good news for foreign science grads in america, maybe

Republicans in the House of Representatives are introducing a bill that would set aside 55,000 visas for students who’ve completed graduate studies in science, engineeing, math or technology majors. The bill won’t increase the total number of visas however and faces some Democratic opposition because of this fact. From the New York Times:

The largely partisan bill was introduced on Tuesday by Representative Lamar Smith of Texas, the Republican chairman of the House Judiciary Committee. It would allocate up to 55,000 visas, known as green cards, each year to graduates with master’s or doctoral degrees from American universities, by means of a trade-off. The bill would abolish a lottery run each year that distributes the same number of green cards randomly to applicants from countries that do not have large immigrant populations in the United States.

The nearly 50 other sponsors of Mr. Smith’s bill include only one Democrat — Representative Henry Cuellar of Texas. Mr. Smith and Representative Eric Cantor of Virginia, the majority leader, have said the House will vote on Thursday.

A partisan fight broke out over Mr. Smith’s approach, which would not increase the overall number of green cards issued annually. On Friday Representative Zoe Lofgren of California, a Democrat whose district is home to many technology companies, introduced a measure that would create 50,000 new green cards for advanced graduates in the so-called STEM fields: science, technology, engineering and mathematics. That bill would not reduce the visas available to the lottery.

light activated muscle

Scientists have been hard at work designing artificial muscle that gets activated when exposed to light:

Sakar and colleagues at MIT teamed up with scientists at the University of Pennsylvania to genetically engineer mouse muscle cells that twinge in response to light. The researchers loaded the cells with a light-activated protein, let the cells fuse into fibers, and mixed them with a special gel to form 3-D strips smaller than the width of a grain of rice. Then, they hit the strips with narrow beams of blue light.

Only the light-zapped fibers jumped; those in the dark stayed still. “I was hoping it would work, but the first time I saw it, it was amazing,” Sakar says. “I was very, very excited.”

Sakar and colleagues even got the muscle fibers to show off a bit of brawn. Tissue strips stretched between two tiny elastic posts pulled the structures together when scientists switched on the light.
