...book Diet for a Small Planet, Frances Moore Lappe argued more than 35 years ago that grain-fed cattle were essentially "reverse protein factories" because they required many more pounds of plant protein to produce a pound of flesh. Now there's a similar dynamic in the global fish farming, or aquaculture, industry - especially as it strains to satisfy consumers' voracious appetite for top-of-the-food chain, carnivorous fish, such as salmon, tuna and shrimp...
...demand has doubled since that time. Here's the catch: It takes a lot of input, in the form of other, lesser fish - also known as "reduction" or "trash" fish - to produce the kind of fish we prefer to eat directly. To create 1 kg (2.2 lbs.) of high-protein fishmeal, which is fed to farmed fish (along with fish oil, which also comes from other fish), it takes 4.5 kg (10 lbs.) of smaller pelagic, or open-ocean, fish. "Aquaculture's current heavy reliance on wild fish for feed carries substantial ecological risks," says Roz Naylor, a leading scholar...
...been enrolling cancer patients in a Phase I clinical study of a most unexpected medication: fat. Their trial puts patients on a so-called ketogenic diet, which eliminates almost all carbohydrates, including sugar, and provides energy only from high-quality plant oils, such as hempseed and linseed oil, and protein from soy and animal products...
...spigot that controls the destiny of millions of people in five countries. Environmental groups estimate that 35% of the silt that's needed to fertilize floodplains down south may be obstructed by the dam - distressing news for a region that depends on the Mekong for 80% of its protein needs and, in the lower river basin, rice production...
...deep end of science is where Jose Varghese likes to be. Part of the pioneering team that in the mid '90s developed the anti-influenza drug Relenza - one of only two drugs known to be effective against avian flu - Varghese is now focusing on an enigmatic protein, amyloid beta, and what he suspects are its toxic effects on the brains of people with Alzheimer's. In the international race to uncover amyloid beta's molecular structure - the crucial first step in finding out how to block its pathological effects - synchrotron X rays are a crucial tool. The molecules...
