Growing old gracefully! Maria Shriver shows Kris Jenner how it should be done as she attends her low-key 60th birthday bash
Her fellow celebrity matriarch Kris Jenner was marking the start of her seventh decade with an over-the-top Great Gatsby themed bash.
But classy Maria Shriver showed her rival how it should be done when she attended her low-key 60th birthday celebration in Bel Air on Friday.
The chic television journalist and former First Lady Of California wore a warm smile as she acknowledge her fans before heading inside to crack open a bottle of bubbly and blow out her candles in the posh area of Los Angeles.
For those of you who sat through Monday Night Football just to catch the new Star Wars: The Force Awakens trailer, you were rewarded handsomely with a foreshadowing of what some are claiming could be the best episode ever, byLost’s J.J. Abrams. The elements are certainly there, from familiar faces like Han Solo and Princess Leia to a dessicated Darth Vader to an epic Millennium Falcon chase and a bunch of brand-new droid characters.
Watch it above for yourself, and begin the countdown to Dec. 18.
Living organisms may have existed on Earth as long as 4.1bn years ago – 300m years earlier than was previously thought, new research has shown.
If confirmed, the discovery means life emerged a remarkably short time after the Earth was formed from a primordial disc of dust and gas surrounding the sun 4.6bn years ago.
Researchers discovered the evidence in specks of graphite trapped within immensely old zircon crystals from Jack Hills, Western Australia.
Atoms in the graphite, a crystalline form of carbon, bore the hallmark of biological origin. They were enriched with 12C, a “light” carbon isotope, or atomic strain, normally associated with living things.
It suggests that a terrestrial biosphere had emerged on Earth as early as 4.1bn years ago, said the scientists writing in the journal Proceedings of the National Academy of Sciences.
The US scientists, led by Dr Mark Harrison, from the University of California at Los Angeles, said the graphite was completely encased in zircon that was crack-free and could not have been contaminated despite the passing of aeons.
They wrote: “This study extends the terrestrial carbon isotope record around 300m years beyond the previously oldest-measured samples from south-west Greenland.”
Some non-biological processes could also produce the light form of carbon, notably meteorite impacts, said the researchers.
But the amount of extra-terrestrial carbon needed to account for the findings made meteorites an unlikely source.
“A biogenic origin seems at least as plausible,” the scientists added.
Confirming the connection with early life would represent “a potentially transformational scientific advance” they said.
