Gene controls whether fear is a factor

...in knockout mice can be used as a model of anxiety states of mental disorders with innate and learned fear components," he added. "As a corollary, these animal models could be used to develop new anti-anxiety agents." Together with the team's earlier findings that the amygdala-enriched gene gastrin-releasi...

Small molecule inhibitor of cholera discovered

...y appears in ScienceJust as hurricanes in the Gulf states and Guatemala have raised the risks of cholera outbreaks, researchers at Harvard Medical School have identified a new type of antibiotic against the cholera bacteria. While traditional antibiotics kill bacteria outright by interfering with processes ...

Logging doubles threat to the Amazon, rivaling clear-cutting, study suggests

...ective logging in the five major timber production states of the Brazilian Amazon, the researchers used the new Carnegie Landsat Analysis System. This technology allowed them to delve into each pixel of the image produced by a trio of satellites and determine the percentage of forested and deforested land w...

Mammalian Transcriptome Mapped

...ed to be. The "central dogma" of molecular biology states that DNA genes are transcribed into RNA transcripts that are then translated into proteins. The RNA, from this point of view, is there to take a gene from DNA to protein, the building blocks of our cells that in turn make up our bodies. RNA, which i...

Applying ecological laws to bacteria

...communities. This confirms the ecological law that states that the bigger the area the greater the number of species present. Scientists previously thought that biodiversity at the microbial level, was fundamentally different to that of larger organisms, such as plants and mammals. This discovery implies t...

Discovery that bacterium is phosphate gourmet key clue to what makes it most social of bacteria

Infectious disease expert warns of spread of Rocky Mountain spotted fever

...opkins' home state of Maryland is among the top 10 states for the disease, with at least 79 cases reported in 2004, up from 19 in 2000.) The scientist also reports that the number of people infected with Rocky Mountain spotted fever, which is fatal in up to 10 percent of those who contract it, has peaked f...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

... February, captured this limit in a formula, which states that objects at distances that are smaller than a certain limit cannot be separated in a light microscope. This resolution limit can be largely ascribed to the fact that light cannot be focused to a smaller spot due to diffraction. It seemed impossib...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure

...ntiation and integration may be important at later states of organ repair," the study noted. The Utah team used MSC for several reasons, notably the fact that they can be harvested easily from bone marrow, isolated, grown in culture and genetically engineered. To test that MSC subsequently used in these st...
