People in industrialized regions like the United States of America or Europe are generally urged to eat less meat and animal-source foods as part of a healthier and lower-emissions diet. But such recommendations are not universal solutions in low- or middle-income countries, where livestock are critical to incomes and diets, argue scientists in recently published research in Environmental Research Letters.
The spread of the Internet is shaping migration in profound ways. A McGill-led study of over 150 countries links Internet penetration with migration intentions and behaviours, suggesting that digital connectivity plays a key role in migration decisions and actively supports the migration process.
LA JOLLA, CA--Scientists at Scripps Research have demonstrated a promising new strategy for treating lymphomas, a group of cancers that begin in infection-fighting cells of the immune system called lymphocytes.
LA JOLLA, CA--Made in clandestine laboratories and sold widely across the United States, the diverse class of drugs known as synthetic cannabinoids presents a growing public health threat.
In a new study, Scripps Research scientists have devised a way to deactivate these designer drugs after they've been administered--offering a potential path for treating addiction and overdose.
A common analogy used to describe the brain is that it consists of tiny interconnected computers. Each one of these computers, or neurons, process and relay activity from thousands of other neurons, forming complex networks that allow us to perceive our surroundings, make decisions, and guide our actions. Communication between neurons occurs through tiny connections called synapses, and each neuron integrates the activity across these synapses to form a single output signal. However, not all synapses are created equal.
OTTAWA, ON _The COVID-19 pandemic is seriously affecting the sleep habits of half of those surveyed in a new study from The Royal and the University of Ottawa, leading to further stress and anxiety plus further dependence on sleep medication.
At some point, everyone experiences nausea. Whether it occurs after unwisely eating a week-old slice of pizza or as an accompaniment to a serious infection, that queasy, unsettling sensation centered around the stomach is a signal that something is amiss within the body and typically portends a bout of vomiting.
Most of the time, nausea is only temporary. But for some people, such as those on certain chemotherapy regimens, it can be severe, chronic and even life-threatening when it prevents patients from adhering to treatment.
Women face a 20 per cent higher risk than men of dying or having heart failure during the five years following a heart attack, according to a new study from University of Alberta cardiology researchers.
Getting good quality sleep, exercising, and eating more raw fruits and vegetables predicts better mental health and well-being in young adults, a University of Otago study has found.
The study, published in Frontiers in Psychology, surveyed more than 1100 young adults from New Zealand and the United States about their sleep, physical activity, diet, and mental health.
The stickleback is a well-studied system in freshwater lakes, but the evolution of convergent morphotypes that occupy different positions in the water column in marine environments is less clear. An international group of scientists led by researchers at the University of Oklahoma decided to test the extent to which independent transitions from bottom to midwater habitats in marine fish species from different oceanic basins resulted in the recurrent evolution of body shape morphologies, comparable to those documented in sticklebacks.
Hatchery-reared Atlantic salmon (Salmo salar) have been released to support the wild salmon stocks in the Baltic Sea for decades. During their feeding migration, salmon are exposed to organohalogen compounds (OHCs). Here, we investigated the OHC levels and transcriptome profiles in the liver of wild and hatchery-reared salmon collected from the Baltic main basin, the Bothnian Sea, and the Gulf of Finland and examined whether salmon origin and OHC levels contributed to the hepatic transcriptome profiles.
WASHINGTON--The Endocrine Society and the Pediatric Endocrine Society oppose legislative efforts to block transgender and gender diverse individuals from accessing gender-affirming medical and surgical care, the two medical societies said in a joint policy perspective published in The Journal of Clinical Endocrinology & Metabolism.
Bottom Line: Esophageal adenocarcinoma is occurring more frequently in adults under age 50, and these younger adults are more likely to be diagnosed at advanced stages.
Journal in Which the Study was Published: Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research
Author: Prasad G. Iyer, MD, MSc, professor of medicine in the Barrett's Esophagus Unit, Division of Gastroenterology and Hepatology; and Don C. Codipilly, MD, a gastroenterology fellow, both at the Mayo Clinic in Rochester, Minnesota.
Washington, December 16, 2020--When the emerging COVID-19 pandemic caused most U.S. schools to close and transition to distance learning last spring, many parents were forced into new roles as proxy educators for their children. A study published today in Educational Researcher, a peer-reviewed journal of the American Educational Research Association, finds that roughly 51 percent of all parents surveyed in March and April had at least one child struggling with distance learning and were themselves experiencing significantly higher levels of stress.
Researchers at Tohoku University have revealed further insight into the fetal development of our brain and the potential causes of Fragile X syndrome (FSX).
During brain development, the fetal period is vital in creating neurons from neural stem cells to build up a functional adult brain. Any impairment in the developmental program could result in severe defects in the brain.
FSX is a genetic disorder characterized by intellectual disability and autistic symptoms. Children with FSX will generally suffer from developmental delays as well as social and behavioral problems.
