WASHINGTON--With the help of Inuit hunters, geophysicists recently recorded the various calls, buzzes, clicks and whistles of narwhals as they summered in a Greenland fjord. The recordings help scientists better understand the soundscape of Arctic glacial fjords and provide valuable insight into the behavior of these shy and mysterious creatures, according to the researchers.
Findings from a new NUI Galway study on workplace bullying, led by Dr John Cullinan of the Discipline of Economics and Dr Margaret Hodgins from the Discipline of Health Promotion, has been published in the journal Occupational Medicine.
VANCOUVER, Wash. - Some of the most common mental disorders, including depression, anxiety and PTSD, might not be disorders at all, according to a recent paper by Washington State University biological anthropologists.
Various diseases in humans and animals - such as tumors, strokes or chronic kidney disease - damage the blood vessels. Capillaries, the smallest blood vessels in the body, are particularly affected. The large surface area of the capillary network enables oxygen to be exchanged between the blood and the surrounding tissue, such as the muscles when we exercise or the brain when we think.
Revealing the vascular structure
Australian archaeologists have discovered some of the most detailed examples of rare, small-scale rock art in the form of miniature stencils in a rockshelter traditionally owned by the Marra people.
The research, published in the journal Antiquity, examined the unusual art found in the Yilbilinji rockshelter at Limmen National Park in the southwest Gulf of Carpentaria region of northern Australia.
Traditionally owned by the Marra Aboriginal people, the site was documented by the research team in 2017 and instantly stood out as unique.
To simulate in a laboratory what happens in particle accelerators has been an ambitious goal in the study of the fundamental forces of nature pursued by high-energy physicists for many years. Now, thanks to research conducted by the groups of statistical physics of SISSA - Scuola Internazionale Superiore di Studi Avanzati and the "Abdus Salam" International Centre for Theoretical Physics (ICTP), that goal is closer to reach.
Spring has sprung earlier than ever before this year, accompanied by temperatures more typical of early summertime. Many plants were already in full bloom by mid-?April, about three to four weeks earlier than normal. These types of seasonal anomalies are becoming increasingly frequent due to climate change, and the resulting uncertainty threatens to disrupt the timing of mutualistic relationships between plants and their insect pollinators.
Osaka, Japan - Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific receptors on the cell surface, stimulating signaling pathways and altering gene expression.
Antibodies for potential use as medicines can be made rapidly in chicken cells grown in laboratories. Researchers refer to their technique as the human ADLib system, short for autonomously diversifying libraries. The technique automatically builds vast numbers, or libraries, of diverse antibodies using chicken immune system cells' natural method for shuffling their genes.
There is an extremely high probability that individuals with 22q11.2 micro deletion syndrome - a rare genetic disorder - will develop schizophrenia together with one of its most common symptoms, auditory hallucinations. Scientists at the University of Geneva (UNIGE) and the Synapsy National Centre of Competence in Research (NCCR) have been studying this category of patients. They have succeeded in linking the onset of this hallucinatory phenomenon with the abnormal development of certain substructures of a region deep in the brain called the thalamus.
GP's notes currently unavailable to medical researchers could provide clues to help manage major health crises - like COVID-19.
And according to a 'citizens' jury' study at Brighton and Sussex Medical School (BSMS), the main thing stopping the use of such information - concerns over patient privacy - could be overcome.
Few species develop as slowly as humans, both in terms of developing adult skills and in terms of brain development. Human infants are born so underdeveloped that they cannot survive without adult care and feeding for some years after birth. Children still need to learn fundamental skills such as walking, eating, talking, using tools and much more. The timing of when these developmental milestones emerge is used by doctors to determine if your child and your child's brain are developing normally.
At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene profiling or protein analysis destroy the cell, study is confined to just that one moment in time, and researchers are unable to return to the cell to examine how things change beyond that snapshot.
DALLAS, May 26, 2020 -- Higher spirituality among stroke survivors was strongly linked to better quality of life for them and their caregivers who may also feel depressed, according to new research published today in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. May is American Stroke Month.
For many stroke survivors, a caregiver, often a family member or close friend, may help with daily tasks, making the survivor and the caregiver prone to depression. Depression can impact quality of life for both.
Having a faulty gene linked to dementia doubles the risk of developing severe COVID-19, according to a large-scale study.
