October 14, 2016: Droplets of glass dug up in New Jersey and from the Atlantic seabed indicate a comet or some other extraterrestrial object may have smacked Earth 56 million years ago, roughly 10 million years after the asteroid impact that doomed the dinosaurs.

Scientists said on Thursday the collision may have triggered a particularly warm, ice-free period on Earth when important mammalian groups, including the primate lineage that led to humans, appeared for the first time.

The findings, published in the journal Science, marked the latest evidence of the profound influence that past impacts by celestial bodies have had on life on Earth.

The tiny spherical bits of dark glass, called microtektites, represent strong evidence of a collision with a comet or asteroid, the researchers said. They form when a space rock hits Earth’s surface and vaporises the spot where it lands, ejecting into the air bits of molten rock that solidify into glass.

The microtektites were excavated from a geological layer marking the start of the Eocene Epoch about 56 million years ago from three sites in southern New Jersey (Millville, Wilson Lake and Medford) and an underwater site east of Florida.

That coincided with the beginning of a warming event, called the Paleocene-Eocene Thermal Maximum, associated with an accumulation of atmospheric carbon dioxide. It lasted more than 100,000 years and drove up global temperatures about 9-14 degrees Fahrenheit (5-8 degrees Celsius).

The impact of an asteroid about six miles wide (10 km) off Mexico’s Yucatan Peninsula 10 million years earlier killed off many marine and terrestrial creatures including the dinosaurs, and enabled mammals to gain supremacy.

No such mass extinction was associated with the event 56 million years ago, although many single-celled ocean-bottom creatures disappeared. During the warming period, primates and two mammal groups — one that includes deer, antelope, sheep and goats and another that includes horses and rhinos — first appear in the fossil record.

The researchers said they have not found the location of an impact crater linked to the collision. They said geological evidence suggested the object was a comet.

“We can’t really say where it was, or how big, at this point,” said geochemist Morgan Schaller of Rensselaer Polytechnic Institute, who led the study.

While the findings are not proof that the impact caused the warming period, they are “a rather dramatic finding in support of an impact trigger” for the climate changes, said planetary scientist Dennis Kent of Columbia University’s Lamont-Doherty Earth Observatory and Rutgers University. (VOA)

June 17, 2018:

Restaurateurs Prodyut and Sumana Mukherjee have not only brought Indian cuisine to the ongoing FIFA World Cup 2018 here but also plan to dish out free dinner to countrymen if Argentina wins the trophy on July 15.

Based in Moscow for the last 27 years, Prodyut and Sumana run two Indian eateries, “Talk Of The Town” and “Fusion Plaza”.

Both restaurants serve popular Indian dishes like butter chicken, kebabs and a varied vegetarian spread.

During the ongoing FIFA World Cup 2018, there will be 25 per cent discount for those who will possess a Fan ID (required to watch World Cup games).

There will also be gifts and contests on offers during matches in both the restaurants to celebrate the event.

The Mukherjees, hailing from Kolkata, are die-hard fans of Argentina. Despite Albiceleste drawing 1-1 with Iceland in their group opener with Lionel Messi failing to sparkle, they believe Jorge Sampaoli’s team can go the distance.

“I am an Argentina fan. I have booked tickets for a quarterfinal match, a semifinal and of course the final. If Argentina goes on to lift

“We have been waiting for this World Cup. Indians come in large numbers during the World Cup and we wanted these eateries to be a melting point,” he added.

According to Cutting Edge Events, FIFA’s official sales agency in India for the 2018 World Cup, India is amongst the top 10 countries in terms of number of match tickets bought.

Prodyut came to Moscow to study engineering and later started working for a pharmaceutical company here before trying his hand in business. Besides running the two restaurants with the help of his wife, he was into the distribution of pharmaceutical products.

“After Russia won the first match of the World Cup, the footfall has gone up considerably. The Indians are also flooding in after the 6-9 p.m. game. That is the time both my restaurants remain full,” Prodyut said.

There are also plans to rope in registered fan clubs of Latin American countries, who will throng the restaurants during matches and then follow it up with after-game parties till the wee hours.

“I did get in touch with some of the fan clubs I had prior idea about. They agreed to come over and celebrate the games at our joints. Those will be gala nights when both eateries will remain open all night for them to enjoy,” Prodyut said.

Watching the World Cup is a dream come true for the couple, Sumana said.

“We want to make the Indians who have come here to witness the spectacle and feel at home too. We always extend a helping hand and since we are from West Bengal, we make special dishes for those who come from Bengal,” she added. (IANS)
