Anyone who have been working in a multidisciplinary science project knows how hard it is to establish coherent dialogs that make sense and are productive for all participants. Scientists from each discipline tend to form their own 'head' creating an unmanageable n-headed troll. Implementation of the Global Earth Observation System of Systems (GEOSS) is such a project. In this article I discuss how we can use new media to facilitate an effective dialog that connects all GEOSS science and technology stakeholders, the citizens that will both build and use GEOSS.

Human embryonic stem cell research is limited in the US and Europe but creative researchers have made significant advances  using the existing hESC lines allowed under US federal guidelines along with induced pluripotent stem cells and adult stem cells.

Scientists at Monash University's Immunology and Stem Cell Laboratories (MISCL) say they can now make precursor human stem cells from healthy adult kidneys without working on human embryos at all.

Thrombolytic agents, commonly called "clot-busting" drugs, are frequently used in the treatment patients with blood clots in the lungs but a new study says clot-busting drug are no more effective than traditional blood thinners for the majority of the patients who get them. Thrombolytic agents also appear to increase the risk of death in patients with normal blood pressure.

Diseases such as retinitis pigmentosa (RP) and age-related macular degeneration (AMD) are the leading causes of incurable blindness in the western world. In these diseases, retinal cells (photoreceptors) begin to die and limit the eye's ability to capture light and transmit information to the brain. Retinal cells, like other cells of the central nervous system, have limited capacity for endogenous regeneration. 

Now scientists say they can regenerate large areas of damaged retinas and improve visual function using IPS cells (induced pluripotent stem cells) derived from skin.    IPS cells became well-researched, along with ordinary stem cells, due to limitations in the US and Europe regarding use of human embryonic stem cells.   

The presentation of data is a very rich subject, on which there is a whole lot to discuss, even by restricting to the issues relevant to our dear field of experimental high-energy physics. Usually too little thought is given to it, even by expert researchers, so I thought that maybe today I would offer here some ideas on one very basic issue, the one of how to choose the width of the bins of a histogram.
