POPSFuture Devices Could Power Themselves
There are other mechanisms other than "pushing" that can generate pressure waves to spark energy in piezoelectric materials. Imagine a self-powering cell phone, for instance, that never needs to be charged because it converts sound waves produced by the user into the energy it needs to keep running. Some night clubs in Europe now feature dance floors built with piezoelectrics that absorb and convert energy from footsteps in order to help power lights in the club. And a Hong Kong gym reportedly is using the technology to convery energy from exercisers to help power its lights and music. Tahir Cagin and his partners study the piezoelectric concept. For this project, they fine-tuned piezoelectric materials with nanoscale dimensions . Studying piezoelectrics in microscopic units is a relatively new endeavor, but a key step along the road toward inventing a self-powering cell phone and other portable, high-tech devices, which contain these minute components already.

POPSTop 10 Forecasts for 2009 and Beyond 6. Professional knowledge will become obsolete almost as quickly as it’s acquired. An individual’s professional knowledge is becoming outdated at a much faster rate than ever before. 7. The race for biomedical and genetic enhancement will-in the twenty-first century-be what the space race was in the previous century. 8. Urbanization will hit 60% by 2030. 9. The Middle East will become more secular while religious influence in China will grow. 10. Access to electricity will reach 83% of the world by 2030.

POPSSuperstruct Begins The human species has a long history of overcoming tremendous obstacles, often coming out stronger than before. Indeed, some anthropologists argue that human intelligence emerged as the consequence of the last major ice age, a period of enormous environmental stress demanding flexibility, foresight and creativity on the part of the small numbers of early Homo sapiens. Historically, those who have prophesied doom for human civilization have been proven wrong, time and again, by the capacity of our species to both adapt to and transform our conditions. It is in this context that the Global Extinction Awareness System (GEAS) offers its forecast of the likely extinction of humankind within the next quarter-century.

POPSRobots Detect Behavioral Cues to Follow Humans “As humans, we constantly incorporate other peoples' current actions as clues (cues) as to what they may do in the future,” Sanjay Joshi of the University of California, Davis, told PhysOrg.com. “For instance, we have a ‘sixth sense’ on the highway to know that a certain car will swerve into our lane soon, based on the driver's current driving patterns. Then, we may become more defensive in our own driving. In our work, we wanted to begin the process of allowing robots to use behavioral cues (of humans or other robots), to make the robot's mission more reliable and accurate. In social work environments populated by numerous people and robots, these types of cues should be abundant.” The researchers explained that behavioral cues that robots might use could include any action or signal that the leader exhibits that hints at a future action. These might be intended behaviors, such as pointing or waving. Other cues might be unconscious, such as behaviors that indicate stress or sadness,

POPSWhat Do Your Genes Say About You? The Future of Personal Genomics The company 23andMe announced its DNA testing service last month in San Diego. You might think such a comprehensive analysis would costs thousands, but the process is actually relatively affordable. For less than $1,000 customers are able to learn virtually everything science currently knows about their biological code. For those wary of needles, you’ll be comforted to know that the DNA is retrieved conveniently and painlessly from a home mail-in saliva test kit.

POPS"Do Humans Have 23 years to Go?" Play Superstruct and Find Out -Invent the Future! “The survival horizon identifies the point in time after which a threatened population is expected to experience a catastrophic collapse,” GEAS president Audrey Chen said. “It is the point from which it a species is unlikely to recover. By identifying a survival horizon of 2042, GEAS has given human civilization a definite deadline for making substantive changes to planet and practices.” According to Chen, the latest GEAS simulation harnessed over 70 petabytes of environmental, economic, and demographic data, and was cross-validated by ten different probabilistic models. The GEAS models revealed a potentially terminal combination of five so-called “super-threats”, which represent a collision of environmental, economic, and social risks.

POPSWill Our Future Brains Be Smaller? Why does the brain need these two decision-making areas? What benefit does the new cortex bring? After all, extra brain means extra weight and energy required to carry it around. Furthermore, is the older sub-cortical system now largely redundant? If so, could we expect it to atrophy in future humans so our brains become smaller? The results of their modelling showed that when the threat level is high, such as the risk of being attacked by a dangerous animal, it is very useful to have the fast-acting, if inaccurate, system. But when dealing with situations which don't occur very often, or complex scenarios with many conflicting cues such as social situations, the cortical system is of more use than the sub-cortical system.

POPSHarnessing Microbes To Meet Our Future Energy Needs "Microorganisms can provide just the services our society needs to move from fossil fuels to renewable biofuels," said Rittmann. "Only the microorganisms can pass all the tests, and we should take full advantage of the opportunities that microorganisms present."
