In a new study published in the online-open access journal PLoS ONE, Per Christiansen at the Zoological Museum in Copenhagen, Denmark, reports the finding that the evolution of skull and mandible shape in sabercats and modern cats were governed by different selective forces, and the two groups evolved very different adaptations to killing.

The cat family comprises some of the most specialized carnivores in the history of mammals, all exclusively eating flesh. The cat family consists of two major sub-groups: the feline cats (including all modern species) and the sabertoothed cats (which are all extinct). Skeletons from the two groups look broadly similar, but their skulls are often remarkably different, and suggest that members of the two groups underwent radically different adaptations to predation during the course of evolution.

Physicists from the University of Granada and University of Valencia, analyzing data sent by the Huygens probe from Titan, say they have “unequivocally” proved that there is natural electrical activity on Titan, the largest of Saturn's moons.

Scientists generally believe that the probability of organic molecules, precursors of life, being formed is higher on planets or moons which have an atmosphere with electrical storms.

Juan Antonio Morente, from the Department of Applied Physics at the University of Granada, told Servicio de Informacion y Noticias Cientificas(SINC) that Titan has been considered a “unique world in the solar system” since 1908 when, the Spanish astronomer, José Comas y Solá, discovered that it had an atmosphere, something non-existent on other moons.

Its something that every coach and every athlete of every sport is searching for... the EDGE. That one training tip, equipment improvement, mental preparation or tactical insight that will tip the game towards them. The body of knowledge that exists today in each sport is assumed, with each competitor expected to at least be aware of the history, beliefs and traditions of their individual sport. But, if each team is starting with the same set of information then the team that takes the next step by applying new research and ideas will capture the edge.

To me, that is what sport science is all about. The goal is to improve sports performance by imagining, analyzing, experimenting, testing, documenting and training new methods to coaches and athletes.
