Ploidy‐Dependent Response to Anticancer Drugs of Human Embryonic Stem Cells

Cell Proliferation, EarlyView.
Using isogenic hESCs, differing only in their ploidy level, we show the effect of ploidy on the resistance to anticancer drugs. We demonstrate that polyploidy, by itself, confers sensitivity to chemotherapies, leading to higher apoptosis and delayed proliferation, while the loss of p53 reverses the phenotype, demonstrating higher resistance.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

The circulation and distribution of classical Greek coinage

The Economic History Review, EarlyView.
Abstract From a sample of the most prominent Greek city‐states, data involving a total of 999 hoards and 160,007 coins from 550 to 300 BC were collected to discern the relative magnitudes, consistency of issue, and distribution of Classical Greek coinages.

A lipid‐sensitive food choice behavior influences aging outcomes from a longevity‐promoting diet

The FEBS Journal, EarlyView.
C. elegans are exposed to a variety of bacteria in their natural environment and must be able to distinguish between beneficial and detrimental food sources. We show that C. elegans exposed to the bacterium from their natural habitat, Methylobacterium, disrupts lipid homeostasis, causing worms to avoid this bacterial species and choose the laboratory ...

A comprehensive study on ferredoxin isoforms in the cyanobacterium Synechocystis sp. PCC 6803

The FEBS Journal, EarlyView.
Ferredoxins are small FeS cluster‐containing proteins that play a central role in distributing electrons within the cell. The cyanobacterium Synechocystis sp. PCC 6803 contains several ferredoxin isoforms and their biophysical properties (UV/Vis and EPR spectra, Em potential), expression patterns, and interactions with the electron donors photosystem I
