ALPHAFOLD 3 SPARKS DEBATE OVER ACCESS, SCIENTIFIC FREEDOM.

The recent unveiling of AlphaFold 3 by Google DeepMind, an AI program promising significant advancements in protein structure prediction and drug discovery, has sparked both excitement and controversy. Published in Nature, the tool is praised as transformative but criticized for its restricted access and lack of available computational code, violating Nature’s own code availability policies. Over 650 researchers have signed an open letter expressing disappointment, accusing the journal of inequitable policy enforcement. Unlike its predecessors, AlphaFold 3 is only accessible via a web server with strict usage limits, hindering potential research and competitive drug discovery efforts. Critics argue that withholding the code under the guise of biosecurity seems disingenuous, particularly when weighed against its scientific benefits. In response to the backlash, DeepMind has hinted at future plans to make the model available for academic purposes, reflecting ongoing tensions between proprietary technology and open scientific inquiry.

MUSIC EVOLUTIONARY MYSTERY UNIVERSAL TRAITS SUGGEST ANCIENT ORIGINS.

Charles Darwin was puzzled by music, considering it a profound mystery due to its universal presence yet unclear survival advantage. He theorized that music evolved as a means for mating attraction, a view met with skepticism by peers like William James who suggested music was merely an incidental product of neural activity. This debate persists, with some modern scientists viewing music as a cultural invention independent of natural selection, while others explore evolutionary explanations using big data. A recent innovative study involved 75 researchers who recorded songs from 55 languages, finding common acoustic features across cultures that suggest a possible evolutionary origin. These songs differed from speech in aspects like pitch and tempo, hinting at a potential universal aspect of music. Critics, however, caution that biases could influence such findings. The study proposes that music’s distinctive traits may play unique communicative roles, supporting various theories from social cohesion to parental bonding. (New York Times)

QUANTUM ENTANGLEMENT ACHIEVED IN URBAN OPTICAL FIBERS.

Three research teams have successfully demonstrated quantum entanglement across several kilometers of urban optical fibers, marking a significant advancement towards the development of a quantum internet. This achievement, which allows the linkage of information between objects regardless of distance, was highlighted by teams from the United States, China, and the Netherlands. They utilized the infrared spectrum compatible with optical fibers, achieving a breakthrough in connecting network parts through photons. This quantum internet could potentially enable highly secure cryptographic communications and connect quantum computers for enhanced computational power. The studies, which were published in Nature and on the preprint server arXiv, illustrate the transition from laboratory settings to practical urban environments, overcoming challenges such as signal loss and environmental interference. This work represents a critical move from theoretical exploration to real-world application, setting the stage for future networks that could span over 1,000 kilometers using entanglement swapping techniques.

STUDY UNCOVERS ROOTS OF CULTURAL DIVERSITY IN SMALL-SCALE SOCIETIES.

A recent study explores the origins of cultural diversity, particularly through the lens of institutional complexity within small-scale societies. Anthropologists have identified two main theories regarding the emergence of institutions. The first posits that institutions are established top-down by elites to control resources, power, and influence. The second theory suggests that institutions develop from the bottom-up, serving as collective solutions to adaptive challenges within societies. Utilizing Bayesian networks, the study analyzed the causal structure of institutional complexity across 172 small-scale societies in ethnohistoric western North America. The findings indicate that institutional complexity often arises from socioecological complexity, implying that institutions evolve as necessary frameworks for coordinating increasingly complex human-environment interactions. This study provides insight into how institutions may have historically formed to address coordination challenges in diverse environments. (Proceedings of the Royal Society B)

DUTCH WOMAN APPROVED FOR EUTHANASIA SPARKS EUROPEAN DEBATE.

Zoraya ter Beek, a 29-year-old Dutch woman, is set to undergo assisted dying due to her unbearable mental suffering, a decision that has sparked widespread debate in Europe. Ter Beek, who has suffered from chronic depression, anxiety, trauma, unspecified personality disorder, and autism since childhood, received approval for euthanasia after a rigorous three-and-a-half-year evaluation under the Netherlands’ 2002 law. Her case is notable as assisted dying for psychiatric conditions is rare in the Netherlands, with 138 cases in 2023 compared to two in 2010. Despite intensive treatments, including over 30 sessions of electroconvulsive therapy, Ter Beek found no relief, leading her to apply for euthanasia. The intense public reaction to her case, particularly after being covered by international media, added to her distress. Ter Beek remains determined, supported by strict Dutch regulations requiring candidates for assisted dying to be fully informed and competent. (The Guardian)

THIRD PLANET DISCOVERED IN KEPLER-47 BINARY-STAR SYSTEM.

Astronomers have identified a third planet in the Kepler-47 system, enhancing its status as the most intriguing binary-star system discovered. This addition, found using NASA’s Kepler space telescope data, situates the new Neptune-to-Saturn-sized planet, Kepler-47d, between two previously known planets. Kepler-47 remains the only known system with multiple planets orbiting dual stars. Initially undetected due to weak transit signals, Kepler-47d’s existence became apparent as its orbital plane’s alignment shifted, enhancing its transit visibility. Surprisingly, it is the largest planet in the system. This discovery, recently detailed in the Astronomical Journal by the San Diego State University team, adds crucial insights into the configuration and characteristics of such circumbinary planets. Notably, all three planets possess unusually low densities for their mild temperatures, a phenomenon rare outside of the typically hotter Jupiter-type exoplanets. This system, which could entirely fit within Earth’s orbit, is 3340 light-years away in the constellation Cygnus. (NASA)
