Ancient Rome Rebuilt! Digitally

Rome's Mayor Walter Veltroni will officiate at the first public viewing of "Rome Reborn 1.0," a 10-year project based at the University of Virginia and begun at UCLA to use advanced technology to digitally rebuild ancient Rome.

“Rome Reborn 1.0" shows almost the entire city within the 13-mile-long Aurelian Walls as it appeared in A.D. 320. At that time Rome was the multicultural capital of the western world and had reached the peak of its development with an estimated population of one million.Digital video of the Colosseum.

Researcher says California laws reduce illegal gun purchases

The potential for gun shows to serve as places where criminals obtain firearms can be curbed through increased regulation without adversely affecting attendance or business, according to a new study.

The study, based on field observations made by Garen J. Wintemute, director of UC Davis’ Violence Prevention Research Program, also found that undocumented gun sales between private parties and illegal “straw purchases” in which a person with a clean record buys a weapon for someone with a criminal record were much more common at gun shows in states with little regulation.

Weaker nations win militarily one third of the time, study says

Despite overwhelming military superiority, the world’s most powerful nations failed to achieve their objectives in 39 percent of their military operations since World War II, according to a new University of Georgia study.

The study, by assistant professor Patricia L. Sullivan in the UGA School of Public and International Affairs, explains the circumstances under which more powerful nations are likely to fail and creates a model that allows policymakers to calculate the probability of success in current and future conflicts.

How Sudoku can help you solve the mysteries of graph theory

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?

Can you solve global warming? Make your own computer climate model and see

Think you know how to solve global warming? You'll soon get a chance to find out.

A new Web-enhanced version of the most commonly used climate modeling system will allow scientists, students or anyone else to test their theories about the planet's climate. The Community Climate System Model is already used by thousands of scientists, and the results from their models often make headlines around the world.

The new climate modeling TeraGrid service tool was announced Wednesday (June 6) at the annual meeting of TeraGrid users in Madison, Wis.

High self-esteem may be culturally universal

Digital paper that talks to you

Large boards and store displays already exist as prototypes. They talk to you directly, using digital information embedded in the paper. You simply touch various parts of the display to get information to stream out of printed speakers.

Research teams at the Mid Sweden University forestry industry research program Fiber Science and Communication Network (FSCN) are working on the fourth generation of products that integrate paper with the digital world.
