Open Culture World's oldest color film footage discovered in museum archive (video) Cached away for over a century, the world's first color moving pictures have been shown for the first time yesterday, according to the National Media Museum in the UK. The celluloid, shot by inventor Edward Raymond Turner in 1899, was actually in black and white and it was only through a curator's research that its colorful significance was also unearthed. When the footage was first shot, each frame was run consecutively through red, green or blue gels, and the process needed to be reversed during projection to reveal the color. Fortunately, a blueprint by the inventor of how to do just that was also found, allowing the institution's team to replicate the process digitally to produce the final footage. This type of color gel processing didn't take off in the early 20th century due to the mechanical complexity, and it would have been inferior to a chemical process since each frame carried only one-third of the full color information.

Bill Nye warns: Creation views threaten US science | Nation & World LOUISVILLE, Ky. — The man known to a generation of Americans as "The Science Guy" is condemning efforts by some Christian groups to cast doubts on evolution and lawmakers who want to bring the Bible into science classrooms. Bill Nye, a mechanical engineer and star of the popular 1990s TV show "Bill Nye The Science Guy," has waded into the evolution debate with an online video that urges parents not to pass their religious-based doubts about evolution on to their children. Christians who view the stories of the Old Testament as historical fact have come to be known as creationists, and many argue that the world was created by God just a few thousand years ago. "The Earth is not 6,000 or 10,000 years old," Nye said in an interview with The Associated Press. Millions of Americans do hold those beliefs, according to a June Gallup poll that found 46 percent of Americans believe God created humans in their present form about 10,000 years ago.

Science Update: The Science Radio News Feature of the AAAS January 28, 2013 Cancer deaths have declined significantly since 1991. Podcast: Play in new window Transcript BOB HIRSHON (host): Cancer takes a dive. Death rates from cancer in the United States have dropped 20 percent since their 1991 peak. REBECCA SIEGEL (American Cancer Society): One of the biggest influences, of course, is the decrease in the number of people who are smoking. HIRSHON: Breakthroughs in treatment and early detection have also helped.
Science Update: The Science Radio News Feature of the AAAS January 29, 2013 Children are better at forming long-term memories than adults for a surprising reason. Podcast: Play in new window Transcript BOB HIRSHON (host): How young brains learn. Kids are like information sponges. JOE TSIEN (Georgia Regents University): You can think of it as the background noise is being reduced, and therefore the newly created information will be more robust. His team studied young mice who were bred to have adult levels of a memory receptor called NMDA. Children are better at forming long-term memories than adults.
Science Update: The Science Radio News Feature of the AAAS January 30, 2013 China’s “one-child” social policy may have unintended effects on the children. Podcast: Play in new window Transcript BOB HIRSHON (host): One child, left behind? For decades, much of China’s population has been limited to one child per family, with stiff fines for non-compliance. LISA CAMERON (Monash University, Australia): Being an only child as a result of the policy results in people being less trusting, more risk-averse, less competitive, less conscientious, and they’re also slightly more neurotic. HIRSHON: Cameron suspects that being part of a mandated, largely one child society may have effects beyond those of being an only child by parental choice.
Science Update: The Science Radio News Feature of the AAAS January 31, 2013 A salivary gland biopsy may finally make it possible to definitively diagnose Parkinson’s Disease in living patients. Podcast: Play in new window Transcript BOB HIRSHON (host): Finally, a test for Parkinson’s. As of now, Parkinson’s Disease can only be truly diagnosed by looking at brain tissue in an autopsy. CHARLES ADLER (Mayo Clinic College of Medicine): And we were able to find that in 9 of the 11 cases that we had enough tissue to study. HIRSHON: Adler notes that currently, autopsies of patients who had been treated for Parkinson’s sometimes show that they didn’t really have the disease. Until now, Parkinson's disease could not be definitively diagnosed until after death.
