At least four earthquakes with a magnitude of about 6.0 on the Richter scale shook the East China Sea early Friday.
High temperatures can reverse the sex of dragon lizards before they hatch, turning males into females.
The finding, detailed in the April 20 issue of the journal Science, could have implications for the development of life as the planet's climate warms.
The research reveals that extreme temperatures could inactivate a gene on the male sex chromosomes of dragon lizards and thus turn male embryos into females. The sex-reversed lizards look female and have female organs but genetically they are male, said lead author Alexander Quinn of the University of Canberra in Australia.

When conservation officer Steve Peterson got a call that a timber wolf was chasing vehicles on a country road near Brimson, he thought it was prank or a misidentified German shepherd. But then he saw it firsthand.
"I couldn't believe it. It was like a dog chasing cars,'' Peterson said. "It looked like a big, healthy male wolf. No mange.''
Responding to the call last Friday, Peterson saw the animal hide in the ditch as a pickup approached and then come bounding out to chase it.
The wolf did the same when Peterson drove to that spot, where he stopped his vehicle.

NEIVA, Colombia - Thousands of people were evacuated after a long-dormant volcano erupted late Tuesday and again early Wednesday, provoking avalanches and floods that swept away houses and bridges.
The storm that walloped the Northeast on Monday, April 16, was the culmination of a five-day weather event and left behind significant conditions.

On the 101 anniversary of the San Francisco Earthquake, a 4.8 quake shook the Lake Pillsbury area in northern California, about 150 miles north of San Francisco.
LHASA - China has succeeded in creating artificial snow in the northern part of the Tibet Autonomous Region for the first time, according to the local meteorological department.
Taking advantage of suitable weather conditions, the Tibet meteorological station carried out an artificial snowfall operation in Nagqu County in northern Tibet on April 10 at an altitude of about 4.500 meters.

Following the second warmest winter on record two natural events suggest we have leapfrogged spring and moved straight to summer, a conservation charity said today.
Following a weekend where some parts of the UK basked in temperatures 10C above the seasonal average, the Woodland Trust said flowering hawthorn and the return of migrating swifts indicated that summer had arrived a month earlier than usual this year.

Forces brewing deep beneath Yellowstone National Park could be making one of the largest volcanoes on Earth even bigger, a new study reveals.
In the past decade, part of the volcano has risen nearly five inches, most likely due to a backup of flowing molten rock miles below the planet's crust.
While the rise may not be noticeable to the casual hiker, the activity may have cracked the crust in the park's famous Norris Geyser Basin (NGB), leading to the formation of new fumaroles-holes that vent smoke and gas-and the reawakening of some of the area's geysers, including Steamboat, the largest geyser in the world.
Yellowstone last erupted about 640,000 years ago, spewing 240 cubic miles of material. Despite the newly discovered activity, researchers don't expect it to erupt any time soon. Eventually, however, it could explode again as a super-volcano that would destroy life for hundreds of miles around and coat the entire country in ash.
