This amoeba, a single-celled organism, acquires energy by engulfing nutrients in the form of a yeast cell (red). Through a process called phagocytosis, the amoeba encloses the yeast cell with its ...

Antibiotics are medical marvels that have transformed once deadly bacterial infections into manageable conditions. But with a ...

While cancer cells have been known to compete with each other for resources, it seems that they have also found a way to work together to gather nutrients. When exposed to amino acids, cells can ...

Scientists at New York University have found that cancer cells work together to source nutrients from their environment—a cooperative process that was previously overlooked by researchers. The team’s ...

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon aging. Researchers have discovered a new mechanism of action between the nutrient adaptation of intestinal ...

The decision between scrambled eggs or an apple for breakfast probably won't make or break your day. However, for your cells, a decision between similar microscopic nutrients could determine their ...

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

The immune system relies on specialized “effector” T cells to fight off pathogens. However, in chronic infections such as cancer or HIV, the perpetual activation of these cells can turn them into ...

Statin drugs are commonly taken to help manage cholesterol levels, and they have a good track record of preventing heart attacks and strokes in at-risk patients. But now, researchers at Johns Hopkins ...

Scientists at the University of Bristol have developed a new kind of bio-ink, which could eventually allow the production of complex tissues for surgical implants. The new stem cell-containing bio ink ...

Nutrient adaptation refers to the way in which nutrients guide cell function. Researchers at the University of Helsinki identified a new regulatory mechanism that directs the differentiation of ...
