Nuts About Nudibranchs

sam

Welcome to guest blogger, marine biologist Sam Craven, from Mad As A Marine Biologist.

As a marine biologist and a diver I feel incredibly privileged to have seen many of the delightful examples of life that the most biodiverse ecosystem on our planet, the coral reefs, have to offer, but nothing has kept by attention and enthusiasm as much as the group of shell-less molluscs, the nudibranchs.

“Do Big Viruses Really Make You Sick?”

ajc

Welcome to guest blogger, noted biologist Alan Cann

For most of my research career, I worked on viruses with small genomes, such as poliovirus and HIV. For me, the attraction of these viruses is that it is easier to understand all the interactions that go on within a small genome than with an unfeasibly large genome such as that of a cell.

1905: Einstein’s Annus Mirabilis

ae

Here is an interesting article from “sent2null” written by David Saintloth, regarding Einstein’s uncanny output in 1905. Not exactly biological in origin, but Einstein as a scientist is an inspiration to all.

1905 was a great year for physics, in this year a 24 year old patent examiner in Bern Switzerland published 4 fundamental papers in physics in 4 disparate areas of the field. The topics included special relativity, the relationship between energy and matter, Brownian Motion and the subject of this post, the photo electric effect.

The photo electric effect paper by Einstein was probably the most practical paper next to the brownian motion paper in that it provided an answer to a long standing problem in electromagnetic theory at the time that had stood as an embarrassment to particle physics. This embarrasment was a legacy of the work of James Clerk Maxwell and his fundamental equations of electromagnetism, by using a continuous wave analog to describe the energy of propagating fields Maxwell was able to do the astonishing, he explained the riddle that was the relationship between electricity and magnetism in clear mathematical terms and he was able to show how light must be itself an electromagnetic wave by showing that all such waves are limited by the speed of light “c” or roughly 186,000 miles per second.
