Genetics & Molecular Biology

There's a perception among some that it's a man's world and they get all the attention.   If you've ever been in a bar or a library or a baseball game, you know this is not true - have a woman…

A study of gene expression in chickens, frogs, pufferfish, mice and people has revealed surprising similarities in several key tissues. Researchers writing in BioMed Central's open access Journal of…

Genetic differences can influence one's risk of developing proteinuria, a condition that increases the risk of cardiovascular disease and chronic kidney disease (CKD), according to a study appearing…

Researchers say they have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on…

In parallel human and mouse studies, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss. The new gene, a microRNA, is a…

Researchers have reported that they have been able to determine the molecular structure of a plant photolyase protein that is surprisingly similar to two cryptochrome proteins that control the "…

A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart…

The problem of how to model a biological system has been staring me in the face every day in recent months, and I need a place to indulge in baseless speculation. So if you stick around here at…

Males and females across many animal phyla are genetically separate in that they inherit different sets of sex chromosomes.  As known, human females inherit two copies of X chromosomes while…

Geneticists have tackled a question that has perplexed humanity since the dawn of time: does love at first sight truly exist? Maybe, according to a study published in the April 2009 issue of the…
