Researchers discover chemical compounds that affect plant growth

...rupt gene function," Raikhel said. "The underlying concept is that the functions of most proteins can be altered by the binding of a chemical, which can be found by screening large libraries for compounds that specifically affect a measurable process." The scientists found 219 chemicals that affected the di...

Biodiversity hotspots identify conservation priorities

...t assessment underscores the value of the hotspots concept for defining urgent conservation priorities," said...re the uniqueness of life on Earth." The hotspots concept was pioneered in 1988 by British ecologist Norman Myers, who recognized that hotspot ecosystems (mos...

Polymers with copper show promise for implanted sensors

... the skin. Much work remains to be done, "but the concept of using immobilized copper ions is what we're putting a lot of thought into these days," said Meyerhoff. "It's a speculative idea, but if it works, it will be very exciting." ...

NASA links nanobacteria to kidney stones and other diseases

...k for crew members living in close quarters. "The concept that nanobacteria are living organisms is still controversial because the research on their putative nucleic acid has not been completed yet," states lead researcher Neva Ciftcioglu, Ph.D. However, the group's research provides additional clues to un...

Artifical cornea lets woman blind 20 years see

...f modern cornea science. Dohlman has developed the concept of one such keratoprosthesis for more than forty years. Despite his advancing age of 82, Dohlman has managed to refine a type of artificial cornea widely known as the Boston keratoprosthesis. He has made more than 300 of the devices himself, but hol...

Mayo Clinic Researchers Create 'Obedient Virus'; First Step To Use Measles Virus Against Cancer

...ll years away from use as a human therapy. But the concept has at last been proved in mice with human cancer tumors -- and that's an essential step toward using this approach to expand and improve human treatments for a variety of cancers. The "Obedient Virus" "When I saw the data, I was completely stunned...

Towards precise classification of cancers based on robust gene functional expression profiles

...rmation of diabetes, the finding provides proof of concept that efforts to block the formation of this particular protein is a promising approach for fighting diabetes, they say. "The MIF gene may be regulating other genes involved in type 1 diabetes," says Al-Abed. "We don't know yet, but we're looking int...

Gene therapy for Parkinson's disease moves forward in animals

... in the brain. "Our strategy is a neuroprotective concept and would only be amenable for early stage patients to keep a good quality of life. It would be a huge change in the way treatment is done," said Mandel, a neuroscientist in UF's College of Medicine. "We know the GDNF protects the neurons in primates...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

Purdue proves concept of using nano-materials for drug discovery

...e has nanometer-scale pores in it," Lee said. "The concept is fairly simple - there is an inorganic porous membrane - in this case alumina, which separates the reaction chamber from a solution. The pores in this membrane are nanometer in scale, so they do not allow proteins to readily pass through the membra...

Newly-discovered class of genes determines ?and restricts ?stem cell fate

...hile never growing old." Epstein thinks that this concept may also be important for understanding the cell of origin for a number of tumors. Pax3 is known to be involved in some tumors, which adds evidence to the stem-cell origin for some cancers. This theory proposes that many cancers may arise from normal...
