Pinpointing the molecular mechanisms of ageing

Although each and every one of us goes through it, ageing is a poorly understood process. Researchers have used a biomarker called the epigenetic clock to identify a gene that is closely linked to ageing in humans. The study, ...

Cell polarity: An aurora over the pole

Even before the fertilised egg or zygote can start dividing into daughter cells that form the future tissues and organs during the development of a multicellular organism, the symmetrical zygote needs to become asymmetrical ...

New machine learning model describes dynamics of cell development

From their birth through to their death, cells lead an eventful existence. Thanks to single-cell genomics, their destiny in large cell populations can now be analyzed. However, this method destroys the cell, which makes it ...

Researchers uncover intracellular longevity pathway

The search for clues on how to live healthier, longer lives has led researchers at Baylor College of Medicine to look inside the cells of the worm Caenorhabditis elegans. The researchers report in the journal Developmental ...

Sexual development in fungi

Biologists at Ruhr-Universität Bochum and Georg-August-Universität Göttingen have gained new insights into specific enzymes that effect the specialisation of fungal cells. Analysing the microscopic fungus Sordaria macrospora, ...

Breaking through insect shells at a molecular level

With their chitinous shells, insects seem almost invulnerable – but like Achilles' heel in Greek mythology, their impressive armor can still be attacked. Researchers at the universities of Bonn and Leipzig studied fruit ...

Walking fish reveal how our ancestors evolved onto land

About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial ...

A glimpse at the rings that make cell division possible

Forming like a blown smoke ring does, a "contractile ring" similar to a tiny muscle pinches yeast cells in two. The division of cells makes life possible, but the actual mechanics of this fundamental process have proved difficult ...
