Ever since scientists created the powerful gene-editing technique CRISPR, they have braced for the day when it would be used to produce a genetically altered human being. Now, the moment they feared may have come. What’s likely to happen next?

The children granted wishes were substantially less likely to visit the emergency department or to have an unplanned hospital admission within two years as compared with children who hadn’t received wishes. (Researchers matched the children’s personal and disease characteristics in the study.)

“My hypothesis is that these kids, when they come back, are more engaged with their families and medical providers, and perhaps they’re more adherent to their treatment plan,” says the study’s lead author Dr. Anup D. Patel, section chief of neurology at Nationwide Children’s Hospital and an associate professor of pediatrics at Ohio State University College of Medicine in Columbus.

Nearly 70,000 children end up in emergency rooms every year after experiencing adverse reactions to antibiotic drugs, according to an analysis by the Centers for Disease Control and Prevention (CDC) published in August in the Journal of the Pediatric Infectious Diseases Society.

About 74 million antibiotic prescriptions are doled out to kids each year, the study notes, and past research has indicated that at least one-third of these pediatric antibiotic prescriptions are unnecessary.

Results from a new study may lead to approval of what could be the first drug that ameliorates potentially deadly reactions in children with severe peanut allergies.

For many children with autism spectrum disorder (ASD), recognizing and responding to eye contact, body language, and tone of voice is a major challenge. Improving those social skills can take lots of work—putting a strain on caregivers with limited time, resources, and money for therapy. Now, a study shows that just 30 days with an in-home robot that provides social feedback can dramatically improve a child’s interactions with others.

Dr Bernadka Dubicka, who chairs the child and adolescent faculty at the Royal College of Psychiatrists, said: “Currently only one in four children and young people are treated for their mental health problems. “The fact that prescriptions for antidepressants are rising could reflect a slow but steady move towards treating everyone who is unwell.

The 4-year-old boy fancied himself a real-life superhero, wearing a blue T-shirt with photographs of his 4-month-old twin brothers, who were born with a rare immunodeficiency disease. Michael’s little brothers —  Santino, “Sonny,” and Giovanni, “Gio” — needed a bone-marrow transplant, and when his parents told him that he was a donor match, Michael told them that he wanted to save his brothers and would give them some of his.

It’s a compelling narrative: A parent learns that his or her child has a fatal disease with no cure, and, though not a scientist, embarks on a quest to find some treatment. Such stories have played out in the plotlines of films such as Lorenzo’s Oil and Extraordinary Measures, on national morning shows and local news segments, and on crowdfunding pages to drum up support for the cause.

Alfie, admitted to Alder Hey Hospital in December 2016, was diagnosed with a neurodegenerative disease associated with severe epilepsy and has been in a semivegetative state for more than a year. During that time, he has been kept alive by artificial ventilation in the critical care unit.
