The Gonzo Scientist
In this installment, our intrepid Gonzo Scientist slips the surly bonds of Earth (well, sort of) and learns that a space suit may not be the best choice of attire when attempting to sneak uninvited into a scientific meeting.
Fungi with long filaments surrounding their nematode prey are preserved in Cretaceous amber, indicating that fungi have evolved trapping structures multiple times.
Mutations commonly associated with cancer result in disrupted interactions between the domains of a growth-related lipid kinase and alter its regulation or activity.
An optical pulse sequence can be stored in an optical fiber as a sound wave that then can be retrieved after a controllable time interval.
Spatially sensitive spectroscopy reveals that as vanadium oxide transitions to a metal, metal nanopuddles form in which conduction is different than in the bulk metal phase.
Controlled reduction of a magnesium compound coordinated by bulky nitrogen-based ligands yields the previously elusive +1 oxidation state of the element.
Experiments reveal how gold-oxide catalysts produce hydrogen: The oxide dissociates water while the gold absorbs CO and the reaction proceeds along their interface.
Flume experiments show that mudstones and their internal layers, thought to reflect small particles settling in still water, can form in flowing water when particles clump together.
Simulation of a major tropical climate oscillation shows that an interplay between atmospheric disturbances traveling in opposite directions yields its eastward propagation.
A major atmospheric oscillation not only affects the surface of the tropical Indian and western Pacific oceans but also initiates large internal waves to depths of 1500 meters.
The success of the invasive whitefly in China and Australia is the result of reproductive suppression of native populations by the invader.
Pink salmon farms in western Canada are breeding grounds for sea lice, which are escaping into nearby waters and decimating the local wild salmon populations.
Amphibians that must travel to water in order to breed are particularly threatened by landscape disruption, explaining the severe decline in amphibians with aquatic larvae.
A serine within a repetitive element of mammalian RNA polymerase II is phosphorylated to modulate transcription and binding of factors for noncoding small nuclear RNAs.
A widespread group of marine Archaea efficiently fix carbon dioxide via a newly described, 16-step metabolic cycle, potentially important for the global carbon budget.
A nuclear receptor is a heme sensor that coordinates circadian and metabolic functions by controlling the expression of a major clock component and the gene for generating sugar.
In Arabidopsis, cyclic ADP ribose, a cytoplasmic signaling molecule, modulates the circadian clock, driving periodic Ca2+ release and boosting robustness of the oscillator.
