Journals: USA, others need to re-tool their science programs

According to USA Today, the system of awarding science Ph.D.s needs to be either reformed or shut down, a provocative series of pieces in one of the world’s pre-eminent scientific journals says this week. According to the multipart series in the journal Nature, the world is awash in Ph.D.s, most of them being awarded after years of study and tens of thousands of dollars to scholars who will never find work in academia, the traditional goal for Doctors of Philosophy.

“In some countries, including the United States and Japan, people who have trained at great length and expense to be researchers confront a dwindling number of academic jobs and an industrial sector unable to take up the slack,” the cover article says…

Scientists move closer to live 3-D video

Researchers are working to achieve the "magic rate" of 30 frames per second.

In a development with important implications for future teaching and learning, scientists say they have taken a big step toward displaying live video in three dimensions—a technology that is much more advanced than 3-D movies and more like the “Star Wars” scene where a ghostly Princess Leia image pleads, “Help me, Obi-Wan Kenobi.”

In that classic movie, the audience sees her back before a new camera perspective shows her face. Such a wraparound view of a moving image was just movie-trick fantasy in the 1977 film, but now?
