The Internet Archive is back as a read-only service after cyberattacks

The Internet Archive and Wayback Machine are back online in a limited read-only mode after an October 9 cyberattack, which included a data breach exposing 31 million records. Users can browse archived pages but cannot add new ones. Founder Brewster Kahle indicated the site might need further maintenance as recovery continues.

Early diagnosis of Alzheimer’s disease using a group self-calibrated coordinate attention network based on multimodal MRI

GSCANet, a novel neural network model, improves Alzheimer’s diagnosis by integrating structural and functional MRI data with neuropsychological features. It overcomes CNNs' limitations using a self-calibrated attention module for better spatial data capture. GSCANet achieved high classification accuracies, notably 92.81% for Alzheimer’s vs. normal controls, showing promise for multi-stage AD diagnosis and other diseases.

First coherent picture of an atomic nucleus made of quarks and gluons

Scientists have finally modeled atomic nuclei using quarks and gluons, resolving a decades-old challenge. While protons and neutrons were linked to quarks in the 1960s, it remained difficult to replicate low-energy nuclear properties. The breakthrough, involving Kraków’s Institute of Nuclear Physics, was recently published by the nCTEQ collaboration.

‘Mock asteroids’ deflected by X-rays in study that could help us protect Earth

Physicists have shown in lab tests that powerful X-ray bursts can potentially deflect asteroids. Using Sandia National Laboratories’ equipment, researchers mimicked an asteroid's movement and found X-rays could alter its trajectory, a method which could help protect Earth from larger asteroids, unlike current collision-based techniques.

Sustainable building effort reaches new heights with wooden skyscrapers

At the University of Toronto, a 14-story building is being constructed using mass timber, a sustainable method involving large, manufactured wood beams and panels that replace steel and concrete. This technique, resembling the assembly of flat-pack furniture, is becoming more common in global skylines.

Dietary Fats May Protect Against Thyroid Autoimmunity

In men, higher intake of total fat, saturated fats, monounsaturated fats (MUFAs), and polyunsaturated fats (PUFAs) is associated with a reduced risk of thyroid autoimmunity, based on data from the U.S. National Health and Nutrition Examination Survey. The study analyzed dietary fat intake and thyroid antibody levels, adjusting for factors like age, BMI, and smoking.

Researchers uncover distinct cell vulnerabilities in Alzheimer’s progression with novel multiomics approach

A study in Nature Neuroscience used advanced techniques to analyze molecular changes in the middle temporal gyrus related to Alzheimer's disease progression. Researchers identified two major disease phases and developed a pseudoprogression score to map neuropathological severity. This framework enhances the integration of findings across different studies, improving the reliability of Alzheimer's research.

Solar Cycle 25 is still in max phase, so more aurora-boosting sun storms could be coming

Increased solar activity from Solar Cycle 25, ongoing since December 2019, will likely enhance auroras over the next few months. This cycle is marked by more sunspots and solar flares, leading to coronal mass ejections (CMEs) that create geomagnetic storms, boosting auroral displays. The peak phase is expected to last another year before declining .

China launches second batch of 18 satellites for Thousand Sails megaconstellation

China launched the second group of 18 satellites for its Thousand Sails megaconstellation on October 15, using a Long March 6A rocket from the Taiyuan Satellite Launch Center. This deployment follows the first launch, which experienced issues with the upper stage that resulted in significant orbital debris. Concerns remain regarding the brightness of these satellites and their potential impact on astronomical observations .
