The Science of Manufacturing Supplements

Take a dive into the world of manufacturing supplements.

Most popular vitamin and mineral supplements provide no health benefit

Instead of dietary supplements, focus on a healthy diet, researchers say.

Meet ‘Virgin Rainbow’: quite possibly the finest opal ever unearthed

As a geologist, I’m not into gemstones and “pretty rocks” – but every once in a while, I see a rock so spectacular that it just blows my mind. Such is the case with “Virgin Rainbow”, a glorious opal unveiled by the South Australian Museum in Adelaide.

GeoPicture of the Week: Pyromorphite

Pyromorphite is as awesome as it sounds. The mineral is composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. However, most of the time, it is found as a secondary mineral in the oxidized zones of lead ore deposits. The color of the mineral is usually some bright shade of green, yellow or

Rock with 30,000 diamonds found Russian diamond mine

Do you fancy diamonds? If the answer is ‘yes’, then you’ll absolutely love this rock extracted from a Russian mine. The rock is littered with over 30,000 diamonds, something which is extremely rare and may yield valuable information about how diamonds form in natural conditions. What’s unlucky for gem sellers was very fortunate for researchers – because the tiny diamonds

Earth’s most abundant mineral finally gets a name

What’s the most common mineral on Earth? Is it quartz, limestone? Maybe olivine? Well, if you take into consideration the entire planet, the most common mineral would be something known as silicate-perovskite – but now, that mineral finally has a name. On June 2, bridgmanite was approved as the formal name for silicate-perovskite – possibly of the Earth’s most plentiful yet elusive mineral known to

New and unique mineral discovered – it’s strikingly beautiful!

There are over 4,000 known and fully described minerals in the world. Even so, scientists have yet to discover them all, and every year a couple are added to the list. The last to join the ranks is a new and unique mineral discovered by researchers at University of Adelaide in  the Polar Bear peninsula of Western Australia. Called putnisite, the mineral

New evidence suggests the moon never was abundant in water

An eminent team of US researchers found that it is highly unlikely that the moon ever once harbored important quantities of water, after studying a mineral called apatite. Generally speaking, scientists have always though the moon was water barren, a theory confirmed by the initial rock samples brought back by the Apollo missions, however in the past decades or so

GeoPicture of the week: Mimetite

Mimetite, whose name derives from the Greek which means “imitator” is not really like any other mineral I’ve seen. It’s basically a lead arsenate chloride mineral which forms as a secondary product in lead deposits. It has no major uses, being a minor ore of lead, being usually gathered by collectors. It’s not used as a gemstone because of its

GeoPicture of the day: Titanium

Believe it or not, this is actually titanium, though not natural. It was obtained through a process called iodide process (or crystal bar process), unlike natural titanium, which is usually found chemically bonded in various ways found in rock ores. For more information, you should really check out this video (it’s actually a series with many other ones).

GeoPicture of the week: Crocoite from Tasmania

Crocoite is a fairly rare mineral in many parts of the world, consisting of lead chromate, PbCrO4. The relative rareness comes from the way it forms: it requires an oxidation zone of lead ore bed and presence of what are called ultramafic rocks, which act as a source of chromium. Ultramafic rocks are 90% mafic minerals (dark colored, high magnesium and iron content)

Shorties: 4.5 billion meteorite shows new mineral

A recently analyzed 4.5 billion years old meteorite yields one of the oldest minerals known in our solar system: krotite. The mineral is not actually new, in that it was thought to be only a man-made constituent of some high-temperature concrete, according to study researcher Anthony Kampf, curator of Mineral Sciences at the Natural History Museum of Los Angeles County
