The conversational diagnostic artificial intelligence system AMIE (Articulate Medical Intelligence Explorer) has potential as a real-world tool for clinical history-taking and diagnostic dialogue, based on its performance in simulated consultations.
A joint research team has successfully demonstrated the complete confinement of mechanical waves within a single resonator—something long thought to be theoretically impossible. Their findings, published on April 3 in Physical Review Letters, mark a major breakthrough in the century-old mystery of bound states in the continuum (BIC). The team is from POSTECH (Pohang University of Science and Technology) and Jeonbuk National University.
Many technologies around us—from smartphones and ultrasound devices to radios—rely on resonance, a phenomenon in which waves are amplified at specific frequencies. However, typical resonators gradually lose energy over time, requiring constant energy input to maintain their function.
Nearly a century ago, Nobel laureates John von Neumann and Eugene Wigner proposed a counterintuitive concept: under certain conditions, waves could be trapped indefinitely without any energy leakage. These so-called bound states in the continuum (BIC) are like whirlpools that remain in place even as a river flows around them. But for decades, scientists believed this phenomenon could not exist in a compact, single-particle system.
Using advanced microscopes that capture brain cell anatomy and activity, a portion of a mouse’s brain was mapped and rendered into a 3D atlas that creates new possibilities for neuroscience.
Ora Biomedical, in partnership with Rapamycin Longevity Lab, announces the successful funding of the first subproject under its ambitious initiative to conduct a rapid lifespan analysis of 601 mTOR inhibitors in roundworms.
With $50,000 secured, Ora Biomedical will now commence the next phase of the first subproject. This will be a high-throughput screening of 301 mTOR inhibitors using its cutting-edge WormBot-AI technology. This milestone marks an important step toward identifying next-generation compounds that could be more effective than rapamycin, which is currently seen as the golden standard because of its good longevity effects in multiple species.
Mitchell Lee, CEO of Ora Biomedical, emphasized the importance of this research by stating: “The potential of targeting aging to broadly improve healthy lifespan is clear from decades of studies with compounds like rapamycin. However, even for well-validated molecular targets like mTOR, we still don’t know the best interventions. We at Ora Biomedical are proud to partner with Rapamycin Longevity Lab to advance our understanding around targeting mTOR and related kinases for maximizing healthy lifespan. None of this work is possible without support from visionary donors and organizations like the Lifespan Research Institute, the nonprofit behind Lifespan.io, with whom we have partnered to create pathways for donations to advance longevity science. To all those involved, thank you again, and we are excited to get to work!”
NTHU researchers create world’s smallest quantum computer using a single photon, breaking records in quantum computing innovation…
Tantalizing clues in 4-billion-year-old asteroid Bennu samples could reveal particular molecular formations that some scientists say support the workings of consciousness.
The current prototype impressively produces 200 milliliters of hydrogen per hour with a promising 12.6% energy efficiency.
“Water and energy are both critically needed for our everyday life, but typically, if you want to produce more energy, you have to consume more water,” said Lenan Zhang, assistant professor in the Sibley School of Mechanical and Aerospace Engineering in Cornell Engineering, who led the project.
Zhang added: “On the other hand, we need drinking water, because two-thirds of the global population are facing water scarcity. So there is a bottleneck in green hydrogen production, and that is reflected in the cost.”
Silicon Valley startup Lightmatter has developed a novel computer chip that can speed up artificial intelligence processes and save electricity in the process. The company focuses on using beams of light to move data between computers rather than using electric signals.
Connection speeds are a great matter of concern when it comes to artificial intelligence due to its complex software. This complexity requires the software to be spread over many computers.
