University of Miami scientists have developed a mathematical model to explore scenarios, assess risks and make predictions for present and future insurgent wars When bombs and bullets left 37 dead during Friday prayers at a mosque in Pakistan, earlier this month, the insurgency was using the element of surprise. Unpredictability is the hallmark of modern insurgent attacks such as this one. However, the likelihood of such events, their timing and strength can now be estimated and managed...

By Neil Johnson, Tampa Tribune, Fla. Jun. 25--TAMPA -- The once-weekly watering rules in effect for 18 months will go on until September. The Southwest Water Management District on Tuesday approved a three-month extension of rules designed to help the water system recover from two years of drought.

Jun. 24--TAMPA -- After a rainy weekend that made searching the Internet for blueprints to build an ark seem like a sound idea, you might think conditions are sodden enough to lift some of the tightest lawn watering restrictions in the state. Rainfall on Saturday set a record at Tampa International Airport. The Manatee River is flooding. The state's wildfire season is about doused. That still isn't enough to let folks turn on their sprinklers twice...

By Neil Johnson, Tampa Tribune, Fla. Jun. 20--TAMPA -- A tardy and fitful start to the summer rainy season and a dry end of spring mean the Hillsborough River is lower than it should be at this time in June, and Tampa water customers will see a small bump in bills because of it. Unable to get enough from the Hillsborough River, the city had to turn to the regional water utility to meet demands of its water customers by purchasing nearly 285 million gallons from Tampa Bay Water in March,...

By Neil Johnson, Tampa Tribune, Fla. Sep. 17--TAMPA -- Starting Oct. 1, weather enthusiasts in Florida can join a 22-state network of volunteer observers who measure and report rainfall for a free online database. The nonprofit network has about 5,500 members and is run through Colorado State University with a grant from the National Oceanic and Atmospheric Administration. The goal is providing better measurements by gathering rainfall, hail and snowfall information from as many...
