A multidisciplinary cohort of UC San Diego scientists and students are attending the 2023 Conference of the Parties, or COP28, in Dubai, in the United Arab Emirates . Following a year in which many climate records have been broken, the United Nations (UN) climate conference is focused on limiting and preparing for future climate change.
A new mathematical model predicts that mammalian sperm cells have two distinct swimming modes. This prediction opens new questions about potential connections between sperm cells’ motor activity and their transitions to hyperactivation phases that may play an important role in fertilization. The finding is part of a larger effort to use math and fluid dynamics to describe how mammalian sperm move. The research is led by a team of engineers at the University of California San Diego. The new work was published in the journal Physical Review Fluids on 15 November, 2023.
Dr. Donna Strickland visited UC San Diego to share stories of her work as an optical physicist who helped created chirped pulse amplification, for which she received the Nobel Prize in 2018.
