Key Highlights
•
A landmark 1985 study first documented how viruses can force a cell’s protein-building machinery to “slip” and read genetic instructions in a different frame, a trick called programmed ribosomal frameshifting. This discovery opened the door to finding similar genetic recoding in more complex animals, including humans, revealing a new layer of gene regulation.

Researchers have developed DynaBench, a new dynamic dataset for testing how well computer models predict how two molecules, like a drug and its protein target, fit together. This tool provides more realistic, moving targets for simulations, which is crucial for improving the accuracy of virtual drug discovery and design.

When cells are stressed, a fungus uses a “chaperone” system to sort and segregate damaged parts of its nucleolus—the cell’s ribosome factory—from new, healthy material during cell division. This reveals a new quality-control mechanism for cleaning up a key cellular structure, which is especially important in cells with multiple nuclei.

The PP2A-B55α protein complex can switch the pathway used to break down the cancer-promoting protein c-Myc, solving a paradox in tumor biology. This finding clarifies a key regulatory mechanism in cell growth and could inform new strategies for targeting c-Myc in cancer treatments.

Scientists characterized a key enzyme, AmiA, that helps the sexually transmitted bacterium *Chlamydia trachomatis* divide by cutting its cell wall. Understanding this specific protein’s function is a step toward identifying potential new drug targets to treat this common and often asymptomatic infection.
