Stigma silences those with hearing loss

A recent study reveals that nearly 60% of people with hearing loss feel embarrassed or uncomfortable sharing their struggles, while professionals often focus on stigma around hearing aids. The research highlights the need to challenge outdated stereotypes and encourages open conversations about hearing loss.

Researchers unlock safer RNA therapies for inflammatory diseases

Researchers have discovered two solutions to alleviate inflammation caused by lipid nanoparticles, making RNA therapies safer for patients with conditions like ARDS, heart attack, and stroke. A new biodegradable lipid and a common drug called thiodigalactoside (TG) can reduce inflammation while keeping RNA delivery effective.

The cerebral cortex ages less than thought

Researchers found that the primary somatosensory cortex, responsible for processing sensory information, has a layered structure that ages differently. The middle and upper layers remain stable or even thicken with age, while the lower layers show age-related degeneration, providing evidence for neuroplasticity.

Coastline of lakes an important part of global carbon cycle

New research reveals that lake littoral zones store more carbon than previously thought, highlighting the need for inclusion in global carbon budgets. By including these zones, lakes may switch from being net carbon sources to net carbon sinks.

Neurodegenerative diseases: What if the key lies in the mitochondria?

Researchers have established a causal link between mitochondrial dysfunction and cognitive symptoms associated with neurodegenerative diseases. By stimulating mitochondrial activity, they observed an improvement in memory deficit symptoms in animal models. The study opens the door to considering mitochondria as a new therapeutic target.

Pharmacotherapy for the management of obesity — an updated guideline

The updated Canadian Adult Obesity Clinical Practice Guideline recommends a personalized approach to treating obesity, focusing on waist circumference, waist-to-hip ratio, and waist-to-height ratio. Two new medications, tirzepatide and setmelanotide, are included in the guideline for managing obesity-related complications.

The study aims to refine models of galaxy evolution and cosmic structure, offering new insights into our understanding of the universe.

Blocking brain-liver communication may prevent deadly weight loss in cancer

Researchers discovered that disrupted brain-liver communication due to vagus nerve dysregulation leads to damage in liver metabolism and cachexia development. Targeted blocking of the right vagus nerve prevents cachexia's development, enhances chemotherapy response, and improves overall health and survival in mice.
