Flinders University trapped polyiodides in a 'cage' using a starch-derived cyclodextrin polymer, extending the cycle life of an aqueous zinc-iodine battery beyond 60,000 cycles. The nonflammable, low-cost materials bring the technology closer to meeting the requirements of large-scale energy storage, though zinc anode corrosion and scale-up to real cells remain the next hurdles.
The Phase 3 trial of Moderna and Merck's individualized cancer vaccine (mRNA-4157/V940) combined with Keytruda achieved both RFS and DMFS in resected Stage IIB-IV melanoma. It marks a turning point since Provenge, but the tumor mutational burden barrier remains for applicability to acral lentiginous melanoma, the most common subtype among Japanese patients.
Seven months after China's export controls on Japan, this analysis breaks down a structural weakness in rare metal supply chains. By-product minerals like gallium have low production elasticity since they depend on the output of other metal refining, unlike primary minerals protected by large market size. It also reviews Japan's recycling and seabed resource countermeasures.
A team from the Max Planck Institute for the Science of Light and Harvard University used inverse-design algorithms to shrink wavelength demultiplexers, mode demultiplexers, and mirrors on silicon nitride photonic chips to as little as 1/500th the area of conventional designs, publishing the results in Nature Communications. To the researchers' knowledge, this is the first such demonstration on thick-film silicon nitride, opening a path toward integrated quantum photonics.
A research team at UMass Amherst has discovered a design flaw unique to Visa's contactless payment kernel: the expiration date is excluded from cryptographic signing. Using two off-the-shelf smartphones, they revived an expired card and successfully completed a transaction at a real store. Mastercard and Amex proved resistant, pointing to the issue as a Visa-specific implementation choice.
Hertha Metals has demonstrated magnet-grade iron at 99.95% purity using domestic US feedstock. Ahead of the 2027 US defense procurement rule, the next hurdles are breaking ground on commercial equipment and securing customer qualification.
Nanjing University and Renshine Solar achieved a certified efficiency of 22.0% in a 0.72-square-meter perovskite module. Based on accelerated tests and a three-month outdoor comparison, we examine what conditions remain before mass adoption.
A University of Adelaide research team has published a new electrochemical method in Nature Synthesis that converts urea from urine and table salt into hydrazine. Unlike the dangerous oxidant-dependent industrial process that has dominated for 120 years, the new aqueous, room-temperature method achieves more than 10 times the current density and 240 hours of stable operation.
An analysis of one year of real-world driving data from 15 EVs in Guangzhou using physics-aligned causal inference predicted that the most aggressive driving style causes roughly 2.5 times more battery capacity degradation than eco-driving. It is one of the first attempts to statistically isolate the effects of temperature and state of charge, though the figures after 1,000 cycles are model predictions, not measured values.
A hybrid material combining the light-driven proton pump of halophilic bacteria with a semiconductor nanosheet synthesized hydrogen peroxide from sunlight and air at room temperature and atmospheric pressure. Showing more than five times the production efficiency of the semiconductor alone, it opens the possibility of a distributed, decarbonized synthesis route to replace the anthraquinone process.
