A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny specks of a quark-gluon plasma (QGP). Scientists believe such a substance of free quarks and gluons, the building blocks of protons and neutrons, permeated the universe a fraction of a second after the Big Bang.

The U.S. Food and Drug Administration (FDA) is banning the use of a food dye that has previously been linked to cancer in animals. McMaster University expert available to discuss the decision.
The large nerve cord running down each octopus arm is separated into segments, giving it precise control over movements and creating a spatial map of its suckers.
A little-known mouse protein disrupts cancer-causing chemical changes to genes associated with human colorectal cancer cells and potentially could be used to treat solid tumors, according to a new study from researchers at the Johns Hopkins Kimmel Cancer Center and the Chinese Academy of Sciences.
Researchers at Albert Einstein College of Medicine, Roswell Park Comprehensive Cancer Center and the Icahn School of Medicine at Mount Sinai have found that bacterial vaginosis consists of two distinct subtypes — one of which significantly increases the risk of developing chlamydia infections
Evidence from over 18,300 hours of recorded flight calls suggests songbirds may “talk†to other species as they migrate, forming social connections and — just maybe — exchanging information about the journey.
By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from the environmental influence of larger objects. The galaxies, located in the direction of NGC 300, were found to contain only very old stars, supporting the theory that events in the early Universe cut star formation short in the smallest galaxies.
Mediante la combinación de datos provenientes del telescopio Gemini Sur, ubicado en Chile, y de la investigación DECam Legacy Survey (DECaLS), que contiene un enorme catálogo de imágenes tomadas desde Cerro Tololo, un equipo de astrónomos descubrió tres galaxias enanas ultra tenues que sólo contienen estrellas muy viejas, reforzando la teorÃa sobre eventos ocurridos en el Universo primitivo que pudieron interrumpir la formación de estrellas en las galaxias más pequeñas. Las galaxias investigadas se encuentran en una región del espacio aislada de la influencia de otros objetos mayores.
We are joining the Carnegie Science in celebrating the 100th anniversary of Edwin Hubble’s discovery of galaxies existing beyond our Milky Way. He found a stellar “milepost marker†embedded in Andromeda and calculated it is outside our galaxy.
Women who were cared for by the MedStar Health D.C. Safe Babies Safe Moms program (SBSM) have better outcomes in pregnancy, delivery, and postpartum, according to a study published today in NEJM Catalyst Innovations in Care Delivery.
