A team of computer scientists and roboticists with members from Texas A&M University in the U.S., and the Mohamed Bin Zayed University of Artificial Intelligence in Abu Dhabi, working with a colleague from Boston Dynamics, has configured a robot made by Boston Dynamics to seek out and stun weeds using a small blowtorch. The team has posted a paper describing their efforts to the arXiv preprint server.

Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light—photons—into small chunks.

Perovskite solar cells (PSCs) are highly regarded for their exceptional performance and straightforward fabrication. However, traditional hole transport layers (HTLs) like poly (triarylamine) (PTAA), nickel oxide (NiOx), and poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT) have inherent limitations that impede efficiency and stability. These materials often suffer from issues such as hydrophobicity, high reactivity, and acidity, which negatively affect the overall performance of PSCs.

Designing the spatial arrangement of underground powerhouses involves numerous complex parameters and boundaries, requiring frequent reference to various cases and specifications. Traditional methods struggle to efficiently retrieve this information, leading to suboptimal designs and extended project timelines. Due to these challenges, there is a pressing need for a more intelligent and efficient approach to streamline the design process, enhance accuracy, and improve project management in hydropower engineering.

To achieve carbon neutrality, advancements in energy conversion and storage technologies are essential. Current aqueous energy devices suffer from performance limitations due to the trade-off between permeability and selectivity in permselective membranes. This trade-off hampers the efficiency of energy conversion and storage systems, necessitating the development of membranes that can balance these properties effectively. Due to these challenges, further research is required to explore innovative membrane structures that can enhance the performance of energy conversion and storage devices.

On August 23, 1969, the coastal freighter MV Noongah departed Newcastle bound for Townsville with a cargo of steel and 26 crew. The 71-meter ship had been a regular sight along the eastern seaboard for a decade as it hauled cargo between cities up and down the coast.

Perovskite solar cells (PSCs) are celebrated for their exceptional photovoltaic performance and affordability. However, the high cost of charge transport materials remains a major obstacle to their commercialization. Conventional materials like 2,2',7,7'-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene (Spiro-OMeTAD), are expensive and complex to produce.

QUT researchers have found that pedestrians' crossing decisions involving automated vehicles (AVs) are most influenced by nearby pedestrians.

To transition away from fossil fuels and towards renewables—which are intermittent by nature—we'll need to rework our entire system of power storage, transmission and distribution. Yet experts haven't yet found the right energy mix or power storage system, or how to balance supply and demand effectively.

A sustainable source for clean energy may lie in old soda cans and seawater. MIT engineers have found that when the aluminum in soda cans is exposed in its pure form and mixed with seawater, the solution bubbles up and naturally produces hydrogen—a gas that can be subsequently used to power an engine or fuel cell without generating carbon emissions. What's more, this simple reaction can be sped up by adding a common stimulant: caffeine.

Chemists at Kaunas University of Technology (KTU), Lithuania have synthesized materials that can improve solar elements for indoor use. Such photovoltaic cells, which can also be integrated into various electronic devices, generate electricity even in low-light conditions.

A new method to measure the continuous spectrum of light, developed in the lab of University of Houston professor of electrical and computer engineering Jiming Bao, is set to improve thermal imaging and infrared thermography, techniques used to measure and visualize temperature distributions without direct contact with the subject being photographed.

Using AI-generated datasets to train future generations of machine learning models may pollute their output, a concept known as model collapse, according to a new paper published in Nature. The research shows that within a few generations, original content is replaced by unrelated nonsense, demonstrating the importance of using reliable data to train AI models.

Self-amputation may seem like a drastic move, but it's a survival tactic that's proved particularly handy for numerous creatures. Yale roboticists have drawn inspiration from lizards, crabs, and other animals who shed parts of themselves without looking back, all for the purpose of moving forward.

ECHO and the penguins seem to be getting along, researchers say.

Computer science researchers have developed a new method for predicting what data wireless computing users will need before they need it, making wireless networks faster and more reliable. The new method makes use of a technique called a "digital twin," which effectively clones the network it is supporting.

Residential buildings account for a large percentage of global energy consumption, and many countries around the world are looking into effective solutions to this issue amidst the ongoing energy crisis. Consistent with global efforts to shift away from fossil fuels, an attractive option is to make houses self-sufficient by having them generate their electricity—something that is usually achieved using photovoltaic (PV) systems.

When Hurricane Beryl swept across Texas in early July, it left more than 3 million homes and businesses without power for days or longer. Local hospitals reported a spike in heat-related illnesses amid the widespread power outages, and at least seven people died from extreme heat.

A research team at Rice University led by James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering, is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.

With a continuous rise in the global population, energy consumption and its associated environmental and economic costs are also increasing.
