Quantum gravity aims to find a description of spacetime and gravity that obeys the rules of quantum mechanics.
Mark Zuckerberg says Meta AI is now “the most intelligent AI assistant” that’s available for free.
The U.S. Air Force Test Pilot School and the Defense Advanced Research Projects Agency were finalists for the 2023 Robert J. Collier Trophy, a formal acknowledgement of recent breakthroughs that have launched the machine-learning era within the aerospace industry. The teams worked together to test breakthrough executions in artificial intelligence algorithms using the X-62A VISTA aircraft as part of DARPA’s Air Combat Evolution (ACE) program. In less than a calendar year the teams went from the initial installation of live AI agents into the X-62A’s systems, to demonstrating the first AI versus human within-visual-range engagements, otherwise known as a dogfight. In total, the team made over 100,000 lines of flight-critical software changes across 21 test flights. Dogfighting is a highly complex scenario that the X-62A utilized to successfully prove using non-deterministic artificial intelligence safely is possible within aerospace.
“The X-62A is an incredible platform, not just for research and advancing the state of tests, but also for preparing the next generation of test leaders. When ensuring the capability in front of them is safe, efficient, effective and responsible, industry can look to the results of what the X-62A ACE team has done as a paradigm shift,” said Col. James Valpiani, commandant of the Test Pilot School.
Anduril, the Royal Australian Navy (RAN), the Advanced Strategic Capabilities Accelerator (ASCA) and Defence Science and Technology Group (DSTG) are pleased to unveil the first Ghost Shark manufactured prototype and announce that the Ghost Shark program is ahead of schedule and on budget. As Anduril moves to deliver an operationally relevant capability within a fraction of traditional defence timelines, early creation and testing of the first Ghost Shark has been critical for rapid learning and iteration. It’s a momentous advancement in the $140M co-development contract between RAN, DSTG and Anduril to design and develop the three ‘Ghost Shark’ extra-large autonomous undersea vehicles (XL-AUV) in three years in Australia. Ghost Shark is a modular, multi-purpose capability that can flexibly respond to the Australian Defence Force’s mission requirements, creating an agile force multiplier for Defence.
Dr Shane Arnott, Senior Vice President Engineering, Anduril Industries said: “Moving at the speed of relevance is Anduril’s signature. For Ghost Shark, we have assembled a unique high-powered engineering team of 121 people from the best-of-Australia, across tech, resources and defence, to fuel this progress. We have 42 Australian companies currently working on Ghost Shark, which is being designed, engineered and manufactured in Australia. We plan to manufacture at scale in Australia for the Royal Australian Navy, and then for export to our allies and partners around the world. Using novel scaled agile development techniques, we are combining both tech and defence sector development practices – and it’s paying big dividends. Ghost Shark is a program that we as Australians can be very proud of.”
David Goodrich OAM, Executive Chairman and CEO Anduril Australia said: “The timeline we set to design and produce three Ghost Sharks in three years in Australia, by Australians for the ADF, was extremely ambitious. I am excited to report that we are ahead of schedule and, importantly for a Defence program, we are on budget. We’re moving incredibly quickly on this program in lockstep with our ASCA, DSTG and the RAN partners. The strategic leadership and innovation insights provided by Prof Tanya Monro, Prof Emily Hilder and Vice Admiral Mark Hammond are key to our success.”
Researchers have shown that double-layer graphene can function both as a superconductor and an insulator, a property that could revolutionize transistor technology. This dual functionality allows for the development of nanoscale transistors that are highly energy-efficient.
An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be “switched” on and off, which has potential for developing tiny, energy-efficient transistors – like the light switch in your house but at a nanoscale. The Massachusetts Institute of Technology (MIT), USA, and the National Institute for Materials Science (NIMS), Japan, were also involved in the research. The results were published in the scientific journal Nature Communications.
The expansion of fiber optics is progressing worldwide, which not only increases the bandwidth of conventional Internet connections, but also brings closer the realization of a global quantum Internet. The quantum internet can help to fully exploit the potential of certain technologies. These include much more powerful quantum computing through the linking of quantum processors and registers, more secure communication through quantum key distribution or more precise time measurements through the synchronization of atomic clocks.
However, the differences between the glass fiber standard of 1,550 nm and the system wavelengths of the various quantum bits (qubits) realized to date represent a hurdle, because those qubits are mostly in the visible or near-infrared spectral range. Researchers want to overcome this obstacle with the help of quantum frequency conversion, which can specifically change the frequencies of photons while retaining all other quantum properties. This enables conversion to the 1,550 nm telecom range for low-loss, long-range transmission of quantum states.
For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers from Linköping University, Sweden, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals. Their findings are published in the journal Nature Synthesis.
Scientists have long tried to make single-atom-thick sheets of gold but failed because the metal’s tendency to lump together. But researchers from Linköping University have now succeeded thanks to a hundred-year-old method used by Japanese smiths.
“If you make a material extremely thin, something extraordinary happens – as with graphene. The same thing happens with gold. As you know, gold is usually a metal, but if single-atom-layer thick, the gold can become a semiconductor instead,” says Shun Kashiwaya, researcher at the Materials Design Division at Linköping University.
Researchers at Aalto University have discovered a new force acting on water droplets moving over superhydrophobic surfaces like black silicon by adapting a novel force measurement technique to uncover the previously unidentified physics at play. This force, identified as air-shearing, challenges previous understandings and suggests modifications in the design of these surfaces to reduce drag, potentially improving their efficiency and application in various fields.
Microscopic chasms forming a sea of conical jagged peaks stipple the surface of a material called black silicon. While it’s commonly found in solar cell tech, black silicon also moonlights as a tool for studying the physics of how water droplets behave.
Black silicon is a superhydrophobic material, meaning it repels water. Due to water’s unique surface tension properties, droplets glide across textured materials like black silicon by riding on a thin air-film gap trapped beneath. This works great when the droplets move slowly—they slip and slide without a hitch.

Research into quantum materials is leading to revolutionary breakthroughs and is set to propel technological progress that will transform industries such as mining, energy, transportation, and medical technology.
A technique called time-and angle-resolved photoemission spectroscopy (TR-ARPES) has emerged as a powerful tool, allowing researchers to explore the equilibrium and dynamical properties of quantum materials via light-matter interaction.
