ORLANDO, Fla. (May 3, 2021) - Researchers have identified a gene expressed in children with acute myeloid leukemia (AML) that could serve as a new immunotherapy treatment target, according to a new study published today in Blood Advances, a journal of the American Society of Hematology. The study, co-authored by researchers with Nemours Children's Health System, outlines the process and potential path for new immunotherapy drugs that improve survival and reduce treatment-related toxicity in children with AML.
Coronavirus (CoVs) infection in animals and humans is not new. The earliest papers in the scientific literature of coronavirus infection date to 1966. However, prior to SARS-CoV, MERS-CoV, and SARS-CoV-2, very little attention had been paid to coronaviruses.
Many miles of streams and rivers in the United States and elsewhere are polluted by toxic metals in acidic runoff draining from abandoned mining sites, and major investments have been made to clean up acid mine drainage at some sites. A new study based on long-term monitoring data from four sites in the western United States shows that cleanup efforts can allow affected streams to recover to near natural conditions within 10 to 15 years after the start of abatement work.
BOSTON -- Immunity often calls to mind the adaptive immune response, made up of antibodies and T cells that learn to fight specific pathogens after infection or vaccination. But the immune system also has an innate immune response, which uses a set number of techniques to provide a swift, non-specialized response against pathogens or support the adaptive immune response.
MINNEAPOLIS - Chronic kidney disease is when a person's kidneys progressively lose their ability to filter waste from the blood and eliminate fluids. Now a new study has found that people with reduced kidney function may have an increased risk of developing dementia. The study is published in the May 5, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Virtual care provided through telephone or videoconference has been broadly implemented in recent months because of the COVID-19 pandemic. A new analysis of published studies has examined the accuracy and reliability of virtual compared with in-person cognitive assessments for diagnosing dementia or mild cognitive impairment.
A new study published in the British Journal of Educational Technology has identified the different needs of students across primary, middle, and high school related to online learning during the COVID-19 pandemic.
For the study, investigators surveyed 1,170,769 Chinese students from the Guangdong Province of China.
The population growth of an endangered butterfly species is greatest in habitats with microclimatic variability, demonstrates a study carried out collaboratively by the Faculty of Biological and Environmental Sciences and the Helsinki Institute of Life Science of the University of Helsinki as well as the Finnish Environment Institute.

Scientists have revealed how an antibiotic of 'last resort' kills bacteria.
The findings, from Imperial College London and the University of Texas, may also reveal a potential way to make the antibiotic more powerful.
The antibiotic colistin has become a last resort treatment for infections caused by some of the world's nastiest superbugs. However, despite being discovered over 70 years ago, the process by which this antibiotic kills bacteria has, until now, been something of a mystery.
University of South Australia researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.
This enzyme, NEDD4-2, is critical for kidney health, says UniSA Centre for Cancer Biology scientist Dr Jantina Manning in a new paper published this month in Cell Death & Disease.
Pioneering neural recordings in patients with Parkinson's disease by UC San Francisco scientists lays the groundwork for personalized brain stimulation to treat Parkinson's and other neurological disorders.
Blood may seem like a simple fluid, but its chemistry is complex. When too much potassium, for instance, accumulates in the bloodstream, patients may experience deadly irregular heart rhythms.
Cardiovascular scientists at Virginia Tech's Fralin Biomedical Research Institute at VTC are studying why.
In a new study, published in Pflügers Archiv European Journal of Physiology, the research team led by Steven Poelzing, associate professor at the institute, describes how subtle changes in potassium, calcium, and sodium levels regulate heartbeats.
In the field of molecular epidemiology, the worldwide scientific community has been steadily sleuthing to solve the riddle of the early history of SARS-CoV-2. Despite recent efforts by the World Health Organization, no one to date has identified the first case of human transmission, or "patient zero" in the COVID-19 pandemic.
Finding the earliest possible case is needed to better understand how the virus may have jumped from its animal host first to infect humans as well as the history of how the SARS-CoV-2 viral genome has mutated over time and spread globally.
DALLAS, May 4, 2021 -- A meta-analysis of 14 air pollution studies from around the world found that exposure to high levels of air pollutants during childhood increases the likelihood of high blood pressure in children and adolescents, and their risk for high blood pressure as adults. The study is published in a special issue on air pollution in the Journal of the American Heart Association, an open access journal of the American Heart Association.
