A new study led by researchers at Harvard T.H. Chan School of Public Health and Mass General Brigham reveals that stillbirth rates in the U.S. are higher than previously reported, with over 1 in 150 births resulting in stillbirth, particularly affecting low-income areas. The study highlights that while many stillbirths occur with identifiable clinical risk factors, a significant portion, especially at 40+ weeks gestation, occur without any known risks, emphasizing the need for improved prevention and risk prediction strategies.

The article presents a preprint hosted on the Open Science Framework, focusing on social science research. It aims to contribute to the scholarly conversation by providing preliminary findings or methodologies for peer review and discussion within the academic community.

The article from Cambridge University Press appears to be related to nonmonotonic logic, a type of logic that allows for the introduction of new information that can change prior conclusions. However, the content primarily consists of navigational links and institutional access details rather than substantive information on the topic itself.

Researchers from the University of Cambridge and Meta have found that for average-sized living rooms, ultra-HD televisions (4K and 8K) provide no noticeable benefit over 2K screens. Their study reveals that the human eye's resolution limit means higher pixel counts are often imperceptible, leading to the conclusion that upgrading to higher resolution screens may be unnecessary for most viewers.

Researchers at Mass General Brigham have discovered how brain activity, energy use, and blood flow change as people transition from wakefulness to sleep, particularly during non-rapid eye movement (NREM) sleep. Their findings reveal that while sensory areas remain active, cognitive regions quiet down, which may help the brain remain responsive to external stimuli during sleep. This research offers new insights into the mechanisms behind neurological and sleep-related diseases.

Llion Jones, co-author of the transformer architecture, expressed concern at the TED AI conference that the AI research field has become too focused on a single approach, limiting creativity and innovation. He announced his decision to move away from transformers, emphasizing the need for exploration of new ideas and warning that current pressures may hinder groundbreaking advances in AI technology.

Researchers at the University of Otago have developed algorithms that enable smartwatches to achieve centimetre-level positioning accuracy, a significant advancement for wearable technology. This breakthrough was made possible through collaboration with Google and the Chinese Academy of Sciences, utilizing the Google GnssLogger app and signals from multiple global navigation satellite systems. The results were published in the journal GPS Solutions, highlighting the potential for high-precision tracking in everyday devices.

The document appears to be a PDF file, likely containing a working paper from the National Bureau of Economic Research (NBER) on a specific economic topic. However, due to the nature of the content being unreadable in its current format, a detailed summary of the findings or arguments presented in the paper cannot be provided.
