Key Highlights
•
A specific genetic variant in a region that controls the CCND3 gene has been linked to a reduced risk of malaria. This discovery highlights a new potential genetic factor for natural resistance to a major global infectious disease.

Using a technique to silence specific chromosome copies, researchers found that in cells with an extra chromosome 21, only one copy of the RWDD2B gene is typically active, not all three. This shows that an individual’s unique genetic variations can override simple gene dosage, which is crucial for understanding conditions like Down syndrome.

A new AI tool called EnDeep4mC can accurately predict where a specific chemical tag (4mC) will be placed on DNA, a key process for cell function. This tool outperforms existing methods and reveals that bacteria and more complex organisms use different genetic “rules” for this tagging, offering insights into evolution.

When plant cells are stressed, they have a new quality-control system that separates damaged parts of the nucleolus (a cell’s protein factory) from healthy parts during division. This ensures that new cells inherit a refreshed, functional nucleolus, which is vital for cell health and survival under pressure.
