2024-08-05 13:51:44
A team of researchers from Nagoya University in Japan has developed a loop heat pipe (LHP) that can transport up to 10 kW of heat without the need for electricity. This heat transport capability is the largest in the world.
Cracking the code of life: New AI model learns DNA's hidden language
2024-08-05 13:51:42
DNA contains foundational information needed to sustain life. Understanding how this information is stored and organized has been one of the greatest scientific challenges of the last century.
New technology for energy device that heals itself from damage incurred while generating electricity
2024-08-05 13:51:42
A team led by Professor Lee Joo-hyuk of the Department of Energy Engineering at DGIST has developed an ionic polyurethane-based triboelectric generator with self-healing, biodegradable, and high electro-positive properties. The work is published in the journal Nano Energy.
Five ways to model text using networks
2024-08-05 13:51:09
The explosive growth of AI "chatbots" over the last few years and their ability to generate text that simulates human writing, often very accurately, has focused attention on how text is structured.
Ultra-stable, record high brightness perovskite LEDs with promising applications
2024-08-05 13:51:09
Perovskite materials are significant for enhancing the development and performance of light-emitting diodes (LEDs). However, there are certain technological limitations in advancing overall device efficiency, brightness and lifetime, with the operational stability of perovskite LEDs (PeLEDs) remaining a major challenge.
Thinking about the rise of brain-inspired computing
2024-08-05 13:51:08
The recent widespread and long-lasting chaos caused by Microsoft outages across the globe exemplifies just how integral computing has become to our lives. Yet, as computer hardware and software improve, arguably the most sophisticated and powerful computer we know of is still the human brain.
Towards smart cities: Adaptive multi-LIDAR sensor networks for indoor use
2024-08-05 13:51:08
The explosive technological growth that we've witnessed over the past few decades has set the stage for the development of smart cities, whose purpose is to empower citizens in urban areas through various services. By sensing the inside and/or outside of various urban spaces, smart cities can help with tasks such as routing, logistics, traffic management, crime prevention, and many more.
Staying in the loop: How superconductors are helping computers 'remember'
2024-08-05 06:30:05
Computers work in digits—0s and 1s, to be exact. Their calculations are digital; their processes are digital; even their memories are digital. All of which require extraordinary power resources. As we look to the next evolution of computing and developing neuromorphic or "brain-like" computing, those power requirements are unfeasible.
A flapping microrobot inspired by the wing dynamics of rhinoceros beetles
2024-08-04 12:41:59
The wing dynamics of flying animal species have been the inspiration for numerous flying robotic systems. While birds and bats typically flap their wings using the force produced by their pectoral and wing muscles, the processes underlying the wing movements of many insects remain poorly understood.
Hope or hype? NZ needs to be realistic about the clean energy potential of green hydrogen
2024-08-03 15:04:41
The recent failure of a deal to deliver hydrogen-powered trucks to New Zealand, and the removal of a NZ$100 million government rebate scheme for green hydrogen users in the 2024 budget, make a transition to the much-lauded energy technology increasingly less certain.
Engineers explore cellulose nanofibrils to enhance 3D-printed concrete
2024-08-03 09:38:38
A research team led by engineers at the University of Virginia School of Engineering and Applied Science is the first to explore how an emerging plant-based material, cellulose nanofibrils, could amplify the benefits of 3D-printed concrete technology.
Bronze Age technology could aid switch to clean energy

Technology with roots going back to the Bronze Age may offer a fast and inexpensive solution to help achieve the United Nations climate goal of net zero emissions by 2050, according to recent Stanford-led research in PNAS Nexus.
New Jersey-sized "dead zone" that can kill fish and marine life emerges in Gulf of Mexico
2024-08-02 17:58:54
The "dead zone" in the Gulf of Mexico has created more than 4 million acres of habitat with little to no oxygen that could kill marine life.
Scientists design a framework to optimize nuclear material coatings discoveries
2024-08-02 15:06:56
Nickel-based alloys, critical materials used in many advanced nuclear reactors, come with unwanted baggage. Aside from being very expensive, nickel ore is mined in politically sensitive parts of the world. The ore also has a high moisture content that can pose safety issues for those transporting the ore in cargo ships because the cargo can slosh around and create a load imbalance.
