Canada, September 29, 2017 : Rocky outcrops in eastern Canada contain what may be some of the oldest evidence of life on Earth, dating back about 3.95 billion years.

Scientists said on September 27 that they found earliest indirect evidence of life on Earth in the form of bits of graphite contained in sedimentary rocks from northern Labrador that they believe are remnants of primordial marine microorganisms.


The researchers carried out a geological analysis of the Labrador rocks and measured concentrations and isotope compositions of the graphite, and concluded that it was produced by a living organism.

They did not find fossils of the microorganisms that may have left behind the graphite, a form of carbon, but said they may have been bacteria.

“The organisms inhabited an open ocean,” said University of Tokyo geologist Tsuyoshi Komiya, who led the study published in the journal Science.

Earth formed about 4.5 billion years ago and the oceans appeared roughly 4.4 billion years ago. The new study and some other recent research indicate that microbial life emerged earlier than previously known and relatively soon after the Earth’s formation.

Canada has produced some of the most ancient signs of life on Earth.

Another team of scientists in March reported that microfossils between 3.77 billion and 4.28 billion years old found in northern Quebec, relatively close to the Labrador site, are similar to the bacteria that thrive today around sea floor hydrothermal vents.

Other scientists last year described 3.7 billion-year-old fossilized microbial mats, called stromatolites, from Greenland. (VOA)

The world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

Heinz has just rolled out a new product that the condiment company says is the "biggest innovation in sauce since the packet itself." Earlier this month, the world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

"Do not click 'purchase' unless you are prepared to change everything about the way you sauce," the Heinz Packet Roller website says. The roller goes for $5.70. The roller is pocket-sized, can be added to a keychain, and features a packet corner cutter.

Swiss tennis ace Roger Federer, is recovering from a right-knee surgery he underwent last month.

Swiss tennis ace Roger Federer, who is recovering from a right-knee surgery he underwent last month, said on Sunday that it was a difficult process to decide whether to undergo a third right-knee surgery after having two last year. But following Wimbledon, where he was "really unhappy" with his performance in reaching the quarterfinals, Federer opted to go through with it.

Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year". "The reception I've received, everybody is so upbeat that I'm here. They wish me all the best and they don't even see the crutches. They just want me to be good again and enjoy the weekend," Federer said in an interview for the event with former world No. 1 Jim Courier.

"I've seen some incredible tennis, some great matches and it's been wonderful. I'm really happy I made the trip," the winner of 20 majors was quoted as saying by atptour.com. On why he opted for a third surgery, the tennis ace said, "I was just nowhere near where I wanted to be to play at the top, top level. But I tried my best and at the end... too much is too much. Now I've just got to take it step by step," Federer said.

Cleopatra, was regarded as a great beauty, to preserve her skin, she took her daily bath in donkey milk.

So, it's no secret that donkey milk is a powerhouse of nutrients for both the skin and body.

Used for Anti-Ageing and Healing
The milk contains essential fatty acids that work as powerful anti-ageing and healing properties. These fatty acids blur the wrinkles on the skin and help to regenerate damaged skin. Plus, donkey milk also contains anti-bacterial properties which are effective in healing skin irritation and redness.
