Just what computer scientists want - dumb jocks getting all of the credit for artificial intelligence.

Or maybe computer scientists are simply letting football players think they matter, and they are really just data.

For artificial intelligence to get out of its 20-year rut, a computer has to be able to observe a complex operation, learn how to do it, and then optimize those operations or accomplish other related tasks. What if a computer could watch video of football plays, learn from them, and then design plays and control players in a football simulation or video game?  

Our solar system, with planets over a range of sizes and moving in near-circular paths, seems to be unusual, according to a model in t Monthly Notices of the Royal Astronomical Society which finds that forming planetary systems may be knocked around by crashes with nearby clumps of material, leading to systems where planets have highly inclined orbits and where the smaller - and potentially habitable - worlds are thrown out completely.

Researchers  have developed an inexpensive way to grade the ethanol potential of perennial grasses at the biorefinery's loading dock - the first use of near-infrared sensing (NIRS) to measure 20 components in switchgrass biomass that determine its potential value to biorefiners. These components include cell wall sugars, soluble sugars and lignin. With this information, 13 traits can be determined, including the efficiency of the conversion from sugars to ethanol.

This is the first use of NIRS to predict maximum and actual ethanol yields of grasses from a basic conversion process. This capability already exists for corn grain using NIRS.
As health care costs continue to rise and more people want more services for less money, it will be important that doctors engage in evidence-based medicine. 

The Centers for Disease Control and Prevention (CDC) have determined that the majority of primary care providers continue to recommend annual cervical cancer screening, though cervical cancer screening guidelines recommend a combination of a Papanicolaou test and an HPV test, known as an HPV co-test, for women 30 years of age and older. 
Cancer, diabetes, stroke and transplant patients can all get benefit from one common thing; frog skin.

An international research project is collecting proteins from our amphibian friends (no frogs were harmed in the writing of this article or in the research) and adding to a growing bank of biological data needed to build up our understanding of the naturally occurring medicines in frogs.

They have already found that the peptides (mini-proteins) collected from the Waxy Monkey Frog and the Giant Firebellied Toad can be used in a controlled and targeted way to regulate 'angiogenesis', the process by which blood vessels grow in the body.  
University of Alberta researcher David Bressler has an idea for the future of recycling.

Using throwaway parts of beef carcasses that were sidelined from the value-added production process after Mad-cow disease (bovine spongiform encephalopathy or BSE) damaged the Canadian beef industry in 2003, Bressler has collaborated with industry, government and other researchers to forge cattle proteins into heavy-duty plastics that could soon be used in everything from car parts to CD cases.
