Findings that two mutated genes alter plant growth and development could result in improved plants and enhanced cancer treatments, according to Purdue University researchers.
This mutant plant is stouter and bushier than a normal plant because of an alteration in two genes related to human multidrug resistance genes. A Purdue University research team led by Angus Murphy is uncovering functions of these genes and the related proteins that could result in heartier plants and improved treatment for human cancers.

In a paper published in Thursdays (6/26) issue of Nature, the scientists report that these abnormal, or mutant plants are able to reorient themselves in response to light and gravity more rapidly than normal, or "wild type," plants. Apparently plants behave differently in accordance with how a growth hormone moves through them. Because the two genes affecting transport of the hormone are related to human genes that impact the effectiveness of chemotherapy drugs, controlling these genes may allow physicians to better determine the dosage of cancer drugs.
"We now know that if we can modify these genes, we can control the growth of the plant in very specific regions," said Angus Murphy, assistant professor of horticulture and senior author of the paper. "This means we might be able to change the shape of upper portions of a plant or develop a more robust root system."

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
