Maltreatment during childhood can lead to long-term changes in brain circuits that process fear, researchers say. This could help explain why children who suffer abuse are much more likely than others to develop problems like anxiety and depression later on.
Great works of ancient engineering, like the Pyramids or Stonehenge, inspire awe in every beholder. But some onlookers also get inspired to figure out exactly how these structures were made.
Howard Stone, an engineer from Princeton University, had such a moment in Beijing's Forbidden City — a city-within-a-city of palaces and temples built in the 15th and 16th centuries. A carved, 300-ton slab that formed a ramp to one structure particularly caught Stone's eye. "How in the world did it get here?" he wondered.
India's launch Tuesday of a satellite bound for Mars is the latest milestone in a space race among Asian nations. China, though, is still seen as the leader. A decade ago, China became the third nation to put up a manned spacecraft; it has worked on a lunar rover, a space station as well as its own unmanned mission to Mars.
Sir Terry Pratchett is one of Britain's best-selling authors. His science-fiction series Discworld has sold millions of copies worldwide. Pratchett is incredibly prolific — since his first novel was published in 1971, he has written on average two books every year.
But in 2007, 59-year-old Pratchett announced that he had been diagnosed with early-onset Alzheimer's disease. As a result, Pratchett can no longer read.
Small flickering oil lamps known as diyas are lighting up Indian homes in South Asian communities around the globe on Sunday as hundreds of millions of people observe Diwali.
Otherwise known as the Festival of Lights, it's a religious celebration of self-awareness and reflection. Diwali is a public holiday in a number of other nations, but it's not nearly so well-known in the U.S., where families must rely on themselves to keep the tradition alive.
For years, Newark, N.J., had the reputation of being a crime-ridden, low-income city. Former Mayor Cory Booker helped change that perception.
Thursday, the Democrat was sworn in as a U.S. senator, and it's unclear what that means for the city's future.
While Booker brought attention — and funding — to Newark, he couldn't completely tackle the violence that has persisted for years. As mayoral candidates begin making their cases, crime is a common theme.
Today the beauty of Los Angeles is dramatically symbolic of the ancient prophecy the desert shall "blossom like a rose."
This blossoming was made possible by the birth of the Los Angeles Aqueduct, opened 100 years ago this month. The opening of the aqueduct might as well have been the birth of the modern West and the image of the city as a Garden of Eden.
The vast quantities of water the aqueduct moved made Los Angeles, Las Vegas, Phoenix and other cities across the region possible.
The small town of Rjukan has long had to make do without sunlight during the cold Norwegian winters.
But that changed Wednesday, when the town debuted a system of high-tech mirrors to reflect sunlight from neighboring peaks into the valley below.
Rjukan, originally founded 100 years ago as an industrial outpost for the energy company Norsk Hydro, is nestled between several mountains and does not receive direct sunlight from late September to mid-March — nearly six months out of the year.
