Simple new test combats counterfeit drugs in developing countries
The World Health Organization (WHO) estimates that at least 10 percent of the drug supply in developing countries consists of counterfeit medicines, causing thousands of deaths every year; many of the deaths occur among people who unknowingly take counterfeit antibiotics and anti-malaria medicines that do not contain the active ingredient to combat those diseases; in addition to lacking the active ingredient, counterfeit medicines may harm people by containing ingredients that are potentially toxic

Border Patrol kiosk detects liars trying to enter U.S.
The U.S. Customs and Border Protection (CBP) is using border crossing stations in Arizona to test new technology to detect liars as they attempt to enter the country; travelers are subjected to a 5-minute interview with the kiosk, while microphones monitor vocal pitch frequency and quality, an infrared camera monitors eye movement and pupil dilation, and a high definition camera monitors facial expression

New device dismantles pipe bombs safely, preserving forensic evidence
Thousands of pipe bombs are made each year, and thousands of pipe bomb threats are called into local police and FBI authorities across the country; many are false alarms, but those that are not can be deadly; dismantling a pipe bomb is tricky and serious business, and missteps during the dismantling process can produce catastrophic results

Geoengineering clouds to slow global warming
Researchers are taking a second look at the possibility of using futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight and thus counter global warming; The theory behind idea, called “marine cloud brightening,” is that adding particles, in this case sea salt, to the sky over the ocean would form large, long-living clouds

New technology combats global pandemic of drug counterfeiting
Drug counterfeiting is so common in some developing countries – in some studies, 50 percent of the drug samples from Southeast Asia have been counterfeit — that patients with serious diseases are at risk of getting a poor-quality drug instead of one with ingredients that really treat their illness

Aerospace materials for on-site building of pipes of infinite length
Concrete and steel pipes are built in short sections to fit on standard 18-wheel trucks; the heavy industrial manufacturing processes, long-distance trucking, and leak-prone joints used in steel and concrete pipe construction exact a heavy toll on the environment, not to mention bottom line; the solution: a new pipe design, consisting of a central layer of lightweight plastic honeycomb, which can be built onsite as a single section of virtually infinite length

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.”
