Contemporary artificial intelligence (AI) systems, such as the models underpinning the functioning of ChatGPT, image ...

People need to sleep, and sleep deprivation can cause many changes in the brain. But we have a poor understanding of why sleep is so crucial. New research has examined a fruit fly model to assess how ...

Researchers have identified an unexpected mechanism that links age-related stress to the decline of blood-forming stem cells. Instead of triggering cell death, a known signaling pathway subtly ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

Creating artificial systems that mimic the functioning of cells is one of the goals of what is known as synthetic biology. These models, known as synthetic or biomimetic cells, allow some of the basic ...

Scientists have pinpointed a mechanism that may explain heart cancer's rarity and point to new cancer treatments.

Women may have a stronger genetic predisposition to autoimmune diseases than men due to differences in how immune cells ...

By deploying a "tag and sort" fix using E3 ligases, scientists successfully cleared the protein buildup and restored T-cell ...

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes. The breakthrough ...

A Moffitt Cancer Center researcher has introduced a new model that addresses one of biology's most fundamental questions: How does genetic information keep living systems organized and therefore alive ...
