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.

AI-driven approach reveals hidden hazards of chemical mixtures in rivers

A new AI-driven approach identifies potentially harmful chemical substances in rivers by monitoring their effects on tiny water fleas, providing insights into complex mixtures and aquatic life. The study enables more comprehensive environmental monitoring and supports better-informed regulations for chemical discharge into waterways.

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.

Getting rehab earlier improves concussion outcomes, OHSU study suggests

A new study from Oregon Health & Science University found that people who receive physical therapy earlier after a concussion tend to have better balance control and reduced reaction times. This can lead to improved outcomes and reduced risk of re-injury. Early intervention may enable the brain to return to a more normal state, compens...

How to deal with narcissists at home and at work

Narcissists can be charming early on, but subtle signs indicate a need to get out of the relationship. Brunell discusses how researchers have learned to understand and cope with narcissists in various settings, including workplaces. Strategies for setting clear boundaries and managing situations are also shared.

A user manual for yeast’s genetic switches

Kobe University researchers discovered three gene regulation design principles to improve yeast promoter performance, reducing leakiness and increasing productivity. The study's findings have potential applications in hospitals and can be used to produce multiple biologics with a single yeast strain.
