IN A NUTSHELL 🌊 Scientists are studying Earth’s deep-sea hydrothermal vents as a model for potential life on Europa. 🔬 James Holden’s team uses lab simulations to understand how microbes survive in extreme conditions. 🚀 The Europa Clipper mission aims to explore Europa’s ice shell and subsurface ocean, searching for signs of life. 🌌 Discoveries
A robot trained on videos of surgeries performed a lengthy phase of a gallbladder removal without human help. The robot operated for the first time on a lifelike patient, and during the operation, responded to and learned from voice commands from the team—like a novice surgeon working with a mentor.
The robot performed unflappably across trials and with the expertise of a skilled human surgeon, even during unexpected scenarios typical in real-life medical emergencies.
The work, led by Johns Hopkins University researchers, is a transformative advancement in surgical robotics, where robots can perform with both mechanical precision and human-like adaptability and understanding.
Quantum teleportation is a fascinating process that involves transferring a particle’s quantum state to another distant location, without moving or detecting the particle itself. This process could be central to the realization of a so-called “quantum internet,” a version of the internet that enables the safe and instant transmission of quantum information between devices within the same network.
Quantum teleportation is far from a recent idea, as it was experimentally realized several times in the past. Nonetheless, most previous demonstrations utilized frequency conversion rather than natively operating in the telecom band.
Researchers at Nanjing University recently demonstrated the teleportation of a telecom-wavelength photonic qubit (i.e., a quantum bit encoded in light at the same wavelengths supporting current communications) to a telecom quantum memory. Their paper, published in Physical Review Letters, could open new possibilities for the realization of scalable quantum networks and thus potentially a quantum internet.
Going forward, AI has the potential to help balance needs across regions, ensuring care delivery doesn’t compromise chronic or long-term care in the face of emergencies.
Ethical Considerations And Systemic Impact
While AI holds significant promise in healthcare, its implementation must be approached thoughtfully. Challenges such as bias in training data, lack of interoperability and concerns around patient consent and data privacy (particularly under HIPAA) need to be proactively addressed. Effective deployment of AI requires close collaboration between policymakers, clinicians and technologists to establish standards that ensure equitable and inclusive outcomes.
Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star. Using ESO’s Very Large Telescope (VLT), they observed a planetary disk with prominent spiral arms, finding clear signs of a planet nestled in its inner regions. This is the first time astronomers have detected a planet candidate embedded inside a disk spiral.
“We will never witness the formation of Earth, but here, around a young star 440 light-years away, we may be watching a planet come into existence in real time,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, and lead author of this study, published in Astronomy & Astrophysics.
The potential planet-in-the-making was detected around the star HD 135344B, within a disk of gas and dust around it called a protoplanetary disk. The budding planet is estimated to be twice the size of Jupiter and as far from its host star as Neptune is from the sun. It has been observed shaping its surroundings within the protoplanetary disk as it grows into a fully formed planet.
