Gut bacteria variation among human social groups emerges by three months of age

Bacteria and other microorganisms that live within the human digestive tract — the gut microbiome — differ with parent-reported race and ethnicity as early as 3 months of age, according to a new study co-led by Penn State.

Bee populations at risk of one-two punch from heat waves, pathogen infection

Extreme heat waves affect pollinators and the pathogens that live on them, creating a mutual imbalance that could have major economic and public health consequences.

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.

Q&A: Carbon voyage

Penn State Associate Professor of Mechanical Engineering Brian Fronk and Professor of Mechanical Engineering Jacqueline O’Connor, have received a three-year, $2 million grant from the Office of Naval Research to develop a shipboard carbon-capture system for use with naval gas turbines.

Mussels inspire an eco-friendly way to extract critical rare earth elements

Rare earth elements play a key role in clean energy, vital to the production of lightweight, efficient batteries and essential components in wind turbines.

College of Ag Sciences scientist receives grant to study gut homeostasis, diet

Can plants evolved to resist infection help humans do the same?

Playing catch-up on weekends may not improve cardiovascular cost of sleep loss

Whether it’s work or play that prevents us from getting enough shut-eye during the week, assuming we can make up for it by sleeping in over the weekend is a mistake.

Influenza shows no seasonality in tropics, posing challenges for health care

In temperate climates, like North America and Europe, flu season starts in the fall, peaks in the winter and ends in the spring.

Microbe-stuffed soil crusts menaced by climate change

Using a novel method to detect microbial activity in biological soil crusts, or biocrusts, after they are wetted, a Penn State-led research team in a new study uncovered clues that will lead to a better understanding of the role microbes play in forming a living skin over many semi-arid ecosystems around the world. The tiny organisms — and the microbiomes they create — are threatened by climate change.

New, simple and accessible method creates potency-increasing structure in drugs

Chemical structures called cyclopropanes can increase the potency and fine-tune the properties of many drugs, but traditional methods to create this structure only work with certain molecules and require highly reactive — potentially explosive — ingredients.
