A team of Montreal researchers has lent scientific credibility to the view that smoking marijuana can ease chronic neuropathic pain and help patients sleep better.

People suffering from neuropathic pain often turn to opioids, antidepressants and local anesthetics, but those treatments have limitations and the side effects can be punishing. Many physicians and policy-makers, however, are reluctant to advocate the use of cannabis since there has been little scientific research into its effectiveness, even though patients champion its use.

The American economy is once again tilting toward danger. Despite an aggressive regimen of treatments from the conventional to the exotic — more than $800 billion in federal spending, and trillions of dollars worth of credit from the Federal Reserve — fears of a second recession are growing, along with worries that he country may face several more years of lean prospects.

Yet even as vital signs weaken — plunging home sales, a bleak job market and, on Friday, confirmation that the quarterly rate of economic growth had slowed, to 1.6 percent — a sense has taken hold that government policy makers cannot deliver meaningful intervention. That is because nearly any proposed curative could risk adding to the national debt — a political nonstarter. The situation has left American fortunes pinned to an uncertain remedy: hoping that things somehow get better.

The water is blue and warm, the visibility is perfect. There might be no better place in the world to learn to scuba dive than the glassy seas around Key West, at the southernmost tip of the U.S. As I gradually master my buoyancy and hover 15 feet below the surface, I can see schools of small yellow groupers gathered beneath the dive boat, giving wide berth to a blade of a barracuda. A spiny lobster shyly crawls across the seafloor. This colorful diversity of life — like swimming through a tropical aquarium — is all thanks to the shallow coral reefs that exist west of Key West. The world's reefs are the bases for sea life — home to a quarter of all the fish on the planet.

The American economy could experience painfully slow growth and stubbornly high unemployment for a decade or longer as a result of the 2007 collapse of the housing market and the economic turmoil that followed, according to an authority on the history of financial crises.

That finding, contained in a new paper by Carmen M. Reinhart, an economist at the University of Maryland, generated considerable debate during an annual policy symposium in Jackson Hole, Wyoming, organized by the Federal Reserve Bank of Kansas City, which concluded on Saturday.

It weighs in at more than 130 pounds, but the authoritative guide to the English language, the Oxford English Dictionary, may eventually slim down to nothing.

Oxford University Press, the publisher, said Sunday so many people prefer to look up words using its online product that it’s uncertain whether the 126-year-old dictionary’s next edition will be printed on paper at all.
