  Why is Sex Fun? - The Evolution...

  To us humans, the sex lives of many animals seem weird. In fact, by comparison with all the other animals, we are the ones with the weird sex lives. How did that come to be?Just count our bizarre ways. We are the only social species to insist on carrying out sex privately. Stranger yet, we have sex at any time, even when the female can't be fertilized (for example, because she is already pregnant, post-menopausal, or between fertile cycles). A human female doesn't know her precise time of fertility and certainly doesn't advertise it to human males by the striking color changes, smells, and sounds used by other female mammals.  
  Why do we differ so radically in these and other important aspects of our sexuality from our closest ancestor, the apes? Why does the human female, virtually alone among mammals go through menopause? Why does the human male stand out as one of the few mammals to stay (often or usually) with the female he impregnates, to help raise the children that he sired? Why is the human penis so unnecessarily large?  
  There is no one better qualified than Jared Diamond—renowned expert in the fields of physiology and evolutionary biology and award-winning author—to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status.

  A time like no other is upon us as artificial intelligence grows. The time will soon come where humanioid robots roam among us that are indistiguishable from a human. The time for warning bells is now as we leap into the ethical ramifications of such development as well as the sociological impact such involvements will result. We must be ready for the robot revolution. Be prepared to train your robots in good ways so that they will learn what is best for not only the individual, but also all of society. And what is not good for society? Psychiatry...

  As you age, you may find yourself worrying about your memory. Where did I put those car keys? What time was my appointment? What was her name again? With more than 41 million Americans over the age of 65 in the United States, the question becomes how much (or, perhaps, what type) of memory loss is to be expected as one gets older and what should trigger a visit to the doctor.Seven Steps to Managing Your Aging Memory addresses these key concerns and more, such as:● What are the signs that suggest your memory problems are more than just part of normal aging?● Is it normal to have concerns about your memory?● What are the markers of mild cognitive impairment, dementia, Alzheimer's, and other brain diseases?● How should you talk about your memory concerns to your doctor? What should your doctor do to evaluate your memory?● Which healthcare professional(s) should you see? What medicines, alternative therapies, diets, and exercises actually work to improve your memory? What other resources are available when dealing with memory loss?

  Search for Exoplanets The: The...

  While modern technology has helped astronomers view the furthest reaches of the Solar System, it has also allowed scientists to start discovering planets orbiting distant stars. To make it easier to assess the relative mass and size of the new planets being discovered, scientists give these measurements as multiples of those properties for either Jupiter or Earth. In other words, if the planet is the same mass as Jupiter, then this measure would be listed as 1.0 MJ. If it were three times the mass of Earth, then it would be listed as 3.0 MEarth. The sizes of exoplanets are frequently given by expressing their radii as multiples of Jupiter’s radius or as multiples of Earth’s radius, RJ and REarth, respectively.  
  	Of course, given the immense distances involved, detecting exoplanets has always been hard, even to this day. The variations of light that might be evidence of an exoplanet can be caused by other phenomena, and separating the false positives from the actual detections is part of the rigor required by modern planet hunters. For example, in July 1988, a Canadian team led by astronomers Bruce Campbell, Gordon Walker, and Stephenson Yang discovered persistent indications that a planet orbited the primary star in the Gamma Cephei system, 44.98 light-years (13.79 parsecs) from the Earth. Though the technique they used was successfully employed in many subsequent discoveries, the quality of their data was insufficient for others to verify as unequivocally the result of an extrasolar planet. For reasons of poor data quality, the claimed discovery of Gamma Cephei Ab was retracted in 1992.  
  	The first confirmed discovery of an exoplanet involved a system that surprised most planet hunters. While most astronomers had been looking to find planets orbiting stars in the main sequence (between infancy and old age) or in their old age (giant phase), the first confirmed planets were found to orbit a dead star.
