Editorial By Chris Hofstader

As you may have read in last week's edition of Science Briefs, we are experience serious technical difficulties with the Google Alerts we use to find the articles we publish in Blindness Briefs and in Science Briefs. We apologize for this problem and spent much of last week exploring alternatives. We've found some that look promising and will be testing one this week so we may be able to get back to our normal larger number of articles.


World Blind herald does not write the stories to which we link in Science Briefs, we gather them, curate them and bring them to our readers. We are not scientists ourselves and cannot guarantee the validity of the stories in this digest. We do, however, want to be very clear that you should not attempt any of the medical interventions mentioned in Science Briefs without first consulting a professional ophthalmologist and discussing it with them. Do not take medical advice from this or any other web site or podcast without first consulting a professional.
