The new paintings weren't found in a secret room or beneath debris. In fact, they were right in front of everyones' faces this whole time, but faded enough that they couldn't be easily seen with the naked eye. Instead, scientists used a photo-enhancement technique to make the difference between colors more apparent, bringing long-lost paintings into view.
The big reveal was made by art expert Noel Hidalgo Tan, who was working at the site and spotted odd traces of reddish paint on the wall on day during his lunch break, LiveScience reports. Tan took some photos and didn't think much else of it. When he later uploaded the images to his computer and played around with them using a color-enhancing technique called decorrelation stretch analysis, he was shocked to find an entire menagerie of detailed imagery.
It's not the first time the technique, called decorrelation stretch, has been used in science. NASA uses DStretch to enhance photos from Mars and archaeologists the world over use it to make faded, ancient petroglyphs easier to study. The picture above this paragraph is a petroglyph image from Baja California enhanced with DStretch. Below, you can see what that same image looked like without the technique applied. It's easy to see how paintings could go totally unnoticed without it.
Researchers at UC Riverside and Centro de Investigación Científica y de Educación Superior de Ensenada have published a paper describing their ongoing success in setting a “transparent nanocrystalline yttria-stabilized-zirconia” into patients’ skulls, which reveal the patients’ brains so that the patients’ brains can be zapped with therapeutic lasers.
One million miles from Earth, hanging in space between Earth’s gravitational pull and the sun’s, is the DSCOVR satellite and NASA’s incredible EPIC camera. Every two hours, EPIC takes a photo of Earth “to monitor ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth.” The above video […]
In Botswana, conservation scientists from the University of New South Wales are painting eyes on the rear ends of cattle in an effort to deter lions from eating them. As the lions’ protected habitats shrink, they move closer to human settlements. In Botswana, the lions attack the livestock that the subsistence farmers count on. That […]
