E Ink Android Phone Lasts a Week, Weighs Next to Nothing
Who would want a smartphone with a grayscale E Ink screen?? Anyone who want days of? battery life, superior outdoor readability and low cost should be interested in using the technology in a phone. At Mobile World Congress?this week, we got our hands on a prototype Android smartphone with an e-Ink screen and were blown away by just how light it was about how sharp text looked on its screen and how long it could last.
Not keen on giving up your full-color, full HD display on your phone? E Ink technology should be coming soon to back covers for phones, supplying info at a glance without draining your battery.
The device we used has no official name, because it?s one of only a handful of prototypes made by eInk, the company behind the grayscale screens that power so many popular devices like the Kindle and Nook. Our demo came courtesy of Nicholas Charbonnier, the proprietor of ARMdevices.net who has reported extensively about the evolution of? E Ink technology. The device is designed to last at least a week on a charge and cost cost as little as 150 euros unsubsidized, he said.
Charbonnier told us that E Ink ?is working with hardware partners not only to bring full-fledged E Ink smartphones to market, but also to develop E Ink back panels for popular phones with removable backs. The end products, which could cost as little as $50, would be replace users? existing battery covers with ones that had E Ink screens.
These E Ink accessories would use Bluetooth to communicate to the phone and an app would allow users to put their favorite content on the back of the phone where it could be viewed even when the phone is asleep. Because E Ink screens don?t use any power when not actively changing pictures, these second screens would help increase battery life by helping you avoid activating the front display as often.
The Russian Yota Phone, which we saw at CES, will come with an E Ink screen on its backside when it launches later this year. These upgrade panels would allow users of popular phones to get the same functionality. However, no partnerships have been announced as of yet for either a back panel E Ink replacement or standalone E Ink phone.
Perhaps because it can use a smaller battery or because it has an older ARM processor ? Charbonnier said it has a Qualcomm A5 chip ? the reference design weighed a mere 80 grams and felt as light as paper in our hand.?
The device was running a very stripped down, ancient version of Android with a home screen that had a set of tiles for Messages, Phone, e-Reader, Contacts, Applications and Settings. The applications menu had just a handful of apps, including a voice recorder, web browser and a Chinese app. The contacts list, settings and dialer were all standard Android 2.3 apps. The e-Reader had a list of Chinese-language books and, when we opened them, text was sharp.
Unfortunately, it was too dark out at the time of our hands-on to do a direct sunlight test, but Charbonnier captured images of the device outdoors for an article on the E Ink phone and they show a Samsung phone with a screen that?s completely unreadable in the sun right next to the very-sharp E Ink phone. That said,we noticed a lot of bugs in the way the screen drew and redrew it self; there were often artifacts on the screen, which Charbonnier cleared away by shaking the device.
Navigating between menus was painfully slow, and though the device supports multitouch gestures such as pinch-to-zoom, it wasn?t always responsive. There was also significant lag when redrawing the screen, which is always a problem on E Ink screens but was particularly sluggish on this device. That said, it?s important to note this is very much a reference design and proof of concept. When final E Ink phones come out, Charbonnier says they will undoubtedly have an Android skin that uses fewer animations and non-scrolling menus so that the slow draw times are not a problem.
The low power, sharp and images, light weight and low price of dedicated E Ink phones make them particularly compelling for developing markets where cost is important and power is scarce. However, having a second E Ink screen like the Yota Phone is truly compelling in any environment. We can?t wait to see how this initiative turns out.

Reducing numbers of one carnivore species indirectly leads to extinction of others
Reducing numbers of one carnivore species indirectly leads to extinction of others
Friday, March 1, 2013Previous studies have shown that carnivores can have indirect positive effects on each other, which means that when one species is lost, others could soon follow. A team from the University of Exeter and the University of Bern has now found that reducing the numbers of one species of carnivore can lead to the extinction of others.
Published onlinein the journal Ecology Letters, the study shows that simply reducing the population size of one carnivore can indirectly cause another similar species to become extinct. The research shows that changes in population size, as well as extinction, can create ripple effects across sensitive food webs with far-reaching consequences for many other animals.
The research shows that species could suffer just as much from harm to another species as from being under direct threat themselves. This adds weight to growing evidence that a 'single species' approach to conservation, for example in fisheries management, is misguided. Instead the focus needs to be holistic, encompassing species across an entire ecosystem.
The researchers assembled experimental ecosystems with three species of parasitic wasps, along with the three types of aphids on which each wasp exclusively feeds. They set up four sets of tanks each containing the three aphid and three wasp species and allowed the populations to establish for eight weeks. Over the next 14 weeks (seven insect generations) the researchers removed a proportion of the wasps from three of the sets of tanks every day - one species from each set. The fourth set had no wasps removed.
The team found that the partial removal of one wasp species led indirectly to the extinction of other wasp species. In the absence of one wasp species, the aphid it preyed upon grew in numbers. All three species of aphid feed on the same plant so increased competition for food led to changes in sizes of the aphid populations. However no aphid species went extinct and so the indirect extinctions of the wasps were not the result of extinction of their prey. Rather, it is likely that the wasps that went extinct had difficulty searching for suitable prey among large numbers of unsuitable ones.
Lead researcher Dr Frank van Veen of the University of Exeter's Centre for Ecology and Conservation said: "We have shown that the complex ripple effect of a change in population size across food webs is more sensitive than previously thought and that a reduction in the numbers of one carnivore can lead to the extinction of another carnivore species. We also found evidence that the initial indirect extinction can itself trigger further ones, potentially leading to a cascade of extinctions, like dominoes toppling over."
"The insect system is handy for experimentation but the same principles apply to any ecosystem, from mammals in the Serengeti to the fish in our seas. It clearly shows that we should have an ecosystem-based approach to conservation and to the management of fish stocks and other natural resources."
The research team has recently been awarded a ?470K grant by the Natural Environment Research Council (NERC) to extend this research at a larger scale.

Reading Your Trust (and Estate Plan) | The KC Estate Planner
Read your trust.?Yes, I know, reading a will, trust, or almost anything written by a lawyer (except John Grisham or Scott Turow) sounds as appealing as doing your taxes, having a root canal, getting caught in a blizzard, or spending the night in an airport. And understanding ?legalese? is even more daunting. Let?s face it: most lawyers don?t write well,?and when they do write, they level forests, producing 50 page ?briefs?and minor novellas by the hour. Lawyers speak legalese and often leave a trail of misplaced participles, dangling modifiers, and bizarre archaic phrases (e.g. ?hereafter,? ?heretofore,? ?said party of the first part,? ?such party of the second party,? ?inter alia,? ?res ipsa loquitor,? ?stare decisis et non quieta movera,? ?cy pres,? ?stipulated,? ??subsequent,? ?give, bequeath, and devise,? and ?situate?). Most people don?t read the small print, we all just want to get it done (and leave the details to the professionals). People hire lawyers to apply their wishes and desires for the future to their family?s legal landscape: clients tell lawyers??we want X,? now figure out how to do it. And lawyers are the professionals who what you need in a will, trust, living will, powers of attorney, and who can answer your tax issues, and other vital questions.
If you?d like to work with a lawyer who speaks and writes in plain English and can help you decipher the legalese of your trust and other estate planning documents, give me a call (913-707-9220) or email me (steve@johnsonlawkc.com) for a convenient free consult with my firm, Johnson Law KC LLC. We practice law differently.

Strains of antibiotic-resistant 'Staph' bacteria show seasonal preference; Children at higher risk in summer

Strains of potentially deadly, antibiotic-resistant Staphylococcus aureus bacteria show seasonal infection preferences, putting children at greater risk in summer and seniors at greater risk in winter, according to results of a new nationwide study led by a Johns Hopkins researcher.
It's unclear why these seasonal and age preferences for infection with methicillin-resistant Staph aureus (MRSA) occur, says Eili Klein, Ph.D., lead author on the study and a researcher at the Johns Hopkins Center for Advanced Modeling in the Social, Behavioral and Health Sciences.
But he says that increased use of antibiotics in the winter may be one of the reasons. The winter strain that infects seniors at a greater rate is generally acquired in the hospital and resistant to more antibiotics. On the other hand, the summer strain of MRSA, which is seen with growing frequency in children, is largely a community-transmitted strain that is resistant to fewer antibiotics.
"Overprescribing antibiotics is not harmless," Klein notes. "Inappropriate use of these drugs to treat influenza and other respiratory infections is driving resistance throughout the community, increasing the probability that children will contract untreatable infections."
In fact, the study found that while MRSA strains exhibit a seasonal pattern, overall MRSA infections have not decreased over the last five years, despite efforts to control their spread.
A report on the study, which used sophisticated statistical models to analyze national data for 2005-2009, appears today in the online issue of the American Journal of Epidemiology.
As the researchers report, hospitalizations from infections tied to MRSA doubled in the United States between 1999 and 2005. The ballooning infection numbers were propelled by MRSA acquired in community settings, not hospital or other health care settings, as had been the case prior to 1999.
Specifically, the study found that a strain of MRSA typically seen in community settings is more likely to cause infection during the summer months, peaking around July/August. The authors' data analysis showed children were most at risk of becoming infected with this strain, typically from a skin or soft tissue wound or ailment.
In fact, in examining data for one year 2008 the research team found that 74 percent of those under the age of 20 who developed an infection with MRSA had a community-associated MRSA infection.
Meanwhile, the health care-associated MRSA strain, which is typically seen in hospitals, nursing homes and other health care settings, was found to be most prevalent in the winter months, peaking in February/March. Patients aged 65 or older are more likely to acquire a MRSA infection from this strain.
"Our analysis ... shows significant seasonality of MRSA infections and the rate at which they affect different age groups," write the authors of the report titled "The changing epidemiology of methicillin-resistant Staphylococcus aureus in the United States: A national observational study."
Klein said additional research on seasonal patterns of MRSA infections and drug resistance may help with developing new treatment guidelines, prescription practices and infection control programs.
