A combination of experimental and theoretical analysis identifies body size-dependent energy storage as the physiological cause of 3/4-power law scaling of the metabolic rate in planarians.

Rat brains mature to increase metabolic connectivity between network components and establish energy efficiency in the midline structures from childhood to early adulthood.

A riboswitch class has been discovered for phosphoribosyl pyrophosphate, the biochemical precursor of nucleotides, and this novel RNA sensor commonly operates in tandem with a guanine aptamer to function like a Boolean logic gate.

The Acyl-CoA binding domain-containing 7 (Acbd7) gene is expressed in the hypothalamus, encodes a peptide that suppresses appetite, increases metabolic rate and interacts with the leptin-melanocortin system.

Parasitic helminths infect over a billion humans and use unusual anaerobic metabolism that needs a rare electron carrier, Rhodoquinone (RQ), whose synthesis requires the kynurenine pathway of tryptophan degradation.

The RNA binding protein Sam68 links a key metabolic route to the neural stem cell fate in the developing mouse brain.

With replicative age, S. cerevisiae shifts from a fermentative towards an unusual respiratory metabolism, accompanied by a decrease in growth and glucose uptake rate.

Transcriptomics is shedding new light on the relationship between photosynthetic algae and salamander eggs.

Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.
