How cells are able to turn

Researchers have long wondered how our cells navigate inside the body. Two new studies, in which Lund University researcher Pontus Nordenfelt has participated, have now demonstrated that the cells use molecular force from ...

Fanconi anemia: Insight from a green plant

Fanconi anemia is a human genetic disorder with severe effects, including an increased risk of cancer and infertility. Work in animal systems has identified many factors involved in Fanconi anemia and showed that these factors ...

Packing a genome, step-by-step

Genome folding now has a playbook. A new step-by-step account spells out in minute-time resolution how cells rapidly pack long tangles of chromosomes into the tiny, tightly wound bundles needed for cell division. Cells reel ...

A new, dynamic view of chromatin movements

In cells, proteins tightly package the long thread of DNA into pearl necklace-like complexes known as chromatin. Scientists at EPFL show for the first time how chromatin moves, answering longstanding questions about how its ...

Snapshot of DNA repair

DNA is like the computer code of the body, and it must be preserved for our bodies to survive. Yet, as cells grow and change, DNA is vulnerable to defects, especially double strand breaks (DSBs). In fact, DSBs regularly occur ...

Secretin protein with a crown

Bacteria are consummate survivalists. They are aided in this by their ability to assimilate DNA from their surroundings, which allows them to constantly acquire new characteristics. Researchers at the Max Planck Institute ...

The nanoscopic structure that locks up our genes

For decades, scientists could only speculate about the shape of heterochromatin, a type of chromatin that consists of tightly packed DNA and proteins. Recently, however, researchers from the Okinawa Institute of Science and ...

Scientists make cells that enable the sense of touch

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have, for the first time, coaxed human stem cells to become sensory interneurons—the cells that give us our sense of ...

How good bacteria control your genes

Scientists from the Babraham Institute near Cambridge in collaboration with colleagues from Brazil and Italy have discovered a way that good bacteria in the gut can control genes in our cells. The work, published today (9th ...

First 'cell map' of 20,000 cells in mammalian embryo

Scientists at the Wellcome—MRC Cambridge Stem Cell Institute have used cutting-edge technology to profile over 20,000 individual cells to produce the first 'cell map' describing all the major cell types present at the early ...

Finding form by folding

Ribosomes are the organelles responsible for protein synthesis in cells. LMU researchers have now dissected early steps in their assembly and visualized how their RNA components fold correctly and find their places in the ...
