Divided They Conquer – tRNAs Are Segmented Into Fragments In a Manner That Depends on Race, Gender and Tissue, A Finding That May Impact Future Studies Of Disease

The study reports on a newly discovered category of tRNA fragments as well as shows that all tRNAs are rich sources of very diverse short molecules whose characteristics depend on a person’s gender, population, and race and differ according to tissue and disease type.

Cellular Sentinel Prevents Cell Division When the Right Machinery Is Not in Place

For cell division to be successful, pairs of chromosomes have to line up just right before being swept into their new cells, like the opening of a theater curtain. They accomplish this feat in part thanks to structures called centrioles that provide anchors for the curtain’s ropes. Researchers recently learned that most cells will not divide without centrioles, and they found out why: The protein p53 monitors centriole numbers to prevent potentially disastrous cell divisions.

Researchers at the University of Georgia have a message for Southern tree farmers worried about unexplainable pine tree deaths: Don’t panic. A new study published in Forest Ecology and Management analyzed growth in thousands of pine tree plots across the Southeast and indicates that “southern pine decline” isn’t happening on a large scale.
