The Truth About Gender

When it comes to gender differences, everybody's an expert. But George Lazarus is a bit more expert than most. Although he doesn't study the subject formally, as a pediatrician in New York City he sees a lot of children, who are, after all, far better than adults at expressing their essential natures.

DARWIN'S REVENGE

Of nature's many guises, winter at the Arctic Circle would have to be one of the least subtle. It's hard to imagine that humans would have survived generations of frigid climate without some adaptation giving them a way to cope.

BIRD-FLU CHALLENGE

For Zhang Jianxin, a poultry farmer at the forefront of the virus wars, the threat of an influenza pandemic wasn't something that should be left to health officials a world away.

BIRD-FLU CHALLENGE

The parade of flushed faces through Dr. Jacqueline Spencer's medical practice in Long Island City, N.Y., usually starts in November, when brisk weather and runny noses help viruses make the rounds.

SELLING OUT FOR SCIENCE

By the time Californians go to the polls this week, they will have endured months of Biology 101 lectures from celebrity activists such as eBay founder Pierre Omidyar and producer Doug Wick.

TRAVELING SUPERLIGHT

Hybrid cars are all the rage, in part because they almost double the miles you can go on a gallon of gasoline. That's no small achievement, but to increase fuel efficiency even more, automakers will have to address another part of the equation: weight.

Power People

It's not hard to imagine corporate executives treating Terry Penney with skepticism. An engineering manager at the U.S. government's National Renewable Energy Laboratory in Golden, Colo., he speaks with such enthusiasm that he tends to start on his next thought before finishing the last one.

THE HYBRID ECONOMY IS GOING TO NEED AN ELECTRICAL GRID THAT CAN ACCOMMODATE EVERY AVAILABLE POWER SOURCE

THE DEVIL IS IN THE CLOUDS

Meteorologists routinely tell us what next week's weather is likely to be, and climate scientists discuss what might happen in 100 years. Christoph Schar, though, ventures dangerously close to that middle realm, where previously only the Farmer's Almanac dared go: what will next summer's weather be like?

In Search Of Really Small Tweezers

How do you put an atom to work? Unlike, say, a bowling ball, which has three holes for your fingers, atoms are hard to get a handle on. When scientists from Caltech set out to fashion a laser from a single atom, a big challenge was how to keep the atom still.

The Global Makeover

When the ancient Indian poet Kalidasa wrote his epic tale of love between Lord Shiva and his consort, Parvati, his vision of female beauty had little to do with the half-starved waifs of Western catwalks or the lean-muscled athletes of cereal boxes.

Overloaded?

Back in the dark ages, when comic books were the rage, South Korean kids would gather excitedly at the corner shop to get a look at the latest translation of "Slam Dunk," a Japanese series about high-school basketball players.

Troubled Seas

Scientists aboard the research ship Tangaroa had set out from Australia in search of a particular underwater mountain. It was located in the Norfolk Ridge, out in the middle of the Tasman Sea, and sonar maps suggested that it was just what they were looking for: gentle slopes free of rocks and crags, and a peak that rose to within 2,000 meters of the water's surface.

To Build A Baby

The extraordinary thing about Molly Nash is that she seems like a typical second grader in Englewood, Colorado. "She can be as stubborn as an ox," says Lisa Nash, her mother, "and she smarts off now and then." But like most 8-year-olds, she has redeeming qualities--a round, cheeky face, a toothy smile, brown bangs.

Ouch! That Feels Better

Lei Dao is lying on his stomach with his trousers pulled down. His doctor, Hong Na, twists and turns one needle into his hip, then another into his backside. "It hurts," cries Lei--then gives a clench-jawed laugh at what he's gotten himself into.

Crazy Speed Demon

When Joao Magueijo signed up for a graduate fellowship at Cambridge University in England in 1990, he thought he would be joining the rich tradition of Isaac Newton and his intellectual heirs, the ideal place for a young scientist to plumb the mysteries of the cosmos.

A Delicate Reprieve

When the storm of January 2002 struck, the small group of scientists who monitor the return of the monarch butterflies to the Trans-Volcanic Mountains in central Mexico each winter didn't think it was any big deal.

The Human Factor

Imagine being Ron Dittemore. For the past week, NASA's shuttle program manager has been the point man on the worst spaceflight disaster in 17 years. He's had to deal with grief for his lost colleagues, and guilt, perhaps, over not ensuring their safety.

The Fear Of Food

Tony Hall's career has always depended on his command of certain facts about corn. For instance, did you know that last year the United States produced more than 9 billion bushels, 42 percent of the world's supply?

Attack Of The Clones

During Christmastime in Italy, there's always a whiff of immaculate conception in the air. But this year Italians found themselves waiting for a wholly different kind of miracle birth--one that has nothing to do with religion.

Potatoes No More!

Albert Chung had raced the five-mile track in Mugello, Italy, so many times he knew just what the other motorcyclists competing against him were going to do--before they did it.

The Truth About Smog

Devra Davis peered into the South African bush trying to find a lion she had been told was no more than 20 feet away. No matter how hard she looked, she couldn't see it--until it suddenly roared and charged her vehicle at a seemingly impossible speed. (Fortunately, the beast was bluffing and pulled back at the last moment.) For Davis, this fright has come to epitomize the human capacity for looking without seeing.

What Freud Got Right

Sigmund Freud has been out of the scientific mainstream for so long, it's easy to forget that in the early-20th century he was regarded as a towering man of science--not, as he is remembered today, as the founder of the marginalized form of therapy known as psychoanalysis.

Primates: Family Report

The news on our cousins the primates is decidedly mixed. Monkeys and apes have been declining in population for years, and the latest survey by Conservation International confirms the worst.

Battle Against The Bugs

Nomthandazo Ngwenya's reaction upon learning one day last week that she had contracted malaria was to chastise herself for not figuring it out. "For 10 days I had diarrhea, stomach pains, no strength, sweats and cold shivers, and a splitting headache," she says. "I don't know why I didn't realize I had malaria." Ngwenya, 18, took an ambulance to Mosvold Hospital in Ingwavuma, a tiny town in northeastern South Africa, where doctors administered quinine.
