European team use proprietary ‘SeaFi’ technology to send furthest wireless broadband transmission from ship-to-shore ever achieved without satellite. A team of scientists working off the west coast of Ireland have set a new world record for the furthest broadband transmission from a ship at sea back to land without satellite or cellular connection. The new record is 36.83km (19.9 nautical miles) set on Saturday, 26 May 2023, off the coast of the Aran Islands. The team based at Aran Island Research Station…
Analysis of lightweight nuclei emerging from gold ion collisions offers insight into primordial matter phase changes. Physicists analyzing data from gold ion smashups at the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, are searching for evidence that nails down a so-called critical point in the way nuclear matter changes from one phase to another. New findings from members of RHIC’s STAR Collaboration published in Physical…
A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision – about 3 times more precise than any other technique – the mass of a galaxy containing a quasar, as well as their evolution in cosmic time. Knowing the mass of quasar host galaxies provides insight into the evolution of galaxies in the early universe, for building scenarios of galaxy formation and black hole development. The results are…
Imagine being able to try on different clothes on a virtual avatar and see how they look from every angle. Or adjusting the direction your pet is looking in your favorite photo. You could even change the perspective of a landscape picture. These types of photo edits have always been challenging, even for experts. A novel AI tool now promises that with just a few mouse clicks, anyone can achieve edits like these effortlessly. The method is being developed by…
NASA grant funds aeroacoustic research… As noise levels in urban spaces swell, a multi-university partnership seeks to turn down the volume on urban air mobility vehicles. Drone delivery is rapidly taking off in major cities, with rotor-powered rideshares not far behind. The convenience promised by electric vertical take-off and landing vehicles generates a substantial buzz – not just from excitement but from all the noise generated by rotors filling the sky. To address key challenges facing the future of air…
… realign autonomously when cut. The advance presages a new era of robots and prosthetics wrapped in self-healing synthetic materials imbued with human-like sense of touch. Human skin is amazing. It senses temperature, pressure, and texture. It’s able to stretch and spring back, time and again. And it provides a barrier between the body and bad things in the world—bacteria, viruses, toxins, ultraviolet radiation and more. Engineers are, accordingly, keen to create synthetic skin. They imagine robots and prosthetic limbs…
Ceramics recycling – energy-efficient and low in emissions… Silicon carbide is a popular industrial material for many applications. The extremely hard, heat-resistant material is used for refractory components and semiconductors, for instance. But its production is energy-intensive and emits a lot of carbon dioxide, as well as producing large amounts of by-products and waste products. Researchers at Fraunhofer Institute for Ceramic Technologies and Systems IKTS have developed RECOSiC©, an especially environmentally friendly recycling process that turns these by-products and waste…
A method for personalized sound experience… Developing an audio device that offers optimum sound experience to all people is not easy. The great challenge is that each person has their own listening preferences. For this reason, the Oldenburg Branch for Hearing, Speech and Audio Technology HSA of the Fraunhofer Institute for Digital Media Technology IDMT has developed adaptive algorithms as well as intuitive methods for adjusting personal sound. Together with a customer, this technology has now been successfully integrated in…
So far, it has not been possible to explain the causes of around half of all rare hereditary diseases. A Munich research team has developed an algorithm that predicts the effects of genetic mutations on RNA formation six times more precisely than previous models. As a result, the genetic causes of rare hereditary diseases and cancer can be identified more precisely. Variations of genetic sequence occur relatively frequently – on average, one in a thousand nucleotide of a person’s genome…
A University of Virginia-led study about a class of materials called associative polymers appears to challenge a long-held understanding of how the materials, which have unique self-healing and flow properties, function at the molecular level. Liheng Cai, an assistant professor of materials science and engineering and chemical engineering at UVA, who led the study, said the new discovery has important implications for the countless ways these materials are used every day, from engineering recyclable plastics to human tissue engineering to…
… can circulate in superconductors in ways not seen before. Within superconductors little tornadoes of electrons, known as quantum vortices, can occur which have important implications in superconducting applications such as quantum sensors. Now a new kind of superconducting vortex has been found, an international team of researchers reports. Egor Babaev, professor at KTH Royal Institute of Technology in Stockholm, says the study revises the prevailing understanding of how electronic flow can occur in superconductors, based on work about quantum…
A team at Sandia National Laboratories is developing materials to tackle what has become one of the biggest problems in the world: human exposure to a group of chemicals known as PFAS through contaminated water and other products. Sandia is now investing more money to take their research to the next level. “It’s in the news constantly. It seems every day we hear of another product that is contaminated. We saw sparkling water with PFAS, toilet paper with PFAS, so…
Car2Human communication at LASER 2023… How do you decide whether a pedestrian needs to wait or it’s safe for them to cross the road in front of a car? In today’s world, car drivers and pedestrians simply exchange a brief eye contact or small hand gestures to express their intentions to one another. But how will future autonomous cars communicate? Researchers involved in the MaMeK project are seeking to answer that question. They will be presenting their findings at the…
Do intelligent people think faster? Researchers at the BIH and Charité – Universitätsmedizin Berlin, together with a colleague from Barcelona, made the surprising finding that participants with higher intelligence scores were only quicker when tackling simple tasks, while they took longer to solve difficult problems than subjects with lower IQ scores. In personalized brain simulations of the 650 participants, the researchers could determine that brains with reduced synchrony between brain areas literally “jump to conclusions” when making decisions, rather than…
Energy-flexible operation of pressure die-casting systems. Due to the high energy consumption of melting and holding furnaces, the price of the energy source represents a significant cost factor in the production of castings. The price of electricity fluctuates over the course of the day. As a result, companies should design their energy consumption flexibly. Together with its partners, the Fraunhofer Institute for Manufacturing Engineering and Automation IPA is developing a bivalent furnace that enables dynamic switching between gas and electricity….
