Annapolis, MD; May 26, 2021--A new study has mounted perhaps the most intricate, detailed look ever at the diversity in structure and form of bees, offering new insights in a long-standing debate over how complex social behaviors arose in certain branches of bees' evolutionary tree.
Abstract 803: Impact of social isolation and quarantine on the course of diabetes mellitus and its complications during Covid 19 pandemic in Adjara Region Country of Georgia
Abstract 1337: Psychological distress in patients with hypocortisolism during mass quarantine for Covid-19 epidemic in Italy
Studies reveal that social isolation and quarantine throughout the COVID-19 pandemic may have a detrimental impact on people living with pre-existing conditions.
REYKJAVIK, Iceland 26 May 2021 - Current vaccination programmes alone will have a limited effect in stopping the second wave of COVID infections in the US, according to a study conducted by scientists from Reykjavik University, University of Lyon, University of Southern Denmark and University of Naples Federico II, and published in the Nature Group journal Scientific Reports today. The findings suggest that strict social distancing and other non-pharmaceutical methods are still necessary to end the ongoing second wave in the US and prevent a new one from rising.
Travelling elephants pay close attention to scent trails of dung and urine left by other elephants, new research shows.
Scientists monitored well-used pathways and found that wild African savannah elephants - especially those travelling alone - were "highly attentive", sniffing and tracking the trail with their trunks.
This suggests these scents act as a "public information resource", according to researchers from the University of Exeter and Elephants for Africa.
What information is retained in a memory over time, and which parts get lost? These questions have led to many scientific theories over the years, and now a team of researchers at the Universities of Glasgow and Birmingham have been able to provide some answers.
Their new study, which is published today in Nature Communications, demonstrates that our memories become less vibrant and detailed over time, with only the central gist eventually preserved. Moreover, this 'gistification' of our memories is boosted when we frequently recall our recent experiences.
COLUMBUS, Ohio - Time not only flies when you're having fun - sometimes anticipating a fun event makes it feel like it will be over as soon as it begins, a new study suggests.
Researchers found that people judge future positive events as being both farther away as well as shorter in duration than negative or neutral events.
Combining those two elements has a strange effect when people look forward to a positive event like a vacation, said Selin Malkoc, co-author of the study and associate professor of marketing at The Ohio State University's Fisher College of Business.
SAN RAMON, Calif., May 26, 2021--A new paper that has been accepted for publication in Ophthalmic & Physiological Optics, the peer-reviewed journal of The College of Optometrists (UK), furthers understanding of myopia control efficacy in the context of normal childhood eye growth. Axial Length Targets for Myopia Control (Chamberlain P, et al.) is now available online via Open Access.
UC San Francisco researchers have found a way to double doctors' accuracy in detecting the vast majority of complex fetal heart defects in utero - when interventions could either correct them or greatly improve a child's chance of survival - by combining routine ultrasound imaging with machine-learning computer tools.
University of Virginia School of Medicine scientists have developed important new resources that will aid the battle against cancer and advance cutting-edge genomics research.
Hundreds of antibiotic resistant genes found in the gastrointestinal tracts of Danish infants
Danish one-year-olds carry several hundred antibiotic resistant genes in their bacterial gut flora according to a new study from the University of Copenhagen. The presence of these genes is partly attributable to antibiotic use among mothers during pregnancy.
The Hubble parameter is one of the central parameters in the modern cosmology. Their values inferred from the late-time observations are systematically higher than those from the early-time measurements by about 10%. This is called the "Hubble tension". To come to a robust conclusion, independent probes with accuracy at percent levels are crucial. With the self-calibration by the theory of general relativity, gravitational waves from compact binary coalescence open a completely novel observational window for Hubble parameter determination.
A new rapid coronavirus test developed by KAUST scientists can deliver highly accurate results in less than 15 minutes.
The diagnostic, which brings together electrochemical biosensors with engineered protein constructs, allows clinicians to quickly detect bits of the virus with a precision previously only possible with slower genetic techniques. The entire set-up can work at the point of patient care on unprocessed blood or saliva samples; no laborious sample preparation or centralized diagnostic laboratory is required.
RICHLAND, Wash.--As the Clean Energy Transformation Act drives Washington state toward carbon-free electricity, a new energy landscape is taking shape. Alongside renewable energy sources, a new report finds small modular reactors are poised to play an integral role in the state's emerging clean energy future.
Modern genetic research often works with what are known as reference genomes. Such a genome comprises data from DNA sequences that scientists have assembled as a representative example of the genetic makeup of a species.
To create the reference genome, researchers generally use DNA sequences from a single or a few individuals, which can poorly represent the complete genomic diversity of individuals or sub-populations. The result is that a reference does not always correspond exactly to the set of genes of a specific individual.
Many eye diseases are associated with a restricted blood supply, known as ischaemia, which can lead to blindness. The role of the protein tenascin-C, an extracellular matrix component, in retinal ischaemia was investigated in mice by researchers from Ruhr-Universität Bochum (RUB). They showed that tenascin-C plays a crucial role in damaging the cells responsible for vision following ischaemia. The results were published online by the team in the journal Frontiers in Neuroscience on 20 May 2021.
