Researchers use CRISPR to edit DNA outside of the cell for the first time

Wilmington, DE, April 19, 2018 — Scientists at Christiana Care Health System’s Gene Editing Institute have developed a potentially breakthrough CRISPR gene-editing tool. It could allow researchers to take fragments of DNA extracted from human cells, put them into a test tube, and quickly and precisely engineer multiple changes to the genetic code, according to a new study published today in the CRISPR Journal.

Investigators at the Gene Editing Institute, which is part of the Helen F. Graham Cancer Center & Research Institute at Christiana Care, said their new “cell-free” CRISPR technology is the first CRISPR tool capable of making multiple edits to DNA samples “in vitro,” which means in a test tube or petri dish. The advance could have immediate value as a diagnostic tool, replicating the exact genetic mutations found in the tumors of individual cancer patients. Mutations that cause cancer to spread can differ from patient to patient, and being able to quickly identify the correct mutation affecting an individual patient can allow clinicians to implement a more targeted treatment strategy.

“With this new advance, we should be able to work with laboratory cultures and accomplish gene edits in less than a day, significantly reducing the time required for diagnostics compared to other CRISPR tools, and with much greater precision,” said Eric Kmiec, Ph.D., director of the Gene Editing Institute and principal author of the study. “This is particularly important for diagnostics linked to cancer care where time is critical.”

UK man’s super-gonorrhoea cured — but now two Australians have it

A UK man who caught what was dubbed the world’s “worst-ever” case of super-gonorrhoea has been cured, Public Health England (PHE) said — but two similar cases have been reported in Australia.

The unidentified heterosexual man, who had a partner in the UK, picked up the infection having sex with another woman in South-East Asia, PHE said.

Health officials said it was the first time the infection could not be cured with the regular treatment — a combination of antibiotics azithromycin and ceftriaxone.

What Will the Automated City of the Future Look Like?

Many large cities (Seoul, Tokyo, Shenzhen, Singapore, Dubai, London, San Francisco) serve as test beds for autonomous vehicle trials in a competitive race to develop “self-driving” cars. Automated ports and warehouses are also increasingly automated and robotized. Testing of delivery robots and drones is gathering pace beyond the warehouse gates. Automated control systems are monitoring, regulating and optimizing traffic flows. Automated vertical farms are innovating production of food in “non-agricultural” urban areas around the world. New mobile health technologies carry promise of healthcare “beyond the hospital.” Social robots in many guises – from police officers to restaurant waiters – are appearing in urban public and commercial spaces.


Tokyo, Singapore and Dubai are becoming prototype ‘robot cities,’ as governments start to see automation as the key to urban living.

Peptide-based biogenic dental product may cure cavities

Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities.

The research finding was first published in ACS Biomaterials Science and Engineering.

“Remineralization guided by peptides is a healthy alternative to current dental care,” said lead author Mehmet Sarikaya, professor of materials science and engineering and adjunct professor in the Department of Chemical Engineering and Department of Oral Health Sciences.
