The guts of the Earth can be "seen" by scientists who study seismic waves after earthquakes. The water got there through plate tectonics, scientists figure and this process caused the ocean bottom to be pulled beneath continental plates all around the Pacific Rim. Now, that's pretty cool.

Curiously, the Ocean Sunfish has a very small brain compared to its size: A 200 kg specimen may have a brain the size of a nut weighing only 4 g. It would explain their quiet behaviour and how often they get trapped into fisher nets.
According to the National Geographic if it lives to adulthood, a sunfish can gain over 60 million times its starting weight: "the equivalent of a healthy, bouncing human baby growing to a weight equal to six Titanics".

Others resembled corals and shrimps. At least 30 appear to be new to science, said Julian Gutt, chief scientist of an expedition that was part of the International Polar Year research effort set to launch on March 1. The researchers catalogued about 1,000 species in an area of the Antarctic seabed where warming temperatures are believed to have caused the collapse of overlying ice shelves, affecting the marine life below.
“This is virgin geography,” said expedition member Gauthier Chapelle. “If we don’t find out what this area is like now following the collapse of the ice shelf, and what species are there, we won’t have any basis to know in 20 years’ time what has changed and how global warming has altered the marine ecosystem.” [continue article]

Not that I have Vista or plan to get it anytime soon, but it's nice to know that new technology is taking mapping and GIS very serious. The Google Earth & Microsoft Virtual Earth battle is being incorporated into new software very easily.
The much publicized Google Mapping of Australia that began last month no doubt worked as a good promotion for the already popular Google Earth.
It now appears that the New York Times Travel has hit the mother load of Google Maps integrations by mashing up almost all of their Travel Guide pages and nearly all the hotels, restaurants and such for each guide which are plotted on the respective maps for each location.

One tip - on the Iraq League site, one of the best known - is for people to draw up maps of their local area using Google Earth’s detailed imagery of Baghdad so they can work out escape routes and routes to block.
It’s another example of the central role technology plays in the conflict - with the widespread use of mobile phones, satellite television as well as the internet - by all sides and for many purposes.

The city plans to create a digital, three-dimensional map of Shanghai that can be easily searched online. The project will be similar to Google Earth, a site that lets you study satellite images of the planet, but will provide an even better look at the city's architecture, according to Shu Rong, a researcher with the Shanghai Institute of Applied Physics, which will provide airborne camera technology for use in the project.
Users will be able to view the map using a PC or cell phone.
"The map will provide a vivid city tour," Shu said, noting it will include pictures of the sides of buildings, unlike the Google site which only provides a birds-eye view of cities.
An engineering marvel or a colossal eyesore, depending on who is describing it, the horseshoe-shaped glass walkway will jut out 70 feet beyond the canyon's edge on the Hualapai Indian Reservation just west of Grand Canyon Village. Buttressed by 1 million pounds of steel and supporting 90 tons of tempered glass, the see-through deck will give visitors a breathtaking view of the canyon.

GPS units are put into shoes because shoes aren't as easy to lose, unlike phones, watches and bracelets. The Quantum Satellite Technology promises to locate the wearer anywhere in the world with the press of a button
Take a time-out from your work. The newest trailer for Shrek the Third is online. Enjoy!

Fuzzy, low resolution pictures and distorted building plans is how the government and Google Earth have agreed to get around concerns that images of sensitive military and scientific establishments available on the Web could either allow unauthorised snooping or become a ready reckoner for terrorists.
At a recent meeting between ministry of science and technology officials and Google Earth representatives, it was decided that installations identified by government would be carefully camouflaged. This, it was felt, was better than an outright blackout. Apart from well-known sites like BARC, there are many less prominent ones, and blacking them out would only attract attention to their locations.
Images of these locations will not be of more than 25-50 metre resolution, more like the older generation pictures provided by Indian Remote Sensing satellites. Official sources said Google Earth would distort building plans by adding structures where none existed or masking certain aspects of a facility. This could be done without attracting attention to such establishments, which range from laboratories, mines, military sites, space and atomic centres and residences of high-profile VVIPs.
The government list of such sites would be accepted by Google Earth. The controversy over Google Earth's images had gained momentum after Kalam, in October last year, expressed concern that unrestricted pictures on the web could have worrisome security implications. [via]

beermapping.com is a project by someone who likes knowing exactly where he is and how far he needs to go for good beer. At this point, there is only one individual working on the Beer Mapping Project. But that one person has been supported by many friendly craft beer lovers who offer suggestions for new maps and they help by beta testing each map. Use the Contact Us link if you have something to say about the Beer Mapping Project, or if you think you could help out.
Beer Mapping Project is utilizing Google’s Mapping API that is offered free for anyone who is not making a profit or charging users to use the maps that are using it. Each location is pushed through a geocoder service (beermapping.com is now getting geocodes through Yahoo’s API) in order to get the latitude and longitude for the particular location. Sometimes these geocoders do not produce results that are exact. Leading to locations that are either slightly wrong, or really wrong. Because of this chance of error, please double check with the website of the location you wish to travel to. Do not take for granted that each location is mapped perfectly.
Until Now. Lars Bromley at the American Association for the Advancement of Science has just posted a much more complete set of annotated overlays for Lebanon and Zimbabwe, and also a timeline-enabled set of placemarks documenting attacks on civilians in Darfur during September-December 2006. The imagery of Zimbabwe and Lebanon is regions-enabled, properly aligned, and with impeccable sourcing. Lars says we should expect to see more of where this comes from.
I think it's great to see the fruits of scientific progress find such immediate, humanitarian uses. While it may not have been the case in the past, future leaders must now know that the humanitarian toll of their actions will be visible to all, archived, and pored over in minute detail when its time to write their histories.
