Research identifies protein that signals flowering in squash plants

...ng and development programs, because it can aid in optimizing crop yields and other traits for local environmental conditions. Experimental evidence indicates that a flowering-inducing substance, known as florigen, is produced in the leaves of a plant under inducing conditions, and then is transported throug...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

...llowing them to grow as they would normally--while optimizing the conditions for viewing them by microscopy. This enables researchers to monitor the cells under a microscope for long time periods (in excess of four days), during which the cells may divide multiple times and cycle through nearly all cellular fun...

Faster, low cost sequencing technologies needed to drive era of personalized medicine

...be sequenced for every DNA probe, which means that optimizing the nanoprinting process is critical to the goal of a $1,000 genome, according to Zhang. The researchers' first goal is a proof of principal for their approach. They plan to synthesize a universal DNA nanoarray on a 100 micrometer by 100 micromet...

Discovery of the first resistance gene to rice yellow mottle virus

...useful yet susceptible to the virus with a view to optimizing their use. Standard genetic studies first found evidence that resistance was controlled by a single recessive gene. Subsequent genetic mapping identified a fragment of chromosome 4 containing the resistance gene. Data from rice genome sequencing ha...

Gene signature assesses breast cancer outcomes

... features of gene expression profiling studies for optimizing treatment selection for individual patients." The 70-gene signature will be prospectively tested in a larger study called MINDACT, a trial coordinated by the European Organization for Research and Treatment of Cancer. This trial will assess whether ...

Researchers develop technologies to devour food pathogens

...obial pathogens. The largest obstacle remaining is optimizing the system to dispense the appropriate amount of chlorine dioxide, Morgan said. Enough of the gas must be deployed to kill the pathogens, but too much can cause a decrease of quality in the product, such as browning of leafy greens. "If the product...

Protein folding: Building a strong foundation

...ated in proteins and appear to have co-evolved for optimizing both the folding rate and the stability of proteins." Wittung-Stafshede's group, which specializes in experimental studies related to protein folding, tested the model's predictions against experimental data gathered for several forms of the protei...

Better sludge through metagenomics

... phosphorus, and it will lead to major advances in optimizing and controlling the EBPR wastewater treatment process," McMahon said. "In particular, it makes possible further research into why some wastewater treatment plants occasionally fail. These failures often result in serious pollution of lakes, rivers, a...

DOE publishes research roadmap for developing cleaner fuels

...o break down cellulosic materials into sugars, and optimizing the fermentation process to convert sugars to ethanol. Cellulosic ethanol is derived from the fibrous, woody and generally inedible portions of plant matter (biomass). The focus of the research plan is to use advances in biotechnology -- first deve...

Gut microbes' partnership helps body extract energy from food, store it as fat

...prove our personal health, including, for example, optimizing the performance of our gut microbial communities?" ...

Wisconsin scientists grow two new stem cell lines in animal cell-free culture

...r using these cells therapeutically." "We've been optimizing (culture) media on the existing stem cell lines since 1998, but it has only been recently that there have been dramatic improvements," says James Thomson, the senior author of the new study and a UW-Madison professor of anatomy who seven years ago wa...

High resolution 'snapshots' detail dynamics of a cocaine antibody

...ecessary to explore new incremental approaches for optimizing the efficiency of such catalytic activity. Novel functional groups could be introduced into first generation antibody catalysts by multiple rounds of mutagenesis and selection to produce improvements. In essence, this would allow scientists to dramat...

USC, Rice to develop bacteria-powered fuel cells

...e are already in the business of understanding and optimizing the metal reduction capacity, it seemed a reasonable step to apply the same approaches to understanding current production. What is new here is the incorporation of colleagues in chemistry, geology, engineering, and evolutionary biology to optimize ...

University of Arizona plant scientists to unravel maize genome

... aim at increasing yield and nutritional value and optimizing the properties crucial for grain products such as flour, noodles and pasta. "Once the corn genome sequence is in our hands, these advances can happen much faster," Wing said. Corn is one of the most important economic crops in the United States, an...

Student scientists create living bacterial photographs

...ing Tabor and Aaron Chevalier, realized that after optimizing the pigments and agar growth media, these bacteria could be used to convert light images shined onto the bacteria into biochemical prints. To create the photographs, the Texas students used a unique light projector largely designed and built by Cheva...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

...ferent cell types rather than focusing on ways for optimizing this potential for a specific cell type. Further studies will be required to better understand if and how they may be useful in a clinical setting," Dr. Strom added. The researchers say their original motivation was, and still is, to identify cells ...

When it comes to cell entry, being average has its advantages

...he more rapidly they reproduce. "Cells are simply optimizing the system," Freund explained. "If a particle is too big, there may not be enough receptors to bind to the virus. If it is too small, it takes too much energy to bend the cell membrane as it engulfs the invader." When the team compared the implicati...
