Karl Oskar Illmensee studied the cloning [2] and reproduction of fruit flies, mice, and humans [3] in the US and Europe during the twentieth and twenty-first centuries. Illmensee used nuclear transfer techniques (cloning [2]) to create early mouse [4] embryos from adult mouse [4] cells, a technique biologists used in later decades to help explain how embryonic cells function during development....

and time. However, it’s not all about machines taking over from field workers. Technology can also help to get more people involved with field work in ecology and conservation. The Earthwatch Institute (www.earthwatch.org), for instance, supports a project called My Tree Tracker, based on a smartphone app encouraging volunteers to keep an eye on the growth and health of the trees in their citie...

andré gide fut un écrivain qui avait, durant sa longue carrière littéraire, touché nombre de genres littéraires, notamment le roman, le journal, la correspondance, le souvenir, le carnet, le récit de voyage, etc. mais, cette étude, qui est fondée sur son journal (1889 à 1939, et 1939 à 1949), est consacrée à une partie presque inconnue de ses productions littéraires: ses traductions. au fait, o...

Subject of the study.?A good many surveys of physical conditions and health in Indian children have been carried out (Aykroyd and Rajagopal, 1936; Aykroyd, Madhava and Rajagopal, 1938; Chatterjee, 1938; Mitra, 1939; Singh, 1939; Shourie, 1939; Wilson, 1939; Wilson and Mitra, 1938). However, the population of India is so heterogenous that it may be of value to add, to the surveys already carried...

The Xenopusmid-blastula transition (MBT) marks the onset of largescale zygotic transcription, as well as an increase in cell cycle length and a loss of synchronous cell divisions. Little is known about what triggers the activation of transcription or how newly expressed genes interact with each other. Here, we use high-resolution expression profiling to identify three waves of gene activity: a ...
