Plants Grow Fine Without Gravity


When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Baby Gabriel's Mother Sentenced to Prison













Elizabeth Johnson -- who at one point admitted to killing her son, the missing infant Gabriel Johnson, before saying she gave him away -- told a judge she "deserved the maximum" sentence, before receiving a prison term of 5.25 years, half of the max.


In October, Johnson, 26, was found guilty of custodial interference and unlawful imprisonment stemming from the disappearance of her 8-month-old son, last seen on Dec. 24, 2009. The baby's whereabouts remain unknown.


"I am brokenhearted over my son still being missing," said Johnson, wearing a striped prison jumpsuit. "I'm at a loss because I do deserve the max. What I have done is unconscionable. I would convict myself.


"I do deserve the maximum, I do," she said through tears. "[But it] wasn't how [the prosecution] made it out to be. It wasn't like that. That's all I have to say."


Judge Paul McMurdie said he wished he could design a sentence that would compel Johnson to disclose Gabriel's whereabouts, but could only "sentence her for the offenses [for which] she's been convicted."


Johnson, 26, will serve 5.25 years in an Arizona state prison, followed by four years of probation.










At today's sentencing hearing, prosecutor Angela Andrews called Johnson' actions "despicable," but said the state would drop its request to see Johnson serve out a maximum sentence if she would tell authorities where her son could be found.


Johnson, who has been in jail for the past three years, faced a maximum of 9.5 years in prison on the two convictions. In October, the jury did not reach a verdict on a third charge of kidnapping.


Before Gabriel's disappearance, Johnson had been embroiled in a custody battle with the baby's biological father, Logan McQueary. The couple differed on putting their infant son up for adoption. Johnson had wanted to, McQueary did not.


"I think Elizabeth should be held accountable for her actions, for making my son disappear," Johnson told the court. "She should stay in jail until Gabriel is found or be given the maximum sentence as possible."


While she was fighting with McQueary over custody of their son, Johnson left Tempe, Ariz., with Gabriel and traveled to San Antonio, Texas, on Dec. 18, 2009. Johnson failed to bring Gabriel back to visit with McQueary two days later, violating a court custody order.


Gabriel was last seen with his mother on Dec. 26, 2009. The following day, Johnson sent text messages to McQueary saying she had killed him. Johnson was recorded telling McQueary that she suffocated their son with a towel until he turned blue. She said she then put his body in a diaper bag and put the bag in the trash.


Later, Johnson told authorities she gave Gabriel to a couple she met in a park in San Antonio, though she has never named who she gave the child to.

Indonesia anti-graft agency probes sports minister






JAKARTA: Indonesia's anti-corruption agency has named the country's sports minister as a suspect in a multi-million-dollar graft case, in the latest scandal to hit the president's party ahead of the 2014 elections.

The Corruption Eradication Commission (KPK) asked authorities late Thursday to ban sports minister Andi Mallarangeng from travelling as it probes the construction of a sports centre built on the outskirts of the capital Jakarta.

The KPK said in a statement it was conducting an investigation into corruption "regarding the construction of the Hambalang sports facilities and infrastructure between 2010 and 2012, carried out by suspect Andi Alfian Mallarangeng".

The contracts to build the sports facility were worth 2.5 trillion rupiah ($261 million).

The KPK has named several members of President Susilo Bambang Yudhoyono's Democratic Party as suspects in various cases in the recent years, threatening the ruling party's position ahead of mid-year elections in 2014.

The KPK this year prosecuted the party's former treasurer Muhammad Nazaruddin, who is now also implicated in the sports centre case.

Tribal women wage war against IMFL

SHIMLA: Tribal women in Lahaul-Spiti and Kinnaur district have waged a unique war to curb social inequality, especially during marriages and other social functions. In a bid to curb show of wealth, women have come up with unique idea of banning the use of English liquor and those defying ban are being imposed heavy penalty.

Liquor is an important part of tribal customs and social get together are incomplete if alcohol and mutton are not served to guests. Since ages, tribals in Kinnaur are brewing liquor locally known as "angoori" while in Lahaul-Spiti they make it from wheat. But with the coming of wealth locally brewed liquor was replaced by whisky and beer resulting into social inequality widening the gap between rich and poor.

Noted social activist of Kinnaur and chairperson of Kinnaur Mahila Kalyan Parishad Ratan Manjari said over the years serving English liquor and beer during marriages and other social functions had become a show of wealth and those not having money too were serving it and get burdened with debt. "Trend was wrong which needed to be stopped and now we have done it in many villages of Kinnaur," she said. Kinnaur Mahila Kalyan Parishad has 200 mahila mandals as its members.

Ratan Manjari said for 5-6 years, they have mobilized support of women in Kinnaur district to tell them how use of English liquor and beer during marriages is resulting in waste of money besides creating divide among rich and poor. "Today, we have succeeded in banning English liquor in social functions, especially in Kalpa, Sangla, Lippa and other areas of district," she said.

To ensure that people obey the decision, a provision of imposing fine has been made by women amicably. "We have decided to impose penalty of Rs 5,000 on people serving the English liquor and those consuming it," Manjari said. She said still a lot more is required to be done.

In Lahaul-Spiti district, Udaipur village is setting an example for others by observing complete ban on English liquor and beer during social gathering for last three years. "During marriages and other functions only locally made liquor is served. Those defying ban are punished by mahila mandal members," said Hemvati, Mahila Mandal member of Udaipur.

Hemvati said if a family in the village found serving English liquor and Beer despite ban, then Rs 10,000 fine is imposed, but if same offence is committed second time then the family is boycotted socially.

"Such decisions are in larger interest of society as seeing rich people serving liquor even poor were following the trend after borrowing money. In one wedding, people were usually spending Rs 50,000 to 1 lakh only on liquor, but now with ban enforced in many villages show of wealth has been curbed in the interest of poor," said Rigzin Samphel Hayerpa, Zila Parishad member from Kolang in Lahaul-Spiti.

John McAfee Out of Hospital, Back in Cell













Software millionaire John McAfee has been returned to an immigration detention cell in Guatemala after being rushed to a Guatemala City hospital via ambulance.


McAfee, 67 -- who soon may be deported back to Belize, where authorities want to question him about the shooting death of his neighbor -- was reportedly found prostrate on the floor of his cell and unresponsive.


He was wheeled into the hospital on a gurney. Photographers followed in pursuit right into the emergency room, but as emergency workers eased McAfee's limp body from the gurney and onto a bed and began to remove his suit, he suddenly spoke up, saying, "Please, not in front of the press."


Earlier today, McAfee had complained of chest pains, raising concerns he might be having a heart attack.


However, that did not appear to be the case. Hours after his emergency, hospital officials sent McAfee back to the detention center, telling ABC News they found no reason to keep him overnight.


In a phone interview overnight, McAfee told ABC News, "I simply passed out, everything went black."


He said he hit his head on the floor when he collapsed. McAfee explained that for the past 48 hours he hasn't eaten and had very little to drink.


McAfee had been scheduled to be deported to Belize, ABC News has learned. But a judge could stay the ruling if it is determined that McAfee's life is threatened by being in Belizean custody, as McAfee has claimed in the past several weeks.


McAfee's attorneys hope to continue delaying the deportation by appealing to the Guatemala's high court on humanitarian grounds.


Raphael Martinez, a spokesman for the Belize government, said that if McAfee is deported to Belize, he would immediately be handed over to police and detained for up to 48 hours unless charges are brought against him.


"There is more that we know about the investigation, but that remains part of the police work," he said, hinting at possible charges.


He added that a handover by Guatemala would be "the neighborly thing to do."


A spokesman for the U.S. embassy in Guatemala said that "due to privacy considerations," the embassy would "have no comment on the specifics of this situation," but that, "U.S. citizens are subject to the laws of the countries in which they are traveling or residing, and must work within the host countries' legal framework."

Just hours before McAfee's arrest, he told ABC News in an exclusive interview Wednesday he would be seeking asylum in Guatemala. McAfee was arrested by the Central American country's immigration police and not the national police, said his attorney, who was confident his client would be released within hours.


"Thank God I am in a place where there is some sanity," said McAfee before his arrest. "I chose Guatemala carefully."


McAfee said that in Guatemala, the locals aren't surprised when he says the Belizean government is out to kill him.


"Instead of going, 'You're crazy,' they go, 'Yeah, of course they are,'" he said. "It's like, finally, I understand people who understand the system here."


But McAfee added he has not ruled out moving back to the United States, where he made his fortune as the inventor of anti-virus software, and that despite losing much of his fortune he still has more money than he could ever spend.


In his interview with ABC News, a jittery, animated but candid McAfee called the media's representation of him a "nightmare that is about to explode," and said he's prepared to prove his sanity.


McAfee has been on the run from police in Belize since the Nov. 10 murder of his neighbor, fellow American expatriate Greg Faull.


During his three-week journey, said McAfee, he disguised himself as handicapped, dyed his hair seven times and hid in many different places during his three-week journey.


He dismissed accounts of erratic behavior and reports that he had been using the synthetic drug bath salts. He said he had never used the drug, and said statements that he had were part of an elaborate prank.


Investigators said that McAfee was not a suspect in the death of the former developer, who was found shot in the head in his house on the resort island of San Pedro, but that they wanted to question him.


McAfee told ABC News that the poisoning death of his dogs and the murder just hours later of Faull, who had complained about his dogs, was a coincidence.


McAfee has been hiding from police ever since Faull's death -- but Telesforo Guerra, McAfee's lawyer in Guatemala, said the tactic was born out of necessity, not guilt.


"You don't have to believe what the police say," Guerra told ABC News. "Even though they say he is not a suspect they were trying to capture him."


Guerra, who is a former attorney general of Guatemala, said it would take two to three weeks to secure asylum for his client.


According to McAfee, Guerra is also the uncle of McAfee's 20-year-old girlfriend, Samantha. McAfee said the government raided his beachfront home and threatened Samantha's family.


"Fifteen armed soldiers come in and personally kidnap my housekeeper, threaten Sam's father with torture and haul away half a million dollars of my s***," claimed McAfee. "If they're not after me, then why all these raids? There've been eight raids!"


Before his arrest, McAfee said he would hold a press conference on Thursday in Guatemala City to announce his asylum bid. He has offered to answer questions from Belizean law enforcement over the phone, and denied any involvement in Faull's death.

Japan polls tip big win for opposition






TOKYO: Japan's main opposition party will comfortably win the general election this month, opinion polls showed Thursday, the first time surveys have indicated anything other than a fragile coalition.

The hawkish chief of the conservative Liberal Democratic Party (LDP) Shinzo Abe is also tipped to win back the premiership, an office he held for around a year until 2007, according to a telephone poll conducted by Kyodo news agency.

The LDP is on course to win up to 306 of the 480 seats in lower house of parliament on December 16, with the projected tally representing a huge jump from the 118 seats the party currently has.

The survey of 123,700 eligible voters showed Prime Minister Yoshihiko Noda's Democratic Party of Japan (DPJ) will see its number of seats plunge to between 57 and 82 from the 308 it swept to power with in 2009.

Around 1,500 candidates, fielded by 12 parties or standing as independents, are vying for the 480 seats -- 300 in single-seat constituencies and 180 allocated for proportional representation in 11 blocs.

Previous opinion polls have shown a much tighter race, with commentators expecting the election would leave Japan with a fragile coalition government.

Kyodo noted about half the voters said they had not yet decided on who to vote for.

Similar surveys by the mass-circulation Asahi and Yomiuri dailies, released Thursday, also showed the LDP was gaining momentum and was on course to win a single-party majority.

The Kyodo survey said the LDP's potential junior coalition partner New Komeito party is likely to win between 25 and 31 seats.

If the two parties joined forces they would have a two-thirds majority in the powerful lower house, giving them the right to overrule the DPJ-dominated upper house.

The Japan Restoration Party, an unwieldy coalition of followers of Osaka's outspoken mayor Toru Hashimoto and of the China-bashing former governor of Tokyo, Shintaro Ishihara, is likely to become a third-largest party, the polls showed.

The Tomorrow Party of Japan, a hastily cobbled-together grouping of DPJ malcontents and a left-leaning newcomers pledging to end Japan's nuclear power programme in 10 years, could have just 15 seats.

This month's vote is being seen as a verdict on the DPJ's three-year rule, which included the turbulent months after the nuclear disaster plunged the nation into its biggest crisis since World War II.

Nasa releases satellite imagery of India on Diwali night

WASHINGTON: Nasa, the national space agency of the US, today released a black and white satellite imagery of India this Diwali night, cautioning people against the fake image in circulation on the social media.

"On November 12, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime view of southern Asia," Nasa said releasing a picture of India on this Diwali night.

"The image is based on data collected by the VIIRS 'day- night band', which detects light in a range of wavelengths from green to near-infrared. The image has been brightened to make the city lights easier to distinguish," it said.

Nasa said most of the bright areas in the imagery released by it are cities and towns in India, the country with the world's largest Hindu population.

"India is home to more than 1.2 billion people and has 30 cities with populations over 1 million. (For comparison, China has 62 cities with more than 1 million residents and the United States has 9)," it said.

Cities in Bangladesh, Nepal, and Pakistan are also visible near the edges of the image.

"An image that claims to show the region lit for Diwali has been circulating on social media websites and the Internet in recent years. In fact, it does not show what it claims. That image, based on data from the Operational Linescan System flown on US Defense Meteorological Satellite Program (DMSP) satellites, is a color-composite created in 2003 by NOAA scientist Chris Elvidge to highlight population growth over time," Nasa said.

"In that image, white areas show city lights that were visible prior to 1992, while blue, green, and red shades indicate city lights that became visible in 1992, 1998, and 2003 respectively," it said.

"In reality, any extra light produced during Diwali is so subtle that it is likely imperceptible when observed from space," Nasa said.
