Researchers have developed synthetic genes that function like the genes in living cells. The artificial genes can build intracellular structures through a cascading sequence that builds ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these ...

In A Nutshell As cells age, they deliberately shrink a major internal structure called the endoplasmic reticulum. This downsizing happens early in adulthood and shifts cells away from protein ...

In a recent study published in the journal Nature, a large team of researchers from the United States (U.S.) used single-cell ribonucleic acid (RNA) sequencing combined with high-resolution ...

These include stress granules and proteasome storage granules (PSGs). In the past, these membraneless organelles were only visible as “droplets” using a fluorescence microscope. Now, researchers from ...

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Digital camera images of the entire body (top left) and dorsal mantle (top right) of a squid show the splotches’ blue, green, yellow, orange and red iridescent (angle-dependent) colors. An individual ...

The cochlea is the spiral-shaped structure within the inner ear responsible for our sense of hearing. To fully understand hearing functions and open the door to new hearing loss treatments, scientists ...
