K-State says its security studies program leads nation
Kansas State University is currently the only university in the United States to offer a full Ph.D. in security studies, a hybrid of political science and history; the director of the security studies program says that in comparison to a homeland security master’s program, K-State’s security studies Ph.D. has much more of a focus on the phenomena that arise during international events; in a homeland security master’s program, there is more of a focus on domestic policy

Obama to pare down list of export-controlled technologies
For many years, academic institutions and businesses in the United States have complained about the long list of technologies that the U.S. government considers too sensitive to export without a license; last week, President Obama announced that administration would pare down the list of export-controlled item; businesses and universities are happy, but some in the arms-control community are not happy

IDF shows Hezbollah removing arms from exploded home
One lesson both Hezbollah and Hamas have drawn from their recent military encounters with Israel — Hezbollah in July-August 2006, Hamas in December 2008-January 2009 — is that both would benefit from increasing even more the use of the Shi’a population in southern Lebanon (Hezbollah) and the Palestinian population in the Gaza Strip (Hamas) as human shields against the Israeli military; hiding weapons and explosives in residential buildings, however, increases the number of deadly accident, as the one which occurred in Lebanese village of Shehabiyeh last Friday

Germany to extend life of nuclear reactors
Germany said on Monday that it would extend the life of the country’s 17 nuclear reactors by twelve years on average — the lives of older plants will be extended by eight years and those of newer ones by fourteen years; Chancellor Angela Merkel’s predecessor Gerhard Schroeder had decided to mothball the reactors by around 2020, but Merkel said the extension was necessary to allow more time for renewable energy to become cost effective

Technical problems grounds homemade Danish space rocket
The launch of the first homemade rocket into space failed Sunday owing to technical difficulties; the two Danish inventors who used private funds to develop the 9-meter, 1.6-ton prototype hope to send a person into space within three or four years, which would make Denmark only the fourth nation to do so

Laser-powered, ground-charged UAV stays aloft for hours
A UAV is only as good as its power source: if the drone cannot stay over target for long periods of time and must return to base to refuel, this not only adds to the costs of operating the drone but it also degrade its intelligence gathering capabilities; Seattle-based company demonstrates that it can use a laser beam to charge the UAV’s photovoltaic cells, generating enough power to keep the drone in the air for hours; the company has bigger plans for extending flight duration of military craft — and much more: in the longer term, it envisions lasers powering remote ground-based sensors, delivering power to forward military bases, or supplying emergency power during disasters

Self-learning robots to be used in earthquake, disaster rescue missions
Rescue robots capable of understanding the changing and unpredictable environment of disaster scenarios may one day be deployed to search for survivors in the aftermath of earthquakes; a robot equipped with a newly developed software, for example, would be able to recognize how something such as a stick could be used as a tool to push an object through an area too small for the robot to go into

Small thorium reactors could lead to fossil-fuel-free world within five years
An argument is made that nuclear reactors which use thorium as an accelerator (hence the technical name: Accelerator Driven Thorium Reactors, or ADTR) could lead to fossil-fuel-free world within five years; thorium is an abundant mineral deposit, with 3 to 5 times more thorium in the world than uranium; more importantly, virtually all of the thorium mined can be used as fuel compared to only 0.7 percent of the uranium recovered in its natural state, this means, in energy terms, that one ton of thorium mined is equivalent to 200 tons of uranium mined, which is equivalent to 3.5 million tons of mined coal; ADTRs also enjoy proliferation resistance advantages compared to other reactor systems

New portal to serve as a forum for the Arab world's scientific community
The Arab world has a rich and impressive history of scientific inquiry, and during the Golden Age of science Arab scientists contributed great discoveries and inventions such as algebra, optics, medicine, and many others; indeed, for more than 500 years Arabic was the language of science; for a variety of historical and political reasons, the Arab world lost the position of scientific preeminence it had enjoyed, but the potential of the Arab world’s contribution to science has not disappeared, and the prestigious journal Nature has recognized this fact by launching a new portal, Nature Middle East

Brain study: Reading Arabic is not easy
Brain researchers find that because of the complexity of Arabic script — for example, the number and location of dots is critical in order to differentiate between letters — children face a “high perceptual load” when trying to acquire the language; as a result, the right side of the brain, which is involved in the reading process for other languages — say, English and Hebrew — is not involved in reading Arabic; the native Arabic-speaking child is thus faced with more of a challenge, requiring more practice and particular pedagogic effort

Seafood stewardship questionable: experts
The world’s most established fisheries certifier — the Marine Stewardship Council (MSC) — is failing on its promises as rapidly as it gains prominence, according the world’s leading fisheries experts; “The MSC is supposed to be a solution, but a lot of what they do has turned against biology in favor of bureaucracy,” says one expert

Need for digital security spurs growth of cyber security field
The growing need for digital security has made the shortage of cyber security professionals in the United States even more apparent, and the U.S. government is now engaged in a campaign to train, hire, and retain thousands of cyber professionals; the private sector is doing its share, too: Raytheon initiated the MathMovesU program in 2005, to inspire middle school students to consider math, science, and engineering education and careers; Raytheon awards more than $2 million annually in scholarships and grants to students, teachers, and schools nationwide

Dramatic climate change is unpredictable
Scientists examine two models to explain climate change; one scenario is like a seesaw that has tipped to one side; if sufficient weight is placed on the other side the seesaw will tip — the climate will change from one state to another (an ice age, or warmer climate as is the case today); in the other model, the climate is like a ball in a trench, which represents one climate state; the ball is continuously pushed by chaos-dynamical fluctuations, and the turmoil in the climate system may finally push the ball over into the other trench, which represents a different climate state

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.
