Researchers track how spores break out of dormant state
...llus spores suggests that evolutionary forces have captured
the mechanical rigidity and resistance of these amyloid self-assembling biomaterials to structure the protective outer spore surface,” Plomp said. When exposed to a solution that triggers germination, nanometer sized etch pits were seen developing...

in the wild and found a wide range of naturally occurring estradiol concentrations in the egg yolks. The researchers then performed experiments in breeding enclosures, each holding one male lizard and three females. The numbers of orange- and yel...
Scientists close in on missing carbon sink
... collaborators set out to test how well the models captured
carbon sinks, focusing in particular on estimates produced by a recent international study into global carbon exchange known as TransCom. They turned to flasks of air collected by research aircraft over various points of the globe for the past 27 yea...

in the Bafgh Protected Area, Yazd Province, in the south-west area of the central Iranian plateau, where they were tranquilized, and fitted with compact GPS collars weighing 350 grams- only 1% of the cheetahs' weight. It is the first time the specie...
Tracking sperm whales and jumbo squid

Ancient amphibians evolved a bite before migrating to dry land
... amphibian skulls reveal how these extinct animals captured
prey, say authors Molly J. Markey and Charles R. Marshall. "Based on experimental data obtained from living fish, we found that the shapes of sutures in the skull roof indicate whether a fish captures its prey by sucking it into the mouth -- like ...

on the bead surface. After the beads are removed from the liquid, optical imaging is used to determine the concentration of a specific protein or virus in the liquid sample based on the number of proteins or viruses attached to the surface of the bea...
Chemical switch triggers critical cell activities
... The goal was to create a freeze-frame image that captured
the fleeting moment when E2 is next to NEDD8, just before it falls off and carries NEDD8 with it. To do that, Schulman's team first had to prevent E2 from binding with NEDD8, so it would not fall away from E1. The investigators used a mutated form of...
