Gold

  • A bright explosion in the sky in 2016 has now been identified as a kilonova, where two neutron stars collide and create gold.
  • Since electronics are always shrinking, engineers need to find ways to make smaller components too. Now, scientists from the University of Leeds have managed to make the thinnest gold ever created, measuring just two atoms thick. That makes it functionally two-dimensional, joining graphene.

    Scientists from Australia’s CSIRO have now found a fungus species that mines for gold and even decorates itself with the precious particles. Following the fungus could be a new, environmentally-friendly way to find large underground gold deposits.
  • Researchers at Cambridge University have managed to create the smallest pixels in the world, about a million times tinier than those in a phone. These new pixels could be used in huge, flexible displays that are relatively easy to manufacture and cheaper to run.
  • Melting gold normally requires temperatures upwards of 1,064° C (1,947° F), but physics is never quite that simple. A team of researchers has now found a way to melt gold at room temperature using an electric field and an electron microscope.
  • ​If you need to close up an injury or incision in human body tissue, you use sutures, staples or a surgical adhesive … right? Well, if technology that's currently being developed at Arizona State University gets commercialized, liquid silk combined with gold may eventually be a better way to go.
  • Rolls-Royce Motor Cars has joined forces with the House of Fabergé to create the first Fabergé Imperial Egg in 101 years. The gold egg decorated with diamonds and amethysts features the luxury car mark's iconic Spirit of Ecstasy hood ornament sculpted from rock crystal.
  • Researchers at the University of California, Riverside have found a way to use viruses to build gold nanobeads, which can then be used to purify water and could eventually help cut the cost and time required to produce electronic components.
  • Sandia engineers have developed the most durable metal alloy ever created. Made up of a combination of platinum and gold, the new material is 100 times more wear-resistant than high-strength steel, and the first metal alloy to join the same class as diamond. It also produces its own lubricant.
  • Researchers at CNBP have developed a new targeted treatment for cancer. Chemotherapy drugs are wrapped in “nano-bubbles” called liposomes, which are then injected into the desired part of the body and made to release their payload on demand, by applying X-ray radiation.
  • ​A remarkable new study has successfully used the CRISPR gene editing system to edit a specific gene in mice engineered to have fragile X syndrome, a disorder often related to autism. The single gene edit in the live mice resulted in significant improvements in repetitive and obsessive behaviors​.

    ​It's never a good thing when donated human blood – or even the blood in our bodies – is infected with bacteria. Scientists at the University of California San Diego, however, are developing a means of removing such blood-borne microbes using tiny ultrasound-powered robots.
