Interesting case coming up in the Supreme Court.
The case, to be heard in the court's next term beginning in October, pits North Carolina against a video production company documenting the salvaging of the shipwreck Queen Anne's Revenge, which ran aground in 1718 and was discovered in 1996.The state, which owns the pirate ship and its artifacts, has posted video and photos shot by Nautilus Productions as part of its tourism efforts. It enacted a statute, known as "Blackbeard's Law," to convert the salvage effort into public record...
"After Nautilus spent nearly two decades creating works by photographing and filming (at considerable risk) underwater excavation of Blackbeard’s famed Queen Anne’s Revenge, the state brazenly pirated them," the company protested.

New tests were conducted to date the "Kula Footprints," once thought to be 250,000 year-old Neanderthal footprints.
The results showed that the footprints were made 4,700 years ago, meaning it couldn't have been Neanderthals (who went extinct about 40,000 years ago), but rather modern humans, who left them.
"The two independent dating approaches showed internally consistent results and collectively suggest that the volcanic eruption was witnessed by Homo sapiens during the prehistoric Bronze Age, 4,700 years ago and 245,000 years later than originally reported," study co-researcher Martin Danišík, a research fellow in Earth and planetary sciences at Curtin University in Perth, Australia, said in a statement.

I tend to be skeptical of such dating techniques.
That is a huge difference - 250,000 years compared to 4,700 years.

| Three Sun-Purpled Found Glass Bottles |
Here are three sun-purpled glass bottles. Some clear glass bottles will turn purple with exposure to the sun. Not too many of mine have turned.
The two in the back are more purple than is apparent from the photos, but the front one is definitely the most purple.
Purpled bottles can be more desirable, and artificial treatment is sometimes used to make them turn.
The Corning Glass Museum web site provides the following information.
Many glassmakers through the centuries have attempted to produce clear, colorless glass. Impurities, especially iron oxide, in the batch ingredients that were melted to make the glass often resulted in glass that was greenish instead of the desired "water clear."
An interesting characteristic of colorless glasses which contain manganese dioxide as a decolorizer is their tendency to turn different shades of purple when exposed to the rays of the sun or to other ultra-violet sources. It is a photochemical phenomenon that is not yet perfectly understood. It is generally accepted that the ultra-violet light initiates an electron exchange between the manganese and iron ions. This changes the manganese compound into a form that causes the glass to turn purple.
