Latest molecular evolution Stories
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.
Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens a window into how vertebrates evolve.
From time to time, living cells will accidentally make an extra copy of a gene during the normal replication process.
A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice.
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.
One of the most important processes in the life of cells is genome replication, which consists of making exact copies of the DNA in order to pass it on to their offspring when they split.
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.
- The deadly nightshade, Atropa Belladonna, which possesses stupefying or poisonous properties.
- A sleeping-potion; a soporific.
- To mutter deliriously.
