New flavor for M&Ms

But analysts see a few difficulties in marketing only to Hispanics. "The second generation of Americans wants to be super-American," said Morgan Stanley analyst David Adelman. Another hurdle is the opposite: The product may not seem authentic enough. M&M are made in plants in New Jersey and Tennessee.

The Food and Drug Administration has just given approval for the marketing of an unusual dental device that helps end both chronic and migraine headaches. It's called the NTI-tss system (for Nociceptive Trigeminal Inhibition-tension suppression system), and it prevents patients from clenching the temporal muscle tightly during sleep. It's the clenching that brings on the headaches. The clear device fits over the patient's front teeth to keep the jaws from coming together in a tense clenching motion.

Artist Dianne Price, 52, who has suffered from migraines since she was a teenager, has tried the device for the past six weeks without one headache. "I would clench my jaw so hard at night I'd crack a tooth," said Price. "And I'd get migraines every three or four weeks. ... So, for me it's been nothing short of a miracle." The device can be worn during sleep, or it can be made less conspicuous for day wear. It costs from $280 to $900. Insurance carriers will be considering coverage.
