From corals to humans, a shared trigger for sperm to get in motion
Coral sperm require a specific pH to move, according to research from the School of Arts & Sciences, which identifies a signaling pathway that is shared by organisms including humans. The results inform how corals may fare with climate change.
Before geoengineering, some fundamental chemistry
Research led by Joseph S. Francisco of the School of Arts & Sciences examines the chemistry of a proposal to curb climate change’s effects—creating a sunshade in the upper atmosphere made of sulfuric acid—and finds that there’s more work to do to successfully pull off such a feat.
In the brain’s cerebellum, a new target for suppressing hunger
A research team led by J. Nicholas Betley in the School of Arts & Sciences has identified an entirely new way the brain signals fullness after eating. The findings offer a novel target for therapies that could dramatically curb overeating.
A new class of CAR T cells targets previously untargetable cancer drivers
Focusing on neuroblastoma, researchers from the Perelman School of Medicine and Children’s Hospital of Philadelphia have harnessed the immune system to destroy tumors.
With more kids eligible for vaccines, is the pandemic in a new phase?
With the FDA authorization last week, 28 million more children are eligible to be vaccinated against COVID-19. Experts from the School of Nursing and Perelman School of Medicine share their thoughts about what to expect in the weeks and months to come.
Supporting Philadelphia newcomers and longtime residents through Palms Solutions
