I learned how to read well because I was doing it all the time. A Goosebumps book and an encyclopedia volume hated to see me coming. I dont even know how you develop proper reading skills if you only read books at school.

Announcing such a major change to NSF GRFP this late in the cycle is incredibly cruel. 2nd yr students (mine included) have been working so hard on their proposals despite ongoing uncertainty. They are driven and passionate about being outstanding scientists and helping those coming up behind them.

This means individuals in the following statuses at the time of application are eligible:

Undergraduate in the final (senior) year of a bachelor’s degree program
Bachelor’s degree-holder with NO enrollment in a graduate degree program (non-degree graduate coursework allowed)
Individual enrolled in a joint bachelor’s-master’s degree program with at least three undergraduate years completed
First-year graduate student in their first graduate degree program with less than one academic year completed in the degree program (according to institution’s academic calendar)
Individuals enrolled in joint bachelor’s-master’s degree programs are considered graduate students. For GRFP, joint bachelor’s-master’s degrees are defined as degrees concurrently pursued and awarded.
Not be a current NSF employee.

Applications that do not meet eligibility requirements will be returned without review as being ineligible for a fellowship.

Happy to share the my lab's latest preprint, where we investigated sensorimotor circuit formation in the developing spinal cord. We show that proprioceptive axons target motor neurons in neighboring spinal segments to give rise to intersegmental reflex responses.

One of the funnier things about the Yale prof who is advocating Niemollering the humanities is that his nirvana already exists. They are called Research Institutes. Why doesn’t he just change jobs to one of those and stop telling everyone else what to do?
