From the page: "A death toll in the tens of thousands was feared last night after a powerful earthquake flattened schools and homes in densely populated areas of southwestern China.
"The quake, with a magnitude of 7.8 on the Richter scale, struck just before 2.30pm ... about 92 km from Chengdu, a city of more than 12 million people."
I've been to this region and the slopes are very sttep, making landslides very likely. See oak.ucc.nau.edu/wittke/Tibet/Longmen.html [oak.ucc.nau.edu/wittke/Tibet/Longmen.html] .

From the page: "The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet, say scientists from the U.S., U.K., Italy, and New Zealand in this month's Geology.
"The beads, known to geologists as carbon cenospheres, cannot be formed through the combustion of plant matter, contradicting a hypothesis that the cenospheres are the charred remains of an Earth on fire. If confirmed, the discovery suggests environmental circumstances accompanying the 65-million-year-old extinction event were slightly less dramatic than previously thought."

From the page: "Emotional memories of traumatic life events such as accidents, war experiences or serious illnesses are stored in a particularly robust way by the brain. This renders effective treatment very difficult. Researchers at ETH Zurich and the University of Zurich have now successfully tracked down the molecular bases of these strong, very persistent memories."

From the page: "Hydrogen bonds are quite small, on the level of a few angstroms. They can also be passed between two different molecules very quickly, at speeds of tens of times per second. But in spite of these properties, researchers have recently observed hydrogen-bond exchange taking place in real-time."
(right) Image of the H20 and D20 dimers. The H20 dimer appears to fluctuate in the image because they exchange hydrogen bonds 60 times faster than the D20 dimers. The rate difference implies that the interchange proceeds via quantum tunneling. Credit: Kumagai, et al.

From the page: "New scientific evidence suggests that deep inside the planet Mercury, iron "snow" forms and falls toward the center of the planet, much like snowflakes form in Earth's atmosphere and fall to the ground."

From the page: "After 9,000 years of silence, Chile's Chaiten volcano (pictured on May 3) is erupting with lava, ash and lightning.
"Since the volcano awoke on May 2, it has continued erupting intermittently, blanketing the area in ash and forcing more than 4,000 people to flee."

From the page: "People who sleep less than six hours a night -- or more than nine -- are more likely to be obese, according to a new study that is one of the largest to show a link between irregular sleep and big bellies.
"The study also linked light sleepers to more smoking, less physical activity and more alcohol use."
