Web services could work with sensitive data -- without decrypting the data
A cryptographic method could allow cloud services to work with sensitive data without ever decrypting it; a novel technique could see future Web services work with sensitive data without ever being able to read it; several implementations of a mathematical proof unveiled last year will allow cryptographers to start making the proposal more practical.

Fibertect absorbent can clean Gulf oil spill's crude, holds toxic oil and mustard vapors
New material — raw cotton-carbon Fibertect — can absorb oil up to fifteen times its weight; the material can clean up crude oil and adsorb toxic polycyclic aromatic hydrocarbon vapors which sicken oil spill clean-up crew members; also, the material has been tested to successfully remediate mustard vapors such as those found from dumped munitions

Robot assembles itself, then flies
Soldiers and first responders often find themselves in situations of surveillance or search and rescue, in which they may have to figure out on the fly what size and shape surveillance or search-and-rescue robot they need; Swiss researchers develop a flying platform made up of autonomous wheeled vehicle that lock together to share the task of controlled and autonomous flight; this self-sufficient wheeled DFA has another advantage: if one of the parts of which it consists breaks, the robot can reconfigure itself or substitute in a different part

Autonomous vehicles to map battle environments
War is always accompanied by the fog of war; to pierce that fog, researchers at Cranfield University are working on developing swarms of autonomous military vehicles capable of sharing and overlapping video images to create high-resolution 3D panoramic scenes of dangerous battlefield areas

Next-generation HazMat boots made of leather
The rubber boots that emergency personnel wear when responding to situations where hazardous materials (HazMat) are present may be functional, but they are not very comfortable; with the availability of new textile materials and surface treatments, researchers are confident they can develop a comfortable — and functional — leather boot for use in both fire-fighting and HazMat operations

The consequences of new surveillance technology
Many wish for better security in public places, and support installation of new video surveillance technologies to achieve this goal; these surveillance technologies, however, have important psychological and legal implications, and four German universities cooperate in studying these implications

Plastic lasers shed light on hidden explosives
Detecting hidden explosives is a difficult task but now researchers in the United Kingdom have developed a new way of detecting them, with a laser sensor capable of detecting molecules of explosives at concentrations of 10 parts per billion (ppb) or less

New method manipulates particles for sensors, crime scene testing
Researchers develop a new tool for medical diagnostics, testing food and water for contamination, and crime-scene forensics; the technique uses a combination of light and electric fields to position droplets and tiny particles, such as bacteria, viruses, and DNA, which are contained inside the drops

U.S. military to adopt NFL's instant replay technology
U.S. Air Force drones collected roughly 1,800 hours of video a month in Iraq and Afghanistan in 2009, nearly three times as much video than in 2007; sifting through this growing mountain of information is difficult, so the military wants to use the same instant replay technology used in professional football games; after all, U.S. broadcasters handle 70,000 hours daily of video

Yarn passes in-vehicle flame test
Fire in an enclosed space, such as an aircraft, is extremely dangerous as occupants can die from smoke inhalation before there is any danger from the flames. Flame-retardant materials delay the spread of fire, but these typically contain halogenated substances that emit thick black smoke and toxic gases; new material developed which meets halogen-free flame-retardant regulations

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

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

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

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.”
