New high-energy drop-in fuel clears first rotating detonation rocket engine test

A rocket fuel that could slot right into existing engines without a single hardware change is now being put to the test. CycloKinetics and Venus Aerospace are evaluating a new propellant called CycloRP inside a rotating detonation rocket engine, a cutting-edge design that uses controlled detonation waves to squeeze more energy out of combustion.

The first phase, completed in July 2026, confirmed that CycloRP can successfully detonate inside the engine, a critical hurdle given the extreme pressures involved.

Next comes the harder question: can it keep engines cool? Engineers plan to circulate the fuel through engine components before ignition, testing whether it manages heat as effectively as conventional propellants.

Mukund Karanjikar, CEO of CycloKinetics, says the fuel was "designed as a direct replacement for conventional rocket propellants," with domestic production as an added advantage.

Backed by the U.S. Air Force Research Laboratory, the program expects to deliver a full technical assessment in early 2027. [Read More]

US nuclear fusion reactor prevents plasma instability 200 milliseconds in advance (4m read)

A new AI platform called PACMAN successfully stabilized a nuclear fusion reactor in live tests, predicting dangerous plasma instability 200 milliseconds before it formed, far faster than traditional systems. Running every 20 milliseconds, it controlled heating systems and adjusted reactor settings automatically, potentially making fusion reactors safer and more practical for future commercial use.

86 MW solar project pairs lithium-ion and zinc batteries for round-the-clock power (4m read)

A new solar-and-storage project in West Virginia will combine 86 MW of solar power with 380 MWh of batteries to supply Google's data centers with around-the-clock clean electricity. MN8 Energy, Eos Energy, and Google are pairing lithium-ion batteries with a 10-hour zinc-based system on a former coal mine site, representing up to $350 million in investment and 200 construction jobs, with operations starting between 2028 and 2030.

Four BWRX-300 small reactors target 1.2 GW of nuclear power by the mid-2030s (4m read)

Sweden is building four BWRX-300 small modular reactors targeting 1.2 GW of power by the mid-2030s. Studsvik, GE Vernova Hitachi, and Samsung C&T are partnering on the project, using a repeatable four-unit model to reduce costs and build a Swedish nuclear supply chain.

New heating trick makes hydrogen and graphite from methane 10x more efficiently (4m read)

Stanford researchers have developed a way to produce hydrogen from methane 10 times more efficiently by placing a burner inside the reactor instead of heating it from outside. This internal heating method burns a small amount of hydrogen, generates the needed heat, and emits mostly water vapor. A bonus discovery: the solid carbon byproduct is graphite, a battery material the US currently imports.

Ultra-lightweight thin-film tandem solar cells set new world record at 26.7% efficiency (4m read)

South Korea's Korea Institute of Energy Research set a new world record for perovskite/CIGS tandem solar cells, achieving a certified efficiency of 26.7%, verified by Germany's Fraunhofer Institute. These thin, flexible cells stack two light-absorbing layers to maximize power without added weight, making them ideal for satellites and buildings.

Researchers unveil floating titanium lattice 70% stronger than steel at equal density (4m read)

Researchers at RMIT University have developed a 3D-printed titanium lattice structure filled with polyurethane foam that floats even when damaged. The foam fills only the hollow titanium struts, letting water flow through the larger openings while keeping the structure buoyant. At equal density, it is 70% stronger than stainless steel and lost less than 1% of its strength after seawater exposure, pointing to promising marine infrastructure applications.

'There is no conflict between quantum physics and gravity': Physicists prove Einstein's 'happiest thought' holds true at quantum scales (2m read)

For the first time, physicists have measured a quantum effect predicted in 1927, confirming that Einstein's equivalence principle holds at the quantum scale. Using ultracold rubidium atoms split into two paths, one in free fall and one suspended, researchers recorded interference patterns matching theoretical predictions within 2.5%. The findings suggest no conflict between quantum mechanics and general relativity, opening doors to deeper tests involving gravity and quantum superposition.

Scientists just overturned a century-old physics assumption (5m read)

Featured Carnegie Mellon University researchers have overturned a century-old assumption about the Hall effect, a foundational physics principle used to study how materials behave electrically and magnetically. Scientists long believed the Hall effect only worked with magnetic fields applied in one direction, but the team proved it also works with fields applied in-plane. This breakthrough means a single ultrathin sensor could detect magnetic fields in multiple directions, potentially simplifying electronics, transportation systems, and medical imaging technology.

Have we finally found dark matter? (7m read)

Featured Deep beneath South Dakota's Black Hills, a detector called LUX-ZEPLIN recorded a mysterious flash of light in June 2023 that could be the first-ever sign of dark matter. The event does not match any known background noise, but it is also unusually powerful for a standard dark matter signal. Scientists remain cautious, but 700 days of additional blinded data could confirm whether this is a real discovery.

No Two People Age in the Same Way (4m read)

A major eight-year study tracked 335 women, measuring changes in 16,000 genes, revealing that aging is deeply personal at the molecular level. While some trends were universal, like weakening tumor-suppressor activity, individual gene patterns varied wildly, suggesting future medical treatments could be tailored to each person's unique aging process.

US opens 56,000-square-foot factory to build hydrogen-powered drones at scale (4m read)

Heven AeroTech opened a 56,000-square-foot drone factory in Winchester, Virginia, built in just 90 days, to manufacture its Z1 hydrogen-powered drone for defense partners. The facility anchors a planned coast-to-coast production network, designed to scale hydrogen drone manufacturing beyond prototypes, and is expected to create hundreds of jobs nationwide.
