Demonstrating the technique in the cleanroom at the Center for Nanoscale Systems, a National Science Foundation–supported research facility at Harvard, Kats uses a machine called an electron beam evaporator to apply the gold and germanium coating. He seals the paper sample inside the machine’s chamber, and a pump sucks out the air until the pressure drops to a staggering 10-6 Torr (a billionth of an atmosphere).

Just about all parents would agree — infants undergo a nearly magical transformation from 3 to 6 months. Seemingly overnight, they can smile and laugh, and they squeal with delight when tickled. They babble, have “conversations” with those around them, and start to respond to their own names.
The Harvard Semitic Museum opened at its Divinity Avenue location in 1903 on land bought for a dollar from a benefactor.
The sturdy, granite-trimmed, brick building was at the edge of a Cambridge demi-wilderness called Norton Woods. It was next to a residence that has since been moved to Ware Street. Further down was a boardinghouse for immigrant Irishwomen, who cleaned and made beds in Harvard dormitories.
Almost 3,000 years ago there was Homer’s “Odyssey,” nearly the oldest work in the Western literary canon. Later came Plato’s “Symposium,” and later still “Oedipus the King,” by Sophocles. Then there was Dante’s “Inferno,” and soon Shakespeare’s “Hamlet.” Read more about Glimpsing Dublin from the wine-dark sea
The ability to adopt new behaviors and ideas — whether learned or invented — has helped humans develop everything from stone tools and agriculture to revolutionary communications technologies like the World Wide Web. But new research shows that this ability may come with a very real cost, in an increased exposure to potentially deadly diseases. Read more about A cost of culture
In a triumph for cell biology, researchers have assembled the first high-resolution, 3-D maps of entire folded genomes and found a structural basis for gene regulation, a kind of “genomic origami” that allows the same genome to produce different types of cells. The research appears online Thursday in the journal Cell. Read more about Creating ‘genomic origami’
It’s a cliché to say it takes a village to raise a child, but it’s a cliché some creatures have taken to heart.
A handful of animals, including ants, bees, termites, and some birds, are what scientists call “eusocial.” That is, they live in tight-knit groups in which some individuals give up some of their reproductive capacity to care for the offspring of others. Read more about Reproductive strategies
Leverett House’s McKinlock Hall reopened to students at the beginning of the academic year after 15 months of reconstruction. McKinlock is the second completed project in the House renewal initiative, which is one of the largest and most ambitious capital improvement campaigns in Harvard College history and a major campaign priority.

“The existing system in many developing countries is not working for the masses, so almost by definition you need entrepreneurship,” Tarun Khanna said of the social and economic issues facing India, Pakistan, Bangladesh, and other nations of South Asia. Read more about Shaping problem-solvers
