It may not sound like a great thing for your backyard festivities but scientists have figured out how to make the fruit fly live longer. Luckily, humans will get something out of the deal -namely the discovery that a single protein can inhibit aging means we might live longer to be annoyed by insects.

Though the dense humid forests of Central Africa have been regarded as among the most pristine on Earth, the expansion of industrial logging and the accompanying proliferation of road density are threatening the future of this important ecosystem.

Have you ever been trying to solve a Sudoku puzzle and been gripped by a sinking feeling that maybe you were stuck with a lemon? That maybe the puzzle you are struggling with actually has no solution at all and, if you do find a solution, how can you be sure it's the only one? What if half an hour ago you had written 5 instead of 3---would you then have gone down a path to a completely different solution?

The authors of a new study use tools from the branch of mathematics called graph theory to systematically analyze Sudoku puzzles.

The Milky Way's total mass is about 100 billion solar masses - enormous to us but average among galaxies. It spirals around a black hole that is about three million solar masses, say cosmologists.

Imagine it meeting an identical twin. Were they to merge they would produce a galaxy that's even greater. Cosmologists think that's how galaxies grow; through a complex process of continuous mergers.

Much cooler than a flaming Optimus Prime, more practical than Big Guy and Rusty The Boy Robot - they're rescue robots, and they're here to help.

NIST engineers are organizing the fourth in a series of Response Robot Evaluation Exercises for urban search and rescue (US&R) responders to be held on June 18-22, 2007, at Texas A&M’s “Disaster City” training facility in College Station, Texas.

The peculiar pose of many fossilized dinosaurs, with wide-open mouth, head thrown back and recurved tail, likely results from the agonized death throes typical of brain damage and asphyxiation, according to two paleontologists.

A classic example of the posture, which has puzzled paleontologists for ages, is the 150 million-year-old Archaeopteryx, the first-known example of a feathered dinosaur and the proposed link between dinosaurs and present-day birds.
