Molecular connections from plants to fungi to ants
Leaf-cutter ants tend gardens of fungi that efficiently deconstruct plant biomass. This process converts lipids in the leaves into lipids the ants can use. Lipids in these gardens are an energy source, a component of cells, ...

OSCAR detects cells in standby mode
Dormancy is a sleep-like state of cells that protects them from genetic damage and thus prolongs their survival. This state is reversible and characterized by low metabolic activity and division rate. Researchers from the ...

MicroRNAs may play a role in COVID-19
New research published in the Journal of Cellular and Molecular Medicine indicates that SARS-CoV-2, the virus that causes COVID-19, produces microRNAs that can have impacts on infected cells. MicroRNAs are genetic molecules ...

Flash mob in the nucleus: Study clarifies why some proteins 'flock together'
Almost all cells in our body contain a nucleus: a somewhat spherical structure that is separated from the rest of the cell by a membrane. Each nucleus contains all the genetic information of the human being. It serves as ...

Boost for mouse genetic analysis
To understand what role an individual gene plays, biologists have, for 100 years, been using a trick of nature: While in principle, the genome in all cells of an organism is the same, mutations arise in individual cells. ...

Deeply mining a universe of peptides encoded by long noncoding RNAs
Long noncoding RNAs (lncRNAs), a family of non-coding RNAs (ncRNAs) that are greater than 200 nucleotides in length, were formerly regarded as "junk RNAs" due to the lack of long or conserved open reading frames (ORFs).

How do developing spinal cords choose 'heads' or 'tails'?
The progression from a round ball of cells to an embryo with a head and a tail is one of the most critical steps in an organism's development. But just how cells first start organizing themselves with directionality along ...

Profiling gene expression in plant embryos, one nucleus at a time
Following fertilization, early plant embryos arise through a rapid initial diversification of their component cell types. As a result, this series of coordinated cell divisions rapidly sculpts the embryo's body plan. The ...
