How Fruitflies Know It's Time for Lunch

...abnormal eating behavior. One group of these flies shared a mutant klumpfuss (klu) gene, normally responsible for encoding a protein transcription factor. Because neural transcription factors control production levels of other neural proteins, the researchers used DNA microarrays to compare gene expression ...

Same-sex mating by fungi spawned infection outbreak, evidence suggests

...ncisco in 1992. What's more, the Canadian strains shared approximately half of their genetic makeup, suggesting that the two might be related. Further analysis confirmed this initial finding, suggesting that the two C. gattii strains in Vancouver Island are either siblings or that one is the parent and the...

Scientists map one of biology's critical light-sensing structures

...illion or so years ago in a common ancestor and is shared among not only bacteria, but also by plants and fungi. "This is probably the most important light regulator in agriculture," says Richard Vierstra, a UW-Madison plant geneticist and one of two collaborating senior authors of the Nature paper. "It te...

Did feathered dinosaurs exist?

...rectly from advanced theropods, or from an earlier shared ancestor. The current theory supports direct derivation, but recent fossil discoveries in China have led to new questions about the claim. The Chinese discoverers reported finding all stages of feather evolution and ancestral birds, even though the d...

Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see

...mes in both neurons, this indicated that they both shared the same inputs. The Salk scientists found that the thousands of neighboring neurons that make up these columns are not the same, and they often don't communicate directly with each other. In February, they reported in Nature how excitatory neurons ...

Cornell finds natural selection in humans

...evolution in the last 5 million years, when humans shared a common ancestor with chimps. Likewise, the researchers found that approximately 13 percent of the genes that may vary show evidence of slightly deleterious or harmful mutations in human populations; these include genes involved in determining the...

A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...s group made a striking observation: All 635 genes shared between the two genomes were completely conserved in terms of order and strand orientation. This is a remarkable observation, given that bacteria are particularly noted for their rapidly evolving genomes characterized by extensive recombination, gen...

New research puts a fresh spin on current thinking of speech evolution in humans

...'s area is in a unique position to use information shared from past experience and which is stored in memory for the service of communicative acts," explains Dr. Petrides. "That is, Broca's area may have evolved originally as an area exercising high-level control over oral and facial actions, including thos...

US/African project deciphers deadly parasite genome

...IGR determined the genome sequence of T. parva and shared in the annotation of the genome ?the identification of genes and the assignment of gene functions ?with scientists at ILRI. Much of the annotation of the T. parva genome was performed by two bioinformatics specialists at ILRI. "ILRI's involvement in...

Virginia Tech football player uses prototype cast

...." Love added that the new bracing system will be shared with the trainers at Wake Forest. Further bracing enhancements may evolve from the efforts of the students who may have developed even higher performing designs for the longer term than the commercial "off the shelf" solution. ...

Micro RNAs play role in egg making

...tion, they found that the genes affected by miRNAs shared common roles as regulators of protein manufacturing or turnover. These results suggest that miRNAs tightly control the abundance of proteins throughout the process of oogenesis and fertilization. Using a proteomics tool developed at Carnegie Mellon,...

DNA traces evolution of extinct sabertooths and the American cheetah-like cat

The work is reported in the August 9 issue of Current Biology by Ross Barnett of the University of Oxford and a team of researchers from Britain, the United States, Sweden, and ...

New technique could alter field of mouse genetics

...es, only about 3,000 of the estimated 25,000 genes shared by mice and humans have been analyzed in detail, Xu said. A reliable gene-transposing tool could make that job much easier and quicker. Xu and his colleagues at Fudan University in Shanghai, China, began their studies with a transposon called piggyB...

Evolution of life on Earth may hold key to finding life in outer space

... "Since many of the components of the ribosome are shared by all organisms, we know this machinery is very, very old," Fox said. "If we can discover the earliest aspects, then scientists may be able to devise experiments to see how simple RNAs might have given rise to this machinery. This information would ...

Progress on HIV/AIDS significant but insufficient

United Nations Secretary-General Kofi Annan shared his hope with a gathering of senior world officials at Headquarters that the 2001 Declaration of Commitment on HIV/AIDS would have heralded a response that matched the epidemic's scale, yet progress had been "significant but insufficient". Citing ac...

Team of international scientists departs today to discover the unknown in China's Himalayan region

Results from the expedition will be shared with numerous entities, such as the Chinese government, environmental organizations and scientists to develop strategies to protect the unique species of the region. At Disney's Animal Kingdom in Florida, the findings will be incorporated into the Ex...
