A new on-site study of portraits decorating the walls of ancient Egyptian tombs has revealed instances where designs were painted over and altered, possibly during subsequent Egyptian dynasties.

Circular DNA, thought to be an accidental byproduct, is borrowing the cell’s DNA repair mechanisms to copy itself.

Immune system recognition of allergens and pathogens in the environment allows the brain to take defensive measures, such as avoidance.

A new study explains how basic cellular structures common to most life forms collaborate to fuel growth in a model plant organism. The findings could shed light on corresponding mechanisms in human cells.

New research shows the need for an international effort to limit global pollution by PFAS. The substance inhibits the immune system and can, thus, increase the risk of infections and cancer.

Scientists contest longstanding hypothesis about mysterious illness affecting Gulf War veterans, providing first direct evidence that symptoms are driven by impaired mitochondria.

Human breast milk is a nutrient-rich mix that helps nurture newborns through an essential period of development. New evidence suggests that one particular compound derived from breast milk, the sugar myo-inositol, might play an important role in the maturation of the newborn brain.

As our world grows louder by the day, more and more people are searching for a little silence. Now, a new study suggests that our brains can hear silence in the same way it perceives sound.

A team of researchers has discovered that the memory of the immune system relies on characteristic epigenetic features and a specific 3D arrangement of the DNA in the nucleus of memory cells, allowing for a fast activation of these cells.

A team led by researchers at Penn State has identified a protein that modifies the cellular machinery responsible for producing cellulose.
