I have not seen anything like this or even heard about it but it appears that weather conditions can be such that a thick carpet of ice can inexorably march from lakes onto land. It looks like a creeping monster, pushing aside even buildings in its path. It is called an ‘ice shove’ and scientists are familiar with the phenomenon and say it happens on occasion in places like Alaska. [Read more…]
Neuroskeptic looks at the new phenomenon of vigilante science where people are taking it upon themselves to closely examine science research papers for plagiarism, falsification, and fabrication. [Read more…]
In my earlier posts on scientism (see here and here), I said that I never used the word myself since I was not quite sure what it meant and tended to agree with Sean Carroll that the word was being tossed around with too many different meanings that made it not helpful in discourse. One commenter said that the word had a long and illustrious history and that the Oxford English Dictionary had a clear definition. So I went and looked it up. [Read more…]
RadioLab had a good program this week on altruism and how nice behavior could emerge out of natural selection. The first part dealt with the tragic story of George Price, the eccentric but brilliant scientist who developed an equation that showed why someone might sacrifice their life for another. But he personally could not deal with the conclusion that all altruism was not a freely chosen act. [Read more…]
The clip below discusses why it is so disorienting to go into one of those rooms that are just like normal rooms, except that they are tilted. Even being aware of the source of the effect does not prevent people from feeling a strong sense of discomfort, even nausea. [Read more…]
Walt Mossberg has written the personal technology column at the Wall Street Journal for 22 years. In his final column, he lists the top 12 new items that he feels changed the industry. It is interesting to see that it was not that long ago that the things that are all around us and seem to have been around forever were invented, and how quickly those that were similarly ubiquitous before but did not last (Netscape, Palm Pilot) disappeared from our memories.
I used to drive a station wagon and one of its best features, especially useful in winter, was the rear window windshield wipers. They were so useful that I wondered why they were standard equipment only on wagons and hatchbacks and came to the conclusion that this must be because those rear windows were pretty much flat, while the curved and the sloping rear windshields of other cars made it technologically difficult. I am not sure if that is the real reason since it seems like engineers could have overcome that. [Read more…]
The person who voiced the original iPhone Siri has revealed herself as Susan Bennett, although Apple won’t confirm it. But what interested me in the story was how the system was created. [Read more…]
Carl Zimmer has an interesting article on the biology of smell. It is truly remarkable how our noses can detect the presence of a tiny amount of one type of molecule in the vast expanse of other molecules.
He first describes the process by which we register the presence of a smelly molecule. [Read more…]
Major science journals issue science journalists with press releases about papers that they think will make a splash and give them embargoed advance copies of the articles so that journalists can research them and write their articles with the understanding that the articles won’t be published until the journal is released.
