A team of American researchers is on a treasure hunt for jewels — of both artistic and historic value.
This month, researchers from Denver were in Russia to document the work of Vasily Konovalenko, a former ballet set designer turned sculptor, who created scenes from Russian folk life in semiprecious stones.
In the 1980s, Konovalenko emigrated from what was then the Soviet Union in search of artistic freedom. Now, his legacy is divided between the U.S. and Russia.
He won a Pulitzer Prize for his writing, but just as influential as his print essays were his "thumbs up" and "thumbs down" movie reviews. Film critic Roger Ebert died Thursday after struggling for years with cancer. He was 70 years old.
His thumb may have made him famous on TV, but Ebert was first and foremost a print journalist. He worked on newspapers in grade school, high school and college. With his acumen for writing came a love of movies — and on July 12, 2005, proclaimed Roger Ebert Day by the city of Chicago, he told a crowd of admirers why movies matter.
Scientists say they have found a way to get a glimpse of people's dreams.
"Our results show that we can predict what a person's seeing during dreams," says Yukiyasu Kamitani, a researcher at the ATR Computational Neuroscience Laboratories in Kyoto, Japan.
Philosophers, poets and psychologists have long shared a fascination with dreams. But Jack Gallant, a neuroscientist at the University of California, Berkeley says solving the mystery of our dreams is one tough problem.
