Webb researchers discover lensed supernova, confirm Hubble tension
NASA’s James Webb Space Telescope’s NIRCam (Near Infrared Camera) image of the left side of galaxy cluster PLCK G165.7+67.0, also known as G165, shows the magnifying effect the foreground galaxy cluster has on the distant universe beyond. It shows. The Foreground Cluster is 3.6 billion light-years from Earth. The magnified area on the right shows the triple imaging of supernova…

Tracking microplastics: Helps researchers discover how microplastics move to improve stormwater management
Nasrin Alamdari, assistant professor of civil and environmental engineering at FAMU-FSU College of Engineering, poses next to the central pond stormwater culvert at Innovation Park in Tallahassee. Professor Alamdari studies the transport of microplastics from urban environments to water resources via stormwater runoff. Credit: Scott Holstein/FAMU-FSU College of Engineering Microplastic pollution is a serious environmental problem that harms animals and…

Geologists discover mysterious subduction zone beneath the Pacific Ocean, reshaping understanding of Earth’s interior
A map depicting the area where the ancient ocean floor was discovered. Credit: Jingchuan Wang, University of Maryland. Scientists at the University of Maryland have discovered evidence of an ancient ocean floor that sank deep into the Earth during the age of dinosaurs, casting doubt on existing theories about the Earth’s internal structure. This previously unstudied section of the ocean…

Researchers discover that extreme El Niño events cause short-term CO₂ fluctuations
Sensitivity of AGR to tropical MAT (γT) over a 25-year moving window from 1959 to 2020 (see Materials and Methods). Credit: Science Advances (2024). DOI: 10.1126/sciadv.adl6155 Recent research challenges previous assumptions about the relationship between atmospheric carbon dioxide and tropical temperatures. Between 1959 and 2011, atmospheric COâ‚‚ content responded twice as strongly to temperatures in the tropics than before. This…

Chemists discover new way to organize DNA in single-celled organisms
Conventional histone proteins form nucleosomes. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52337-y It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones – proteins that make up DNA. Now, PhD student Samuel Schwab from Leiden University has found that histones in these organisms are much more diverse than previously thought. Schwab and his colleagues describe more…

Astronomers discover new feature in distribution of exoplanets between Neptune’s deserts and savannas
Voyager 2 took this photo of Neptune in 1989. Credit: NASA Astronomers have discovered a new feature in the distribution of exoplanets: the “Neptunian Ridge.” The discovery, led by an international team including members from the University of Geneva, NCCR PlanetS, and the Centre for Astrobiology (CAB), highlights the complex dynamics within the Neptunian desert, where hot planets are almost…

Astronomers discover black hole is ‘starving’ its host galaxy
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that a supermassive black hole may be robbing its host galaxy of the fuel it needs to form new stars. Using Webb, an international team co-led by the University of Cambridge observed a galaxy roughly the same size as the Milky Way in the early universe, about 2 billion…

Astronomers discover new tidal tilt pulsator
~3.5 day portion of the TESS light curve for TIC 435850195. Credit: Jayaraman et al., 2024. Astronomers have discovered a new tidal pulsator star (TTP) by analyzing data from NASA’s Transiting Exoplanet Survey Satellite (TESS). The newly discovered pulsator star, named TIC 435850195, belongs to a rare class of pulsator stars known as triaxial TTPs. The discovery is detailed in…
