Q&A: How better climate data supports smarter environmental decisions

Q&A: How better climate data supports smarter environmental decisions Gaby Clark Scientific Editor Andrew Zinin Lead Editor Accurate measurements are the foundation of effective environmental management and decision-making. Through advanced monitoring networks and computer models, Ken Davis, professor of meteorology and atmospheric science in Penn State's College of Earth and Mineral Sciences, and his research group are helping scientists, communities, and policymakers better understand...

Climate change and wine grapes: Go, stay or change?

Climate change and wine grapes: Go, stay or change? Lisa Lock Scientific Editor Andrew Zinin Lead Editor On a hot afternoon in California wine country, the sun can do more than warm a vineyard. When temperatures climb above 100°F, grape clusters can heat to nearly 140° in direct sunlight.

Dogs uncover invasive pests that experts missed in real-world vineyard tests

Dogs uncover invasive pests that experts missed in real-world vineyard tests Sadie Harley Scientific Editor Robert Egan Associate Editor At a Maryland vineyard, Debi Persing guided her Boston terrier, Xephyr, slowly down a row of grapevines. Vineyard workers and scientists had already identified several invasive spotted lanternfly egg masses hidden among the vines. They believed they had found them all.

Why many fungicide-treated soybean seeds may boost harvests but not farm profits

Why many fungicide-treated soybean seeds may boost harvests but not farm profits Gaby Clark Scientific Editor Andrew Zinin Lead Editor Many soybean farmers use seeds treated with fungicides to ward off disease, but the profits from these increased yields might not offset the cost of the treatment in most cases, according to a study published in Scientific Reports by researchers at Penn State. The researchers analyzed how seed treatments affect yield and profitability in soybean farms in the...

Scientists map more than 200 years of nature's progress

Scientists map more than 200 years of nature's progress Sadie Harley Scientific Editor Andrew Zinin Lead Editor Armed with trail cameras, artificial intelligence, and a powerful national research network, scientists are revisiting Lewis and Clark's legendary journey to see how America's wildlife has changed over the past 200 years. The University of Missouri is among 55 institutions partnering with the Smithsonian's National Zoo and Conservation Biology Institute on the Lewis and Clark Trail...

Fast-moving droplets synthesize key drug compounds at room temperature, no catalysts needed

Fast-moving droplets synthesize key drug compounds at room temperature, no catalysts needed Lisa Lock Scientific Editor Robert Egan Associate Editor Chemical reactions are the backbone to nearly all biological processes, including those used to make new medicines. However, these reactions can often take considerable time and require harsh conditions or materials—potentially inhibiting the timely development of life-changing drugs. Purdue University researcher Graham Cooks and his team at...

Ancient lake cores reveal unprecedented 2012 Rwenzori fire and ecological shift

Ancient lake cores reveal unprecedented 2012 Rwenzori fire and ecological shift Andrew Zinin Lead Editor For the past several years, Penn State geoscientist Sarah Ivory and her students have been among a team of scientists scaling the East African Rwenzori Mountains, collecting sediment core samples from lakes formed at the end of the last ice age as glaciers began receding in the region some 12,000 years ago. Among those cores was a surprising revelation: A 2012 wildfire that ravaged 16...

Farmed oysters may boost New York's dwindling wild populations

Farmed oysters may boost New York's dwindling wild populations Lisa Lock Scientific Editor Andrew Zinin Lead Editor Farmed oysters are mixing with and potentially adding to populations of wild oysters—a once-abundant species in New York's estuaries and rivers that has declined drastically over the last century. A new study, published in the journal Molecular Ecology, offers genetic evidence and the first documented proof that farmed eastern oysters are adding to and breeding with wild...
