Maternal eating disorders, BMI, and offspring psychiatric diagnoses

JAMA Network Open

2024-10-22

(Press-News.org) About The Study: In this population-based cohort study including 392,000 mothers and 649,000 offspring, offspring from mothers with an eating disorder history or pre-pregnancy body mass index (BMI) outside normal weight were at higher risk of psychiatric disorders. The results differed somewhat between the 2 exposures with regard to which offspring diagnoses had associations, and effect sizes were typically larger for maternal eating disorders vs BMI. These findings suggest a need to consider these 2 exposures clinically to help prevent offspring mental illness.

Geometric mechanics shape the dog's nose

2024-10-22

The noses of many mammals, such as dogs, ferrets and cows, feature grooves forming a multitude of polygons. A team from the University of Geneva (UNIGE) has analyzed in detail how these patterns form in the embryo using 3D imaging techniques and computer simulations. The researchers discovered that differential growth of the skin tissue layers leads to the formation of domes, which are mechanically supported by the underlying blood vessels. This work describes for the first time this morphogenetic process, which could help explain the formation of other biological structures ...

‘Visual clutter’ alters information flow in the brain

2024-10-22

New Haven, Conn. — Whether we’re staring at our phones, the page of a book, or the person across the table, the objects of our focus never stand in isolation; there are always other objects or people in our field of vision. How that visual “clutter” affects visual processing in the brain, however, is not well understood. In a new study published Oct. 22 in the journal Neuron, Yale researchers show that this clutter alters how information flows in the brain, as does the precise location of that clutter within the wider field of vision. The findings ...

Researchers succeed in taking 3D x-ray images of a skyrmion

2024-10-22

A difficult-to-describe nanoscale object called the magnetic skyrmion might one day yield new microelectronic devices that can do much more — for example, massive data storage — all while consuming much less power. But researchers need a more detailed understanding of skyrmions if they are ever to be used reliably in computational devices, including quantum computers. Peter Fischer, a senior researcher at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley ...

MRI can save rectal cancer patients from surgery, study suggests

2024-10-22

Magnetic resonance imaging (MRI) can spare many patients with rectal cancer from invasive surgery that can carry lifelong side effects, new research indicates. The findings, from UVA Cancer Center’s Arun Krishnaraj, MD, MPH, and collaborators, indicate that MRI can predict patient outcomes and the risk of the tumor reccurring or spreading for patients who have undergone chemotherapy and radiation. That information could be extremely useful in determining the best course of treatment and deciding whether a patient can ...

Fyodor Urnov on clinical crisis in CRISPR genome editing

2024-10-22

New Rochelle, NY, October 18, 2024—An invited Guest Editorial entitled “Give Cas a Chance,” by Fyodor Urnov, PhD, Director of Technology & Translation at the Innovative Genomics Institute (IGI), anchors the October 2024 special issue of The CRISPR Journal on “CRISPR Trials.” As guest editor of the special issue, Dr. Urnov has penned an extraordinary editorial that emphatically defines the magnitude of the crisis in the genome editing arena and offers a path forward. The inherently programmable nature of CRISPR gene editing that makes it ...

People with type 2 diabetes who eat low-carb may be able to discontinue medication

2024-10-22

WASHINGTON—Adults with type 2 diabetes on a low-carbohydrate diet may see benefits to their beta-cell function allowing them to better manage their disease and possibly discontinue medication, according to new research published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. Beta-cells are endocrine cells in the pancreas that produce and release insulin, the hormone that controls blood sugar levels. More than 38 million Americans have diabetes, and over 90% of them have ...

Air pollution linked to having a peanut allergy during childhood

2024-10-22

Exposure to higher levels of air pollution as a baby is linked to having a peanut allergy throughout childhood, according to a new study. And policies aimed at tackling poor air quality could potentially reduce the prevalence and persistence of peanut allergies, it stated. The research, led by Murdoch Children’s Research Institute (MCRI) and the University of Melbourne, found being exposed to higher levels of air pollution from infancy was associated with increased odds of developing a peanut allergy and having the allergy persist across the first 10 years of life. However, the same association was not seen for egg allergy or eczema. Published ...

Dangers of the metaverse and VR for US youth revealed in new research

2024-10-22

The metaverse, a space where the lines between physical and digital realities blur, is rising among younger populations. As of March, 33% of teens own a virtual reality (VR) device and 13% use it weekly. With the metaverse offering richer emotional experiences, youth may be particularly vulnerable to significant harm in these immersive spaces, underscoring the need to explore potential risks. Unfortunately, research of online victimization in the metaverse is sorely lacking. A new study by Florida Atlantic University, in collaboration with the University of Wisconsin-Eau Claire, is one of the first to examine the ...

A national indicator for a just energy transition

2024-10-22

The Energy Transition Vulnerability Index (ETVI) quantifies the vulnerability of nations to adverse impacts of transitioning away from fossil fuels. The COP28 agreement has called for all countries to wind down use of fossil fuels to combat climate change—but the agreement stipulates that these transitions should not disproportionately harm historically marginalized and vulnerable stakeholders. Xunpeng Shi and colleagues create a method of quantifying energy transition vulnerability for 135 countries from 2010 to 2020. The indicator focuses on exposure—which captures the magnitude of the changes required—, ...

Cognitive effort whets the appetite for reward

2024-10-22

Mental fatigue may make rewards more desirable, according to a study in rats and humans. Exerting cognitive effort has been linked with making unhealthy choices. In the past, the link has been explained via a weaking of inhibitory control or will power. Marcello Solinas and colleagues explore the possibility that cognitive effort may also make unhealthy choices more tempting by increasing the perceived reward. Rats who completed a cognitively demanding task self-administered more cocaine than rats who did not complete a cognitive demanding task—or rats who were allowed ...
