New methods might drastically reduce the costs of investigating polluted sites
In Europe there are over 20,000 complex and large contaminated areas. These so-called megasites threaten scarce land and water resources, create environmental and health risks, and result in economic and social costs; new methods may allow polluted sites to be investigated and monitored long term at significantly reduced costs

NRC sees no evidence of bad security practices at Michigan nuclear plant
The Nuclear Regulatory Committee (NRC) released information last week about a leak earlier this summer at the Palisades plant near South Haven, Michigan; the plant has been mired in controversy this year, as at least three water leaks have occurred in the past several months, and the plant has one of the worst safety ratings in the United States

Environmentalists concerned about earthquakes tests near California nuclear plant
The Pacific Gas and Electric Company (PG&E) wants to use air guns to emit strong sound waves into a large near-shore area which includes parts of marine reserves; the purpose: creating three dimensional maps of fault zones near its Diablo Canyon nuclear plant in California; the plans have federal and state officials concerned about marine life and public safety

Dallas area earthquakes were caused by fracking: geophysicists
Three earthquakes that hit a Dallas suburb last week could be connected to fracking operations, according to a local geophysicist who studies earthquakes in the region; the earthquakes were considered minor, with the biggest one registered at a 3.4 on the Richter scale; no injuries were reported despite many emergency calls

CO2 emissions as a result of economic growth, decline not symmetrical
Estimating the trajectory of CO2 emissions, an important part of planning for climate change mitigation and adaptation, depends in part on understanding how these emissions are influenced by the economy; new study finds that in years when GDP per capita shrinks, CO2 emissions per capita do not decline in equal proportion to the amount by which they increase with economic growth

Smart robots to advance science, perform rescue missions
Researchers see a day in the not-so-distant future when intelligent robots will be working alongside humans on a wide range of important tasks from advancing science, to performing deep sea rescues, to monitoring our natural habitats; it is a bold leap from the pre-programmed factory robots and remote-controlled drones we are most familiar with today

April 2012 Indian Ocean earthquake indicate s that a new tectonic plate is being born
The 11 April 2012 8.7 magnitude earthquake in the Indian Ocean, unlike its 2004 predecessor, did very little damage; it began at one fault, and when it reached an intersecting fault, it ruptured; in total, four different faults were ruptured over the course of 150 seconds; when earthquakes spread to connecting faults, the rupture rips along faults that branch away from the initial fault like branches of a river; the April 2012 earthquakes took a very different course, running along grid-like patterns and making 90 degree turns; the weird rupture pattern reflects the fact that the region is giving birth to a new tectonic plate

Boarding gate with built-in explosives detection speeds up airport security checks
Japanese researchers have developed a boarding gate with built-in explosives detection equipment; the gate collects minute particles which have affixed themselves to IC cards or portable devices used as boarding passes, and can detect within one or two seconds the presence of explosive compounds using internalized equipment; the developers say the gate allows the inspection of 1,200 passengers per hour

China’s infrastructure is failing owing to sub-standard materials, corruption, and lax regulation
Shoddy infrastructure in China has put people in danger time and time again; many of the infrastructure issues in China stem from the government’s focus on quantity over quality, as well as making sure that as many people are employed as possible for a project, rather than using the latest construction technology; sub-standard materials, corruption, and lax regulation only exacerbate the problem

City of Ottawa sits atop soft soil, a geologic features which amplifies seismic waves
Roughly 20 percent of the Ottawa area is built on bedrock, while the remaining area contains unconsolidated surface deposits; this is not good news for city planners – and dwellers – because soft soil amplifies seismic waves, resulting in stronger ground motion than for sites built over bedrock

Innovative, “complete” solution for oil-spill cleanup
Corncobs, straw, and other absorbents used to clean up oil spills can hold only about five times their own weight and pick up water, as well as oil; scientists describe what may be a “complete solution” to cleaning up oil spills — a superabsorbent material that sops up forty times its own weight in oil and then can be shipped to an oil refinery and processed to recover the oil

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.

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.
