Scientists Reveal How our Cells’ Leaky Batteries are making us Sick

Rheumatoid arthritis is a chronic inflammatory condition that can damage joints.

The new findings could lead to better treatments for rheumatoid arthritis, lupus and other inflammatory diseases – and may even help us slow aging.

Researchers have discovered how “leaky” mitochondria can drive harmful inflammation responsible for diseases such as lupus and rheumatoid arthritis. Scientists may be able to leverage the findings to develop better treatments for those diseases, improve our ability to fight off viruses and even slow aging.

The new discovery reveals how genetic material can escape from our cellular batteries, known as mitochondria, and prompt the body to launch a damaging immune response...

Scientists Identify how Dietary Restriction Slows Brain Aging and Increases Lifespan

Restricting calories is known to improve health and increase lifespan, but much of how it does so remains a mystery, especially in regard to how it protects the brain. Buck Institute for Research on Aging scientists have uncovered a role for a gene called OXR1 that is necessary for the lifespan extension seen with dietary restriction and is essential for healthy brain aging.

“When people restrict the amount of food that they eat, they typically think it might affect their digestive tract or fat buildup, but not necessarily about how it affects the brain,” said Kenneth Wilson, Ph.D...

Inflammation Discovery could Slow Aging, Prevent Age-related Diseases

University of Virginia School of Medicine researchers have discovered a key driver of chronic inflammation that accelerates aging, a finding that could lead to longer, healthier lives and the possible prevention of age-related conditions such as deadly heart disease and devastating brain disorders.

The harmful inflammation is driven by improper calcium signaling in the mitochondria of certain immune cells, researchers found. Mitochondria are the power generators in all cells, and they rely heavily on calcium signaling.

The Feeling of Hunger itself may Slow Aging in Flies

From low-carb to intermittent fasting, surgery to Ozempic — people turn to a seemingly never-ending array of diets, procedures and drugs to lose weight. While it has been long understood that limiting the amount of food eaten can promote healthy aging in a wide range of animals, including humans, a new study from University of Michigan has revealed that the feeling of hunger itself may be enough to slow aging.

Previous research has demonstrated that even the taste and smell of food can reverse the beneficial, life-extending effects of diet restriction, even without its consumption.

These intriguing findings drove first author Kristy Weaver, Ph.D., principal investigator Scott Pletcher, Ph.D...
