Autism gene identified by researchers at Yale working with a global research consortium

...hed in the journal’s March print edition. They are based on the largest-ever autism genome scan. Over 120 scientists from over 50 institutions who formed the Autism Genome Project (AGP) performed the research. The AGP began in 2002 when researchers from around the world decided to collaborate and share the...

Indicators for risk of heart disease are higher in passive smokers

...uring cotinine levels compared to previous studies based on self-reported exposure. The association changed little even after researchers adjusted for participants' self-reported fruit and vegetable consumption ?one of the more influential aspects of diet on cardiovascular health ?and for lifestyle fact...

Biologists develop large gene dataset for rice plant

... (small RNAs) in rice. The analysis of rice was based on gene sequences representing nearly 47 million mRNA molecules and three million small RNAs, a larger dataset than has been reported for any other plant species. Small RNAs are considered one of most important discoveries in biotechnology in the ...

Fighting to keep Darwin in the classroom

...telligent design." The battle to keep religiously based explanations of the history of life—especially human life—out of the science curriculum continues unabated. And though a number of educational institutions and organizations have had notable success in combating intelligent design in the classroom, ...

ESA launches new project to protect biodiversity

...the project will provide a global map of dry lands based on existing global datasets to the UNCBD. The DIVERSITY project, developed under ESA's Data User Element (DUE) programme, is being carried out in collaboration with the UNCBD Secretariat and UNESCO, which, in addition to being a user, is also the ...

'Night owls' report more insomnia-related symptoms

...d as morning, intermediate and evening chronotypes based upon scores on the Morningness-Eveningness Composite Scale. Group comparisons were made on self-report measures of nocturnal sleep, sleep period variability and waking correlates and consequences of insomnia. Compared to the morning and intermedi...

Scientists find method to pick noncompetitive animals, improve production

...rlands and England designed mathematical equations based on traits to choose animals that are more congenial in groups, said William Muir, a Purdue Department of Animal Sciences geneticist. The new method is a tool that may contribute both to animal well-being and to securing the world's future food supply...

University of Alberta researchers unravel intricate animal patterns

...movements--that emerge from the ‘bottom up? simply based on interactions between neighbors." Until Eftimie’s work, these complex emergent patterns could not be connected clearly to simple rules for the small scale communication between individuals. People have had some success in proposing rather com...

Ancient amphibians evolved a bite before migrating to dry land

...f the National Academy of Sciences. Their work is based on analysis of the skulls of the first amphibians, which arose 375 million years ago, and their fish ancestors. The shapes of the junctions between adjacent skull bones -- termed "sutures" -- in the tops of these fish and amphibian skulls reveal how ...

Protein overexpression at heart of heart failure

...conclude that electrical remodeling of the L-VDCC, based on gene expression changes, is an early step in a cascade ultimately induced in heart failure. This provides a rational framework for novel therapeutic intervention in heart failure. ...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...rch (TIGR), a not-for-profit research organization based in Rockville, Maryland. Dr. Carlton is now an associate professor in the Department of Medical Parasitology at New York University's School of Medicine. Although it is not entirely clear why the genome is so large and repetitive, researchers theo...

Elucidation of the genome for diabetics with DNA chips

...was developed in the United States. This method is based on the use of DNA chips, with a surface of only a few square centimetres, carrying almost half a million DNA mutations. Each of these chips can be used to dissect the entire genome of an individual. Initially, DNA from non-obese patients with ty...

Scientists find potential 'off-switch' for HIV virus

...ough more research will be needed to develop drugs based on the Princeton scientists' "resistor" model, Weinberger said he hopes the discovery stimulates more research into potential gene-targeted therapies. "It would be wonderful to learn more about how these genetic circuits work so that we can enter...

Homing pigeons get their bearings from their beaks

...oration with HASYLAB, the synchrotron laboratories based in Hamburg, Germany, iron-containing subcellular particles of maghemite and magnetite were found in sensory dendrites² of the skin lining the upper beak of homing pigeons. This research project found that these dendrites are arranged in a complex th...

Scripps research study reveals structural dynamics of single prion molecules

...ultiple proteins in an aggregate). The technology, based on measuring fluorescence bursts from individual tagged proteins, enabled the scientists to determine that the proteins being studied were, in fact, single monomers and not aggregates. Deniz said that future work with yeast prion mutants might re...

Is there a pilot in the insect?

...ope. They then produced an electronic microcircuit based on this principle. The most recent version weighs only 0.2 grams. This is the neuron that does most of the work on board the microhelicopter. The optic flow regulator helps explain how an insect manages to fly, even in unfavorable wind conditions, ...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...argeting p53. "Instead of creating a vaccine based on mutant p53, which would require a custom vaccine for every patient, our strategy is to target parts of the unaltered p53 protein that can best activate the immune system," said Theresa Whiteside, Ph.D., professor at the University of Pittsburgh ...

Gene that makes people 'early to bed and early to rise' demystified

...rmation we've had about these clock genes has been based on the Drosophila model and Per2 knockout mice," which lack the Per2 clock gene altogether, added study author Ying-Hui Fu, who is also at UCSF. Based on those studies, "everybody had thought a short or long period depended on a change in protein ...

Failure to meet United Nations sanitation target could affect millions of the world's poorest

...t the needs of the world's poorest." The target is based on data from 1990, when 20 percent of the global population lacked a safe source of drinking water and 45 percent had no access to sanitation facilities. Now, halfway to the deadline, experts warn that the United Nations is on track to achieve only p...
