An antioxidant, a type of compound that prevents certain types of damage to living cells, appears to allow some kinds of plants to thrive on metal-enriched soils that typically kill other plants, says a Purdue University scientist.
This finding, published in the current issue of The Plant Cell, provides an important new insight for the development of plants that could be used to help clean polluted sites. The work also answers a fundamental question for researchers studying how certain types of plants tolerate levels of metals in their tissues that are toxic to most other plants. "We were able to clearly establish for the first time that plants that create and accumulate high cellular levels of the antioxidant glutathione are much more nickel tolerant," said David Salt, associate professor of plant molecular physiology in Purdues horticulture department.
The term antioxidant generally refers to a broad class of compounds that protect cells from damage otherwise caused by exposure to certain highly reactive compounds. Understanding the mechanism behind nickel tolerance provides an important tool for researchers like Salt, whose goal is to develop plants that remove toxic metals from the environment in a process known as phytoremediation, or extract useful metals from soil, a process known as phytomining.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
