Georgia Tech develop early warning system for tsunamis

Georgia Tech develop early warning system for tsunamis

Posted Thu, 10 Mar 2011 08:09:00 GMT by Michael Evans

A system developed by the Georgia Institute of Technology is able to give coastal residents a 20 to 30 minute warning of a tsunami. It is caused by a wave from an under-sea earthquake, spreading outwards until it reaches land, usually without warning. As the depth of water decreases the wave's pent-up energy creates a devastating wall of water that hits the coastal area, causing massive destruction and often a considerable loss of life.

A recently discovered mature cluster of galaxies seems to be a rare phenomenon - or could the universe have developed differently from what is currently thought? Scientists working from the European Southern Observatory (ESO) in Chile have recently discovered the furthest mature cluster of galaxies away from us which we can still see.

Research at Harvard University has identified the gene that governs colour patterns in mice. Two of the great wonders of Nature are its diversity and its mystery. Why, for instance, do leopards have spots and why do zebras have stripes? Scientists at Harvard University have come a little closer to answering this age-old question.

The immune system of the Nematode worm and how it can help us to manage dangerous infections. Not many people would confess to an admiration for the worm species, and yet a recent study backed by the Biotechnology and Biological Sciences Research Council (BBSRC) has shown that worms are the ultimate gamblers; a type of worm known as a Nematode plays a high-risk game…with disease resistance.

A new report predicts worrying effects on the transpiration of plants. Enjoy basking in the cool shade of an old oak tree in the height of summer? Well, according to American and Dutch scientists it could soon be a less effective way of escaping the heat from the sun. A new study has found that as a result of rising carbon dioxide levels, plants are releasing less water into the atmosphere.

Spraying peppermint with waste-waters from distilling aromatic herbs boosts their essential oil content, according to Mississippi State University researchers. Rather than just discharging waters left over from the processing of herbs, such as sage, rosemary and thyme, it is hoped they can now be used to give their herbal cousins a helping hand.

New models of the huge streams of plasma on the surface of the Sun are raising understanding of the complex mechanisms at play. As the solar sunspot cycle picks up speed, and starts sending out new flares towards the Earth, understanding exactly what makes the Sun tick looks to be increasingly important – for the stability communications and power systems, as well as of the climate.

Florida, the sunshine stats may not be as youthful as looks suggest. A new analysis of samples collected from water boreholes have pushed back the time, when Florida first emerged from the sea, to 45 million years ago. The study describes a familiar landscape of palm trees and islands, and provides useful information for those looking to keep water flowing for local residents.

A new approach to getting organic materials into tiny glass beads opens up a number of new possibilities for intelligent cement – that can heal cracks, and regulate temperatures. This exciting development is described in a thesis presented to the University of the Basque Country, and raises the prospect of buildings lasting longer – and requiring less energy to be heated and cooled.

Monocultures might be the most efficient way to grow but they're also great for the nasties that destroy crops a new report finds. Now scientists have come up with a very good reason for farmers to grow a wider diversity and variety of crops to protect themselves from the changes likely to result from climate change.

Microbes in brewery waste already saves brewers millions by producing methane and now scientists want to put these miniature workers to work on other useful tasks. Cornell scientists have been working with Anheuser-Busch Inbev, which brews Budweiser, to see if microbes which currently produce methane as they break down brewery waste can be put to other uses.

Producing bioethanol from corn residues offers a potentially new twist on the food versus fuel debate. New research suggests that maximizing cellulose production from such residues requires less fertilizer - which also has environmental benefits. But how will that impact grain yields?

A hotter climate could make some plants move downhill to seek water, suggests new research that challenges the assumption that plants would move uphill to reach cooler elevations. Scientists at the University of Montana, the University of California, Davis, and the University of Idaho are the first to find a widespread downward shift in Californian mountain plants.

An epic Montana fossil bed census suggests Tyrannosaurus rex was more of an opportunistic scavenger like a hyena, than an apex predator like a lion. This is the largest study of its kind in the world and the first complete picture of an ancient ecosystem dominated by dinosaurs.

A new species of dinosaur, Brontomerus, literally 'thunderthighs', has been found in a quarry in Utah, USA. Named for it's extremely large thigh muscles, the larger than elephant-sized beast may have used them to kick fight predators or rivals.
