Scientists boost fingertip regrowth in breakthrough stem cell study
Scientists from the University of Warsaw have identified stem cells at the base of the nail as key drivers of fingertip regeneration and shown that activating a major cell-signalling pathway dramatically accelerates the regrowth of nails and bone after injury, according to a new study.

Epigenetic cancer 'fingerprints' can speed up and facilitate diagnosis
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.

Study finds DNA sequencing methods can miss key microbiome functions
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.

Alzheimer's and Parkinson's disease mechanisms are similar to prion diseases, says researcher
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.

Space radiation is 'no joke.' Astronauts may use water and clothes as emergency shielding
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 leave the brain awake even after a full night's sleep, scientists say
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.

Vaccination hesitancy driven more by psychology than science, expert says
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.
