Keeping water clean
Researchers develop hydrogel material that can detect and remove contaminants in water; the hydrogel shrinks as it absorbs heavy metal pollutants, signaling the presence of cadmium and other toxic ions, even as it absorbs them from the contaminated water

Detecting rusted metal encased in concrete structures
Many of the problems of aging infrastructure owe to rusting metal; trouble is, much of that metal is encased in concrete — in bridges, tunnels, dams, roads; new technology uses electromagnetic fields to measure corrosion through non-ferrous material

Israel uses new ISR systems, ordnance
Advocates of air power were humbled in the 2006 Israel-Hezbollah war, but they hope to be vindicated in the Israel-Hamas conflict; Israel uses new ISR systems which shrink the sensor-to-shooter loop, and new bunker-busting ordnance

Scientists say comet killed off mammoths, saber-toothed tigers
There is a consensus in the scientific community that the dinosaurs dies off 65 million years ago as a result of a meteorite hitting Earth, sending heavy clouds of smoke and soot which blocked the sun for months, leading to the death of plants on which dinosaurs relied for food; researchers say that 12,900 years ago, a shower of meteorites hitting North America caused the extinction of mammoths, saber-toothed tigers, and other large mammals

"Small is beautiful" comes to the nuclear power industry
The main problem facing nuclear power is not the fear of accidents or terrorism, or anxiety about nuclear waste disposal; it is cost (it takes about $4,000/kilowatt to build a nuclear power station); there is a growing interest in small, tub-size nuclear power units

Government examines, then dismisses, threat of gravitational waves
A U.S. company solicited funds from the Defense Intelligence Agency to examine the threat to the United States from gravitational waves; the agency concludes that notions that these waves might pose a security threat “belong to the realm of pseudo-science, not science” (physicists say you did not need a 40-page report to reach this conclusion)

The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
