October 24, 2008 - Google Tech Talks June 16, 2008 ABSTRACT Explore the brain's amazing ability to change throughout a person's life. This phenomenon-called neuroplasticty-is the science behind brain fitness, and it has been called one of the most extraordinary scientific discoveries of the 20th century. PBS had recently aired this special, The Brain Fitness Program, which explains the brain's complexities in a way that both scientists and people with no scientific background can appreciate. This is opportunity to learn more about how our minds work-and to find out more about the latest in cutting-edge brain research, from the founder of Posit Science and creator of the Brain Fitness Program software, Dr. Michael Merzenich. Speaker: Dr. Michael Merzenich, Ph.D. Michael M. Merzenich, PhD: Chief Scientific Officer Dr. Merzenich leads the company's scientific team. For more than three decades, Dr. Merzenich has been a leading pioneer in brain plasticity research. He is the Francis A. Sooy Professor at the Keck Center for Integrative Neurosciences at UCSF. Dr. Merzenich is a member of the National Academy of Sciences. He is the recipient of numerous awards and prizes, including the Ipsen Prize, Zulch Prize of the Max Planck Institute, Thomas Alva Edison Patent Award and Purkinje Medal. Dr. Merzenich has published more than 200 articles, including many in leading peer-reviewed journals, such as Science and Nature. His work is also often covered in the popular press, including the New York Times, the Wall Street Journal, Time and Newsweek. He has appeared on Sixty Minutes II, CBS Evening News and Good Morning America. In the late 1980s, Dr. Merzenich was on the team that invented the cochlear implant, now distributed by market leader Advanced Bionics. In 1996, Dr. Merzenich was the founding CEO of Scientific Learning Corporation (Nasdaq: SCIL), which markets and distributes software that applies principles of brain plasticity to assist children with language

Engineers at Stevens Institute of Technology have developed a technique to optically modulate the frequency of a laser beam and create a signal that is disrupted significantly less by environmental factors, says Dr. Rainer Martini. The research provides for enhanced optical communications, allowing mobile units not tied to fiber optic cable to communicate in the range of 100 GHz and beyond, the equivalent of 100 gigabytes of data per second. Eventually, the team hopes to extend the reach into the terahertz spectrum. The frequency or amplitude modulation of middle infrared quantum cascade lasers has been limited by electronics, which are barely capable of accepting frequencies of up to 10 GHz by switching a signal on and off.  Marini and his team have developed a method to optically induce fast amplitude modulation in a quantum cascade laser to control the laser's intensity. Their amplitude modulation system employed a second laser to modulate the amplitude of the middle infrared laser, using light to control light. The current detector is only capable of detecting frequencies up to 10 GHz, but Dr. Martini is confident that a new detector will make the system capable of much higher frequencies. With an optical system that is stable enough, satellites may one day convert to laser technology, resulting in a more mobile military and super-sensitive scanners, as well as faster Internet for the masses, says Martini.

Source: New York Times - Apr 11, 2011 In their new book, Infinite Reality, Dr. Jim Blascovich and Dr. Jerry Bailenson insist that 3-D conferences with avatars are nigh because consumer technology has suddenly caught up with the work going on in virtual-reality laboratories in academia. These psychologists point to three developments in the past year: the Microsoft Kinect tracking system for the Xbox, the Nintendo 3DS gaming device, and the triumph on "Jeopardy!" of IBM's Watson computer.

Please join us this November as we honor Carl Sagan and celebrate the beauty and wonder of the cosmos he so eloquently described. Carl Sagan was a Professor of Astronomy and Space Science and Director of the Laboratory for Planetary Studies at Cornell University, but most of us know him as a Pulitzer Prize winning author and the creator of COSMOS. That Emmy and Peabody award-winning PBS television series transformed educational television when it first aired in 1980, but now, thirty years later, it's gone on to affect the hearts and minds of over a billion people in sixty countries. No other scientist has been able to reach and teach so many nonscientists in such a meaningful way, and that is why we celebrate Dr. Sagan, remember his work, and revel in the cosmos he helped us understand.

Dr. Mandelbrot, a maverick mathematician, developed an innovative theory to study uneven shapes and applied it to physics, biology and many other fields.

The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to double by mid-century and triple by the end of the century. Even in light of unprecedented conservation, the additional energy needed is simply not attainable from long discussed sources these include nuclear, biomass, wind, geothermal and hydroelectric. The global appetite for energy is simply too much. Petroleum-based fuel sources (i.e., coal, oil and gas) could be increased. However, deleterious consequences resulting from external drivers of economy, the environment, and global security dictate that this energy need be met by renewable and sustainable sources. The dramatic increase in global energy need is driven by 3 billion low-energy users in the non-legacy world and by 3 billion people yet to inhabit the planet over the next half century. The capture and storage of solar energy at the individual level personalized solar energy drives inextricably towards the heart of this energy challenge by addressing the triumvirate of secure, carbon neutral and plentiful energy. This talk will place the scale of the global energy issue in perspective and then discuss how personalized energy (especially for the non-legacy world) can provide a path to a solution to the global energy challenge. Daniel G. Nocera is the Henry Dreyfus Professor of Energy at the Massachusetts Institute of Technology, Director of the Solar Revolutions Project and Director of the Eni Solar Frontiers Center at MIT. His group pioneered studies of the basic mechanisms of energy conversion in biology and chemistry. He has recently accomplished a solar fuels process that captures many of the elements of photosynthesis outside of the leaf. This discovery sets the stage for a storage mechanism for the large scale, distributed, deployment of solar energy. He has b
