Why wait? New initiative gets students into the lab early

In 2020, the College of Science will give hundreds of undergraduates the opportunity to contribute to real research projects the year that they step onto campus.


The role of lizard lungs in evolutionary biology

Savannah monitor lizards have a unique airflow pattern that is a hybrid of bird and mammal flow patterns.


Humans of the U: Quaid Harding

“Worldwide, honeybee populations are in serious decline. That’s a big problem for humans—one in every three bites of food that you take were pollinated directly or indirectly by a bee.”


Unique brain cells linked to OCD and anxiety

In a new study, U scientists discovered a new lineage of specialized brain cells, called Hoxb8-lineage microglia, and established a link between the lineage and OCD and anxiety in mice.


How trees affect the weather

New research led by U biologists finds that some plants and trees’ water use can make droughts more intense.


Sex, lice and videotape

Biologists drove the divergence of different-sized feather lice from a single population. In four years the evolved lice had trouble mating with each other, a sign of speciation and they caught it on tape.


Campus is abuzz with innovation

Celebrate Pollinator Week in the U’s new bee-friendly garden.


A bird’s surprising sound source

U researchers find birds use a different organ to sing than humans do—producing sound with very high efficiency.


Humans of the U: Hollie Morales

“I never fathomed that I’d become a widow at 34, left to raise my four children alone, the oldest 15, the baby 2. Medulloblastoma was supposed to be a pediatric brain tumor, so how could it put a 36-year-old man in the grave in just eight months? It felt like déjà vu. My daddy died from glioblastoma brain cancer when I was 20 …. But I’m not going to tell you a sob story. I started school at 35 determined to make a difference in the world of cancer and this fall, I’ll embark upon my next quest—a Ph.D. in oncological sciences studying brain cancer here at the U. If I am able to make a difference in just one life all the years of studying, sleepless nights and sacrificing a social life will be worth it.”
