Nanostructured material stronger than a speeding bullet
Providing protection against impacts from bullets and other high-speed projectiles is more than just a matter of brute strength; while traditional shields have been made of bulky materials such as steel, newer body armor made of lightweight material such as Kevlar has shown that thickness and weight are not necessary for absorbing the energy of impacts; new tests of nanostructured material could lead to better armor against everything from gunfire to micrometeorites

DARPA seeks multi-band, portable sensor to provide soldiers with clear images
Clip-on or helmet-mounted camera system would fuse useful aspects of visible, near infrared, and infrared images into a single shot under all weather and visibility conditions; the Pixel Network for Dynamic Visualization program, or PIXNET, technology would ingest the most useful data points from each component sensor and fuse them into a common, information-rich image that can be viewed on the soldier’s heads-up display, and potentially be shared across units

The limitations of climate models
How accurate is the latest generation of climate models? Climate physicists have compared them with old models and draws a differentiated conclusion: while climate modeling has made substantial progress in recent years, we also need to be aware of its limitations

Scientists resurrect process to convert sugar directly to diesel
A long-abandoned fermentation process once used to turn starch into explosives can be used to produce renewable diesel fuel to replace the fossil fuels now used in transportation; the retooled process produces a mix of products that contain more energy per gallon than ethanol that is used today in transportation fuels and could be commercialized within 5-10 years

Inflatable giant plugs could have saved NYC subway system
Inflatable plugs being developed with funding from DHS, could have saved some of New York’s subway and highway tunnels from flooding during Hurricane Sandy, according to the developers of the plugs; DHS successfully tested a plug earlier this year, using a 16-foot diameter prototype to hold back pressurized water at a test tunnel in Morgantown, West Virginia; the idea was originally intended to protect tunnels from terrorist attacks

Dutch flood-protection may be suitable for New York, other East Coast cities
Megastorms and disasters are not going to continue to be once in a lifetime storms, but instead become more of an annual occurrence; experts say that the combination of more frequent megastorms and rising sea levels across the east coast would forcemany cities to get serious about flood protection

NY, NJ brace for nor’easter
East Coast resident are still coping with the destruction wreaked by Hurricane Sandy, but now they have to prepare for another potentially destructive storm – a nor’easter which is expected to hit New York and new Jersey on Wednesday; the nor’easter will likely stay 50-100 miles off shore, but its western edges will bring winds of up to 55 mph, coastal flooding, up to two inches of rain along the shore, and several inches of snow to Pennsylvania and New York

Protecting New York City from storms, surges
Almost a week after Hurricane Sandy hit New York City; people are still picking up the pieces of their former lives; for New York officials, the next step is decide how best to protect New York City from a similar disaster in the future; there are many ideas and proposals, ranging from moveable sea gates, to expanding protective marshlands and wetlands, to creating a system of artificial reefs in the channel along the Red Hook and Gowanus neighborhoods of Brooklyn, made out of rocks, shells, and fuzzy rope that will promote the growth of oysters

Nuclear energy facilities proved themselves resilience during Hurricane Sandy
There are thirty-four nuclear energy facilities in the area hit by Hurricane Sandy; all of them have responded well and safely to the powerful storm; the industry says that careful planning and preparations days in advance of the storm paid off at all of these facilities

Hurricane Sandy offered support for reliance on nuclear power
A Scientific American writer is impressed with the way nuclear power facilities were able safely to withstand the wrath of Hurricane Sandy; the lesson he draws from this experience: “Global warming is increasing the probability and destructiveness of extreme weather events like Sandy. (I don’t see the point of dithering over this claim any more.) The last thing we should do in the face of this threat is abandon nuclear energy. If anything, we need more nuclear power, not less, to curb global warming”
