Catch the Preservation Wave

Viruses catch a wave

Viruses catch a wave cientists know from looking at fixed cells that viruses frequently associate with filopodia and microvilli. Using video microscopy, Lehmann et al. (page 317) find that after a virus attaches to the filopodial membrane, it surfs down the plasma membrane toward the cell body. Entry into the cell occurs only after the virus has reached the base of the filopodium. Retroviruses ...

GAAS: Can Silicon Catch the Millimeter Wave?

Transceiver designs implemented in silicon technology are most competitive in design cycle-time and performance versus cost when compared to other technologies. Scaling is driving silicon technology towards gain-bandwidths of 300GHz, enabling circuits operating deep into mm-wave frequency bands (i.e., well above 30 GHz). However, innovations in on-chip passive design and construction currently ...

Left-Right Asymmetry: Nodal Cilia Make and Catch a Wave

Asymmetric fluid flow in the mouse node initiates the development of left-right asymmetry. This flow is generated by motile cilia and is detected by immotile mechanosensory cilia, activating an asymmetric calcium spike.

Catch the wave: prairie dogs assess neighbours' awareness using contagious displays.

The jump-yip display of black-tailed prairie dogs (Cynomys ludovicianus) is contagious, spreading through a prairie dog town as 'the wave' through a stadium. Because contagious communication in primates serves to assess conspecific social awareness, we investigated whether instigators of jump-yip bouts adjusted their behaviour relative to the response of conspecifics recruited to display bouts....
