New research has uncovered a tiny protein that, when it breaks down, leads to cancer. This useful protein attaches to DNA in certain places and serves as a marker or “fence post.” These fence posts keep certain zones of DNA accessible to the cell regulatory mechanisms that activate gene expression to produce other proteins.

Computer programs are written in coded computer languages, and sometimes the same piece of code can be reused in different programs to perform new functions. This way, programmers save time and energy by not having to invent new code. For this to work, however, the programmer must intentionally specify how each program will use the recycled code to perform the designated functions.

Salmonella bacteria became a health threat relatively recently, when chicken eggs were infected by the migration of the bacteria from chickens’ digestive organs to their reproductive organs. Geneticists are working to characterize differences between the harmful and innocuous strains of Salmonella.

One common question asked of creation scientists is “If all mankind descended from two humans, then where did all the ‘races’ come from?” New research, published in the journal Evolution no less, supports the creation-based answer to this question.

Evolutionary scientists often use results derived from molecular biology dating methods (based on DNA sequence similarities) to bolster their assumptions that some related organisms may have diverged millions of years ago.
