LOGO has been evolving in incremental steps for 40 years. This has resulted in steady progress but some regions of the space of all programming languages for children cannot be reached without passing through unacceptable intermediate designs. What are the ultimate aims of LOGO? What criteria and aesthetics should be used in determining which areas of the design space are most promising? What w...

Path planning technologies have rapidly improved over the last 10 years, but further integration is needed if pathfinding engines are to drive the behavior of even more realistic characters. This paper briefly outlines existing approaches for path planning and suggests scenarios where integration of information about character’s relationships could improve the quality of path planning in games.

Educating biologists and computational biologists in methods and analyses is an ever-growing challenge. The amount of data and tools available to the scientific community continue to grow, and with that, there is a growing need to teach how to get the most out of this information. The PLOS Computational Biology Education section was launched in January 2006 [1] to address this challenge, with t...

The need to train biologists in computational methods is greater than ever before. Recently, I asked an MIT Biology Professor if his newer graduate students were more knowledgeable in bioinformatics and computational biology than in past years. He hesitated and said he needed to think more about it; there wasn’t a clear answer. What is clear, however, is that most graduate students are computer...

Over the past decade, a plethora of new information has been reported regarding etiology, natural history, classification, and treatment options for lunate osteonecrosis. New disease classifications have been described based on advanced imaging determination of lunate viability as well as a cartilage-based arthroscopic classification. Here we review the newest literature regarding Kienböck dise...

The role of the orthogeriatrician has grown over the last few years. Orthogeriatrics was primarily involved in the care and management of fragility hip fractures, but has recently been expanded to provide specialist care to patients admitted with other various fractures, the spine, pelvis, appendicular, and those suffered from major trauma. There is also an increasing role for the orthogeriatri...
