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.
Biomechanics is the study of how animals move. It’s a very broad field, including concepts such as how muscles are used, and even how the timing of respiration is associated with moving. Biomechanics can date its beginnings back to the 1600s, when Giovanni Alfonso Borelli first began investigating animal movements. More detailed analyses by pioneers such as Etienne Jules Marey and Eadweard Muybridge, in around the late 1800s started examining the individual frames of videos of moving animals.
Time is running short. When the IPCC published its first scientific report in 1990 on the possibility of human-caused global warming, the atmospheric concentration of carbon dioxide (CO2) was 354 ppm. It is now 397 ppm and rising. In spite of Kyoto, Copenhagen, Cancun, Durban, and Doha, atmospheric CO2 continues its inexorable upward path.
It pays to be nice. One of the most absolutely, emphatically wrong hypotheses about the oceans was coined by one of the most carefree and amiable people in nineteenth century science. It should have sunk his reputation without trace. Yet, it did not.
It is likely that most ecologists have their own stories regarding the annual meetings of the Ecological Society of America (ESA), the world’s largest organization of professional ecologists. Some revere it, whereas others may criticize it. There is, however, truth in numbers—growth in attendance has been seemingly exponential since my first meeting in the early 1980’s.
What does it mean for a woman to “feel sexy”? In our current consumer culture, the idea of achieving sexiness is all-pervasive: an expectation of contemporary femininity, wrapped up in objects ranging from underwear, shoes, sex toys, and erotic novels. Particular celebrities and “sex symbol” icons, ranging throughout the decades, are said to embody it…
