During a recent visit to Ohio State's campus, Columbus high school students learned about how the university’s exercise science major can prepare them for careers.
Two days, hundreds of miles and four campuses: That was the itinerary for The Ohio State University President Walter “Ted” Carter Jr. as he made stops to meet students, faculty and staff at the Lima, Mansfield, Marion and Newark campuses last week.
Compact Symmetric Objects (CSOs) have long puzzled astronomers with their unique characteristics. These active galaxies harbor supermassive black holes that emit powerful jets traveling at near-light speeds in opposite directions. However, unlike their counterparts in other galaxies, these jets remain compact, not extending out to great distances as expected. For decades, scientists presumed that CSOs were youthful entities, with their jets destined to expand over time.
New findings, published in three papers in The Astrophysical Journal, challenge this notion. The Caltech-led team, spearheaded by Anthony (Tony) Readhead, Robinson Professor of Astronomy, Emeritus, discovered that CSOs have relatively short lifespans. Through an exhaustive review of literature and observations, the team identified over 3,000 CSO candidates, confirming 64 as authentic CSOs and recognizing 15 new candidates. These objects were previously observed by the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO)’s Very Long Baseline Array (VLBA), renowned for its unparalleled resolution.
The studies, funded by NSF, NASA, Caltech, and the Max Planck Institute for Radio Astronomy in Bonn, Germany, mark a significant step forward in understanding the dynamic processes shaping our universe. Read the full Caltech release HERE and view NRAO’s scientific visualization animation HERE.

Muitas vezes, o primeiro sinal de uma doenca cardiovascular pode ser um evento importante como um ataque cardiaco, um acidente vascular cerebral ou uma parada cardiaca. Hoje, pesquisadores e medicos da Mayo Clinic estao utilizando a tecnologia da inteligencia artificial (IA) para sinalizar problemas cardiacos precocemente, aumentando as capacidades de um teste de diagnostico que existe ha mais de um seculo -- o eletrocardiograma (ECG).
A menudo, el primer signo de una enfermedad cardiovascular puede ser un evento importante como un ataque cardiaco, un derrame cerebral o un paro cardiaco. Hoy, investigadores y medicos de Mayo Clinic estan utilizando la tecnologia de inteligencia artificial (IA) para senalar los problemas cardiacos temprano, aumentando las capacidades de una prueba de diagnostico que ha existido durante mas de un siglo -- el electrocardiograma (ECG o EKG).
في الغالب، تكون أول علامة على وجود مرض في القلب والأوعية الدموية هي حدوث جلطة قلبية أو سكتة دماغية أو قلبية. في الوقت الحالي، يستخدم الباحثون والأطباء في مايو كلينك تقنية الذكاء الاصطناعي (AI) للتنبيه بوجود مشاكل قلبية في وقت مبكر، مما يعزز قدرات الفحص التشخيصي المعروف منذ أكثر من قرن - جهاز تخطيط كهربائية القلب (ECG).
