From Archaeology:

A new royal Maya tomb emerges from the tunnels beneath Copán's Acropolis.

The Maya kings of Copán were not interested in moving mountains. They preferred to build their own, like the pyramid now known as Temple 16. Rising 100 feet above the city's Great Plaza, it is the highest point among a group of holy buildings that archaeologists have dubbed "the Acropolis." Inside an excavation tunnel deep beneath the pyramid's surface, the face of the sun-king scowls at me from the wall of his temple. The city's ancient rulers built their temples--one on top of the next--to suit the needs of the moment. The moment I am visiting occurred shortly after A.D. 540 when the first of four temples was built around a small plaza at the top of the Acropolis.

Monster Supernovae May Explain Galaxy's Mystery Haze

The mysterious WMAP haze (Image: WMAP)

From New Scientist:

WHAT is causing a mysterious "haze" of radiation at the centre of the Milky Way? It may be a load of monster supernovae kicking out radiation which is then amplified by magnetic stellar winds and turbulence near the galaxy's core.

In 2003, the Wilkinson Microwave Anisotropy Probe found a patch of particularly energetic microwave radiation in the centre of our galaxy - dubbed the "WMAP haze". It was proposed that this could be caused by collisions of a new type of dark-matter particle.

Warning Over 'Monster' 20ft Great White Shark Which Bit Another Great White In Half

We're going to need a bigger boat: The remains of a 14ft great white shark that was bitten nearly in half by what authorities - judging from the size of the bite marks - estimated was a 20ft monster

From The Daily Mail:

A 'monster' great white shark measuring up to 20 ft long is on the prowl off a popular Queensland beach, according to officials.

Swimmers were warned to stay out of the water off Stradbroke Island after the shark mauled another smaller great white which had been hooked on a baited drum line.

The 10-foot great white was almost bitten in half.

The fictional shark at the centre of the Steven Spielberg blockbuster Jaws was estimated to be just five feet longer.

From Science Daily:

Science Daily (Oct. 27, 2009) — Alcohol consumption has long been linked to cancer and its spread, but the underlying mechanism has never been clear. Now, researchers at Rush University Medical Center have identified a cellular pathway that may explain the link.

In a study published in a recent issue of Alcoholism: Clinical and Experimental Research, the researchers found that alcohol stimulates what is called the epithelial-to-mesenchymal transition, in which run-of-the-mill cancer cells morph into a more aggressive form and begin to spread throughout the body.

Why 'Sleeping On It' Helps

From Live Science:

We're often told, "You should sleep on it" before you make an important decision. Why is that? How does "sleeping on it" help your decision-making process?

Conventional wisdom suggests that by "sleeping on it," we clear our minds and relieve ourselves of the immediacy (and accompanying stress) of making a decision. Sleep also helps organize our memories, process the information of the day, and solve problems. Such wisdom also suggests that conscious deliberation helps decision making in general. But new research (Dijksterhuis et al., 2009) suggests something else might also be at work — our unconscious.

Awesome Pictures Of Saturn

From 20 degrees above the ring plane, Cassini's wide angle camera shot 75 exposures in succession for this mosaic showing Saturn, its rings, and a few of its moons a day and a half after exact Saturn equinox, when the sun's disk was exactly overhead at the planet's equator. The images were taken on Aug. 12, 2009, at a distance of approximately 847,000 km (526,000 mi) from Saturn. (NASA/JPL/Space Science Institute)

Saturn At Equinox -- Boston.com

Checking in with NASA's Cassini spacecraft, our current emissary to Saturn, some 1.5 billion kilometers (932 million miles) distant from Earth, we find it recently gathering images of the Saturnian system at equinox. During the equinox, the sunlight casts long shadows across Saturn's rings, highlighting previously known phenomena and revealing a few never-before seen images. Cassini continues to orbit Saturn, part of its extended Equinox Mission, funded through through September 2010. A proposal for a further extension is under consideration, one that would keep Cassini in orbit until 2017, ending with a spectacular series of orbits inside the rings followed by a suicide plunge into Saturn on Sept. 15, 2017.

From New Scientist:

EVERY two weeks, the sun pours more energy onto the surface of our planet than we use from all sources in an entire year. It is an inexhaustible powerhouse that has remained largely untapped for human energy needs. That may soon change in a big way. If a consortium of German companies has its way, construction of the biggest solar project ever devised could soon begin in the Sahara desert. When completed, it would harvest energy from the sun shining over Africa and transform it into clean, green electricity for delivery to European homes and businesses.
