Adding bellyflaps to blended-wing aircraft increase their manoeuvrability
Blended-wing aircraft generate less drag, are quieter, and use far less fuel; they are also less maneuverable because the aerodynamic surfaces that control an aircraft’s pitch are located closer to the aircraft’s center of gravity than those on a conventional aircraft; the solution, adding bellyflaps

New, quick test for dehydration
In-the-field exertions by soldiers and first responders may cause dehydration, the result of fluid loss of only a few percent of body weight; Philips offers a transducer which measures how much the skin deforms when sucked — a clear indication of dehydration

Existing biotechnology would save energy, cut CO2 by 100 percent
A major — and surprisingly overlooked — contribution to reducing greenhouse gasses: New analysis shows that use of existing biotechnology in the production of bulk chemicals could reduce consumption of nonrenewable energy and carbon emissions by 100 percent

Innovative nozzle protects firefighters against flashover
Firefighters face not only the immediate fire, but also the risk of flashover — this is when fumes seeping out of walls and furniture get so hot they spontaneously ignite; innovative nozzle from an Austrian company addresses this risk

Shape-memory rubber developed
University of Rochester researchers develop shape-memory rubber which allows designers to make products as diverse as biomedical implants, conformal face-masks, self-sealing sutures, and “smart” labels; material made from shape-memory polymers, once stretched into a new shape, stay in that form until heated, at which time they revert to their initial shape

Enjoying the benefits of GPS technology without giving up on privacy
The proliferation of location-based services raises the specter of an Orwellian Big Brother society in which a citizen’s every move is monitored and tracked; two computer scientists offer a way to enjoy the benefits of location-based services, while avoiding the more sinister aspects of the technology

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.
