Utah researchers confirm chromosome may harbor autism gene

.... In fact, the results of the U of U research were surprisingly similar to the Finnish studies, Coon said. "It was remarkable to confirm the Finnish studies," she said. "Our results were so close to their evidence, we thought it was important." Autism is a behavioral disorder that strikes before age 3 and is c...

Health of Acehnese reefs in the wake of the tsunami shows human impacts more harmful

...daman earthquake was occasionally spectacular, but surprisingly limited, particularly when compared to damage from chronic human misuse in the region. Less than 100 days after the tsunami of December 26, 2004, a team of ecologists from James Cook University, the Wildlife Conservation Society-Indonesia Program, ...

How E. coli bacterium generates simplicity from complexity

... has shown that all this genetic complexity yields surprisingly few physiological functions. This is possibly a general principal in many, if not all, species." Palsson and his colleagues at UCSD, postdoctoral fellows Christian L. Barrett and Christopher D. Herring, and Ph.D. candidate Jennifer L. Reed, created ...

'Perception' gene tracked humanity's evolution, scientists say

...tion affected gene expression. The group found a surprisingly large amount of genetic variation among humans within the prodynorphin gene's promoter. They examined prodynorphin genes from Chinese, Papua New Guineans, (Asian) Indians, Ethiopians, Cameroonians, Austrians and Italians. The group also sequenced a...

Genetic defenders protect crops from fungal disease

...e mechanisms operating at the cell wall seem to be surprisingly simple," Somerville said. "This suggests it might be possible to reverse engineer crops like wheat with Arabidopsis PEN genes to help control powdery mildew and other destructive diseases, thus minimizing the need for pesticides." ...

Russian 'surrogate' alcohols are a killer

...f vodka is drunk in Russia, we also found that ? a surprisingly large number of people ? seven percent ? were drinking substances containing alcohol but not meant to be drunk. We then decided to find out what was in these substances." "History has shown us that alcohol plays an important role in life, health an...

MIT researcher finds neuron growth in adult brain

...e plasticity genes or CPGs. Her group found that a surprisingly large number of CPGs encode proteins in charge of structural change. Why are so many of these genes "turned on" in the adult well after the early developmental period of dramatic structural change? The neuroscience community has long thought that ...

Skull study sheds light on dinosaur diversity

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

...ut the existence of life in outer space may have a surprisingly close-to-home answer, according to one University of Houston professor. Understanding how life evolved on Earth is important in obtaining clues as to where else in the universe one might find life and what it might be like, said George E. Fox, a UH ...

Researchers predict infinite genomes

...he eight GBS genomes, the researchers discovered a surprisingly continual stream of diversity. Each GBS strain contained an average of 1806 genes present in every strain (thus constituting the GBS core genome) plus 439 genes absent in one or more strains. Moreover, mathematical modeling showed that unique genes w...

New method shows it is possible to grow bone for grafts within a patient's body

...lleagues took a new approach that has proven to be surprisingly simple. They decided to take advantage of the body's natural wound-healing response and create a special zone on the surface of a healthy bone in hopes that the body would respond by filling the space with new bone. The approach lived up to their hig...

Gov't Creates Gene Database of Normal Human Tissues

...ody. Recently the Human Genome Project revealed a surprisingly low number of human genes (20,000-25,000), and Khan said it had been previously reported that "only a fraction of that, perhaps 10,000 genes, are actively transcribed in normal cell processes." Thus it becomes strategically useful to characterize thi...

Surface temperatures in Greenland increased 20 to 30 degrees Fahrenheit and water temperatures increased 10 to 20 degrees." Schmittner said the impact of the cu...
