Mexican researchers want rules that distinguish gene-edited crops from GMOs. They launched a petition asking the government for evidence-based regulation while warning a March decree banning genetically modified maize could also affect gene editing.
Cell transplant may help heart after spinal cord injury
Researchers tested transplanting immature nerve cells into spinal cord injuries in rats. The transplants improved nerve control of circulation — stabilizing resting blood pressure and lowering heart rate — but hormonal responses after injury still rose.
New oral Listeria vaccine shows promise against colorectal cancer
Researchers report a modified oral vaccine made from Listeria that primes immune cells in the gut and limits tumor growth in mice. The vaccine worked best when combined with immune checkpoint inhibitors and caused few side effects.
