Huntington's cure in flies lays groundwork for broader treatment approaches

...one type of tissue," says Yin. "And we are not yet sensitive to detecting the defects in those other tissues." Rather than focusing treatment strategies on single genetic pathways, then, Yin believes a promising alternative might be to simultaneously target a cocktail of gene-induced activities - all of which...

Weight control protein may yield antiobesity drugs

...ions in cells throughout the body, keeps the brain sensitive to the fat hormone leptin, found researchers from the University of Michigan Medical School. Produced by fat tissue, the leptin hormone sends signals to the brain about the body's fat content. That signal, in turn, elicits adjustments in appetite and...

Global warming increases oyster sensitivity to pollution

...lains, "these organelles become significantly more sensitive to cadmium as temperature rises, so that cadmium levels which were not damaging to mitochondria at lower temperature become strongly toxic with increasing temperature." Cadmium circulates continually between air, water and soils. As it moves easily ...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...re is a hybrid of two molecules that are extremely sensitive to outside signals: single stranded DNA, which ser...notubes have many applications, they are extremely sensitive to electrostatic variations in their environment, whether the nanotube is in a liquid or in air. "W...

Researchers find how some antibiotics kill bacteria

...to one kind of rifamycin antibiotic might still be sensitive to another. "That may help to narrow down the search for new synthetic derivatives to conquer resistance altogether." The study appears in the current issue of the journal Cell. Ryfamycin antibiotics are one of the first-line treatments for tuberc...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

...d to provide alerts days in advance so that people sensitive to pollutants can modify planned outdoor activities to minimize their exposure. The troposphere is where we all live, work, play and breathe! It's the region of the atmosphere where our weather occurs and it extends from the Earth's surface to rough...

UCLA researchers identify key enzyme linked to childhood blindness

...t characteristic of this disease is that the light sensitive rod and cone cells remain intact in the retinas of Leber patients for a long time. "This suggests that replacement of RPE65 by gene therapy should correct the blindness in these children, as was observed in mice and dogs with RPE65 mutations," Travi...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

... smaller the focal volumes, the more effective and sensitive are these methods. Fluorescence fluctuation methods were also limited by diffraction as a result. Therefore, in a fourth study [4], the research team from Göttingen shows that using STED, measurement volumes notably below the resolution limit can be ...

Skull study sheds light on dinosaur diversity

... through these holes and may suggest an especially sensitive snout. This probably had some role in feeding, but we haven't investigated it at all." Oddly, a group of distantly related sauropods evolved a similarly grooved snout. "Apparently, these two different branches of sauropods gravitated toward similar ...

Water management in cells

...the cell. Tomassen studied cells that are highly sensitive for osmotic disruption. He discovered that cells permeable for water can more easily respond to changes in salt concentrations and that volume changes are facilitated by the presence of specific channels that transport water. Slow organic reaction...

New tooth enamel dating technique could help identify disaster victims

...lerator mass spectrometry is becoming increasingly sensitive and inexpensive, suggesting that even though nuclear testing was conducted decades ago, enamel dating could be used for precise age determination "for a long time to come." ...

Drugs from the deep blue

...lopments in analytical chemistry, including highly sensitive instrumentation, sophisticated screening capabilities and discoveries from mapping the human genome, have created a renaissance of interest in these sources of potential medicines. Molinski's laboratory studies the chemistry and biology of marine na...
