Did you know that select resources are available in Spanish and Chinese on CBHD is committed to fostering a distinctly Christian conception of bioethics that is both academically rigorous and broadly accessible. Explore or share these timely bioethics resources with others. We look forward to providing translations in other languages including Portuguese in the future.  
Adderall Might Improve Your Test Scores-But So Could a Placebo
(New Scientist) — Students who take Adderall to improve their test scores may get a slight benefit, but it’s mainly a placebo effect. The drug Adderall is a combination of the stimulants amphetamine and dextroamphetamine, and is used to treat attention deficit hyperactivity disorder (ADHD). But it’s growing in popularity as a study drug in the US, where around a third of college students are thought to try using prescription stimulants for non-medical reasons. But does it work? …
First Double Hand Transplant Involving a Child Declared a Success
(The Guardian) — After almost 11 hours of surgery involving four teams of doctors, Zion Harvey had earned his place in medical history. The eight-year-old had become the first child in the world to receive two new hands in a procedure that seemed to herald a revolution in transplant medicine. Two years on, the sports-mad boy from Baltimore, Maryland, is enjoying the freedom and independence his new hands have given him. …
At a Growing Number of Schools, Sick Kids Can Take a Virtual Trip to the Doctor
(STAT News) — School nurses offer far more than just Band-Aids these days. As the prevalence of childhood conditions like asthma and diabetes have risen, nurses treat a wide range of problems. Still, only an estimated 40 percent of U.S. schools have a full-time nurse, according to the National Association of School Nurses. But now telemedicine — virtual doctor visits over video — is increasingly helping nurses do their jobs. Telemedicine programs are making inroads in schools, where a student referred to the nurse can be plopped in front of a screen and connected with a physician …
Prenatal Testing Spots Genetic Anomalies Linked to Miscarriage
(New Scientist) — A blood test can scan a fetus’s entire genome for chromosomal abnormalities at 10 weeks of pregnancy. An extension of the non-invasive prenatal test (NIPT) for Down’s syndrome, the test could identify pregnancies that should be monitored more closely as they are at a higher risk of miscarriage or complications. Chromosomal abnormalities occur in around 1 in 1000 births. The most common are Down’s syndrome, Edwards’ syndrome and Patau syndrome, which are caused by carrying an extra copy of a chromosome – chromosome 21 in the case of Down’s …
At Untested Stem Cell Clinics Advertise for Free!
(Wired) — Advocates of the therapy say that's just the cost of doing cutting-edge medicine. Except, any proof they have that it is effective comes from data collected on patients who pay thousands of dollars for the treatment. Usually people pay money for medicine after there's proof it works. In the last few years, some of these stem cell clinicians have begun posting large-scale studies on a government-run website …
Lights, Camera, CRISPR: Biologists Use Gene Editing to Store Movies in DNA
(Nature) — Internet users have a variety of format options in which to store their movies, and biologists have now joined the party. Researchers have used the microbial immune system CRISPR–Cas to encode a movie into the genome of the bacterium Escherichia coli. The technical achievement, reported on 12 July in Nature, is a step towards creating cellular recording systems that are capable of encoding a series of events, says Seth Shipman, a synthetic biologist at Harvard Medical School in Boston, Massachusetts.…
U.S. Expert Visits London Hospital to Examine Baby Charlie Gard
(Reuters) — A U.S doctor offering experimental treatment to a critically ill British baby visited the London hospital where he is being treated on Monday as part of a last-ditch attempt to persuade a judge to keep the boy's life support switched on. The parents of Charlie Gard, who has a rare genetic condition causing progressive muscle weakness and brain damage, have been fighting a legal battle to send him to the United States for the neurologist's experimental therapy …
Do Egg Donors Face Long-Term Risks?
(New York Times) — Ms. Wing’s cancer may have been totally unrelated to her egg donations. But given that Ms. Wing had been a health-conscious young woman with no family history of colon cancer or genes associated with this disease, Dr. Schneider wondered if the extensive hormone treatments her daughter had undergone might have stimulated growth of the cancer and if other egg donors might also be at risk. Alas, she soon discovered, it was impossible to know because no one was keeping track of the medical or psychological fate of egg donors. Once donors walk out the door, they are essentially lost to medical history …
