Gene-edited babies may live shorter lives, analysis finds

Chinese scientist He Jiankui edited the genes of two babies to be resistant to HIV, provoking outrage. Now, a new genetic analysis shows why this was reckless.

  • The gene-editing technique CRISPR offers major benefits to humanity, but scientists don't believe the field is mature enough for widespread editing.
  • For this reason, when Chinese scientist He Jiankui edited the genes of two babies to be resistant to HIV, his work provoked outrage.
  • A new study of 400,000 genetic profiles reveals that He's genetic editing did indeed have an unintended consequence.

The "Düsseldorf patient": A third person may also be in HIV remission

Recently, "the London patient" became the second person in history to be cured of HIV. Now, "the Düsseldorf patient" appears to be the third, with the possibility of more on the way.

For second time ever a patient has been cured of HIV, scientists report

The promising news comes 12 years after the "Berlin patient" became the world's first person to be cured of the deadly virus.

  • The New York Times reports that a team of scientists plan to announce tomorrow that a patient in London has been effectively cured of HIV.
  • The cure reportedly was the result of a bone-marrow transplant that came with a genetic mutation that naturally blocks HIV from spreading throughout the body.
  • This approach isn't quite practical to implement on a large scale, but the knowledge gained from it will likely help scientists develop more scalable approaches.

  • The claim is unsubstantiated as of yet, but if true it would mark a historic moment in science and ethics.
  • The scientist claims to have edited a gene that controls whether someone can contract HIV.
  • Many say gene-editing is unethical, or that its technology is too premature to be used responsibly.
