Low-income mothers feminize their children in the womb by adjusting their hormones, whereas high-income mothers masculinize their children, a major study based on finger length, led by a Swansea University expert, has found.
The phenomenon is an unconscious evolutionary response aimed at boosting their offspring's chances of successful reproduction.
It helps, in part, explain associations between low income, low levels of testosterone before birth, and major causes of mortality such as cardiovascular disease.
In 2018, a faulty electric transmission line ignited the Camp Fire in Northern California, ultimately consuming 239 square miles and several communities, including the town of Paradise, which was 95 percent destroyed. At least 85 people died.
Washington, DC-- New research led by Carnegie's Yingwei Fei provides a framework for understanding the interiors of super-Earths--rocky exoplanets between 1.5 and 2 times the size of our home planet--which is a prerequisite to assess their potential for habitability. Planets of this size are among the most abundant in exoplanetary systems. The paper is published in Nature Communications.
As teens' use of social media has grown over the past decade, so too has the suicide rate among younger people, with suicide now being the second leading cause of death among those ages 10 to 34. Many have suggested that social media is driving the increased suicide risk, but because social media is still relatively new, it's been difficult to determine its long-term effects on mental health.
In the longest study to date on social media use and suicidality, BYU research recently published in the Journal of Youth and Adolescence now offers some answers.
What is the best way to monitor a brain tumor? This question is at the heart of a new Position Statement published in open-access journal Frontiers in Oncology. The article is the work of a large collaboration of UK experts and stakeholders who met to discuss the value of routinely imaging brain tumor patients to assess their tumor treatment response, which is known as "interval imaging".
The world is changing rapidly and in order to serve the human population dealing with those changes, American universities need to change, too. In fact, their role is to model the resiliency that all institutions need to embrace, according to Arizona State University President Michael M. Crow.
A new study from University of Alberta researchers has shown that traumatic or stressful events in childhood may lead to tiny changes in key brain structures that can now be identified decades later.
The study is the first to show that trauma or maltreatment during a child's early years--a well-known risk factor for developing mental health conditions such as major depressive disorder in adulthood--triggers changes in specific subregions of the amygdala and the hippocampus.
TORONTO (February 5, 2021) - A clinical study led by Dr. Jordan Feld, a liver specialist at Toronto Centre for Liver Disease, University Health Network (UHN), showed an experimental antiviral drug can significantly speed up recovery for COVID-19 outpatients - patients who do not need to be hospitalized.
This could become an important intervention to treat infected patients and help curb community spread, while COVID-19 vaccines are rolled out this year.
Washington, DC, February 5, 2021 - A study in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP), published by Elsevier, reports that in a diverse, cross-national sample of youth, physical discipline and cognitive deprivation had distinct associations with specific domains of developmental delay.
It's well understood that a difficult childhood can increase the likelihood of mental illness, but according to new research from the University of South Australia, a happy and secure childhood does not always protect a child from developing a mental illness later in life.
Conducted in partnership with the University of Canberra, the finding is part of a study published in Current Psychology, which examined how early childhood experiences relate to different developmental pathways, and how these might be associated with poor mental health.
We've all felt stressed at some point, whether in our personal or professional lives or in response to exceptional circumstances like the COVID-19 pandemic. But until now there has been no way to quantify stress levels in an objective manner.
That could soon change thanks to a small wearable sensor developed by engineers at EPFL's Nanoelectronic Devices Laboratory (Nanolab) and Xsensio. The device can be placed directly on a patient's skin and can continually measure the concentration of cortisol, the main stress biomarker, in the patient's sweat.
What The Study Did: Researchers estimated the rate of nurse burnout in the United States and the factors associated with leaving or considering leaving their jobs due to burnout.

This study is the first randomised control trial to rigorously test a sequential approach to treating comorbid PTSD and major depressive disorder.
Findings from a trial of 52 patients undergoing three types of treatment regime - using only Cognitive Processing Therapy (CPT), using Behavioural Activation Therapy (BA) with some CPT, or CPT with some BA - found that a combined treatment protocol resulted in meaningful reductions in PTSD and depression severity, with improvements maintained at six-month follow-up investigations.
The FinnBrain research of the University of Turku has demonstrated for the first time that the stress the father has experienced in his childhood is connected to the development of the white matter tracts in the child's brain. Whether this connection is transmitted through epigenetic inheritance needs further research.
A study published in the journal Pediatrics expands validation evidence for a new screening tool that directly engages preschool-age children during clinic visits to assess their early literacy skills. The tool, which is the first of its kind, has the potential to identify reading difficulties as early as possible, target interventions and empower families to help their child at home, according to researchers at Cincinnati Children's Hospital Medical Center.
