Predictable Patterns in Earthquake Activity

11/16/2017
More
Natural variations in the length of the day may influence the likelihood of strong earthquakes happening. The speed of the Earth's rotation can be changed by events in the core, or changes in ocean currents, so that the day grows or shrinks by just a thousandth of a second. But geologists have seen that years with longer days can also have several more strong earthquakes, and we're entering such a phase just now. One explanation they propose is that stress changes due to the speed...

More
Litigation and Science Publishing News that a scientist in the US is suing a fellow scientist, and the National Academy of Sciences, for libel, is worrying the science publishing community. Will litigation spoil the normally, fair and open exchanges that drive scientific progress? Transgenic Skin Transplant Clinicians have created transgenic stem cells to produce replacement skin for a child with a devastatingly debilitating skin disease. The team grew enough skin to transplant 80% of the...

Hidden Secrets of the Great Pyramid

More
A hidden void has been uncovered under the Great Pyramid in Giza. Using a new technique using muons which are a by-product of cosmic rays from the Universe. Explorers have visualized what they think could be a large void at least 30 metres long above the Great Gallery in the 4500 year old Pharaoh Khufu’s Pyramid. Atlas of the Underworld When the Earth’s crust slides under the surface at subduction zones, you might expect that the rock melts and gets amalgamated into the Earth’s Mantle....

Catastrophic Decline in Flying Insects

10/26/2017
More
A few decades ago, when you drove down a country road anywhere in Europe, your car windscreen would get splattered with the squashed bodies of flying insects. It's known as the 'windscreen phenomenon'. But now, there seem to be far fewer flying insects than there used to be. Scientists have long suspected that insects are in dramatic decline, but new evidence confirms this. Research at more than 60 protected areas in Germany suggests flying insects have declined by more than 75% over the...

The Biggest Explosions in the Universe

7/27/2017
More
An international team of scientists have captured the biggest explosions in the Universe in unprecedented detail for the first time. These Gamma Ray Bursts sometimes last for just a few milliseconds, but for that time are trillions of times brighter than our Sun. The chance of capturing one of these rare bursts, which occur just as a dying star collapses into a black hole, is just an incredible one-in-10,000. Sight and Sound Despite the intuitive feeling that we can listen to something...
