A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a Penn State College of Agricultural Sciences reproductive physiologist. Research involved manipulating a protein called STAT3, which is active in tissues throughout the body and is essential for life, that signals stem cells to decide whether to differentiate into a specialized type of cell or self-renew and remain stem cells.

A dairy nutritionist in Penn State's College of Agricultural Sciences is conducting genetic research with mice to determine if cows can be influenced by diet to produce milk with a higher fat content. You read that right. "On the surface, it may seem like a strange concept, experimenting with mice to learn things about cows," said Kevin Harvatine, assistant professor of nutritional physiology. "But the lactating dairy cow is not amenable to transgenic approaches. The mouse offers the greatest opportunity for genomic manipulation, and we have successfully developed a lactating mouse model to investigate milk-fat depression in dairy cows."

Memorial Day marked the unofficial kick-off of barbecue season, and a meat specialist in Penn State State's College of Agricultural Sciences said the watchword for 2010 is variety. Chris Raines, assistant professor of meat science and technology in the college's dairy and animal science department, said while trends run the gamut from luxury grills to the medical benefits of marinades, three significant developments can be identified.

Some say there's nothing new under the sun, but researchers in Penn State's College of Agricultural Sciences are finding new ways to squeeze more out of it every year by extending Pennsylvania's growing season. They're also squeezing more out of this geographic growing zone by producing exotic fruits and vegetables normally found in more temperate ...

A recently completed, four-year Penn State study of male wild turkey harvest and survival rates in three northeastern states shows that game managers and hunters have a choice to make. Do they want more spring hunting opportunity at the risk of fewer adult gobblers available for harvest?
