Interaction of just 2 genes governs coloration patterns in mice

...n Harvard's Faculty of Arts and Sciences. "It also illuminates the pathway by which these two genes interact to produce distinctive coloration. There's reason to believe this simple pathway may be evolutionarily conserved across mammals that display lighter bellies and darker backs, from mice to tuxedo cats to G...

Scientists gain important insights into acute promyelocytic leukemia

... the journal Cancer Cell, published by Cell Press, illuminates specific mechanisms involved in development of acute promyelocytic leukemia (APL) and identifies promising new avenues to develop treatments for some of its variant forms. APL is a cancer of the bone marrow that occurs when certain developing white...

Mucosal-surface immune function discoveries could boost vaccine research

...rch, new research at Weill Cornell Medical College illuminates the ways in which the body prevents its mucosal surfaces from being overwhelmed by bacteria. Bacteria, most of them "friendly," appear in huge quantities along the intestinal wall, the mouth, nose and throat, and the anal and urogenital tracts. Now...

AGU Journal highlights -- February 23, 2007

...ea heights reveal deep pressures A new analysis illuminates when and where sea-level height provides an accurate gauge of ocean-bottom pressure. Using simulations, Vinogradova et al. studied the relationship between those ocean characteristics as a function of timescale, bottom topography, and geographic loca...

ACS News Service Weekly PressPac -- Nov. 1, 2006

...viously developed a bright fluorescent sensor that illuminates in the presence of NO. Visible under the fluorescent microscope, the sensor will help scientists see where and when NO is produced in cells, and perhaps uncover the chemical signals that trigger production. The research demonstrates that the sensor...

Research linking Ashkenazi Jews and breast cancer genes beset by problems

... self-identification problematic. The study also illuminates how geneticists interpreted Jewish history to support the theory of Ashkenazi genetic uniqueness. This interpretation views the historic Ashkenazi Jewish population as isolated, and as having undergone extreme expansions and contractions. It attribut...

Scientists reverse evolution

...construct the ancient gene they split off from. It illuminates the mechanisms and processes that evolution uses, and tells us more about how Mother Nature engineers life." The ability to reconstruct an ancient gene from descendant genes also raises the possibility of a new type of gene therapy, in which a por...

Scientists elucidate the kinome of key model organism

...n which to study conserved cellular processes, and illuminates a period in the evolutionary history of the metazoa after the divergence of the plants but before that of the fungi. "Our findings document the impressive evolutionary creativity of the Dictyostelium kinome- a large portion of the kinases are unique...

New cell imaging method identifies aggressive cancer cells early

Fluorescence that illuminates a specific protein within a cell's nucleus may be a key to identifying cancer virulence and to developing individualized treatment, according to researchers at Purdue University and Lawrence Berkeley National Laboratory. The scientists created a tech...

Quantum cascade lasers key to handheld gas and liquid sensors

...e wavelength of light very well. So when the laser illuminates the gas molecules inside the waveguide, the waveguide will propagate only the selected fingerprint frequency for detecting a specific molecule. "In our paper, we've shown that if we take only one meter of photonic band gap hollow waveguide with an in...

Light-sensing protein illuminates sun-loving ocean bacteria

...ited to capturing the high-radiation sunlight that illuminates the sea. Through the use of meta-genomic analysis, the authors also observed great diversity among proteorhodopsin genes. Estimating the average size of the bacterial genome led Beja and colleagues to the conclusion that about 13% of ocean bacter...

Hummingbird flight an evolutionary marvel

The research was done with rufous hummingbirds, a migratory species common in Oregon...

Dye to pinpoint diseases and pathogens

...e DNA that binds to specific target DNA sequences, illuminates in the presence of a targeted pathogen or genetic mutation and then sends a detection signal through an optical fibre. By simply adding heat, the dye unbinds and the detection chemistry is ready to test the next sample. The chemical screening system ...

Efforts to clone primates move forward
