New blood test identifies obesity-related health risks in children

A new type of blood test using lipids could make it easier to identify children at risk of complications around obesity including type two diabetes, liver and heart disease, say scientists.

Amyloid-β and tau disrupt brain activity, driving early cognitive decline in Alzheimer’s risk

Researchers discover how amyloid-β and tau pathologies interact to drive early neurophysiological changes and cognitive decline in older adults at risk of Alzheimer’s disease.

New research strengthens the case for a zoonotic origin of COVID-19

A new international collaborative study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and Prevention (CDC).

A novel in vitro model for studying wrinkle formation in biological tissues

A research team consisting of Professor Dong Sung Kim, Professor Anna Lee, and Dr. Jaeseung Youn from the Department of Mechanical Engineering at POSTECH has successfully recreated the structure of wrinkles in biological tissue in vitro, uncovering the mechanisms behind their formation. Their findings were published on August 19 in the international journal Nature Communications.

An evolutionary ancient brain region drives modern-day cognition

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright flash of light. New research from the University of Chicago shows that this part of the brain also plays a role in complex cognitive tasks like visual categorization and decision making.

Hypothalamic ECM remodeling drives insulin resistance, contributing to obesity and diabetes

Researchers have discovered that remodeling of extracellular matrix (ECM) in the hypothalamus, specifically around AgRP neurons, drives insulin resistance and metabolic disease. Disrupting this ECM buildup improves insulin sensitivity and may be a promising treatment for obesity and diabetes.

Do long genes hold the key to understanding the genetic underpinnings of aging?

Review highlights the growing evidence that aging is linked to reduced expression of long genes, offering insights into potential anti-aging therapies based on gene length.

Study reveals MYC gene's role in prostate cancer initiation and progression

By tracking the changes in prostate cancer cells over time, researchers at the Johns Hopkins Kimmel Cancer Center have found that activation of the MYC gene -; a well-known cancer-causing gene -; sets off a cascade of events that leads to both initiation and progression of the disease.

Researchers identify bacterial strains to combat antibiotic-resistant gut infections

Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time.

Immune proteins in tooth enamel provide clues about ancient human health

A new way of looking at tooth enamel could give scientists a path to deeper understanding of the health of human populations, from the ancient to the modern.

Global fight against antimicrobial resistance sees surge in deaths among older adults

Comprehensive study estimates the global antimicrobial resistance (AMR) burden from 1990 to 2021, identifying significant age and regional disparities. It highlights future AMR death projections and underscores the importance of prevention and new antibiotic development.

Cellular sludge around hunger neurons linked to worsening diabetes and obesity

Investigating ECM changes in the hypothalamus reveals mechanisms behind insulin resistance, offering insights into obesity and metabolic disease treatment.

Study reveals impact of human breast milk on infant microbiome and respiratory health

Human breast milk regulates a baby's mix of microbes, or microbiome, during the infant's first year of life. This in turn lowers the child's risk of developing asthma, a new study shows.

New model reveals mechanisms of lung injury from mechanical ventilation

For the first time, scientists are able to directly compare the different kinds of injury that mechanical ventilation causes to cells in the lungs.

Analyzing the connection between lifelong activity and longevity in aging research

A new research perspective was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), Volume 16, Issue 17 on September 9, 2024, entitled, "Longitudinal activity monitoring and lifespan: quantifying the interface."

Study reveals links between bodily rhythms and visual perception

A study funded by the SNSF highlights previously unknown links between the body and the brain. The findings of this research carried out at the University of Fribourg show how our bodily rhythms affect our visual perception.

Hypoxia's hidden role in boosting anti-cancer immunity

In the complex landscape of cancer, tumors create their own microenvironment, often marked by low oxygen levels, a condition known as hypoxia.

Cardiovascular disease pathways associated with psoriasis, but not other immune-mediated diseases

A genetic connection between cardiovascular disease and psoriasis highlights shared inflammatory pathways, emphasizing the need for cardiovascular monitoring.

19 Sep 2024

Study highlights disparities in stroke burden across regions

Although stroke is highly preventable and treatable, there has been a rapid rise in the global stroke burden between 1990 and 2021, due to both population growth and the rise of aging populations worldwide, as well as a substantial increase in people's exposure to environmental and behavioral risk factors.
