Really disappointed to see that this year's NSF GRFP solicitation excludes second-year grad students (this late in the application cycle too!)
I'm a previous recipient and applied in my second year because I did rotations during my first year. This unfairly penalizes rotation students.

There are two fatal cases of H5N1 in cats in California. Both cats had been fed raw milk from the recalled lot in the ongoing outbreak associated with Raw Farms. The milk wasn’t tested. But an astute veterinarian tested the cats for flu based on clinical suspicion.
