New research conducted in the UC Santa Barbara lab of Daniel Morse, professor emeritus in the Department of Molecular, Cellular and Developmental Biology (MCDB), demonstrates that the squid’s ability to “tune” its colors is correlated with the presence of specific sequences of reflectins, proteins unique to the light-sensing tissue of cephalopods.

“Our new work into the cellular mechanisms of squid iridescence allows us to refine experiment design for reflectin-based adaptive photonic structures,” DeMartini said. “In the future, this could be very useful for creating synthetic optical materials that — like squid skin — can be tuned.”
Published today in Science Translational Medicine journal, University researchers, working in collaboration with scientists at King’s College London and the Mayo Clinic (USA), describe the previously unproven role of the calcium sensing receptor (CaSR) in causing asthma, a disease which affects 300 million people worldwide.
Rumours of germline modification prove true — and look set to reignite an ethical debate.
When this rate was applied to estimate the TMRCA between two Y chromosomes that encompass the oldest known patrilineal bifurcation between any humans (representing haplogroups A00 and A0, with 75 derived mutational differences in 180 kb of XDG sequence)19, we obtained a maximum-likelihood estimate21 of 239,000 years ago and a 95% CI of 188,000–296,000 years ago (174,000–321,000 years ago when incorporating the 95% CI of our mutation rate).
In 2013, GE introduced a new, superfast scanner called Revolution CT that allowed doctors to routinely obtain clear images of the beating heart, lungs, liver and other organs.
Seung has also become the leading proponent of a plan, which he described in a 2012 book, to create a wiring diagram of all 100 trillion connections between the neurons of the human brain, an unimaginably vast and complex network known as the connectome.
The deep ocean is far deeper than a person can dive to or fish from, but that doesn’t mean that the things down there are of no consequence to society.
