A better estimate for tick numbers with ‘citizen science’ data
A better estimate for tick numbers with ‘citizen science’ data
A team led by School of Arts & Sciences biologists found a way to account for biases in data collected by members of the public, using it to create a comprehensive abundance map of the tick responsible for transmitting Lyme disease.
From corals to humans, a shared trigger for sperm to get in motion
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.

Common gene variants linked to sepsis and COVID-19 severity in African Americans
Two genetic risk variants that are carried by nearly 40% of Black individuals may exacerbate the severity of both sepsis and COVID-19. A Penn Medicine study identifies two potential pathways to reduce the health disparities driven by these gene mutations.

Need to break up with someone? Baboons have found a good way to do it, study finds
Robert Seyfarth of the School of Arts & Sciences spoke about how and why groups of primates “break up” and warned not to project that information onto human relationships. "You always find somebody who says, yeah, the baboons are showing us that you shouldn't have a despotic breakup and it's bad to just dump somebody and walk off," he said. "But I guess I'm not going to go into that territory."

The inner lives of cats: what our feline friends really think about hugs, happiness and humans
Carlo Siracusa of the School of Veterinary Medicine said cats are capable of bonding with people, contrary to claims that they’re merely using their owners for food and shelter. “Humans hug and kiss. Dogs become very excited and jump around. Cats don’t do anything like that. They are much more elegant,” he said. “They approach us. They bump their heads. Then they have some contact with us and walk away.”

The protein that keeps worker ants in line can also make them queen
Research by PIK Professor Shelly Berger and Roberto Bonasio of the Perelman School of Medicine found a protein in the brains of ants is responsible for regulating social behavior. “Kr-h1 is required to maintain the boundaries between social castes and to ensure that workers continue to work while gamergates continue to act like queens,” said Berger.

’Social’ mitochondria, whispering between cells, influence health
James Eberwine of the Perelman School of Medicine spoke about how mitochondria interact, communicate, and mutate. “If we understand how the mitochondria are acting together, and we learn how to manipulate it,” he said, “we’re going to gain so much more insight into biology.”
