Deducing the scale of tsunamis from the ’roundness’ of deposited gravel

Posted · Add Comment

Scientists have found a link between the ’roundness’ distribution of tsunami deposits and how far tsunamis reach inland. They sampled the ’roundness’ of gravel from different tsunamis in Koyadori, Japan, and found a common, abrupt change in composition approximately 40% of the ‘inundation distance’ from the shoreline, regardless of tsunami magnitude. Estimates of ancient tsunami […]

Light-matter interaction without interference

Posted · Add Comment

Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences.

Evolution designed by parasites

Posted · Add Comment

A new paper explores an overlooked aspect of the relationship between parasites and their hosts by systematically discussing the ways in which parasitic behavior manipulation may encourage the evolution of mechanisms in the host’s nervous and endocrine systems.
