This cluster of cells is one example of the spheroidal and ellipsoidal microfossils found at the 3.4-billion-year-old.
Scientists say life thrived on Earth 3.4 billion years ago even though the world still had no oxygen. But now they say they have the world’s oldest fossils to prove it.

Hewlett-Packard announced this week that it is exploring jettisoning its struggling PC business in favor of investing more heavily in software, where it sees better potential for growth. Google plans to buy up the cellphone handset maker Motorola Mobility. Hewlett-Packard and Google’s moves surprised the tech world. Marc Andreessen (board member at Hewlett-Parckard) explains why software is eating the world.
By tapping into Albert Einstein’s idea of “spooky action at a distance,” researchers at the University of Copenhagen’s Niels Bohr Institute have discovered what might be the key to completely secure data transfer — keeping particles “entangled” for up to an hour…
The explosive growth of cities worldwide over the next two decades poses significant risks to people and the global environment, according to a meta-analysis published August 19 in PLoS ONE.
Researchers from Yale, Arizona State, Texas A&M and Stanford predict that by 2030 urban areas will expand by 590,000 square miles — nearly the size of Mongolia — to accommodate the needs of 1.47 billion more people living in urban areas…
Futurist Thomas Frey: Many dental offices today use a device called an intraoral camera to show patients why they need a root canal. With little more than a camera on the end of a lighted wand, the technology gives people a new insider perspective into one of the least observed, yet most used, parts of the human body – the mouth.

Since 1999 outstanding student loan debt has grown by more than 511 percent.
“I still have student loans,” David Guard, a graduate of Gettysburg College and American University, told Fox News recently, as lawmakers and the White House bickered over the debt ceiling. “I could see an increase in those interest rates.”
Single men could die about a decade earlier than married men. Single women don’t fare much better.
Being single is great, isn’t it? You get to sleep on either side of the bed; you never have to wait for the bathroom; you’ve got all that “me time.” Except, well, you may be one of the unlucky singles who keel over about one decade earlier than your married friends, according to a new study published in the American Journal of Epidemiology.
Boys are maturing physically earlier than ever before. The age of sexual maturity has been decreasing by about 2.5 months each decade at least since the middle of the 18th century. Joshua Goldstein, director of the Max Planck Institute for Demographic Research in Rostock (MPIDR), has used mortality data to demonstrate this trend, which until now was difficult to decipher. What had already been established for girls now seems to also be true for boys: the time period during which young people are sexually mature but socially not yet considered adults is expanding…
Would you believe this could be the new look of solar power?
7th grader Aidan Dwyer was walking in the woods during the winter, and looking up, he noticed something about the bare branches above him. They didn’t appear to be growing randomly. So he took some measurements of the angles of the branches, crunched some numbers, and wouldn’t you know it, he found that the ubiquitous Fibonacci Sequence was behind it all. He suspected there was a reason behind this. That trees were using this pattern to gather more light.
So he did an experiment. Using the same number of solar cells, he built two working models. One was a traditional, flat array will all of the panels on a single plane. The other used the Fibonacci Sequence to create the same spiraled pattern he observed in the trees. The results? The little man himself reports…
