Pasadena, CA—Galaxies that formed just 2 to 3 billion years after the Big Bang are unusually hot and glow with light from surprising elements, like nickel, according to new work led by Carnegie’s Gwen Rudie and Northwestern University’s Allison Strom. Studying “teenage galaxies” from the ancient universe can teach scientists about how these massive systems of stars mature and evolve. Their findings, published in The Astrophysical Journal Letters, are part of the CECILIA (Chemical Evolution Constrained using Ionized Lines in Interstellar Aurorae) ...

When the COVID-19 pandemic spread across the United States, healthcare workers faced new demands, childcare and grocery store workers became essential workers, businesses shut down, and churches and school doors closed. The pandemic also arrived amidst protests over police violence. Deep partisan divisions and record natural disasters amplified these challenges. The national government offered new funding for businesses and individuals and public health guidance, and local governments issued guidelines for gathering in public.  Litigating the Pandemic (University of Pennsylvania Press, 2023), a new book by Susan Sterett, professor ...

Treating cancer is becoming increasingly complex, but also offers more and more possibilities. After all, the better a tumor’s biology and genetic features are understood, the more treatment approaches there are. To be able to offer patients personalized therapies tailored to their disease, laborious and time-consuming analysis and interpretation of various data is required. Researchers at Charité – Universitätsmedizin Berlin and Humboldt-Universität zu Berlin have now studied whether generative artificial intelligence ...

New Haven, Conn. — A Yale-led analysis of the genomes of more than 1 million people has shed light on the underlying biology of cannabis use disorder and its links to psychiatric disorders, abuse of other substances such as tobacco, and possibly even an elevated risk of developing lung cancer. For the study, researchers examined a genome-wide set of genetic variants in individuals from multiple ancestry groups enrolled in the U.S. Department of Veterans Affairs’ Million Veteran Program, one of the world’s largest genetic databases, and ...

Young people may be more susceptible to the effects of the risk factors for developing atherosclerosis. According to a study carried out at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), younger people are especially vulnerable to the damaging effects of elevated blood cholesterol and hypertension, two of the major modifiable cardiovascular risk factors. These findings, published in the Journal of the American College of Cardiology, underline the need to implement aggressive control of cardiovascular risk factors at younger ages, requiring a change in primary prevention strategies to include “surveillance of subclinical atherosclerosis ...

Recent advancements in generative artificial intelligence (AI) have showcased its potential in a wide range of creative activities such as to produce works of art, compose symphonies, and even draft legal texts, slide presentations or the like. These developments have raised concerns that AI will outperform humans in creativity tasks and make knowledge workers redundant. These comments are most recently underlined by a Fortune article entitled ‘Elon Musk says AI will create a future where ‘no job is needed’: ‘The AI will be able to do everything’. In ...

A team led by researchers at Weill Cornell Medicine has used an AI-based approach to uncover underlying patterns among the conditions in which people are born, grow, live, work, and age, termed social determinants of health (SDoH), and then linked each pattern to children’s health outcomes. Compared with traditional approaches, the strategy, in principle, provides a more objective and comprehensive picture of potential social factors that affect child health, which in turn, can enable better targeted interventions. As reported Oct. 16 in JAMA Pediatrics, the researchers analyzed data on more than 10,500 American children, in communities across 17 U.S. ...

RICHLAND, Wash.—Can AI be trusted? The question pops up wherever AI is used or discussed—which, these days, is everywhere.   It’s a question that even some AI systems ask themselves.   Many machine-learning systems create what experts call a “confidence score,” a value that reflects how confident the system is in its decisions. A low score tells the human user that there is some uncertainty about the recommendation; a high score indicates to the human user that the system, at least, is quite sure of its decisions. Savvy humans know to check the confidence score when ...

Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results of the research have been published in the prestigious journal “Optica”. This discovery has implications for the study of light-matter interactions and represents a step towards the observation of a peculiar phenomenon known as a quantum backflow. “Imagine that you are throwing a tennis ball. The ball starts moving forward with positive momentum. If the ball doesn’t hit an obstacle, you are unlikely to expect it to suddenly ...

A team at the Medical University of South Carolina and Cincinnati Children’s has developed a sophisticated model for studying the diseased colon that could lead to the development of personalized treatments for colon-related diseases, such as cancer and inflammatory bowel disease (IBD). The researchers report their findings in the Nov. 2 issue of Cell Stem Cell. MUSC Hollings Cancer Center researcher Jorge Munera, Ph.D., collaborated with James Wells, Ph.D., and Daniel Kechele, Ph.D., both of Cincinnati Children’s, to grow miniature human colons complete with an immune system in the lab. This model improves upon existing organoids, or mini ...

Mammals usually mate via penetrative sex, but researchers report November 20 in the journal Current Biology that a species of bat, the serotine bat, (Eptesicus serotinus) mates without penetration. This is the first time non-penetrative sex has been documented in a mammal. The bats’ penises are around seven times longer than their partners’ vaginas and have a “heart-shaped” head that is seven times wider than the vaginal opening. Both the penises’ size and shape would make penetration post-erection impossible, and the researchers show that, rather than functioning as a penetrative ...

Cambridge scientists have shown that placing physical constraints on an artificially-intelligent system – in much the same way that the human brain has to develop and operate within physical and biological constraints – allows it to develop features of the brains of complex organisms in order to solve tasks. As neural systems such as the brain organise themselves and make connections, they have to balance competing demands. For example, energy and resources are needed to grow and sustain the network in physical ...

Wild caviar, a pricey delicacy made from sturgeon eggs, has been illegal for decades since poaching brought the fish to the brink of extinction. Today, legal, internationally tradeable caviar can only come from farmed sturgeon, and there are strict regulations in place to help protect the species. However, by conducting genetic and isotope analyses on caviar samples from Bulgaria, Romania, Serbia, and Ukraine—nations bordering the remaining wild sturgeon populations—a team of sturgeon experts found evidence that these regulations are actively being broken. Their results, ...

Astrophysicists say they have found an answer to why spiral galaxies like our own Milky Way are largely missing from a part of our Local Universe called the Supergalactic Plane. The Supergalactic Plane is an enormous, flattened structure extending nearly a billion light years across in which our own Milky Way galaxy is embedded. While the Plane is teeming with bright elliptical galaxies, bright disk galaxies with spiral arms are conspicuously scarce. Now an international team of researchers, co-led by Durham University, UK, and the University of Helsinki, Finland, say different distributions of elliptical and disk ...

About The Study: This study of 1,000 participants found that adults with low household income were less likely than adults with higher incomes to have a cardiologist involved in their care during a hospitalization for heart failure. These findings suggest that socioeconomic status may bias the care provided to patients hospitalized for heart failure.  Authors: Parag Goyal, M.D., M.Sc., of Weill Cornell Medicine in New York, is the corresponding author.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/  (doi:10.1001/jamanetworkopen.2023.44070) Editor’s Note: Please see the article ...

About The Study: In this study of 1.3 million children from Ontario, Canada, a slightly higher risk of autism spectrum disorder was observed in children born to individuals with infertility, which appears partly mediated by certain obstetrical and neonatal factors. To optimize child neurodevelopment, strategies should further explore these other factors in individuals with infertility, even among those not receiving fertility treatment.  Authors: Maria P. Velez, M.D., Ph.D., of Queen’s University in Kingston, Ontario, Canada, is the corresponding author.  To access the ...

According to Thailand's Ministry of Public Health, approximately 18-24 million or 30-40 percent of the Thai population carries the thalassemia gene, with moderately severe thalassemia patients requiring regular treatment, including blood transfusion and chelation therapy to remove excess iron from the blood. To facilitate greater understanding of this hereditary hemoglobinopathy, BGI Genomics released its State of Thalassemia Awareness Report. This report assesses the level of knowledge and attitudes related to the associated ...

A global study of major crops has found that farmworkers are being increasingly exposed to combinations of extreme heat and humidity during planting and harvest seasons that can make it hard for them to function. Such conditions have nearly doubled across the world since 1979, the authors report, a trend that could eventually hinder cultivation. The most affected crop is rice, the world’s number one staple, followed closely by maize. As temperatures rise, the trend has accelerated in recent years, with some regions seeing 15-day per-decade increases in extreme humid heat during ...

Young Voices Unheard: Children’s Views from Scotland and Greece on Education is a new book published by Bentham Science that attempts to explore the question of how young children view the concepts of Children’s rights. Giving children an opportunity to voice their ideas on their education is necessary, if we do not want to deprive children of their right to be consulted and their opinions to be listened to and be seriously considered when decisions are made affecting children’s lives (article 12 of the Convention). The book attempts to give a voice to children aged 5 to ...
