People with voice disorders, including those with pathological vocal cord conditions or who are recovering from laryngeal cancer surgeries, can often find it difficult or impossible to speak. That may soon change.

Last month, the world experienced its warmest January ever measured, and February is likely to continue that streak.

2024 is already shattering heat records as temperatures soar around the world.

Although flexible sensors have gained a surge of exotic sensing capabilities in the past decade, the complex deformation, which usually results from forces or strains from multi-axes, can be challenging to measure due to the lack of independent perception of multi-axial stimuli.

In a new study published in the Journal of Remote Sensing in February 2024, researchers utilized data augmentation alongside the LightGBM machine learning model for the estimation of both diffuse and direct solar radiation. By leveraging sunshine duration data collected from over 2,453 weather stations throughout China, this research overcomes the limitations posed by sparse and unevenly distributed ground-based observations.

High metal prices can drive up the costs of electric car batteries, which will reduce their adoption. Car manufacturers are already responding to this by shifting to different technologies.

In 1879, Edison invented the incandescent lamp, which brought light to the night. In 1969, the first red light emitting diodes (LEDs) lamp came out. However, as the key to making white light bulbs, high-energy blue light has not been successfully commercialized.

Wetlands are crucial ecosystems for the filtration of excessive water in some parts of the world and for storing carbon, preventing the overheating of the atmosphere. This is why they are often called the ‘kidneys’ of the landscape. Moreover, they are home to numerous flora and fauna species and thus are vital as a variety…

Not far from the North Pole, the world is frozen for thousands of miles. Suddenly a snowy mound wiggles and reveals two dark eyes. The lump is transformed into the furry white body of a lone arctic fox. The canine casually shakes the blanket of snow off her thick coat—the key to her survival. But warm fur alone might not keep this fox alive during the polar winter, when temperatures rarely get above zero degrees Fahrenheit. Until spring arrives, this arctic fox will rely on some freeze-defying strategies, making it a champion of the cold.

Although they were once thought of as dangerous and unsanitary, swamps are actually very beneficial ecosystems and can function as a fuel source and water purifier.

In a corner of Kelsey Hatzell's lab sits a small jar filled with a material that has an ability far beyond what its nondescript appearance would suggest: a way to capture and release carbon dioxide from the atmosphere by simply changing the surrounding humidity.

Artificial intelligence aficionados are betting that the technology will help solve humanity's biggest problems, from wars to global warming, but in practice, these may be unrealistic ambitions for now.

EPFL researchers have shown that large language models primarily trained on English text seem to use English internally, even when they are prompted in another language. As AI increasingly runs our lives, this may have important consequences regarding linguistic and cultural bias.

Skoltech researchers have demonstrated that reinforced plastics can be recycled without loss of original mechanical properties, sometimes even with improved characteristics. Published in Composites Communications, the study brings hope for an environmentally sounder—and economically viable—production of construction parts, car, aircraft, and marine vessel components, high-end sports equipment and other articles that currently end their service life in landfills.

In northeast Bosnia's rolling hills, the local community is torn between fears of environmental ruin and hopes of riches from huge deposits of the critical minerals Europe needs for its green transition.

In a recent article published in the National Science Review, researchers have proposed a new operator learning framework called PIANO. PIANO uses self-supervised learning to extract representations containing physical invariants from partial differential equations (PDEs) systems with different physical mechanisms, thereby extending the generalization ability of neural operators to various physics scenarios.

Research and industry worldwide work on the commercialization of perovskite photovoltaics. Most research laboratories focus on solvent-based manufacturing processes because these methods are versatile and easy to use. Established photovoltaic industries, however, almost exclusively apply vacuum processes for the deposition of high-quality thin films.

A research team has successfully enhanced the performance and durability of all-solid-state batteries. This breakthrough was made possible through the implementation of a novel approach known as bottom electrodeposition. Their research has been published in Small.

Machine learning is a branch of artificial intelligence (AI) and computer science that focuses on the use of data and algorithms to allow computers to learn without explicitly being programmed. While discussions surrounding AI algorithms, such as ChatGPT and other generative models, are taking place at all levels of society, the machine learning capabilities of quantum computers are still somewhat unexplored.

As traditional energy methods increase in cost and take their toll on the environment, Penn State researchers are turning to two underutilized renewable resources, the sun and outer space, for solutions to generate electricity and passively cool down structures.
