Ever wondered why certain diseases seem to run in families, or how tiny changes in our DNA can lead to serious health conditions? Scientists have developed a powerful new tool that simultaneously analyzes both DNA and RNA within individual cells, offering unprecedented insight into how genetic variations contribute to disease. The Problem With Current Technology […]
Since the cells were discovered with the advent of the microscope in the late seventeenth century, scientists have tried hard to find out what is going on into them. An avalanche of techniques and technologies emerged over the course of decades slowly discovering important molecular features of the cellular world to our knowledge and our […]
In 1968, the Canadian psychologist from McGill University Ronald Melzack described pain as being multidimensional and complex, with sensory-discriminative, affective-motivational and cognitive-evaluative components . Such definition may be a hint as to why the biological meaning of pain has been an (to date) unceasing matter of debate since Aristotle, who thought pain is just a […]
Throughout the relentless struggle against cancer, conventional medicine has largely depended on aggressive methods of elimination—surgical removal, radiation, and chemotherapy—aimed at eradicating malignant cells before they can overwhelm the patient. While these approaches have proven effective in many cases, they often come at a steep cost, damaging healthy tissue and leaving patients vulnerable to recurrence […]
Author: Rohini Subrahmanyam is a PhD biologist turned science journalist. Insects that tuck away wings; a protist with an accordion-like neck — studying these clever creases may inspire foldable structures for drones As the microscopic, tear-shaped Lacrymaria olor swims around hunting for food, it does something remarkable: In a blink, the tiny protist extends its […]
T-cell acute lymphoblastic leukemia (T-ALL) is characterized by the accumulation of genetic lesions that induce differentiation arrest, survival and aberrant proliferation of immature T-cell progenitors . Although T-ALL prognosis has significantly improved due to intensive chemotherapy, relapses still occur in 20% of pediatric patients and 50% of adult patients, often with a dismal outcome. To […]
The Earth supports the only known life in the universe, all of it depending heavily on the presence of liquid water to facilitate chemical reactions. While single-celled life has existed almost as long as Earth itself, it took roughly three billion years for multicellular life to form. Human life has existed for less than one-10 […]

The light of someone’s life might not be just another person, but light in the literal sense. According to a recent study , every living system emits light without requiring external excitation due to a biological phenomenon known as ultraweak photon emission (UPE). In mice, UPE was linked to vitality as live mice emitted significantly […]
Author: Mohamady El-Gaby, Postdoctoral Neuroscientist, University of Oxford For decades, neuroscientists have developed mathematical frameworks to explain how brain activity drives behaviour in predictable, repetitive scenarios, such as while playing a game. These algorithms have not only described brain cell activity with remarkable precision but also helped develop artificial intelligence with superhuman achievements in specific […]
Author: María Rosa Pino Otín, Professor of Microbiology, Universidad San Jorge We often forget how wonderful it is that life exists, and what a special and unique phenomenon it is. As far as we know, ours is the only planet capable of supporting life, and it seems to have arisen in the form of something […]
