Scientists teach old worms new tricks

Model organisms such as yeast, fruit flies, and worms have advanced the study of genomics, eukaryotic biology, and evolution. An important resource for any model organism is a near-complete reference genome from which a multitude ...

New leaf shapes for thale cress

Anyone who looks at their bowl of salad or at their garden can see how different the shapes of leaves can be. Spinach leaves, for example, have smooth edges and are comparatively simple in form, while parsley leaves are deeply ...

Spatial DNA organization forms first, then the rest

The fundamental organization of the DNA in active and inactive compartments arises immediately after fertilization of the oocyte, even before genes are activated. This was discovered by researchers from the Hubrecht Institute ...

Researchers create most complete model of complex protein machinery

Environmental conditions, lifestyle choices, chemical exposure, and foodborne and airborne pathogens are among the external factors that can cause disease. In contrast, internal genetic factors can be responsible for the ...

Life in evolution's fast lane

Most living things have a suite of genes dedicated to repairing their DNA, limiting the rate at which their genomes change through time. But scientists at Vanderbilt and University of Wisconsin-Madison have discovered an ...

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 ...

Key acid-activated protein channel identified

Johns Hopkins researchers have discovered a long-sought protein, the proton-activated chloride channel (PAC), that is activated in acidic environments and could protect against the tissue-damaging effects of stroke, heart ...
