1 . Kariko worked in a few different research jobs before landing a junior position at the University of Pennsylvania. And for many years her career at the UPenn was fragile. She migrated from lab to lab, relying on one senior scientist after another to take her in. She never made more than $60,000 a year. She struggled to raise the funding essential for a scientific career and never had a stable position. Kariko said she endured being made fun of by university colleagues for her dogged pursuit. In 2013, she was kicked out from UPenn — forced to retire. She said in an interview that the university told her that she was unfit for her work. Yet the scientist’s commitment to her work did not falter. “When I was terminated (终止), I didn’t feel sorry for myself,” she said. “I have to focus all the energy on seeking out what’s next.”

2 . Glover and her colleagues tested their hypothesis in the lab. In their experiment, they found that bees felt confused sometimes when the petals were very iridescent and that bees had no problem finding the flowers with more nectar when the petals were not very iridescent. The team shared its new findings in the March 21 Current Biology.
