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 ...

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. ...

Cohesin opens up for cell division

Scientists at Nagoya University, with colleagues at Kyoto University in Japan, have uncovered a mechanism that allows a protein complex to bind to DNA without impeding some of the important processes of cell division. Their ...

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 ...

There's more to genes than DNA: How Mum and Dad add something extra

Biologists at the Universities of Bath and Vienna have discovered 71 new 'imprinted' genes in the mouse genome, a finding that takes them a step closer to unraveling some of the mysteries of epigenetics—an area of science ...

Females supercharge sperm evolution in animals

Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job—to fertilize eggs? In a new article published in Nature Ecology and Evolution, researchers from ...

Combating antibiotic-resistant Staphylococcus aureus

A research team led by Professor Hongzhe Sun, Norman & Cecilia Yip Professor in Bioinorganic Chemistry and Chair Professor from Research Divison for Chemistry and Department of Chemistry, Faculty of Science, in collaboration ...

Stronger together: How protein filaments interact

Just as the skeleton and muscles move the human body and hold its shape, all the cells of the body are stabilized and moved by a cellular skeleton. Unlike the vertebrate skeleton, this cellular skeleton is a very dynamic ...
