Body builders — planarian worms point the way to understanding tissue regeneration
Scientists at The University of Nottingham have discovered the gene that enables an extraordinary worm to regenerate its own body parts after amputation — including a whole head and brain.
Their research into the Planarian worm is another piece in the scientific jigsaw that could one day make the regeneration of old or damaged human organs and tissues a real possibility.
Winter of Discontent
Kansas history holds many harrowing storm stories, none more tragic than that of 10-year-old Dean Thomas. His untimely death eventually led to a donation of his childhood belongings, including these overalls.
Le développement de l'intelligence chez l'enfant - Olivier HOUDE (video)
Conférence du 25 janvier 2000 par Olivier Houde.
D'où détenons-nous ce précieux trésor qu'est notre intelligence ? Pour René Descartes (1596-1650), la réponse était simple : Dieu a déposé dans notre esprit, dès la naissance, des idées logico-mathématiques claires et distinctes, noyau de l'intelligence humaine. Quatre siècles plus tard, en ce début 2000, quelle réponse apporte la science à cette question ?
La Cité de Dieu, après-demain ? (audio)
Quand Rome est mise à sac le 24 août 410, des voix se lèvent s’interrogeant sur les raisons d’un tel désastre et sur le devenir de Rome. Demain qu’adviendra t-il de la Roma aeterna ? Déconcerté par ce pillage et soucieux d’éclairer les jugements, Saint Augustin décide alors de mener à bien son projet déjà ancien de composer une fresque théologique.
Il compose ainsi La cité de Dieu, œuvre qui oppose la cité terrestre et la cité céleste et qui
Images de la mort dans la B.D. et la peinture (audio)
A une époque où la mort est devenue une « valeur marchande » pour les médias et où l’intérêt pour le fait divers se fait toujours plus vif, Pierre Christin nous donne un aperçu de la représentation visuelle de la mort dans l’art pictural et photographique et dans la bande dessinée. Occultée parfois, crainte le plus souvent, la mort est un thème récurrent dans l’art et sa représentation évolue en même temps que les croyances et les sociétés.

The Law of Cosines
One method for solving for a missing length or angle of a triangle is by using the law of cosines. The law of cosines, unlike the law of sines, is similar to the Pythagorean theorem, but it works for all triangles, not just right triangles. In order to understand how to use the law of cosines effectively, one must understand the cosine function and inverse trigonometric functions. (1:21)

Graphing Radical Equations Using Shifts
This video describes, when graphing radical equations using shifts, how adding or subtracting a constant that is not in the radical will shift the graph up (adding) or down (subtracting). Adding or subtracting a constant that is in the radical will shift the graph left (adding) or right (subtracting). Multiplying a negative constant by the equation will reflect the graph over the x-axis. Multiplying by a number larger than one increases the y-values. (7:12)
Estimating Square Roots
When a radical is not a perfect square (1, 4, 9, 16, …), estimating square roots is a valuable tool. This video describes how to estimate the value of a radical between two consecutive integers by finding the two perfect squares that are slightly less and slightly more than the radicand. Also, remember that negative numbers do not have a real number square root. (2:28
