making factories within cells the royal swedish academy of sciences said americans venkatraman ramakrishnan thomas steitz and israeli ada yonath work on ribosomes has been fundamental to the scientific understanding of life and has helped researchers develop antibiotics yonath is the fourth woman to win the nobel chemistry prize and the first since when dorothy crowfoot hodgkin of britain received the award i am really really happy yonath said i thought it was wonderful when the discovery came it was a series of discoveries we still do not know every everything but we progressed a lot this year three laureates who will share the million kronor million award generated three dimensional models that show how different antibiotics bind to ribosomes these models are now used by scientists in order to develop new antibiotics directly assisting the saving of lives and decreasing humanity suffering the academy said in its announcement they used a method called x-ray crystallography to pinpoint the positions of the hundreds of thousands of atoms that make up the ribosome this knowledge can be put to a practical and immediate use many of today antibiotics cure various diseases by blocking the function of bacterial ribosomes the citation said without functional ribosomes bacteria cannot survive this is why ribosomes are such an important target for new antibiotics building on darwin theory their work builds on charles darwin theory of evolution and more directly on the work done by james watson francis crick and maurice wilkins who won the nobel prize in medicine for mapping dna double helix the citation said in roger d kornberg won the nobel prize in chemistry for x-ray structures that showed how information is copied to messenger rna molecules which carry information from dna to the ribosomes now one of the last pieces of the puzzles has been added understanding how proteins are made said professor gunnar von heijne of the swedish academy of sciences the chairman of the nobel committee for chemistry this discovery is important not only for science as such but also gives us tools to develop new antibiotics ramakrishnan who was born in chidambaram tamil nadu india is the senior scientist and group leader at the structural studies division of the mrc laboratory of molecular biology in cambridge england ramakrishnan said that he was not convinced when he got the morning phone call from the academy well you know i thought it was an elaborate joke i have friends who play practical jokes ramakrishnan told the associated press by telephone from his lab in cambridge i complimented him on his swedish accent steitz a year old born in milwaukee is a professor of molecular biophysics and biochemistry at yale university and attached to the howard hughes medical institute yonath is a professor of structural biology at the weizmann institute of science in rehovot israel and the ninth israeli to win a nobel prize she told israel radio she did not think her gender played a role in the decision it true that a woman has not won since but i do not know what that means does it mean that i am the best woman since then i do not think that gender played a role here she said she had to end the interview abruptly because israeli president shimon peres a nobel peace prize laureate was on the other line alfred nobel a swedish industrialist who invented dynamite established the nobel prizes in his will in the first awards were handed out six years later each prize comes with a million kronor million purse a diploma a gold medal and an invitation to the prize ceremony in stockholm on dec the peace prize is handed out in oslo on monday three american scientists shared the nobel prize in medicine for discovering a key mechanism in the genetic operations of cells an insight that has inspired new lines of research into cancer the physics prize on tuesday was split between a hong kong based scientist who helped develop fibre optic cable and two canadian and american researchers who invented the eye in digital cameras technology that has revolutionised communications and science the literature and peace prize winners will be announced later this week and the economics announcement is set for monday talking tough a day after the beheading of a jharkhand police officer home minister p chidambaram on wednesday said the security forces would engage the maoists till they abjured violence and the indian air force would take steps to protect itself against any naxal attack as long as the cpi maoist believes in an armed liberation struggle we have no option but to ask our security forces to engage them we will arrest them we will apprehend them he told a press conference here not a war he said the government did not consider the naxalite confrontation as a war we do not wage a war against our own people what we said was that the naxalite or cpi maoist must abjure violence and take the path of democracy and dialogue he said counter measures asked about the iaf seeking permission to fight back if the naxals fire upon its helicopters and crew operating in maoist hit areas the home minister said the iaf would take adequate counter measures however the home minister refused to reveal any details mr chidambaram said an indian air force helicopter was fired at by the maoists a few weeks back in chhattisgarh permission sought air chief marshal pv naik had said the iaf had sought permission from the defence ministry to open fire in self defence if its helicopters or air crew operating in the maoist infested areas came under attack union home minister p chidambaram said on wednesday that the government was ready to hold a dialogue with naxals or supporters of the communist party of india maoist provided they abjure violence they maoists use words like war and war of liberation we do not regard our confrontation with them as war we do not wage war against our own people he said maoists should take the path of democracy we will help the state governments discuss with the maoists all the issues of neglect corruption development etc but no development is possible with violence no democracy can accept the theory of an armed rebellion they should first abjure violence award for rukhsana he commended the jammu and kashmir police for doing a good job in the ongoing encounters with militants the j k police are set to become the frontline security force in the country mr chidambaram said he also hailed the heroism of rukhsana kaur who gunned down militants in her house the government had recommended her for a bravery award and she would receive it in due time he dismissed reports of taliban militants being inducted in j k as speculative and baseless on the banned organisation students islamic movement of india simi the minister said it was trying to metamorphose into new organisations under different names we are aware that one or two organisations are being floated by ex-simi cadres);
