(Press-News.org) Previous research has identified genetic variants associated with insomnia and sleep duration in adults. Now a study published in the Journal of Child Psychology and Psychiatry has found that these variants also likely affect sleep quality and quantity in children.
In the study of 2,458 children of European ancestry, children who were genetically predisposed to insomnia (based on a polygenic risk score developed for adults) had more insomnia-like sleep problems such as frequent awakenings or difficulty initiating sleep, as reported by their mothers, whereas those who were genetically predisposed to longer sleep had longer sleep duration but were also more awake during the night in adolescence.
The authors noted that by showing that genes predisposing adults to insomnia also play a role in poor sleep from toddlerhood to adolescence, they provide indirect evidence for a ‘poor sleeper’ trait across the lifetime. “Our study shows that genetic susceptibility for poor sleep translates from adults to children. This finding emphasizes the importance of early recognition and prevention,” said corresponding author Desana Kocevska, PhD, of the Netherlands Institute for Neuroscience and the Erasmus MC University Medical Center Rotterdam.

Does cannabis use affect empathy?
2023-11-08
In a study published in the Journal of Neuroscience Research, psychological assessments indicated that people who regularly use cannabis, or marijuana, tend to have a greater understanding of the emotions of others. Brain imaging tests also revealed that cannabis users’ anterior cingulate—a region generally affected by cannabis use and related to empathy—had stronger connectivity with brain regions related to sensing the emotional states of others within one’s own body.
The study included ...
Framework provides guidance for ethical wildlife management
2023-11-08
Wildlife management decisions and practices face increasing ethical scrutiny. In research published in the Journal of Wildlife Management, investigators have developed a framework for incorporating ethical considerations into decisions in a systematic way.
The framework includes 3 domains: moral theory, which focuses on consequences and outcomes; principle- and rule-based approaches that deal with what is considered right or wrong; and virtue ethical therapy, which considers factors such as character, virtue, and aesthetics.
Wildlife ...
Could willow bark provide our next life-saving antiviral medicine?
2023-11-08
From a seasonal cold to a stomach bug, nobody likes catching a virus — and epidemics can be devastating. We need safe, sustainable antiviral options to treat the outbreaks of the future. Scientists in Finland have now shown that an extract of willow bark — a plant which has already provided several medicines, including the precursor to modern aspirin — has a broad-spectrum antiviral effect in cell sample experiments.
The extract worked both on enveloped coronaviruses, which cause colds as well as Covid-19, and non-enveloped enteroviruses, which cause infections such as flu and meningitis. There are no clinically approved drugs which work against enteroviruses directly, ...
Young children drinking daily caffeinated soda found more likely to try alcohol within a year
2023-11-08
The trend among younger children to frequently drink caffeinated soda may indicate higher risk of alcohol consumption in the future, new research suggests.
In a study of over 2,000 US children, aged between just nine to ten, those who reported drinking caffeinated soda daily, were found a year later twice as likely to state they had sipped alcohol.
Published in the peer-reviewed journal Substance Use & Misuse, the results of the study also demonstrate that daily drinkers of caffeinated soda were more impulsive and have a poorer working memory.
Each of the findings took into consideration other factors such as family history of drug use and low parental ...
Computer models fill critical knowledge gaps to help reduce cancer disparities
2023-11-08
WASHINGTON — Reducing health disparities in incidence and mortality for major types of cancers can be aided by sophisticated computer modeling efforts, according to new, wide-ranging perspectives from researchers at Georgetown University’s Lombardi Comprehensive Cancer Center and colleagues around the country. The collection of articles appears in the November 8, 2023, special issue of JNCI and are devoted to outlining a path forward in cancer disparities modeling.
The issue was edited by Georgetown Lombardi’s Jeanne ...
Southern Alaska’s national forests key to meeting climate, conservation goals, OSU study shows
2023-11-08
CORVALLIS, Ore. – Analyses of U.S. national forests led by Oregon State University scientists shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
In a paper published in AGU Advances, OSU College of Forestry researchers make the case that greater conservation efforts in the Tongass and Chugach national forests in southern Alaska are crucial because of their landscape integrity, high carbon stocks and wildlife habitat extent.
“More thoroughly safeguarding those forests ...
Experts predict ‘catastrophic ecosystem collapse’ of UK forests within the next 50 years if action not taken

A copy of the paper is available at: https://drive.google.com/drive/folders/1oj1uPIh_R0D_SA9wHtaaoz_NG26SicI4?usp=drive_link
A team of experts from across Europe has produced a list of 15 over-looked and emerging issues that are likely to have a significant impact on UK forests over the next 50 years.
This is the first ‘horizon scanning’ exercise – a technique to identify relatively unknown threats, opportunities, and new trends – ...
Virtual/augmented reality playkit eases kids’ and parents’ anxieties ahead of MRI scan
2023-11-08
Giving children a virtual/augmented (mixed) reality playkit to use ahead of an MRI (magnetic resonance imaging) scan seems to ease both their and their parents’ anxieties about this procedure, suggest preliminary findings published in the open access journal BMJ Innovations.
Reducing the need to put a child to sleep, because of the noise and time required to keep still while in the MRI tunnel, could not only boost patient safety, but also cut costs and waiting times, suggest the researchers.
MRI has emerged as an important diagnostic tool in children’s healthcare because of the high quality images produced and lower radiation ...
Three-fold rise in babies born at 22 weeks given respiratory life support in England and Wales after guidelines change
2023-11-08
The number of very premature babies (22 weeks) given respiratory life support (survival focused care) and/or admitted to neonatal units in England and Wales has increased 3-fold, following changes in 2019 to national guidance, finds research published in the open access journal BMJ Medicine.
While the proportion of these babies surviving to discharge has also increased, overall survival remains low, and there are “major implications for additional resource needs,” highlight the researchers.
The updated national guidance from the British Association of Perinatal Medicine focuses on a risk based approach, setting out various pregnancy and ...
Why a surprising discovery, warming seas and the demise of the ‘Meg’ may spell trouble for more and more sharks
2023-11-08
Some unexpected shark strandings and subsequent surprises following autopsies have, ironically, taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the “Meg”), they think their work suggests there are more warm-blooded sharks out there than previously believed, and – based on the Meg’s demise – these species may be at great risk from warming seas.
Some of the most ...
