New study uncovers how prior obesity impacts viral consequences

A study comparing the effects of SARS-CoV-2 infection in lean and obese primates found different long-term consequences of the virus depending on prior obesity and metabolic disease. The results, which also highlighted how widespread long COVID symptoms are in animals, were published July 24th in the open-access journal PLOS Pathogens by Charles Roberts of Oregon Health & Science University, USA, and colleagues.

In-depth look at breast tumor growth and surgical delay effects

Using a novel method to analyze tumor growth rates, researchers at Fox Chase Cancer Center have provided the most in-depth assessment to date of how fast breast cancers grow in patients and how surgical delays may affect breast cancer staging, which measures the extent of cancer spread in the body. The newly published study offers new insight into how tumors progress in the time between diagnosis and surgery.

New research shows neurogenesis slows in early adulthood, impacting memory

Age often brings a gradual decline in the ability to learn new things and retain memories. This phenomenon, often associated with the elderly, is linked to the brain's deteriorating capacity to generate new neurons-a process that primarily occurs in the hippocampus -as neural stem cells (NSCs) divide and mature. Recent research suggests this decline begins much earlier in life than previously thought, potentially starting in early adulthood.

Blocking nutrient scavenging weakens pancreatic tumor defenses

Cancer cells and tumors do not exist in a vacuum. Far from the isolation and self-sufficiency of the fictional Wakanda, tumors develop in and alter the nearby milieu of immune cells, connective tissue, blood vessels and a sea of proteins and carbohydrates that provide structure and other supportive functions.

Mathematics offers new clues in the fight against Alzheimer's

Mathematics may not be the first thing people associate with Alzheimer's disease research. But for Pedro Maia, an assistant professor of mathematics and data science at The University of Texas at Arlington, analyzing how different parts of the brain interact like a network is revealing new insights into one of the world's most devastating brain disorders.
