UCLA scientist discovers plate tectonics on Mars

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars.

"Mars is at a primitive stage of plate tectonics. It gives us a glimpse of how the early Earth may have looked and may help us understand how plate tectonics began on Earth," said An Yin, a UCLA professor of Earth and space sciences and the sole author of the new research.

Startups and the Singularity: Which Boston Innovators Are Believers?

Hollywood has Scientology. The tech world has the Singularity. I’m not conflating their beliefs or intellectual frameworks. I’m not calling them cults. I’m just saying, either you believe it or you don’t.

As it would happen, I was sitting around a table at a local startup shooting the breeze about what’s on entrepreneurs’ minds these days. The guys from Boundless, an ed-tech company that just opened its site to the masses this week, said there have been numerous lunchtime debates about something called the Singularity. My first reaction was that these guys have been working way too hard.

Zapotec Digs in Mexico Show Clues to Rise and Fall

When it comes to pre-Columbian civilizations, the Aztec and Maya—known for their spectacular pyramids and temples, hieroglyphic writing systems, and elaborate, violent rituals—often overshadow the Zapotec, their less familiar counterparts centered in southern Mexico.

But the Zapotec also played a vital role in ancient Mesoamerica, and archaeologists are seeking new clues to the rise and fall of their culture and civilization, which flourished and declined in the Valley of Oaxaca at roughly the same time as the ancient Maya.

Veni odată un prieten şi-i ceru împrumut o sumă. El bani n-avea, dar îi porunci unui rob din casa să pună apă într-un pahar de argint şi să i-l aducă, îi aduse robul apa şi dânsul îşi săpuni barba ca şi cum ar fi vrut să se radă.îi făcu drum apoirobului din odaie după altă treabă şi-i dădu paharul prietenului zicându-i să facă ce-o vrea cu el. Văzu însă că se face multă zarvă în casă pentru paharul acela şică nevasta sa, mânioasă, e gata să pună la cazne robii, îi mărturisi fapta si-o rugă să-lierte.

Thucydides in London: Would the Ancient Greeks Approve of Our Modern Olympics?

The precious heritage of ancient Greece: The recognition that a life without excitement is a life scarcely worth living and that a life of excitement must inevitably be a life full of risks.

As I was watching the London Olympics, a curious thought struck me: What would the ancient Greeks think about our modern revival of their games? Would they be impressed, scandalized, or just disappointed?
