Synthetic microbiome therapy suppresses bacterial infection without antibiotics

Precise, targeted treatment using limited strains of gut bacteria effectively protected against C. difficile infection, severe symptoms and recurrent infections in mice.

'Growing Impact' discusses environmental contaminants, human health

The latest episode of Growing Impact discusses how environmental contaminants affect human health, a research focus for Penn State professors Andrew Patterson and Costas Maranas.

The complex effects of pesticide exposure on bumble bee health

The effects of pesticide exposure on pollinator health may be more complicated than originally thought, according to a team of researchers in Penn State’s College of Agricultural Sciences who recently published an article on the topic in Biology Letters.

Penn State to establish Animal Diagnostic Lab-West

With $6 million in state funding, the new facility, to be located at Penn State Beaver, will enhance animal health and support for animal agriculture in western Pennsylvania.

The flavonoids that provide insecticide-like protection to some corn lines against corn earworm larvae also provide pigments to the plants that show up in the silks, husks and kernels. Pictured here are the lines used in the research.  Credit: Penn State. Creative Commons

Select corn lines contain compounds that sicken, kill major crop pest

The compounds, called flavonoids, have an insecticidal effect on corn earworm larvae.

New research lends insight into the regulatory control of gene expression in the deadliest of the malaria parasites, Plasmodium falciparum, and provides opportunities for the development of new therapeutic approaches against the disease. PfSnf2L, in red, is an essential malaria parasite protein for developing from the asexual ring to the sexual transmission stage — shown at top with the arrow illustrating the trajectory of various stages of sexual development. When the PfSnf2L enzyme is inhibited by the small molecule, NH125, in green, this leads to disordered DNA packaging. Changes in DNA packaging with active — the white line — and inactive PfSnf2L enzyme — the blue line — are depicted. When the DNA packaging is disrupted, the necessary information for parasite development can no longer be read out and the malaria parasites die thereby blocking transmission.

Disrupting parasite gene regulation reveals new malaria intervention strategy

Malaria's deadliest parasite relies on precise gene regulation to survive. A new multinational study, including Penn State scientists, reveals key insights into these control mechanisms.

Young adults may be more vulnerable to nicotine addiction than the middle aged

People in their late teens and early 20s may be more sensitive to nicotine and more susceptible to nicotine addiction than middle aged adults, according to a new study in mice from researchers in the Penn State Department of Biobehavioral Health.
