There are several ways we can measure the progress of human civilization. Population growth, the rise and fall of empires, and our technological ability to reach for the stars. But one simple measure is to calculate the amount of energy humans use at any given time. As humanity has spread and advanced, our ability to harness energy is one of our most useful skills. If one assumes civilizations on other planets might possess similar skills, the energy consumption of a species is a good rough measure of its technological prowess. This is the idea behind the Kardashev Scale.

Organic semiconductors form the cornerstone of modern technologies, powering the screens we use in many of our digital devices. On top of this, they are also key materials in organic solar cells and medical biosensing devices, amongst other innovative applications. Dr. Seyhan Salman and her colleagues at Clark Atlanta University have been investigating organic semiconductors using advanced computational methods. Through this, her team hopes to pave the way to developing even more impressive technologies, which will benefit society in myriad ways.

On March 12, 1989, the English computer scientist who invented the World Wide Web, Sir Tim Berners-Lee sent a document to his colleagues at CERN titled “Information Management: A Proposal”. This proposal concerned the management of general information about the particle accelerators and experiments at The European Organization for Nuclear Research (CERN). In the proposal, Berners-Lee discussed the problems of information loss about complex evolving systems and suggested a solution based on a distributed hypertext system, which eventually became the World Wide Web, an Internet-based hypermedia initiative for global information sharing.

Scientists are building digital twins of the ocean

Ocean digitalization - cientists are building digital twins of the ocean
Scientists are building digital twins of the ocean

Before the term “digital twin” was first used twenty years ago (see notes 1), engineers at NASA were already developing ground-based replicas of spacecraft infrastructure. Today’s manufacturers are also seeing double, taking advantage of digital duplicates to better understand and predict product performance. Now the European Union (EU) scientists are looking to apply the same principles to the natural world and building more and more digital twins of the ocean.

Quasicrystals and Their Real-World Applications: Exploring the Exotic New Family of Materials

Quasicrystals
Quasicrystals

Quasicrystals are among the newest and most exciting discoveries in the wider field of materials physics – but to date, many aspects of their exotic physical properties remain entirely unexplored. Since soon after their initial discovery, Dr. Zbigniew Stadnik at the University of Ottawa has made important contributions to our understanding of quasicrystals, including their magnetic and electronic characteristics. Building on his decades of experience in the field, he now hopes to gain a complete understanding of the fundamental properties of these materials – potentially opening up a broad new range of real-world applications.

According to health professionals, the Covid-19 pandemic age might benefit from the use of the metaverse, a combination of virtual and real-world space. An expansion of the metaverse’s experience is needed so that its users can realize the need for medical education. The prefix “meta,” which refers to the virtual world, plus the suffix “verse,” which refers to the physical world, make up the term metaverse.
