Steve Marvanek, Spatial Data Analyst at CSIRO Land and Water, integrated historical wildlife spotlight data, devil monitoring data and geo-referenced reports of diseased devils into a geographical information system (GIS) ...

Largest synthetic gene ever built offers insights into anti-malarial drug resistance

...searchers can tell where a drug resistant parasite comes from depending on the varied mutations in the three different resistance genes, Roepe said. "There are patterns of mutations in these genes that can tell you if the parasite came from Africa, or Asia, or South America, and what drugs it is most likel...

Sun exposure early in life linked to specific skin cancer gene mutation

...cause of melanomas has been a mystery. A new clue comes from scientists at the University of North Carolina at Chapel Hill Schools of Medicine and Public Health. Their research indicates that early life sun exposure, from birth to 20 years old, may specifically increase the risk of melanomas with BRAF gen...

Breakthrough developments in rheumatoid arthritis reported

...lline. Citrulline is formed when a specific enzyme comes in contact with arginine, one of 20 common amino acids in proteins. When one of the enzymes is present, nitrogen is removed from the chemical structure of arginine and it converts into citrulline. Laboratories have developed a test to measure f...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...o be linked to Leber’s congenital amaurosis (LCA), comes at a time of hope for the people born with the disorder. Scientists at Moorfields Eye Hospital, London, recently announced the start of clinical trials for a gene therapy involving injecting genes into the eye of patients with LCA to restore their si...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

... signals, because it enhances trait production but comes at a health price to the animal.” “This study shows that testosterone may not be as costly as previously thought, so long as animals can nutritionally offset the immune detriments of testosterone. They may even experience a net health benefit as a...

Study shows lizard moms dress their children for success

Mothers know best when it comes to dressing their children, at least among side-blotched lizards, a common species in the western United States. Researchers at the University of California, Santa Cruz, have found that female side-blotched lizards are able to induce different color ...

Genetic factors are linked to fever following smallpox vaccination

...he results may have important implications when it comes to the future goal of identifying individuals at risk for fever before they are given a specific vaccination. Crowe writes, “The long-term goal is to determine genetic features that could be determined prior to vaccination, allowing practitioners to...

Penn researchers link cell's protein recycling systems

...le of HDAC6 “That’s where the power of fruit flies comes in,” Taylor explains. “We can use fruit flies to rapidly screen through many genes to find the one we’re interested in. In the process of screening, our attention was drawn to HDAC6 because we already knew that it could bind to ubiquitin-tagged prote...

Exploring the dark matter of the genome

...inactivate them. That's the kind of knowledge that comes from sequencing heterochromatin." Smith uses the metaphor of dark matter to suggest the significance of heterochromatin. "We don't know what holds the galaxies together, and the same is true of the genome. We're pretty good at understanding how i...

Mutating the entire genome

... or so-called “jumping gene” named piggyBac, which comes from a moth. They used piggyBac to insert pieces of loxP DNA randomly into numerous spots on the mouse genome. So scientists easily can breed multiple generations of mice with loxP surrounding various large stretches of DNA. Then the first part o...

Prey not hard-wired to fear predators

... wild places. When the predator-prey relationship comes back into balance, impacts ripple through the system. For example, when wolves returned to the Yellowstone region, they caused a cascade of events including a change in elk distribution, more wariness in moose, and a change in coyote densities. By ...

"When the traffic has passed, the down-trodden ants climb out of the potholes and follow their nest mates home," added Powell. "Broadly, our research demonstrates tha...

Eavesdropping comes naturally to young song sparrows

When it comes to research about how babies learn language, most work has focused on interactions between a parent and an infant, but infants may learn language in part by eavesdropping on conversations between their parents or a sibling, Beecher said. "Do kid...

Resistant HIV quickly hides in infants' cells

...These findings have important implications when it comes to choosing among available treatments. As Persaud summarized, "The initial transmitted drug-resistant virus will likely never be cleared from that infant with currently available treatments. However, it is important to point out that because PIs a...
