LONDON - A long-term international study of wild Atlantic salmon has discovered that large numbers of free-ranging salmon are being killed by parasitic sea lice, the BBC has reported. Sea lice, which attach themselves to salmon and then eat their flesh, blood and tissue, were responsible for up to 40 % of the deaths of young wild salmon at sea.

Sea lice occur naturally. However, as Der Spiegelreports, in the past 30 years the number of wild Atlantic salmon has fallen by 45 %. According to the study, published by the Royal Society for Biological Sciences, intensive farming of salmon, where sea lice are a common problem, is implicated in the increase of deaths of wild salmon from the parasite.

The joint study, which began in 1996, involved 280,000 individual fish. It was carried out by biologists from Scotland, Ireland, Norway, New Zealand, and Canada.

This essential morning drink for millions worldwide was once considered an addictive menace, earning itself a ban on pain of death in the Islamic world.

Colombia's star product: coffee beans.

BOGOTÁ — October 1st is International Coffee Day. Recently it seems as if every day of the calendar year commemorates something — but for Colombia, coffee is indeed special.

For almost a century now we have largely tied our national destiny, culture and image abroad to this drink. Indeed it isn't just Colombia's star product, it became through the course of the 20th century the world's favorite beverage — and the most commonly used drug to boost work output.

Precisely for its stimulating qualities — and for being a mild drug — coffee was not always celebrated, and its history is peppered with the kinds of bans, restrictions and penalties imposed on the 'evil' drugs of today.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
