New generator for wind turbines
To connect to the National Grid, large turbines often use a doubly fed induction generator (DFIG) system comprising brushes and slip rings; these require regular maintenance which can be difficult to carry out, particularly offshore or in poor weather conditions; U.K. researchers offer solution

New acoustic system locates snipers with accuracy
System detects the sound of an initial gunshot then the shockwave from the muzzle of the weapon being fired; since sound travels faster than a shockwave, the system is able to pinpoint the position of the attacker

Breakthrough: Dramatic increase in thermoelectric efficiency achieved
Two hundred years ago scientists discovered the thermoelectric effect: Certain materials can convert heat into electricity and vice versa; trouble is, most materials which conduct electricity also conduct heat, so their temperature equalizes quickly; until now: Boston College, MIT researchers solve this vexing problem

Cat's eyes locate things underwater
A new underwater cat’s eye can reflect back a tuned signal, revealing its location, to existing sonar systems; new device does not use batteries — and it does rely on toxic chlorofluorocarbons (CFCs)

Ambient blue light resets tired workers' body clocks
Tedious work during the “wrong” hours of the body’s biological clock — think truckers who drive through the night, or security officers monitoring CCTV screens during the graveyard shift — often leads to drowsiness; falling asleep behind the wheel or in front of a security monitoring screen can lead to catastrophes; researchers develop a way to “fool” the brain to think it is morning

UCSD researchers develop tiny explosive sensor
Sensor works by monitoring the variability of electrical conductivity through thin films of metal phthalocyanines; “The detection capability of this tiny electronic sensor is comparable to current instruments, which are large, bulky and cost thousands of dollars each,” says William Trogler, UCSD professor of chemistry and biochemistry

The long view
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.”
A Brief History of Federal Funding for Basic Science
Biomedical science in the United States is at a crossroads. For 75 years, the federal government has partnered with academic institutions, fueling discoveries that have transformed medicine and saved lives. Recent moves by the Trump administration — including funding cuts and proposed changes to how research support is allocated — now threaten this legacy.
Bookshelf: Preserving the U.S. Technological Republic
The United States since its founding has always been a technological republic, one whose place in the world has been made possible and advanced by its capacity for innovation. But our present advantage cannot be taken for granted.
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.
Ukraine Drone Strikes on Russian Airbase Reveal Any Country Is Vulnerable to the Same Kind of Attack
Air defense systems are built on the assumption that threats come from above and from beyond national borders. But Ukraine’s coordinated drone strike on 1 June on five airbases deep inside Russian territory exposed what happens when states are attacked from below and from within. In low-level airspace, visibility drops, responsibility fragments, and detection tools lose their edge. Drones arrive unannounced, response times lag, coordination breaks.
Shots to the Dome—Why We Can’t Model US Missile Defense on Israel’s “Iron Dome”
Starting an arms race where the costs are stacked against you at a time when debt-to-GDP is approaching an all-time high seems reckless. All in all, the idea behind Golden Dome is still quite undercooked.
