New USDA grant to support graduate reproductive microbiome training program

The USDA NIFA has awarded Penn State a five-year, $238,500 grant to establish a graduate training pipeline in reproductive microbiome research.

Gene integral to initiating, sustaining sperm cell development identified

With male infertility a mounting global concern impacting approximately 12% of men, a Penn State research team has discovered a gene that plays a key role in initiating and sustaining spermatogenesis. The finding may open a door for future therapies to boost sperm counts.

Newly identified protein function may reveal understanding of lifetime fertility

A protein in mouse ovaries regulates the formation of the ovarian follicle reserve, which comprises a mammal’s lifetime supply of egg cells and surrounding support cells, according to new study conducted by a U.S.-Canadian team.

Animal scientist receives USDA grant to study reproductive dysfunction in cattle

A Penn State animal scientist has received a $650,000 grant from the U.S. Department of Agriculture to lead a team conducting research on reproductive dysfunction in cattle.

Penn State dairy cattle geneticist finds mutant gene threatening Holstein calves

In the fall of 2020, when Chad Dechow got a call from veterinarians in New York describing a strange condition affecting Holstein calves on two farms under their care, he was unfamiliar with the condition that came to be known as calf recumbency.

Chronic inflammation may lead to low milk production in breastfeeding moms

Eighty percent of mothers breastfeed their newborns, but only 25% breastfeed exclusively for the six months recommended by United States Dietary Guidelines, according to the Centers for Disease Control and Prevention.

Physiology Graduate Student Wins Top Prize at Graduate Exhibition

Huck Graduate Student Advisory Committee President Isabel da Silva was given top honors in the Health & Life Sciences category of the 2021 Graduate School Exhibition

White-throated sparrows are among the best-studied North American songbirds. With a typical wingspan of 6 to 7 inches, it breeds primarily in northern boreal coniferous and mixed forests and, a short-distance migrant, winters mainly in the southeastern U.S. To make these migrations, the bird's body changes significantly.

Songbird-body changes that allow migration may have human health implications

Songbirds that pack on as much as 50 percent of their body weight before migrating and that sleep very little, exhibit altered immune system and tissue-repair function during the journey, which may hold implications for human health, according to Penn State researchers.

Troy Ott

Troy Ott to discuss "the improbable series of events that led to your birth"

At this month’s "Science on Tap" event, Huck Associate Director and professor of reproductive biology Troy Ott will discuss viviparity — the development of an embryo inside the body leading to the birth of a live offspring. Viviparity is thought to have evolved from egg-laying animals. Ott's talk will focus on one of the enigmas of live birth that relates to the mother’s immune system.

Zinc deficiency before conception disrupts fetal development

Female mice deprived of dietary zinc for a relatively short time before conception experienced fertility and pregnancy problems and had smaller, less-developed fetuses than mice that ingested zinc during the same times, according to Penn State researchers including Francisco Diaz and Thomas Neuberger.
