Roots Engage in Underground Chemical Warfare
In addition to providing physical support and taking in nutrients, plant roots secrete a wide variety of compounds that affect other nearby roots, as well as insects and microbes. But because it goes on unseen, bactericidal root activity has not been extensively investigated—until now. Using the model plant Arabidopsis thaliana, a relative of garden-variety cabbage, Jorge Vivanco and co-workers a...'Underground' tunnels discovered as means for communication between immune system cells
University of Pittsburgh researchers first to report function of tunneling nanotubules Immune system cells are connected to each other by an extensive network of tiny tunnels that, like a building's hidden pneumatic tube system, are used to shoot signals to distant cells. This surprising discovery, being reported by two University of Pittsburgh School of Medicine researchers in the Septem...Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood. Soil was almost literally a black box to scientists interested in carbon. Now researchers at the University of Warwick have been able to shed light in that black box by getting a particular class of insects to expos...Earth's core modeled in underground experiment
In an underground bunker that brushes up...Underground Water Contamination In Tripura
Officials have reported about the underground water contamination in Tripura due to naturally present arsenic, fuelling fears of serious health hazards. // Tripura Public Health Engineering (PHE) department chief engineer Sunil Kumar Bhowmik said a study conducted by a Lucknow-based agency revealed that underground water contains arsenic of not less that 0.05 mg. The study sai...Underground Air - Associated With - DNA Damages
According to a new doctoral thesis from Karolinska Institutet, our everyday environments are full of airborne// particles that are harmful to varying degrees when inhaled. Particularly damaging to our cellular DNA are the particles from the underground system in Stockholm, Sweden. "Luckily, most of them do not remain in the underground for any length of time," says scientist Hanna Karl...
