  • NASA putting satellite eyes on threat to U.S. fresh water

    Algal blooms are a worldwide environmental problem causing human and animal health risks, fish kills, and taste and odor in drinking water. In the United States, the cost of freshwater degraded by harmful algal blooms is estimated at $64 million annually. In August 2014, officials in Toledo, Ohio, banned the use of drinking water supplied to more than 400,000 residents after it was contaminated by an algal bloom in Lake Erie. NASA has joined forces with the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, and U.S. Geological Survey to transform satellite data designed to probe ocean biology into information that will help protect the American public from harmful freshwater algal blooms.

  • Soldiers, astronauts to be protected by tough, flexible new material

    A team of researchers has developed a revolutionary material that has superior anti-penetration properties while remaining flexible. Inspired by the way nature designed fish scales, the material could be used to make bulletproof clothing for the military and space suits that are impervious to micro-meteorites and radiation when astronauts embark on spacewalks. The material emulates the skins of many species of fish — skins which are flexible, but which also protect the fish by hard scales.

  • A surprising source of valuable metals, critical elements: Sewage

    More than seven million tons of biosolids come out of U.S. wastewater facilities each year. About half of that is used as fertilizer on fields and in forests, while the other half is incinerated or sent to landfills. Researchers say that poop could be a goldmine — literally. Surprisingly, treated solid waste contains gold, silver, and other metals, as well as rare elements such as palladium and vanadium which are used in electronics and alloys. The researchers are looking at identifying the metals that are getting flushed and how they can be recovered. This could decrease the need for mining and reduce the unwanted release of metals into the environment.

  • Californians hoping the state would innovative itself out of a water crisis

    California’s water agencies have relied on innovation to cope with the worsening drought and depleting water resources. Irrigation systems have evolved overtime to help the agriculture sector maintain crop yields as temperatures rise and wells begin to dry up.Some are hoping the state would innovate itself out of a water crisis.

  • As the drought worsens, California’s conservation measures fall short

    As the drought worsens, California is doing a poor job of conserving water. Water use has declined by only 2.8 percent in February compared with the same time in 2013. Some Southern Californians are actually increasing their water use. “These are sobering statistics — disheartening statistics, considering how hard we have been working on this,” said Felicia Marcus, chairwoman of California’s water control board, which reported the findings. “We are very concern about these numbers. They highlight the need for further action.”

  • 70 percent of glaciers in Western Canada will be gone by 2100

    There are over 17,000 glaciers in B.C. and Alberta and they play an important role in energy production through hydroelectric power. The glaciers also contribute to the water supply, agriculture, and tourism. A new study says that 70 percent of glacier ice in British Columbia and Alberta could disappear by the end of the twenty-first century, creating major problems for local ecosystems, power supplies, and water quality.

  • Calif. business leaders: State’s worsening water situation threatens economic havoc

    California’s drought outlook is alarming to the point that Governor Jerry Brown recently announced the first-ever mandatory restrictions on water usage, aimed at reducing the state’s urban water use by 25 percent. For much of its history, California has measured up to its challenges while maintaining a healthy economy. Business leaders in the state say that the time has come for California once again to take bold actions to ensure a sustainable future. “We have a choice between protecting our economy by protecting our environment — or allowing environmental havoc to create economic havoc,” said former U.S. Treasury Secretary Robert Rubin, who now co-chairs the Risky Business Project.Driscoll’s CEO Miles Reiter agrees: “The state of California has to deal with groundwater, or we’re going to ruin this state,” he said.

  • How much science, math homework is too much?

    When it comes to adolescents with math and science homework, more is not necessarily better — an hour a day is optimal — but doing it alone and regularly produces the biggest knowledge gain, according to new research. “Our data indicate that it is not necessary to assign huge quantities of homework, but it is important that assignment is systematic and regular, with the aim of instilling work habits and promoting autonomous, self-regulated learning,” said one of the researchers.

  • $500 million, 5-year plan to help Miami Beach withstand sea-level rise

    Miami Beach is investing up to $500 million in a new five-year plan to fortify its coastline against flooding caused by sea-level rise. Between seventy to eighty pumps that will be installed to drain the streets of water as it comes in. Additionally, the city is planning to raise roadways and sidewalks by 1.5 to 2 feet along the western side, which faces the Biscayne Bay. Florida is already seen as one of the most vulnerable states to climate change. Over the past 100 years, sea levels along the coast have risen 8 to 9 inches and are expected to rise by between three and seven inches within the next fifteen years, according to federal government projections.

  • Rutgers receives $1.95 million to prepare professionals for intelligence work

    Rutgers University has received a $1.95 million grant from U.S. intelligence agencies to develop programs that prepare professionals to work in intelligence and national security positions. Through this grant, Rutgers becomes one of eight schools designated as an Intelligence Community Center of Academic Excellence by the Office of the Director of National Intelligence. More than fifty universities nationwide applied for these grants.

  • A very big concept lifts off

    In 2010, a group of defense contractors led by Northrop Grumman received a contract from the U.S. Department of Defense to create a so-called Long Endurance Multi-Intelligence Vehicle (LEMV) — a super-sized surveillance aircraft that had the capability of spending days in the air on a single mission. The first test flight of the Airlander took place in August 2012. In 2013, however, budget cuts led to the cancellation of the project, and U.K.-based Hybrid Air Vehicles (HAV), which was part of contractors group, bought the Airlander back from the DoD at effectively scrap value. So the Airlander came back to the United Kingdom, where it lives in a giant hangar in Cardington, Bedfordshire. It is there because it is the only place in the United Kingdom that can house it, having been built for airship manufacture in 1915. HAH has big plans for it.

  • Louisiana Tech’s concrete canoe, steel bridge teams win big at ASCE competition

    The Louisiana Tech University’s American Society of Civil Engineers (ASCE) Concrete Canoe and Steel Bridge teams swept the 2015 Deep South Conference competition in Oxford, Mississippi recently, bringing nine awards back to Louisiana Tech and earning spots in the national competitions. The Deep South Conference competition, which includes teams from universities in Arkansas, Louisiana, Mississippi, and Tennessee, is held annually to enhance student knowledge of techniques, professionalism, and ethics as they relate to civil engineering, and to allow students to apply the principles and concepts they have learned in their undergraduate studies.

  • California imposes first mandatory water restrictions in state history

    Standing on a patch of brown grass in the Sierra Nevada mountains, which is usually covered with several feet of snow at this time of the year, California governor Jerry Brown announced the first mandatory water restrictions in state history. “Today we are standing on dry grass where there should be five feet of snow,” Brown said yesterday. “It’s a different world… we have to act differently.”About 30 percent of California’s water supply comes from the Sierra Nevada snowpack, so less snow means less snowmelt, which means less water.

  • Extended Oregon drought raises concern over state’s water security

    Facing the fourth straight year of drought, Oregon officials are worried that the state’s water security may be in jeopardy, as is already the case in California, which has just announced its first-ever mandatory water restrictions. a historically warm winter this season has continued to shrink snowpack throughout the Oregon Cascades, including the usual five-foot levels which accumulate on Mt. Hood, leading experts to suggest that even bigger problems lie ahead. Without the usual snowfall, Oregonians can expect fewer healthy fish in the rivers, fewer seed sprouts, and more wild fires. Moreover, the need for more irrigation could hamper the state’s already hobbled farming economy.

  • NSA’s recruitment effort challenged by Snowden leaks, private sector competition

    The NSA employs roughly 35,000 people nationwide and anticipates on recruiting at least 1,000 workers each year. For 2015, the agency needs to find 1,600 recruits, hundreds of whom must come from highly specialized fields like computer science and mathematics. The agency has been successful so far, but still faces recruitment challenges in the aftermath of the Edward Snowden revelations and competition from private sector firms who offer recruits much higher salaries.
