Enough family reference samples collected to identify at least 60% of disinterred USS Arizona crew membersThe United States government could move to disinter the remains of unidentified USS Arizona crew members who were killed in the surprise attack on Pearl Harbor in 1941 after the clinching of a key DNA-related milestone, officials recently announced.Before that announcement, officials determined enough family reference samples had been collected for comparison with DNA taken from remains – along with medical and dental records – for the individual identification of at least 60% of the battleship crew members to be disinterred, said a statement on Friday from the agency tasked with identifying US military personnel who are unaccounted for after past conflicts.

Hegde, Ph.D., stated 'DNA repair is one of the most fundamental processes in biology' and TDP43's role has major implications for these diseases. • The peer-reviewed study, published in Nucleic Acids Research on March 15, 2026, was funded by NIH's NINDS and National Institute on Aging.

Researchers from Cold Spring Harbor Laboratory (CSHL) and global collaborators identified over 2.3 million conserved non-coding sequences (CNSs) across 314 plant genomes from 284 species, using a new computational tool called Conservatory. These ancient 'DNA switches' originated before flowering plants diverged from non-flowering ancestors more than 400 million years ago, with some confirmed essential for developmental functions through genetic editing. The discovery provides a comprehensive atlas for plant biology, aiding crop breeders in addressing drought and food shortages by fine-tuning traits. CSHL's Zachary Lippman described it as 'a new window into the evolution of life across eons.'

Researchers from Cold Spring Harbor Laboratory (CSHL), Hebrew University, and Sainsbury Laboratory Cambridge University published a study in Science identifying over 2.3 million conserved non-coding sequences (CNSs) across 314 plant genomes from 284 species, some originating more than 400 million years ago before flowering plants diverged from non-flowering ancestors. The team developed a new computational tool called Conservatory to locate these ancient DNA 'switches' essential for plant development, with co-first author Anat Hendelman confirming their function through genetic editing. This comprehensive atlas includes dozens of crop species and wild ancestors, offering plant biologists and breeders tools to address drought and food shortages by fine-tuning traits.
