Researchers discover way to make cells in the eye sensitive to light

...eate a functionalphotoreceptor. It is an important proof of principle that melanopsincan make non-light sensitive cells receptive to light, and although nota cure, could have applications in treating some forms of blindness."Dr Rob Lucas, from the University of Manchester, and one of the paper'sauthors, ad...

Study Links Ebola Outbreaks To Animal Carcasses

... deadly outbreaks." The paper provides definitive proof for the assumption that Ebola moves from wildlife populations to humans through the consumption or handling of carcasses or bushmeat. Specifically, the researchers found that Ebola infections in wild animals such as gorillas, chimpanzees, and occasi...

Purdue proves concept of using nano-materials for drug discovery

...ical engineering. "What we are reporting now is a proof of concept," said Lee, one of three researchers who wrote a paper that details new findings in the current issue (Feb. 15) of the journal Langmuir. The two other researchers are Zhigang Wang, a postdoctoral fellow at Purdue; and Richard Haasch, a res...

Researchers find missing genes of ancient organism

...like Nanoarchaea operate gives clues to -- but not proof of -- the relationship between modern and ancient organisms. ### Other authors on the paper include Lennart Randau and Michael J. Hohn from Yale, and Richard Münch and Dieter Jahn from the Technical University Braunschweig, Germany. This work was s...

New SARS Protein Linked To Important Cell Doorway

...he organisms never use, and the researchers had no proof yet that SARS actually made use of the sequence their analysis identified. Geneticists call such sequences of genetic information open reading frames, and the SARS sequence therefore came to be known as open reading frame 7a, or orf7a. To produce th...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...a living rodent. Their findings, which represent a proof of principle for the use of emissive polymersomes to target and visualize tumors, appear in the Feb. 7 online early edition of the Proceedings of the National Academy of Science. "We have shown that the dispersion of thousands of brightly emissive m...

Chemists identify key gene in development of type 1 diabetes

...in the formation 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 ...

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

Silence the gene, save the cell: RNA interference as promising therapy for ALS

...ng a single delivery mechanism. "This is the first proof of principle in the human form of a disease of the nervous system in which you can silence the gene and at the same time produce another normal form of the protein," notes Patrick Aebischer, EPFL President and a co-author of the study. ALS is a prog...

Used in a new way, RNA interference permanently silences key breast cancer gene

Anammox bacteria produce nitrogen gas in oceans' snackbar

...copy and DNA analyses of water samples was used to proof the abundance of anammox bacteria in the Atlantic Ocean. The discovery of anammox bacteria in the open ocean has major consequences for our understanding of the global nitrogen cycle. Models of global nitrogen budgets, which play an important role in...

Grizzlies set to invade high Arctic?

... 2004, Dr. England's research group found physical proof that a grizzly bear was indeed calling Melville Island home. Near a cabin used by researchers for temporary stop-overs, they found grizzly bear paw prints in the mud. And from the cabin's outside walls and a guy wire attached to the roof they collect...

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years

The dramatic decline in measles deaths is made possible through the commitment of governments to fully implement the WHO/UNICEF strategy for sustainable measles mortality reduction. The str...

Microarrays as phenotype

...hematical support for these findings." "This is a proof of principle that we set out to do ?assessing the function of unknown genes is feasible," said Shaulsky. "It can be done with a microarray phenotype." Others who participated in the research included Drs. Nancy Van Driessche, Ezgi O. Booth, Paul Hil...

Human Eggs Can Develop From Ovarian Surface Cells In Vitro

...lation to release mature eggs. However, definitive proof that new oocytes may develop in adult human females will be if they can be found to differentiate in vitro from OSE cells derived from adult human ovaries. For the first time, Antonin Bukovsky and colleagues from the Department of Obstetrics and Gyn...

Life detection instrument passes key test on road to Mars

...ype of handedness over another - would be absolute proof of life," said Mathies, professor of chemistry at UC Berkeley and Skelley's research advisor. "We've shown on Earth, in the most Mars-like environment available, that this instrument is a thousand times better at detecting biomarkers than any instrum...
