Poor Arnold. Should have stuck to being a barbarian.
"The breakup of giant icebergs may have forced minor evolutionary changes in penguins over the past 6,000 years, a new study suggests.
"Japan's whaling fleet has set sail for Antarctic waters where it will make its biggest catch in 20 years. The boats will aim to catch nearly 1,000 whales over the coming months. A global moratorium on commercial whaling has been in place since the 1980s, but Japan describes its programme as "scientific." The hunting is condemned by most conservation groups on the grounds that it is inhumane, unnecessary and may harm fragile wildlife populations. The fleet sailed on Tuesday from Shimonoseki port for the first year of a "research" programme called JARPA-2. It envisages catching up to 935 minke whales and 10 fin whales during the southern hemisphere summer to "...monitor the Antarctic ecosystem, model competition among whale species... elucidate temporal and spatial changes in stock structure and improve the management procedure for the Antarctic minke whale stocks."
JARPA-2 replaces the JARPA-1 programme which took 440 Antarctic minkes each season. In two years' time JARPA-2 will expand to include humpbacks, the favoured species for whale watchers. Critics say this is commercial whaling in disguise, with meat obtained from the hunts sold for food in restaurants and schools. Scientific objectives can be met through non-lethal methods, they say.
"Japan's announcement that it intends to kill more than twice as many minke whales and hunt two new species over the coming years provoked international outrage earlier this year," commented Philippa Brakes, a scientist with the Whale and Dolphin Conservation Society.
"The Japanese whalers know that the eyes of the world are upon them with an intensity that they have not experienced since the moratorium," she told the BBC News website."

I don't known anyone who has tried this. It may be safe, but I am still afraid. It is after all a spirit cactus.But little is known about the long-term effects of hallucinogenic use. Part of the problem is that many users -- such as LSD aficionados -- take a variety of other drugs, so it's hard to tease out the specific effects of psychedelic drugs.
Enter peyote, currently the only hallucinogenic drug legally allowed for use outside research labs (although that may change). Compared with LSD and mushrooms, peyote is a bit obscure, with its use -- at least legally -- limited to the sacramental rites of the Native American Church, which has as many as 300,000 members. Many peyote users don't take other drugs, making them ideal subjects for hallucinogenic research.
Peyote comes from the crowns of a cactus that grows in northern Mexico and parts of Texas. Harvesters cut off the crown, dry it and sell it in "buttons," Halpern said. Generally, users eat the buttons whole or grind them up into a powder that can be mixed into food or brewed into a tea.
When enough peyote is eaten, users enter a hallucinogenic state thanks to its active ingredient, the chemical mescaline. Halpern and colleagues recruited three groups of Navajos -- 61 members of the Native American Church who regularly ate peyote, 36 alcoholics who have been dry for at least two months and 79 people who reported little or no use of alcohol or drugs. The researchers then gave mental-health and cognitive tests to the subjects."
