Beijing’s compromise of Tokyo’s classified cyber networks could prevent greater strategic coordination between Japan’s Defense Ministry and the Pentagon.

The Australian military is funding a project to grow intelligent “mini-brains” in petri dishes. The goal is to use these “DishBrains” to design better AIs — and, eventually, even combine the two, creating AIs merged with processing features of human brain cells.
By creating just the right conditions, scientists can coax stem cells into growing into “organoids,” three-dimensional tissues that resemble the structure and function of different organs — even brains.
Japanese Prime Minister Fumio Kishida warned of Russia’s nuclear threat and reaffirmed a pledge to work to make the world free of nuclear weapons in a speech marking 78 years since the atomic bomb fell on Hiroshima on Sunday. “As the only country to have experienced the horror of nuclear devastation in war, Japan will press on tirelessly with its efforts to bring about ‘a world without nuclear weapons,’” Kishida said in remarks delivered in Hiroshima, in a tribute to the victims, their families and those still suffering aftereffects of the bomb.
The magnetohydrodynamic (MHD) drive certainly sounds like something out of science fiction — using an array of magnets and electrodes, this high-tech propulsion technology promises to silently propel a craft through the water without any moving parts. As long as you can provide it with a constant supply of electricity, anyway.
Of course, as is often the case, the devil is in the details. Even with the obvious scientific and military applications of such a propulsion unit, scaling MHD technology up has proven difficult. But as [Jay Bowles] of Plasma Channel shows in his latest video, that doesn’t mean you can’t experiment with the concept at home. Even better, getting verifiable results is much easier than you’d think.
While [Jay] usually won’t even get out of bed for less than a dozen kilovolts, a standard bench supply is all you need to power your very own MHD. He ran his experiential drive at a maximum of 25 VDC/9 A, but he was getting results with just 5 VDC/1.5 A. Beyond that, it’s just a matter of cutting some electrodes out of metal stock and placing them on either side of the most powerful magnets you can get your hands on. Add in a 3D-printed structure and some pieces of acrylic, and you’re halfway to a bathtub rendition of The Hunt for Red October.
They finally reached ignition again last week, according to a statement Sunday from the lab. The news was first reported by the Financial Times.
“In an experiment conducted on July 30, we repeated ignition,” the statement read. “Analysis of those results is underway. As is our standard practice, we plan on reporting those results at upcoming scientific conferences and in peer-reviewed publications.”
Unlike fission, the process used in current nuclear power plants, fusion involves smashing atoms together instead of splitting them apart. It theoretically can supply carbon-free energy without long-lasting radioactive waste. But generations of scientists have struggled to master it in a controlled reaction, even though it has been the power source of nuclear weapons for decades.
The US dispatched four navy warships as well as a reconnaissance airplane after multiple Chinese and Russian military vessels carried out a joint naval patrol near Alaska last week.
The combined naval patrol, which the Wall Street Journal first reported, appeared to be the largest such flotilla to approach US territory, according to experts that spoke to the outlet.
A number of military leaders around the world have expressed concerns to US officials over the dominance and control of SpaceX founder Elon Musk over satellite internet, according to a new report.
Over the past decade Musk’s SpaceX has changed the launch industry with its reusable Falcon 9 rocket. The company has pressed this advantage to establish itself as the leading player in satellite internet through Starlink.
New interference radar functions employed by a team of researchers from Chapman University and other institutions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and many other domains of radar applications.
This first proof-of-principle experiment opens a new area of research with many possible applications that can be disruptive to the multi-billion dollar radar industry. There are many new avenues to pursue both in theory and experiment.
The discovery addresses a nine decades-old problem that requires scientists and engineers to sacrifice detail and resolution for observation distance—underwater, underground, and in the air. The previous bound limited the distance estimated between objects to be one quarter of the wavelength of radio waves; this technology improves the distance resolution between objects using radar waves.
BEIJING (AP) — China imposed restrictions Monday on exports of long-range civilian drones, citing Russia’s war in Ukraine and concern that drones might be converted to military use.
Chinese leader Xi Jinping’s government is friendly with Moscow but says it is neutral in the 17-month-old war. It has been stung by reports that both sides might be using Chinese-made drones for reconnaissance and possibly attacks.
Export controls will take effect Tuesday to prevent use of drones for “non-peaceful purposes,” the Ministry of Commerce said in a statement. It said some drone exports still will be allowed.
Arms reduction is a noble goal, but it’s not one being pursued by some of the worst regimes in the world. The late George Shultz, former secretary of state for Ronald Reagan and a Cold Warrior, once advised against proliferating nuclear weapons. He quipped that “proliferation begets proliferation,” which the arms control lobby has used for decades to prevent the U.S. government from developing nukes.
