Helping coal miners escape underground disasters
Recent advances in mining research and practices have improved the safety and health of underground coal miners and extensive rescue strategies are in place, but more coordinated planning and training are needed better to prepare miners to escape in the event of a mine emergency, says a new report from the National Research Council.

Building stronger, greener concrete with biofuel byproducts
The world uses nearly seven billion cubic meters of concrete a year, making concrete the most-used industrial material after water. Even though making concrete is less energy intensive than making steel or other building materials, we use so much of it that concrete production accounts for between 3 to 8 percent of global carbon dioxide emissions.

New structure for regulation of geoengineering research needed: experts
Geoengineering, the use of human technologies to alter the Earth’s climate system — such as injecting reflective particles into the upper atmosphere to scatter incoming sunlight back to space — has emerged as a potentially promising way to mitigate the impacts of climate change. Such efforts, however, could present unforeseen new risks. This inherent tension has thwarted both scientific advances and the development of an international framework for regulating and guiding geoengineering research.

The infrastructure of asteroid-mining economy
An asteroid-mining space economy would be easier to build if there were the equivalent of a few Stuckey’s around out there. As is the case with other enterprises, a space economy will need fuel, liquids, and supplies, and these could be stored in outposts on dwarf planets like Ceres.

Stopping vehicle in their tracks -- remotely
The need to stop vehicles remotely was identified by the law enforcement community. In 2010, the characteristics of a squid’s sticky tendrils were combined with the concept of Spiderman’s super-strong webbing to create a prototype of the first remote device to stop vehicles in their tracks: the Safe, Quick, Undercarriage Immobilization Device (SQUID).

Using plants for herbal defluoridation of drinking water
A filtration system based on a medicinal herb can quickly and easily remove “fluoride” from drinking water, say researchers in India. The technology uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.

World’s first zero emission sports car is built-at-home electric car
A new partnership has developed the world’s first build at home electric race car kit, an all-electric sports car designed and engineered to support a growing demand for zero emission racing vehicles. The iRacer kit, available from £13,999, can be transformed quickly between hybrid, pure electric, or internal combustion engines.

Enabling small ships to launch and retrieve long-endurance UAVs
About 98 percent of the world’s land area lies within 900 nautical miles of ocean coastlines. Enabling small ships to launch and retrieve long-endurance UAVs on demand would greatly expand the U.S. military’s situational awareness and ability quickly and flexibly to engage in hotspots over land or water. DARPA is seeking companies to develop these systems.

Developing the next-generation of VTOL aircraft
One of the greatest challenges of the past half century for aerodynamics engineers has been how to increase the top speeds of aircraft that take off and land vertically without compromising the aircraft’s lift to power in hover or its efficiency during long-range flight. DARPA’s new VTOL X-Plane project aims to achieve higher speeds, increased efficiency, and elegant design.

Saving money and time in developing phased RF arrays
Phased radio frequency (RF) arrays use numerous small antennas to steer RF beams without mechanical movement. These electronics are invaluable for critical DoD applications such as radar, communications, and electronic warfare. These arrays, however, come with a high price tag. Current phased arrays are extremely expensive and can take many years to engineer and build.

Modified bacteria turn bio waste into fat for fuel
“Green” chemistry developed at Rice University is at the center of a new government effort to turn plant waste into fatty acids and then into fuel. A new project aims to develop a new generation of renewable energy and bio-based products from switchgrass and forestry residues and from a new hybrid of sorghum.

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.”
