Blood Test Detects Knee Osteoarthritis 8 Years Before X-Rays
Duke Health researchers have developed a blood test that can predict knee osteoarthritis eight years before it is detectable by x-rays, offering a significant improvement over current diagnostic methods. This advancement could enable earlier treatment interventions, potentially altering the disease’s impact and progression.Early detection of knee osteoarthritis could lead to therapies that slow progression and
Skin Test Detects Parkinson’s and Other Synucleinopathies
Neurology > Parkinson's Disease — Cutaneous alpha-synuclein deposits may serve as a biomarker by Judy George , Deputy Managing Editor, MedPage Today March 21, 2024 Skin biopsies detected phosphorylated alpha-synuclein in a high proportion of people with Parkinson's disease and other synucleinopathies.Finding a reliable diagnostic biomarker for synucleinopathies is an urgent unmet need.Further research is
Hubble Detects Water Vapor in Atmosphere of Gliese 9827d
Using the Wide Field Camera 3 (WFC3) instrument onboard the NASA/ESA Hubble Space Telescope, astronomers have detected water vapor in the transmission spectrum of the sub-Neptune exoplanet Gliese 9827d. The water detection in the transit spectrum of Gliese 9827d makes it the first water world candidate with an atmospheric water detection consistent with a water-rich
ATCA Detects Compact Radio Source in Center of 47 Tucanae
Astronomers using CSIRO’s Australia Telescope Compact Array have captured the most detailed radio image ever seen of 47 Tucanae, the second brightest globular cluster in the night sky. Paduano et al. identified a new radio source (white square) in the center of 47 Tucanae (red circle). Image credit: Paduano et al., doi: 10.3847/1538-4357/ad0e68. 47 Tucanae
Webb Detects 3-Million-Light-Year-Long Filament of Galaxies in Early Universe
Galaxies are strung along filaments in the vast cosmic web, which also contains enormous voids. Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have discovered an early strand of this structure — a long, narrow filament of 10 galaxies that existed just 830 million years after the Big Bang. The 3 million light-year-long structure is
IXPE Detects 200-Year-Old Flare from Milky Way’s Supermassive Black Hole
The center of the Milky Way Galaxy hosts Sagittarius A*, a supermassive black hole with a mass of about 4 million solar masses that is very quiescent. Reflection of X-rays from Sagittarius A* by dense gas in the Galactic center offers a means to study its past flaring activity on timescales of hundreds and thousands of
Astronomers using the Atacama Large Millimeter Array (ALMA) have detected a rapidly growing supermassive black hole in COS-87259, a galaxy that forms stars at a rate 1,000 times that of our own Milky Way Galaxy and contains over a billion solar masses worth of interstellar dust. This Hubble image shows NGC 5033, a spiral galaxy
Dawn Detects Organics and Salts in Giant Crater on Ceres
Using the Framing Camera (FC) and the Visible and Infrared Spectrometer (VIR) aboard NASA’s Dawn spacecraft, planetary researchers have spotted bright brine residues and organics in the Urvara basin, one of the largest impact structures on the dwarf planet Ceres. The results strengthen the hypothesis that Ceres is and has been a geologically active world…
Mars rover detects carbon signature that may hint at past life source
Since 2012, NASA’s Curiosity rover has trundled across Mars, drilling into rocks and running the grit through a sophisticated onboard chemistry lab, aiming to tease out evidence for life. Today, a team of rover scientists announced an intriguing signal, one that may or may not be evidence of past life, but is, at the very…
Chandra Detects Mini-Supermassive Black Hole in Star-Forming Dwarf Galaxy
A supermassive black hole with 200,000 solar masses is located in the middle of the dwarf galaxy Markarian 462 (Mrk 462), according to new research led by Dartmouth College astrophysicists. This graphic shows X-rays that NASA’s Chandra X-ray Observatory detected from the dwarf galaxy Mrk 462. This X-ray emission (inset) is important because it reveals…
