New winter hulless barley has high protein

...ogram continues to work on more new cultivars that help provide solutions to agriculture problems. Another of the projects aims to develop wheat and barley cultivars resistant to pests and so require fewer chemical inputs. For example, producers would obtain higher yields of a safer and higher quality gra...

Scientists discover how plants disarm the toxic effects of excessive sunlight

...cals that target this response, and ultimately may help us mitigate disease." Donohue's co-authors on his study were a microbiology graduate student, Jennifer Anthony, and a bacteriology undergraduate, Kristin Warczak. The project was supported by a grant from the National Institute of General Medical Sc...

Multi-purpose protein regulates new protein synthesis and immune cell development

...perone proteins to assist with protein folding and help with protein trafficking. And third, it activates genes involved in protein degradation to get rid of excess unfolded proteins. So you reduce the load, get rid of garbage and increase efficiency. If these don't work, the cell will die." "Recently, s...

Gene therapy promising for growing tooth-supporting bone

...etic machinery. Once inside the cell, the viruses help BMP-7 genes get where they need to be in the host's cells to boost bone production. Gene expression producing BMP-7 proteins peaked after a week. Giannobile said that was ideal because the team did not want to make any permanent genetic changes. The ...

Gray wolves maintain the food chain in winter

... models described here can guide their efforts and help species adjust to major environmental shifts like climate change. Crucially, Wilmers and Getz's study shows that a robust food chain - including this still embattled top predator - may be even more important as ecological conditions deteriorate. ###...

Computational Method Speeds Mapping of Cell Signaling Networks

...e signaling networks at once. This new work should help bridge that gap. Human T-cells--the system Nolan and Lauffenburger's team used to validate their technique--rely on a complex signaling network to protect the body from pathogens such as viruses. When a T-cell encounters a foreign invader, it relays...

Glow-in-the-dark zebrafish at UH hold keys to biological clocks

...ahill said. "Ultimately, this type of research can help with tracing why humans develop such things as sleep disorders or mental illnesses like depression." Per3 is the naturally occurring clock-regulated gene. The protein that it encodes is produced at highest levels near dawn, and when the luc gene is ...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

...nomy, this form of renewable energy production may help offset the substantial costs of wastewater treatment as well as provide a contribution to nations able to harness hydrogen as an energy source," Logan notes,. The new approach is described in a paper, "Electrochemically Assisted Microbial Production...

Microbial forensics: The next great forensic challenge

...(DHS) and operates in partnership with the FBI. To help identify the most pressing gaps in the science and operation of microbial forensics, there was a meeting this past spring sponsored by DHS, with the results reported to the White House. The FBI-led Scientific Working Group on Microbial Genetics and F...

Navigating an integrated yeast network

...s that can be tied to biological phenomena and may help represent more fundamental network design principles than do simple motifs. Zhang et al. integrated five different types of biological relationships found in the yeast Saccharomyces cerevisae: protein-protein interactions, genetic interactions, tran...

Harmful chemicals may reprogram gene response to estrogen

... Schwartz, M.D. "If this model is correct, it will help doctors to determine which individuals are more likely to develop cancers of the uterus, breast and prostate." The finding should alert doctors to ask more questions about a patient's early-life exposures to chemicals and other harmful agents in ord...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

... Massachusetts joined forces and developed gear to help marine mammals detect and avoid gillnets before coming into contact with them, as well as allow them to escape unharmed if they still become entangled. To create avoidable, detectable, safer gear, the team tinkered with the chemical properties of the...

Scientists identify genetic pathways essential to RNA interference

...in the gene-silencing mechanism, which someday may help to fight human disease. The report will appear in ...NAi occurs naturally in plants and animals and may help control resistance to viral infection, among other functions. For the current study, lead author Jo...

Brain-mapping technique aids understanding of sleep, wakefulness

Protein That Promotes Survival Of Stem Cells Might Be Key To Poor Leukemia Prognosis

...1 in apoptosis and how this gene is regulated will help my lab at St. Jude understand why some cases of leukemia are so difficult to cure," Opferman said. "The more we understand these diseases, the more likely we'll be able to design improved treatments for them. This fits into the St. Jude mission of fi...

Revolutionary nanotechnology illuminates brain cells at work

...ized in individual brain cells, in real time, will help researchers better understand disease processes and construct new drugs." "FRET is like two musical tuning forks, which have the same tone," Okumoto continued. "If you excite one, it gives a characteristic tone. If you bring the second fork close to...

FDA Announces Series of Changes to the Class of Marketed Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

...ling to include a Medication Guide for patients to help make them aware of the potential for CV and GI adverse events associated with the use of this class of drugs. In addition, FDA is asking the manufacturers of all OTC NSAIDs to revise their labels to include more specific information about the potent...

Small species back-up giant marsupial climate change extinction claim

...cape. The findings, which were unearthed with the help of amateur fossil hunter, Ian Sobbe, are of particular significance because the Darling Downs fossil deposits are among the youngest Australian megafauna deposits - laid down on the cusp of the extinction event. PhD researcher Gilbert Price, of QUT'...
