Wisconsin scientists find a way to make human collagen in the lab

...opens a door to producing a material that can have broad use in medicine and replace the animal products that are now used but that can also harbor pathogens or spark undesirable immune responses. What's more, the new work may also lay the foundation for applications in nanotechnology -- such as microscopi...

Newly discovered protein kills anthrax bacteria by exploding their cell walls

...n't know of any other lytic enzyme that has such a broad range of activity." In addition, PlyPH, like PlyG, is highly specific in terms of the types of bacteria it affects. When Fischetti and colleagues added PlyPH to different bacterial species, only the anthrax bacteria were killed. This is a great bene...

Attention shoppers: Researchers find neurons that encode the value of different goods

...nge on the left, or vice versa. "This result has broad implications for possible psychological models of economic choice," says Padoa-Schioppa. "It suggests that economic choice is, at its essence, a choice between goods as opposed to a choice between actions--such as reaching to the right to take the ap...

Manipulating single cell receptor alters animal behavior

..., can provoke different behaviors in mammals. The broad implication of the findings may alter the way behavioral neuroscientists think about sub-cellular underpinnings of mammalian behavior, according to the researchers. The study, "Divergent Behavioral Roles of Angiotensin Receptor Intracellular Signal...

New nano-canary in the nanotoxicology coalmine: The body itself

...sponse," said Weber. FTIR spectroscopy measures a broad spectrum of chemical bonds and will provide information that is complementary to genomic and proteomic approaches. FTIR spectra are captured in minutes in live cell studies, offering a tool to rapidly detect whether nanoparticles are biologically ac...

Experimental TB drug effective against resistant and latent mycobacterium tuberculosis

...cobacteria that cause the disease rather than at a broad array of non-pathogenic organisms, which merely enhances the emergence of drug- resistant strains. No resistance has been encountered to FAS20013 in clinical isolates,. The short-term killing power of FAS20013 is greater than currently used drugs; fo...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

...es. These species, which typically forage across a broad area of the North Pacific Ocean, showed little change in their movement patterns in 2004 and 2005. As platforms for ocean sensors, northern elephant seals and California sea lions can provide complementary information because of their different forag...

With broad alliances of support from indigenous groups, smallholder farmers, environmentalists, and government, it is possible to create protected areas in the active frontier of the Amazon and elsewhere. This is good news for governments and environmental gro...

Birth defects: 8 million annually worldwide

..." says Prof. Modell. The data, however, do permit broad comparison of specific birth defects across regions and among countries of different income level, Dr. Howson says. "Such comparisons show that the highest birth defects prevalence is found among the world's poorest countries, whereas many of the lo...

Yale scientists decipher 'wiring pattern' of cell signaling networks

...ulation and integration of biological networks has broad applications for basic science and clinical research," said Snyder. "Biological networks determine the development and function of organisms from the single-celled yeast to man; aberrations in those networks signal disease." Biological networks are...

Scientists develop protein-sequence analysis tool
