From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Usborne Young Reading: Series Two

open access: yes, 2003
This fine little book builds off of Usborne's excellent 1982 publication by the same name. The text has been changed to a significant extent. The departing country mouse had said I'm gong back to the country where life is quiet but safe.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The Story Starters

open access: yes, 1985
This eight-page pamphlet combines rhyming quatrains with illustrations that look as though they include stained glass. They are quite attractive! Story Starters seems to be a series that helps children with their first steps in reading. The back cover

Prospecting the protein design landscape

open access: yesFEBS Letters, EarlyView.
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The Lion Grown Old

open access: yes, 1960
This sixteen-page pamphlet about 7 x 7½ has lively illustrations inside covers that show a good deal of wear. From the title-page on, the lion has a pince-nez that is slipping off of his nose. He acquires bandages on his paws and body as he goes along.

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Fables d'Ésope

open access: yes, 1933
This book seems to be one-quarter the size of the English version of Orr's book, for which I have guessed a date of 1927, but it is really two-thirds of its size, having 60 pages to the 96 pages of the English edition. The paper is thinner here.
