VIRUSES: Why do we need them?

Professor and virologist Marilyn J. Roossinck discusses good viruses on TRT World's Roundtable.

The Mighty Microbiome

The term "microbiome" has become widely used in recent years as people devotedly devour kimchi, kefir, and kombucha in an attempt to improve their digestion, depression, and blood pressure. Indeed, we now know that the trillions of microbes--viruses, bacteria, and fungi--that live on our skin and in our guts, lungs, and reproductive organs, among other places, play critical roles in our well-being.

Pesticide seed coatings are widespread but underreported

Pesticide-coated seeds — such as neonicotinoids, many of which are highly toxic to both pest and beneficial insects — are increasingly used in the major field crops, but are underreported, in part, because farmers often do not know what pesticides are on their seeds, according to an international team of researchers. The lack of data may complicate efforts to evaluate the value of different pest management strategies, while also protecting human health and the environment.

What are viruses anyway, and why do they make us so sick? 5 questions answered

You may sometimes have felt like you “have come down with a virus,” meaning that you became sick from being exposed to something that could have been a virus. In fact, you have a virus – actually, many – all the time. Some viruses cause the common cold, and some are crucial to human survival. New viruses can also emerge, and they typically create illness in humans when they have very recently jumped from another species to humans. As world health leaders try to determine how to respond to the new coronavirus, virus expert Marilyn J. Roossinck answers a few questions.

Fire blight publication featured in American Society for Microbiology podcast

A publication from the lab of Timothy McNellis, associate professor in the Department of Plant Pathology and Environmental Microbiology, was recently featured on “This Week in Microbiology,” a podcast produced by the American Society for Microbiology.

Diseases and Wildlife

In the 6th episode of the Reach podcast, we discuss diseases in wildlife. We joined Dr. Kurt Vandegrift in the field to learn how research is conducted using ticks and mice, and how he is trying to prevent the next big epidemic. Next, we speak with Dr. Marilyn Roossinck about white-nose syndrome and it is endangering little brown bats.

Microbial Inoculants for Agricultural Soils – Potential and Challenges

Researchers from the Penn State Microbiome Manipulation Lab are interested in the effects of plant-associated microbiomes on crop productivity.

Grant funds citrus greening resistance research

Tim McNellis, an associate professor in Penn State’s College of Agricultural Sciences, received a $171,000 grant from the Citrus Research and Development Foundation to research citrus greening resistance.

NIFA awards grant for microbial stress tolerance research

The National Institute of Food and Agriculture (NIFA) recently awarded Kevin Hockett $453,000 to assist in research focusing on how microbes tolerate distinct stresses.

Researchers Receive $950,000 to Develop Pest Controls for Organic Mushrooms

Dr. David Beyer is principal investigator on grant to develop organic management options for three most challenging mushroom pests.

New High-Throughput Sequencing Technologies Uncover a World of Interacting Microorganisms

PPEM scientists are among those at the forefront of microbiome research.
