or rabbis, the first question is: Is it kosher? Certainly, there are many Jewish legal hurdles test-tube meat would have to clear before a definitive answer could be reached. A central point of debate is the origin of the cells, which some say would have to come from a kosher—that is, cloven-hoofed, cud-chewing—animal. “As a general principle, something derived from a nonkosher animal is not kosher,” says Rabbi Menachem Genack, head of the Orthodox Union’s Kosher Division.
Others, such as Rabbi Carl Feit, chair of the biology department at Yeshiva University, say cultured meat could still be kosher even if the donor animal isn’t. Feit points to the Jewish legal principle of nullification, which states that a trace amount of a forbidden substance can be fully absorbed into an acceptable one without rendering the second treif, or forbidden. If, for example, a piece of meat falls into a glass of milk, the milk is still considered kosher as long as the meat is not more than one-sixtieth of the mixture.
A primary application for many smartphone users is photography. Photo quality has improved a lot and most people aren't terribly demanding, but physics limits what a camera can do. Panasonic is exploring what a communication enabled camera can do with the Lumix CM1 - what if a smartphone was more along the line of a high end pocketable camera.
It is unlikely to have a huge market - for most people it is probably a bad idea. But something like this may be just the thing for those who find smartphone photography lacking and recognize the best camera is the one you are carrying.
We’ve known for some time that multi-tasking is bad for the quality of cognitive work, and is especially punishing of the kind of cognitive work we ask of college students.
This effect takes place over more than one time frame — even when multi-tasking doesn’t significantly degrade immediate performance, it can have negative long-term effects on “declarative memory”, the kind of focused recall that lets people characterize and use what they learned from earlier studying. (Multi-tasking thus makes the famous “learned it the day before the test, forgot it the day after” effect even more pernicious.)
People often start multi-tasking because they believe it will help them get more done. Those gains never materialize; instead, efficiency is degraded. However, it provides emotional gratification as a side-effect. (Multi-tasking moves the pleasure of procrastination inside the period of work.) This side-effect is enough to keep people committed to multi-tasking despite worsening the very thing they set out to improve.
On top of this, multi-tasking doesn’t even exercise task-switching as a skill. A study from Stanford reports that heavy multi-taskers are worse at choosing which task to focus on. (“They are suckers for irrelevancy”, as Cliff Nass, one of the researchers put it.) Multi-taskers often think they are like gym rats, bulking up their ability to juggle tasks, when in fact they are like alcoholics, degrading their abilities through over-consumption.
An engineering project that aims to address an area that has been largely ignored - making a better breast pump. There are many areas where progress stopped decades ago that aren't 'interesting enough' to attract the necessary innovation.
a pdf template to print and cut out. (you should measure one of the diagonials to verify your browser to printer isn't scaling). I found a sheet of quarter inch cardboard - close enough the the device thickness and made a quick mockup using the template.
My hands are large enough that I can semi-comfortably use the 5.5, but the 4.7 would be much more practical as a single handed device. The question for me is would I use it as a mini iPad mini and read books on it?
