Chinese Scientists Engineer the World's Smartest Rat
In a development that gives Acme Labs and NIMH a run for their money, scientists in Georgia and China have collaborated to create the world's smartest rat. The genetically engineered rat, Hobbie-J, over-expresses a gene that regulates neuron communication, greatly enhancing the rat's ability to navigate mazes and remember toys. This new rat confirms a decade-old experiment run by the same scientists that increased the intelligence of a mouse by changing the same gene. The gene, called NR2B, regulates the pores on neurons. By increasing pore activity, the scientists effectively increased processing speed of the rat's brain. The researchers hope this discovery will lead to drugs that target NR2B specifically. Diseases like Alzheimer's affect NR2B expression, so a drug that causes the gene to over-express could counteract the affects of the disease. Similarly, a regular person could conceivably take the drug to become even smarter....
