"Even after melting, the stone [produced from the thunderstorm that struck Vivian, South Dakota, U.S. of A., on 23 July 2010] still measured 8.0 inches in diameter and weighed nearly 2 pounds (1 pound, 15 ounces) with a circumference of 18.62 inches."

A newly discovered type of oil-eating microbe is suddenly flourishing in the Gulf of Mexico. Scientists discovered the new microbe while studying the underwater dispersion of millions of gallons of oil spilled into the Gulf following the explosion of BP's Deepwater Horizon drilling rig.
Astronomers discover a planetary system containing at least five planets orbiting a star much like our Sun.
While some airlines have done experiments in running planes on biofuels, air travel normally requires an enormous output of carbon-emitting jet fuel. Various factors, like plane models, total load, and chosen route can effect one trip's fuel efficiency, but which airlines consistently manage to use the least fuel in their operations?
The moon may be shrinking, but it's still a big enough ball of fun to warrant its own night in the limelight.On September 18 people around the planet will be gathering for the first ever International Observe the Moon Night, a global event meant to get people excited about lunar science and exploration. The whole thing started with a national.....
A year and a half after President Obama loosened restrictions on government funding of human-embryonic-stem-cell research, a federal judge declared all such studies temporarily off-limits for taxpayer dollars, on the grounds that they violate a 1996 law.
A report from Beyond Zero Emissions asserts that Australia's energy needs can be fully met by renewable sources within 10 years with technologies that are already available, with 40% coming from wind generation, and 60% from large-scale Concentrating Solar Thermal with molten salt storage.
Take a look at the world’s energy consumption as a factor of renewable and non-renewable energy resources.
2010 has been dominated by extreme natural phenomena, becoming known as the year of global weirding. Heat waves are just one of the many dramatic forces in weather that have been wreaking havoc across the world, scorching populations from South America to the Middle East.
Charles Darwin may have been wrong to argue that competition was the major driver of evolution, a study suggests.
European astronomers on Tuesday said they had found a distant star orbited by at least five planets in the biggest discovery of so-called exoplanets since the first was logged 15 years ago. One of the planets is nearly the mass of Earth.
Scientists reported progress today in using a common virus to develop improved materials for high-performance, rechargeable lithium-ion batteries that could be woven into clothing to power portable electronic devices.
If you had a dinner invitation in Utah's Escalante Valley almost 10,000 years ago, you would have come just in time to try a some new menu items.
The rotating corpses of massive stars can help scientists weigh the planets in the solar system. By carefully timing radio blips from spinning stellar leftovers called pulsars, astronomers have measured the masses of all the planets from Mercury to Saturn, plus all their moons and rings.
The 'mystery stone' discovered on a mountainside in New Mexico, appears to be inscribed with ancient Greek or Hebrew. For decades, scholars have wondered if it's proof that Mediterranean peoples came to the New World thousands of years ago.
What's the matter with this cluster of galaxies? To find out what forms matter takes in the Abell 1689 cluster requires not only deep images from telescopes like the Hubble Space Telescope, but detailed computer modeling as well.
Two scientists, one American and one French, have been in Chernobyl for more than 10 years studying the populations of insects, birds and mammals in "zone of alienation" surrounding the abandoned nuclear power station
