New technique could alter field of mouse genetics

...-- mutate each gene, observe the consequences, and investigate the molecular mechanisms. In the past two decades, only about 3,000 of the estimated 25,000 genes shared by mice and humans have been analyzed in detail, Xu said. A reliable gene-transposing tool could make that job much easier and quicker. Xu and h...

Nanotubes inspire new technique for healing broken bones

...ore proceeding to clinical trials, Haddon plans to investigate the toxicology of these materials and to measure their mechanical strength and flexibility in relation to commercially available bone mimics. ...

Acid water in East Java threatens biodiversity and local welfare

She went to investigate the local ecology. Yet during her field work on East Java, Dutch biologist Ansje Lohr became increasingly involved with the local residents, whose harvests failed and whose health was deteriorating due to extremely acidified and polluted river water....

UW-Madison scientists zero in on drugs' sweet spots

...ritically, the method allows medicinal chemists to investigate the biological effects of the many forms of sugars or carbohydrates found in nature. "There are many different variations of sugars -- they're all over the place in nature -- and they are very important. This method allows us to rapidly scan the role...

An essential regulator of body weight revealed

... in adults, Palmiter said the next step will be to investigate what makes them so important. He and his colleagues have already begun experiments to test specific molecules that might contribute to their essential role. ...

NC State researchers redesign life for Mars and beyond

...Virtual Plants" and plan to offer another class to investigate new mechanisms for reducing radiation damage in spring 2007. ...

Beach pollution is worst during new and full moon

...t to improve water quality at their beaches should investigate the potential of these sources to be contributors of enterococci to marine waters." Boehm cautions that enterococci from beach sands and wrack may not correlate with health risk the same way as enterococci from runoff or sewage. "We just don't know ...

Plants reveal a secret and bring researchers nearer a cleaner future

... European Synchrotron Radiation Facility (ESRF) to investigate the kinetics of the photosynthesis process. They have confirmed the existence of a fifth step in the catalysis process of water into oxygen, and have published their results in Science. Chlorophyll in plants absorbs light from the sun, which then be...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...ospheric ozone, but were also selected in order to investigate the amount of useful information that could be retrieved from the troposphere. "The instruments are now being used to monitor a significant number of key tropospheric trace gases including formaldehyde, methane, sulphur dioxide and carbon monoxide ...

Study reveals genomics of inflammation from severe injury

..., but how those genes interact with each other. To investigate this, the group turned to a knowledge base compiled by Ingenuity Systems, Inc. of Mountain View, Calif., that includes 200,000 published reports on more than 8,000 human, rat and mouse genes and their genetic interactions. This tool enabled the group...

Dangerous tricksters: Some bacterie use immune cells to reproduce

...rial.' The next aim of the Bonn researchers is to investigate which bacterial features are important for preventing the merger of phagosomes and lysosomes, and how the immune system normally successfully eradicates an infection despite all the tricks the bacteria use. Rhodococci, incidentally, can also cause d...

New study expands understanding of the role of RNA editing in gene control

... formation. "A couple of years ago, we started to investigate whether miRNA precursors were being edited in processing," says Kazuko Nishikura, Ph.D., senior author on the study and a professor in the gene expression and regulation program at The Wistar Institute. "We found that about half of all miRNA precurso...

Neurons generated in the adult brain learn to respond to novel stimuli

...level structure. The current study was designed to investigate whether newly generated olfactory neurons simply replace older neurons or play a distinct role in learning and memory. The investigators used two groups of mice whose precursor cells had been labeled to mark those that were dividing, allowing ident...

Do the Europeans turn ill sitting up so late?

...an research and training network was establishedto investigate the causes and implications of poor sleep from the medical as well as from the social point of view. This EU-financed sleep research project, named"The biomedical and sociological effects of sleep restriction" will last for four yearsand is coordinat...

Limiting the damage in stroke

...ike condition in mice, a model that can be used to investigate new therapies. What would happen if the activity of NF-kB in neurons were blocked after a stroke? To test this, genetic mouse models were required. The group of Manolis Pasparakis at EMBL's Mouse Biology Unit developed a strain of "conditional knock...

Cord blood cells may widen treatment window for stroke

...r. Willing said. The USF researchers continue to investigate the ways cord blood cells aid stroke recovery in animals, and will begin a study to determine the timing of brain inflammatory responses in acute stroke patients. Researchers working with Dr. Willing were Jennifer Newcomb, Ted Ajmo, Lisa Collier, Cy...

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

...xamined in cells. In this way, the researchers can investigate the benefits of hyper-responsive Stat1 for infection control and cancer treatment in a living organism. These studies lay the foundation for the development of human treatments that use drugs that increase Stat1 responsiveness and consequently enhanc...

Meditation associated with structural changes in brain

... mediation as a central focus of their lives. To investigate whether meditation as typically practiced in the U.S. could change the brain's structure, the current study enrolled 20 practitioners of Buddhist Insight meditation ?which focuses on "mindfulness," a specific, nonjudgmental awareness of sensations, f...

Overfishing may drive endangered seabird to rely upon lower quality food

...l investigator of the study. "What better place to investigate this process than in Monterey Bay, where sardines once were king and Cannery Row formerly stood?" The researchers decided to embark on this study when they noticed that the population of 600 marbled murrelets they were studying in central California...
