flightless mosquito breed dengue fever solution

shared by Skeptical Debunker on 22 Feb 10 - Cached

Dengue fever causes severe flulike symptoms and is among the world's most pressing public health issues. There are 50 million to 100 million cases per year, and nearly 40 percent of the global population is at risk. The dengue virus is spread through the bite of infected female Aedes aegypti mosquitoes, and there is no vaccine or treatment. UCI researchers and colleagues from Oxitec Ltd. and the University of Oxford created the new breed. Flightless females are expected to die quickly in the wild, curtailing the number of mosquitoes and reducing - or even eliminating - dengue transmission. Males of the strain can fly but do not bite or convey disease. When genetically altered male mosquitoes mate with wild females and pass on their genes, females of the next generation are unable to fly. Scientists estimate that if released, the new breed could sustainably suppress the native mosquito population in six to nine months. The approach offers a safe, efficient alternative to harmful insecticides.

A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists. Great idea or frankensketter?

Bacteria are often social creatures. Suspended in colonies of varying shapes and sizes, these microbes communicate with their brethren and even other bacterial species - interactions that can sometimes make them more deadly or more resistant to antibiotics. Now, bacterial colonies sculpted into custom shapes by a 3-D printer could be a key to understanding how some antibiotic-resistant infections develop. The new technique uses methods similar to those employed by commercial 3-D printers, which extrude plastic, to create gelatin-based bacterial breeding grounds. These microbial condos can be carved into almost any three-dimensional shape, including pyramids and nested spheres.

More than 6,000 different species living on the sea-floor have been identified so far and more than half of these are unique to the icy continent. A combination of long-term monitoring studies, newly gathered information on the marine life distribution and global ocean warming models, enable the scientists to identify Antarctica's marine "biodiversity hotspots". Researcher Griffiths describes how krill populations (the shrimp-like invertebrates eaten by penguins, whales and seals) are reducing as a result of a decrease in sea-ice cover. A much smaller crustacean (copepods) is dominating the area once occupied by them. This shifts the balance of the food web to favour predators, like jellyfish, that are not eaten by penguins and other Southern Ocean higher predators. Sea-ice reduction is also affecting penguins that breed on the ice.

"We measured the direction of the body axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582 observations) over a two-year period. After complete sampling, we sorted the data according to the geomagnetic conditions prevailing during the respective sampling periods. Relative declination and intensity changes of the MF during the respective dog walks were calculated from daily magnetograms. Directional preferences of dogs under different MF conditions were analyzed and tested by means of circular statistics. Results Dogs preferred to excrete with the body being aligned along the North-south axis under calm MF conditions. This directional behavior was abolished under Unstable MF. The best predictor of the behavioral switch was the rate of change in declination, i.e., polar orientation of the MF. "

Squirrels are charismatic creatures that can bring joy and entertainment as they frolic in our backyards and parks. However, when these furry critters start invading our homes or wreaking havoc in our gardens, they can quickly become a nuisance. Squirrel control becomes particularly challenging as their behavior and habits change with the seasons. In this article, we will explore the unique challenges posed by squirrels at each time of year and discuss effective strategies to keep them at bay. Springtime Strategies: As spring arrives, squirrels become more active and enter the breeding season. They may choose to build nests in attics, crawl spaces, or chimneys to give birth and raise their young. To prevent these unwanted guests, it is crucial to inspect your property for any potential entry points and seal them off. Trim tree branches that hang near your roof, as squirrels can use them as bridges to access your home.
