Discovery of distant blazars supports rapid black hole formation in the early universe
Artist’s impression of a bright, very early active galactic nucleus discovered by Bañados and his colleagues. This has fundamental implications for the growth of black holes during the first billions of years of cosmic history. Credit: NSF/AUI/NSF NRAO/B. Saxton Astronomers have discovered a key piece of the puzzle of how supermassive black holes were able to grow so quickly in…

Earth experienced a period of massive and rapid melting after the last ice age, new research suggests
Credit: CC0 Public Domain At the end of the last global ice age, the frigid Earth reached a pre-built limit of climate change and melted into a slimy planet. The results of the Virginia Tech-led study show direct evidence of a slushy planet (also known as the “Plume World Ocean” era), when sky-high carbon dioxide concentrations sent the frozen Earth…

Paper-based sensor enables rapid cardiac diagnosis in 15 minutes
Deep learning-enhanced paper-based vertical flow assay for sensitive troponin detection using nanoparticle amplification. Credit: Ozcan Lab @UCLA In a significant advance in point-of-care medical diagnostics, a UCLA research team has introduced a deep learning-enhanced paper-based vertical flow assay (VFA) that can detect cardiac troponin I (cTnI) with high sensitivity. This innovative assay has the potential to democratize access to rapid…

Identifying the key dimensions of rapid tropical cyclone intensification
This image, taken by NOAA-21’s VIIRS (Visible Infrared Imaging Radiometer), shows Hurricane Beryl rapidly intensifying at 12:50pm AST on June 30, 2024. Credit: NASA Earth Observation Satellite Imager Mikala Garrison using VIIRS data from NASA EOSDIS LANCE, GIBS/Worldview, and the Joint Polar Satellite System (JPSS) Accurately predicting how fast tropical cyclones (TCs) will intensify is a major challenge due to…
