Tumour cords' growth in a vascular network

submitted by: sast
Evolutions of oxygen concentration and formation of hypoxic zones during tumour growth in the vascular network . This simulation was produced with an experimental modification to the model, where vessels are oxygen sources inside the simulation domain, cells do not switch to anaerobic metabolism in this simulation.

ATP deficit in oxygen-limited tumour cord growth (FF++)

submitted by: sast
This is a simulation of tumour cord growth , where cells suffer from hypoxia (energy deficit shown with colour). The tumour grows along the blood vessel (coincides with x -axis). Red line shows the position of the tumour–host interface. This particular simulation was programmed in FreeFEM++ out of curiousity. The source code for simulation may be found at http://code.google.com/p/cord . This video reflects work in progress and may be different from the final results .

Spiranthes praecox Rich.

submitted by: Timothy M. Jones
Spiranthes praecox, greenvein lady's tresses, is an orchid native to eastern North America, from eastern Texas to New Jersey. Though many members of the genus are difficult to identify, this species is readily distinguished by the green veins on the lip of the flower. A yellow veined form is also known (C.J. Sheviak and P.M. Brown. In: Flora of North America. Vol 26, 2002). Plant 15-80 cm tall; with mostly linear leaves (1 - 5 mm wide) often hidden in leaf litter; inflorescence...

open genius: strumento per una scienza libera

submitted by: atnp lab

In this presentation, Andrea Gaggioli describes crowd-funding as a possible strategy to cope with the lack of investments in research, as well as to increase democratization in the sciences. Projects seeking funding could be stored in an online repository. Each project would include a description of its objectives, duration, and requested contribution. Investors (either people or funding agencies) could decide which projects to fund.
