Lithium-ion batteries powered the device on which these words appear. From phones and laptops to electric vehicles, lithium-ion batteries are critical to the technology of the modern world — but they can also explode. Comprising negatively and positively charged electrodes and an electrolyte to transport ions across the divide, lithium-ion batteries are only as good as the limitations of their components. Liquid electrolytes are potentially volatile at high temperatures, and their efficiency can be limited by nonuniformity and instabilities in the other components.   Researchers are working toward developing safer, ...

The sky is no longer the limit — but taking flight is dangerous. In leaving the Earth’s surface, we lose many of the cues we need to orient ourselves, and that spatial disorientation can be deadly. Astronauts normally need intensive training to protect against it. But scientists have now found that wearable devices which vibrate to give orientation cues may boost the efficacy of this training significantly, making spaceflight slightly safer. “Long duration spaceflight will cause many physiological and psychological stressors which will make astronauts very susceptible to spatial disorientation,” ...

Niigata, Japan – The research group of Professor Kamimura in Niigata University have demonstrated the complementary role of peripheral and central nervous system on GH–IGF-1axis activation to prevent MASLD progression. IGF-1 ameliorates fatty infiltration in the liver. Its release is controlled by GH and GH activation is managed by peripheral or central nervous system. However, the role of this axis in MASLD developmental phase has not been well identified. Our study demonstrated that the GH–IGF-1 axis is significant in inhibiting the progression of MASLD. In addition to the peripheral autonomic ...

The gene-editing technology known as CRISPR has led to revolutionary changes in agriculture, health research and more. In research published in Nature Catalysis, scientists at Florida State University produced the first high-resolution, time-lapsed images showing magnesium ions interacting with the CRISPR-Cas9 enzyme while it cut strands of DNA, providing clear evidence that magnesium plays a role in both chemical bond breakage and near-simultaneous DNA cutting. “If you are cutting genes, you don’t want to have only one strand of DNA broken, because the cell can repair it easily without editing. You want both strands to be broken,” said Hong ...

ITHACA, N.Y. – Online grocery carts tend to include less variety and fewer fruits and vegetables than those in a trip to a brick-and-mortar supermarket – but online shoppers are less susceptible to unhealthy impulse buys, according to a new Cornell University study. In an analysis of nearly 2 million shopping trips, the researchers found that within a given household, Instacart baskets are more similar to each other from week to week than in-store carts, with more than twice as many overlapping items between successive trips to the same retailer. Nutritionally, however, ...

Generative artificial intelligence tools like ChatGPT, an AI-powered language tool, and Midjourney, an AI-powered image generator, can potentially assist people with various disabilities. These tools could summarize content, compose messages or describe images. Yet the degree of this potential is an open question, since, in addition to regularly spouting inaccuracies and failing at basic reasoning, these tools can perpetuate ableist biases. This year, seven researchers at the University of Washington conducted a three-month autoethnographic study — drawing on their own experiences as people with and without disabilities — to test AI tools’ utility for accessibility. Though ...
