Alzheimer's Trigger 'Peak 1 A-beta' Found by Japan-U.S. Team

A Japan-U.S. team has identified 'Peak 1 A-beta' as the elusive seed that triggers Alzheimer's plaques, paving the way for early detection and preventative therapies. Simultaneously, researchers detected the first sugar in interstellar space, SpaceX's Starship deployed Starlinks on Flight 13, the first room-temperature quantum material was engineered, and Chang'e-6 moon rocks are rewriting the history of asteroid impacts in the solar system.

Alzheimer's trigger 'Peak 1 A-beta' found by Japan-U.S. team Researchers identified this substance in Alzheimer's patient brains, where it acts as an initiating seed for amyloid plaques. Injecting it into mice triggered the same damaging accumulation, offering a new target for drugs that could prevent the disease before symptoms begin. 1

First sugar molecule detected in interstellar space An international team detected the four-carbon sugar erythrulose in the molecular cloud G+0.693−0.027 near the galactic center using radio telescopes. The finding is the first identification of a sugar in the interstellar medium, supporting the theory that life's molecular building blocks formed in space. 2

SpaceX Starship Flight 13 successfully deploys Starlink satellites The fully-stacked Starship V3 launched from Boca Chica on July 24, placing 20 Starlink V3 satellites into orbit for the first time. Despite the Super Heavy booster failing its landing burn, the spacecraft achieved an in-space engine reignition, moving a step closer to operational orbital missions. 3 4 5

World's first room-temperature quantum material sorts light in unprecedented way LSU physicists created a gold-based quantum plasmonic metacrystal that operates at room temperature to distinguish and direct quantum light states. Reported in Nature, the material removes the need for extreme cooling in quantum technologies. 6

Chang'e-6 moon rocks challenge decades-old asteroid impact theory Analysis of farside lunar soil returned by China's mission reveals impact events spanning billions of years, with no single catastrophic spike 3.9 billion years ago. This overturns the Late Heavy Bombardment model and reshapes our understanding of Earth's early impact environment. 7

LHC oxygen collisions reveal new signs of the Big Bang's primordial matter The ALICE, ATLAS, CMS, and LHCb experiments found indications of quark–gluon plasma from colliding oxygen nuclei. This challenges the assumption that only heavy lead ions can produce the primordial soup of the early Universe. 8
