Plants may induce 'leaky gut syndrome' -- permeability of the gut lining -- in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State. By improving our understanding of plant defenses, the findings could contribute to the development of new pest control methods.
One of the 21st century's greatest challenges is to develop diets that are both sustainable for the planet and good for our bodies. An IIASA-led study explored the major drivers of widespread shifts to sustainable diets using a newly developed computational model of population-wide behavioral dynamics.
Destructive free radicals -- known as reactive oxygen species -- are thought to degrade the cells of phytoplankton and other organisms. A new paper, however, suggests that these molecules actually play a beneficial role, upending some conventional wisdom.
This study (called a systematic review and meta-analysis) combined the results of nine studies and examined the association between adherence to plant-based eating habits and risk of type 2 diabetes in adults. The analysis included 307,099 adults with 23,544 cases of type 2 diabetes.
Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host's nutrients. A new study led by researchers at Penn State and Virginia Tech reveals that the parasitic plant dodder has stolen a large amount of genetic material from its hosts, including over 100 functional genes, through a process called horizontal gene transfer.
A predictive model combining information about plant physiology, real-time soil conditions and weather forecasts can help make more informed decisions about when and how much to irrigate. This could save 40 percent of the water consumed by more traditional methods, according to new Cornell University research.
The unrelenting deforestation of the Amazon region could lead to a dramatic increase to the risk of destructive wildfire outbreaks, research has shown.
Researchers have shown for the first time that cigarette butts reduce plant growth. Cigarette butts are the most common form of litter worldwide, with an estimated 4.5 trillion discarded annually.
University of Guelph researchers are beginning to understand why some alligators develop stronger hearts after enduring low oxygen during early development in the egg.
When tornadoes touch down, we brace for news of property damage, injuries, and loss of life, but the high-speed wind storms wreak environmental havoc, too. They can cut through massive swaths of forest, destroying trees and wildlife habitat, and opening up opportunities for invasive species to gain ground.
