Detecting explosives from a distance with laser beams
Scientists have found a way to detect chemicals over long distances, even if they are enclosed in containers; the scientists tested the system by trying to detect frequently used explosives, such as TNT, ANFO, or RDX from a distance – and the tests were successful

Anthrax-decontamination foam used in meth lab cleanup
The meth cleanup problem in the United States is a big one; the U.S. Drug Enforcement Administration lists thousands of locations where law enforcement agencies have found chemicals or paraphernalia indicating the presence of either clandestine drug laboratories or dumpsites; Sandia’s decontamination foam, originally developed to deal with anthrax, is now also a meth eraser

Future aircraft could capture, re-use some of their own power
When an Airbus 320 lands, a combination of its weight and speed gives it around three megawatts peak available power; researchers work on making the aircraft of tomorrow contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity

Wireless bicycle brake to be shown in Cebit 2012
Scientists have developed a wireless bicycle brake; to brake with the wireless brake, a cyclist needs only clench the rubber grip on the right handle; the scientists say the brake has such a high reliability, only three out of one billion braking attempts will fail; “That is not perfect, but acceptable,” says one of the researchers

U.S. water shortages loom
More than 1 in 3 counties in the United States could face a “high” or “extreme” risk of water shortages due to climate change by the middle of the twenty-first century; 7 in 10 of the more than 3,100 U.S. counties could face “some” risk of shortages of fresh water for drinking, farming, and other uses

New app to help fight nonnative species invasion of U.S.
Nonnative species invading the United States — animals, pathogens, and plants — deplete water supplies, poison wildlife and livestock, and damage property in urban and rural areas at a cost of about $138 billion annually; the U.S. Forest Service funded the development of an iPhone application that helps people identify harmful, non-native plants

2010 Russian heat wave caused by both manmade, natural causes
The heat wave that struck western Russia in summer 2010 killed 55,000 people and caused $15 billion in damage; a new study concludes that soaring temperatures were within the natural range for a Russian summer, but that due to human-induced climate change, the chance of such an extreme heat wave has tripled over the past several decades

Recycled glass in cement makes concrete stronger
Researchers have found that by mixing ground waste glass into the cement that is used to make concrete, the concrete is stronger, more durable, and more resistant to water; in addition, the use of glass helps reduce the amount of glass that ends up in landfills

Faculty retention a major challenge for universities
New study shows men and women faculty retained at same rate; but median retention rate for all university professors is only eleven years; if a university hires 100 assistant professors tomorrow, in eleven years only fifty of them will still be at the school

Nuclear waste recycling for better nuclear power generation
Researchers aim to produce safe nuclear fuel that can be 80 percent recycled, compared to the current 1 percent; these fourth generation nuclear power systems can lead to a reduction of the amount of high-level, long-lived nuclear waste to a tenth of what it is today, while energy output can increase hundredfold

Invisibility cloak to protect buildings from earthquakes
Scientists show that by cloaking components of structures with pressurized rubber, powerful waves such as those produced by an earthquake would not “see” the building — they would simply pass around the structure and thus prevent serious damage or destruction
