Pain is a universal experience. Throughout time, everyone knows what it feels like to be in pain — whether it’s a scraped knee, toothache, migraine, or heart attack. Although the feeling of pain may remain the same, the ways in which it was described, treated, and interpreted in the 18th and 19th centuries varies greatly from the ways we regard pain today. The below slideshow of images from The Story of Pain by Joanna Burke will take you on a journey of pain throughout history.
The consequences of traumatic brain injury (TBI) are sizable in both human and economic terms. In the USA alone, about 1.7 million new injuries happen annually, making TBI the leading cause of death and disability in people younger than 35 years of age. Survivors usually exhibit lifelong disabilities involving both motor and cognitive domains, leading to an estimated annual cost of $76.5 billion in direct medical services and loss of productivity in the USA.
It was the nest-building season, but after days of long hard work, the sparrows sat in the evening glow, relaxing and chirping away.
Facebook celebrated its tenth anniversary in February. It has over 1.2 billion active users — equating to one user for every seven people worldwide. This social networking phenomenon has not only given our society a new way of sharing information with others; it’s changed the way we think about “liking” and “friending.”
We all know that reading books to our young children is good for them. Teachers, pediatricians, and former First Ladies all tout the value of reading to kids. Contrary to conventional wisdom, however, reading books to children does not help them learn to read.
So far it has been an unusually warm and sunny summer in the United Kingdom, but unfortunately this clement weather has not been matched by the news coverage of world events, which for months has been overcast and stormy as war and tragedy have stalked Europe and the Middle East. But there was a break […]
A large variety of complex systems in ecology, climate science, biomedicine, and engineering have been observed to exhibit so-called tipping points, where the dynamical state of the system abruptly changes. Typical examples are the rapid transition in lakes from clear to turbid conditions or the sudden extinction of species after a slightly change of environmental conditions. Data and models suggest that detectable warning signs may precede some, though clearly not all, of these drastic events. This view is also corroborated by recently developed abstract mathematical theory for systems, where processes evolve at different rates and are subject to internal and/or external stochastic perturbations.
It’s beautiful, our English language — fluid and expressive, colorful and lively. And it’s changeable. New words appear all the time. Consider “selfie” (a noun), “problematical” (an adjective), and “Google” (a noun that turned into verbs.) Now we have two more: “anti-vax” and “anti-vaxxer.”
Egyptian mummies continue to fascinate us due to the remarkable insights they provide into ancient civilizations. Flinders Petrie, the first UK chair in Egyptology did not have the luxury of X-ray techniques in his era of archaeological analysis in the late nineteenth century. However, twentieth century Egyptologists have benefited from Roentgen’s legacy.
At a time when the press and broadcast media are overwhelmed by accounts and images of humankind’s violence and stupidity, the fact that our race survives purely as a consequence of Nature’s consent, may seem irrelevant.
About half a century ago, an MIT professor set up a summer project for students to write a computer programme that can “see” or interpret objects in photographs. Why not!
The anniversaries of conflicts seem to be more likely to capture the public’s attention than any other significant commemorations. When I first began researching the nurses of the First World War in 2004, I was vaguely aware of an increase in media attention.
The discovery of the periodic system of the elements and the associated periodic table is generally attributed to the great Russian chemist Dmitri Mendeleev. Many authors have indulged in the game of debating just how much credit should be attributed to Mendeleev and how much to the other discoverers of this unifying theme of modern chemistry.
Dmitri Mendeleev believed he was a great scientist and indeed he was. He was not actually recognized as such until his periodic table achieved worldwide diffusion and began to appear in textbooks of general chemistry and in other major publications.
How can sacoglossan sea slugs perform photosynthesis – a process usually associated with plants? Kleptoplasty describes a special type of endosymbiosis where a host organism retain photosynthetic organelles from their algal prey. Kleptoplasty is widespread in ciliates and foraminifera; however, within Metazoa animals (animals having the body composed of cells differentiated into tissues and organs, and usually a digestive cavity lined with specialized cells), sacoglossan sea slugs are the only known species to harbour functional plastids.
One of the highest points of the International Congress of Mathematicians, currently underway in Seoul, Korea, has got to be the announcement of the Fields Medal prize winners. The prize is awarded every four years to up to four mathematicians under the age of 40, and is viewed as one of the highest honours a mathematician can receive
