Energy localisation and frequency analysis in the locust ear [PDF]

open access: yes, 2013
Animal ears are exquisitely adapted to capture sound energy and perform signal analysis. Studying the ear of the locust, we show how frequency signal analysis can be performed solely by using the structural features of the tympanum.

Probing and Tuning Strain‐Localized Exciton Emission in 2D Material Bubbles at Room Temperature

open access: yesAdvanced Materials, EarlyView.
This work provides an approach: 1) to directly visualize the associated exciton properties, revealing an intrinsic emission wavelength shift, and 2) actively modify local strain, enabling further exciton emission tuning. These findings provide direct insights into the strain‐localized emission dynamics in bubbles and establish a robust framework for ...

Programmable Continuous Electrowetting of Liquid Metal for Reconfigurable Electronics

open access: yesAdvanced Materials, EarlyView.
This work introduces a programmable continuous electrowetting (CEW) approach for the dynamic manipulation of liquid metal (LM), enabling directional control via electrochemical modulation. By leveraging laser‐induced graphene (LIG) substrates, a wide range of utilities is demonstrated, including fluidic “valves,” logic gates, and reconfigurable ...

Comment: Food web interactions and biomanipulation in Australian reservoirs [PDF]

open access: yes, 1997
The authors have been studying the control of phytoplankton biomass in several Australian reservoirs. To manipulate fish communities in order to reduce phytoplankton biomass, one needs a thorough understanding of processes in the plankton-associated food

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Electrocortical effects of MDMA are potentiated by acoustic stimulation in rats

open access: yesBMC Neuroscience, 2006
Background 3,4-Methylenedioxymethamphetamine (MDMA; ecstasy) is known for its toxicological, psychopathological and abuse potential. Some environmental conditions, e.g.

The alpha1 subunit of the GABA(A) receptor modulates fear learning and plasticity in the lateral amygdala. [PDF]

open access: yes, 2009
Synaptic plasticity in the amygdala is essential for emotional learning. Fear conditioning, for example, depends on changes in excitatory transmission that occur following NMDA receptor activation and AMPA receptor modification in this region.
