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.

Small Regulatory RNAs May Sharpen Spatial Expression Patterns

linked profile(s): hlevine
submitted by: apryl
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis,...

Contributions of Ibn Al-Nafis to the progress of medicine and urology. A study and translations from his medical works

submitted by: rabie
This primary-source study of 4 medical works of the 13th century Muslim scholar Ibn Al-Nafis confirmed that his Kitab Al-Mujaz Fi Al-Tibb was authored as an independent book meant to be a handbook for medical students and practitioners not as an epitome of Kitab Al-Qanun of Ibn Sina as thought by recent historians. His huge medical encyclopedia, Al-Shamil, represents a wave of intense scientific activity that spread among the scholars of Cairo and Damascus following the massive destruction...
