    Moderate magnitude 4.9 earthquake 40 km east of Laoag, Philippines

    1+ hour, 51+ min ago (414+ words) An earthquake of magnitude 4.9 occurred in the morning on Thursday, November 27th, 2025, at 11:10 am local time near Laoag, Ilocos Norte, Ilocos, Philippines, as reported by the German Research Centre for Geosciences (GFZ).According to preliminary data, the quake was located at a shallow depth of 10. km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc. In Carasi (pop. 1,600) located 11 km from the epicenter, the…...

    We may finally understand stress-induced hair loss

    1+ hour, 53+ min ago (684+ words) Alopecia areata, which causes patchy hair loss, is often preceded by stress. Scientists are starting to figure out why through animal studies. Scientists are connecting the dots between stress and hair loss, including a common condition that causes hair to fall out in large patches. High stress weighs heavily on the body " it can impact sleep, make the heart pound, and cause pains and muscle aches. It's also been tied to hair loss, such as the chronic hair-loss condition alopecia areata, in which immune cells attack hair follicles. "I've always been fascinated by how life experiences leave marks on our bodies," study co-author Ya-Chieh Hsu, a regenerative biologist at Harvard University, told Live Science in an email. "We still know surprisingly little about how stress reshapes our tissues and contributes to disease." But hair cells offer an accessible and informative…...

    Yellowstone’s tiny quakes cause burst of life below surface

    2+ hour, 33+ min ago (488+ words) The processes observed in the Yellowstone borehole may not be unique. Many regions around the world experience regular seismic activity that could similarly reshape subsurface energy supplies." Microbe communities living in rock and water systems beneath the Yellowstone Plateau Volcanic Field were influenced by a series of small earthquakes in 2021. The shaking from the seismic events allowed more resources to become available to these communities, which helped new life flourish. The findings appear in a new study published in the journal PNAS Nexus. The microbes in the study live far below the surface, where sunlight does not reach. They survive through chemical reactions that occur when water moves through rock features and reaches them, providing the microbes with energy. Earthquakes can have a big impact on these tiny communities: Shaking can break apart rock surfaces, redirect water flows, and release…...

    McLaren Resources Plans Exploration Program at Blue Quartz Gold Property, Timmins Ontario

    2+ hour, 56+ min ago (256+ words) Mr. John Heslop reports: The Blue Quartz Property is situated on geological faults associated with the Destor Porcupine Fault Zone which trends east-west within the Abitibi Greenstone Belt. The property hosts the past producing Blue Quartz Mine, the past producing Aljo Mine Shaft as well as the Lucky Ben exploration shaft, the Dunlop exploration shaft and the Clifford exploration shaft (see Property Map, Figure 2). Exploration success at ONYX Gold's Argus North Zone situated 5 km along structural trend to the south-east plus GFG Resources exploration success adjacent to the north Blue Quartz property boundary highlight the exploration potential of the Blue Quartz property.
