| Ebola's secret weapon revealed Posted: 02 May 2013 04:22 PM PDT Researchers have discovered the mechanism behind one of the Ebola virus' most dangerous attributes: its ability to disarm the adaptive immune system.  |
| Lava erupting on sea floor linked to deep-carbon cycle Posted: 02 May 2013 04:22 PM PDT Scientists have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth.  |
| Tick-borne lone star virus identified through new super-fast gene sequencing Posted: 02 May 2013 03:52 PM PDT The tick-borne Lone Star virus has been conclusively identified as part of a family of other tick-borne viruses called bunyaviruses, which often cause fever, respiratory problems and bleeding, according to new research.  |
| Cell biology: Active transporters are universally leaky Posted: 02 May 2013 11:27 AM PDT Biochemists found that as active transporters in cell membranes undergo conformational changes to allow their main substrates to pass through through, small molecules like water slip through as well.  |
| Scientists revolutionize creation of genetically altered mice to model human disease Posted: 02 May 2013 10:17 AM PDT Scientists have efficiently created mouse models with multiple gene mutations in a matter of weeks. Because the method does not require embryonic stem cells, the approach also could allow any animal to become a model organism.  |
| Madagascar tortoise trafficking rages out of control Posted: 02 May 2013 08:55 AM PDT Illegal trafficking of two critically endangered tortoise species from Madagascar has reached epidemic proportions.  |
| 3-D simulation shows how form of complex organs evolves by natural selection Posted: 02 May 2013 07:45 AM PDT Researchers have developed the first three-dimensional simulation of the evolution of morphology by integrating the mechanisms of genetic regulation that take place during embryo development. The study highlights the real complexity of the genetic interactions that lead to adult organisms' phenotypes (physical forms), helps to explain how natural selection influences body form and leads towards much more realistic virtual experiments on evolution.  |
| Primate hibernation more common than previously thought Posted: 02 May 2013 06:47 AM PDT Until recently, the only primate known to hibernate as a survival strategy was a creature called the western fat-tailed dwarf lemur, a tropical tree-dweller from the African island of Madagascar. But it turns out this hibernating lemur isn't alone.  |
| Finding Nematostella: Ancient sea creature shines new light on how animals build an appendage Posted: 02 May 2013 06:35 AM PDT A study of tentacle formation in a sea anemone shows how epithelial cells form elongated structures and puts the spotlight on a new model organism.  |
| New imaging technique to visualize bio-metals and molecules simultaneously Posted: 02 May 2013 05:17 AM PDT Metal elements and molecules interact in the body but visualizing them together has always been a challenge. Researchers have now developed a new molecular imaging technology that enables them to visualize bio-metals and bio-molecules simultaneously in a live mouse. This new technology will enable researchers to study the complex interactions between metal elements and molecules in living organisms.  |
