Two Nobel Prize winners share their success stories






SINGAPORE: Fifteen internationally-renowned scientists were in Singapore recently for the inaugural Global Young Scientists Summit.

Among them were Nobel Prize winners Eric Cornell and Ada Yonath, who gave talks, participated in panel discussions and mentored young scientists during their time in Singapore.

The discoveries that garnered them the prestigious Nobel Prize were years in the making.

In 2009, Professor Yonath became the first woman in 45 years to win the Nobel Prize in Chemistry - after documenting the spatial structure of a ribosome, which are used by cells to make protein.

She said the discovery - the culmination of 20 years of research - was a dream come true.

"This was overwhelming, it is unbelievable, inside me I couldn't sleep, I saw it all the time," said Ms Yonath.

For Professor Cornell, who lost an arm to flesh-eating bacteria a few years ago, his discovery was the highlight of his career.

The physicist was one half of the duo that created a new form of matter - called a Bose-Einstein condensate, which had been predicted as early as the 1920s, but had never been proven up to that point.

Professor Cornell, who won the Nobel Prize in Physics in 2001, said: "It was exciting to win the Nobel Prize but not as exciting as it was to make the experiment work. It was 1995 when the experiment worked, I loved that! It was a sense of great power and excitement."

The loss of his left arm hasn't stopped him from going about his life and work as per normal. Professor Cornell said: "It wasn't very difficult to adapt...I am at a point in my career where I do not use my hands to adjust the apparatus.

"I have graduate students who are working, and I explain to them what to do, and they do it. So it hasn't changed my life very much. I have learnt how to type very rapidly with one hand..."

For both, science was a love affair that began when they were very young.

When she was five years old, Professor Yonath fell two floors trying to gauge the distance between the floor and the ceiling. She broke her hand in many places.

Meanwhile, Professor Cornell used to solve physics brainteasers when he had trouble falling asleep.

He said: "For me, I feel that learning physics is like discovering the secrets. You know maybe you are an actor, and performing in a play, and you get to go behind the scenes and see how the play comes together.

"I think as a physicist, it is like that. You get to go behind the scenes, find out what is really going on. I feel it is almost like secret knowledge."

And it is a love affair that has endured.

Professor Yonath said: "Once it becomes boring, I will stop. As long as it is interesting, my curiosity drives me. Passion for science and curiosity."

Both scientists said that summits which bring an international mix of young scientists together could pave the way for future collaborations.

Afzal Guru's last letter to wife yet to reach her in Kashmir

NEW DELHI: Hours before he was to be executed, Afzal Guru penned his last letter to his wife, Tihar Jail officials said on Monday. The letter, written in Urdu, was posted on Saturday but is yet to reach his wife in Kashmir.

Speaking to IANS, officials at Tihar jail said that Afzal Guru, convicted for his role in the 2001 Parliament attack, was told on February 8 evening that he would be hanged the next morning.

"When he was told about his execution, he was cool and calm. He just expressed his wish that he wants to write a letter to his wife. The jail superintendent gave him a pen and paper," an official told IANS under condition of anonymity.

"He wrote the letter in Urdu, which was posted to his family in Kashmir on the same day," the official said. However, when IANS contacted the family, who live in Sopore, they said they are yet to receive it.

"We haven't received this letter. Maybe like the letter that we got today about his hanging, we will get it later," Yaseen Guru, Afzal's cousin, told IANS on phone.

Afzal Guru was hanged on February 9 at 8am in the Tihar Jail complex where he had lived in a solitary cell for many years.

His family has demanded that they be allowed to conduct his last rites.

"The government will take a decision in this regard," another official told IANS.

Afzal Guru, who used to spend his time in the jail by reading and writing, has left behind many books and hand-written articles.

The family has asked the jail authorities that all his belongings should be returned to them.

"The government will have to take a decision on this issue," the official added.

Year of the Snake: The Serpent Behind the Horoscope


On February 10, people all around the world will ring in the Lunar New Year with paper lanterns and firecrackers. At the heart of it all sits the snake, a slithery reptile feared for its sharp fangs and revered for its undeniable charm. (Watch videos of some of the world's deadliest snakes.)

Those born in the Year of the Snake are said to be intelligent and quick thinking, but they can also be dishonest and prone to show off. Though based on Chinese astrology, some of these traits are similar to characteristics of the actual serpent.

Snakes are known to be great at outsmarting their predators and prey. Their colorful, patterned skin makes them some of the best tricksters in the animal kingdom. And despite a bad rap as frightening creatures, snakes never fail to fascinate scientists, explorers, and zoo-goers. (See pictures of snakes.)

With more than 3,400 recognized species, snakes exhibit incredible diversity in everything from behavior and habitats to skin colors and patterns.

"As a vertebrate lacking in limbs, all snakes look largely like other snakes, yet they succeed in tremendous diversity in multiple directions," said Andrew Campbell, herpetology collections manager at the University of Kansas Biodiversity Institute.

To usher in the Year of the Snake, Campbell and herpetologist Dennis Ferraro at University of Nebraska-Lincoln weigh in on some of the snake's qualities that the Chinese zodiac predicts people born this year will have.

Horoscope: Snakes have an innately elegant personality but can also be ostentatious at times.

In Nature: Snakes come in all different colors, patterns, and textures, making them some of nature's most visually stunning creatures.

According to Campbell, the utility of their coloring falls into two main categories: to use as camouflage and to warn predators to stay away.

Among the most beautiful are the emerald tree boa (Corallus caninus)—whose vibrant green body is decorated with white stripes resembling lightning bolts—and the Brazilian rainbow boa (Epicrates cenchria), characterized by its iridescent skin and the large black rings down its back.

For some snakes, the diversity in color occurs within the same species, which is why Ferraro tells his student not to identify snakes by colors. For example, the polymorphic bush viper (Atheris squamigera), many of which are green, also come in shades of yellow, orange, red, and blue, as captured in photographer Guido Mocafico's "Serpent Still Life" photo series.

Horoscope: The snake is known to be the master seducer of the Chinese zodiac.

In Nature: Female garter snakes (Thamnophis) have all the luck with the gentlemen.

When a female garter snake is ready to mate, she announces it by producing chemicals called pheromones. Males, upon encountering the scent, immediately come crawling out and gather around the female in a large, wriggling "mating ball."

The competition intensifies when a male passing by the ball tries to fool the others by producing a scent that mimics that of the female, said Ferraro.

As soon as his rivals are led off in the wrong direction, the trickster slides right in. In areas with smaller populations of garter snakes, each ball consists of about 12 males and one female.

But in places like Manitoba, Canada, where garter snakes travel to certain areas to mate after coming out of hibernation, a mating ball can have thousands of males and only a hundred females.

Horoscope: Though snakes don't often tell lies, they will use deception when they feel it's necessary and they think they can get away with it.

In Nature: When it comes to using trickery to catch dinner, or to hide from predators, snakes are no amateurs.

Their sneaky techniques range from tricking fish to swim right into their mouths, to playing dead when threatened, to using their wormlike tails to lure in prey.

The most cunning of them all is the two-headed snake. To protect against a sneak attack from behind, the two-headed snake's tail looks just like its head. While the business end looks for food, the snake coils up its body and rests its tail on top to look like it is on guard.

The tail can even mimic the behavior of a retreating snake to trick predators into thinking they're going face-to-face with their opponent.

Horoscope: When snakes get down to work, they are organized and highly efficient, and they work quickly and quietly.

In Nature: While snakes are often perceived as lazy, Campbell said people are mistaken. "What we perceive as shy, lazy, or inactive is really efficiency," he said.

"On average, they are bigger than other lizards and can build a lot of body mass. They do that by being efficient in feeding and traveling." In other words, snakes don't move very much because they don't have to.

When it comes to food, snakes catch prey that are significantly larger than them so they can eat less frequently. This reduces the time they spend hunting and thus makes them less vulnerable to falling victim to a predator themselves.

For Campbell, the most impressive hunter is the eastern diamondback rattlesnake (Crotalus Adamanteus), which is able to hunt and kill its prey very quickly using venom, so it doesn't have to travel far. "Because they don't have to do that, they can become relatively large and heavy, being able to build up body mass and not having to spend that energy hunting."

Horoscope: Snakes are charming, with excellent communication skills.

In Nturea: For snakes, their visual and auditory senses don't mean much when it comes to communicating with each other.

Instead, they use their sense of smell and the chemicals produced by their musk glands. Unlike mammals, a snake picks up scent through the forks of its tongue.

When the snake retracts its tongue, it inserts the forks into grooves in an olfactory organ located at the roof of its mouth. Depending on which fork picks up a stronger scent, the snake knows in which direction to go when looking for prey or a mate.

It's when snakes are threatened that they use sight and sound, said Ferraro. Rattlesnakes, for example, shake their tails, making a loud rattling noise to ward off predators.

Vatican Says Pope Benedict Will Resign Feb. 28













Pope Benedict XVI announced today that he will resign Feb. 28, saying his role requires "both strength of mind and body."


The pope's decision makes him the first pontiff to resign in nearly 600 years. A conclave to elect a new pope will take place before the end of March. The 85-year-old pope announced the decision to resign in Latin during a meeting of Vatican cardinals.


VIDEO: Pope Benedict to Resign, Vatican Says


"After having repeatedly examined my conscience before God, I have come to the certainty that my strengths due to an advanced age are no longer suited to an adequate exercise of the Petrine ministry," he said. "I am well aware that this ministry, due to its essential spiritual nature, must be carried out not only by words and deeds but no less with prayer and suffering."


Pope Benedict XVI was the oldest pope to be elected at age 78 on April 19, 2005. He was the first German pope since the 11th century and his reign will rank as one of the shortest in history at seven years, 10 months and three days.


RELATED: Pope Benedict XVI Resigns: The Statement


The last pope to resign was Pope Gregory XII, who stepped down in 1415.


Vatican officials said they've noticed that he had been getting weaker, while Benedict said he is aware of the significance of his decision and made it freely.










Pope Benedict XVI Resignation: Who Will Be Next? Watch Video







Vatican Communications Director Greg Burke told ABC News that he was surprised but wasn't shocked by the announcement, and cited an interview in which Benedict said a pope not only could resign, but should resign.


"[Pope Benedict] is slowing a bit, and there's nothing immediately serious or grave. He has an older brother. He just thought the demands of the job were too much for his physical well being."


Benedict's brother, the Rev. Georg Ratzinger, had shared his concerns about the pope's health in September 2011, telling Germany's Bunte magazine that he should resign if health issues made the work impossible. More recently, Ratzinger has apparently cited his brother's difficulty in walking and his age, saying that Benedict had been advised by his doctor to cease transatlantic trips and that he had been considering stepping down for months, according to the German DPA news agency.


Among other ailments, the pope reportedly suffers from arthritis and arthrosis -- a debilitating joint-degeneration condition -- and his declining health drew attention about a year ago when he used a cane at the airport on his way to a trip to Mexico and Cuba.


Benedict has been a less charismatic leader than his predecessor, John Paul II, but tending to the world's roughly 1 billion Catholics still requires stamina Benedict seems to believe he now lacks.



PHOTOS: Pope Benedict XVI Through the Years


"Obviously, it's a great surprise for the whole church, for everyone in the Vatican and I think for the whole Catholic world," the Rev. John Wauck, a U.S. priest of the Opus Dei, told "Good Morning America" today. "But, at the same time, it's not completely surprising given what the pope had already written about the possibility of resigning.


"It's clear in terms of his mental capacity he's in excellent shape, he's very sharp, and so when he says he's making this official with whole freedom, it's clear that that's the case, that makes one believe that this is an act taken out of a sense of responsibility and love for the church."


It is a road that leads back to the 1930s.


Ratzinger started seminary studies in 1939 at the age of 12. In his memoirs, he wrote of being enrolled in Hitler's Nazi youth movement against his will when he was 14 in 1941, when membership was compulsory. In 1943, he was drafted into a Nazi anti-aircraft unit in Munich. He says he was soon let out because he was a priest in training.


He returned home only to find an army draft notice waiting for him in the fall of 1944.


As World War II came to an end, the 18-year-old Ratzinger deserted the army. In May 1945, U.S. troops arrived in his town and he was sent to a prisoner-of-war camp.

Three Korean doctors slain in north Nigeria: police






KANO, Nigeria: Men armed with knives slit the throats of three South Korean doctors in a pre-dawn attack Sunday in a volatile town in northeastern Nigeria in the latest in a spate of killings of foreigners in recent months, police said.

The attack in Potiskum also came just two days after gunmen killed at least 10 people in horrifying attacks on two Nigerian polio clinics in a new blow to the campaign to wipe out disease, but it was not clear if the incidents were related.

Yobe State police commissioner Sanusi Rufa'i would not say if the Islamist group Boko Haram, which has been active in Potiskum, was responsible for Sunday's killings, but that the attack was being investigated.

He said unknown attackers scaled the fence of an apartment housing the three doctors at around 1:00 am and slit their throats, initially describing the victims as Chinese.

"Further investigations have shown that the victims were Korean nationals and not Chinese as earlier stated. They were doctors from South Korea," Rufa'i told AFP, in comments confirmed by a senior military official in the state.

Residents said the Koreans, whose bodies were found by neighbours, were employees of the state ministry of health and had been living in the city for one year.

In Seoul, the foreign ministry said it was checking the reports, but noted that few Koreans live in the town.

"The chance that the slain would be Koreans is not high," a foreign ministry official told Yonhap news agency. "But we are checking further related situations via diverse channels."

A local resident said the bodies of the Koreans were found in their room by neighbours who alerted security agents,

"People became worried when the doctors did not open their door in the morning," one resident who did not want to be named told AFP.

He said the victims had their throats slit, but it was not immediately clear if the assailants also came with guns.

"It is still premature to point any accusing fingers but we have commenced an investigation to unravel the killings," said Rufa'i, adding: "No arrest has been made."

Sunday's attack was the latest in a spate of killings of foreigners, especially Chinese nationals, in the country's restive northeast.

In November, gunmen shot dead two Chinese construction workers in nearby Borno State, the stronghold of the Boko Haram extremists.

Three other Chinese nationals have also been killed in separate attacks in the region.

Although no group claimed responsibility for the attacks, they were similar to previous strikes against foreigners by Boko Haram.

Violence linked to Boko Haram is believed to have left some 3,000 people dead since 2009, including killings by the security forces.

The killings in Potiskum, which lies about 100 kilometres (60 miles) from the state capital Damaturu, followed attacks on other health workers in the northern city of Kano on Friday.

Nine women and a man were shot dead in two separate attacks in Kano after a local cleric denounced polio vaccination campaigns and some local radio stations aired conspiracy theories about the vaccine being a Western plot to harm Muslims.

Nigerian President Goodluck Jonathan condemned Friday's killings, describing them as "dastardly terrorist attacks" and vowed to track down the perpetrators.

Boko Haram has claimed to be fighting for the creation of an Islamic state, but its demands have shifted repeatedly and it is believed to include various factions. Criminal gangs and imitators are also suspected of carrying out violence under the guise of the group.

Nigeria, Africa's most populous nation and largest oil producer, is divided between a mainly Muslim north and predominantly Christian south.

Andhra CM bats for Telugu in state judiciary

HYDERABAD: Promotion of Telugu in the judiciary would benefit common people in a big way, Andhra Pradesh chief minister N Kiran Kumar Reddy said here on Sunday.

"Increased use of mother tongue in the judicial system would enable the people to understand the proceedings better," Reddy said while speaking at a convention jointly organized by the state official language commission and Andhra Pradesh Judicial Academy on the use of Telugu in judiciary.

He hailed the judiciary for taking a keen interest in enhancing the use of Telugu in courts, an official release said.

Recalling that the state government had recently organised the 4th World Telugu Conference, the chief minister said that the government is taking several steps to promote the language.

Andhra Pradesh high court Chief Justice PC Ghosh, who inaugurated the convention, said one can express himself better in his mother tongue, the release said.

The use of Telugu in judiciary would make it easy for people to understand the proceedings, he said.

AP Judicial Academy chairman Justice N V Ramana said the use of English in judgements made it difficult for rural people to understand them.

Official language commission chairman M Buddha Prasad said the use of Telugu in the judiciary would make it easy for people to understand and also enhance their confidence in the judicial system, the release added.

Paternos Issue Report, Challenge Freeh's Findings













Former FBI director Louis Freeh is standing by his conclusion that former Penn State coach Joe Paterno and three top administrators concealed child sex abuse allegations against Jerry Sandusky.



Freeh responded Sunday to a new critique released by Paterno's family that called Freeh's report last July inaccurate and unfounded, resulting in a "rush to injustice."

Freeh says in a statement he respects the right of the Paterno family to conduct a media campaign in an effort "to shape the legacy of Joe Paterno" but the coach should have done more to stop Sandusky.



Freeh cited grand jury testimony in which Paterno said a graduate assistant relayed to him a 2001 allegation against Sandusky of a "sexual nature" with a child.



He said Paterno's attorney was contacted for an interview with the coach, who died in January 2012.

Horsemeat 'contamination' could date back to August: Findus






LONDON: French frozen food supplier Comigel told the Findus brand that "the contamination" of processed beef products with horsemeat could date back to August 2012, Findus said in a statement Saturday.

"Findus want to be absolutely explicit that they were not aware of any issue of contamination with horsemeat last year," it said in a statement.

"They were only made aware of a possible August 2012 date through a letter dated 2 February 2013 from the supplier Comigel.

"By then Findus was already conducting a full supply chain traceability review and had pro-actively initiated DNA testing."

The opposition Labour lawmaker Tom Watson earlier claimed he had been shown by a retailer a copy of a letter that Findus sent to them on Monday.

He published an extract on his website.

"Investigations have led one of our suppliers based in France to inform us in writing on 2nd February 2013 that the raw materials delivered since 1st August 2012 are likely to be non-conform and consequently the labelling on finished products is incorrect," it said.

Britain's Food Standards Agency regulator announced Thursday that 11 of 18 samples of Findus beef lasagne were found to contain between 60 and 100 per cent horsemeat.

Asked by AFP to comment on Britain's food minister fearing a criminal conspiracy, a Findus spokesman said: "That's part of our investigations. We need to understand how the meat got into the supply chain. That's something we are working on with Comigel, as the supplier."

He did not know how long the investigation would take.

The spokesman said it was "still uncertain... where the meat exactly came from".

"The supplier has asked us to withdraw the raw material batches."

Findus said it was not taking part in the emergency food industry meeting taking place Saturday at the Department for Environment, Food and Rural Affairs.

"Findus did not receive an invitation to this summit. However they are aware that the Food and Drink Federation, of which they are a member, will be attending."

Sweden-based Findus has withdrawn various frozen meals from the market in France and Sweden.

Tihar Jail witnesses hanging after 24 years, Afzal Guru was hanged for eight minutes

NEW DELHI: The Tihar Jail, the largest prison of India, witnessed a hanging on Saturday after 24 years, when the 2001 parliament attack convict Afzal Guru was executed early morning, an official said.

Kehar Singh and Satwant Singh, assassins of then prime minister Indira Gandhi were hanged inside the jail in 1989.

Afzal Guru is the seventh man hanged inside the prison since 1981, a Tihar Jail official told IANS. Guru was hanged at 8am on Saturday.

In 1982, Ranga and Billa were executed for kidnapping and murdering two minors, Geeta Chopra and her younger brother Sanjay.

Maqbool Bhat of the Jammu and Kashmir Liberation Front was executed in 1984 while Jugar Singh was hanged inside the jail in 1985 in the murder case of Vidya Jain.

In 1989, both the assassins of Indira Gandhi were executed by the famous hangman, "Kalu", a resident of Meerut in Uttar Pradesh. He was paid Rs 150 for carrying out the execution process.

'Hanged for 8 minutes'

Guru was hanged at 8am on Saturday in front of eight people in the Tihar Jail in a procedure that took eight minutes, prison sources said.

They told IANS that Guru was informed about his hanging late Friday evening after a death warrant was issued by a Delhi court.

"He was told about his hanging yesterday (Friday) by the jailor," a source said.

The source said Guru was hanged about 20 metres from his cell where he spent 12 years in solitary confinement.

"There were eight people, including a doctor, a magistrate and some jail officials, present when he was hanged. He was hanged for eight minutes," the source told IANS.

Guru was buried quietly soon after the hanging.

After he was woken up at 5am, he offered prayers before calmly approaching the noose, officials said. A Muslim cleric was also present during his hanging.

Guru was convicted for his role in plotting the December 13, 2001, attack on Parliament House, in which 10 people were killed when five armed terrorists stormed into the complex when 100 MPs, then Prime Minister Atal Bihari Vajpayee and his Cabinet ministers were inside.
