How chromosomes change their shape during cell differentiation

The human genome is made up of 46 chromosomes, each of which has a length of about 100 to 200 million base pairs, the building blocks of the DNA double helix. Even during interphase, the period in between the cell division ...

Scientists find longevity biomarkers

An international group of scientists studied the effects of 17 lifespan-extending interventions on gene activity in mice and discovered genetic biomarkers of longevity. The results of their study were published in the journal ...

Map of malaria behavior set to revolutionize research

The first detailed map of individual malaria parasite behaviour across each stage of its complicated life cycle has been created by scientists. Researchers at the Wellcome Sanger Institute and their collaborators used advanced ...

Scissors get stuck—another way bacteria use CRISPR/Cas9

In biotech these days, CRISPR/Cas9 is a hot topic, because of its utility as a precise gene editing tool. Before humans repurposed it, CRISPR/Cas9 was a sort of internal immune system bacteria use to defend themselves against ...

A 'biomultimeter' to measure RNA and protein production in real-time

Builders of genetic circuits face the same quandary as builders of digital circuits: testing their designs. Yet unlike bioengineers, engineers have a simple and universal testing tool—the multimeter—that they can touch ...
