Researchers at the Johns Hopkins University School of Medicine have determined how the protein Botch regulates the activity of the development-related protein Notch. The results, which were published online April 24th, 2014 in the journal Cell Reports, could have significant implications for our understanding of mammalian development.

Four teenage girls born with Mayer-Rokitansky-Küster-Hauser syndrome, a condition that causes the underdevelopment or complete absence of the vagina, cervix and uterus, have successfully received vaginas grown from their own cells. The vaginal development, implantation and incorporation were reported on April 10 in The Lancet by researchers from the Wake Forest Baptist Medical Center.

Researchers at the Large Hadron Collider in Geneva, Switzerland have confirmed the existence of Z(4430). This particle, thought to be an elusive form of matter called a tetraquark, does not conform to any other known models of matter. This Z(4430) discovery came from the Large Hadron Collider beauty (LHCb) collaboration, a multinational research project led by researchers from Syracuse University.

Inherent in its Latin root tumere, meaning “to swell,” a tumor describes an abnormal growth of cells. It is a bodily excess, something indispensible, often necessarily, for proper bodily functions. This modern conception of tumorous growths leaves no room for functional structures in the abnormal mass. Imagine the surprise, then, when a team of doctors at Johns Hopkins Hospital found fully grown teeth in the brain tumor of a four-month-old child.

Groundbreaking research on stem cells presented by Haruko Obokata of the RIKEN Center for Developmental Biology has recently come under serious scientific scrutiny. Concerns about the research data and the reproducibility of the results have prompted Nature and the RIKEN Center to launch investigations into Obokata’s original work.

Embryonic stem cells. My mom told me not to treat them like playthings and Bush told me not to use them in my research. Scientifically, embryonic stem cells are the holy grail of developmental biology. These cells are pluripotent, meaning they can adopt any cell type present in an adult organism. This unrestricted potential allows scientists to test developmental processes in ways completely impossible with differentiated cells. Moreover, embryonic stem cells have important medical implications, as they can be used in regenerative medicine.

Mondays just got better. According to a study published Oct 28 in JAMA Internal Medicine, smokers are more likely to consider giving up their habit on Monday than any other day of the week. This conclusion is based on Google search data: the researchers monitored searches on quitting smoking conducted in English, French, Chinese, Portuguese, Russian, and Spanish between 2008 and 2012. Search frequencies were the higher early in the week, Monday being the clear winner. The number of searches on Mondays was 25 percent higher than the combined average of searches on Tuesday through Sunday. The pattern was consistent across all languages.

What is art? Tolstoy said it is a means of union among men. Fellini thought it was autobiography. Oscar Wilde defined it as the most intense mode of individualism the world has seen. Lexus, trying its hand at aesthetic philosophy, thinks art is motion.

Electrical stimulation of the heart is a common phenomenon. If you are CPR/AED certified, you’ve practiced saving someone’s life using a defibrillator. If you know anyone with a heart problem, chances are they have a pacemaker or have talked to their doctor about getting one. Both defibrillators and electrodes use direct electrical stimulation to correct cardiac arrhythmias.
