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."

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
