The finding has implications for conservation strategies and habitat fragmentation policies, suggesting current models of plant population dynamics may need revision.EN

Researchers combined two computational methods to dramatically reduce the expense of identifying useful genetic variants in wheat breeding programs. The approach catches rare genetic traits that existing cost-cutting methods miss, giving seed companies a faster, cheaper way to develop competitive crop varieties.EN

Royal jelly, a nutrient-rich substance produced by honeybees, may help lower blood sugar and cholesterol levels in people with metabolic disorders, according to a new scientific review. The finding could open a market for natural alternatives to costly pharmaceutical treatments, though researchers warn more human trials are needed before widespread clinical use.EN

A new analysis argues that artificial intelligence is fundamentally incapable of interpreting law or balancing competing rights—yet courts and governments are increasingly deploying it anyway. The gap between AI's perceived reliability and its actual limitations poses a hidden risk to legal systems and creates dangerous dependencies on private tech companies.EN

A new study of informal markets in Kenya reveals a dangerous gap: vendors and shoppers judge food safety by appearance and crowd size rather than actual contamination risks. This perception gap is driving a silent foodborne illness crisis across East Africa's informal food economy, which feeds millions daily but lacks basic safety standards.EN

Researchers have demonstrated that long-read DNA sequencing can accurately detect complex chromosomal rearrangements and genetic variants in a single test, matching or exceeding the accuracy of multiple specialized diagnostic approaches. The breakthrough suggests hospitals and diagnostic labs could consolidate dozens of separate genetic tests into one streamlined procedure, potentially cutting costs and turnaround times for patient diagnosis.EN

Researchers have completed the first comprehensive classification of Paramollugo, a widespread but little-known plant genus, identifying 11 species and clarifying their evolutionary relationships across three continents. The work matters for biodiversity conservation efforts and may inform research into the plant's potential agricultural or pharmaceutical properties.EN

Researchers discovered that inherited advantage in nature doesn't always come from superior abilities—it can result from simple geography. In collared flycatchers, access to food resources is highly heritable, yet birds don't inherit the skills to acquire those resources. This challenges how evolutionary biologists predict adaptation and has implications for understanding inequality in any competitive system.EN

Researchers identified multiple strains of Pantoea bacteria—a family of emerging pathogens resistant to multiple antibiotics—in sepsis patients across Ethiopian hospitals. The finding matters because sepsis kills hundreds of thousands globally each year, and these antibiotic-resistant variants could complicate treatment and drive healthcare costs higher.EN

Inga Hedberg, who died at 96, spent six decades cataloging African plant species alongside her husband—work that created foundational data for conservation, agriculture, and drug discovery efforts. Her Flora of Ethiopia and Eritrea remains a critical reference for researchers and policymakers developing strategies around food security and biodiversity protection across the continent.EN

A 20-year analysis of fungal research reveals that high-impact journals are poor predictors of scientific breakthroughs in mycology. Low-profile publications account for substantial portions of new species discoveries, suggesting that current metrics used to evaluate researcher performance and allocate funding may be fundamentally flawed.EN

Researchers have finally analyzed a 275-year-old feeding experiment by botanist Carl Linnaeus, finding that goats and sheep eat far more plant species than cows or pigs. The findings could inform livestock management, feed sourcing, and land-use decisions for agricultural operations managing diverse herds.EN

Researchers discovered that waxy hydrocarbon coatings on cyanobacteria membranes protect photosynthesis from light damage by regulating lipid composition. The finding could unlock new ways to engineer more resilient crops and algae-based biofuels—industries betting on photosynthetic organisms to solve food and energy challenges.EN

Researchers have resolved a long-standing puzzle about how three major fungal groups evolved alongside plants, establishing the first clear family tree for organisms critical to global agriculture. The findings could guide efforts to harness these fungi to improve crop resilience and reduce dependency on chemical fertilizers—a significant market opportunity as farming faces mounting pressure from climate change.EN

Researchers discovered that arbuscular mycorrhizal fungi—organisms critical to crop health—contain far more genetic variation within individual cells than previously thought. The finding matters for agriculture and biotech: understanding this internal diversity could improve breeding programs and help predict how these symbiotic fungi respond to environmental stress and disease.EN

Scientists have identified how a gene copied onto the Y chromosome allows male seed beetles to grow larger than females — evidence that sex chromosomes actively drive physical differences between males and females, not just carry reproductive traits. The finding could reshape understanding of sex-linked traits across species and inform research into growth disorders and sexual development in humans.EN

Scientists have identified a 470-million-year-old snail-like creature preserved in Estonian rock with unusually clear muscle markings, reshaping our understanding of mollusk evolution. The discovery challenges previous assumptions about which ancient creatures were the earliest gastropods, offering paleontologists a clearer picture of how this economically important animal lineage emerged.EN

When dry soil gets wet again, microbes rapidly consume trehalose—a stored sugar—and release it as CO2 rather than using it for growth. The finding explains a poorly understood carbon loss mechanism in soils that has implications for agriculture, carbon sequestration efforts, and climate models.EN

Researchers discovered that liverworts maintain unusually compact, stable genomes by actively suppressing the DNA duplications and transposable elements that cause genome bloat in other plants. The findings could inform crop breeding strategies and reveal fundamental mechanisms controlling genome evolution—with implications for agricultural efficiency and synthetic biology applications.EN

A study of a model fungus reveals it consistently avoids self-mating despite producing healthier offspring that way—defying evolutionary logic. The finding challenges assumptions about how organisms optimize reproduction and could reshape understanding of sexual selection in microorganisms, with implications for fields from agriculture to synthetic biology.EN

A new study challenges decades of assumptions about how polyploid crops develop, showing that hybridization—not whole-genome duplication—controls gene behavior in new plant varieties. The finding could reshape breeding strategies for creating more resilient crops as agriculture faces climate pressures.EN

A new special issue examines how to rigorously study processes unfolding over centuries—from social evolution to environmental shifts. The work matters for organizations planning strategy across decades: it offers tested methodologies for understanding slow-moving trends that shape markets, regulations, and societies.EN

**Brunalger ger nya möjligheter för biomaterial i livsmedel** Forskare vid Luleå tekniska universitet utvecklar funktionella biomaterial direkt från brunalgers naturliga struktur utan kemisk omarbetning. Genom att bevara alginernatets och cellulosan inneboende arkitektur skapar de hydrogeler med upp till 3600 % vätskeabsorption och 93 % porositet — relevant för förpacknings- och konserveringslösningar. Materialet framställs genom mekanisk fiberisering och 3D-printing eller frystorkning. Cytokompatibilitetstestning visar 73 % cellviabilitet vid normal koncentration, dock sjunkande effekt vid högre doser, vilket signalerar behov av dosoptimering för biomedicinskapsyk. För livsmedelsproducenter öppnar detta vägen till miljösnål förpackning från ett lokalt råmaterial. Regelramverket för biomaterial i direktkontakt med livsmedel kräver dock ytterligare validering före kommersialisering — en process som sannolikt tar 2–3 år. Brunalger från havsbotten blir potentiell konkurrens till syntetiska lösningar.
