e-devices coming in the next 20 years

by

The just-released February issue of the Journal of the Society for Information Display contains the first-ever critical review of current and future prospects for electronic paper functions – in other words reviewing and critiquing the technologies that will bring us devices like

  • full-color, high-speed, low-power e-readers;
  • iPads that can be viewed in bright sunlight, or
  • e-readers and iPads so flexible that they can be rolled up and put in a pocket.

The University of Cincinnati’s Jason Heikenfeld, associate professor of electrical and computer engineering and an internationally recognized researcher in the field of electrofluidics, is the lead author on the paper titled “A Critical Review of the Present and Future Prospects for Electronic Paper.” Others contributing to the article are industry researcher Paul Drzaic of Drzaic Consulting Services; research scientist Jong-Souk (John) Yeo of Hewlett-Packard’s Imaging and Printing Group; and research scientist Tim Koch, who currently manages Hewlett-Packard’s effort to develop flexible electronics.

The full paper is available at the journal’s site.

This Year

  • Color e-readers will be out in the consumer market by mid year in 2011. However, cautions Heikenfeld, the color will be muted as compared to what consumers are accustomed to, say, on an iPad. Researchers will continue to work toward next-generation (brighter) color in e-Readers as well as high-speed functionality that will eventually allow for point-and-click web browsing and video on devices like the Kindle.

Already in use but expansive adoption and breakthoughs imminent:

The Internet Just Ran Out of Numbers

by

The MIT “Technology Review” has an interesting article all about IPv4 finally running out of numbers, and what to expect next now that this has happened. here are some highlights from it …

Every available Internet protocol address has now been spoken for—which could mean huge trouble down the line.
…
The problem is that the current system for IP addresses, IPv4, uses numeric addresses that are 32 bits long—giving a total of just over four billion potential numbers, which must have seemed like a lot when IPv4 was introduced in 1981. But there are now seven billion people on Earth, and more and more of them—and their devices—are going online all the time. Fortunately, engineers realized the limitations of IPv4 a long time ago and lined up a successor, called IPv6, in 1998.
…
For ISPs, it’s a straightforward business dilemma: the two addressing schemes are not directly compatible, which means it would take a significant investment to let IPv4 users connect to IPv6 services. And having relied on the same system for as long as 30 years, they may not feel the need to change.

$1 Million is yours … if you can prove that Homeopathy works

by

To win $1 Million all you need to do is to prove to the James Randi Educational Foundation that Homeopathy actually works. That sounds like easy money, because obviously it works … surely it must, it can’t be a con. Think about it now, almost all pharmacies sell Homeopath remedies, in fact the UK has … Read more

Exercise Improves Memory and Brain Health

by

That old book of fables, the bible claims, “Bodily exercise profiteth little”,  science has now yielded further information that clearly demonstrates this is simply not true at all. A new study shows that one year of moderate physical exercise can increase the size of the brain’s hippocampus in older adults, leading to an improvement in … Read more

Could the Net become self-aware?

by

The question, “Could the Net become self-aware?” is one that I would normally dismiss quite quickly. If your source for good science is simply ripping off the plot from Terminator, then god help us if you ever moved beyond that and watched the Matrix. The question has indeed come up (well of course it has, … Read more
