Study explores the use of terahertz sensors
New work into the ability of nanometallic or plasmonic structures to concentrate light into deep-subwavelength volumes holds a promise of new applications for terahertz sensors for improving optical sources, detectors and modulators for optical interconnections, and for creating biomolecules

2010 hurricane season unusually active
As if the on-going oil spill were not enough, people who live near the Gulf of Mexico and the Atlantic should brace themselves for an unusually active hurricane season this year (the hurricane seasons lasts from 1 June to 30 November); FSU researchers say there will be an average of seventeen named storms with ten of those storms developing into hurricanes in the Atlantic this season; the historical seasonal average is eleven tropical storms with six of them becoming hurricanes

Marine camera, integrated software offer improved underwater surveillance, security
Underwater surveillance is one of the more difficult tasks for security personnel; darkness, humidity, murkiness, low temperature all make it difficult for camera equipment to capture clear images of elements in water; a new marine camera with integrated software offers a solution

New automated tool debugs nuclear weapon simulations
The United States relies on nuclear weapons in its deterrence strategy; international conventions, however, prohibit the testing of nuclear weapons; U.S. leaders , military and civilians, must thus rely on simulations to have confidence in the operational reliability of these untested weapons; Purdue researchers offer a new methods to debug nuclear weapons simulations

Oregon town plans first tsunami-resistant building on stilts
Geological findings in recent years suggest there is a one-in-three chance that in the next half century a mega-earthquake will tear the seafloor apart off the Oregon Coast; huge waves would surge onto coastal communities in as little as fifteen minutes; an Oregon city plans tsunami-resistant buildings on stilts

Combining tiny cave camera, iris recognition technology for military, homeland security
Researchers are developing new miniature camera technology for military and security uses so soldiers can track combatants in dark caves or urban alleys, and security officials can unobtrusively identify a subject from an iris scan

Robots with human-like vision to perform dangerous missions
Robots with human-like vision may be deployed to perform maintenance inside nuclear fusion reactors or carry out duties in other areas too dangerous for any person to operate in; a new laser sensor is being developed which will mimic this process by obtaining a coarse image of the scene, performing rapid image analysis to detect objects of interest and subsequently obtaining images with higher temporal and spatial resolution of the detected objects

Berkeley quake demonstration shows bridge safety ideas
Researchers demonstrate new bridge design that can withstand powerful earthquakes; the design concept relies on building segmented bridges with seismic isolators between the segments; the design would be particularly useful for long stretches of elevated freeways and high-speed rail lines that often run on elevated tracks

Crack-proof concrete developed
Researchers develop crack-proof concrete; the construction industry has spent decades looking for materials that would not crack when they are used to repair and reinforce older materials, because even hairline cracks can let in pollutants and start disintegrating the concrete; BASF engineers offer a solution

Worst-case scenario now appears likely
The failure of the top kill technology on Friday to cap the gusher for more than a few hours led both BP and the administration to say that the wellhead will continue to release oil and gas into the Gulf until sometime in late August; this means a spill of between 30,000,000 and 40,000,000 gallons (Exxon Valdez released 10.8 million gallons of oil into Alaska’s Prince William Sound); Now officials and scientists are worrying that the environmental disaster could be compounded by a natural one. the hurricane season starts today and runs through November, and forecasters expect one of the most turbulent seasons ever

BP changes tack on oil spill yet again
After five different approaches to cap the gusher failed, BP will be trying a sixth method: lower a containment cap over the well to pipe the leaking oil to a drill ship on the surface; so far, approximately 30,000 claims have been submitted and more than 15,000 payments have already been made, totaling some $40 million. BP has received more than 110,000 calls to its help lines to date

Carbon Motors’ revolutionary E7 police car already has 14,000 reservations
Carbon Motors offers law enforcement what it describes as the first purpose-built police interceptor; the company says that it already has 14,000 orders for the new cruiser — even though the price for the car has not yet been set; the company says that with the help of more than 3,500 U.S. law enforcement professionals from all fifty States representing the local, state, and federal levels, it wrote the groundbreaking specifications for such a vehicle

New surveillance software knows -- and comments on -- what a camera sees
Software developed which offers a running commentary on CCTV’s images to ease video searching and analysis; the system might help address the fact that there are more and more surveillance cameras — on the streets and in military equipment, for instance — while the number of people working with them remains about the same

Big and small robots showcase their skills at NIST Alaskan events
In the main microrobotics event — the two-millimeter dash — the microbot from Carnegie Mellon University broke the world record held by Switzerland’s ETH Zurich with an average time of 78 milliseconds; the achievement was, well, short-lived: Less than an hour later, the French team shattered the mark with an average time of 32 milliseconds

Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
Tantalizing Method to Study Cyberdeterrence
Tantalus is unlike most war games because it is experimental instead of experiential — the immersive game differs by overlapping scientific rigor and quantitative assessment methods with the experimental sciences, and experimental war gaming provides insightful data for real-world cyberattacks.
Prototype Self-Service Screening System Unveiled
TSA and DHS S&T unveiled a prototype checkpoint technology, the self-service screening system, at Harry Reid International Airport (LAS) in Las Vegas, NV. The aim is to provide a near self-sufficient passenger screening process while enabling passengers to directly receive on-person alarm information and allow for the passenger self-resolution of those alarms.
