'Cascade of events' caused sudden explosion of animal life Posted: 19 Sep 2013 11:22 AM PDT The explosion of animal life on Earth around 520 million years ago was the result of a combination of interlinked factors rather than a single underlying cause, according to a new study.

Geologists simulate deep earthquakes in lab Posted: 19 Sep 2013 11:22 AM PDT Geologists have shown how deep earthquakes can be simulated in the laboratory. The experiments were performed using a new type of apparatus that uses synchrotron X-rays.

Scientists reveal how beta-amyloid may cause Alzheimer's Posted: 19 Sep 2013 11:21 AM PDT Scientists have shown how a protein fragment known as beta-amyloid, strongly implicated in Alzheimer's disease, begins destroying synapses before it clumps into plaques that lead to nerve cell death.

Seismologists puzzle over largest deep earthquake ever recorded Posted: 19 Sep 2013 11:21 AM PDT A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers, the intense pressure on the fault should inhibit the kind of rupture that took place.

Clues to growth of colossus in Coma cluster of galaxies Posted: 19 Sep 2013 11:21 AM PDT Astronomers have discovered enormous arms of hot gas in the Coma cluster of galaxies. These features, which span at least half a million light years, provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the Universe held together by gravity.

Giant prehistoric elephant slaughtered by early humans Posted: 19 Sep 2013 05:57 AM PDT Archaeologists have found evidence that early humans, who lived thousands of years before Neanderthals, were able to work together in groups to hunt and slaughter animals as large as the prehistoric elephant.

Nanoscale neuronal activity measured for first time Posted: 18 Sep 2013 10:06 AM PDT A new technique that allows scientists to measure the electrical activity in the communication junctions of the nervous systems has been developed, and offers a new and unique viewpoint into something not seen before in science.
