Rascal rabbits Evidence of animals sensing where people are looking and what they’re seeing is interesting yet hardly new (“Monkey See, Monkey Think: Grape thefts instigate debate on primate’s mind,” SN: 3/12/05, p. 163). For years, I have observed that wild rabbits will remain motionless as long as I stare in their direction. But as […]

Since the hypoxia described in this article isn’t caused directly by the fertilizer, but by the subsequent algae blooms, then perhaps an effective solution is to combat the algae. It might even be profitable to harvest the algae. If the fishing industry is capable of depleting the seas of species that we want there, then […]

Complex issue When cyanobacteria and plants transfer electrons photosynthetically, light is absorbed not by their photosynthetic proteins but by chlorophylls (“Protein Power: Solar cell produces electricity from spinach and bacterial proteins,” SN: 6/5/04, p. 355: Protein Power: Solar cell produces electricity from spinach and bacterial proteins). Some of these proteins indeed participate in electron flow, […]

In spite of them? Evidently, death waits for no one, except in Belgium (“Death Waits for No One: Deferred demises take a couple of hits,” SN: 6/5/04, p. 356: Death Waits for No One: Deferred demises take a couple of hits). Around 40 years ago, Belgian doctors went on strike for 3 months. If I […]
