I ricercatori affermano che l'aumento non è inevitabile ed è importante analizzare cosa ci sia dietro le differenze nelle tendenze dell'obesità

I ricercatori hanno scoperto che oltre 50 ore a settimana possono essere dannose per la salute, mentre responsabilità più leggere hanno un effetto positivo • Lo stress e le tensioni derivanti dall'assistenza a qualcuno per 50 ore o più a settimana portano a un "declino cognitivo accelerato" nelle persone di mezza età e negli anziani, mostra la ricerca. • Tuttavia, prestare assistenza solo per cinque o nove ore a settimana ha l'effetto opposto, migliorando così tanto la salute del cervello che i benefici durano fino alla vecchiaia.

• La ricerca rivela che paesi come gli Stati Uniti e il Messico, con orari di lavoro più lunghi, presentano tassi di obesità più elevati. • Chi lavora più ore ha maggiori probabilità di essere obeso e ridurre il tempo trascorso al lavoro potrebbe aiutare a mantenere il peso forma, suggerisce lo studio. • Una ricerca internazionale presentata all'European Congress on Obesity di Istanbul ha confrontato i modelli lavorativi e la prevalenza dell'obesità in 33 paesi OECD dal 1990 al 2022.

Finding would explain why type of stroke affecting about 35,000 a year in UK is not as responsive to some medicationThe cause of a type of stroke that affects about 35,000 people across the UK each year has been uncovered by researchers and may explain why some medications are ineffective as treatment.Lacunar strokes, which account for a quarter of all strokes in the UK, had been linked to the blockage of arteries in the brain by fatty deposits. However, a study published on Wednesday suggests they are not caused by blocked arteries but by the enlargement and widening of arteries in the brain. Continue reading...

Researchers found that TikTok’s For You pages prioritized pro-Republican content in New York, Texas and GeorgiaA study published Wednesday in the journal Nature finds that TikTok’s algorithm systematically prioritized pro-Republican content in three states leading up to the 2024 US elections.Researchers created hundreds of dummy accounts and conditioned them to mimic real users’ behavior by watching a set of videos either aligned with the US Democratic or Republican parties. Then, they tracked the videos TikTok recommended on these accounts’ For You pages, TikTok’s main feed. Continue reading...

Revelation comes after report commissioned by department released in response to charity’s FoI requestThe Ministry of Defence has no system for examining whether UK military action has killed or injured civilians in war, a study commissioned by the department has revealed.The MoD also “does not maintain a central register of civilian harm incidents or allegations” and, despite mass casualties caused by other countries, has concluded there is no need to do so because its existing mitigation is considered effective.

Reform UK is ‘doing something right when it comes to visibility’ on multiple AI systems, say researchersAI platforms are more likely to reference Nigel Farage than any other UK leader when prompted about British politics, according to an AI search analytics firm.“We are confident in saying that Reform are showing up significantly more than you would expect,” said Malte Landwehr, an expert at Peec AI, the firm that did the research. “So they’re doing something right when it comes to LLM [large language model] visibility.” Continue reading...

Louisiana’s cultural hotspot could be surrounded by Gulf of Mexico before end of this century, authors sayThe process of relocating people from New Orleans should start immediately as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded.Ongoing sea level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.

People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did notA common knee surgery for cartilage damage does not benefit patients and may lead to worse outcomes, a 10-year trial suggests.The study tracked outcomes for patients treated for a meniscus tear, who were given a partial meniscectomy, one of the most common orthopaedic surgeries. Their trajectories were compared with patients who had randomly been assigned to receive “sham surgery”, in which no procedure was carried out. Continue reading...

Researchers find ‘alarming’ effect on fertility across global species from simultaneous exposuresSimultaneous exposure to toxic chemicals and climate change’s impacts likely generates an additive or synergistic effect that increases reproductive harm, and may contribute to the broad global drop in fertility, new peer-reviewed research finds.The review of scientific literature considers how endocrine-disrupting chemicals, often found in plastic, coupled with climate change’s effects, such as heat stress, are each linked to reductions in fertility and fecundity across global species – including in humans, wildlife and invertebrates.

• A comprehensive analysis from the National Center for Atmospheric Research shows US carbon dioxide emissions fell 8.2% year-over-year in Q1 2026, driven primarily by renewable energy sources now supplying 34% of national electricity generation. • Solar and wind capacity additions reached record levels with 42 gigawatts of new renewable infrastructure installed in 2025, according to data released by the Department of Energy and independent research institutions. • Climate scientists attribute the acceleration partly to state-level climate policies and federal incentives from the 2024 Clean Energy Investment Act, though transportation and industrial sectors still require significant emission reductions.

• Researchers from Woods Hole Oceanographic Institution reported that Atlantic cod and other commercial fish populations have rebounded 34% over the past four years following strict catch quotas and marine protected areas implemented in 2022. • Population surveys conducted across 850,000 square kilometers of Atlantic waters show biomass increases in previously depleted stocks, with detailed findings presented at the American Fisheries Society conference on April 19. • The recovery demonstrates that science-based fisheries management can restore ecosystems within a decade, providing a model for international ocean conservation efforts.
