‘Scialog’ grant to study how rising ocean temperatures affect fish behavior

A wildlife behavioral ecologist at Penn State is part of a multi-institution team that received funding from Scialog: Neurobiology and Changing Ecosystems, a international three-year initiative that aims to spark new science exploring neurobiological responses to rapidly changing environments.

The findings challenge previous beliefs that scientists can make assumptions about bees’ nutritional needs based on what they choose to consume, according to the researchers. Credit: Neringa Normantaite/Unsplash. All Rights Reserved.

What a bumble bee chooses to eat may not match ideal diet

A new study led by researchers at Penn State suggests that what bumble bees choose to eat may not line up with their ideal nutritional needs.

Warmer spots within fields have more blooms and more bees

Climate can vary across large areas of land, but it also can vary within much smaller areas such as farms. A new study by researchers at Penn State examined whether these microclimates — the climate of a very small or restricted area — affect pollination by both wild and managed bees and resulting wild blueberry yields.

How a genetic tug-of-war decides the fate of a honey bee

Despite having identical genetic instructions, female honey bee larvae can develop into either long-lived reproductive queens or short-lived sterile workers who help rear their sisters rather than laying their own eggs. Now, an interdisciplinary team led by researchers at Penn State has uncovered the molecular mechanisms that control how the conflict between genes inherited from the father and the mother determine the larva’s fate.

New York City is heating up, and East Elmhurst is feeling it. With an Outdoor Heat Exposure Index (OHEI) of 3.8, this Queens neighborhood faces medium-high heat risk due to elevated surface temperatures, low tree canopy and limited cool roofs. East Elmhurst ranks above both the NYC and Queens averages in heat exposure. Credit: Travis Flohr. All Rights Reserved.

Urban heat portal aims to tackle rising temperatures, protect at-risk residents

As heat and associated risks intensify in cities around the world, a new tool developed by researchers in the College of Arts and Architecture’s Stuckeman School at Penn State and the Department of Urban Policy at Hunter College aims to shed light on how rising temperatures affect New York City’s neighborhoods — and what can be done to protect the most vulnerable communities.

The findings may have implications for policymakers hoping to make these conservation programs more impactful, according to the researchers. Credit: Jon Flobrant/Unsplash. All Rights Reserved.

Some water conservation programs may get more value by targeting rural farms

Conservation programs aimed at boosting environmentally friendly practices by incentivizing farmers may get more bang for their buck by targeting rural farms rather than more urban ones, according to a study led by researchers at Penn State.

Réka Albert, Evan Pugh University Professor and professor of physics and biology at Penn State, has been elected to the National Academy of Sciences. She pioneered network science, a method that involves studying systems as networks, where individual components — like people, proteins or genes — are represented as "nodes," and their interactions are depicted as "edges." This approach led to new ways to visualize and analyze the intricate web of connections in various systems.​ Credit: Michelle Bixby / Penn State. Creative Commons

Feeling salty? Increased salt stress reduces tomato pest activity

Increased soil salinity can reduce damage from prominent tomato pests such as the tomato fruitworm, according to researchers at Penn State. They published their findings in the Journal of Plant, Cell and Environment.
