Here is what I am reading today:
“”The Squid and its Giant Nerve Fiber” was filmed in the 1970s at Plymouth Marine Laboratory in England. This is the laboratory where Hodgkin and Huxley conducted experiments on the squid giant axon in the 1940s. Their experiments unraveled the mechanism of the action potential, and led to a Nobel Prize. Long out of print, the film is an historically important record of the voltage-clamp technique as developed by Hodgkin and Huxley, as well as an interesting glimpse at how the experiments were done. QuickTime video excerpts from the film are presented here: Dissection and anatomy (J.Z. Young); Removing the mantle nerves (H. Meves); Cleaning and cannulating a giant fiber; Voltage clamping (P.F. Baker & A.L. Hodgkin); Injection & perfusion (R.D. Keynes).”
“That’s what researchers found when they played recordings of people for elephants in Kenya. Scientists say this is an advanced thinking skill that other animals haven’t shown. It lets elephants figure out who is a threat and who isn’t.
The result shows that while humans are studying elephants, the clever animals are also studying people and drawing on their famed powers of memory, said study author Karen McComb.”
“Semir Zeki is a well-known vision researcher who has made notable contributions to our understanding of color vision in primates. Since his original mapping studies, other researchers have made a few anatomical discoveries—in particular, the so-called color “globs,” which are millimeter-sized nodules in the part of the parvocellular (small cell) stream known as the V4 complex. Today Zeki has moved on to higher things and has just published a paper on the neural correlate of the experience of mathematical beauty.That may be an appropriate topic for a researcher at the apex of their career, but it seems we still have much to learn about the more mundane experience of color.”
“Every March, BAW unites the efforts of partner organizations worldwide in a celebration of the brain for people of all ages. Activities are limited only by the organizers’ imaginations and include open days at neuroscience labs; exhibitions about the brain; lectures on brain-related topics; social media campaigns; displays at libraries and community centers; classroom workshops; and more. Interested in getting involved? Visit Become a Partner for more information.”
“The paper, aptly titled “Blurred Lines? Sexual Aggression and Barroom Culture,” after the summer hit by Robin Thicke Kathryn Graham, was published earlier this week in the journal Alcoholism: Clinical & Experimental Research. “Its not a blurred line, its a pretty easy line,” says Kathryn Graham, senior scientist at the Center for Addiction and Mental Health in Toronto and co-author of the paper. “The whole culture that thinks blurred lines is some kind of truth or inevitability, from our data, is a little bit astray.””
“Professor Karen Pine, a psychologist from the University of Hertfordshire and co-founder of Do Something Different, said: “Practising these habits really can boost our happiness. It’s great to see so many people regularly doing things to help others — and when we make others happy we tend to feel good ourselves too. This survey shows that practising self-acceptance is one thing that could make the biggest difference to many people’s happiness. Exercise is also known to lift mood so if people want a simple, daily way to fee happier they should get into the habit of being more physically active too.”"
