Secret of how plants regulate their vitamin C production revealed

13.3.2015   |   Press monitoring

A QUT scientist has helped unravel the way in which plants regulate their levels of vitamin C, the vitamin essential for preventing iron deficiency anemia and conditions such as scurvy. Professor Roger Hellens, working with Dr William Laing from New Zealand's Plant and Food Research, has discovered the mechanism plants use to regulate the levels...

Researchers put mouse gene in cattle to make them less susceptible to TB

11.3.2015   |   Press monitoring

A team of researchers working at Northwest A&F University in China has found that introducing a particular mouse gene into cattle can give them better protection against tuberculosis. TB infections in cattle costs growers in many countries millions of dollars every year, the current strategy for combating the disease is to separate those that are...

Bioengineers put human hearts on a chip to aid drug screening

9.3.2015   |   Press monitoring

When University of California, Berkeley, bioengineers say they are holding their hearts in the palms of their hands, they are not talking about emotional vulnerability. Instead, the research team led by bioengineering professor Kevin Healy is presenting a network of pulsating cardiac muscle cells housed in an inch-long silicone device that...

Protecting crops from radiation-contaminated soil

6.3.2015   |   Press monitoring

Almost four years after the accident at the Fukushima Daiichi Nuclear Power Plant in Japan, farmland remains contaminated with higher-than-natural levels of radiocesium in some regions of Japan, with cesium-134 and cesium-137 being the most troublesome because of the slow rate at which they decay. In a study published in Scientific Reports, a...

Plant protein structure database will help to uncover unknown functions of plant genes

4.3.2015   |   Press monitoring

Rigorous analysis of the structures of thousands of plant proteins by Tetsuya Sakurai and colleagues from the RIKEN Center for Sustainable Resource Science has led to the construction of a database that will help scientists identify the functions of more plant genes. Although the complete genomes have been sequenced for a number of plants and...

Gene may help reduce GM contamination

2.3.2015   |   Press monitoring

Genetically modified crops have long drawn fire from opponents worried about potential contamination of conventional crops and other plants. Now a plant gene discovered by University of Guelph scientists might help farmers reduce the risk of GM contamination and quell arguments against the use of transgenic food crops, says Sherif Sherif, lead...

Fighting the Colorado potato beetle with RNA interference

27.2.2015   |   Press monitoring

Colorado potato beetles are a dreaded pest of potatoes all over the world. Since they do not have natural enemies in most potato producing regions, farmers try to control them with pesticides. However, this strategy is often ineffective because the pest has developed resistances against nearly all insecticides. Now, scientists from the Max...

Tissue engineering: Scientists grow leg muscle from cells in a dish

25.2.2015   |   Press monitoring

A team of researchers from Italy, Israel and the United Kingdom has succeeded in generating mature, functional skeletal muscles in mice using a new approach for tissue engineering. The scientists grew a leg muscle starting from engineered cells cultured in a dish to produce a graft. The subsequent graft was implanted close to a normal,...

Fungal waste biomass could be used to harvest microalgae for fuels

23.2.2015   |   Press monitoring

Waste biomass from fungal fermentation processes could be used to bind to and harvest microalgae being used in other biotechnology applications. A*STAR researchers have successfully demonstrated this procedure with fungal mycelium—the main vegetative part of a fungus such as the tangled mass of underground fibers beneath sprouting...

3-D engineered bone marrow makes functioning platelets

20.2.2015   |   Press monitoring

A team led by researchers at Tufts University School of Engineering and the University of Pavia has reported development of the first three-dimensional tissue system that reproduces the complex structure and physiology of human bone marrow and successfully generates functional human platelets. Using a biomaterial matrix of porous silk, the new...
