Researchers took a close look at bobtail and bottletail squids to establish their evolutionary relationships and the timing of the divergence of different species.

Bobtail and bottletail squids are small marine invertebrates that are easy to collect, reproduce quickly, and can be raised together in large numbers in laboratories, making them useful model animals for research. They’re cephalopods-related to true squid, octopus, and cuttlefish, which are renowned for their intelligence and complex behaviors, but of which scientists still know little about. Now, in a new study, published in Communications Biology, researchers have used genetic techniques to show that bobtail squid and bottletail squid share a relatively recent common ancestor and that major biogeographic events might have shaped the evolu

The magnitude 9.0 earthquake and tsunami that struck Japan in March 2011 and the Thailand Floods of the same year were among the most destructive natural disasters in Natt Leelawat s lifetime.
For Leelawat who began graduate studies at Tokyo Tech as Japan and Thailand reeled from these disasters the year 2011 would mark a turning point in his life and career. What I learned from Tokyo Tech and being in Japan helped me clarify my interests, create new research on disaster risk reduction, and communicate my knowledge to a new generation of engineers and technologists, he says.
