A simple quantum internet with significant possibilities      (via sciencedaily.com)     Original source 

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.

The case for sharing carbon storage risk      (via sciencedaily.com)     Original source 

Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.

Scientists create an 'optical conveyor belt' for quasiparticles      (via sciencedaily.com)     Original source 

Using interference between two lasers, a research group has created an 'optical conveyor belt' that can move polaritons -- a type of light-matter hybrid particle -- in semiconductor-based microcavities. This work could lead to the development of new devices with applications in areas such as quantum metrology and quantum information.

Transforming waste carbon dioxide into high-value chemicals with a cost reduction of about 30%      (via sciencedaily.com)     Original source 

A team of scientists has developed a novel technique to convert carbon dioxide (CO2) from treated flue gas directly into high-value chemicals and fuels. This innovation sidesteps the conventional approach of using high-purity CO2 for electrochemical reduction processes, achieving significant cost savings of about 30%.

Artificial intelligence tool detects male-female-related differences in brain structure      (via sciencedaily.com)     Original source 

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.

How to make ubiquitous plastics biodegradable      (via sciencedaily.com)     Original source 

Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process. The plastic can't be broken down by biotechnological means, either. Researchers are looking for ways to rectify this: An international team decoded a bacterial enzyme that plays a key role in styrene degradation. This paves the way for biotechnological application.

Coming out to a chatbot?      (via sciencedaily.com)     Original source 

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.

Chatbots tell people what they want to hear      (via sciencedaily.com)     Original source 

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.

Just believing that an AI is helping boosts your performance      (via sciencedaily.com)     Original source 

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.
