Omicron genetics and early transmission patterns are characterized in new study

The Omicron variant of SARS-CoV-2 diverged from previous SARS-CoV-2 variants as a result of adaptive evolution, in which beneficial mutations are passed on to future generations through natural selection, rather than through recombination between previous variants, according to a large international team of researchers. The study, which published recently in Nature, is the first to describe the genomic profile of Omicron and explore the origins of the variant.

Penn State biologists explore the secrets of the warbler genome

Looking through binoculars at the trees in their backyards during the pandemic, many brand-new birders may have been surprised by the diversity of visitors stopping by — finches, jays and warblers in an astounding array of yellows, blues and reds.

Okafor receives 2021 National Science Foundation CAREER Award

C. Denise Okafor, assistant professor of biochemistry and molecular biology, has been honored with a Faculty Early Career Development award from the U.S. National Science Foundation. The award is the NSF’s most prestigious honor in support of early-career faculty members who have the potential to serve as academic role models.

Nanoscale ‘computer’ controls function of protein, influences cell behavior

The creation of nanoscale computers for use in precision health care has long been a dream of many scientists and health care providers. Now, for the first time, researchers at Penn State have produced a nanocomputing agent that can control the function of a particular protein that is involved in cell movement and cancer metastasis.

Scientists uncover the genetic pathway that colors bumble bee stripes

While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors is because evolution can influence multiple bee species to share similar color patterns in specific geographic regions, which scientists call mimicry.

New way to image whole organisms in 3D brings key skin color pigment into focus

To understand the biological underpinnings of skin and hair pigmentation and related diseases such as albinism or melanoma, scientists and doctors need quantitative, three-dimensional information about the architecture, content and location of pigment cells. Penn State College of Medicine researchers have developed a new technique that allows scientists to visualize every cell containing melanin pigment in 3D, in whole zebrafish.

Vasant Honavar named Huck Chair in Biomedical Data Sciences and AI

Vasant Honavar, professor in the College of Information Sciences and Technology, has been named the Dorothy Foehr Huck and J. Lloyd Huck Chair in Biomedical Data Sciences and Artificial Intelligence by the University’s Huck Institutes of the Life Sciences.

BG student named semifinalist for genetics research award

The American Society of Human Genetics (ASHG) has selected Chen Wang, a graduate student from Penn State’s doctoral program in bioinformatics and genomics, as a predoctoral semifinalist for the 2021 Charles J. Epstein Trainee Awards for Excellence in Human Genetics Research.

Eberly’s 2022 Lab Bench to Commercialization grant recipients announced

The Eberly College of Science has chosen faculty members Joyce Jose and Sally Mackenzie to receive its 2022 Lab Bench to Commercialization grants. This competitive program provides funding for researchers in the college, enabling them to enhance the commercial potential of ongoing Penn State research and prepare them to translate their Penn State-owned intellectual property to the marketplace.

New tool reveals genetic influence of some sex-biased diseases, including lupus

Many human diseases can differ between males and females in their prevalence, manifestation, severity or age of onset. Examples include Lupus, where more than 80% of patients are females; Alzheimer’s disease, where females have higher incidence and tend to suffer quicker cognitive decline; and COVID-19 infections that are frequently more severe in males.
