Electric plants challenged by high temperatures, drought
The hottest July on record since 1895, along with the most wide-spread drought in the country since 1956, have nuclear plants struggling with finding enough water — cool water — to keep key parts of the plants cool; if the water gets too warm, operators have to dial back production — for reactor safety, and also to regulate the temperature of discharge water, which affects aquatic life

Glass offers a better way of storing U.K. nuclear waste
Researchers have shown, for the first time, that a method of storing nuclear waste normally used only for High Level Waste (HLW) could provide a safer, more efficient, and potentially cheaper solution for the storage and ultimate disposal of Intermediate Level Waste (ILW)

How to act if there is a fire on a high-speed train
Researchers have used computer models to analyze the best way to evacuate the Spanish High Speed Train (AVE) in the case of fire; the involvement of the crew in organizing the fast transfer of passengers, completing the process before the train comes to a halt, and collective collaboration to assist those with reduced mobility are just some of the strategies to be followed

Mystery of dramatic leveling off of methane in the atmosphere solved
Increased capture of natural gas from oil fields probably accounts for up to 70 percent of the dramatic leveling off seen in atmospheric methane at the end of the twentieth century; methane has twenty times the global warming potential of carbon dioxide, although CO2 is filling the atmosphere in far larger amounts

Invasion at “Fort Knox of Uranium” raises security concerns
The Y-12 National Security Complex in Oak Ridge, Tennessee, is regarded asthe Fort Knox of Uranium, so the fact that three anti-nuclear activists, one of them an 82-year old nun, were able to breach the high-security complex’s protective fences is not reassuring; that they did so using nothing more than bolt cutters, after announcing their arrival from half-a-mile away, and that they could stay, undetected, in a highly secure area on the nuclear complex’s ground for two hours, is even more worrisome

Y-12 and operator error
Three anti-nuclear activists, led by an 82-year old nun, breached the perimeter security system of the supposedly highly secure Y-2 nuclear facility at Oak Ridge, Tennessee, where nuclear weapons components are manufactured (note that the Oak Ridge National Laboratory [ONRL] is not affiliated with the Y-12 National Security Complex); they then spent several hours in a secure area of the facility, leisurely spray-painting slogans on the facility’s walls – without the facility’s security staff, or the sophisticated $500 million security cameras and sensors, detecting them; to understand what happened at Y-2, we must accept that operator error is an essential problem in national security, and that the problem is pervasive and normal; the only way to deal with the operator error phenomenon is to build redundancies into the system

New device dismantles pipe bombs safely, preserving forensic evidence
Thousands of pipe bombs are made each year, and thousands of pipe bomb threats are called into local police and FBI authorities across the country; many are false alarms, but those that are not can be deadly; dismantling a pipe bomb is tricky and serious business, and missteps during the dismantling process can produce catastrophic results

Geoengineering clouds to slow global warming
Researchers are taking a second look at the possibility of using futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight and thus counter global warming; The theory behind idea, called “marine cloud brightening,” is that adding particles, in this case sea salt, to the sky over the ocean would form large, long-living clouds

Bacteria in tap water traced to the water treatment process
Most of the bacteria that remain in drinking water when it gets to the tap can be traced to filters used in the water treatment process, rather than to the aquifers or rivers where they originated; the findings could open the door to more sustainable water treatment processes that use fewer chemicals and, as a result, produce lower levels of byproducts that may pose health risks; eventually, the work could enable engineers to control the types of microbes in drinking water to improve human health

Aerospace materials for on-site building of pipes of infinite length
Concrete and steel pipes are built in short sections to fit on standard 18-wheel trucks; the heavy industrial manufacturing processes, long-distance trucking, and leak-prone joints used in steel and concrete pipe construction exact a heavy toll on the environment, not to mention bottom line; the solution: a new pipe design, consisting of a central layer of lightweight plastic honeycomb, which can be built onsite as a single section of virtually infinite length

Greenland melting breaks record four weeks early – with two weeks more to go
Melting over the Greenland ice sheet shattered the seasonal record on 8 August — a full four weeks before the close of the melting season; with more melting yet to come in August, this year’s overall melting will fall way above the old records; researchers devise a “cumulative melting index,” which measures the type of melting which adds to the runoff of melt-water that makes sea levels rise
