The findings could enable genetic screening to identify at-risk individuals early and point toward new drug targets for a cancer with historically poor survival rates.EN

Researchers analyzed 1.52 million people to identify genes whose mutations are so deadly in the womb that they almost never appear in living populations. The findings could reshape genetic screening programs, drug development priorities, and how insurers and regulators assess genetic risk in prenatal testing and population health initiatives.EN

Researchers found that a receptor called GPR15 is abnormally active in people who suffer early heart attacks, and its activity may explain why smoking dramatically increases risk. The discovery could lead to blood tests that identify high-risk patients before symptoms appear and point toward new drug targets for preventing heart disease.EN

Researchers analyzed 91 Bronze Age genomes from Poland and Ukraine, discovering that Middle Bronze Age populations underwent a genetic shift incorporating hunter-gatherer ancestry and organized into patrilineal family groups. The finding reshapes how historians understand social organization in prehistoric Europe and demonstrates how genetic analysis can reveal the drivers—biological or cultural—behind dramatic shifts in ancient burial practices and settlement patterns.EN

Researchers have created a 3D human tissue model that shows how Lyme disease spirochetes breach the blood-brain barrier and cause neurological infection. The finding exposes critical differences between bacterial strains, potentially opening pathways for better diagnostics and treatments for a disease affecting hundreds of thousands annually in Europe and North America.EN

Scientists discovered that some asexual animals maintain genetic diversity through an unexpected mating mechanism—recombinant chromosomes stick together instead of separating. The finding reshapes understanding of how organisms without sexual reproduction survive evolutionary pressures, with implications for genetic engineering, agriculture, and disease control in organisms that reproduce without mates.EN

Researchers identified a patient carrying two uncommon genetic variants in complement genes that severely impair immune function, yet current treatments failed to restore it. The finding suggests some autoimmune diseases may stem from complex genetic interactions rather than single defects, potentially opening new diagnostic and therapeutic approaches for difficult-to-treat patients.EN

Researchers have mapped how bacteria, algae, and fungi can convert agricultural waste into protein-rich feed for livestock, potentially freeing billions of acres currently dedicated to crop production. The technology is already commercialized but new methods could make it cheaper and more sustainable—a shift that could reshape how farms operate and compete globally.EN

Researchers decoded the complete genomes of two Scaevola species that have thrived far beyond their original Australian habitat—one becoming invasive, the other facing extinction. The findings reveal how plants copy and expand specific genes to handle extreme stress, offering insights for agriculture and conservation efforts in coastal regions worldwide.EN

Researchers crowdsourced machine learning models from 1,175 teams worldwide to automatically identify tissue structures in microscopy images across different organs. The winning approach could accelerate drug development and disease research by enabling faster, standardized analysis of human tissue samples at scale.EN

A major analysis of 21 clinical trials shows that therapies preserving the pancreas's insulin-producing cells can lower blood sugar levels and reduce insulin dependence in newly diagnosed type 1 diabetes patients. The finding could reshape treatment strategies and reduce long-term healthcare costs for the estimated 1.6 million Americans with type 1 diabetes.EN

Researchers identified three families of beneficial fungi living inside Dutch elm trees that correlate with resistance to a devastating pathogen. The discovery could guide breeding programs and forest management strategies worth millions in timber and urban ecosystem preservation.EN

Hjärnan integrerar sinnesintryck från olika modaliteter genom att bygga upp så kallade cross-modal invarianter — representationer som fungerar oberoende av sammanhang. Denna mekanisk förmåga förklarar hur vi kan uppfatta ljud och känsel tillsammans även när de inte inträffar samtidigt, vilket varit kritiskt för överlevnad. Forskare vid École Normale Supérieure i Paris och Lunds universitet visar att unimodala invarianter — baserade på kinetiska strukturer — uppstår i nervsystemet före kortex och har förankring i fysik. Cross-modala invarianter däremot lärs individuellt och domineras av kortexen, vilket gör dem mycket variabler mellan personer och utbredda i kortikala representationer. Detta förklarar varför hjärnans flerkanalintegration varit svår att kartlägga. Insikterna får tillämpningar inom gränssnittskonstruktion och virtual reality, där förståelse av dessa mekanismer möjliggör mer intuitiva människa-maskin-interaktioner.

Forskargruppen publicerar en kartläggning av genomets radella arkitektur på allelspecifik nivå i möss — ett första steg för att förstå hur tredimensionell kromosomorganisation reglerar genexpression och cellfunktion. Arbetet kombinerar högupplösta kromosomkonformationstekniker med genetisk analys för att avslöja hur varje kromosomkopia är positionerad i cellkärnan och hur denna ordning skiljer sig mellan alleler. Magda Bienko och hennes grupp vid Human Technopole (Italien) samarbetade med Science for Life Laboratory och Karolinska Institutet samt Francis Crick Institute. Insikten att genomarkitektur är alleldifferentierad öppnar nya vägar för att förstå epigenetisk reglering och potentiellt identifiera strukturella varianter som påverkar sjukdom. För bolagsbyggare inom genteknologi och diagnostik är resultatet relevant för utveckling av nästa generations screeningmetoder och målidentifiering baserat på tredimensionell genomstruktur snarare än sekvens enbart.

Researchers found that when bacteria face infection-like stresses, they decouple their genetic instructions from actual protein production—making it harder to predict how pathogens will behave. This discovery in three major human pathogens could reshape how companies develop antibiotics and diagnostics by revealing that traditional gene-expression data alone won't forecast bacterial survival tactics.EN
