The War on US Farmers

The utter idiocy of participating in Israelโ€™s war on Iran is being driven home hard in the negative effects on Americaโ€™s ability to feed itself: US grain farmers have been plunged into their worst financial crisis in four decades as the war with Iran drives up diesel and fertilizer costs, the Financial Times reported on [โ€ฆ]

๐Ÿช A Wobbling โ€œPeanutโ€ Asteroid May Still Carry Traces of Ancient Water

NASAโ€™s Lucy mission has revealed one of the strangest small worlds ever seen up close: asteroid Donaldjohanson โ€” a young, peanut-shaped rock in the main asteroid belt that tumbles through space and still preserves chemical hints of liquid water from its distant past.

Lucy flew past Donaldjohanson on April 20, 2025, at about 30,000 mph, coming within just 650 miles of the asteroid. The encounter was meant partly as a rehearsal before Lucy reaches Jupiterโ€™s Trojan asteroids in 2027. Instead, it became a science story of its own.

Donaldjohanson does not rotate like a simple spinning rock. Data from Lucy show that it tumbles end-over-end once every 10.5 Earth days, while also wobbling around its long axis every 26.5 days โ€” more like an unstable top than a normal asteroid.

Its shape is just as unusual. Donaldjohanson is a contact binary: two lobes joined by a narrow neck, giving it a cosmic peanut-like form. Scientists think it formed about 155 million years ago, when fragments from a violent collision gently came back together under their own gravity.

Since then, sunlight has been slowly reshaping it. Through the YORP effect โ€” a tiny torque caused when sun-warmed surfaces radiate heat back into space โ€” Donaldjohansonโ€™s spin appears to have slowed by at least a factor of 10 over the last 20โ€“60 million years. As the rotation changed, loose material likely slid down its slopes, softening craters and reshaping the surface.

But the most intriguing clue came from Lucyโ€™s infrared data: iron-rich clay minerals on the surface. These minerals form in the presence of liquid water, meaning Donaldjohansonโ€™s parent body once experienced aqueous alteration. But unlike Bennu and Ryugu, which contain magnesium-rich clays suggesting longer exposure to water, Donaldjohansonโ€™s chemistry points to a much shorter episode.

๐Ÿ”น Donaldjohanson is a bilobed โ€œcontact binaryโ€ asteroid
๐Ÿ”น It tumbles on two axes, with rotation periods of 10.5 and 26.5 days
๐Ÿ”น Its current body likely formed around 155 million years ago
๐Ÿ”น Sunlight gradually slowed its spin through the YORP effect
๐Ÿ”น Iron-rich clays suggest liquid water was present โ€” but only briefly
๐Ÿ”น The flyby was also a successful rehearsal for Lucyโ€™s Trojan asteroid encounters, beginning with Eurybates in August 2027

Important caveat: this was a fast flyby, not an orbital mission or a sample return. Lucy measured the surface remotely; the asteroidโ€™s interior remains unknown.

Still, Donaldjohanson matters because it gives scientists a rare comparison point. Bennu and Ryugu are near-Earth asteroids with long migration histories. Donaldjohanson is a much younger main-belt object that stayed closer to its birthplace. Its strange shape, unstable spin, and brief water history offer a fresh clue to how small bodies evolved โ€” and how water-rich material may have moved through the early Solar System.

TIL that after the RMS Lusitania sank, the enquiry recorded that the ship had been struck by two torpedoes, as survivors reported two explosions as it was going down. However, the log of the U-Boat which attacked her was adamant that only one was fired. The source of the second explosion is unknown.

Russia continues a major military buildup in the Bryansk region of western Russia, fueling speculations that the Russian Armed Forces could potentially reopen the Chernigov front in northern Ukraine.

Belarus has ordered an unplanned nationwide military readiness check.

The public should not assume that something extraordinary is about to happen- Alexander Volfovich, Secretary of Belarusโ€™ Security Council.

๐Ÿšค ๐Ÿ‡บ๐Ÿ‡ธ ๐Ÿน Six months of engineering and systems integration with Lockheed Martin led to the first live-fire demonstration in Saildrone history.

At RIMPAC, SD-3001 launched two JAGM missiles while operating with US Navy assets.

This demonstration is the first of a series of planned integrations ahead of the launch of Saildroneโ€™s largest and most advanced USVโ€”the Saildrone Spectre. Measuring 52 meters (170 feet), the Spectre is designed to accommodate much larger, containerized mission sets and payloads. Future capabilities for this platform include the integration of the Lockheed Martin Mk 70 launcher and various towed arrays designed to support anti-submarine warfare operations.

Spectre, the first of which is under construction, will weigh around 300 tonnes with full payload, and capable of speeds of up to 30 knots. The USV features a concealed payload deck that accommodates up to five 20-foot containers or two 40-foot containers, making it well-suited to carry any number of the combat-tested effectors produced by Lockheed Martin, thereby satisfying a wide range of mission sets and operational requirements. Spectreโ€™s two variants, with or without the patented Saildrone Wing, offer optionality between near-silent transits for acoustically sensitive missions or a low profile for high-speed kinetic strikes.

The 20-meter (66-foot) Surveyor USV can operate autonomously in the worldโ€™s harshest environments, remaining on mission and on station for months at a time. The Saildrone Surveyor utilizes radar, EO/IR, ML-based detection, passive acoustics, and AIS to maintain continuous situational awareness alongside the newly integrated JAGM dual launcher.

In 2008, molecular analysis of collagen from a 68-million-year-old T. rex confirmed its closest living relative includes Gallus gallus domesticusthe(the domestic chicken). We took this living dinosaur relative and genetically manipulated them to grow faster and bigger just so we could eat them.

"Did Oliver Heaviside remove part of Maxwell's theory? Do scalar waves exist? Are there electromagnetic waves that travel without transverse electric and magnetic fields? This talk examines the origins of these claims, from Maxwell's original equations and Heaviside's vector reformulation to modern electromagnetics. This talk explores where longitudinal fields appear in real radio systems, how they differ from the "scalar waves" of popular literature, and why understanding them can improve our intuition about antennas, propagation, and energy flow."

๐Ÿ’ข Footage from the Zaporozhye direction, reportedly from the sector of Russiaโ€™s 291st Motor Rifle Regiment, offers a striking illustration of how mass Starlink availability continues to shape the battlefield: a Ukrainian fixed-wing drone appears to be carrying a Starlink terminal despite the aircraftโ€™s high probability of being lost.

Ukraine has received more than 50,000 Starlink terminals from international partners. At that scale, they can increasingly be treated as expendable communications hardware โ€” fitted even to drones with short life expectancies while replacement terminals keep UAV control, data links and battlefield communications functioning despite losses.

The advantage, therefore, is not only Starlinkโ€™s communications quality but its sheer abundance. Destroying one terminal is relatively easy; degrading a network where another can quickly replace it is considerably harder.
