In this month’s edition of Physics World, professional “science doodler” Perrin Ireland gives her unique take on one of Richard Feynman’s famous lectures, 50 years after it was first delivered.
The doodle is made up of an array of small, colourful, cartoon-like pictures that merge into one big collage representing Feynman’s “The Great Conservation Principles” lecture that he gave at Cornell University in 1964 – one of the first of Feynman’s lectures to be captured on film.
The doodle, which was commissioned as part of Physics World’s special issue on education, includes two spaceships passing each other to illustrate Einstein’s theory of relativity, two gods playing chess as a description of nature, and a child playing with building blocks to illustrate the law of the conservation of energy.
Ireland first adopted the doodle technique while studying for a human biology degree at Brown University and it became so helpful that her coursemates began asking for copies of her creations.
Chicago – The use of the medication citalopram was associated with a reduction in agitation in patients with Alzheimer disease, although at the dosage used in the study, patients experienced mild cognitive and cardiac adverse effects that might limit the practical application of this medication at the dosage of 30 mg per day, according to a study in the February 19 issue of JAMA.
Agitation, which is common in patients with Alzheimer disease, is persistent, difficult to treat, costly, and associated with severe adverse consequences for patients and caregivers. Pharmacologic therapies have proven inadequate and antipsychotic drugs continue to be widely used for this condition despite serious safety concerns, including increased risk of death, and uncertain efficacy, according to background information in the article. Citalopram, an antidepressant drug frequently used in older individuals, has been proposed as an alternative to antipsychotic drugs for agitation and aggression in dementia, yet there is limited evidence for its efficacy and safety.
Experts call for global overhaul of industrial chemical regulations to ensure children are protected from “silent epidemic” of brain disorders
In a Review published in The Lancet Neurology, two of the world’s leading experts on the link between environment and children’s health are sounding the alarm on the dangers of industrial chemicals. They are calling on countries to transform their chemical risk-assessment procedures in order to protect children from everyday toxins that may be causing a global “silent epidemic” of brain development disorders.
