Art of the Demo: The Evolution of Insect Images By Joseph Parker

Event: Columbia University Libraries' Data Visualization Week: The Art of Data Visualization
Hosted by: Columbia University's Science and Engineering Library

The forms of biological structures reflect their functions as well as their past evolutionary histories. Yet, for some primeval reason, at every scale the natural world appears beautiful to the human eye. As a consequence, the field of biology is an inherently aesthetic discipline, and central to the discipline’s own evolution has been the continued development of new ways for depicting the intricacies of biological entities. In this talk, I focus on a branch of biology fixated on the very small: entomology. From historical scientific drawings of insects to modern laser confocal microscopy and micro-CT, the arsenal of illustration and visualization methods at the entomologist’s disposal has grown. Details of morphology, patterns of gene expression during embryonic development, and internal structures of fossil insects can be revealed that were unimaginable to the 19th century entomologist.

Asleep at the Wheel: Drowsy Driving and Public Health

source: Harvard University     2016年5月11日
Driving while under the influence of drugs or alcohol has long been established as a public safety hazard. But what about hitting the road while fatigued? An estimated average of 83,000 accidents involving drowsy driving occurred annually between 2005 and 2009, according to the National Highway Traffic Safety Administration (NHTSA), and some estimates are even higher. These accidents cost lives, cause injuries, and damage property. This Forum event explored the risks, impacts and prevention of drowsy driving. Speakers included Arianna Huffington, author of the new book The Sleep Revolution; Mark Rosekind, Head of NHTSA; Charles Czeisler, renowned sleep medicine expert; and Jay Winsten, leader of a large-scale media initiative to draw attention to the perils of distracted driving.
Presented May 10, 2016, in Collaboration with The Huffington Post.

Obesity is an escalating global epidemic. It substantially raises the probability of diseases like diabetes, heart disease, stroke, high blood pressure, and cancer. But what is the distinction between being overweight and being obese? And how does a person become obese? Mia Nacamulli explores obesity.

Jack Cooke: "The Tree Climber's Guide" | Talks at Google

source: Talks at Google      2016年5月13日
We were joined in London by Jack Cooke to discuss his book about exploring London through its canopy - The Tree Climber’s Guide.
Recorded April 2016.
Jack can be found on Twitter at @typecooke and his website is:

Jack's video of trees can be found here:
https://www.youtube.com/watch?v=2HAAB...

About the book:
A wonderful cocktail of engaging writing, beautiful illustration and heartfelt appreciation for the natural world. An essential oddity for any book collection.
‘I agree with so much of what Jack has to say - about trees, risk, being more child-like, and seeking out pockets of peace even in our cities.’ Alastair Humphreys
In this charming, witty and exquisitely illustrated companion, Jack Cooke explores the city through its canopy; teetering on the edge of an oak’s branches, scurrying up a Scots pine, spying views from the treetops that few have ever had the chance to see. He takes us through the parks, over the canals and rivers and into secret gardens on his journey sometimes only ten foot above the street.
Part guidebook, part meditation on the consolations of nature, The Tree Climber’s Guide is as uniquely odd, alluring and motley as the trees themselves. It is a journey into the tangle of bark and branches that surround us all and a welcome reminder that the best things in life are free – they just sometimes require a step in the right direction.
