Gold fever isn’t just a relic of history from the California Gold Rush or a fictional concept from shows like DuckTales. It’s a real phenomenon that continues to captivate people today. Welcome, gold enthusiasts! Let’s dive into the multifaceted world of gold and explore its many uses beyond just coins and jewelry.
Gold is not only valued for its beauty and rarity but also for its remarkable physical properties. It resists corrosion, making it incredibly durable. It’s also highly conductive, which means it can efficiently carry electricity. Additionally, gold is extremely malleable, allowing it to be hammered into thin sheets known as gold leaf. These sheets are so thin they feel like cloth, yet they retain all the properties of gold.
Gold’s reflective qualities and ability to be made into thin layers make it an ideal material for space exploration. For instance, the Hubble Telescope is equipped with layers of gold to prevent corrosion from the harsh space environment. Astronauts’ helmets often feature gold visors to reflect harmful cosmic rays, protecting their eyes during spacewalks.
Back on Earth, gold is used in various innovative ways. For example, the windows of the Mandalay Bay hotel in Las Vegas are coated with gold leaf to reflect sunlight and reduce cooling costs. Gold is also biocompatible, meaning it can safely interact with the human body. This property is utilized in nanotechnology, where gold resists bacteria and works well with the body’s defenses.
At the atomic level, gold isn’t just a shiny metal; it can appear in different colors like crimson or light blue and reacts predictably with certain proteins. This makes it useful in medical applications. Gold nanoparticles are used to detect cancer cells, and research has shown that combining these particles with tea can target prostate cancer cells.
Gold also aids in treating facial paralysis by being attached to the underside of the eyelid, where its weight helps with muscle function. Additionally, injecting gold into joints can alleviate arthritis symptoms, reducing swelling and pain, although the exact mechanism remains a mystery.
Gold contributes to cleaner air through its use in catalytic converters, which reduce harmful emissions from vehicles. A collaboration between NASA and Nanostellar in 2011 led to a significant reduction in emissions by incorporating gold into these converters, offering a cost-effective alternative to more expensive metals like platinum.
Gold is essential in the electronics industry. It can be drawn into thin strands, used to bond materials inside computer chips, and protect conductors like copper or silver from corrosion. This is why high-quality HDMI cables often feature gold plating.
From detecting cancer to protecting astronauts, cleaning the air, and enhancing electronics, gold’s versatility and usefulness are undeniable. Perhaps the historical Gold Rush was justified after all. As you ponder the many applications of gold, consider watching the drama unfold in Discovery’s new series “Klondike,” which premieres this Monday, January 20, at 9:00 PM Eastern, 8:00 Central.

Gold fever wasn’t just a concept from DuckTales or the California Gold Rush. It’s real, and it’s still happening. Hello, gold enthusiasts! Trace here. Thanks for watching DNews today. Discovery’s upcoming new series “Klondike” tells the story of the men and women who risked their lives to strike gold in the Yukon.
But gold isn’t just used to make coins and build governments. Gold resists corrosion, is highly conductive, and is highly malleable. If I took pure gold, a hammer, and an anvil, I could probably make gold leaf. It would feel like cloth, but it would be gold. You’ll also see it in space. Gold’s reflective properties and ability to be made very thin make it ideal for protection from the sun and the harsh environment out there. The Hubble Telescope contains layers of gold to keep it from corroding. Photos of astronauts during spacewalks show them wearing gold visors designed to reflect cosmic rays.
On the ground, they use gold leaf to cover the windows of Mandalay Bay in Las Vegas because it reflects light and heat so well that it lowers their cooling bills. Plus, gold is biocompatible, so you can actually consume it. My first drink in college had gold flakes in it. Gold is used in nanotechnology because it resists bacteria and interacts well with the body’s defenses.
At an atomic level, gold isn’t actually just gold in color; it can appear crimson or light blue, and it has predictable reactions with certain proteins. Gold is already used to detect cancer cells, but a study in the Proceedings of the National Academy of Sciences found that if you mix gold nanoparticles with tea and then consume it, the particles combine and target prostate cancer cells.
It’s not just nanomedicine. Pure gold attached to the underside of the eyelid can help people with facial paralysis. The weight of the gold is beneficial. Additionally, when injected into joints, pure gold can alleviate arthritis, although the exact reason for this is still unknown. The University of Washington states that injected gold can reduce swelling, damage, stiffness, and pain.
Gold also plays a role in protecting the air we breathe. If you own a car purchased after 1975, it probably has a catalytic converter, which is designed to convert harmful gases into less harmful ones. In 2011, a partnership with NASA and a company called Nanostellar reduced emissions by one fifth by using gold in catalytic converters. Most cars use even more expensive metals in the converter, like platinum, so this is a significant advancement.
This remarkable material detects and fights cancer, protects astronauts and satellites, cleans the air, and eases arthritis. Gold is also used to enhance electronics. Much like gold leaf, you can stretch pure gold into strands 10 to 200 microns thick. Those strands are used to bond materials inside computer chips.
It’s used on a larger scale to protect conductors like copper or silver from corrosion, which is why those HDMI cables can be quite expensive. This precious material is incredibly useful. Perhaps the Gold Rush was all worth it. You can watch the drama unfold and decide for yourself. “Klondike” premieres this Monday, January 20, at 9:00 PM Eastern, 8:00 Central, on Discovery.
