Researchers in California described Wednesday their new method for mass-producing the key ingredient for the herbal drug artemisinin, the most powerful antimalarial on the market. Already, the French drugmaker Sanofi is ramping up production at a plant in Italy to manufacture the ingredient and the drug.
Global health advocates say they expect this new method of producing artemisinin will at last provide a stable supply of the drug and cut the overall cost of malaria treatment.
Scientists reported Wednesday that they had developed a way to measure how much pain people are experiencing by scanning their brains.
The researchers hope the technique will help doctors treat pain better, but the work is also raising concerns about whether the technique might interfere with doctors simply listening to their patients.
Now, when someone is in pain, a doctor has no way to judge its severity except to ask questions, a method that often is inadequate.
Federal officials say a large study of premature infants was ethically flawed because doctors didn't inform the babies' parents about increased risks of blindness, brain damage and death.
The study involved more than 1,300 severely premature infants at nearly two dozen medical institutions between 2004 and 2009. The infants were randomly assigned to receive two different levels of oxygen to see which was better at preventing blindness without increasing the risk of neurologic damage or death.

The patent medicines sold in days gone by may, contrary to the name, not have had real government patents. But that didn't stop their makers from claiming the concoctions could cure ailments ranging from indigestion to jaundice and fever.
Now, researchers have put some of these old elixirs and pills in the Henry Ford Museum's large collection of patent medicines to a modern test. They found a mix of potentially harmful metals like lead and mercury along with benign ingredients, including calcium and iron.
