The blotchier the face, the better the wasp

...a liability in the wasp world, Tibbetts said. As a final test of their hypothesis, the researchers decided to stage some fights where one wasp had been experimentally altered so her face didn't reflect her true quality. After chilling wasps in a refrigerator, Tibbetts used a toothpick to apply Testor's mod...

Researchers discover molecular timekeeper in bone development

...the early timing of osteogenesis by preventing the final step, bone hardening from occurring. By specifically blocking a protein called Runx2, which controls the genes for bone hardening, HDAC4 allows the foundation and minerals to be properly laid before hardening can occur. Dr. Olso...

Safety of bismuth bullets questioned: Study

... at the University of Toronto at Scarborough. "Our final recommendation is to abandon bismuth and use steel shot until further research is completed." Gough, along with graduate student Ruwan Jayasinghe and colleagues from McMaster and Queen's universities and the University of Waterloo, examined the ba...

Study identifies molecular complex vital to creation of miRNAs

...t be cut into small precursor RNA molecules before final processing into mature miRNAs. The finished miRNAs are remarkably small, only 22 nucleotides in length, but powerful. These molecules appear to work by binding to complementary regions in messenger RNA, responsible for translating genes into proteins...

A puzzle posed by black-headed ducks yields to persistent biologists

...e contents of nests. It was only in the fourth and final year of the study that the importance of intraspecific brood parasitism became apparent. "For some reason it was really prevalent and noticeable that year, and finally we had an explanation for the anomalous results we had been finding," Lyon said. R...

Scientists develop 'electronic eye' for the blind

...ar the ear". The device developed at Kyoto is the final product of a research programme that aimed to give blind people all the navigation information they needed to cross a road from a single small camera. Last year, the authors announced that they had designed a computer-aided camera that could measure ...

What women want makes a difference

...y of speciation as they provide vital clues to the final stages of the speciation process. Ortiz-Barrientos and colleagues are now poised to identify and study the evolution of the actual genes contributing to the creation of new species. ...

Visualizing the end of the human genome

...up of a repeating sequence of six nucleotides. The final 100 to 300 nucleotides at the very end extend beyond the double helix as a single-stranded DNA "tail." The telomeres of normal cells gradually become shorter and shorter with each cell division, a characteristic sign of cellular aging. But cells ...

Census of Marine Life - Discoveries and Highlights 2004: Scientists add 4m+ records, 13,000 species

...e fish species to 15,482. CoML experts expect the final count to total roughly 20,000. The database includes more than 6,800 species of zooplankton, animals that drift with the currents. They expect to discover, identify, and add at least as many zooplankton species to the database over the ...

HIV research project scoops innovation prize

...-year programme of further tests which will be the final stage of the pre-clinical work." Dr Dobson's research also found that the chemicals, known as apolipovirs, also have anti-bacterial properties and could help prevent the spread of other sexually transmitted diseases, like Chlamydia and syphilis, whic...

New pheromone creates buzz about the clout of older bees

... by the elder bees, those that typically spend the final one to three weeks of their five-week lifespan out in the field. Experiments showed that if a significant number of forager bees didn't come home, the young nurse bees would mature ahead of schedule and head out to become foragers themselves. If the...

Researchers reconstruct parts of the genome of a common mammalian ancestor

...es that lived tens of millions of years before the final demise of the dinosaurs. This species underwent a rapid diversification, splitting into the evolutionary lineages that have led to today's placental mammals. Because all of these species are descended from a common ancestral species, they all have in...

Save up your energy reserves for a longer life!

... body as a source of energy and generates AMP as a final product. Apfeld's group focused on an enzyme, called AMP-1, that is specifically activated by high levels of AMP and results in a cascade of reactions that work to conserve energy stores. Using an array of genetic and molecular tricks on nematode wo...

Chicken genomic sequence yields insight into vertebrate evolution

...into tandem arrays, causing major problems for the final genome assembly, says Robert Ivarie, Ph.D., Professor of Genetics at the University of Georgia. In his Genome Research paper, Ivarie's group reports the identification of several new repeat elements, some of which were not present in the publicly av...

First analysis of chicken genome offers many new insights

... of life, also will become useful for study of its final stages. Wilson compares the chicken genome and other genomes to Rosetta Stones scientists are using to better understand the human genome. As life on Earth evolved over time, genes have been created, kept, discarded or deactivated, and reor...

Singing in the brain

...les for putting all five segments together. In a final experiment, five sparrows heard pairs of song segments, with each pair in reverse order: BA, then CB, DC and ED. The birds again learned to string the segments together, but because the segments were reversed, they sang with the segments strung toget...
