It does happen. I have previously told the story of a respected elder statesman of the Zoology Department at Oxford when I was an undergraduate. For years he had passionately believed, and taught, that the Golgi Apparatus (a microscopic feature of the interior of cells) was not real: an artefact, an illusion. Every…
‘The ancient teachers of this science,’ said he, ‘promised impossibilities and performed nothing. The modern masters promise very little; they know that metals cannot be transmuted, and that the elixir of life is a chimera. But these philosophers, whose hands seem only to dabble in dirt, and their eyes to pore over…
Langmuir is the most convincing lecturer that I have ever heard. I have heard him talk to an audience of chemists when I knew they did not understand more than one-third of what he was saying; but they thought they did. It's very easy to be swept off one's feet by Langmuir. You remember in [Kipling's novel] Kim that…
An entirely new type of nanomaterial developed at Rensselaer Polytechnic Institute could enable the next generation of high-power rechargeable lithium (Li)-ion batteries for electric automobiles, as well as batteries for laptop computers, mobile phones, and other portable devices. The new material, dubbed a…
Past experiments have shown persuasively that exercise spurs the birth of new mitochondria in muscle cells and improves the vigor of the existing organelles. This upsurge in mitochondria, in turn, has been linked not only to improvements in exercise endurance but to increased longevity in animals and reduced risk for…
I am reminded now, as I think about news and fiction, of a demonstration of the difference between noise and melody which I saw and heard in a freshman physics lecture at Cornell University so long ago. (Freshman physics is invariably the most satisfying course offered by any American university.) The professor threw…
A number of years ago, when I was a freshly-appointed instructor, I met, for the first time, a certain eminent historian of science. At the time I could only regard him with tolerant condescension. I was sorry of the man who, it seemed to me, was forced to hover about the edges of science. He was compelled to shiver…
There is a story that once, not long after he came to Berlin, Planck forgot which room had been assigned to him for a lecture and stopped at the entrance office of the university to find out. Please tell me, he asked the elderly man in charge, 'In which room does Professor Planck lecture today?' The old man patted him…
• Motor neurons die, particularly from age 60 onward. This causes connections between muscle fibers to wither — and that, in turn, eventually leads to loss and shrinking of muscle fibers. As a result, muscles get smaller and a person gets weaker, says Sandra Hunter, an associate professor of exercise science at…
I define it loosely as the ability to bounce back from stress. Many scientists view this solely as biological stress. But many of us who care for older patients see adaptive competence as psychologically critical as well. You don't get to be 109 without life hurling a few curveballs at you, and Reichert has had more…
The time has come for widespread recognition of the radical changes in religious beliefs throughout the modern world. The time is past for mere revision of traditional attitudes. Science and economic change have disrupted the old beliefs. Religions the world over are under the necessity of coming to terms with new…

In the tween movie Twilight, heroine Bella discovers that her boyfriend Edward is a vampire by consulting a website with a convenient link to supernatural occurrences in her very own tiny town. The Internet is here collectively written, but perfectly tailored to exactly her individual needs. It is not the wizened…
