New Study Finds Axons May Resemble 'Strings of Beads' Instead of Smooth Lines
A recent study challenges the traditional view of axons as smooth, cylindrical fibres, revealing they may actually resemble "strings of beads" or nanoscopic varicosities. Conducted by researchers at Johns Hopkins University using a high-pressure freezing imaging method, the discovery showed rotund blobs connected by thin tubes within axons. These s...

Drought-Stressed Plants Emit Sounds That Guide Moth Egg-Laying Choices
A study published on November 14 via bioRxiv highlights that drought-stressed plants emit ultrasonic sounds influencing moth egg-laying decisions. Experiments showed Egyptian cotton leafworm moths avoided dehydrated plants and preferred healthier ones. Even laboratory-raised moths demonstrated this innate behaviour. The findings suggest potential f...

Arecibo Observatory Data Helps SETI Uncover Secrets of Pulsar Signals and Cosmic Distortions
Data from the now-collapsed Arecibo Observatory continues to drive major discoveries in space science. Sofia Sheikh and her team from the SETI Institute utilised archived data to investigate the signals of pulsars—dense neutron stars emitting radiation like cosmic lighthouses. Their study focused on how these signals are distorted by interstellar...
