Salmon life stories recorded in strontium
...s become a record of the fish's environment. "The neat thing about it," says Kennedy, "is the chemical information is laid down in the otoliths on a daily basis, and they can be 'read' much like tree rings, but on an even finer scale." Atlantic salmon generally spend two years inland in streams and riv......, while even longer ones are called proteins. "The neat thing is that we got every possible combination of dipeptide, many tripeptides and some tetrapeptides," said Blank, a geochemist. "We saw variations in the ratios of peptides produced depending on the conditions of temperature, pressure and duration ...Sonic Hedgehog shapes the brain
...ositional signal'. "A positional signal is a neat mechanism for creating patterns of different types of cells," said Cliff Ragsdale, Ph.D., assistant professor in neurobiology, pharmacology and physiology at the University of Chicago, and principal investigator in the study. "Target cells respond d...Card tricks and mathematics: Applying the magician's trade to numerical dilemmas
...ys. ``The card trick helps because it`s simple and neat enough that I can do the math completely.`` Of course, a small group of cards is a very small sample compared to the number of atoms in the world. But that is Diaconis`s forte: applying what he learns from a small, defined system to the larger, com...Ancient running reptile was bipedal, say Science researchers
...eisz. "And it gives us a chance to show that some neat things were happening with reptiles in the Paleozoic, long before the appearance of dinosaurs."......vessels to narrow, increasing blood pressure. "The neat part of this study is we're able to show both the effects on high blood pressure as well as on the organs involved in the control of blood pressure," Raizada said. "We have shown that this form of gene therapy not only prevents these animals from dev...Sandia portable chemical sensor system promises new way of detecting underwater explosives
... submerged them and sent divers into collect water neat the test area. They were able to detect concentrations ofthe explosives at distances of more than 40 feet from the source. These initialtests were where the concentration concept was developed. In a test last year near Panama City, Fla., the research......ia of the brain andthe retina of the eye.) "What's neat about our finding is that we discovered our protein is a homologueof ceruloplasmin and that gives us a clue about what our protein does," saidVulpe. "We knew our gene was important, given the iron deficiency anemia themutation caused, but determinin...Professor Will Connect With Students Live From China Dinosaur Site
...osaur dig in Argentina. "One of the really neat things we have seen is that students can offer suggestions to field problems," Hengst said. "In the field, we often have unexpected results and have to be flexible in what can be done, and this generates a flurry of ideas across the Int...Bacterial Protein Structure Hints At Mechanism Of A Class Of Premature Aging Diseases
...nsures that when DNA replicates,it is brought to a neat and accurate finish, and the cell knows that itis time to divide into two," White said. Recently, helicase malfunction has been found responsible for a classof genetic diseases including Werner's syndrome and Cockayne's syndrome, premature agi...
