Police Department hopes to use flying drones as an extra set of eyes

Behave yourself in Miami, because the eyes-in-the-sky may soon be watching. We're still not sure about all those rumors concerning insect-sized flying vehicles keeping watch over cities, but larger versions certainly seem to be on the way.
Another fascinating find from the Cassini probe has scientists buzzing about one of Saturn's moons
By Gregory MonePosted 03.25.2008 at 10:57 am 5 Comments
The Cassini probe has found evidence that there may be an underground ocean on Saturn's moon Titan. The moon is already an area of tremendous interest to planetary scientists, given its dunes, lakes and mountains. It also has one of the most Earth-like surfaces in the solar system. Now, by using radar measurements to detect changes in the moon's rotation, scientists have gotten more insight into what's below the surface.
The search giant has asked the US government to open air waves to create high-speed wireless connections for all

Google says the US government is ignoring a precious natural resource. And no, the search giant obviously isn't talking about oil. Google, along with other big companies, wants the US government to open up unused air waves. The company says this could lead to people across the country surfing the Web on handheld devices at gigabits-per-second speeds.
Web surfers can follow the travels of a recently released white shark as it heads south

Six weeks ago, the Monterey Bay Aquarium released a young white shark into the ocean, and the swimmer has already cruised down the coast to the waters off Mexico.
The shark, which spent 162 days at the aquarium after it was accidentally caught by a local fisherman, is the first to carry two different tracking tags.
An elderly Australian man kills himself through a home-built, armed robot
By Gregory MonePosted 03.24.2008 at 11:04 am 7 Comments
An 81-year-old man constructed a machine that allowed him to remotely fire a .22 semi-automatic pistol, then set it up in his driveway and killed himself. Reportedly, the man's relatives had been encouraging him to move out of his home and into a care facility.
Instead, he did some research on the Internet and built what was only described as a complex machine—the local paper that broke the story is keeping wraps on how it actually worked.
Deadly soot emerges as a much bigger contributor to global warming than previously believed
By Gregory MonePosted 03.24.2008 at 10:57 am 1 Comment
In a new review article in Nature Geoscience, two scientists say that black carbon, the stuff that gets kicked up into the air from biomass burning and diesel engines, among other things, could account for as much as 60 percent of the warming effect of carbon dioxide. That's three to four times greater than most estimates, and more than that of any greenhouse gas save CO2.
Scientists confirm that the most energetic particles in the universe originate far from our cosmic neighborhood
By Gregory MonePosted 03.21.2008 at 10:02 am 2 Comments
Ultra-high-energy cosmic rays carry more energy than any known particles in the universe, so we should probably all take it as good news that scientists have confirmed that they don't originate in our cosmic neighborhood. In fact, the majority of these rays—which are mostly hydrogen and helium—lose most of their juice on their way towards Earth because they interact with the cosmic microwave background radiation, the energetic leftover of the Big Bang.
The Visible Body offers an educational experience, and the chance to poke a spleen

Let's get to the limitations right away: Mac and even Firefox users will have to sit this one out, since it only runs on a PC, in Internet Explorer. And XP is probably your best bet, too, since Vista users have apparently reported some glitches when using the beta version of this very cool new interactive tool.
All that aside, though, the Visible Body, a new, and free, interactive experience from Argosy Publishing, is pretty mind-blowing. It's Gray's Anatomy in 3-D. (The book, people, not the show.)
A team of researchers performs some nano-magic on a well-known material to increase its thermoelectric efficiency
By Gregory MonePosted 03.21.2008 at 9:46 am 1 Comment
A new low-cost, nanotech-based approach to power generation developed by researchers at Boston College and MIT could lead to cleaner-running semiconductors, air conditioners, car exhausts and more. The technique, published online yesterday in Science, uses the nanostructures to dramatically increase thermal efficiency.
New software predicts where structures could crack under strain
By Gregory MonePosted 03.20.2008 at 9:50 am 0 Comments
Researchers from the University of Wisconsin-Madison and Florida International University have developed a technique that enables them to identify the weak spots in a structure from afar.
The program they developed, Scan and Solve, uses 3D data of an object to predict where it is most likely to fracture, and how its faulty spots will be affected by outside forces such as gravity or other forms of strain.
