Study finds more spending on fire suppression may lead to bigger fires
Researchers found that fire management can fall into the firefighting trap: Energy and resources are spent mostly on fire suppression — putting out fires in the moment — while less attention is devoted to fire prevention, such as clearing brush and building fire lanes during the off-season. After severe fires, policymakers funnel even more funds into fire suppression for the next season, but this attention to fire suppression may undermine prevention efforts. The result, counterintuitively, is even worse fires the following season, due to the buildup of fire-prone materials such as dried tinder and dead trees. The researchers emphasize balancing fire suppression with prevention measures.

Financial decision making, risk taking in the face of changing climate
Maximizing returns on financial investments depends on accurately understanding and effectively accounting for weather and climate risks, according to a new study by the American Meteorological Society. An AMS report concludes that financial investments face a range of risks due to existing weather patterns and climate variability and climate change. Even small changes in weather can impact operations in critical economic sectors. At the same time, climate variability and change can either exacerbate existing risks or cause new sources of risk to emerge.

Fashion scouts and cops: the logic behind stop-and-frisk
New research compares practices used by fashion industry casting directors to the New York City Police Department’s controversial stop-and-frisk program. Fashion casting directors belong to a select group of mediators responsible for shaping the pool of modeling talent by scouring familiar territory for the young and beautiful. These casting directors had been similarly indoctrinated into the industry and the talent they would choose often resulted in over-representation of certain kinds of people. Similarly, police officers are a select group responsible for making a city safer. Their training — reinforced daily through the institutionalization and public acceptance of such practices — disposes them to scour familiar geographical and social territory for potential criminals, often resulting in over-representation of people from certain groups.

Security agencies concerned about plastic guns
The Undetectable firearms Act of 1988, which makes it illegal to manufacture, import, sell, ship, deliver, process, transfer, or receive a firearm which is not detectable by walk-through metal detection, is set to expire on 9 December 2013. If Congress fails to reauthorize the law, plastic guns will no longer require metal components which are detectable by metal detectors. “When these 3D firearms are manufactured, some of the weapons can defeat normal detection such as metal detectors, wands, and it could present a problem to public safety in a venue such as an airport, an arena, a courthouse,” says ATF assistant director Richard Marianos.

Using gaming to spark kids' STEM interest, improve physical fitness
A team of Purdue University technology researchers will use a $1.2 million National Science Foundation grant to tackle two national challenges: increasing children’s interest in science, technology, engineering, and math (STEM); and decreasing childhood obesity. The three-year project parlays kids’ innate interest in video games and solving big problems to inspire them to gain the STEM skills needed to create technology-based fitness games. The project will also encourage students to create exergames that require players to get up and move.

U.S. oil production exceeds imports for first time in two decades
The United States is well on its way to energy independence, with the Obama administration announcing Wednesday that domestic oil production surpassed imports for the first time in nearly two decades. A report by the U.S. Energy Information Administration (EIA) offers proof that the United States has managed both to increase domestic oil and gas drilling and reduce the nation’s carbon emissions, which have dropped to a 20-year low. Since 2008, U.S. crude oil output has increased 50 percent, while imports have fallen about 20 percent.

Wrong crowd: social networks are key to city violence
A new study of gun violence in Chicago reveals that a person’s social network is a key predictor in whether an individual will become a victim of gun homicide, even more so than race, age, gender, poverty, or gang affiliation. “Risk factors like race and poverty are not the predictors they have been assumed to be,” one of the researchers said. “It’s who you hang out with that gets you into trouble. It’s tragic, but not random.”

The Philippines is victim of geography, poor infrastructure, poverty
Owing to its location and geography, the Philippines is one of the most natural disaster-prone countries in the world. On average the country experiences nine major typhoons and 900 earthquakes annually, and it has twenty-five active volcanoes. Poor infrastructure and pervasive poverty exacerbate the impact of disasters, making them even more deadly and destructive. “In a cruel cycle, poverty and underdevelopment make disasters worse, and disasters make poverty and underdevelopment worse,” one observer notes.

Past as prologue: Insights from past natural disasters relevant today
The increasing frequency and intensity of natural disasters constitute a daunting challenge to modern society, which is characterized by a heavy infrastructure and increasing population density. Until now, coping with natural disasters has involved expensive state intervention and technology-aided approaches, but researchers believes that the past contains a wealth of unexploited resources which could also provide solutions to the problems communities face when dealing with need to cope with, and recover from, natural disasters.

Sequestration already eroding U.S. research capabilities
As congressional budget leaders continue negotiations over Fiscal Year 2014 spending levels, three organizations representing the U.S. leading public and private research universities say that the results of a new survey reveal the pernicious impact of sequestration on scientific research across the country. Budget cuts have already led to fewer grants, cancelled projects, staff reductions, and reduced learning opportunities. “If Congress fails to reverse course and doesn’t begin to value investments in research and higher education, then the innovation deficit this country is facing will worsen as our foreign competitors continue to seize on this nation’s shortfall,” the leader of one of the organizations said.

Climate scientists say renewables are not enough
Some of the world’s top climatologists have declared their support for nuclear energy as a complementary energy source, alongside wind and solar as energy, which would cut fossil fuel pollution and reduce the growth of global warming. The scientists say that opposing fossil fuels and promoting renewable energy sources offer but a limited solution.
