Sunflower speciation highlights roles for transposable elements in evolution

...erived hybrid sunflower species has validated this mode of speciation by documenting novel structural rearrangements in their chromosomes, as well as large-scale increases in nuclear DNA content. The nuclear-genome size differences between the hybrids and their parental taxa occur in spite of the fact tha...

Sweet yet sophisticated: Honey bee genome lends insight into sociality, sensation and sex

Discovery of a molecular mechanism underlying limb architecture

...gious journal Nature, describe how the operational mode of several "architect" genes has been recycled in the course of evolution to enable limb formation. The establishment of the body architecture is genetically controlled and involves a family of "architect" genes called the Hox genes which has been ...

New study has important implications for flu surveillance

...nly viewed as a typical Darwinian process. In this mode of evolution, the virus' main surface protein, hemagglutinin (HA), is thought to continually change to evade human immune response, resulting in new dominant strains that eliminate all competitors in a series of rapid successions. Unexpectedly, howev...

Pearl, President of Wildlife Trust and a co-founder of the CCM noted, "Fully three-quarters of new diseases have an animal origin. By researching the links between wildlife, livestock, and ...

Study identifies glucose 'sensor' that plays dual role in glucose metabolism and fat synthesis

...activates a nuclear receptor, although the precise mode of binding remains unknown. As part of the study, mice were put on exclusive sucrose or D-glucose diets; all diets were devoid of cholesterol to minimize naturally occurring oxysterols. D-glucose and GW3965 (a synthetic LXR activator) induced simil...

New study links western wildfires to Atlantic Ocean surface temperatures

...tion -- periodically shifted from a cool to a warm mode that lasted roughly 60 years each time, said the study authors. Warmer waters in the North Atlantic correspond with episodes of drought and subsequent fires in the West as shown by fire scars in annual tree rings studied by the researchers, said Th...

New antibacterials being developed to tackle MRSA superbug

... of side-effects in patients. Because of the novel mode of action of the new class of compounds, the levels of resistance in the bacterial population should be extremely low if a new drug was to emerge from this programme. "The antibiotic that we are developing is far more selective than those currently ...

Training breathing muscles improves swimming muscles' performance

...les become fatigued, the body switches to survival mode and "steals" blood flow and oxygen away from the locomotor muscles and redirects it to the respiratory muscles to enable the diver to continue breathing. Deprived of oxygen and fuel, the locomotor muscles become fatigued. "Increasing the strength a...

Whitefly spreads emerging plant viruses

Continued research to learn more about the biology and genetics of both the plant viruses and the whitefly is also needed....

Microwave oven can sterilize sponges, scrub pads

...mbiguous: Two minutes of microwaving on full power mode killed or inactivated more than 99 percent of all the living pathogens in the sponges and pads, although the Bacillus cereus spores required four minutes for total inactivation. Bitton said the heat, rather than the microwave radiation, likely is w...
