atlantic was founded by British transport mogul Richard Branson in 1984, with the flamboyant entrepreneur owning a majority 51 per cent stake in the airline.

Britain's Sunday Times newspaper identified Delta as one of the interested parties and reported that the US carrier had approached SIA directly over the stake, which SIA had paid 600 million pounds for in 1999.

If the sale goes through, Delta's European partner, Air France-KLM, may then buy part of Branson's 51 per cent stake which would see him losing control for the first time of the airline he founded, the report added.

Delta was not immediately available for comment.

FDI in retail to safeguard international market mafias' interest: BJP

ANI Dec 1, 2012, 03.28PM IST

NEW DELHI: India's main opposition Bharatiya Janata Party (BJP) today said retail reform is a step taken by the Congress led-federal government to safeguard the interests of the international market mafias at the cost of national interest.

BJP vice president Mukhtar Abbas Naqvi said on Saturday that voting inside the parliament would decide as to who is in favour of national interest and who is working for international interests.

"The government feels that their responsibility is to safeguard the interest of international market mafias instead of national interest and for saving the interest of international market mafias, the government is ready to compromise with national interests. Now, the parliament will decide as to who is in support of international market mafias and who are supporting national interests," said Naqvi.

The government's decision to allow foreign supermarket chains such as Wal-Mart had triggered protest not only from opposition parties but also from some of its allies.

BJP had sought debate on the issue of allowing Foreign Direct Investment (FDI) in the retail sector, under the rule that entails voting after discussions.

Meanwhile, Minister in the Prime Minister Office (PMO), V Narayanaswamy said the government would answer all the queries raised by the opposition parties in the parliament and will explain the benefits of allowing FDI in retail sector.

The lower house of parliament has set December 04 and 05 as the date to vote and debate on FDI. The dates for the upper house are yet to be decided.

Narayanaswamy said the government is confident of becoming victorious in the debate.
