The receptor that tells mosquitoes they are full after a blood meal lives in the rectum, not the brain. The finding reshapes understanding of mosquito feeding behavior and opens a potential new target for disrupting disease-carrying bites.

Low-income adults with diabetes who lost health insurance showed worse blood sugar control and needed more intensive medications within months, according to a study of community health center patients across 20 states - raising alarms as millions face Medicaid disenrollment.

A study of older adults at a socioeconomically vulnerable NYC emergency department found significant heat-health risks at temperatures below the city's 95F heat advisory trigger, suggesting tailored warning strategies are needed for at-risk populations.

Smokers who receive negative results on baseline low-dose CT screening still face substantially elevated long-term lung cancer risk - but the danger only becomes statistically significant after two years, suggesting current annual screening intervals could be safely extended.

A case-control study of low-income adults at community health centers found that sustained insurance loss was linked to worse blood sugar control, increased insulin use, and more acute diabetes complications - findings with urgency as Medicaid cuts loom.

Corals, jellyfish, and sea anemones share a common ancestor but have wildly different body shapes. A new study identifies three mechanical tissue properties - 'mechanotypes' - that predict and even control which form an organism takes.

Analysis of 55,200 ER visits across two NYC hospitals found that older adults in underserved communities face amplified heat-health risks starting at 90F - five degrees below the city's heat advisory threshold of 95F.

Embryonic mice heal wounds without scars by regenerating all skin cell types. Harvard researchers found the mechanism shuts off days after birth when fibroblasts recruit excess nerves -- and showed that blocking this signal restores scar-free healing.

Experiments with clonal raider ants show that nestmate recognition is far more flexible than assumed. Ants can learn to tolerate genetic outsiders through sustained contact, but even ants raised entirely among foreigners still accept their own genotype, suggesting an indelible sense of self.

A wheat immune receptor called WAI3 forms an octameric resistosome - the first eight-subunit immune complex found in plants. The structure, resolved by cryo-EM and published in Cell, reveals a distinct channel architecture that triggers calcium influx and requires plant-specific factors to function.

Sea urchin spines produce up to 100 millivolts when struck by water, thanks to their gradient porous internal structure. Researchers 3D-printed artificial versions that generate eight times the signal amplitude of non-gradient designs, creating self-powered underwater sensors.

Using miniature microscopes implanted in mice, McGill researchers found that the brain's internal compass - the head-direction system - remains structurally stable over months, even as the hippocampus constantly reshuffles. The stability may explain how memories persist despite shifting neural activity.

Michael Franklin, the computer scientist who co-founded the AMPLab at UC Berkeley and helped build UChicago's data science infrastructure, has been appointed Deputy Dean for Computational and Mathematical Sciences in the university's Physical Sciences Division.

A smartphone-based AI algorithm correctly identified occlusive heart attacks in 84% of cases among 1,490 patients who lacked the classic ST-elevation ECG sign, compared to 42% for standard diagnostic pathways, according to results presented at ESC Acute CardioVascular Care 2026.

Researchers found that the protein SHP suppresses cartilage-degrading enzymes MMP-3 and MMP-13 through the NF-kB pathway. SHP levels drop as osteoarthritis worsens, and restoring the protein via gene therapy reduced cartilage damage and pain in mouse models.

Sixteen years of road surveys across central South Africa reveal that half of 26 raptor and large terrestrial bird species have declined significantly, with the Secretarybird down 68%. Only three species showed clear increases, raising urgent conservation questions.

Scientists created the first lab-grown oesophagus that restored swallowing, developed functional muscle and nerves, and grew with the recipient animal over six months - all without immunosuppression. The advance targets children born with long-gap oesophageal atresia.

LazySlide, a new open-source tool published in Nature Methods, applies foundation AI models to whole-slide pathology images, letting researchers query tissue with plain language, link visual features to gene expression, and plug results into standard genomics workflows.

A Rutgers-led genomic study of 2.2 million people reveals that most genetic risk for addiction stems from genes governing reward processing, self-control, and risk-taking - not substance-specific pathways. Polygenic scores built on these shared pathways predicted risk across multiple substances.

AI foundation models trained on general time-series data from energy and transport sectors predicted river flows across 500+ U.S. basins nearly as well as models trained on decades of hydrological records. The approach could bring flood and drought forecasting to regions that lack monitoring infrastructure.

A scoping review by the University of Eastern Finland and Lakehead University finds Via Ferrata tourism growing fast but under-researched, particularly in North America. The study calls for collaboration between operators, land managers, and climbing organizations to guide sustainable development.

Swedish teenagers who played a fact-based migration simulation showed increased social understanding of immigrants, but their political attitudes remained largely unchanged. About 25% of players failed to reach their destination due to poverty, illness, or death - mirroring real-world barriers.

Nearly half of Norwegian adults surveyed use sleep apps, and most report learning more about their sleep. But people with insomnia symptoms are significantly more likely to experience increased worry and stress from the feedback, potentially worsening the problem they are trying to solve.

Ectotherms - fish, reptiles, invertebrates - do not physiologically adjust to daily temperature fluctuations, a Murdoch University meta-analysis of 26 studies finds. As climate change amplifies temperature variability, these animals may depend entirely on behavior and evolution to survive.

Queensland GPs report that compassionate care for patients seeking voluntary assisted dying is undermined by complex paperwork, absent Medicare rebates, and inconsistent training. With 90% of cases funneled through the public system, community-based doctors are being sidelined.
