Bee-killing parasite genome sequenced
Agricultural Research Service (ARS) scientists have sequenced the genome of a parasite that can kill honey bees. Nosema ceranae is one of many pathogens suspected of contributing to the current bee population decline, termed colony collapse disorder (CCD). Researchers describe the parasite's genome in a study published June 5 in the open-access journal PLoS Pathogens.

Different Genes Cause Loss Of Body Parts -- Pelvis And Body Armor -- In Similar Fish
New research shows that when two species of stickleback fish evolved and lost their pelvises and body armor, the changes were caused by different genes in each species. That surprised researchers, who expected the same genes would control the same changes in both related fish. The findings shed new light on how evolution produces diversity in nature, and on the evolution of limb loss.

Decellularised Hybrid Hearts May Overcome Barriers to Transplantation
Heart transplantation is plagued by difficulties, specifically by lack of organ availability and by the immune rejection once the organ has been implanted. To overcome these issues, researchers at the university of Minnesota in Minneapolis have created hybrid hearts using decellularised heart scaffolding from one rat and populating it with stem cells from another. The idea is fairly simple: take an organ from a human donor or animal (see image), and use a mild detergent to strip away flesh, cells and DNA so that all is left is the inner 'scaffold' of collagen, an 'immunologically inert' protein. Add stem cells from the relevant patient to this naked shell of an organ and they will differentiate into all the cells the organ needs to function without inducing an immune response after transplant, or any new infections.

Studies Predict Rapid Rise in Sea Levels Along U.S. East Coast
Sea levels could rise faster along the U.S. East Coast than in any other densely populated part of the world, new research shows, as changes in ice caps and ocean currents push water toward a shoreline inlaid with cities, resort boardwalks and gem-rare habitats.
