Holes in Martian moon mystery

The Martian moon Phobos is cratered, lumpy and about 16.8 miles long, or 3 miles longer than the island of Manhattan. According to a recent study, the moon is also unusually light. Planetary scientists found that Phobos is probably not a solid object, and that as much as 30 percent of the moon’s interior may be empty space.

The spacecraft Mars Express snapped this photo of the Martian moon Phobos on March 7.h

Fifa World Cup

A British treasure hunter uncovers valuable new information about England's past

As soon as Dave Crisp noticed a funny signal coming from his metal detector, he put the device down and started to dig. Reaching his hand into the hole he made, he recovered 20 coins that date back to the Roman Empire. After local archaeologists arrived to help, the number of coins climbed to 52,500—including a few hundred that are of special significance to British historians.

What Seeds Do Birds Prefer to Eat?

If you'd like to learn more about the birds in your area, then building a bird feeder is a great way to do that. A well-placed feeder will attract birds, allowing you to get a close-up look without disturbing the birds from behind a nearby window.

This project shows you how to design and build a four-part feeder that will make it easy to figure out what types of seeds your local birds like best. The project is based on an entry to the 2007 California State Science Fair (Fukumitsu, 2007). With this design, you can easily measure the rate at which different types of seeds are consumed. You can also observe which species of birds prefer which part of the feeder. This will give you insight into species-specific seed preferences for your local bird population.

You should do background research on the types of birds in your area. Find out about each bird's preferred habitat and diet. With the right food, you may be able to attract some birds that you don't normally see otherwise. So spend some time in your wood shop, then get out your binoculars and start watching birds!

Ecobot III eats food and needs to poop

Who would have thought that a robot might actually consume actual food and generate organic instead of nuclear waste? That's what a group of researchers at the University of Bristol are doing, working on robots which draw power by digesting food. The Ecobot III is the culmination of their work so far, as it feeds on processed sewage thanks to its 48 microbial food cells. Microbes within will extract energy from the food by digesting it, while the robot will extract some of it by harvesting the electrons put off by the microbes. There was enough energy extracted for the robot to move around, not to mention returning to feed and purge when necessary.
