Scientists have developed a tumour classification system based on epigenetic changes that can distinguish nearly 50 types of cancer with high accuracy, a breakthrough that could eventually allow molecular testing to complement or partially replace conventional histopathology.
People perceived as physically attractive may have a lower risk of dying over the long term than those rated as unattractive, according to a new analysis of U.S. health data, although the researcher behind the study says the findings do not show that appearance itself determines health or longevity.
Genetically modified baker's yeast carrying a gene from tardigrades has performed well aboard the International Space Station (ISS), with preliminary results suggesting the added gene helps protect the organisms under the stressful conditions of low Earth orbit.
Important information about the gut microbiome may be lost before DNA sequencing data are even analysed, potentially affecting future efforts to diagnose disease, monitor antibiotic resistance and develop personalised medicine, according to a study by Polish and Estonian researchers.
Neurodegenerative diseases such as Alzheimer's and Parkinson's are not infectious in the conventional sense, but growing evidence suggests they share the same underlying biology as prion diseases, says Professor Beata Sikorska of the Medical University of Lodz.
Long-duration space missions face many hazards, but one of the least visible is cosmic radiation. Aleksandra Rutczyńska, an electronics engineer at the German Aerospace Center (DLR), develops radiation sensors flown on NASA's Artemis missions to the Moon.
Caffeine may shorten sleep or make it harder to fall asleep, but even when people appear to get enough sleep it can reduce the brain's deep restorative activity, according to researchers at the Medical University of Wrocław.
What does it actually mean for a battery to be fully charged? In the quantum world, the answer is less obvious than for an ordinary battery. Researchers from the University of Gdańsk have shown that in the smallest systems, it is not only the amount of usable energy that matters, but also the way it is internally organised.
Polish scientists will play a key role in a European Space Agency (ESA) mission to investigate how the solar wind interacts with Earth's magnetosphere, after the agency's Science Programme Committee recommended the Plasma Observatory as the next mission under its Voyage 2050 programme.
Vaccination hesitancy is driven less by medical knowledge gaps and more by psychological factors such as cognitive biases, trust, and communication style, according to a Polish psychologist who argues that how information is presented and who delivers it can be more influential than the scientific facts themselves.
