Drought, heat turn hundreds of U.S. counties into disaster areas
The U.S. Agriculture Department (USDA) last week said that drought conditions and heat necessitated designating 597 counties in fourteen states as primary natural disaster areas. The affected counties have suffered severe drought for eight consecutive weeks, which qualified them for the automatic designation. 2012 had been the hottest year on record for the continental United States: the year’s average temperature of 55.3 degrees Fahrenheit across the Lower 48, which was more than 3.2 degrees warmer than the average for the twentieth century.

Neutralizing the effects of lethal chemical agents
Organophosphorus agents (OPs) are used both in farm pesticides, and by terrorists and rogue states. About 200,000 people die each year across the world from organophosphorus agents (OP) poisoning, through occupational exposure, unintentional use, and misuse, mostly in developing countries like India, Pakistan, and Sri Lanka and through deliberate terrorist activities. OPs include compounds like Tabun, which was developed in 1936 by German scientists during the Second World War, Sarin, Soman, Cyclosarin, VX, and VR. Researchers develop an enzyme treatment which could neutralize the effects of OPs.

Tiny helpers: Atom-thick flakes help clean up radioactive waste, fracking sites
Graphene oxide has a remarkable ability quickly to remove radioactive material from contaminated water. Researchers determined that microscopic, atom-thick flakes of graphene oxide bind quickly to natural and human-made radionuclides and condense them into solids. The discovery could be a boon in the cleanup of contaminated sites like the Fukushima nuclear plants, and it could also cut the cost of hydraulic fracturing (“fracking”) for oil and gas recovery and help reboot American mining of rare earth metals.

Catching up: Indian and Chinese companies at the forefront of innovation
In a few short years, the Chinese and Indian share of the world’s research and development centers has increased from 8 to 18 percent. A new study says that India and China invest more than the West in organizational innovation, that is, the implementation of a company structure that creates a favorable climate for new inventions.

Students develop low-cost water filtering system for African nation
Every year, 3.4 million people die from lack of access to fresh water globally; in East Africa, daily routines include women venturing miles to secure fresh water and bearing the heavy weight of water containers to secure less-than-desirable water; in an effort to bring fresh water to rural Kenyans, Penn State’s School of International Affairs (SIA) students have developed a ceramic water filtration system for parts of the sub Saharan African nation

Laser weapon tracks, destroys drones, mortar rounds in mid-flight
A 50kW high energy laser (HEL) weapon technology demonstrator successfully passed demanding tests in Switzerland; in the first test, a massive, 15mm-thick steel girder was cut through from a distance of 1,000 meters; even more impressively, the HEL shot down several nose-diving target drones at a range of two kilometers; the drones were flying at speeds over 50 meters a second, but the system’s radar had no trouble picking up the incoming unmanned aerial vehicles at a distance of three kilometers, before they were destroyed by the laser beam at a 2-km range; the HEL also tracked and destroyed a steel ball measuring 82 mm in diameter and travelling at approximately 50 m/sec – replicating a mortar round – in mid-air

Shoring up Long Island’s natural shore defenses against future storms
Sand and other coarse-grained sediments are vital to the naturally occurring barrier systems which dissipate storm surges, protect coastal residences, and shelter biologically diverse estuaries and ecosystems; a team of researchers is conducting marine geophysical surveys of the seafloor and shallow subsurface to assess the health of the offshore barrier system which protects the New York Harbor and southwestern Long Island region against damage from future storms

Fish zapping: shocking Asian carp out of Midwest waters not feasible
The several species known as Asian carp are not native to U.S. waterways but have been found in rivers throughout the Midwest; these fish are competing with native species for food and altering ecosystems; they are also dangerous to boaters and other river users since Asian carp can weigh up to sixty pounds and are known to jump out of the water during even minor disturbances; scientists had hoped to modify or expand low-voltage electrical barriers like those used around Chicago waterways to direct Asian carp from particular areas, but found that the level of electricity needed would be far too high

A 1-kilometer-long electric sail tether brings space sailing closer
The electric sail (ESAIL) produces propulsion power for a spacecraft by utilizing the solar wind; the sail features electrically charged long and thin metal tethers which interact with the solar wind; using ultrasonic welding, researchers have successfully produced a 1-km long ESAIL tether; the produced tether proves that manufacturing full size ESAIL tethers is possible; the theoretically predicted electric sail force will be measured in space during 2013
