Hands are made by killing. The embryonic limb bud arrives as a paddle and fingers appear only once the tissue between them has received the ‘time to die’ memo. Pruning is not damage control. It is construction. The architecture is…
The genetic blueprint that aims to cure Wilson’s disease directly in the liver The scientific journal Nature recently published a news item by Heidi Ledford entitled “A first for CRISPR: powerful prime editing alters DNA directly in the human body,…
Japanese researchers have built a micronucleus test around T lymphocytes grown from human induced pluripotent stem cells, creating what they describe as a promising proof-of-principle alternative to the immortalized cell lines and fresh blood lymphocytes that dominate current in vitro…
A planetary-scale mining of public metagenomes collected 794 million CRISPR spacers and 1.18 billion virus and plasmid hits, revealing high spacer turnover and evidence that some targeting reflects viral genomes entering non-host cells.
A new review details how transparent, genetically similar zebrafish enable real-time study of melanogenesis and human pigmentation disorders.
The team first established general reaction conditions using single-factor experiments in symmetric PCR. Under these optimized conditions, the reaction contained 4.8 fmol/µL single-stranded DNA template, 20 µM of each dNTP, 80 nM of forward and reverse primers, 2 U of Taq DNA polymerase,…
A new review details how CRISPR gene editing, RNA interference, Wolbachia biocontrol and multi-omics surveillance are shifting dengue control from broad-spectrum insecticides toward precision-targeted vector and virus strategies.
A new study combines a computational model of CAG repeat instability with preclinical testing of an AAV-delivered microRNA that reduced MSH3 expression in primate striatal neurons by up to 94 percent and slowed somatic instability in Huntington's model mice.
For the L126S mutation, the team took a different approach, screening three cytosine base editors—BE4, YE1, and AID2S—in combination with guide RNAs in patient-derived iPSCs. The comparison showed that BE4 achieved the highest correction efficiency, reaching approximately 25% in the patient-derived cells and outperforming…
By Emily Leclerc, Waisman Science Writer It’s hard to predict how a small decision may make a major impact on a person’s life. For Albee Messing, VMD, PhD, Waisman investigator, the decision to pursue what others deemed a ridiculous idea…
CRISPR edits, delivery vectors, rare‑disease trials, and approvals.
