Forskare från bland annat Sveriges Lantbruksuniversitet (SLU) har upptäckt varför vissa kvinnor, särskilt gravida, lockar mygg. De har identifierat 27 kemiska ämnen i doftprover, där oktenol spelar en nyckelroll. Upptäckten kan leda till bättre myggmedel.

Gravida kvinnor är särskilt lockande för myggor, enligt en ny studie. Forskare från Sveriges Lantbruksuniversitet (SLU) och andra institutioner har funnit att kvinnors attraktion på mygg påverkas av menscykeln och graviditet.

Med hjälp av doftprover från kvinnor identifierades 27 kemiska ämnen. Oktenol, även kallat svampalkohol, visade sig ha särskild betydelse och förekommer i större mängder hos gravida kvinnor.

Resultaten kan användas för att utveckla effektivare myggfällor och repellenter. "Så att vi exempelvis kan ta fram nya repellenter som stör dessa doftämnen", säger Rickard Ignell, professor vid SLU Alnarp, till P4 Värmland.

Scientists identify a rocket-fuel-like reaction that propels spinning iron crystals inside malaria parasites

19 mars 2026 Rapporterad av AI Bild genererad av AI Faktagranskad

University of Utah researchers report that iron-rich hemozoin crystals inside the malaria parasite Plasmodium falciparum move through the parasite’s digestive compartment because reactions involving hydrogen peroxide at the crystal surface generate chemical propulsion. The work, published in Proceedings of the National Academy of Sciences, links a long-observed phenomenon to peroxide chemistry and could point to new antimalarial drug strategies and ideas for engineered micro- and nanoscale devices.

Researchers model mosquito flight toward humans using visual and CO2 cues

Scientists from Georgia Tech and MIT have developed a mathematical model explaining how female Aedes aegypti mosquitoes navigate to humans. The study shows insects respond independently to dark visual cues and carbon dioxide rather than following each other. Findings could improve mosquito traps and disease control.

Hong Kong plans trial of infecting male mosquitoes next year

Hong Kong will trial a “mosquito-to-control-mosquito” strategy next year, infecting male mosquitoes with bacteria to prevent their offspring from maturing, following the city’s first local dengue fever case in over a year. Director of Food and Environmental Hygiene Donald Ng Man-kit announced the plan on Sunday, saying the government would consider stepping up measures amid a rapid mosquito population rise this month.

Study links modern living to higher oestrogen-recycling gut bacteria

13 april 2026 Rapporterad av AI

Gut bacteria that recycle oestrogens back into the bloodstream are far more abundant in people from industrialised societies than in hunter-gatherers and rural farmers, according to a new study. Researchers found up to seven times greater recycling capacity in urban populations. The findings raise questions about potential health impacts from elevated hormone levels.

Study finds half of Amazon insects at risk from heat stress

A new study of over 2,000 insect species reveals that many tropical insects, particularly in the Amazon, may struggle to adapt to rising temperatures. Researchers highlight limited heat tolerance in lowland species, potentially disrupting ecosystems. The findings, published in Nature, underscore vulnerabilities in regions with high biodiversity.

Study links high-residue produce to elevated pesticide levels

4 mars 2026 Rapporterad av AI

A new study from the Environmental Working Group finds that consuming more fruits and vegetables with higher pesticide residues, such as strawberries, spinach, and bell peppers, correlates with increased pesticide levels in urine. The research underscores diet as a primary exposure route while emphasizing the health benefits of produce. Findings highlight needs for better monitoring of cumulative pesticide effects.
