Construction materials and household items are a part of a long-term carbon sink called the “technosphere”

Researchers estimate that human-made products store around 400 million tons of fossil carbon annually, equivalent to 9% of extracted fossil carbon. Recycling and increasing product lifetime can help reduce waste streams, while enacting policies to minimize landfill discharge is crucial.

Dark energy 'doesn’t exist' so can't be pushing 'lumpy' Universe apart – study

A team of physicists and astronomers found that the Universe is expanding in a more varied way than previously thought, making dark energy unnecessary. The new evidence supports the timescape model of cosmic expansion, which attributes differences in stretching light to calibration issues rather than dark energy.

Poor vascular health accelerates brain ageing

Researchers at Karolinska Institutet used AI to analyze brain images from 70-year-olds and found that factors like inflammation and high glucose levels are associated with an older-looking brain. A healthy lifestyle, on the other hand, was linked to brains with a younger appearance.

The aquaporin-4 inhibitor, N-(1,3,4-thiadiazol-2-yl)-3-pyridinecarboxamide, inhibits the glymphatic system

A study investigated the effects of N-(1,3,4-thiadiazol-2-yl)-3-pyridinecarboxamide (TGN-020), a selective AQP4 inhibitor, on glymphatic function. The results showed that acute inhibition of AQP4 significantly impaired glymphatic function without inducing short-term behavioral abnormalities in mice.

Neutrality has played a pivotal, but under-examined, role in international relations, new research shows

A new study analyzing 192 years of alliances, hostilities, and neutrality found that neutral ties were more prevalent than previously thought, playing a crucial role in global stability. The research introduces a new measure of relational structure called 'balance correlations,' which has profound implications for policymakers.

Modern AI systems have achieved Turing's vision, but not exactly how he hoped

Current energy-hungry transformer-based systems contrast with Turing's idea of machines that develop intelligence naturally, like human children. AI systems can now perform tasks exclusive to human intellect, such as generating coherent text and discussing abstract ideas, but with limitations on sustainability and societal impact

International norms for adult handgrip strength: A systematic review of data on 2.4 million adults aged 20 to 100+ years from 69 countries and regions

A systematic review of data on 2.4 million adults from 69 countries established international norms for handgrip strength, ranking strength into five categories: low, somewhat low, moderate, somewhat high, and high. The new framework enables clinicians to identify people at risk of poor health and track changes in strength over time.

One in five young Spaniards is an at-risk consumer of TikTok, spending more than two hours a day on the app, according to a study by UPF and the UOC

A recent study by UPF and UOC found that over half of young Spaniards spend more than an hour a day on TikTok, with girls exceeding the risk threshold for mental health problems. The app's passive consumption features and traditional gender roles in content preferences contribute to this issue.
