Health: “Understanding Parkinson’s Disease” (Nature Videos)
Parkinson’s disease is a neurological condition that affects the brain and other parts of the nervous system. The gradual loss of nerve cells leads to a suite of characteristic motor and non-motor symptoms.
What causes these cells to die and how the pathology develops in the nervous system are not yet clear but multiple lines of investigation are being pursued to answer these questions. In this animation, we explore some of the latest in Parkinson’s disease research.

Studies: “Blood-Based ‘Liquid Health Check’ Beats Traditional Predictors of Multiple Disease Risks” (Nature)
From a Genetic Engineering & Biotechnology News release:
“This proof of concept study demonstrates a new paradigm that measurement of blood proteins can accurately deliver health information that spans across numerous medical specialties and that should be actionable for patients and their healthcare providers,” said Peter Ganz, MD, co-leader of this study and the Maurice Eliaser distinguished professor of medicine at UCSF and director of the Center of Excellence in Vascular Research at Zuckerberg San Francisco General Hospital and Trauma Center.
Specific patterns of protein levels in our blood could be used to provide a comprehensive “liquid health check” that gives a snapshot of health and potentially an indication of the likelihood that we will develop certain diseases or health risk factors in the future, according to research by scientists in the U.S. and U.K. working with SomaLogic. The results of their proof-of-concept study involving more than 16,000 participants, and published in Nature Medicine, showed that while the accuracy of models based on specific protein expression patterns varied, they were all either better predictors than models based on traditional risk factors, or would constitute more convenient and less expensive alternatives to traditional testing.

Top New Nature Books: “Turning The Boat For Home” By Richard Mabey
From a Cotswold Life online interview/review:
“I suppose I started off with a fairly literal view of the world,” he says. “But, quite early on, it became clear to me that there was much more going on than simply the picture I was seeing; that the natural world had an agenda of its own; that it was going to live out life, regardless of how we viewed it and how we used it; and, indeed, regardless of the fancy metaphors that we used.”
Oh my goodness. Where to begin?
I could start with the ‘Praying Beech’ – a tree whose (‘whose’? The human possessive feels simultaneously wrong and yet just right) two branch stubs clasped each other like hands. Once, when the rain fell in an apocalyptic burst, Richard Mabey watched its bark melt in front of his eyes. It was, of course, no stranger to extremes of weather: one summer past, the tree had been split by lightning, bees hunkering down in its newly-created hollows. Sometime later, a storm had toppled it, leaving fungi free to colonise its delicious surfaces: knobbly coral spots; dead man’s fingers rising corpse-like from the tree’s own rot; white porcelain tufts, like Royal Worcester plates awaiting a delicate slice of egg-yellow sponge.
