Study Reveals DNA Transfer Between Human Cells Raises Cancer Risks
Researchers led by Peter Ly at the Children’s Medical Center Research Institute in Dallas have discovered that damaged DNA can transfer between human cells through structures known as tunneling nanotubes, as reported in a study published on May 19 in Cell. This process raises concerns about the potential for harmful mutations to spread from cancer cells to healthy cells, complicating treatment options. The study highlights the need for further investigation into the frequency and implications of this DNA transfer in the context of cancer.
First Robotic Oesophagectomy Performed in Northern Ireland
William Duncan, a former engineer from Douglas Bridge in County Tyrone, became the first person in Northern Ireland to undergo robotic-assisted oesophagectomy for oesophageal cancer, a procedure he accepted without hesitation after his diagnosis in October 2025. This method, which offers advantages over traditional open surgery such as reduced pain and quicker recovery, allowed Duncan to be discharged after nine days, with only one night in ICU. He has since reported significant improvements in his recovery and encourages others to consider robotic surgery if offered.
Antarctic plants face rising fungal threats from warming
Research led by Kevin Newsham, a soil and plant ecologist with the British Antarctic Survey, indicates that Antarctic plants may increasingly face threats from fungal pathogens as global warming is projected to double their abundance in coastal soils by 2100. Analyses of over 50 soil samples from southern Chile to the Antarctic Peninsula reveal that higher temperatures correlate with increased diversity and abundance of pathogenic fungi, which could have significant impacts on the region's fragile plant communities.
AI Systems Enhance Drug Retargeting Success in Research
On May 20, 2026, Nature published two papers detailing the success of AI systems in drug retargeting tasks. Google's Co-Scientist, designed to assist researchers by integrating their judgments, and FutureHouse's system, which evaluates biological data from specific experiments, both generated hypotheses suggesting existing drugs for conditions such as acute myeloid leukemia and macular degeneration. These AI tools aim to enhance scientific research by identifying connections across diverse fields of study, addressing the challenges posed by the overwhelming volume of scientific literature.
