Utah researchers confirm chromosome may harbor autism gene

...rchers used a gene chip similar to a microarray to search for geneticmarkers of autism. They used a coated ...m, so Coon and the other U researchers began their search on that chromosome. The first region of the chromosome they looked at contained 106 SNPs, 70 of whic...

Next good dinosaur news likely to come from small packages

...proteomics. Like conventional paleontologists, the search is to reveal the history of life on Earth. But tacking on proteomics means scrutinizing life at a molecular level ?life that existed thousands of years ago. Ostrom's work has spanned from examining organic matter in meteorites to reconstructing who ...

Powerful technique for multiplying adult stem cells may aid therapies

...dramatically? Zhang used a microarray platform to search for genes that were active in these newly discovered cells, but not active in similar neighboring cells. Some such genes, he reasoned, might encode secreted proteins that sustained stem cells. Eventually, he located a number of such genes. In the...

How the brain learns to become addicted

...in and CRF may prove to be fruitful targets in the search for addiction medications." Bonci and his colleagues based their experiments on past studies by other researchers showing that orexins are important regulatory peptides released by a brain center called the lateral hypothalamus. It was also known th...

DNA conclusive yet still controversial, Carnegie Mellon professor says

...alled "cold hit" technique, in which investigators search a DNA database to find a match of DNA found at a crime scene and then collect other evidence to build their case -- as opposed to first identifying a suspect through other evidence and then using DNA to confirm their case. Some critics claimed that t...

Mice studies illustrate potential of chimp/human antibodies to protect against smallpox

...gious and fatal virus have prompted researchers to search for new smallpox vaccines and treatments. The currently licensed smallpox vaccine consists of a live but weakened strain of vaccinia virus, a relative of the variola virus that causes smallpox. Vaccinia immunization has been proven effective in gen...

GPSDB, the free Gene and Protein Synonyms DataBase

The search for El Dorado in the Amazonian rainforest might not have yielded pots of gold, but it has led to unearthing a different type of gold mine: some of the globe's richest soil that can transform poor soil into highly fertile ground. That's not all. Scie...

Fruit fly's beating heart helps identify human heart disease genes

In a discovery that could greatly accelerate the search for genetic causes of heart disease, a multi-disciplinary Duke University research team has found that the common fruit fly can serve as a powerful new model for testing human genes implicated in heart disease. The finding is important, the Duke tea...

Amazonian terra preta can transform poor soil into fertile

The search for El Dorado in the Amazonian rainforest might not have yielded pots of gold, but it has led to unearthing a different type of gold mine: some of the globe's richest soil that can transform poor soil into highly fertile ground. That's not all. Scie...

A link is found between morphine addiction and the tendency to explore

...ated to a tendency to explore perseveringly and to search for new sensations. Using mazes and cages, the scientists observed in their experiments that the animals with a greater tendency to explore are more inclined towards an addiction to morphine. The researchers had classified the rodents according to ...

Low-cost drug gaining favor for use in HIV-infected children in poor countries

... had to be a randomized clinical trial. Grimwade's search turned up only one trial that passed that litmus test: a study of 534 HIV-positive children in Zambia. The study found 33 percent fewer deaths in the group of children who received cotrimoxazole versus the children who were not treated with the anti...

'Banana-jawed' fossil mammal linked to rare sound-producing skill

...o. For several decades, Simons visited the site in search of early ape and monkey fossils, as part of his main research focus on the evolution of primates leading up to humans. During these explorations in the "Badlands of Egypt," his group collected enough specimens of Thyrohyrax to allow a systematic anal...

Researchers map of genetic variations implicated in disease

...dge Institute for Medical Research, "and the WTCCC search for the genetic signposts for eight common diseases will be accelerated by the new markers reported here. At an ever increasing rate, we are developing the necessary tools and sample collections to make a real difference to the study, diagnosis and, ...

Cortex matures faster in youth with highest IQ

...haw. The NIMH researchers are following-up with a search for gene variants that might be linked to the newly discovered trajectories. However, Shaw notes mounting evidence suggesting that the effects of genes often depends on interactions with environmental events, so the determinants of intelligence will ...

'Virus chip' detects new virus in prostate tumors

... Ganem at UCSF, using the chip, or microarray, to search for new viruses associated with a wide range of human disease. So far, the chip has been used to search for novel viruses in about 300 cases of respiratory infections and about 50 cases of meningitis, as ...

Argonne researchers confirm lead in Beethoven's illness

...said. "Beethoven saw physician after physician in search of a cure for his physical ailments," said Walsh. In fact, in a letter to a friend, he expressed the wish that after his death, researchers would use his remains to help determine the cause of his illness so that others would not have to suffer as he...
