Fever enhances immune cell activity and induces mitochondrial stress

Fever temperatures rev up immune cell metabolism, proliferation and activity, but they also - in a particular subset of T cells - cause mitochondrial stress, DNA damage and cell death, Vanderbilt University Medical Center researchers have discovered.

New two-dose HIV vaccine strategy shows promise for stronger immune response

One major reason why it has been difficult to develop an effective HIV vaccine is that the virus mutates very rapidly, allowing it to evade the antibody response generated by vaccines.

Lipid biomarkers in children with obesity linked to future cardiometabolic risks

Scientists from the University of Copenhagen have detected lipid biomarkers in children and teenagers with obesity that indicate an increased risk of developing type 2 diabetes, liver and heart disease as adults.

New model explains how the brain restores walking rhythm after disruptions

Walking is an activity that is often taken for granted. Most people usually think they can multitask by "walking and chewing gum" simultaneously with hardly any taxation of their mental effort.

STING protein plays new role in cellular stress clearance and survival

A protein called STING, previously shown to control a pathway that contributes to antiviral signaling, also plays an important role in cellular stress clearance and cell survival, according to a new paper published in Molecular Cell.

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.
