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

Faulty cement plug may have caused oil rig explosion
As part of the oil drilling process, a cement plug is placed at the bottom of the well in order temporarily to shut it off prior to pumping the oil out; while the cement is drying, mud is loaded into the top of the well to prevent a gas surge; before removing the mud, pressure tests are carried out to ensure the plug is holding; James Dupree, a senior BP official, has claimed that the results of the tests on the Gulf of Mexico plug, carried out on 20 April, were inconclusive — yet the mud was removed

Self-healing concrete developed
University of Rhode Island researchers develop a new type of self-healing concrete that promises to be commercially viable and have added environmental benefits; a microencapsulated sodium-silicate healing agent is embedded directly into a concrete matrix; when tiny stress cracks begin to form in the concrete, the capsules rupture and release the healing agent into the adjacent areas

Italian-Russian reactor could be the first to achieve self-sustaining fusion
As the interest in alternatives to fossil fuels grows, so does the interest in nuclear fusion; a Russian-Italian project will build a self-sustaining fusion reactor based on a design by an MIT scientist; the design employs a doughnut-shaped device which uses powerful magnetic fields to produce fusion by squeezing superheated plasma of hydrogen isotopes

Efficacy of TSA's behavioral threat detection program questioned
Between 2004 and 2008, more than two billion passengers boarded planes at the 161 U.S. airports in which TSA has deployed Behavioral Detection Officers (BDOs) under the Screening of Passengers by Observation Techniques (SPOT) program; the BDOs identified 152,000 passengers for secondary screening, which led to 1,083 arrests; none of those arrested, however, were terrorists or individuals who intended to attack the aviation system; GAO reports that since 2003, there were 16 instances in which airport screeners permitted people to get on planes who later were linked to terror plots

Pentagon directs basic research funds to applied projects, says report
The U.S. Department of Defense has a $13.5 billion science and technology budget; about $1.9 billion — 15 percent of the total — is set aside for basic research; new study found that many of the projects funded under the basic research budget did not meet the definition of basic research used by the Pentagon

World's largest airship inflated Wednesday for the first time
The world’s largest airship — 235 feet long and 65 feet in diameter — was inflated on Wednesday for the first time; the test took place inside the Garrett Coliseum in Montgomery, Alabama which, the proprietors state, can hold as many as 1,500 cattle (“with milking parlor”); the airship features many innovations, including propelling ducted fans which are mounted along the centerline of the hull rather than beneath it, so that the nose does not lift when more power is applied

Katrina, Rita cleaned up polluted, lead-laden New Orleans soil
It appears that hurricanes Katrina and Rita, with all the devastation they have caused, made one beneficial contribution to the future of New Orleans: decades of Louisiana-type corruption and collusion between the oil industry and the state government have caused the city’s soil to be heavily polluted, laden with lead, arsenic, and other poisonous substances; the sediments washed into the city by the hurricanes have blanketed the polluted soil, resulting in a dramatic drop in the presence of lead and arsenic in the city’s soil — and in the blood stream of children in the city

Deep-water oil spills do most of the damage deep down
Oil spills like the one in the Gulf do most of their damage in the deep; the oil visible on the surface accounts for only 2 percent of the oil spilling into the Gulf; most of the oil remains submerged in the form of droplets that only slowly make their way to the surface

Fears grow that Gulf oil could strike Florida
Worries grow over the ecological and economic impact of the huge oil spill, with the most recent fears focused on its possible spread into a “loop current” that could carry the pollution to the Florida Keys and nearby tourist beaches; the U.S. government has already extended fishing closure to nearly 20 percent of the Gulf because of the contamination of harvested seafood

The day of transportable, refrigerator-size nuclear reactor nears
The need for more energy and the growing interest in energy not based on fossil material have led to a revival of interest in nuclear power; there is a competition afoot among several companies for designing and building — and receiving a operation license for — a refrigerator-size nuclear reactor; the $50 million, 25-megawatt unit is transportable by truck, and would put electricity into 20,000 homes

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.
