  A study by IRB Barcelona unveils how the lack of a fraction of the CPEB4 protein causes a decrease in the expression of genes that are crucial for neuronal development. Published in the journal Nature, the study opens new avenues for the development of targeted treatments for autism. Barcelona, 4 December 2024 –Autism is a neurodevelopmental disorder characterised by difficulties in communication and social behaviour. Approximately 20% of cases are linked to a specific genetic mutation, but the origin of the remaining 80%, known as idiopathic autism, remains a mystery. A team of scientists led by Drs. Raúl Méndez and Xavier Salvatella at the Institute ...

Researchers at UCSF find a brain signature of resilience in mice that suggests a new way of treating severe depression.  Some people bounce back from trauma, but others get caught in depressive loops that sap the joy from their lives.   Now, scientists at UC San Francisco are learning how the brain creates these divergent experiences. They hope it will help them find a way to treat those who struggle with long-lasting symptoms of stress.  The researchers found that stress changes activity in a brain circuit ...

Fructose consumption has increased considerably over the past five decades, largely due to the widespread use of high-fructose corn syrup as a sweetener in beverages and ultra-processed foods. New research from Washington University in St. Louis shows that dietary fructose promotes tumor growth in animal models of melanoma, breast cancer and cervical cancer. However, fructose does not directly fuel tumors, according to the study published Dec. 4 in the journal Nature. Instead, WashU scientists discovered that the liver converts fructose into usable nutrients for cancer cells, a compelling finding that could open up new avenues for care and treatment ...

A study published today in Cell uncovers the deep evolutionary roots of flint and dent maize (also commonly known as “corn”), two foundational varieties central to modern maize breeding and cultivation.

DALLAS, December 4, 2024 — An estimated 1 in 500 people in the U.S. are living with hypertrophic cardiomyopathy (HCM) — the most common inherited heart disease — and many are unaware.[1] HCM is a thickening of the lower main pumping chamber of the heart (the left ventricle). The disease is often underdiagnosed and inconsistently managed, leading to delayed treatment, increased risk of complications and preventable death. Yet, systems of care for this disease are fragmented and varied. To overcome these gaps in care, the American Heart Association, celebrating a century of lifesaving service in 2024, has launched a new three-year initiative to ...

Scattered across the United States are remnants from almost 170 years of commercial drilling: hundreds of thousands of forgotten oil and gas wells. These undocumented orphaned wells (UOWs) are not listed in formal records, and they have no known (or financially solvent) operators. They are often out of sight and out of mind – a hazardous combination.  If the wells weren’t properly plugged, they can potentially leak oil and chemicals into nearby water sources or send toxic substances like benzene and hydrogen sulfide into the air. They can also contribute ...

PULLMAN, Wash. — Teens who think their parents use cannabis are more likely to hold favorable attitudes toward the drug and to consider trying it themselves, according to a new Washington State University study. The research, published in the Journal of Child and Family Studies, also reveals that parental monitoring and the closeness of parent-child relationships play crucial roles in adolescents’ views about cannabis, often with distinct effects based on the parent’s gender.
