The heel prick test will now be accompanied by testing for spinal muscular atrophy (SMA), a rare muscle-wasting condition that can potentially lead to a child's death by the age of two.
The human maternal-fetal interface (MFI) is a transient hemi-allogeneic amalgam in which maternal decidual stromal cells (DSCs) support placental attachment, recruit immune cells and create a tolerogenic milieu for patterning fetal cytotrophoblast invasion.
The soft, flexible, robotic probe could dramatically improve safety during fetal surgeries, procedures in which physicians operate on a fetus before birth. Currently, doctors primarily rely on intermittent measurements of fetal heart rate using ultrasound imaging from outside the pregnant person's body. The new device, on the other hand, can be gently inserted through the same narrow port already used in fetal surgeries.
At a press conference in late 2025, federal officials made some big claims about leucovorin, a prescription drug usually reserved for people on cancer chemotherapy. "We're going to change the label to make it available [to children with autism spectrum disorder]," said Dr. Marty Makary, commissioner of the Food and Drug Administration. "Hundreds of thousands of kids, in my opinion, will benefit." The FDA still hasn't made that label change. Since Makary's remarks, though, more than 25,000 people have joined a Facebook group called Leucovorin for Autism. Most members appear to be parents seeking the drug for their autistic children.
In 2021, amid the COVID‑19 pandemic, Kristin Wall became pregnant with her second child. Her physician told her that little was known about the COVID-19 vaccine's safety and effectiveness in pregnant people. Observational data - collected from those vaccinated before they knew that they were pregnant - suggested that the vaccine was safe, so she could have it. Still, she'd have to weigh up the risks and benefits herself.
A trial in the US found that applying stem cells from the mother's placenta to her baby's spine while it was being repaired was safe and improved the child's mobility and quality of life. Dr Diana Farmer, who led the study, said it was conceivable that the experimental therapy could become the usual way that spina bifida is treated before babies are born.
