“Xiang-Dong Fu, PhD, has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it. But a single discovery has launched Fu into a completely new field: neuroscience.
For decades, Fu and his team at University of California San Diego School of Medicine studied a protein called PTB, which is well known for binding RNA and influencing which genes are turned “on” or “off” in a cell. To study the role of a protein like PTB, scientists often manipulate cells to reduce the amount of that protein, and then watch to see what happens.
Several years ago, a postdoctoral researcher working in Fu’s lab was taking that approach, using a technique called siRNA to silence the PTB gene in connective tissue cells known as fibroblasts. But it’s a tedious process that needs to be performed over and over. He got tired of it and convinced Fu they should use a different technique to create a stable cell line that’s permanently lacking PTB. At first, the postdoc complained about that too, because it made the cells grow so slowly.
But then he noticed something odd after a couple of weeks — there were very few fibroblasts left. Almost the whole dish was instead filled with neurons.
In this serendipitous way, the team discovered that inhibiting or deleting just a single gene, the gene that encodes PTB, transforms several types of mouse cells directly into neurons. “

Congress is attempting to subpoena the tax records of our current president, Donald Trump. Anyone receiving more than a simple paycheck knows how complex the IRS code can be – which was created by Congress. Finding fault will not be difficult when anyone who deals in multiple properties is examined.
But is this a good idea? Who is perfect in all things? Will future presidents face a requirement for perfection in their IRS tax returns? Will a potential good presidential candidate defer from running?
The Gig Harbor Times believes the both democrats and republicans will clobber any future president with IRS tax return attacks if congress is allowed to continue badgering the president about tax returns. Do we really need a future full of income examination attacks on future presidents? When will it stop?
