Science Glance
In a building at NASA’s Ames Research Center here, computers are sifting and resifting the light from 156,000 stars, seeking to find in the flickering of distant suns the first hints that humanity is not alone in the universe. The stars are being monitored by a $600 million satellite observatory named Kepler, whose job is to conduct a kind of Gallup poll of worlds in the cosmos.
On Wednesday, Kepler’s astronomers are scheduled to unveil a closely kept list of 400 stars that are their brightest and best bets so far for harboring planets, some of which could turn out to be the smallest and most Earth-like worlds discovered out there to date. They represent the first glimpse of riches to come in a quest that is as old as the imagination and as new as the iPad.
The discovery of an ancient stone tool kit in the United Arab Emirates, reported in today's edition of the journal Science, now is raising the possibility that today's modern humans first started leaving Africa earlier than paleontologists previously thought.
The Hubble Space Telescope has detected what scientists believe may be the oldest galaxy ever observed. It is thought the galaxy is more than 13 billion years old and existed 480 million years after the Big Bang.
In the wake of the shootings in Tucson, the familiar questions inevitably resurfaced: Are communities where more people carry guns safer or less safe? Does the availability of high-capacity magazines increase deaths? Do more rigorous background checks make a difference?
When is a kilogram not a kilogram? When it starts to weigh less. It came into existence more than two centuries ago and has become the standard unit of weight around the world, from the shopping malls of Europe to the souks of the Middle East, but scientists believe that the reign of the kilo as we know it is about to come to an end.
The very reputation of so-called "science" has been irreparably damaged by the invocation of the term "science" by GMO lackeys, pesticide pushers, mercury advocates and fluoride poisoners who all claim to have science on their side. It seems that every toxin, contamination and chemical disaster that now infects our planet has been evangelized in the name of "science."
It's the ultimate experience for Star Wars fans - staring forlornly off into the distance as twin suns sink into the horizon. Yet it's not just a figment of George Lucas's imagination - twin suns are real. And here's the big news - they could be coming to Earth.
