To see how microbial activity changes near and inside roots, the researchers chose crimson clover, or Trifolium incarnatum, as a test plant. It’s a legume commonly grown as a cover crop in the U.S. Northeast that forms root nodules with bacteria like the one shown here. Credit: Penn State. Creative Commons

Novel technique reveals insights into soil microbe alarm clock

New study yields clues about when dormant microscopic bacteria and fungi in soil ‘wake up’ and colonize roots, which influences plant growth and health.

New director expands Center for Biodevices scope for higher impact

Scott Medina, William and Wendy Korb Early Career Associate Professor of Biomedical Engineering, was recently named the director for the Center for Biodevices within the Huck Institutes for Life Sciences.

With a $450,000, three-year U.S. National Science Foundation grant and equivalent funding from the Binational Science Foundation in Israel, an international team of researchers co-led by Thomas Wood, biotechnology endowed chair and professor of chemical engineering at Penn State, will investigate the role E. coli plays in the gut and how it may affect intestinal inflammation.

Q&A: Bacteria research could be a gut-punch to inflammatory bowel disease

In this Q&A, Wood spoke about the significance of gut bacteria in IBD and how Penn State’s advanced organ-on-chip technologies — which are engineered devices and systems of tissues grown inside microfluidic chips that mimic human physiology — could lead to new diagnostic tools and treatments.

Salty soil, scrappy bugs and shared ideas drive graduate student’s research

Sahil Pawar says that tackling the world’s agricultural challenges is not a task for one person — it requires a collective effort. That grounded view shapes the early-career entomologist’s research, which examines how environmental stressors, such as soil salinity, drought and climate change, influence the interactions between crops and the pests that feed on them.

A new study involving about 850,000 adults across six continental ancestries, has identified 13 genes associated with obesity across ancestries. While eight of these genes had been found in previous studies, five were identified for the first time, having no previous links to obesity. The colors of the DNA helix in the image represent ancestral difference in genetic background around the world. The black figures represent people who do not carry gene mutations found to be associated with obesity while the red figures carry them. The fraction of red and black figures highlights the differences in genetic mutations across the world. Credit: Deepro Banerjee, Girirajan Laboratory / Penn State. Creative Commons

Genes associated with obesity shared across ancestries, researchers find

A new study from Penn State involving nearly 850,000 adults across six continental ancestries has identified 13 genes linked to obesity, including five never before connected to the condition. The findings provide new insight into how genetics influence obesity and related diseases such as Type 2 diabetes and heart failure.

Spotted lanternfly may use ‘toxic shield’ to fend off bird predators

Spotted lanternflies may season themselves to the distaste of potential bird predators, according to a new study led by entomologists in Penn State’s College of Agricultural Sciences.

Feral hogs, like this one pictured in a Louisiana swamp, were an animal mentioned in a new study that analyzed over half a million tweets to understand how the public talks about invasive species.

Small group of users drive invasive species awareness on social media

A new study co-authored by a scientist at Penn State analyzed over half a million tweets to understand how the public talks about invasive species — and which accounts are driving the conversation.
