“Badass” new method uses a magnetised protein to activate brain cells rapidly, reversibly, and non-invasivelyMo Costandi@mocost
Researchers in the United States have developed a new method for controlling the brain circuits associated with complex animal behaviours, using genetic engineering to create a magnetised protein that activates specific groups of nerve cells from a distance.
Understanding how the brain generates behaviour is one of the ultimate goals of neuroscience – and one of its most difficult questions. In recent years, researchers have developed a number of methods that enable them to remotely control specified groups of neurons and to probe the workings of neuronal circuits.The most powerful of these is a method called optogenetics, which enables researchers to switch populations of related neurons on or off on a millisecond-by-millisecond timescale with pulses of laser light. Another recently developed method, called chemogenetics, uses engineered proteins that are activated by designer drugs and can be targeted to specific cell types.
Although powerful, both of these methods have drawbacks. Optogenetics is invasive, requiring insertion of optical fibres that deliver the light pulses into the brain and, furthermore, the extent to which the light penetrates the dense brain tissue is severely limited. Chemogenetic approaches overcome both of these limitations, but typically induce biochemical reactions that take several seconds to activate nerve cells.

More than 90% of all soybean, cotton and corn acreage in the United States is used to grow genetically modified crops. Other popular and FDA approved genetically modified food crops include sugar beets, alfalfa, canola, papaya, summer squash, apples that don’t brown and bruise-free potatoes.
However, if you have been led to believe that genetically modified foods were one of the main reasons why the world was enjoying food with less pesticide residues, you are being misled – the fact is, GMOs replaced one class of harmful pesticides with something more poisonous – neonicotinoids, dicamba, 2,4-D, DDT, glyphosate and its family of products including Round Up – and therefore ended up doing more harm than good.

Lest you are thinking Kiwis, “we’re not affected by this over here”, as Kiwis who read the mainstream media often do, think again. Our stock is fed GE food (report the Greens) so it’s in our meat. Our pastures are also sprayed liberally with glyphosate (which our stock eats) and we had trial GE corn grow here in ’99 left to harvest with a raised threshold on GE’s acceptable levels, many thanks to Helen Clarke (all kept from the public at the time). It’s coming by increments. And it’s not labeled of course and since much of the corn and soy products found in so much packaged food now (that companies decline to declare the origins of) a very high percentage of that is GM.
