According to Dr. Nadim Darwish, the lead researcher from the School of Molecular and Life Sciences at Curtin University, the study found that the spike proteins of coronaviruses attach to and become stuck on specific types of surfaces.“Coronaviruses have spike proteins on their periphery that allow them to penetrate host cells and cause infection and we have found these proteins becomes stuck to the surface of silicon, gold, and copper through a reaction that forms a strong chemical bond,” Dr. Darwish said.“We believe…

Zircons vary in shape, size, and texture. Credit: Chetan Nathwani Zircons are common, hardy minerals that can be found in rocks up to 4 billion years old. Their structure and texture can reflect the conditions in which they formed, earning them a reputation as nature's time capsules. And according to new research, with the power of machine learning, scientists can mine zircon textures to identify valuable mineral deposits.…

Replica of the Valencina Slate Plaque with inserted owl feathers on the two drilled holes at the top of the plaque. Credit: Juan J. Negro Ancient owl-shaped slate engraved plaques, dating from about 5,000 years ago in the Iberian Peninsula, may have been created by children as toys, suggests a paper published in Scientific Reports. These findings may provide insights into how children used artifacts in ancient European…

Experts in Chile on Tuesday were investigating the appearance of an enormous sinkhole, bigger than a tennis court, that has appeared near a copper mine in the Atacama desert.Experts were dispatched to examine the hole, some 32 meters (104 feet) across and twice as deep, which appeared in an area about 800 kilometers (nearly 500 miles) north of Santiago over the weekend, the National Geology and Mining Service (Sernageomin) said in a statement.  A 100-meter security perimeter has been erected around the hole in the Tierra…

Copper has long been known for its ability to kill viruses and bacteria on contact, which is why it's often professionally coated onto commonly touched items such as doorknobs. A new copper nanowire spray may allow everyday folks to give existing surfaces the same treatment, using a spray can.The technology is being developed via partnership between the US Department of Energy's Ames National Laboratory, Iowa State University, and the University at Buffalo. It builds upon previous Ames research, in which a copper ink was…

At 5:29 am on the morning of 16 July 1945, in the state of New Mexico, a dreadful slice of history was made.The dawn calm was torn asunder as the United States Army detonated a plutonium implosion device known as the Gadget – the world's very first test of a nuclear bomb, known as the Trinity test. This moment would change warfare forever.  The energy release, equivalent to 21 kilotons of TNT, vaporized the 30-meter test tower (98 ft) and miles of copper wires connecting it to recording equipment. The resulting fireball…
