AI-Designed Universal Coronavirus Vaccine Clears Human Trial Milestone
8 sources2 min read
AI-designed universal coronavirus vaccine clears key human trial milestone University of Cambridge researchers report the first human trial of an AI-designed universal coronavirus vaccine is safe and generates broad immune responses against multiple strains, including SARS-CoV-2 and SARS. The needle-free microfluid-jet delivery could reshape pandemic preparedness. 1
Super alloy created by slow heating is twice as strong as steel Scientists from Australia, China and the US used lower temperatures and slower heating to let atoms self-organize into a defect-free nanostructure, achieving a compressive yield strength above two gigapascals. The method, published in Science, could transform aerospace and manufacturing. 2
JWST obtains first direct spectroscopy of cold exoplanet GJ 504 b Using JWST/NIRSpec, astronomers detected water, methane, carbon dioxide, ammonia, and isotopologues in the atmosphere of this directly imaged planetary-mass companion. The data reveal a metal-rich atmosphere with disequilibrium chemistry and salt clouds, hinting at planet-like formation. 3
Oxford physicists create exotic quantum cat states for error correction Using a trapped strontium ion, researchers demonstrated squeezed and trisqueezed superpositions that outperform conventional Schrödinger's cat states. The new states, published in Physical Review X, could enable bosonic quantum error correction that corrects both dephasing and photon loss. 4
Neurons routinely break their DNA to build the brain Kyoto University researchers discovered that migrating young neurons in the developing cortex suffer double-strand DNA breaks as they squeeze through tight spaces, but the damage is rapidly repaired. The Nature study reveals a normal, tolerance-based mechanism that may inform neurological conditions. 5
New immune discovery reveals CD4+ T cells attack cancer cells hiding from killer T cells Researchers at the University of Michigan and Baylor College of Medicine found that when cancer cells lose MHC class I to evade CD8+ T cells, they become vulnerable to CD4+ T cells, challenging decades of immunology dogma and opening new therapeutic avenues. 6
South African scientists decode cancer's immunity trick using Mucin-1 A team at the University of Cape Town used computer modelling to reveal how the MUC1 protein switches from protector to traitor by shortening its sugar chains, enabling tumors to hide from the immune system. The finding suggests new therapeutic targets. 7
Spanish-led Arrakihs mission approved to study dark matter from space ESA has greenlit the Arrakihs mission, a four-telescope observatory led by Spain to observe 80 galaxies and test current dark matter theories. The fast-track project aims for launch by 2030 and could upend our understanding of the universe. 8
