Dino "gap" support the sudden crash
Corner of dinosaurs in Montana supports the idea that the dinos died after critical Thud. Fossils have been excluded under these three meters of the ground under substantially what triggered the k–t, marking the end of the remains of the days of the dinosaurs. The alleged lack of fossils of dinosaurs three metres below (and older) than the border has been invoked in arguments that dinosaurs died gradually, possibly from the climate before the asteroid walloped the Earth. Analysis of pollen and other evidence, however, put the Horn 1.11 metres below, supporting the idea that dinos mounted on up to the abrupt events on the frontier, Tyler Lyson Yale and colleagues report in the coming of biology letters. — Susan Milius

Slacker cats fish
Personality or consistent behavioral types, can have many of the fish typographical and assist in the home. In the debates on the evolution of behavior useful theories predict that relatives should benefit from the mutual assistance of States. However, experience with freshwater fish, the tendencies of the individual personality, for example, aggressiveness and reluctance to take risks were better weight than kinship with that of fish increased the height of help defense or maintenance of a shared territory. The arguments of altruism necessary to take account of differences in behavior, researchers in Europe to cope with the coming of the animal behavior. — Susan Milius

Doubt, decrease in bee and Iridovirus
One suggested that the cause of the sudden Collapse colonies in North America managed to get support to new research. Last year, researchers suggested that unidentified Iridovirus may combine with well known parasite Nosema as deadly combo for honeybees. Now researchers from Columbia University and Penn State University in University Park were analysed colonies both healthy and collapsing and have also been examined samples of older bees. Showed a lack of connection with Colony Collapse Disorder Iridovirus and up in each of these cases, the team reports online on June 30, in PLoS ONE. — Susan Milius

Rethinking carnivorous traps
A key aspect of the potential killing of Nepenthes pitcher plants was undervalued, say researchers in France. Biologists long described carnivorous pitcher-shaped pointer leaves as pitfall traps which lure insects down slippery, covered with wax, which does not operate with the study of one species of Nepenthes, but identified the liquid pools in pitchers as insect traps enough viscosity in its own right. Now new analysis 23 types of pitchers will find other cases of hazardous liquids and suggests that plants can make tradeoffs in how much they invest in the walls of waxy, perfect for catching ants — vs. the gooey liquid that traps flies better, new Phytologist, report scientists. — Susan Milius
