Metabolism is the means by which the body derives energy and synthesizes the other molecules it needs from the fats, carbohydrates and proteins we eat as food, by enzymatic reactions helped by minerals and vitamins.

Acidic Fortress of Tumors Could Rebuff Immune Cells

Cancer cells release a significantly more concentrated level of acid than previously known, forming an "acid wall" that could deter immune cells from attacking tumors, UT Southwestern Medical Center scientists show in a new study.

Autofluorescence Reveals Clues to Stem Cell Dormancy

With the help of a tool created at the University of Wisconsin–Madison, researchers can better study the various states of stem cells in the nervous system by utilizing the light naturally emitted by biological specimens.

New Theory Links Gene Length to Cellular Decline

A gene’s length may have more to do with aging than particular “aging genes.” Reduced expression of long genes may be the cause of many aging-related changes, according to researchers writing an opinion piece that was published in the journal Trends in Genetics on March 21st, 2023.

New Study Sheds Light on Blood-Brain Barrier Dysfunction in Aging

The central nervous system requires a tightly controlled environment for the neurons in the brain to function properly and be able to process information. The blood-brain barrier, which is maintained by specific brain endothelial cells lining blood vessel inner walls, controls the exchange of chemicals between the neurological and circulatory systems.

Unraveling the Role of Gene Length in Aging

Aging may be less about specific "aging genes" and more about how long a gene is. Many of the changes associated with aging could be occurring due to decreased expression of long genes, say researchers in an opinion piece publishing March 21 in the journal Trends in Genetics.

Metabolic Insights into Immune Cell Activation and Response

Researchers from Children's Hospital of Philadelphia identified a key metabolite in cells that helps direct immune responses and explains at a single cell level why immune cells that most efficiently recognize pathogens, vaccines, or diseased cells grow and divide faster than other cells.

Reducing Iron May Reverse Stem Cell Aging

It is fascinating to learn how researchers at the Albert Einstein College of Medicine and the National Cancer Institute-designated Montefiore Einstein Comprehensive Cancer Center (MECCC) have discovered a way to prevent or even reverse the function of hematopoietic (blood-forming) stem cells (HSCs) as they age.

Strategies to Counter Postnatal Growth Retardation in Piglets

The metabolic basis of postnatal growth retardation (PGR) in piglets is not yet clear, but it is characterized by poor production performance, low feed conversion rate, and a high mortality rate.

Microbial Viruses Found to be Key Players in Methane Cycling and Climate Change

In a new study, scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.

Fish Size and Climate Change: Study Refutes Gill Oxygen Limitation Theory

A collaborative team of scientists led by the University of Massachusetts Amherst recently found that there is no physiological evidence supporting a leading theory-; which involves the surface area of fish gills -;as to why many fish species are "shrinking" as waters grow warmer due to climate change.
