• U.S. engineering schools to educate 20,000 students to meet U.S. major engineering challenges

    In a letter of commitment presented to President Barack Obama at the White House Science Fair yesterday, 122 U.S. engineering schools announced plans to educate a new generation of engineers expressly equipped to tackle some of the most pressing issues facing society in the twenty-first century. Each of the 122 signing schools has pledged to graduate a minimum of twenty students per year who have been specially prepared to lead the way in solving such large-scale problems, with the goal of training more than 20,000 formally recognized “Grand Challenge Engineers” over the next decade.

  • California exploring water purification, imports, and conservation as water situation worsens

    California officials are calling on residents better to manage their water usage as the state enters its fourth consecutive year of drought. An average American uses 100 gallons of water each day, and reservoirs in California only have enough water to supply this level of consumption until the end of 2015. In 2014 alone, the state’s agriculture sector lost $2.2 billion in revenue as a result of the drought. State officials acknowledge that a heavy rainfall alone will not be sufficient to restore the groundwater the state needs, so water districts are investing in water recycling plants and exploring strategies ranging from importing water to encouraging greater conservation.

  • Diminished Utah snowpack threatens Salt Lake City water supply

    Studies of water use from 2005 to 2010 show that Utahans used more water for public supply than any other state, despite Utah being ranked the second most arid within the country. Significantly lower levels of Utah snowpack this winter are the biggest climate challenge now facing Salt Lake City: The Northeastern part of the country is inundated with record amounts of snow, but Salt Lake City’s snowpack is 69 percent below the 30-year average.

  • Climate change discussion: Shifting from mitigation to adaptation

    Many infrastructure protection experts say that there is a need to discuss not only how to reduce greenhouse gas emissions, but also how to plan for and adapt to the inevitable consequences of those emissions, which are already changing the climate. One area in which adaptation to climate change is likely to be especially painful is in coastal areas affected by sea level rise. In some coastal regions, communities will be forced to retreat from the coast as a result of rising sea level and increasing damage from storms and flooding. Part of the problem is that policies such as disaster relief programs and insurance regulations create a system that protects many property owners from the true costs of building in risk-prone areas of the coast. “We have a system of private gains and externalized costs,” said one expert.

  • Averting global water crisis

    Climate change is increasing the demand for desalinated water — by 2025,14 percent of the global population will be forced to use desalinated sea water — as greater evaporation and rising seas further limit freshwater supplies for a growing world population. Current methods to desalinate water, however, come at a very high cost in terms of energy, which means more greenhouse gases and more global warming. Carbon nanotube membranes have the potential to tackle the current and future challenges in water purification.

  • Rising seas bring heavy burden to Florida coastal economy. Can it adapt?

    Florida is a coastal state. Nearly 80 percent of its twenty million residents live near the coast on land just a few feet above sea level, and over a hundred million tourists visit the beaches and stay in beach-front hotels every year. The coastal economy in Florida is estimated to account for 79 percent of the state’s gross domestic product, a measure of direct revenue into the economy. It now is widely accepted that climate change is causing an unprecedented rise in sea levels around the world, and that locations such as Florida, where huge infrastructure and large populations live right on the coast, are especially vulnerable. An important reality is that sea-level rise is not a future phenomenon. It has been happening slowly over the past decades, at about one inch every ten years. That’s a half foot since the 1960s and already it is taking a toll.

  • The Brandeis program: Harnessing technology to ensure online privacy

    In a seminal 1890 article in the Harvard Law Review, Louis Brandeis developed the concept of the “right to privacy.” DARPA the other day announced the Brandeis program – a project aiming to research and develop tools for online privacy, one of the most vexing problems facing the connected world as devices and data proliferate beyond a capacity to be managed responsibly.

  • People in coastal zones in Asia, Africa are most vulnerable to sea-level rise

    The number of people potentially exposed to future sea level rise and associated storm surge flooding may be highest in low-elevation coastal zones in Asia and Africa, according to new projections. The researchers assessed future population changes by the years 2030 and 2060 in the low-elevation coastal zone and estimated trends in exposure to 100-year coastal floods. The number of people living in the low-elevation coastal zone, as well as the number of people exposed to flooding from 100-year storm surge events, was highest in Asia. China, India, Bangladesh, Indonesia, and Viet Nam had the largest numbers of coastal population per country and accounted for more than half of the total number of people living in low-elevation coastal zones.

  • Boston prepares for life with rising sea levels

    A 2013 World Bank studylisted only seven cities in the world as more vulnerable to flooding than Boston. The other American cities are Miami, New York, New Orleans, and Tampa. Faced with the prospect of having a significant portion of the city underwater, city officials and private developers have launched a competition to redesign Boston for the year 2100, with the assumption that sea levels will be five feet higher than they are today. The Living With Watercompetition looks to prove that the future of Boston can coexist with rising sea levels.

  • Geologists: Popular Irish tourism hotspot “slowly drowning”

    Geologists have found evidence that Connemara, described by Discover Ireland, a tourism body, as one of the country’s “most iconic destinations,” is slipping under the sea.”It’s certain that the sea has encroached considerably onto the land around Galway Bay since the ice melted…and that the strange, watery landscape is indeed being shaped by a slow drowning”of Connemara, said Jonathan Wilkins, a geologist with the Earth Science Ireland (ESI) group.

  • Lockheed Martin recognized for supporting young girls’ STEM education

    Over the next eight years there will be more jobs available in Science, Technology, Engineering, and Mathematics (STEM) than any other occupation. The Society of Women Engineers (SWE) recently presented Lockheed Martin with its first “Invaluable” award for championing education programs that inspire the next generation of women engineers and technologists. Since 2010, Lockheed Martin has given more than $45 million to programs that promote STEM education.

  • Latest version of laser weapon system stops truck in field test

    Lockheed Martin’s 30-kilowatt fiber laser weapon system successfully disabled the engine of a small truck during a recent field test, demonstrating the rapidly evolving precision capability to protect military forces and critical infrastructure. The company says that the ground-based prototype system, — called ATHENA, for Advanced Test High Energy Asset — burned through the engine manifold in a matter of seconds from more than a mile away. The demonstration represents highest power ever documented by a laser weapon of its type

  • Lack of evidence-based terrorism research hobbles counterterrorism strategies

    The Global Terrorism Database at the University of Maryland estimates that groups connected with al-Qaeda and the Islamic State committed almost 200 attacks per year between 2007 and 2010. That number has increased to about 600 attacks in 2013. As terrorism becomes more prevalent, the study of terrorism has also increased, which, in theory, should lead to more effective antiterrorism policies, and thus to less terrorism. The opposite is happening, however, and this could be partly due to the sort of studies which are being conducted. The problem: few of these studies are rooted in empirical analysis, and there is an “almost complete absence of evaluation research” concerning anti-terrorism strategies, in the words of a review of such studies.

  • Sea level rise causing changes in ocean tide levels, tidal ranges

    Scientists have found that ocean tides have changed significantly over the last century at many coastal locations around the world. Increases in high tide levels and the tidal range were found to have been similar to increases in average sea level at several locations.

  • “Pee-power” to light refugee camps in disaster zones

    A toilet, conveniently situated near the Student Union Bar at the University of the West of England (UWE Bristol), is proving pee can generate electricity. The prototype urinal is the result of a partnership between researchers at UWE Bristol and Oxfam. It is hoped the pee-power technology will light cubicles in refugee camps, which are often dark and dangerous places particularly for women. Students and staff are being asked to use the urinal to donate pee to fuel microbial fuel cell (MFC) stacks that generate electricity to power indoor lighting.
