Scientists in the Netherlands unveiled the largest radiotelescope in the world on Saturday, saying it was capable of detecting faint signals from almost as far back as the Big Bang.

The term means a sixth sense for guessing who is gay.

According to the Dutch researchers who carried out the study, gay people have better attention to detail than their straight counterparts.

For insight into what can happen when the Earth's carbon cycle is altered — a cause and consequence of climate change — scientists can look to an event that occurred some 720 million years ago.

Volcanoes can radically alter climates. We know that. But we are now learning that the reverse also holds: Climate change is causing volcanic eruptions—as well as earthquakes and tsunamis.

Here a good page in geology.com on the various kinds of rocks. an overview. Rocks: Pictures of Igneous, Metamorphic and Sedimentary Rocks.

The airspace over much of northern Europe remains shut and the Norwegian Prime Minister, Jens Stoltenberg, is stranded in New York City because of the threat from a volcanic ash plume being belched out of Iceland. How long will the eruption of the Eyjafjallajokull volcano continue and what other kinds of activity can we expect? A volcanologist at the Norwegian University of Science and Technology (NTNU) who has worked extensively in Iceland says a month-long eruption would not be out of the question. But the eruption could also continue for a year or more, he says.

An unprecedented number of tiny, ocean dwelling organisms have been catalogued by researchers involved in a global survey of the world’s oceans.

One of the highlights was the discovery of a vast “microbial mat”, covering an area equivalent to the size of Greece.

Microbes are estimated to constitute up to 90% of all marine biomass.

The findings form part of the Census of Marine Life (CoML), a decade-long project that will present its full results in October.
