CSSB’s Ellington part of $4M UT-Austin BRAIN initiative grant

By Marc Airhart

Researchers at The University of Texas at Austin will receive three grants totaling $4 million to develop techniques for imaging and manipulating the activity of neurons in the brain, research that will help scientists explore the mechanisms of addiction, obesity, fear and many other brain states and disorders. The funding, provided by the National Institutes of Health, is part of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative launched last year by President Barack Obama.

Raising the Tail: Jim Allison’s Pioneering Cancer Treatment

This excerpt is from an article by Jenny Blair, published May 2, 2014 in The Alcalde:

In 2004, two weeks before her wedding day, 22-year-old Sharon Belvin was diagnosed with advanced melanoma. The cancer had spread through her lungs, and after five months of chemotherapy, doctors found it had invaded her brain. Her odds weren’t good: at the time, 10-year survival rates for stage IV melanoma hovered around 10-15 percent.

Researchers Discover Why It’s So Hard to Grow an Extra Finger

The fact that most humans have five digits on each hand and foot is due in part to a complex developmental pathway called Hedgehog. If something goes wrong in this process during development, say a mutation in a critical gene that affects itsexpression, a person might be born with extra fingers or toes, a condition known as polydactyly. New research shows that for at least one part of the pathway, there is a sort of failsafe mechanism that seems to make it harder for mistakes to happen.
