Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease.

Interspecific feeding — when an adult of one species feeds the young of another — is rare among songbirds, and scientists could only speculate on why it occurs, but now, Penn State researchers have new insight into this behavior.

The extraordinary ability of hummingbirds to perform complex escape maneuvers will be explored for its potential to enhance the field of robotics and micro aerial vehicles, thanks to a $923,483 grant from the Office of Naval Research.

With last year being the wettest year on record in Pennsylvania, and this year staring out wet again, 2019 was set up to be the mother of all fall foliage displays. 

Researchers at Western University have developed a new way to deliver the DNA-editing tool CRISPR-Cas9 into microorganisms in the lab, providing a way to efficiently launch a targeted attack on specific bacteria.

A mutant protein found in humans with colon cancer blocks a pathway that regulates proliferation and expansion of cells, increasing amounts of bacterial species associated with the development of colon cancer. 

Collagen is the most abundant protein in mammals, making up skin, bone, tendons and other soft tissues.

Insect-eating bats navigate effortlessly in the dark and dolphins and killer whales gobble up prey in murky waters thanks in part to specific changes in a set of 18 genes involved in the development of the cochlear ganglion — a group of nerves that transmit sound from the ear to the brain, according to a study by researchers at Stanford University.

The microbiome is a collection of trillions of bacteria that reside in and on our bodies.

Much less invasive than current dependence on examining cerebrospinal fluid.
