In brief: Certain age-related DNA mutations are less common in human eggs

A new Penn State-led study suggests that human eggs may have a built-in defense against age-related DNA mutations, a finding that could help researchers better understand reproductive aging and health.

If beekeepers use organic management practices over time, they even can produce 50% more honey than when following conventional management practices, according to the researchers. Credit: Simon Kadula/Unsplash. All Rights Reserved.

Organic beekeeping can be even more profitable than conventional methods

Organic beekeeping can support healthy and productive honey bee colonies, and a new study led by researchers in Penn State’s College of Agricultural Sciences found that adopting organic honey bee colony management is not only profitable, but in some cases, it can be even more profitable than conventional management.

Huck Institutes of the Life Sciences names 2025-26 seed grant recipients

The Huck Institutes of the Life Sciences at Penn State has selected eight research teams that span 12 departments across six colleges to receive 2025-26 seed grant funding.

When the sidechain bases guanine (G) and uracil (U) are paired in the 3D structure of a molecule of ribonucleic acid (RNA) the unusual pairing creates an unusual molecular conformation called a “wobble," pictured on the left. New research shows that non-covalent modifications to the bases can further alter the conformation creating a “shifted wobble," shown on the right. This conformational diversity could help explain RNAs function versatility, according to the researchers. Credit: Md Sharear Saon/Bevilacqua Lab / Penn State. Creative Commons

Unusual molecular conformation could help explain RNA’s versatility

Researchers at Penn State developed methods to identify and characterize modifications to ribonucleic acid, or RNA, structure that could alter the molecule’s function and serve as unique drug targets.

Connection among gut fungi, genetics and disease risk in humans identified

Novel genome-wide association study sheds light on the human genetic determinants of the fungal component of the human microbiome and their relation to chronic disease.

New research by Penn State scientists shows that migration of farming groups was the dominant factor in the spread of agriculture, while cultural adoption by hunter-gatherers only played a minimal role.

Ancient DNA reveals farming spread through migration, locals slow to adopt it

Using mathematical models, computer simulations, and ancient DNA analysis, an interdisciplinary team of scientists at Penn State was able to measure how migration and cultural adoption each contributed to the expansion of farming.

The team's research, conducted on mouse-ear cress — scientific name Arabidopsis thaliana, pictured — and fava beans, or Vicia faba, revealed that sugars, along with maleic acid, a chemical involved in energy production, act as crucial messengers that control how and when plants “breathe” and “eat."

Messenger signals that cue plants to ‘eat’ and ‘breathe’ revealed for first time

A new study by an international team of scientists led by Penn State researchers reveals for the first time the molecular messengers that control how and when plants “breathe” and “eat,” which could have implications for agriculture.

What traits matter when predicting disease emergence in new populations?

Traits of early virus spread help determine if a virus will ultimately persist in a new population, according to new research.
