We'd like to think of ourselves as dynamic, unpredictable individuals, but according to new research, that's not the case at all. In a study published in last week's Science, researchers looked at customer location data culled from cellular service providers. By looking at how customers moved around, the authors of the study found that it may be possible to predict human movement patterns and location up to 93 percent of the time. These findings may be useful in multiple fields, including city planning, mobile communication resource management, and anticipating the spread of viruses.
Stock markets in Dubai were down this morning as investors reacted nervously to the latest proposed solution to Dubai World’s $22 billion (£14 billion) debt crisis.
The city’s main index, the Dubai Financial Market fell 0.83 per cent in early trading as it emerged that the troubled state-owned conglomerate plans to offer its creditors just 60 per cent of their money back.
The exchange plunged 3.5 per cent yesterday when news of the proposal first leaked. Dubai World has been locked in talks with creditors for almost two months and bankers said yesterday that the two sides remain poles apart on the substantial issues of the negotiations.
The idea of Jupiter as protector was first proposed by planetary scientist George Wetherill in 19941. Wetherill showed that the planet's enormous mass — more than 300 times that of the Earth — is enough to catapult comets that might hit Earth, like a slingshot ,out of the Solar System. Other astronomers have postulated that Jupiter's gravitational pull would thin the crowd of dangerous asteroids and other objects, making Earth less impact prone. Other research has suggested that, in the past, changes in Jupiter's orbit might have actually increased the number of objects on a collision course with earth. Until now, Horner says, little work was done to test either idea.
This is a great article on social connections across the US as shown on facebook.
The maps are interesting.
Looking at the network of US cities, it’s been remarkable to see how groups of them form clusters, with strong connections locally but few contacts outside the cluster. For example Columbus, OH and Charleston WV are nearby as the crow flies, but share few connections, with Columbus clearly part of the North, and Charleston tied to the South
Good article on the relative impact of earthquakes.
The devastating earthquakes that hit China on 12 May 2008, Italy on 6 April 2009 and Haiti one month ago all measured above 6.0 and took many lives. But why was the human cost so much greater for Haiti?
