Iran tested advanced nuclear warhead design
The “two-point implosion” is one of the most guarded secrets in nuclear weapons states; yet Iranian engineers, in what Western nuclear experts describe as a breakthrough, has tested such a design, which much be described as a giant leap in acquiring nuclear weapons

New communication system to help protect soldiers in the field
The new technology will use arrays of highly specialized antennas that could be worn by combat troops to provide covert short-range person-to-person battleground communications; the technology will lead to advanced wireless systems that would enable small squads of soldiers to share real-time video, covert surveillance data and tactical information with each other via helmet-mounted visors

First winner in space elevator competition
The contest requires their machines to climb 2,953 feet (nearly 1 kilometer) up a cable slung beneath a helicopter hovering nearly a mile high; the vehicle from the Kansas City-based LaserMotive zipped up to the top in just over four minutes and immediately repeated the feat, qualifying for at least a $900,000 second-place prize

First space hotel taking bookings for 2012 opening
Space tourism is nearing, with the first space hotel set to open in 2012; the Barcelona-based company is already taking bookings; the cost of three nights (plus a two-month training course on a Caribbean island beforehand) will be $4.4 million per guest

Robot fish could monitor water quality
Michigan State University researchers develop robots that use advanced materials to swim like fish to probe underwater environments; robotic fish — perhaps schools of them operating autonomously for months — could give researchers far more precise data on aquatic conditions, and the quality — and security — of the water supply

Space elevator competition to test alternatives to rocketry
The space elevator idea envisions replacing rockets with electrically powered vehicles which would run up and down a cable anchored to a ground structure and extending thousands of miles up to a mass in geosynchronous orbit — the kind of orbit communications satellites are placed in to stay over a fixed spot on the Earth; space elevator competition being held this week in the the Mojave Desert

New technology to boost food security
A scientist in the Philippines develops a new method for keeping food fresh; brine-immersion freezing, or BIF, allows fish and meat can be stored for two to three days in styrofoam boxes without using ice, and up to six months when stored in freezers or chillers

Day of quantum communications in the theater nears
The challenges so far with free space optical links, which use fibre optics for transmission, have been the turbulence or distortions from temperature differences that cause motion or wind in the atmosphere; researchers have established an optical link without distortion in test situations at a distance of 35km in stationary and flight situations

New high-precision chemical detector to be commercialized
A start-up launched by the University of Delaware is preparing to commercialize a high-precision detector — a planar-array infrared spectrograph — that can identify biological and chemical agents in solids, liquids, and gases present at low levels in less than a second

DARPA announces a $40,000 red-balloon Network Challenge
To celebrate the Internet’s 40th anniversary, DARPA will moor ten 8-foot red weather balloons across the continental United States during the daylight hours of 5 December; the first individual — or group — to identify the location of the balloon will receive $40,000

Questions raised about Obama's smart grid funding
For the smart grid project to succeed, the business case for it needs to be widely accepted by the stakeholders involved (skeptics would say that if efficiency-mindedness was at the top of the agenda in utility boardrooms and state regulatory agencies, then no federal stimulus money would be needed to install these kinds of technologies); also: the Obama plan envisions a joint public-private smart grid expenditure of $8.1 billion — the government’s $3.4 billion is being matched by $4.7 billion in private investment; a recent analysis of what it would take to build a unified national smart grid put the tab for such a grid at $400 billion

Robotic platform helps soldiers carry heavy gear
Israel Aerospace Industries unveils robotic platform designed for ground forces; the platform, carrying up to 200kg of gear, follows the lead soldier from a distance; the soldiers control the platform by using simple commands, including “stop,” “fetch,” and “heel”

New material makes buildings more fire resistant
New material, called “liquid granite,” is fire resistant to temperatures in excess of 1,100oC; it reduces the fire risk in buildings because, unlike concrete, it does not explode at high temperatures

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.
