Winners of the annual Rube Goldberg Machine Contests
Rube Goldberg machines combined simple household items into complex devices to perform trivial tasks; the machines combine the principles of physics and engineering, using common objects; the theme for the 2010 national Rube Goldberg contest: to build a machine which would dispense an appropriate amount of hand sanitizer in someone’s hand — and do so in at least twenty steps; a University of Texas team built a machine that dispenses the hand sanitizer in 46 steps

Cutting-edge laser technology for crime labs developed by FIU research team
Determining the precise composition of a substance with LIBS can provide important evidence in legal proceedings. Trace elemental analysis for comparisons of glass, paint chips, soils, paper, ink on paper, and metal fragments has been shown to be highly effective; the instrumentation required for this kind of analysis in forensic comparisons, however, has been beyond the reach of many forensic laboratories; researchers at Florida International University offers a solution

Day of trained sniffing bees is here
The bee’s discreet sense of smell, equivalent to a dog’s, is being exploited as a much cheaper way to detect various odors in the environment; a U.K. company is now training bees to sniff out explosives and land mines — but also to identify diseases and cancers in people and animals, detect rapidly spreading bacteria in food, and identify dry rot in buildings

New research points way to safer nuclear reactors
Self-repairing materials within nuclear reactors may one day become a reality as a result of research by Los Alamos National Laboratory scientists; when designing nuclear reactors or the materials that go into them, one of the key challenges is finding materials that can withstand an outrageously extreme environment; researchers find that nanocrystalline materials may offer an answer

Day nears for restarting Japan's fast-breeder reactor - the world's only such reactor
Monju, the world’s only fast-breeder reactor, achieved criticality in April 1994; in December 1995 a coolant loop leaked more than 700 kilograms of molten sodium, releasing toxic fumes and damaging the plant; plant managers tried to cover up the accident, but covertly recorded videos were leaked to the press; there followed fourteen years of repairs and redesigns of safety measures and attempts to rebuild public trust by Monju’s operator

U.S. Navy interested in laser warfare
A big attraction of the free-electron laser (FEL) is the ability to adjust its output wavelength to improve transmission through the thick, moist air at sea; other laser weapons emit at fixed wavelengths; also, the laser is electrically powered, so it can recharge quickly, potentially allowing for repeat bursts of fire

Aussie company creates the world's first electronic underpants
More smart garments are coming to market; the latest addition: electronic underpants able to send text messages if the wearer became incontinent; this piece of clothing is aimed at the old and infirm, but clothes embedded with sensing and transmission devices will be of benefit to soldiers and first responders, measuring the wearer’s vital signs to alert medical teams in the event of injury

Synthesized polymer neutralizes both biological and chemical weapons
Biological tissues to respond rapidly and appropriately to changing environments; this logic was applied by University of Pittsburgh researchers: they have synthesized a single, multifunctional polymer material that can decontaminate both biological and chemical toxins

Researchers say a global database is needed to identify victims of mass disasters
Hundreds of thousands of people may die in natural disasters such as the Asian tsunami or the Haiti earthquake; many of the bodies of victims are never recovered because of collapsed buildings, mud slides, and more; but there are difficulties even with the recovered bodies: many of them cannot be identified and, often, entire families are killed, leaving no one behind to identify the remains; researchers say that forensic anthropology may be of help here

Premier IT technology show offers glimpse at intense rivalry among manufacturers of new gadgets
Terrorists and criminals equip themselves with the latest technology, and law enforcement must keep pace; the Federal Office Systems Exposition, a major information technology event which opened on Tuesday and closes today, shows that the future is intense in the evolving cyberspace rivalry among manufacturers and battles against crime and terrorist threats; a balanced view offered by speakers on different panels suggested that for every device displayed to counter crime and defeat terrorism there would be risk of new products falling into the wrong hands and challenging the main concepts behind the invention

DARPA wants to use ISO containers for operational flexibility, self-building floating bases
The likely tasks for navies today include humanitarian assistance and disaster relief or “maritime domain awareness and interdiction operations” — that is, detecting and stopping such activities as piracy and smuggling of weapons, drugs, sanctions-busting cargoes; traditional naval methods call for large numbers of scarce, expensive, specialized warships which may not always be much use for such missions; DARPA looks into using ISO containers and intermodal transport system to deliver flexible operational capability from unmodified commercial containerships

Korean scientists develop fast, accurate pathogen detection sensor
On average 540 million people become sick with harmful bacteria every year with fifteen million losing their lives to infectious disease around the world; the key to fighting infectious disease is for doctors to determine quickly what kind of pathogen or infectious agents have entered the body and sidestepped the natural immune system

Infrared Thermal Detection System is a fast, effective fever screening tool during pandemics
In the age of globalization, infectious diseases can rapidly spread worldwide and infect many populations; a technology which would allow healthcare professionals quickly to screen large numbers of patients with speed and accuracy and implement relevant measures to prevent further disease transmission would be very helpful; University of Nebraska researchers offer such a technology

The long view
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.
Falling Space Debris: How High Is the Risk I'll Get Hit?
An International Space Station battery fell back to Earth and, luckily, splashed down harmlessly in the Atlantic. Should we have worried? Space debris reenters our atmosphere every week.
Testing Cutting-Edge Counter-Drone Technology
Drones have many positive applications, bad actors can use them for nefarious purposes. Two recent field demonstrations brought government, academia, and industry together to evaluate innovative counter-unmanned aircraft systems.
Strengthening the Grid’s ‘Backbone’ with Hydropower
Argonne-led studies investigate how hydropower could help add more clean energy to the grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.
The Tech Apocalypse Panic is Driven by AI Boosters, Military Tacticians, and Movies
From popular films like a War Games or The Terminator to a U.S. State Department-commissioned report on the security risk of weaponized AI, there has been a tremendous amount of hand wringing and nervousness about how so-called artificial intelligence might end up destroying the world. There is one easy way to avoid a lot of this and prevent a self-inflicted doomsday: don’t give computers the capability to launch devastating weapons.
