Plants fix 258 billion tons of CO 2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

In response to stress or damage, cells undergo senescence and stop dividing. However, if senescent cells accumulate in tissues over the long term, chronic inflammation occurs and the risk of cancer ...

Researchers have uncovered rapid chemical reactions in living cells that may protect the body from damage - a discovery with implications for diabetes and aging When we consume foods containing sugar ...

Lysosomes are the control centers for the metabolism of cells and tissues, including the brain. They break down defective proteins and other macromolecules into their basic building blocks. At the ...

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.

Researchers from National Taiwan University (NTU) and National Taiwan University Hospital (NTUH) have identified a promising way to reinvigorate the body's cancer-fighting immune cells by rewiring ...

When people think about health, they often focus on specific organs like the heart or brain. But many changes related to chronic conditions or ageing begin in the smallest units of your body — your ...

How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open ...
