Asian longhorned beetle larvae eat plant tissues that their parents cannot

Despite the buzz in recent years about other invasive insects that pose an even larger threat to agriculture and trees — such as the spotted lanternfly, the stink bug and the emerald ash borer — Penn State researchers have continued to study another damaging pest, the Asian longhorned beetle.

New tuberculosis tests pave way for cow vaccination programs

Skin tests that can distinguish between cattle that are infected with tuberculosis (TB) and those that have been vaccinated against the disease have been created by an international team of scientists.

Some green ash trees show some resistance to emerald ash borers

Genes in green ash trees that may confer some resistance to attacks by the emerald ash borer express themselves only once the tree detects the invasive beetle's feeding, according to Penn State researchers.

Sense of smell, pollution and neurological disease connection explored

A consensus is building that air pollution can cause neurological diseases such as Alzheimer's disease and Parkinson's disease, but how fine, sooty particles cause problems in the brain is still an unanswered question. Now a team of Penn State researchers, using mice, have found a possible way, but more research is still needed.

Researchers find genes that could help create more resilient chickens

An international team of scientists, led by Penn State researchers, have identified genes that may help farmers, especially ones in low- and middle-income countries, breed chickens that can resist one of the biggest disease threats facing poultry today.

NIH Grant Funds Research to Pinpoint Natural Selection’s Influence on Genomes

With a $1.7 million grant through the National Institutes of Health, researchers led by Michael DeGiorgio will begin to tease apart individual forces to understand how much influence natural selection has had on our evolutionary path.

A new study led by researchers at Penn State has identified the gene responsible for the color switch between the red and black color forms of the bumble bee, Bombus melanopygus. The black form is similar to other bees in the Pacific Coastal region while the red form is similar to other bees in the Rocky Mountain region. IMAGE: LI TIAN, PENN STATE

How The Bumble Bee Got Its Stripes

Researchers have discovered a gene that drives color differences within a species of bumble bees. This discovery helps to explain the highly diverse color patterns among bumble bee species as well as how mimicry — individuals in an area adopting similar color patterns — evolves.

Food Scientist Kovac Receives Young Investigator Award

Jasna Kovac, assistant professor of food science in Penn State’s College of Agricultural Sciences, recently was named recipient of the Institut Merieux Young Investigator Award in Antimicrobial Resistance from the International Association for Food Protection.
