Researchers awarded $1.5M to create stem cell predictive model

Stem cells are the building blocks of the body, according to Penn State researchers. Though similar to one another at their origins, stem cells take on unique characteristics as they mature, becoming specialized cells throughout the body — such as bone, muscle, ligament, tissue or other organ cells.

Friends matter: More sociable giraffes live longer

Adult female giraffes that group together with more of their peers live longer than less sociable individuals, according to a five-year study of giraffes in Tanzania.

Andrew Patterson receives Society of Toxicology Achievement Award

The Society of Toxicology has named Tombros Early Career Professor Andrew Patterson of Penn State as the recipient of its 2021 Achievement Award, recognizing his significant contributions to the field of toxicology within 15 years of obtaining the highest earned degree.

Rebuilding soil microbiomes in high-tunnel agricultural systems focus of study

The presence of high salt and nitrogen concentrations in high- tunnel soils may make it more challenging to rebuild a healthy soil microbiome following a soil-clearing event, according to microbial ecologists in Penn State’s College of Agricultural Sciences.

Unusual DNA folding increases the rates of mutations

DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome. New research by a team of Penn State scientists shows that the elevated mutation rate in these sequences plays a major role in determining regional variation in mutation rates across the genome.

The business of bees

The economic value of insect pollination services is much higher than previously thought in the U.S., new research finds.

Finding a solution to the mushroom phorid fly problem was critical because Pennsylvania leads the nation in mushroom production.

Vector-borne diseases shaped human history and reveal race disparities

Vector-borne diseases (VBDs), such as plague, malaria and yellow fever, have significantly shaped society and culture, according to an international team of researchers. In a study published in Ecology Letters on Jan. 27, the team used historical evidence interpreted through an ecological lens to illustrate how VBDs have influenced human history, with particular attention to how VBDs have reinforced and exacerbated racism.

Vaccines against 10 diseases prevented 37 million deaths in last 20 years

Vaccine programs in low- and middle-income countries have prevented 37 million deaths in the last 20 years – 36 million of which have been in children under age five. These are the findings, published Jan. 28 in The Lancet, of the most comprehensive study of the impact of vaccination programs ever undertaken.

Summer weather conditions influence winter survival of honey bees

Winter survival of honey bee colonies is strongly influenced by summer temperatures and precipitation in the prior year, according to Penn State researchers, who said their findings suggest that honey bees have a "goldilocks" preferred range of summer conditions outside of which their probability of surviving the winter falls.
