Chordotonal Organs of Insects
Publisher Summary Chordotonal organs are generally found in Insecta and Crustacea. In insects, chordotonal organs occur in great morphological diversity, and are found at nearly every exoskeletal… Expand

The Redshift of the Optical Transient Associated with GRB 010222
The gamma-ray burst (GRB) 010222 is the brightest GRB detected to date by the BeppoSAX satellite. Prompt identification of the associated optical transient (OT) allowed for spectroscopy with the… Expand

Plasticity in the visual system is correlated with a change in lifestyle of solitarious and gregarious locusts.
We demonstrate pronounced differences in the visual system of a polyphenic locust species that can change reversibly between two forms (phases), which vary in morphology and behavior. At low… Expand

Substantial changes in central nervous system neurotransmitters and neuromodulators accompany phase change in the locust
SUMMARY Desert locusts (Schistocerca gregaria) can undergo a profound transformation between solitarious and gregarious forms, which involves widespread changes in behaviour, physiology and… Expand

SLOW-SPEED SUPERNOVAE FROM THE PALOMAR TRANSIENT FACTORY: TWO CHANNELS
Since the discovery of the unusual prototype SN 2002cx, the eponymous class of Type I (hydrogen-poor) supernovae with low ejecta speeds has grown to include approximately two dozen members identified… Expand

Multiwavelength Observations of Short-Timescale Variability in NGC 4151. II. Optical Observations
We present the results of an intensive ground-based spectrophotometric monitoring campaign of the Seyfert galaxy NGC~4151 for a period of over two months, with a typical temporal resolution of one… Expand

Mechanosensory-induced behavioural gregarization in the desert locust Schistocerca gregaria
SUMMARY Desert locusts show an extreme form of phenotypic plasticity, changing between a cryptic solitarious phase and a swarming gregarious phase that differ in many aspects of behaviour, physiology… Expand

Graded limb targeting in an insect is caused by the shift of a single movement pattern.
Grooming responses are movements of a multi-jointed limb that are targeted toward a stimulus site on the body. To be successful, they require a continuous transformation of stimulus location into a… Expand

Spatiotemporal receptive field properties of a looming-sensitive neuron in solitarious and gregarious phases of the desert locust.
Desert locusts (Schistocerca gregaria) can transform reversibly between the swarming gregarious phase and a solitarious phase, which avoids other locusts. This transformation entails dramatic changes… Expand
