| Whenever charge flows, there will be magnetic fields. It's common
| for this to occur, because all known life uses ion channels in
| some way, and multicellular organisms do use electrical potential
| for internal signaling (such as nervous systems). Thus, the study
| of magnetic fields can be used to gain information about the
| state of an organism and scientists are now applying this to
| plants as well.

|
| The new-age aspects of this article reminds me of this test ...

|
| Also, apparently the author's the "Head of Publishing at Vice
| Media". Could explain why it wasn't cut during editing.

| Sorry all. Does this mean that I should be letting my toaster
| handle the difficult problems I encounter in my life? Up or down?
| Lighter or darker?
|
| Is it now potentially true that the old saying "dumber than a box
| of rocks" is actually a high compliment?
|
| Since I have a lot, too many actually, of fridge magnets picked
| up on various vacations over the years plastered to metallic
| objects around my workspace, am I surrounded by artificially
| super-intelligent placards that spend all their time waiting for
| a properly formed query before they excitedly initiate a life-
| changing brain dump of knowledge that I could gain from no other
| source?
|
| This article was funny. I am going to use this to poke fun at my
| vegan relatives when they attack my decision to continue enjoying
| bacon, steak, and tendies.

|
| Based solely on the name, which conjures images of the origin
| of the radiation that we propose to study and potentially to
| reduce, I propose that we should use this toaster:
