Grant aims to improve environmental education

A Virginia Tech professor is leading a study on STEM-based environmental education programs to determine how to promote positive learning outcomes for students. The research, funded by the National Science Foundation, will observe 500 single-day field trips and analyze their characteristics to identify factors linked to better outcomes.

Scientists reveal the neural basis of confirmation bias

Researchers at Virginia Tech and University College London discovered a key brain region that drives confirmation bias, where activity modulates decision-making and memory. The study found that people tend to favor information reinforcing their existing opinions over contradictory ones.

Chiton mollusk provides model for new armor design

Researchers developed a parametric 3D modeling methodology to mimic the geometry of individual scales from the chiton mollusk. The scale armor model provides dual protection-flexibility performance through converging inward upon one another when under force, offering varying amounts of flexibility.

'Sneezing' plants contribute to disease proliferation

Researchers discovered that wheat plants' sneezing off condensation can spread spore-borne diseases like wheat leaf rust, causing crop yield losses up to 20%. Condensation droplets can carry spores and jump high distances, potentially spreading disease across entire crops.

Breakthrough paves way for new Lyme disease treatment

Researchers have discovered a cellular component called peptidoglycan that contributes to Lyme arthritis, a debilitating condition. The presence of peptidoglycan in synovial fluid may explain why some people experience symptoms despite no obvious infection, and could lead to new treatments.

What causes battery electrode failure?

A study by Virginia Tech researchers reveals that lithium-ion battery electrode failure is caused by the heterogeneity of individual particles, leading to inefficiencies in charging. The team used a synchrotron X-ray method to produce results and identified problems with batteries today, including uneven charging rates.

Studying the evolution of oceans -- grant

Frank O. Aylward's three-year grant will focus on computational genomics to understand evolutionary trends in prokaryotes and their roles in biogeochemical processes. The research aims to predict how microbes might respond to climate change and ocean acidification.

Jumping drops get boost from gravity

Using superhydrophobic surfaces and vertical condensers, the team found that combining surface tension and gravity increases condenser efficiency. This method sheds moisture more efficiently than relying solely on jumping droplets or gravity, benefiting power plants and other heat exchange systems.

New 3-foot-tall relative of Tyrannosaurus rex

A new, smaller relative of the mighty Tyrannosaurus rex has been discovered by Virginia Tech paleontologist Sterling Nesbitt. The newly named Suskityrannus hazelae stood 3 feet tall and weighed between 45-90 pounds, with a diet likely consisting of small animals. The fossil dates back 92 million years to the Cretaceous Period.

Expanding truck safety outreach program

The Virginia Tech Transportation Institute is expanding its Sharing the Road program to educate high school students on safe driving practices around commercial vehicles. Through the program, researchers will visit 15 mid-Atlantic high schools and provide hands-on experience for thousands of teen drivers.

Studying reintroduction of bull trout with simulations

A team of researchers used a simulation to project the genetic and demographic outcomes of bull trout reintroduction in Washington State, focusing on connectivity and habitat availability. The study found that sufficient gene flow and unoccupied patches are key to maintaining genetic variation and persistence.

Codifying the universal language of honey bees

Virginia Tech researchers Margaret Couvillon and Roger Schürch have decoded the universal language of honey bees, allowing scientists to interpret the insects' sophisticated communications. By deciphering waggle dances, they hope to better understand pollinators' preferred forages and food sources.

Honey bee gut microbiome research -- NSF grant

Researchers from Virginia Tech and Eastern Washington University are collaborating on a $958,415 NSF grant to study the critical role of the honey bee gut microbiome in health and defense against parasites. The team aims to develop a network of genes from the parasite, microbiome, and host to determine their interactions with each other.
