Gold

X-rays can be used to detect pieces of gold somewhat smaller than this monster

Every year, Australian mining companies discard hundred of millions of dollars worth of gold. They're not doing it on purpose, it’s just that the standard industry technique of scanning mineral samples isn’t sensitive enough to detect small traces of the precious metal. Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Canadian company Mevex have tested a new technique using powerful X-rays that can detect these small trace amounts quickly and accurately.  Read More

There may be new hope for heart attack victims, in the form of patches that incorporate go...

When someone has a heart attack, the damaged heart tissue doesn’t grow back. Instead, it’s replaced by non-beating scar tissue. As a result, the heart is permanently weakened. Now, however, researchers at Tel Aviv University are getting promising results using patches that contain cardiac cells and gold nanofibers.  Read More

A newly-developed process gives gold mines an alternative to using cyanide for extracting ...

In the gold-mining process, the precious metal is often extracted from low-grade ore in a technique known as gold cyanidation. As its name suggests, the process utilizes highly-poisonous cyanide, some of which ends up entering the environment in the mines’ tailings. That’s not so good. Scientists at Illinois’ Northwestern University, however, recently announced their discovery of a new gold recovery process that’s based on a non-toxic component of corn starch.  Read More

A material known as a plasmonic polypeptide nanocomposite has been shown to strengthen las...

Stitches and staples may be on their way to becoming a thing of the past, thanks to a developing technology known as laser tissue welding. Now, a new gold-based solder has been created, that could make tissue welds in regions such as the intestines much stronger and more reliable.  Read More

The nanoparticle with a core of the element actinium, surrounded by four layers of materia...

Gold nanoparticles have already shown promise in precisely highlighting brain tumors, “blowing up” individual diseased cells, and developing a lung cancer breath test. Now researchers have created gold nanoparticles that allow an alpha particle-emitting element to be directed to small cancer tumors. The researchers say the gold coating keeps the powerful radioactive particles in place at the cancer site so they do negligible damage to healthy organs and tissue.  Read More

Scientists have developed a new process for changing the surface color of gold and other m...

Although a great many people like the “prestige” that comes with the natural color of their gold jewelry, teeth or vacuum cleaners, things are about to get a little more complicated – scientists from the University of Southampton have now devised a technique that causes gold (or other metals) to be seen in a variety of other colors ... green gold, anyone?  Read More

The Great Work of the Metal Lover forces extremophilic bacteria to metabolize high concent...

For centuries, the world's great thinkers were consumed by the search for the mythical Philosopher's Stone. Franciscan friar Roger Bacon is said to have penned a formula for its creation in the 13th century, legend would have us believe that German friar Albertus Magnus actually found a substance capable of transmuting base metals into gold or silver, and English scientist and mathematician Isaac Newton was a known devotee of the magnum opus. Researchers at Michigan State University (MSU) have put a microbial spin on the ancient quest by creating a bioreactor that forces bacteria to transform a toxic liquid that, as team member Kazem Kashefi says, "has no value into a solid, precious metal that’s valuable."  Read More

Every component of the GV62711 vacuum cleaner except for the bag, motor, and wheels is enc...

Every now and then, we here at Gizmag like to take a look at how the other half (or one percent) live. And why not? It's nice to occasionally fantasize about say, waking up in a private, underwater hotel room, to be chauffeured in a Mercedes-Benz to a weekend getaway on your own personal floating island. But does that fantasy involve personalized, gold-plated cleaning appliances? If it didn't before, it sure can now with GoVacuum's GV62711 vacuum cleaner and it's US$1 million price tag.  Read More

The new ultra-sensitive biosensor has been demonstrated by detecting very small concentrat...

A new ultra-sensitive test developed by scientists from the Imperial College London and Spain’s University of Vigo has the potential to detect the earliest stages of a disease, thereby giving any treatment the best possible chance of succeeding. The researchers claim their new biosensor test is capable of detecting biomarkers (molecules which indicate the presence of a disease) at concentration levels much lower than is possible with existing biosensors. While the new test has already proven capable of detecting a biomarker associated with prostate cancer, the team says their biosensor could be easily reconfigured to detect biomarkers related to other diseases or viruses.  Read More

Audi buys Ducati ... time to celebrate

Audi has purchased Ducati Motorcycles. Not Volkswagen Group (Audi's parent) , but Audi, which is a subsidiary of Volkswagen Group. It seems a very good fit. It's early days and the announcement has just been made, but as a fan of motorcycles in general and Ducati in particular, we'rew all running around here like rats with a gold tooth in reaction to the announcement. Audi has the enthusiast spirit in its DNA to appreciate the magic of the Ducati Brand and empower it. It will ensure the resources are there to enable the brand to prosper. The Supervisory Boards of AUDI AG and Volkswagen AG approved the acquisition today in Hamburg. Hang in there Valentino, the cavalry are coming.  Read More
