Titanic wreck deteriorating at pace faster than expected

Washington D.C, Aug 23: The Royal Merchant Ship Titanic is now in the process of being swallowed up by metal-eating bacteria in the sea, divers found when they visited the site for the first time in 14 years. 

The ship which was deemed "unsinkable" was inspected five times in August by an exploration team from Triton Submarines to the spot 370 miles south of Newfoundland, Canada, and 4,000 meters below the surface, said a release from Triton, a civil submarine producer. 

The divers of the project will be publishing the full results alongside a documentary film being made by Atlantic Productions London.

The footage of the 107-year-old wreck was captured through specially adapted cameras which were being handled by a team of experts, scientists and a National Ocean and Atmospheric Administration.

Interestingly, the 4K video will make it possible to watch the wreck in augmented and virtual reality technology.

The luxury ship sank in the year 1912 after hitting an iceberg, leading to the deaths of 1,517 of the 2,223 people on board.

The video showed the impact that salt corrosion, metal-eating bacteria, and the deep current action is having on Titanic.

"The most fascinating aspect was seeing how the Titanic is being consumed by the ocean and returning to its elemental form while providing refuge for a remarkably diverse number of animals," said Patrick Lahey, the president and co-founder of Triton Submarines.

Victor Vescovo, CEO of Caladan Oceanic and the submersible's chief pilot, noted that the achievement of this series of dives to the Titanic has opened doors to reach other difficult to visit wrecks using a similar process.

"We now have a proven system that can easily and repeatedly visit an ocean wreck, at any depth, anywhere in the world, and study it in detail. We're seriously thinking about where to take her next," Vescovo said.

Kanpur, Jul 11: "The Uttar Pradesh administration has done the right thing by taking action against my son," said an old and feeble Ram Kumar Dubey, father of gangster Vikas Dubey.

The father said his son killed eight police officials and it was an unforgivable sin.

"Had he listened to us, his life would not have ended this way. Vikas never helped us in any way. Due to him, even our ancestral property was razed to the ground. He also killed eight policemen, which is an unforgivable sin. The administration has done the right thing. Had they not done so, tomorrow others would have acted similarly," Ram Kumar said.

"It is the chief minister's duty to protect every individual. The police is an extension of that. He attacked them which cannot be forgiven. I will not even take part in his cremation," he added.

Ram Kumar Dubey said that his only appeal to the government is to allow him entry to his ancestral property now.

Vikas Dubey was cremated at Bhairav Ghat in Kanpur. His wife, younger son and brother-in-law were present and no other member of his family attended the last rites.

Vikas Dubey was arrested by the police in Ujjain on Thursday morning. He was on the run for the last six days and had come to the city to offer prayers at a temple, where he was identified by a security guard.

He was killed in an encounter by the Uttar Pradesh Police earlier today after he "attempted to flee".

The gangster was the main accused in the encounter that took place in Bikru village in Chaubeypur area of Kanpur last week, in which a group of assailants opened fire on a police team, which had gone to arrest him.

Eight police personnel were killed in the encounter.

Vikas Dubey managed to escape after the incident. Uttar Pradesh police had launched a hunt and raised a bounty on him for Rs 5 lakh.

Washington DC, Jun 8: Astronomers acting on a hunch have likely resolved a mystery about young, still-forming stars and regions rich in organic molecules closely surrounding some of them.

They used the National Science Foundation's Karl G Jansky Very Large Array (VLA) to reveal one such region that previously had eluded detection and that revelation answered a longstanding question.

The regions around the young protostars contain complex organic molecules which can further combine into prebiotic molecules that are the first steps on the road to life.

The regions, dubbed "hot corinos" by astronomers, are typically about the size of our solar system and are much warmer than their surroundings, though still quite cold by terrestrial standards.

The first hot corino was discovered in 2003 and only about a dozen have been found so far. Most of these are in binary systems, with two protostars forming simultaneously.

Astronomers have been puzzled by the fact that, in some of these binary systems, they found evidence for a hot corino around one of the protostars but not the other.

"Since the two stars are forming from the same molecular cloud and at the same time, it seemed strange that one would be surrounded by a dense region of complex organic molecules and the other wouldn't," said Cecilia Ceccarelli, of the Institute for Planetary Sciences and Astrophysics at the University of Grenoble (IPAG) in France.

The complex organic molecules were found by detecting specific radio frequencies, called spectral lines, emitted by the molecules. Those characteristic radio frequencies serve as "fingerprints" to identify the chemicals.

The astronomers noted that all the chemicals found in hot corinos had been found by detecting these "fingerprints" at radio frequencies corresponding to wavelengths of only a few millimetres.

"We know that dust blocks those wavelengths, so we decided to look for evidence of these chemicals at longer wavelengths that can easily pass through dust," said Claire Chandler of the National Radio Astronomy Observatory, and principal investigator on the project.

"It struck us that dust might be what was preventing us from detecting the molecules in one of the twin protostars," added Chandler.

The astronomers used the VLA to observe a pair of protostars called IRAS 4A, in a star-forming region about 1,000 light-years from Earth. They observed the pair at wavelengths of centimetres.

At those wavelengths, they sought radio emissions from methanol, CH3OH (wood alcohol, not for drinking). This was a pair in which one protostar clearly had a hot corino and the other did not, as seen using the much shorter wavelengths.

The result confirmed their hunch. "With the VLA, both protostars showed strong evidence of methanol surrounding them. This means that both protostars have hot corinos. The reason we did not see the one at shorter wavelengths was because of dust," said Marta de Simone, a graduate student at IPAG who led the data analysis for this object.

The astronomers cautioned that while both hot corinos now are known to contain methanol, there still may be some chemical differences between them. That, they said, can be settled by looking for other molecules at wavelengths not obscured by dust.

"This result tells us that using centimetre radio wavelengths is necessary to properly study hot corinos," Claudio Codella of Arcetri Astrophysical Observatory in Florence, Italy, said.

"In the future, planned new telescopes such as the next-generation VLA and SKA, will be very important to understanding these objects," added Codella.

New Delhi, Jan 2: Thirteen firefighters were among the 14 people injured when a battery factory collapsed in northwest Delhi's Peera Garhi following an explosion due to a fire that broke out early on Thursday morning, officials said.

A fire brigade personnel still remained trapped under the debris of the building in Udyog Nagar area, an official said.

A large portion of the two-storey building collapsed following an explosion when firefighters were dousing the blaze, the official said, adding that fire department had received a call at 4.23am.

Plumes of smoke billowed out from the building as the fire brigade personnel battled to contain the blaze. An eyewitness said several explosions were heard as the blaze gutted down the building.

The National Disaster Response Force (NDRF) and civil authorities rushed to the spot to control the situation, an official said, adding that 35 fire tenders were at the spot.

The injured, including a security guard of the factory, were rushed to nearby hospitals, a police officer said.

Chief Minister Arvind Kejriwal said he was monitoring the situation.

"V sad to hear this. Am closely monitoring the situation. Fire personnel trying their best. Praying for the safety of those trapped," Kejriwal tweeted.
