A new plant-bacterial symbiotic mechanism promising for crop applications

...nal model have their own photosynthetic pathway, a unique property in the rhizobia (2). This special character confers on it the exceptional, rare ability to form nodules on the stems of its host-plant. The plant thus acquires the possibility of fixing much higher quantities of nitrogen than those usually m...

Envisat captures first image of Sargassum from space

...tarctic super blooms. It really gives us a new and unique view of the Earth." Gower and King are now combining data from MERIS with a sophisticated processing algorithm and powerful Grid computing to broaden this new view. The basic principle behind Grid computing is that anything one computer can do, a...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...tes in different geographic regions have developed unique patterns of mutations in the three genes mentioned above. Now, researchers can tell where a drug resistant parasite comes from depending on the varied mutations in the three different resistance genes, Roepe said. "There are patterns of mutations in ...

Pesticides choke pathway for nature to produce nitrogen for crops

...her the plants or bacteria, Fox said, "but PCP was unique in that it inhibited both seed germination and nitrogen fixation." More than 20 commonly used agricultural chemicals shared the same mechanism of action as PCP, but with varying amounts of signal disruption. Fox, McLachlan and colleagues, in thei...

Brain holds clues to bipolar disorder

...nderlie emotional processing and cognitive control unique to the bipolar brain. Such abnormalities are valuable biomarkers for the illness and have the potential to help clinicians diagnose bipolar disorder earlier and more efficiently. Dr. Phillips also will present data illustrating how imaging can be use...

Newly found sensing system enables certain bacteria to resist human immune defenses

...ited by what we have demonstrated—an efficient and unique way that gram-positive bacteria control resistance—and we are continuing our investigation of the aps sensing system being used for drug development.” ...

New findings challenge established views on human genome

...tion” by acting as a source of functional elements unique to each species and of elements that perform the similar functions among species despite having sequences that appear dissimilar. Other highlights of the ENCODE work include: Identification of numerous previously unrecognized start sites for ...

Exploring the dark matter of the genome

...s were assembled by comparing numerous copies with unique or sufficiently distinctive sequences. The assembly was checked by matching it to clones of longer sequences. With the painstaking manual assembly taken as far as practical, the researchers mapped the sequences to their physical locations on the chro...

UCF nanoparticle offers promise for treating glaucoma

A unique nanoparticle made in a laboratory at the University of Central Florida is proving promising as a drug delivery device for treating glaucoma, an eye disease that can cause blindness and affects millions of people worldwide. “The nanoparticle can safe...

Weizmann Institute scientists develop a general 'control switch' for protein activity

...emical Research Support, have recently developed a unique “switch” that can control the activity of any protein, raising it several-fold or stopping it almost completely. The method provides researchers with a simple and effective tool for exploring the function of unknown proteins, and in the future the ne...

Researchers discover 'acquired' DNA key to certain bacterial infection

...was acquired from another bacterium because of its unique nucleotide structure, which differs from its Mycobacterium cousins. Such evolution likely took place over thousands of years, he pointed out, and may have come from a pathogen which also has the ability to infect environmental amoeba....

Researchers develop buckyballs to fight allergy

Antarctic icebergs -- Hotspots of ocean life

...from our shore-based labs, and to preserve it as a unique snapshot of these iceberg ecosystems at this point in history.” Using SDSC-developed technologies, Helly collected the data using the SIOExplorer-in-a-Box digital library system ( http://SIOExplorer.ucsd.edu ) and then stored the information in c...

Skimmed milk -- Straight from the cow

... to breed commercial herds producing milk with the unique characteristics required to make a butter that is spreadable straight from the fridge. They have already identified a cow, Marge, with the genes required to do this and say a commercial herd is likely by 2011. The milk is very low in saturated fats a...

New designer lipid-like peptide with lipid nanostructures for drug delivery systems

'Insulator' helps silence genes in dormant herpes virus

... reinvent the wheel by making its own proteins and unique structures," she says. The researchers now plan to study the HSV-1 insulator in mice to see how the mechanism works to block the communication of gene-activating elements such as enhancers and promoters. The group is also working to identify any a...

Amphibians in losing race with environmental change

...nough to deal with these changes. Because of their unique characteristics, the amphibians are just the first to go." In their analysis, the OSU scientists point out that evolution is not a precise or perfect process - it takes time, is constrained by historic changes and compromises, and does not always...
