Scientists describe the world's smallest, lightest fish
...opment, but they may have the ability to evolve as fast as their environment changes." Philip Hastings, the curator of the Scripps Marine Vertebrates Collection, says the identification of the stout infantfish is another demonstration that scientists do not yet possess a complete inventory of marine anima...90 million year old dino tracks found on resort island
.... This information is important for estimating how fast the dinosaurs were walking and how big they were by measuring the distance between their footprints. Originally, Caldwell and Radovcic went to the island of Hvar to search forfossils of marine lizards and snakes. Fossils of these animals were first...Rutgers chemist uses NMR to elucidate protein-DNA interaction
... of how proteins and DNA find each other in a very fast and accurate way. It provides us with a classical model for understanding protein-DNA interaction and offers valuable information about how transcription can be modulated at the gene level." ...Carnivore species are predicted to be at increased extinction risk from human population growth
...ecies with long gestation periods can't repopulate fast enough and become endangered. Based on projected human population growth, the researchers predict that many carnivore species will join the list of endangered species list by 2030. Most of these species live in Africa, where human populations are gro...When sun's too strong, plankton make clouds

...Open Access to research literature achieves impact fast and makes quality articles much more widely visible. Arthritis Research & Therapy jumped from 3.44 to 5.03, propelling it to rank second in the rheumatology field in only its 6th year of publication. Breast Cancer Research also increased its impact f...Survival of the fastest: scientists 'selectively breed' winning Formula One cars

The breakthrough came when a collaborator in the physic...Researchers establish first molecular link between eating and aging
... the bloodstream, fat cells also tell the body how fast to age. "Conversely, fewer fat cells tell the body that it's time to hunker down for survival. This means that evolutionarily speaking, fat plays a very important role," he said. We know already fat or lack of it has vast implications in the live......Ohio State will discuss surprising developments in fast rotating Bose gases (G2 2).
