Where have you gone, Marcus Welby?

Family doctors are a dying breed that is not being revived by medical students. This is the healthcare crisis the candidates should be talking about.

Where have you gone, Marcus Welby?
Topics:,

A friend of mine died not long ago from colon cancer. She was a fit, health-conscious middle-aged woman who phoned her family doctor, complaining of rectal bleeding. Her doctor was too busy to see her for several weeks; his medical assistant, also booked for several days, reassured her that most rectal bleeding is from hemorrhoids. “Wait a few weeks and see if it doesn’t go away,” he told her. The bleeding did stop, temporarily, then returned a few months later. When she finally saw her doctor, her colon tumor was inoperable. Whether her outcome would have been different with an earlier diagnosis can’t be known with certainty. But what can be said is this is not the way medicine should be practiced.

Although not often this dramatic, everyone has his or her own tale of long waiting times, inability to find a new family doctor, or general frustration getting prompt and adequate care. Just as the U.S. financial gurus failed to acknowledge the seriousness of our present credit crisis, today’s politicians are avoiding what promises to be a similar catastrophe in healthcare — the availability of primary care physicians.

The neuroscience of happiness

New discoveries are shedding light on the activities that make us happy. An expert explains

The neuroscience of happiness

They say money can’t buy happiness. But can a better understanding of your brain? As recent breakthroughs in cognitive science break new ground in the study of consciousness — and its relationship to the physical body — the mysteries of the mind are rapidly becoming less mysterious. But does this mean we’ll soon be able to locate a formula for good cheer?

Shimon Edelman, a cognitive expert and professor of psychology at Cornell University, offers some insight in “The Happiness of Pursuit: What Neuroscience Can Teach Us About the Good Life.” In his new book, Edelman walks the reader through the brain’s basic computational skills – its ability to compute information, perform statistical analysis and weigh value judgments in daily life – as a way to explain our relationship with happiness. Our capacity to retain memories and develop foresight allows us to plan for the future, says Edelman, by using a mental “personal space-time machine” that jumps between past, present and future. It’s through this process of motivation, perception, thinking, followed by motor movement, that we’re able not only to survive, but to feel happy. From Bayes’ theorem of probability to Shakespeare’s “Romeo and Juliet,” Edelman offers a range of references and allegories to explain why a changing, growing self, constantly shaped by new experiences, is happier than the satisfaction any end goal can give us. It turns out the rewards we get for learning and understanding the workings of the world really make it the journey, not the destination, that matters most.

Rise of the Super-Earths

Astronomers have discovered a giant new kind of planet that could hold life -- and they could change everything

Topics:,
This article is an adapted excerpt from the upcoming book, "The Life of Super-Earths," available on January 23 from Basic Books.

We love our planet Earth. We should — it is our home, and there’s no place like home. There can’t ever be a better place than Earth. Plenty of serious science literature supports that view in an emotionally detached manner. It is often called the “Goldilocks hypothesis”: the Earth is just the right size (not too big, not too small) and just the right temperature (not too hot, not too cold) for life to emerge here. Life is a rare thing. Perched on our little planet, we can’t see any other out there, or at least not yet — so a certain dose of Earth-centrism seems justified. Or is it?

“Stephen Hawking: An Unfettered Mind”: Portrait of a genius

A new biography of the world's most famous scientist celebrates his spirit and his ideas

stephen hawking

Stephen Hawking is the world’s most famous living scientist for two reasons that (despite his own wishes in the matter) are impossible to disentangle. The first is his disability, a motor neuron disease related to amyotrophic lateral sclerosis (ALS, often referred to as Lou Gehrig’s disease) that, beginning in his late teens, has rendered him severely disabled. Most people, when diagnosed with ALS, live only a few more years; Hawking has survived for 49, turning 70 on Jan. 8. The second source of renown is his work as a theoretical physicist and cosmologist, particularly on the nature of black holes and the origin of the universe.

Should we erase painful memories?

"Eternal Sunshine of the Spotless Mind" could soon become a reality -- but the concept raises some thorny questions

eternal sunshine

This article was adapted from the upcoming book, "Memory: Fragments of a Modern History," available in January from the University of Chicago Press.

One of the most tenacious themes of 20th-century memory research was the idea that people tormented by the memories of terrible experiences could benefit from remembering them, and from remembering them better. The assumption — broadly indebted to psychoanalysis — was that psychological records of traumatic events often failed to be fully “integrated” into conscious memories. As long as these records remained “dissociated,” the sufferer was compelled to “relive” them instead of benignly remembering them. The more fully and appropriately one remembered terrible events, the more attenuated would be their emotional power.

The science of warp

From time travel to interstellar communication, an expert explains what sci-fi gets right and wrong

time warp

Topics:,

“Back to the Future,” “A Christmas Carol,” the “Terminator” series, “Star Trek,” “Rip Van Winkle,” “Hot Tub Time Machine,” “Terra Nova” — the list goes on. We, as a culture, have been mesmerized by the idea of traveling in time: going back to fix life-changing mistakes we regret; going forward to get a sneak preview at what we’ll become. Equally transfixing is the notion of traveling through space, exploring galaxies and unknown universes far beyond our sight’s reach.
