Dr. Theodore Berger's research is currently focused primarily on the hippocampus, a neural system essential for learning and memory functions.
Theodore Berger leads a multi-disciplinary collaboration with Drs. Marmarelis, Song, Granacki, Heck, and Liu at the University of Southern California, Dr. Cheung at City University of Hong Kong, Drs. Hampson and Deadwyler at Wake Forest University, and Dr. Gerhardt at the University of Kentucky, that is developing a microchip-based neural prosthesis for the hippocampus, a region of the brain responsible for long-term memory. Damage to the hippocampus is frequently associated with epilepsy, stroke, and dementia (Alzheimer's disease), and is considered to underlie the memory deficits characteristic of these neurological conditions.
The essential goals of Dr. Berger's multi-laboratory effort include: (1) experimental study of neuron and neural network function during memory formation -- how does the hippocampus encode information?, (2) formulation of biologically realistic models of neural system dynamics -- can that encoding process be described mathematically to realize a predictive model of how the hippocampus responds to any event?, (3) microchip implementation of neural system models -- can the mathematical model be realized as a set of electronic circuits to achieve parallel processing, rapid computational speed, and miniaturization?, and (4) creation of conformal neuron-electrode interfaces -- can cytoarchitectonic-appropriate multi-electrode arrays be created to optimize bi-directional communication with the brain? By integrating solutions to these component problems, the team is realizing a biomimetic model of hippocampal nonlinear dynamics that can perform the same function as part of the hippocampus.
The World Science Festival is a production of the Science Festival Foundation, a 501(c)(3) non-profit organization headquartered in New York City. The Foundation’s mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.
The World Science Festival’s signature event is an annual celebration and exploration of science that launched in 2008. Hailed a “new cultural institution,” by the New York Times, the Festival has featured such luminaries as: Stephen Hawking, E.O. Wilson, Sir Paul Nurse, Harold Varmus, Daniel Dennett, Eric Lander, Steven Chu, Richard Leakey, Sylvia Earle, Yo-Yo Ma, Oliver Sacks, Mary-Claire King, Chuck Close, Philip Glass, Charlie Kaufman, Glenn Close, Anna Deavere Smith, Bobby McFerrin, Maggie Gyllenhaal, Liev Schreiber, John Lithgow, Bill T. Jones, Charlie Rose, John Hockenberry, Elizabeth Vargas and Walter Isaacson.
Throughout human evolution, multiple versions of humans co-existed. Could we be mid-upgrade now? At TEDxSummit, Juan Enriquez sweeps across time and space to bring us to the present moment -- and shows how technology is revealing evidence that suggests rapid evolution may be under way.
Since the 70s, the Magnetic North Pole has moved more than 1500 km at a rate of 10 kilometres a year. In the 1980s, this increased to 30 km a year. Today, the Pole travels 50, even 60 km - close to 150 metres a day.
Scientists don't quite know why its speed has increased these past 20 years. The magnetic pole is moving northwest of the geographic pole and may soon be across the Arctic Ocean in Siberia.
To find their bearings, sailors the world over must know the exact angle of difference between the two geographic and the magnetic north poles: the 'magnetic declination.'
The magnetic pole moves from the North to the South and vice versa every 250,000 years on average and does it very suddenly. Over 180 reversals have been recorded already.
As the intensity of the magnetic field tends to diminish, our planet becomes more susceptible to solar storms. In 100 years, the intensity has decreased by 15%."

In the future, a woman with a spinal cord injury could make a full recovery; a baby with a weak heart could pump his own blood. How close are we today to the bold promise of bionics—and could this technology be used to improve normal human functions, as well as to repair us? Join Bill Blakemore, John Donoghue, Jennifer French, Joseph J. Fins, and P. Hunter Peckham at "Better, Stronger, Faster," part of the Big Ideas Series, as they explore the unfolding future of embedded technology.

Dr. Martin Kohn, Chief Medical Scientist, Care Delivery Systems, IBM Research
Abstract: We have solid ideas about the flawed state of healthcare, the critical need for change and the future we want. Improving health outcomes while controlling costs and personalizing healthcare are among the objectives. It is clear that enabling the transformation of healthcare will require making better decisions. At the same time we are dealing with huge and expanding volumes of data. We will need tools to help us gather and analyze data to bring relevant information to decision makers so that it easier to obtain evidence-supported choices. Unstructured, text-like content is a large fraction of the data we rely on for decisions. Up until recently we have had limited ability to use unstructured material effectively. IBM's Watson, with its ability to understand the nature of a question being addressed and to read and understand huge volumes of literature, makes such material more approachable. However, making medicine more precise mandates the use of other forms of data, and population observational techniques. Predictive analytics, to identify people that need specific attention, and comparative analytics to elicit evidence from populations that can be applied to individuals, are part of the process. IBM has developed robust resources that provide such information.

3D printing will soon allow digital object storage and transportation, as well as personal manufacturing and very high levels of product customization. This video by Christopher Barnatt of ExplainingTheFuture.com illustrates 3D printing today and in the future.
With companies like Apple, Facebook and Twitter recording record numbers and dominating the online world, it’s easy to forget that these companies are still quite young and had very humble beginnings. Since there are so many great interviews and discussions out there, we rounded up a number of interviews featuring those responsible for starting up some of the biggest tech companies out there. Some are quite long so you won’t be sitting through all of these in one go, but all are well worth watching.
