Published Making batteries takes a lot of lithium: Some could come from gas well wastewater



A new analysis suggests that if it could be extracted with complete efficiency, lithium from the wastewater of Marcellus shale gas wells could supply up to 40% of the country's demand.
Published Final dust settles slowly in the deep sea



'Dust clouds' at the bottom of the deep sea, that will be created by deep-sea mining activities, descend at a short distance for the biggest part. Yet, a small portion of the stirred-up bottom material remains visible in the water at long distances.
Published Studying bubbles can lead to more efficient biofuel motors



By studying how bubbles form in a drop of biodiesel, researchers can help future engines get the most energy out of the fuel.
Published Now we know, what gets roots to grow: Can help in future droughts



A biological mechanism familiar to people who fast helps plant roots grow strong. The discovery provides an answer to a long-unanswered question and a deeper understanding of the 'mouths' of plants that can help to develop climate-resilient crops.
Published Polyglycerol coating: A breakthrough in safer nanoparticle environmental remediation



Engineered nanoparticles (NPs), commonly utilized in environmental remediation, can pose significant toxicity risks upon ingestion by organisms. Researchers have now devised a solution to this challenge by creating a hydrophilic coating, utilizing polyglycerol (PG) functionalization, for NPs. This coating effectively prevents NP aggregation inside organisms' bodies and facilitates easier passage, thereby reducing accumulation. Applicable to various NPs, the novel surface functionalization approach holds promise for addressing concerns about NP toxicity in environmental remediation.
Published Climate change is most prominent threat to pollinators



A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
Published A simple quantum internet with significant possibilities



It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.
Published Next-generation sustainable electronics are doped with air



Semiconductors are the foundation of all modern electronics. Now, researchers have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study is a significant step towards future cheap and sustainable organic semiconductors.
Published Scientists develop an affordable sensor for lead contamination



A new system could enable simple, low-cost detectors for monitoring water for lead contamination, and potentially other heavy metals as well.
Published Petroleum, chlorine mix could yield harmful byproducts



A new study shows that chlorine mixed with petroleum in water can potentially produce inadvertent byproducts harmful to human health.
Published Virtual reality becomes more engaging when designers use cinematic tools



Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published Artificial intelligence tool detects male-female-related differences in brain structure



Artificial intelligence (AI) computer programs that process MRI results show differences in how the brains of men and women are organized at a cellular level, a new study shows. These variations were spotted in white matter, tissue primarily located in the human brain's innermost layer, which fosters communication between regions.
Published How wildfires change soil chemistry



Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
Published Using artificial intelligence to speed up and improve the most computationally-intensive aspects of plasma physics in fusion



Researchers are using artificial intelligence to perfect the design of the vessels surrounding the super-hot plasma, optimize heating methods and maintain stable control of the reaction for increasingly long periods. A new article explains how a researcher team used machine learning to avoid magnetic perturbations, or disruptions, which destabilize fusion plasma.
Published Artificial intelligence tool to improve heart failure care



The powerful new AI tool can predict heart failure outcomes in specific patients, helping doctors improve care.
Published Coming out to a chatbot?



Today, there are dozens of large language model (LLM) chatbots aimed at mental health care -- addressing everything from loneliness among seniors to anxiety and depression in teens. But the efficacy of these apps is unclear. Even more unclear is how well these apps work in supporting specific, marginalized groups like LGBTQ+ communities.
Published Chatbots tell people what they want to hear



Chatbots share limited information, reinforce ideologies, and, as a result, can lead to more polarized thinking when it comes to controversial issues, according to new research. The study challenges perceptions that chatbots are impartial and provides insight into how using conversational search systems could widen the public divide on hot-button issues and leave people vulnerable to manipulation.
Published Just believing that an AI is helping boosts your performance



Sometimes it seems like an AI is helping, but the benefit is actually a placebo effect -- people performing better simply because they expect to be doing so -- according to new research. The study also shows how difficult it is to shake people's trust in the capabilities of AI systems.
Published Cats purrfectly demonstrate what it takes to trust robots



Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published New work extends the thermodynamic theory of computation



Physicists and computer scientists have recently expanded the modern theory of the thermodynamics of computation. By combining approaches from statistical physics and computer science, the researchers introduce mathematical equations that reveal the minimum and maximum predicted energy cost of computational processes that depend on randomness, which is a powerful tool in modern computers.
