This week a ground-breaking new resource for scientists went live. More than twenty paleontologists, molecular biologists, and computer programmers from five different countries designed and contributed to a new open-source database that stores carefully reviewed fossil data and makes it accessible worldwide.

So-called silent DNA mutations earned their title because, according to the fundamental rules of biology, they should be inconsequential.

The robust defenses that yeast cells have evolved to protect themselves from environmental threats hold lessons that can be used to design computer networks and analyze how secure they are, say computer scientists at Carnegie Mellon University.

Rainbow Trout Genome Sequenced By International Team Of Researchers

A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice.

Intracellular ABC Transporters Allow Leaf Beetle Larvae To Accumulate Defensive Substances When Feeding
2013-12-09 11:58:38

Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae.

Convergent evolution – the evolution of similar traits in drastically different types of creatures – is widespread not just at the physical level but also at the genetic level, according to new research published in this week’s edition of the journal Nature.
