1+ mon, 2+ day ago   (784+ words) Artificial intelligence (AI) has been used to design functional viruses from scratch for the first time. The models generated around 700,000 potential genomes for new bacteriophages. From these, 302 candidates were selected for experimental testing, and DNA was synthesised for 285. Of these,…...

1+ mon, 3+ week ago   (235+ words) Early sperm cell precursors were obtained from human non-reproductive cells reprogrammed and then housed within a mouse system. Dr Kotaro Sasaki, senior author of the study and an associate professor of biomedical sciences at the University of Pennsylvania, told the…...

1+ mon, 3+ week ago   (261+ words) An experimental autologous T cell therapy has shown encouraging early results in children with aggressive brain tumours. Brain and spinal cord tumours are the second most common childhood cancers, accounting for more than 25 percent of paediatric cancer cases in the…...

2+ mon, 1+ week ago   (229+ words) Neurons can experience and repair DNA breaks during healthy brain development, particularly as they migrate through tightly packed regions of the developing brain. 'The developing brain appears to have evolved to tolerate and repair the neuronal damage efficiently,' said Professor…...

3+ mon, 1+ week ago   (152+ words) Blood stem cells can retain a long-term 'memory' of inflammatory events, which may help explain links between ageing, chronic disease and blood cancers. The researchers also observed similar genetic changes in immune cells derived from inflammatory memory stem cells, indicating…...

3+ mon, 3+ week ago   (252+ words) A simplified stem-cell-based embryo model (SCBEM) – a model of the early human embryo – has revealed a key mechanism required for blastocyst cavity formation. Dr Mo Li, an associate professor of biomedical sciences at KAUST who led this study, said: 'Early…...

4+ mon, 1+ week ago   (160+ words) Testicular tissue cryopreserved before puberty was shown to be able to produce viable sperm after being re-transplanted into the original patient, who is now an adult. The findings offer hope to men left infertile after childhood cancer treatments. Professor Rod…...
