Californians mull life with less water
Following Californian governor Jerry Brown’s decision to enforce mandatory water restrictions for the first time in history, Californians are planning for changes in their daily lives. Experts say, though, that California cannot resemble its drier neighbor, Arizona. “Without water, you can’t live in California,” Stanford University’s Bill Whalen. “It ties into the California psyche. They have plush lawns and nice gardens that require lots of water. They have the ocean and Lake Tahoe skiing. You have a nice car. You want it clean. You need water. You can’t have California agriculture without water. You lose the nation’s salad bowl.”

Structures tougher than bulletproof vests
Researchers have created new structures that exploit the electromechanical properties of specific nanofibers to stretch to up to seven times their length, while remaining tougher than Kevlar. These structures absorb up to 98 joules per gram. Kevlar, often used to make bulletproof vests, can absorb up to 80 joules per gram. Researchers hope the structures will one day form material that can reinforce itself at points of high stress and could potentially be used in military airplanes or other defense applications.

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.

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.

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.
