Worms frozen for 42,000 years come back to life

Moscow, Jul 29: A sample of microscopic worms that were suspended in a deep freeze in Siberia for 42,000 years have come back to life after being defrosted, scientists say. The findings, published in the journal Doklady Biological Sciences, represent the first evidence of multicellular organisms returning to life after spending a long period in Arctic permafrost.

Nematodes are tiny worms that typically measure about one millimetre in length, and are known to have impressive abilities.

Some are found living 1.3 kilometers below Earth's surface, deeper than any other multicellular animal. Certain worms that live on an island in the Indian Ocean can develop one of five different mouths, depending on what type of food is available.

Researchers from Moscow State University in Russia and Princeton University in the US analysed 300 samples of Arctic permafrost deposits and found two that held several well-preserved nematodes.

One sample was collected from a fossil squirrel burrow near the Alazeya River in the northeastern part of Yakutia, Russia, from deposits estimated to be about 32,000 years old, the 'Live Science' reported. The other permafrost sample came from the Kolyma River in northeastern Siberia, and the age of nearby deposits was around 42,000 years old, scientists said.

The isolated worms represented two known nematode species: Panagrolaimus detritophagus and Plectus parvus. After defrosting the worms, researchers saw them moving and eating, making this the first evidence of "natural cryopreservation" of multicellular animals.

This is not the first organism to awaken from millennia in icy suspension. Previously, another group of scientists had identified a giant virus that was resuscitated after spending 30,000 years frozen in Siberian permafrost.

Facebook on Monday launched a new consumer marketing campaign in India titled 'More Together'. India is the first country in the Asia Pacific region where such a campaign is being rolled out.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

"India is at the heart of Facebook and one of our focus areas this year is to tell the exciting story of a service that is deeply embedded in the fabric of India," said Ajit Mohan, Vice President and Managing Director, Facebook India.

The campaign would have multiple campaigns over the next few weeks in eight languages and the one will be set in the context of Holi.

Facebook in 2019 introduced a new company logo to further distinguish the company from the Facebook app.

The company recently announced the appointment of Avinash Pant as the Marketing Director for India operations, to drive the consumer marketing efforts across the family of apps.

Paris, Jun 16: Increasing numbers of readers are paying for online news around the world even if the level of trust in the media, in general, remains very low, according to a report published Tuesday.

Around 20 percent of Americans questioned said they subscribed to an online news provider (up to four points over the previous year) and 42 percent of Norwegians (up eight points), along with 13 percent of the Dutch (up to three points), compared with 10 percent in France and Germany.

But between a third and a half of all news subscriptions go to just a few major media organisations, such as the New York Times, according to the annual Digital News Report by the Reuters Institute.

Some readers, however, are also beginning to take out more than one subscription, paying for a local or specialist title in addition to a national news source, the study's authors said.

But a large proportion of internet users say nothing could convince them to pay for online news, around 40 percent in the United States and 50 percent in Britain.

YouGov conducted the online surveys of 40 countries for the Reuters Institute in January, with 2,000 respondents in each.

Further surveys were carried out in six countries in April to analyse the initial effects of COVID-19.

The health crisis brought a revival of interest in television news -- with the audience rising five percent on average -- establishing itself as the main source of information along with online media.

Conversely, newspaper circulation was hard-hit by coronavirus lockdown measures.

The survey found trust in the news had fallen to its lowest level since the first report in 2012, with just 38 percent saying they trusted most news most of the time.

However, confidence in the news media varied considerably by country, ranging from 56 percent in Finland and Portugal to 23 percent in France and 21 percent in South Korea.

In Hong Kong, which has been hit by months of sometimes violent street protests against an extradition law, trust in the news fell 16 points to 30 percent over the year.

Chile, which has had regular demonstrations against inequality, saw trust in the media fall 15 percent while in Britain, where society has been polarised by issues such as Brexit, it was down 12 points.

The US space agency has thrown open a challenge to win over Rs 26 lakh, calling the global community to send novel design concepts for compact toilets that can operate in both microgravity and lunar gravity.

NASA is preparing for return to the Moon and innumerable activities to equip, shelter, and otherwise support future astronauts are underway.

The astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity.

NASA said that while astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth.

The public designs for space toilet may be adapted for use in the Artemis lunar landers that take humans back to the Moon.

"Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only," the US space agency said in a statement.

NASA's Human Landing System Programme is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity.

The new NASA challenge includes a Technical category and Junior category and the last date to send designs is August 17.

NASA's Artemis Moon mission will land the first woman and next man on the lunar surface by 2024.

The Artemis programme is part of America's broader Moon to Mars exploration approach, in which astronauts will explore the Moon and experience gained there to enable humanity's next giant leap, sending humans to Mars.
