  • Postrach małych i dużych, czyli garść o wirusie ZIKA

    By Marta Koblańska, as a translator, the translation based on ,,Nature” published research, January 2021, edited April 30, 2026, photo: AI-generated neural structure, Pixabay Zakażenie wirusem Zika (ZIKV) kobiety w ciąży może skutkować samoistną utratą ciąży, koniecznością aborcji, urodzeniem martwego dziecka, zgonem dziecka po narodzinach albo wadami wrodzonymi, głównie mikrocefalią (małogłowiem) u dziecka. Ta ostatnia…

  • A new approach to correcting errors. The way to modify the body blocks

    By Marta Koblańska, January 29, 2026, 16:00 Poland’s time. The Author of the photo: Ruijin Ji, Cell Reports  By modifying the conversion of purine bases that constitute a body’s template for growth and health, it may be possible to cure the most damaging illnesses, according to scientists in China. China is well-known for its farsighted…

  • Carrying a disease. How a gene can alter the sense of life

    By Marta Koblańska, January 2, 2026, 15:00 Poland’s time, Photo: double helix of DNA, Pixabay The lower the frequency of a disease-inducing gene variant, the larger the absolute effect in size; however, the growth is slower, according to the third most-cited study in 2024, published in Cell Genomics. The third most-cited study of 2024, with…

  • Stamps of humans: Where do they originate from?

    By Marta Koblańska, 16.12.2025, 12:00 Poland’s time, photo: DNA clash, Pixabay Conflicting genes enable acquiring adaptive morphs – according to a new study from Denmark and China recently published in,, Cell Press”. The human body comprises chemical, molecular, and morphological levels. Each of them has to work properly to maintain functionality and efficiency, and all…

  • How to make cancer dead in the body? Blood holds the key

    by Marta Koblańska, 27.08.2025, 16:47 Poland’s time. Photo: CTC in cancer, Circulating tumor cells in the metastatic cascade (spreading fast), Cancer Cell Circulating tumor cells in the bloodstream may be crucial for therapies and preventing new metastases in the body. However, success depends on their molecular structure. Circulating tumor cells (CTCs) are utilized to assess…

  • Science-confirmed reason to welcome guests

    By Marta Koblańska, August 22, 2025, 12:20 Poland’s time, photo: DNA’s clash, Placidplace, Pixabay The risk for a population to become extinct increases along with extended and intensified inbreeding, American scientists claim. Simultaneously, genetic diversity may be taken as an advantage. In ancient Egypt, inbreeding was seen as a method to preserve the population’s exceptional…

  • Is male or female a weak sex?

    by Marta Koblańska, July 26, 18:10, Photo: DNA, author TyliJura, Pixabay The relationship between the male sex code and the female body is unclear. However, a virtual degradation leads to a selective advantage, though this may be misleading, according to a study conducted by Austrian scientists. Sex determinants, namely the X and Y chromosomes, emerge…

  • Rzeczywiste i iluzoryczne kontrowersje wokół ciąży

    Autor tekstu: Marta Koblańska, 30 maja 2025. Zdjęcie: Zapłodnienie. Licencja TBIT, Pixabay Im cięższa jest wada genetyczna zarodka i późniejszego płodu, tym szybciej jest on eliminowany z organizmu kobiety. Lżejsze wady z reguły pozwalają na donoszenie ciąży, choć nie oznacza to, że dziecko przeżyje po urodzeniu – mówią eksperci z zakresu ginekologii i położnictwa oraz neonatologii.…

  • Why are genes less similar better for studying diseases?

    Photo: Baboon, Clker-Free-Vector-Images, Pixabay Baboons show greater resilience to diseases despite their diverse genome, whereas humans, with a singular set of chromosomes, exhibit increased susceptibility – according to a new study published in ,,Cell Genomics”.  Genetic variations differ in humans as a whole body or within the body in certain tissues. Genetic variation, simplifying, is the number of chromosomal…

  • When and why might the genetic code change? Groundbreaking research addresses these questions.

Can we live outside…

  • Why does mitochondrial disruption cost so much?

    Photo: Mitochondrium, SkieTheAce, Pixabay Does evolution know the paths of the past and future? That’s possible according to new research published in ,,Cell”. How? By tracking the transport of signals and nutrients inside a cell. The mitochondrion is a cell organelle with a separate from the cell nucleus genetic material inherited only from a female…

  • What makes aging more friendly? X chromosome

    Photo: Blueberries, congerdesign, Pixabay The later activation of the X chromosome may enhance cognitive function, which could partly explain why women tend to have longer lifespans. Each of us inherits our genetic background from our parents, grandparents, and even distant ancestors that we may have forgotten. Humans have 23 pairs of chromosomes, with one set…

  • Paradox of evolution. What can capture and unleash us from Earth?

    Photo: Molecules, wastedgeneration, Pixabay A tiny insertion of a highly charged, binding potential helix into the space of RNA after the prokaryote code was lost or removed could change the direction of life’s evolution. RNA is a single-strand of ribonucleic acid, which is more primordial to DNA built with two strands and slightly different bases.…

  • Does lack of oxygen in body cells trigger cancer?

    Photo: Comparison of the performance of the 70 published hypoxia signatures using the IQM in 104 cancer cell lines, University of Oxford, Matteo Di Giovannantonio, Fiona Hartley Too high demand for oxygen in the body may signal cancer. A decrease of oxygen in tissues’ micro-environment shifts metabolic pathways. Oxygen is a substance without which there would have…

  • Human traits. Are they arriving on time?

    By Marta Koblańska, January 29, 16:55, Photo: public domain Pixabay Is it possible to catch differences in human genome visible and invisible expression? Modern technologies enable so. And what’s more they can trace our past to millions of years back. Natural selection which is an ongoing process of passing traits from one generation to the…

  • The key for domestication. Humans’ capability or plant’s domesticability?

    Oryginal date of publishing January 15/2025, By Marta Koblańska, Photo: Pixabay Just 15 edible plants provide us 90 percent of calories while a few hundred have been finally domesticated of the thousands of them. Why? The answer might be eligibility for domestication or humans’ limited ability. As state scientists, University of Southampton, UK in the…

  • Global warming is changing our DNA. But it may be an advantage

    Photo: Pete Linforth Evolutionary response to climate change accelerated in the past 20 years. But, as Spanish scientists claim, the fact may help in adaptation to ongoing transformation. Global warming becomes a new reality which impacts life on Earth. Now no one is questioning the ecological changes it brings and more and more often they…
