Stanford University [Video Lecture]: Darwin's Legacy [18 hours]

"Light will be thrown..." With these modest words, Charles Darwin launched a sweeping new theory of life in his epic book, On the Origin of Species (1859). The theory opened eyes and minds around the world to a radical new understanding of the flora and fauna of the planet. Here, Darwin showed for the first time that no supernatural processes are necessary to explain the profusion of living beings on earth, that all organisms past and present are related in a historical branching pattern of descent, and that human beings fall into place quite naturally in the web of all life.

 

Now, 150 years later and 200 years after Darwins birth, we celebrate the amazingly productive vision and reach of his theory. In this Fall Quarter course, we will meet weekly with leading Darwin scholars from around the country to learn about Darwins far-reaching legacy in fields as diverse as anthropology, religion, medicine, psychology, philosophy, literature, and biology. With such a broad reach across the natural sciences, social sciences, and humanities, no wonder the theory of evolution by natural selection has been called the single best idea, ever.

Comprehensive Virology University Class (26 hours of VIDEO lectures)

Virology - Biology W3310 and W4310

 

The basic thesis of the course is that all viruses adopt a common strategy. The strategy is simple:

 

1. Viral genomes are contained in metastable particles.

2. Genomes encode gene products that promote an infectious cycle (mechanisms for genomes to enter cells, replicate, and exit in particles).

3. Infection patterns range from benign to lethal; infections can overcome or co-exist with host defenses.

 

The course will emphasize the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycles, the interactions of viruses with host organisms, and how these lead to disease are presented with examples drawn from a set of representative animal and human viruses, although selected bacterial viruses will be discussed.

The wisdom of birds

The bullfinch is a truly remarkable bird. Its striking colors are reason enough to adore it but, what's more, male bullfinches can be trained to sing any song you like, provided you are willing to sing to it 15 times a day for months! You can learn more about bullfinch songs here.

Video Of Rarely Seen Pelagic Argonaut Octopus Out Of Its Shell

Argonaut is a type of octopus most commonly found in tropical and subtropical seas. Its presence in temperate waters of Southern California indicate that warm water currents from the South are prevalent. Argonauts are pelagic (usually found far offshore in the open ocean) and demonstrate a dramatic sexual dimorphism (male is about one inch long and females up to 18 inches). The male argonaute has one of it's eight arms (the third) highly modified to carry sperm to the female. The modified arm of the male is called a hectocotylus and during mating this arm breaks off and crawls into the female to remain there until the female is ready to fertilize her eggs. When first discovered in the early 1800s the hectocotylus arm was thought to be a parasitic worm and was given the species name of Hectocotylus (therefore the origin of the term hecotocotylus arm of cephalopods).

 

The female argonaut makes a thin, laterally compressed calcareous shell with one chamber that is used as a brood pouch for eggs. The first of the eight arms of the female bears a wide sail-like lobe that is used to secrete and form the shell. The shell looks like an extinct ammonid shell or resembles shells from the extant cephalopod group called nautiluses. Thus, argonautes are commonly referred to as "paper nautiluses", however, they are octopuses and not closely related to nautiluses. Due to their beauty and delicate nature, argonaute shells are highly prized by collectors

 

Argonauts eat plankton like krill, shrimp and pelagic snails. A recent paper describes an argonaut positioned on the top of a jellyfish and eating away the bell to be able to send arms down through the jelly to remove plantonic food in the jelly's stomach.

 

Argonauts are eaten by tuna, billfish and blue sharks

Francis Crick Memorial Conference 2012: Consciousness in Humans and Animals

Francis Crick Memorial Conference 2012: Consciousness in Humans and Animals | Science-Videos | Scoop.it

The First Annual Francis Crick Memorial Conference, focusing on "Consciousness in Humans and Non-Human Animals", aims to provide a purely data-driven perspective on the neural correlates of consciousness. The most advanced quantitative techniques for measuring and monitoring consciousness will be presented, with the topics of focus ranging from exploring the properties of neurons deep in the brainstem, to assessing global cerebral function in comatose patients. Model organisms investigated will span the species spectrum from flies to rodents, humans to birds, elephants to dolphins, and will be approached from the viewpoint of three branches of biology: anatomy, physiology, and behavior. Until animals have their own storytellers, humans will always have the most glorious part of the story, and with this proverbial concept in mind, the symposium will address the notion that humans do not alone possess the neurological faculties that constitute consciousness as it is presently understood.
