Does early-life cellular activity influence cancer and aging?

New research from Michael Lampson and Mia T. Levine in the School of Arts & Sciences offers insight into how telomeres—protective chromosomal caps linked to aging and cancer in mammals—are inherited. Their finding that telomeres become longer or shorter during early embryonic development opens new avenues for research.

A summer in the tick trenches

With the help of five Penn undergrads, biology professor Dustin Brisson’s research group collected 9,000 tick specimens this summer to understand how seasonal activity patterns of these arachnids affects human pathogens and what role a changing climate might play.

Centuries after discovery, red blood cells still hold surprises
Four microscopic views of red blood cells.

In these microscopic close-ups, samples of red blood cells aggregate from left to right, becoming more compact despite the absence of platelets, long thought essential to clotting.

Centuries after discovery, red blood cells still hold surprises

In a new collaborative study, researchers at Penn turned to mechanical engineering to understand how blood clots can compact, even without platelets.

Professor Philip Rea wins Jesse H. Neal Award for Scientific Journalism

Rea, professor of biology in Penn’s School of Arts & Sciences and Belldegrun Distinguished Director of the Vagelos Program in Life Sciences & Management has won the Jesse H. Neal Award for Best Technical/Scientific Content for his article “Gliflozins for Diabetes: From Bark to Bench to Bedside,” published in American Scientist.

Ants and naked mole-rats and societal roles
Leafcutter ants moving around a bright green leaf.

In eusocial superorganisms like leafcutter ant colonies, labor is divvied up according to body shape and size, but PIK Professor Shelley Berger and her team discovered that molecular signals can override that blueprint. Their findings reveal how simple neuropeptides can reprogram ant behavior, reshuffling roles in nature’s most disciplined workforce.

Ants and naked mole-rats and societal roles

PIK Professor Shelley Berger and colleagues explored the genetic basis of labor distribution in communal-dwelling species and discovered that pathways dating back hundreds of millions of years are conserved across animal kingdoms. Their findings offer fundamental insights into complex social behaviors.
