A hybrid supercomputer: Researchers integrate a quantum computer into a high-performance computing environment
2024-07-23 20:45:48
Working together, the University of Innsbruck and the spin-off AQT have integrated a quantum computer into a high-performance computing (HPC) environment for the first time in Austria. This hybrid infrastructure of supercomputer and quantum computer can now be used to solve complex problems in various fields such as chemistry, materials science or optimization.
Boneyard airplane sees new life as a NASA X-66 simulator
2024-07-23 20:45:48
NASA's X-66 aircraft, the centerpiece of its Sustainable Flight Demonstrator project, is taking the term "sustainable" to heart by reusing an old MD-90 cockpit as a base for its new X-66 simulator.
Study shows clear influence of driving noise on individual sound preferences in a car
2024-07-23 20:45:47
Loud or unpleasant driving noises can impair the enjoyment of music in the car. Some sound systems therefore dynamically adjust the volume and bass. However, individual sound preferences are not taken into account. A study from Fraunhofer IDMT in Oldenburg has now investigated the influence of background noise on the personal sound experience while driving—and shows how an adjustment of individual sound preferences once could improve the sound in the vehicle (and beyond).
Study shows abrasion emissions from trains can have an environmental impact
2024-07-23 17:15:10
In addition to exhaust emissions, abrasion emissions from tires and brakes have become increasingly important when assessing the environmental impact of traffic. However, the focus here was on road vehicles; rail was hardly considered.
Thirteen Brazilian Sharks Test Positive for Cocaine, Researchers Say
2024-07-23 16:26:59
More than a dozen sharks in Brazil have tested positive for cocaine -- elevating concerns that the open waters in the area are being contaminated with drugs and affecting wildlife.
Researchers: Demolishing buildings is bad for the planet—here's an alternative
2024-07-23 16:18:47
The construction industry is not on track to decarbonize by 2050 and uses more resources than most. In 2020, the UK produced a staggering 59.1 million tonnes of non-hazardous construction and demolition waste. Despite most of this material (92.6%) being recycled, much of it was crushed for use in roads and building foundations.
Proton-conducting materials could enable new green energy technologies
2024-07-23 15:43:58
As the name suggests, most electronic devices today work through the movement of electrons. But materials that can efficiently conduct protons—the nucleus of the hydrogen atom—could be key to a number of important technologies for combating global climate change.
Creating loops of liquid lithium for fusion temperature control
2024-07-23 15:43:56
Fusion vessels have a Goldilocks problem: The plasma within needs to be hot enough to generate net power, but if it's too hot, it can damage the vessel's interior. Researchers at the Princeton Plasma Physics Laboratory (PPPL) are exploring ways to draw away excess heat, including several methods that use liquid metal.
Message in a bottle: Combining mixed-color glass an option to boost recycling
2024-07-23 15:43:56
The glass bottles we toss in the recycling bin don't always end up where we expect. Only about 33% of glass is recycled in the United States, according to the Environmental Protection Agency, partly due to expenses like sorting bottles by color. Penn State scientists recently found that mass-produced soda-lime silicate glass from post-consumer bottles of different colors can be safely melted together in the recycling process, which could potentially lead to more bottles being recycled.
AI study reveals dramatic reasoning breakdown in large language models
2024-07-23 15:10:54
Even the best AI large language models (LLMs) fail dramatically when it comes to simple logical questions. This is the conclusion of researchers from the Jülich Supercomputing Center (JSC), the School of Electrical and Electronic Engineering at the University of Bristol and the LAION AI laboratory.
Researchers create bio-inspired 3D-printed solar steam generators for desalination
2024-07-23 15:10:54
Faced with the world's impending freshwater scarcity, a team of researchers in Singapore turned to solar steam generators (SSGs), which are emerging as a promising device for seawater desalination. Desalination can be a costly, energy-intensive solution to water scarcity.
Shenzhou-18 crew conducts emergency drill simulating space debris impact on Tiangong
2024-07-23 12:21:25
After China's Shenzhou-18 crew smoothly delivered their first spacewalk in early July, the three taikonauts recently conducted a series of examination and maintenance works on the Tiangong space station, as well as a full-system emergency drill in case of internal pressure loss in the space station due to potential space debris impact, China Central Television (CCTV) reported Sunday.
Enhancing the performance, stability of solid oxide cells via in-situ forming of dual phase strontium lanthanum ferrate
2024-07-22 23:22:10
Solid oxide fuel cell (SOFC) is a highly efficient and clean advanced energy conversion technology that converts chemical energy directly into electrical energy through electrochemical reactions and can be widely used for distributed and stationary power generation.
Bio-inspired lizard robot reveals what's needed for optimum locomotion
2024-07-22 23:06:15
Can a robot mimicking a climbing and walking lizard give new insights into the evolution and advantages of different movements in humans and other animals?
Bio-hybrid robotics need regulation and public debate, say researchers
2024-07-22 19:06:08
Researchers are calling for regulation to guide the responsible and ethical development of bio-hybrid robotics—a pioneering science which fuses artificial components with living tissue and cells.
Interfacial fracture of perovskite light emitting devices
2024-07-22 17:16:47
Research by SUNY Polytechnic Institute (SUNY Poly) President Dr. Winston Soboyejo and peers at Worchester Polytechnic Institute (WPI) titled, "Interfacial fracture of Perovskite Light Emitting Devices," has been published in the journal Extreme Mechanics Letters.
Converting captured carbon to fuel: Study assesses what's practical and what's not
2024-07-22 17:05:47
The struggle to cut emissions is real. Last year, the world emitted more than 37 billion metric tons of carbon dioxide, setting a new record high. As a result, sucking CO2 out of the atmosphere has become an increasingly popular idea. Governments worldwide are banking on this technology, called direct air capture, to help them achieve climate goals and avoid the worst consequences of climate change.
Researchers discover mathematical expression for 'blockchain trilemma'
2024-07-22 17:05:47
In blockchain development, there is a rule of thumb that only two of the following are valid simultaneously: scalability, security, and decentralization. However, the mathematical expression of that rule was still a work in progress.
