LAURA KNIGHT-JADCZYK AND JOE QUINN
Since the 9/11 attacks, no book has provided a satisfactory answer as to WHY the attacks occurred and who was ultimately responsible for carrying them out - until now.
Science & Technology
IT'S the year 250,000,000 and Earth is alive and well. Humans have long since perished, but the planet is still home to a bewildering array of life forms. Yet apart from a few mysterious fossils there is no trace that we ever existed.
A century after the first electric washing machines promised to take the work out of laundry, it doesn't seem like today's multi-cycle magicians are saving us much time.
Sure we don't have to boil the water and lug it by hand over to big metal tubs. Nor do we have to strain our arms running sopping wet clothes through a wringer thanks the advent of the spin cycle.
But, somehow, the pile of washing has managed to grow ever larger with every seemingly time-saving advance.

According to Next Energy News, work funded by the U.S. Air Force Research Laboratory may produce batteries capable of fueling an electrical device, like a laptop, for about 30 years.
The breakthrough betavoltaic power cells are an alternative energy technology, similar to that of a solar panel, which converts photons (light) into electric current. The betavoltaic batteries are constructed from semiconductors that use radioisotopes as the energy source. As the radioactive material decays, it emits beta particles that transform into usable electric power.

The world's tiniest radio is a step closer to reality.
Super trees that suck up and destroy toxic chemicals from the air and water faster than regular trees are the latest creation by scientists at the University of Washington.
When the scientists stick a rabbit gene into poplar trees, the trees become dramatically better at eliminating a dozen kinds of pollutants commonly found on poisoned properties.

To better understand global warming -- and the role of largely man-made changes that began with the Industrial Age two centuries ago and are now galloping at breakneck speed -- scientists aboard the CCGS Amundsen hunt for clues in the mud and bedrock, peat moss and plankton and permafrost. Using sonars and CAT scans, radioactive isotopes like carbon 14 and other indelible markers, they seek to chart and date everything from where the seawater came from, and when, to how long sediment layers have rested undisturbed on the sea floor.
NACHVAK FJORD, Labrador -- Beneath their sheaths of ice and permafrost, those blustery islands at the top of the world hide souvenirs of a distant tropical past. Remnants of fossil forests are strewn across the ridges of Ellesmere and Axel Heiberg in Canada's High Arctic. In Norway's Svalbard archipelago, the rocky cliffs of Spitsbergen are embedded with coral shells, relics from centuries spent somewhere south of modern-day Fort Lauderdale.

Neanderthals, often portrayed as grunting, club-carrying brutes, may have been capable of sophisticated speech, researchers said on Thursday.
For early humans, one of the first displays of modern behavior was a sort of beach party and clam bake along the coast of South Africa.

Using a little-known Google Labs widget, computer scientists from UC San Diego and UCLA have brought common sense to an automated image labeling system. This common sense is the ability to use context to help identify objects in photographs.
Apple Inc said on Tuesday the newest version of its Macintosh operating system would go on sale on October 26, hitting the market after a four-month delay due to the company's work on the iPhone.
