ASIAN-FOCUSED GENOMIC STUDY.
A recent study in Nature analyzed genetic data from the Born in Guangzhou Cohort Study, focusing on the link between maternal health and fetal development in over 58,000 Chinese families. This research, significant for involving an East Asian population typically under-represented in genomic studies, revealed several key findings. Higher maternal blood pressure was associated with the birth of lighter, shorter babies. The study also uncovered unique genetic variants in East Asian mothers, including one linked to increased bile acid levels and a heightened risk of liver disease during pregnancy. This variant might offer protection against hepatitis B, prevalent in China. Furthermore, discrepancies were found in the impact of genetic variants on traits between mothers and their babies, suggesting age or epigenetic factors could influence genetic risk profiles. Although the study offers new insights, larger sample sizes and experimental studies are needed for confirmation. (Nature)
AN AUTONOMOUS GENERAL AI CHILD.
“Tong Tong,” the world’s first virtual AI entity with capabilities akin to a three or four-year-old child, was developed by Chinese scientists and unveiled at the Beijing Institute for General Artificial Intelligence’s exhibition. This groundbreaking AI, named “Little Girl,” can independently perform and assign tasks, showing advanced interaction skills like tidying up and cleaning spills. Unlike conventional large language models, Tong Tong has her own emotions, intellect, and is capable of autonomous learning, decision-making, and understanding human common sense. BIGAI director Zhu Songchun, a prominent AI researcher, emphasizes the importance of creating AI entities that comprehend the real world and possess a broad range of skills. The team also introduced the “Tong Test,” a comprehensive AI capability assessment framework covering vision, language, cognition, motion, learning, and values. This test aims to develop general AI that can integrate into human environments, driven by an understanding of causality and values, ensuring AI serves society effectively and safely.

RELAX WITH VR.
A new study has demonstrated the superior effectiveness of the Flourishing-Life-of-Wish Virtual Reality Relaxation Therapy (FLOW-VRT-Relaxation) in improving the well-being of palliative care patients, surpassing traditional diaphragmatic breathing relaxation methods. Developed by Olive Woo and her team, FLOW-VRT-Relaxation combines standard relaxation techniques with immersive VR experiences aimed at inducing a state of ‘flourishing,’ characterized by positive emotions and a sense of fulfillment. In a clinical trial with 128 terminal cancer patients, this VR therapy significantly reduced physical and emotional symptoms compared to standard care. Patients experienced joy, awe, and a sense of accomplishment, often fulfilling last wishes virtually. The study, which showed a 26.6% improvement in physical symptoms and a 47.4% improvement in emotional symptoms for the VR group, highlights the potential of VR-assisted therapy as an effective, scalable, and personalized approach in palliative care. The researchers plan to further investigate the long-term impacts of this innovative treatment. (Frontiers In)
LEARNING LANGUAGE THROUGH A CHILD’S EYE.
Vong et al. conducted a unique study to understand how young children learn to associate words with objects or concepts, using a more naturalistic approach than traditional laboratory methods. They used head-mounted video recordings to capture a child’s first-person experiences from 6 to 25 months old in real-world settings. The team developed the Child’s View for Contrastive Learning (CVCL) model by applying machine learning. This model pairs video frames with corresponding spoken words and embeds them in shared representational spaces, enabling the child to differentiate between visually similar objects within a concept, like animal versus alphabet puzzles. The study shows that children can learn many word-referent mappings and generalize to new visual referents through this exposure. The findings demonstrate that essential aspects of grounded word meaning are learnable through joint representation and associative learning, providing insights into early language acquisition and cognitive development.

JAPAN’S LUNAR LANDER SAYS GOODNIGHT.
Japan’s SLIM (Smart Lander for Investigating Moon) mission, which successfully executed a precision landing on the rim of Shioli crater on January 19, has entered a dormant state due to the onset of the cold lunar night. Despite initially facing challenges with its solar cells after landing nose-down, SLIM reactivated 10 days later when sunlight reached its panels. Operated by the Japan Aerospace Exploration Agency (JAXA), SLIM used its Multi-Band Camera (MBC) to study the lunar surface’s composition, focusing on minerals like olivine by analyzing light spectra. A final image was shared by JAXA’s SLIM account on X, formerly Twitter, before the spacecraft powered down. The mission must now wait through the 14.5-Earth-day-long lunar night and hope for favorable conditions in the next lunar daytime for a possible revival. Despite these challenges, SLIM has already achieved its primary and extended mission goals, including precision landing, deploying rovers, and collecting valuable science data. JAXA plans to release scientific findings derived from the data, which aims to shed light on the moon’s origin. (space.com)
PRE-MADE SPACE STATION.
The Starlab commercial space station, a joint venture between US-based Voyager Space and European-based Airbus, will be launched on SpaceX’s Starship rocket. Scheduled for launch no earlier than 2028, Starlab will have half the pressurized volume of the International Space Station. Voyager Space chose SpaceX for its reliability and high-cadence launch capabilities, allowing Starlab to be launched in a single flight. This single-launch approach is cost-effective, avoiding the high expenses of building and integrating in space, as learned from the International Space Station experience. Starlab, which will be ready for human habitation almost immediately after launch, is competing with other private ventures like Axiom Space, Blue Origin, and Vast Space to replace the International Space Station, likely to retire in 2030. NASA has provided seed funding for these initiatives, with further selection for development and testing expected next year. The challenge for these stations, including Starlab, lies in finding customers beyond NASA, which significantly funds ISS operations. Starlab’s partnership with Airbus might give it an edge, potentially attracting European astronauts and missions, as European Space Agency might prefer a station with European involvement over those solely operated by US companies.

A SPACE UMBRELLA… FOR REAL.
Facing Earth’s escalating climate crisis, scientists are considering a space-based solution reminiscent of science fiction: a giant sunshade to block a fraction of solar radiation, potentially cooling the planet by 1.5 degrees Celsius. This concept, once on the fringes of climate discussions, is gaining traction as Earth’s temperature rises. Recent proposals include scattering space dust, using a ‘space bubbles’ shield, or tethering a solar shield to an asteroid. A team led by Dr. Yoram Rozen at the Technion-Israel Institute of Technology plans to build a prototype. The full-scale sunshade, about the size of Argentina, would cast a diffused shade on Earth. Critics argue the concept is astronomically expensive and risky, suggesting more focus on reducing greenhouse gas emissions and atmospheric carbon removal. However, proponents see sunshades as a necessary exploration to complement other climate mitigation strategies. The idea, dating back to 1989, envisions a sunshade positioned at Lagrange Point One. Despite skepticism, advancements in space technology and the urgency of climate change are bringing this once far-fetched idea into serious consideration. (New York Times)
