A team at the University of Science and Technology of China has developed an 87Rb atomic magnetometer with a 7cm³ sensor head and under 5W power consumption. Its 10pT/√Hz sensitivity falls short of commercial devices, but it tracks field changes of 25,200nT per second and auto-relocks in under one second. The subway station test demonstrated resilience to disturbances, not submarine detection capability.
A US research team raised the capacity and voltage of a lithium-sulfur battery using a three-electron sulfur reaction. We compare the electrode-level figures, the calculated cell-level value, and the pouch-cell durability test to see what practical use still requires.
US rare earth mine production rose to 51,000 tons in 2025, but USGS data show net import dependency for compounds and metals jumped from 53% to 67%. The bottleneck lies in separation and refining capacity, not mining—a structural gap that could keep China dependence intact into the 2030s.
ASM has unveiled a carbon film that fills trenches and flattens the surface in a single PECVD process, and says early production adoption has begun. We trace its development since 2023 and look at the performance figures that remain undisclosed.
A Stanford-led paper in Nature Neuroscience showed that forebrain/midbrain progenitors and hindbrain progenitors arise in parallel very early in embryonic development. But the claim that the brain is "two separate organs" doesn't appear in the paper's abstract—and within five days of publication, media coverage ranged from flat assertion to outright pushback.
Penn State reports a MEMS mirror that combines two-axis scanning and focus adjustment in one device. Looking closely at a 63 mm scanning-pattern experiment and a separate 5 mm microscope experiment reveals what was actually measured—and what challenges remain before practical use.
Researchers argue in a commentary that AI extinction scenarios run into physical constraints. We check the 27-reader mammography experiment they cite against the original paper and separate the risk of following wrong advice from the concern about long-term decline in judgment.
APL is working on a portable NMR device to identify chemical and biological threats in the field. It has demonstrated magnetic field measurement but not molecular identification in liquids. We compare the announcement with earlier research to see what still needs validating.
A Stanford research team used a superconducting qubit to achieve real-time observation of quantum jumps as single phonons are lost inside a microscopic mechanical resonator. This article examines the statistics from roughly 8,447 measurement trajectories showing discontinuous transitions, along with the measurement backaction challenges that remain on the path toward quantum memory.
TBC and AWS announced plans to commercialize a video AI model informed by cultured neurons. We separate the public Oasis experiments from the commercial model's performance claims, looking at how it works and how it was measured.
