A comprehensive review of breast cancer risk models in women with a family history found that none are highly accurate at identifying which women will develop the disease. The BOADICEA model showed balanced performance, while others had significant limitations, emphasizing the need for continued improvement.
Researchers investigated the interplay between host and gut microbiota in selenium metabolism, finding that gut microbiota transform selenium into metabolites influencing utilization, detoxification, and excretion. The study also revealed that Se intake affects bacterial diversity and that gut microbes produce unique selenometabolites.
A new quantum chemistry method predicts the behavior of molecules under light with lower computational cost, enabling the study of larger systems and complex reaction pathways. This breakthrough advances the discovery of next-generation materials and deepens understanding of molecular behavior under light.
The use of weight loss medications like semaglutide and tirzepatide could deepen existing health inequalities if patients lack access to nutrition advice, healthy food, and ongoing healthcare support. Researchers warn that poorer patients may face barriers to using these treatments safely and maintaining health improvements over time.
The SMArT platform achieves near-pure selection of correctly edited blood stem cells while reducing dangerous genomic alterations. The innovative strategy enables enrichment of cells with targeted integration to 100% purity.
Researchers have developed a new device called Neuropixels Opto that can record and manipulate neuron activity in the brain. The device, published in Nature Methods, integrates electrophysiology and optogenetics to provide unprecedented insight into neural circuits and neurological conditions such as Alzheimer's disease and schizophrenia.
Researchers at EPFL have discovered a way to generate and screen large libraries of synthetic cyclic peptides that can both enter cells and block disease-related protein interactions. This breakthrough could broaden access to previously difficult targets for drug development, enabling the creation of orally available peptide drugs.
A team of astronomers has identified a rare stellar system that provides a unique natural laboratory to study extreme physics. The system, called ASKAP J1745−5051, consists of a white dwarf and a red dwarf star, producing powerful bursts of radio waves and X-rays.
Regular physical activity improves blood pressure, insulin sensitivity, cholesterol levels, and cardiorespiratory fitness in adults with overweight or obesity. Exercise is essential for maintaining weight loss and supporting overall heart and metabolic health.
A UK study found that middle-aged and older adults with higher autistic traits are more likely to report worsening anxiety as they age. Researchers identified three distinct groups based on their anxiety responses over eight years, highlighting the importance of early identification and tailored support for this vulnerable minority.
A secondary analysis of the digital insomnia therapy somnovia identifies reducing hyperarousal as its primary mechanism of action for treating chronic insomnia. This process is linked to numerous other mental health conditions, suggesting positive effects beyond just sleep disorders.
A renowned conservation program, launched in 1996, has failed to maintain its success in promoting wolverine population growth. Despite initial promising results, documented numbers have fallen significantly in northern strongholds, with government funds frozen for two decades.
Researchers have discovered a crystal material with extreme optical anisotropy, which can bend light in highly directional nanoscale rays. This property makes it ideal for miniaturizing high-performance optical hardware, including smart contact lenses and ultrathin AR glasses.
Researchers have developed an approach to prevent transmission of E. coli K1 bacteria to newborns, reducing the risk of meningitis by up to 80%. The treatment involves an oral vaccination that weakens the bacteria, followed by a harmless probiotic bacterium that competes with the weakened pathogen for food.
A team of researchers developed a method for creating realistic virtual tomato farms that automatically generate data for training agricultural AI systems. The approach uses advanced reconstruction methods and Unreal Engine 5 software to reproduce lighting, textures, and geometry, resulting in highly accurate object detection models.
Researchers have demonstrated a record-breaking 450 terabits per second optical transmission over a field-deployed legacy fiber in London, UK. The achievement uses new optical-amplifier technologies to support ultra-wideband signals, exceeding previous records and unlocking previously untapped capacity in standard optical fibers.
A new study by the Potsdam Institute for Climate Impact Research finds that the EU's carbon border adjustment mechanism (CBAM) can trigger other countries to adopt carbon pricing. This could lead to a significant reduction in CO2 emissions, with up to 73% more emissions avoided compared to current policies.
