...study, which was conducted on mice, is part of a hot new area of research called epigenetics, which explores how experiences and environmental exposures affect genes. "This is a major step in understanding the development of cocaine addiction and a first step toward generating ideas for how we might use epigenetic regulation to modulate the development of addiction," says Peter Kalivas, professor of neuroscience at the Medical University of South Carolina, who was not associated with the study.

...Government opponents claim that Saleh's use of state resources to bolster his circle of supporters has left the rest of the country to rot. But not all of Yemen's problems are Saleh's doing. The country faces a severe water shortage, in large part because of the national addiction to khat, a shrub whose young leaves contain a compound with effects similar to those of amphetamines. (The crop accounts for roughly a third of the country's water usage.) Moreover, Yemen's production of oil - which constitutes 90% of its exports - is limited and could...

About two-thirds of the country is in the hands of either separatist groups or local tribes, some of which have a habit of kidnapping foreign tourists to use as bargaining chips with the central government. Economic and developmental issues - Yemen's most volatile regions are among those hardest hit by drought and government neglect - are at the heart of most of those conflicts, especially the war between the government and Shi'ite rebels, known as Houthis, that...
...Though an international moratorium on commercial whaling has been in place since 1986, Japanese whalers use a provision - some say a loophole - that allows whales to be killed for research. This summer in the southern hemisphere, Japan aims to cull 985 whales for scientific purposes, according to a Reuters report. Though their boats are emblazoned with the word "Research," much of their catch ends up on the plates of Japanese consumers, not in labs. Japan's ICR says that the income from whale-meat sales funds scientific research and that international law mandates that it not waste the meat...
...commemoration of the 1979 revolution that begins on Feb. 1, marking the day the revolutionary leader Ayatullah Ruhollah Khomeini returned to Iran from 14 years in exile. The celebration is the most important political holiday of the year in Iran. It is likely the opposition will use the occasion to make another statement...
