Lifestyle can shape the composition of beneficial bacteria and other microorganisms within the mouth, according to a new study led by Penn State biologists. The international team revealed how the ...

A team led by Sarah Pfaff, postdoctoral scholar in biology, developed a method to isolate plant cells and reprogram them into other cell types, similar to the way stem cells differentiate into ...

The “RNA world” hypothesis proposes that the earliest life on Earth may have been based on RNA — a single-stranded molecule similar in many ways to DNA — like some modern viruses. This is because, ...

“The Biology and Ecology Student Research Showcase is a fantastic opportunity for graduate and undergraduate biologists and ecologists to come together and share their research and practice ...

David Radice, associate professor of physics and of astronomy and astrophysics, has been selected to receive a Sustainment Award from NASA, which provides support for the sustainable development of ...

UNIVERSITY PARK, Pa. — On Oct. 29, MIT astrophysicist and planetary scientist Sara Seager presented the joint Science Achievement Graduate Fellows-Russell Marker Lecture in Astronomy and Astrophysics, ...

A newly discovered protein naturally houses an unusual binding site that can differentiate between rare earth elements, and researchers at Penn State have made it even better. Rare earth elements are ...

All lectures will be held at the Mathematics Department (114 McAllister Building) at the Penn State University Park campus. This workshop first met at Penn State University in the spring of 1991. It ...

The conventional Hall effect occurs only in electrical conductors or semiconductors in the presence of a magnetic field. It ...

A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, for example, to ones used to ...

Newborn stars are surrounded by disks of gas and dust within which planets are born, known as protoplanetary disks. In the Orion Nebula, the brightest and most massive stars emit intense ultraviolet ...

Motivated by applications to water quality monitoring using fluorescence spectroscopy, this talk will develop a source apportionment model for high dimensional profiles of dissolved organic matter ...
