...would have a budget of up to $200 million, funded by contributions from the private sector (hotels and airlines, for instance) and a new $10 fee that would be paid by any entering foreign visitor who does not require an entry visa. The latter element has proven controversial - especially to the mostly European travelers who would have to contend with those extra costs. Ambassador John Bruton, head of the European Commission delegation to the United States, called the potential levy "discriminatory" in a September statement, and warned that it could become "a step backward in our joint endeavor toward transatlantic...
...Diseases have been stamped out before. The last case of naturally occurring smallpox was in 1977, after the disease killed about 300 million people earlier in the century. But finding a cure for malaria has proven more elusive. Artemisinin, which is still considered the most effective malaria treatment today, is derived from sweet wormwood, an herb native to Asia. It's been used to fight the disease in China for more than 2,000 years, but it wasn't until 1965 that the cure was isolated and purified by the Chinese military after its soldiers started falling ill during...
...artemisinin has been taken in Southeast Asia for more than 30 years - more than two decades longer than in most of the world - which has given the parasite more time to adapt. Getting people to take the right treatment has also proven to be a public-health challenge. As a fast-acting drug that typically clears out the parasite in less than 72 hours but doesn't remain in the body, artemisinin is prescribed with a slower partner drug to clean out any straggler parasites that might have developed resistance. Taking a partner drug with artemisinin, called combination therapy...
...good news is that while taking CO2 out of our energy cycle has proven very difficult - especially in poorer developing nations - black-carbon emissions should be easier to curb. Reducing deforestation will help - the burning of tropical rain forests is a big contributor to the black-carbon load. Next, diesel filters in cars can be upgraded, and biomass-burning stoves can be exchanged for technology that uses solar power or natural gas. These changes will cost money, but they should be cheaper than decarbonization. And cutting back on black carbon will also pay immediate health dividends, with less air pollution...
Hallucinogens, on the other hand, have been proven to play a more pivotal role in dictating the direction of an artist’s work. For example, LSD was commonly given to interested test subjects to gauge the drug’s effects and was found to disinhibit normal sensory perceptions, launching the artist into a potentially productive psychedelic experience. These more psychoactive drugs can actually become a type of muse that influence the content of the art, the most famous example of these acid trips being “Lucy in the Sky With Diamonds...
