Evolution in Action: Lizard Moving From Eggs to Live Birth Evolution has been caught in the act, according to scientists who are decoding how a species of Australian lizard is abandoning egg-laying in favor of live birth. Along the warm coastal lowlands of New South Wales (map), the yellow-bellied three-toed skink lays eggs to reproduce. But individuals of the same species living in the state's higher, colder mountains are almost all giving birth to live young. Only two other modern reptiles—another skink species and a European lizard—use both types of reproduction. (Related: "Virgin Birth Expected at Christmas—By Komodo Dragon.")
Top 10 Most Influential Scientists - Top 10 Lists Humans This is part one of what will be a two part series on the most influential scientists in history. While these are not technically the “greatest” scientists, there is bound to be some overlap as the contributions that many of these men and women made to science are among the most important.

God, Humanity and the Cosmos Topic: Darwin and the Term ‘Evolution’ Darwin and the Term ‘Evolution’ Darwin did not use the noun ‘evolution’ to describe his theory in the Origin; in fact he only used the word ‘evolved’ once in his book. The pre-Darwinian connotations of the word concerned a predictable unfolding of possibilities, as seen for example in the processes of embryonic development. Darwin would not have chosen the word because his theory is based upon variants which occur in an undirected way, and are then selected for or against by an environment which may also alter irregularly, not on a ladder of progress. A Sense of Scale By Glenn Elert Posted 01.08.08 NOVA At roughly minus 460°F, absolute zero is abysmally cold, yet at least we can imagine it. Being only a few hundred degrees below zero, it's in the realm of something we can put our minds around. This is not true of the opposite of absolute zero, the theoretical highest possible temperature.
Serious Games Bring Immersive Astronomy To Science Classrooms Serious Games for a high tech space-simulation experience Via: Edutopia - Virtual Universe: Students Use Technology to Reach for the Stars by Bilen Mesfin Full Article Evolutionary psychology Evolutionary psychology (EP) is an approach in the social and natural sciences that examines psychological traits such as memory, perception, and language from a modern evolutionary perspective. It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and immune system, is common in evolutionary biology. Some evolutionary psychologists apply the same thinking to psychology, arguing that the mind has a modular structure similar to that of the body, with different modular adaptations serving different functions. Evolutionary psychologists argue that much of human behavior is the output of psychological adaptations that evolved to solve recurrent problems in human ancestral environments. The adaptationist approach is steadily increasing as an influence in the general field of psychology.

Concord: The Concord Consortium, 2010, September 26. Electric fish diverging Carl Hopkins Although these fish look alike and have the same DNA genetic makeup, they have very different electrical signals and will only mate with fish that produce the same signals. Cornell researchers believe that these different electrical signals are the fishes' first step in diverging into separate species. Immersive Learning Simulations ForgeFX has been a proud content development partner for Pearson Education for over 10 years. Developing over 100 simulation-based training programs and applications, across a number of different subjects and curricula, ForgeFX helps Pearson Education deliver digital learning products that transform students from passive audience members, to active participants in the learning process. 3D Wave Simulator This real-time 3D wave simulator demonstrates the connection between wind speed and ocean particle motion depth. The application helps students visualize how waves are the forward movement of water, due to the oscillation of water particles by the frictional drag of wind over the surface.
Mathematical and theoretical biology Mathematical and theoretical biology is an interdisciplinary scientific research field with a range of applications in biology, biotechnology, and medicine. The field may be referred to as mathematical biology or biomathematics to stress the mathematical side, or as theoretical biology to stress the biological side. It includes at least four major subfields: biological mathematical modeling, relational biology/complex systems biology (CSB), bioinformatics and computational biomodeling/biocomputing. Mathematical biology aims at the mathematical representation, treatment and modeling of biological processes, using a variety of applied mathematical techniques and tools. It has both theoretical and practical applications in biological, biomedical and biotechnology research. For example, in cell biology, protein interactions are often represented as "cartoon" models, which, although easy to visualize, do not accurately describe the systems studied. Importance
