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
This week—August 15, to be exact—celebrates the climax of Air Conditioning Appreciation Days, a month-long tribute to the wonderful technology that has made summer heat a little more bearable for millions of people.
For the most part, Buddhists have historically been less concerned with explaining the world than with generating personal peace and enlightenment. However, the emergence of “engaged Buddhism” – especially in the West, has emphasized a powerful commitment to environmental protection based in no small part on a fundamental ecological awareness that lies at the heart of Buddhist thought and practice.
My career began in the 1970s in the field of cancer immunology, a subject, which nowadays is at the forefront of cancer research, holding the promise of delivering new therapies for treating patients suffering from a wide range of cancers. Many scientists working in the field are not readily aware that the very first research papers documenting immunity against cancer were published in 1955 in the British Journal of Cancer by Robert (Bob) Baldwin, working in Nottingham, England.
Until the current epidemic, Ebola was largely regarded as not a Western problem. Although fearsome, Ebola seemed contained to remote corners of Africa, far from major international airports. We are now learning the hard way that Ebola is not—and indeed was never—just someone else’s problem.
It is well known that many of the permanent inhabitants of caves have evolved a bizarre, convergent morphology, including loss of eyes and pigment, elongation and thinning of appendages, and other adaptations to conditions of complete darkness and scarce food.
