In my earlier post we talked about NASA's Gravity Probe B, not to be left behind European Space Agency ( ESA ) is getting ready to launch their gravity probe-- The Gravity field and steady-state Ocean Circulation Explorer ( GOCE ) scheduled for launch in spring 2008. GOCE is dedicated to measuring the Earth’s gravity field and modelling the geoid with extremely high accuracy and spatial resolution. GOCE data will also be used for probing hazardous volcanic regions and bringing new insight into ocean behaviour. By combining the gravity data with information about sea-surface height gathered by other spacecraft, scientists will be able to track the direction and speed of ocean currents. What will it do? Most of us know that the acceleration due to gravity on Earth's surface is 9.8m per second squared - but, in truth, this figure varies around the planet depending on the nature of the material underneath the earth's surface.The figure varies from 9.78 (minimum) at the equ...

The June report on Trends in Email, Web, and Malware Threats by Secure Computing® Research is out and here are the key findings; Spam Volume Mail volumes remained stable in June with malicious messages making up 85.0% of all email, a 0.57% increase from May. At the end of the month, the Storm Worm gang has released a new variant of the stock spam, unleashing millions of emails with images wrapped up as PDF attachments. Malware Trojans continue to dominate the malware category, accounting for almost 96% of all newly discovered malware. Windows Executables remain the most popular vector for distributing these new attacks. Zombies An average of 236,540 new zombies were detected daily in June, a 32.3% decrease from May. Web Threats An average of 12,436 total new malicious Web sites were detected in June, a 31.28% decrease from the prior month.

While theoretical physicist have come up with new theories to explain the phenomena of gravity, scientists have not given up on Albert Einstein's general theory of relativity, or theory of gravitation.Everybody knows about the Albert Einstein's well established theory of relativity we now call special relativity which leads to E = mc 2 (energy equals mass times the speed of light squared), and is a very well established experimentally.Einstein's also established the general theory of relativity to explain the gravitation and unlike special relativity, surprisingly few tests have been made quantitatively of the results of this theory. But that was until NASA launched Gravity Probe B in April 2004. The data collected by Gravity Probe B during 17 months orbiting around the Earth is putting general theory of relativity to the test.Since October 2005, scientists have conducted painstaking data analysis and validation. The preliminary results were announced in April 2007 for the ...
