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

New device to "smell" human fear
City University London’s researchers launch a project aims to develop two sensor systems that can detect the unique chemical signature of the fear pheromone, assessing the stress of an individual and interpreting it in security-critical contexts

Humanoid robots to help people in hazardous environments
Current calculations required for robots’ handling objects and avoiding collisions are based on movements in the XYZ coordinates, and are sensitive to any minor deformations in the environment, such as a flexible object that would cause the calculations to be invalid; researchers offer a new way to govern robots’ movement

Fingerprint technology beats world’s toughest tests
Among the fingerprints most difficult to identify are those of brick-layers, but a new technique developed by University of Warwick researchers did so successfully; the secret: the University of Warwick researchers consider the entire detailed pattern of each print and transform the topological pattern into a standard co-ordinate system

Israeli company shows unmanned smart-missile pack
A large box contains several vertically launched missiles and its own communications and power; it is generally light enough to be driven about by a Humvee or similar, parachuted down from a transport plane, dropped off by helicopter, tied down on the deck of a ship or barge; the missiles are launched by remote control

Mitchell Zakin revived the chemistry discipline at DARPA
Mitch Zakin —who says, “I joined DARPA because it is unfettered by conventional wisdom” — will leave the agency in 2010; he has been working on developing “the infochemistry project,” which combines the powers of chemistry and information technology

DARPA seeking to improve bio-threat detectors
The agency is requesting proposals for a device that would enable faster, more accurate detection of a broad range of biological agents; DARPA hopes to create a biosensor that would identify viral and bacterial threats, and do so using a natural first-line of defense: human antibodies

Encryption Breakthrough Lays Groundwork for Privacy-Preserving AI Models
In an era where data privacy concerns loom large, a new approach in artificial intelligence (AI) could reshape how sensitive information is processed. New AI framework enables secure neural network computation without sacrificing accuracy.
AI-Controlled Fighter Jets May Be Closer Than We Think — and Would Change the Face of Warfare
Could we be on the verge of an era where fighter jets take flight without pilots – and are controlled by artificial intelligence (AI)? US R Adm Michael Donnelly recently said that an upcoming combat jet could be the navy’s last one with a pilot in the cockpit.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
Using Liquid Air for Grid-Scale Energy Storage
New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.
Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
Autonomous Weapon Systems: No Human-in-the-Loop Required, and Other Myths Dispelled
“The United States has a strong policy on autonomy in weapon systems that simultaneously enables their development and deployment and ensures they could be used in an effective manner, meaning the systems work as intended, with the same minimal risk of accidents or errors that all weapon systems have,” Michael Horowitz writes.
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
