From The Economist

One sure giveaway of quack medicine is the claim that a product can treat any ailment. There are, sadly, no panaceas. But some things come close, and exercise is one of them. As doctors never tire of reminding people, exercise protects against a host of illnesses, from heart attacks and dementia to diabetes and infection.

How it does so, however, remains surprisingly mysterious. But a paper just published in Nature by Beth Levine of the University of Texas Southwestern Medical Centre and her colleagues sheds some light on the matter.

Dr Levine and her team were testing a theory that exercise works its magic, at least in part, by promoting autophagy. This process, whose name is derived from the Greek for “self-eating”, is a mechanism by which surplus, worn-out or malformed proteins and other cellular components are broken up for scrap and recycled.

The cigarette industry is not dying. It continues to reap unimaginable profits. It’s still winning lawsuits. And cigarettes still kill millions every year.

So says Stanford’s Robert Proctor, author of the new bombshell study, Golden Holocaust: Origins of the Cigarette Catastrophe and the Case for Abolition, a book the tobacco industry tried to stop with subpoenas and hundreds of thousands of dollars in legal fees.

Proctor, the first historian to testify in court against the tobacco industry (in 1998), warns that the worst of the health catastrophe is still ahead of us: Thanks to the long-term effects of cigarettes, “If everyone stopped smoking today, there would still be millions of deaths a year for decades to come.”

“Low-tar” cigarettes? “Light” cigarettes? Better filters? Forget it, he said. They don’t work. Today’s cigarettes are deadlier even than those made 60 years ago, gram for gram.

Half the people who smoke will die from their habit. A surprising number will die from stroke and heart attacks, not cancer.

Humanity has long dreamed of perfection, striving to be faster, stronger and brighter, pushing nature to the limit. Four centuries before people were conceived in a petri dish, Swiss alchemist Paracelsus claimed flawless little beings could be grown in pumpkins filled with urine and horse dung, but there is no record he produced a crop.

With the birth of Louise Brown in 1978, the test tube finally succeeded where the pumpkin had failed, and the year she turned 11, scientists moved beyond making life in a lab: They found a way to peer into an embryo’s genes and predict what that life might be like.

That ability is now morphing into a whole new approach to baby-making, one that gives people an unprecedented power to preview, and pick, the genetic traits of their prospective children

From the Atlantic

As Americans gather around holiday tables this year, many of us will be setting places for vegetarians and vegans. In some families, diverse diets co-exist peacefully. In others, well … maybe there’s a health-obsessed uncle who relishes warning that “Meat will kill you!” Or an idealistic college student, eager to regale her complacent elders with grim details of the cruelty and environmental damage wrought by factory farms. Or omnivores who resent the suggestion that they should worry — or feel guilty — about eating meat.

The three of us can relate to both sides of such discussions. Though reared by omnivorous families, as young adults we each came to the conclusion that meat was to blame for health problems, environmental destruction, and cruelty to animals. Collectively, we have lived 52 years vegan or vegetarian. Yet we no longer think that vegetarianism is the answer to these ills. Now — as a rancher, a hunter, and a butcher — we firmly believe foods from animals can be healthful, environmentally appropriate, and ethical.
