In a new study [1], researchers have identified the reason why cells become defective when they grow too large and why protein creation fails when cells grow larger than their original healthy size, as is typically seen in aged and senescent cells.

They demonstrate that in enlarged yeast and human cells, RNA and protein biosynthesis does not scale in proportion to the additional cell size, which then leads to a dilution of the cytoplasm. This phenomenon is also present in senescent cells, which display similar traits to those of large cells.

The research team concludes that the maintenance of a cell type-specific DNA-to-cytoplasm ratio is essential for the majority of cellular functions, and when cellular growth changes this ratio, it encourages cells to become senescent.

To many of us, the great white shark is a mysterious and scary creature from the deep – but now it’s a little less mysterious. A team of scientists has sequenced the entire genome of the great white shark, revealing a few clues as to how these animals are so good at healing wounds and resisting cancer.

The Centers for Disease Control and Prevention just issued a new update to its ongoing investigation of a months-long Salmonella outbreak linked to turkey products. The update, which is the first since mid December of last year, adds over 60 new confirmed cases of Salmonella infection to the 200+ cases that were already logged.

A total of 279 cases have now been confirmed across 41 states, with over 100 hospitalized patients and one death resulting from the outbreak. Unfortunately, the bulletin brings more bad news as there’s still been no confirmed source of the Salmonella, and the investigation remains active.
