• History shows more big wildfires likely as climate warms

    The history of wildfires over the past 2,000 years in a northern Colorado mountain range indicates that large fires will continue to increase as a result of a warming climate, according to a new study. Researchers examined charcoal deposits in twelve lakes in and near the Mount Zirkel Wilderness of northern Colorado, finding that wildfires burned large portions of that area during a documented spike in temperatures in North America starting about 1,000 years ago. That period, known as the Medieval Warm Period (MWP), lasted about 300 years, when temperatures rose just under 1 degree Fahrenheit.

  • Immigrants account for a larger share of U.S. science and engineering workforce

    From 2003 to 2013, the number of scientists and engineers residing in the United States rose from 21.6 million to 29 million. An important factor in that increase: over the same time period, the number of immigrant scientists and engineers went from 3.4 million to 5.2 million. Immigrants went from making up 16 percent of the science and engineering workforce to 18 percent, according to a new report.

  • Government climate pledges, if implemented, would warm world by 2.7°C

    The combination of government climate action plans – or Intended Nationally Determined Contributions (INDCs) — if implemented, would bring global warming down to 2.7°C, according to a new analysis. This is the first time since 2009, when the Climate Action Tracker (CAT) began calculating temperature estimates from climate action pledges, that projected warming has dipped below 3°C.

  • Recovering rare earth materials from electric and hybrid vehicle motors

    China currently supplies about 97 percent of rare earth materials used in manufacturing around the world. In an effort to help develop a sustainable domestic supply of rare earth elements and lessen the U.S. dependence on China for materials that are vital to the production of electronics, wind turbines, and many other technologies, researchers have developed a method of extracting rare earths from the drive units and motors of discarded electric and hybrid cars.

  • The growing link between intelligence communities and academia

    The events of September 11 2001 were a catalyst for change in the intelligence profession.One noticeable change: The number of universities offering an intelligence studies-related degree has grown from  a handful to few dozen. Universities are starting to develop curricula that feature practical real-world exercises and structural analytical techniques. This is often happening in collaboration with the intelligence community. Like most businesses or agencies do, universities are starting to develop specific niches. This expansion is being led by the International Association for Intelligence Education (IAFIE), which was formed in June 2004. The field will only grow. It’s a necessary expansion to produce the professionals needed to ensure America’s national security and that of its allies for generations to come.

  • Clothing that guards against chemical warfare agents

    Recent reports of chemical weapons attacks in the Middle East underscore the need for new ways to guard against their toxic effects. Scientists report that a new hydrogel coating that neutralizes both mustard gas and nerve agent VX. It could someday be applied to materials such as clothing and paint.

  • DHS recruits Silicon Valley entrepreneurs to develop first-response technology

    DHS wants better technology for first responders — police, firefighters, and EMTs — but rather than pushing for innovation from within the massive corporations that already provide technology to government agencies, the DHS has come to Silicon Valley to tap the entrepreneurial ecosystem of northern California. Giant technology firms have resources of large scale manufacturing and distribution, but there is one crucial difference. Technology startups are much more nimble, and can shift their development much faster than the huge corporations can.

  • The West is on fire – and the US taxpayer is subsidizing it

    The western United States is burning. This year’s damaging experience is just the latest in a recent series of devastating wildfire seasons, a trend that will only likely increase over the coming years. There are two main reasons behind the growing conflagrations. The first is the legacy of fire suppression polices that snuff out fires as they appear, but leads to the build-up of fuel that is the raw material for larger, more devastating fires. The second is climate change, which is making the West hotter and drier. The higher temperatures wick away moisture from the trees, making them more combustible. The combination of more combustible material and a hotter, drier climate leads to more fires. A number of economic practices and social issues, however, are exacerbating our forest fire problems – chief among them is the enlargement of what is known as the wildland-urban interface (WUI). More people are building homes in the interface close to the wildlands and forests. The full costs of having more people moving into areas subject to greater risk of fire are not borne by these local actors. The federal government picks up between one-half and two-thirds of the cost of protecting people and property in the WUI by providing financial and technical assistance to states and volunteer firefighters. In effect, the federal government, the U.S. taxpayer, picks up the tab. We are on an unsustainable path as the WUI continues to grow and expand, fuel buildup continues and the climate warms. The risk of fire is increasing. But the WUI continues to expand. The U.S. taxpayer should not be subsidizing and underwriting such risky behavior.

  • Flood risk for New York City, New Jersey coast rising

    Flood risk for New York City and the New Jersey coast has increased significantly during the last 1,000 years due to hurricanes and accompanying storm surges. For the first time, researchers compared both sea-level rise rates and storm surge heights in prehistoric and modern eras and found that the combined increases of each have raised the likelihood of a devastating 500-year flood occurring as often as every twenty-five years. “A storm that occurred once in seven generations is now occurring twice in a generation,” says one of the researchers. What does that mean for residents along the New York/New Jersey coast? “An extra 100,000 people flooded in the region during Hurricane Sandy who would not have flooded if sea level had not been rising,” the researcher says of the 2012 storm.

  • Partnering to build climate change resiliency

    South Florida ranks as the world’s most vulnerable urban region because of the large number of assets exposed to the effects of sea level rise. To build climate change resiliency, the Federal Emergency Management Agency (FEMA) partnered with Florida International University (FIU) to provide local community leaders with the knowledge and tools to assess and improve their capabilities to prevent, mitigate, respond to, and recover from climate impacts, including sea level rise, drought and wildfires, heatwaves, floods, powerful storms, and other hazards.

  • Transforming collegiate math experience

    Throughout higher education, math courses have some of the highest failure rates nationwide. Even though math is a skill nearly every person uses on a daily basis, it has become a significant impediment to degree completion. This is what led Florida International University (FIU) to the creation of the Mastery Math program in 2010 — a high-tech, high-touch approach to improving student performance in College Algebra. FIU’s Mastery Math Program, which utilizes evidence-based teaching techniques including peer mentoring and a state-of-the-art computer lab, has since led to other projects that are reversing course on this trend.

  • DOJ grants fund research into homegrown terrorism

    The University of Arkansas (UA) and Arkansas State University (ASU) will receive grants from the Department of Justice (DOJ) totaling over $900,000 to study domestic radicalization. UA will receive $399,531 to identify behavioral characteristics of homegrown terrorists who were able to evade arrest or neutralization for a long period of time to determine how their longevity affects potential recruits and the overall sustainability of larger terror groups. ASU will receive $508,403 to study how violent domestic extremists use the Internet to organize like-minded individuals, disseminate ideas and recruit new members.

  • Small-scale nuclear fusion may be a new energy source

    Nuclear fusion is a process whereby atomic nuclei melt together and release energy. Because of the low binding energy of the tiny atomic nuclei, energy can be released by combining two small nuclei with a heavier one. Fusion energy may soon be used in small-scale power stations. This means producing environmentally friendly heating and electricity at a low cost from fuel found in water. Both heating generators and generators for electricity could be developed within a few years, according to researchers.

  • Robots to pull wounded soldiers off battlefield

    Most Americans have seen at least one war movie, where at some point a fresh-faced young private is hit with some shrapnel. From the ground, he calls out for the unit medic — another young guy, from another small town, whose quick reaction and skill just may save his life. In the near future, however, it may no longer be another soldier, who comes running to his side. Instead, it might be an Army-operated unmanned aerial or ground vehicle.

  • Climate change consensus extends beyond climate scientists

    A survey of nearly 700 scientists from nonclimate disciplines shows that more than 90 percent believe that average global temperatures are higher than pre-1800s levels and that human activity has significantly contributed to the rise. The study is the first to show that consensus on human-caused climate change extends beyond climate scientists to the broader scientific community. Previous studies have shown that about 97 percent of actively publishing climate scientists believe in human-caused climate change, and a review of scientific literature on the existence of climate change indicated that about 97 percent of studies affirm climate change is happening.
