“Total body water was determined by deuterium oxide dilution in 17 normal male subjects with a range of 55.9% to 70.2% and an average value of 61.8% of body weight. Eleven normal females ranged from 45.6% to 59.9% with an average of 51.9%, or 9.9% less than the males. These total body water figures have […]
The special WATER issue (vol. 29, no. 2) of the magazine is now out and about. The table of contents and several of the articles are online. As you might guess, it’s full of improbable research about water.
ProPublica gives a detailed report about a little-noticed consequence of the oil spill that led to an Ig Nobel Chemistry Prize. The ProPublica report begins: A Massive Oil Spill Helped One Billionaire Avoid Paying Income Tax for 14 Years After the Deepwater Horizon offshore drilling rig exploded in 2010, environmentalists surveying the damage in the […]
Dr Johan Lindén who is a lecturer at the Faculty of Science, Åbo Akademi University, Finland, has investigated the (famous) upside down glass of water experiment. But with a crucial variation – the card has a hole cut in it. Nevertheless, the water still stays in the glass – providing that the hole is small enough. […]
When it comes to the question of the optimum droplet diameter for deposition on dead flies (in woodland), there aren’t many pertinent research papers. Possibly only one. A 2009 study from R. T. Jarman of Chesterford Park Research Station, UK, recounts attempts, by experiment, to find out. “An experimental laboratory study of the deposition of […]

Ducks can fly. Ducks can swim. And, unusually, they’re pretty good at something in between – viz. hydroplaning (a.k.a. ‘Skeetering’). If you’ve seen them doing it, you might have wondered about the physics (and math(s)) behind it. In which case, you are not alone … “Common eiders (Somateria mollissima) are heavy sea-ducks that spend a […]
“We used six Helzine [sic] soleirolii, commonly known as Baby’s Tears, plants to conduct our experiment. The plants were divided into two groups, A and B. Both groups were placed in the same amount of sunlight and given the same soil. The plants were fed according to florist instructions. However instead of plain tap water, […]
