If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be ...

AI tool reveals single-cell structure of chromosomes—in 3D by Eric Stann, University of Missouri edited by Gaby Clark, reviewed by Robert Egan Editors' notes ...

The Randles circuit (including a parallel resistor and capacitor in series with another resistor) and its generalized topology have widely been employed in electrochemical energy storage systems, such ...

Scientists achieved “a milestone” by charting the activity and structure of 200,000 cells in a mouse brain and their 523 million connections. A neuron extends an axon to make contact with ...

It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.

Structure of eukaryotic cells Eukaryotic cells generally contain several membrane-bound organelles, including the nucleus, mitochondria, the ER, the Golgi apparatus and lysosomes (Figure 1). Plant ...

Cancer cells rely on this machinery for shuttling energy to help meet their ravenous fuel demands. Studies of breast cancer cells have highlighted the importance of a type of CK called ubiquitous ...

The discoveries could also help scientists working on stem cell therapies, since coaxing a stem cell to become a neuron or heart cell requires shifting it from one genetic program to another — each ...

A generalized methodology to design low-profile transmitarray (TA) antennas made of several stacked layers with nonresonant printed phasing elements is presented. A study of the unit cell bandwidth, ...

A key takeaway from first-year biology is that mitochondria are the powerhouses of cells—it’s the thing most people know about them. However, mitochondria perform a large array of functions for cells ...

Altering the genomic structure of cells can explain changes in gene expression. Those changes, in turn, could explain the symptoms that someone experiences when they’re infected with COVID-19 ...

The interior design of our cells: Database of 200,000 cell images yields new mathematical framework to understand our cellular building blocks Scientists have just debuted a new way to see how ...
