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…
The past couple of years have seen the celebration of a number of key developments in the history of physics. In 1913 Niels Bohr, perhaps the second most famous physicist of the 20th century after Einstein, published is iconic theory of the atom.
Lipids (fats and oils) have historically been thought to elevate weight and blood cholesterol and have therefore been considered to have a negative influence on the body. Foods such as full-fat milk and cheese have been avoided by many consumers for this reason. This attitude has been changing in recent years.
Social media and other technologies have changed how we communicate. Consider how we coordinate events and contact our friends and family members today, versus how we did it 20 or 30 years ago. Today, we often text, email or communicate through social media more frequently than we phone or get together in person.
At the end of last year, Eli Lilly’s mega-blockbuster antidepressant Cymbalta went off patent. And Cymbalta’s generic version, known as duloxetine, rushes in the market and drives down the price, making it more affordable.
Now that the Internet has been with us for over 25 years, what are we to make of all the concerns about how this new medium is affecting us, especially the young digital natives who know more about how to maneuver in this space than most adults.
Someone asked me at a recent book talk why I chose to write about hope and children in poverty. They asked whether it was frivolous to write about such a topic at a time when children are experiencing the challenges associated with poverty and economic disadvantage at high rates.

That any person could become an expert in something if they simply spend about 3 hours per day for ten years is an appealing concept. This idea, first championed by Ericsson and brought to prominence by Gladwell, has now taken root in the popular media. It attempts to discuss these differences in terms of the environment. The idea is that practice with the purpose of constantly gathering feedback and improving can lead any person to become an expert.

Benign paroxysmal positional vertigo (BPPV) is a very frequent cause of harmless but unpleasant vertigo and dizziness complaints. It is caused by dislodged otoconia floating into the semicircular canals, which measure angular accelerations of the head and initiate corrective eye movements during fast head movements. Otoconia are calcium-carbonate crystals functioning as weights in the miniature acceleration sensors in the inner ear, informing us about gravity and linear accelerations.
