Nita Bharti to deliver 2022 Darwin Day Lecture

Nita Bharti, Penn State assistant professor of biology, will deliver a virtual lecture titled “Adaptation for Survival: Humans and Their Pathogens” at 4 p.m. on Thursday, Feb. 10, as part of Penn State’s 2022 Darwin Day celebration. Advance registration is required for the event, which is open to the public.

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.

Researchers use satellites to monitor bat habitat and study virus spillover

Over the last year and a half, the word "remote" has come to dominate a large portion of our collective consciousness. We’ve had to work remotely, learn remotely, and even socialize remotely. But before the pandemic, because of the nature of their research, remote was already a part of the daily lexicon of some Penn State researchers.

COVID-19 case trajectories may be predicted by surveying communities

The public’s willingness to comply with Centers for Disease Control and Prevention (CDC) recommendations correlates with COVID-19 case projections in zip codes where those surveyed about their intended behaviors live, according to Penn State College of Medicine researchers.

David Hughes makes Newsweek’s inaugural list of 'America’s Greatest Disruptors'

David Hughes—professor of biology and entomology, Huck chair in global food security, and founder of PlantVillage—has been named to a list of leading "disruptors" as a "planet protector" by the magazine Newsweek.

Should I be worried about the new omicron coronavirus variant?

The omicron variant (B.1.1.529) of SARS-CoV-2, which has now been detected in the U.S., has been listed as a "variant of concern" by the World Health Organization, which has stated that the overall global risk related to the variant is "very high."

Distortion: Researchers discover new strategy for antibodies to disable viruses

It is widely understood that antibodies neutralize viruses by latching onto their surfaces and blocking them from infecting host cells. But new research reveals that this barrier method isn’t the only way that antibodies disable viruses. An international team of researchers led by Penn State has discovered that antibodies also distort viruses, thereby preventing them from properly attaching to and entering cells.

New technique better assesses exposure of a population to a virus

Accurately assessing the exposure of a population to a particular virus is difficult because the tools for doing so do not account for the fact that many viruses comprise multiple circulating strains, or the fact that people can be vaccinated or naturally immune, among other factors. Using influenza as a model, a team of researchers led by Penn State has developed a new technique that overcomes many of these roadblocks.

New tool weighs costs and benefits of managing evolution of pathogens and pests

Spend money now on antibiotic stewardship practices or save the money but run the risk of potentially deadly antibiotic-resistant bacteria emerging later? A new economic tool can help physicians, farmers and other people whose activities may influence the evolution of biological organisms, such as pathogens and insects, decide when they should invest in evolution management strategies.

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.
