In living organisms, the cell membrane plays a crucial role. It’s not just a protective barrier—it also senses the environment, helps transport molecules, and allows cells to adapt and change. This ...

Scientists have discovered how the amino acid leucine boosts the body’s energy production by protecting key mitochondrial proteins from breaking down. This process allows mitochondria, the cell’s ...

Cell growth is the most fundamental process in organisms, yet the way in which metabolism determines its rate has long remained unclear. To decipher this mystery, researchers from Earth-Life Science ...

At some point during the evolution of life on Earth, inorganic matter became organic, nonliving matter became living. How this happened is one of humankind's greatest mysteries. Today, scientists work ...

An international research team focused on aging reports that urolithin A at 1,000 mg per day shifted human immune profiles ...

Urolithin A, a natural postbiotic known to trigger mitophagy, rejuvenated key immune cell functions in healthy middle-aged ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...

Researchers have developed a noninvasive Raman spectroscopy approach to map how egg cell metabolism changes with age. The study shows that older mouse oocytes display delayed metabolic maturation ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules.

Free radicals generated at a specific site in non-neuronal brain cells called astrocytes may promote dementia, according to a ...
