DARPA funds giant space nets to scoop up space trash
One legacy of the space age is the growing amount of debris — defunct satellites, fragments of rockets, and any unused object originally built and launched by humans — accumulating in space; currently there are 2,465 identified objects of more than two kilograms in low Earth orbit, and these objects threaten projects such as the space elevator; a futuristic company proposes collecting the debris with a dozen space vehicles, each equipped with 200 nets, which would scoop up the debris and then either fling them into the South Pacific, send them closer to Earth where they would eventually decay, or recycle the materials

Small bridge sensors will give early warnings of anomalies, weaknesses
University of Maryland researchers devised a lightweight, low-power, wireless, credit card-sized sensor that will detect weaknesses in bridges and other infrastructure before they can turn into calamities; the sensors would detect anomalies in the structure of even the most inaccessible parts of bridges and send alerts via cellular frequencies to its human masters. Among the things it would measure would be stress loads, vibration, temperature and the creation and growth of cracks

3D, interactive X-ray to offer dramatic improvement in security scans
The latest X-ray scanners can glean information about the atomic or molecular weight of a substance, and so help distinguish between materials, but the results are crude; the best they can manage is to show metal objects in one color, organic materials in another, and everything else in a third color; a new technique — called kinetic depth effect X-ray imaging, or KDEX — builds up a 3D image of the object which can be rotated and viewed from a wide range of angles

Gulf's future depends on oil-eating bacteria, lingering toxicity
Many marine bacteria have evolved to consume oil and other hydrocarbons, and now the spill has allowed these bacteria to follow their food beyond their natural habitat near oil seeps at the bottom of the Gulf; microbes may degrade the oil quickly, but their activity could eventually pose risks to the Gulf’s ecosystem, particularly in the deep ocean; scientists also worry about lingering toxicity — this is because oil’s toxic constituents, such as polycyclic aromatic hydrocarbons, can disrupt reproduction of marine organisms and can lower their offsprings’ vitality; this chronic toxicity will be magnified along the Gulf Coast’s beaches, salt marshes, and wetlands, because oil degradation in these sites will proceed at a much slower pace than in oxygen-rich environments

Hand-held detector sniffs out hidden grave sites
Hidden graves often hold evidence of crimes or atrocities; sniffing dogs are unreliable, and while forensic soil tests are accurate, taking samples from across a wide area and analyzing them just adds to the time it takes to locate a grave; researchers develop a simple hand-held gadget could now let them swiftly scan large areas of ground for signs of a grave

Revolutionizing Resource Renewal: Scaling Up Sustainable Recycling for Critical Materials
Permanent magnets, which retain magnetic properties even in the absence of an inducing field or current, are used extensively in clean energy and defense applications. Rare earths are challenging to access because they are scattered across Earth’s crust, yet they are key components in many modern technologies. Recycled rare earths can be used to make new permanent magnets, accelerate chemical reactions and improve the properties of metals when included as alloy components.
