While we wait for Neuralink to present the progress it’s made over the last couple of years in brain-computer interface technology, the New York Times has already published information from an early briefing and it’s stuff that’s straight out of science fiction. The Elon Musk-backed company claims its “sewing machine-like” robot can implant threads deep into a human brain. Continue reading Elon Musk’s Neuralink hopes to put sensors in human brains next year
LAST MONTH THE Food and Drug Administration sent out an emergency alert: Two people who had undergone fecal transplants developed multi-drug-resistant infections from bacteria in the stool they were given, and one died. Continue reading THE DEATH OF A PATIENT AND THE FUTURE OF FECAL TRANSPLANTS
Developing an H.I.V. vaccine has been a perplexing challenge that has mostly resulted in failure, but now scientists have identified key factors that allow some people to naturally suppress the H.I.V. virus—work that could lead to better vaccines to both treat and prevent the infection. Researchers believe they have identified crucial points on the virus’s surface where the immune system can successfully attack H.I.V.
Bioengineers are one step closer to 3D printing organs and tissues. A team led by Rice University and the University of Washington have developed a tool to 3D print complex and “exquisitely entangled” vascular networks. These mimic the body’s natural passageways for blood, air, lymph and other fluids, and they will be essential for artificial organs.
Around five years ago, a pregnant woman in Australia went in for her six-week ultrasound and was told she would be having twins. Her scan showed that the fetuses were sharing a single placenta, indicating that they were identical. But when the woman came in for a follow-up ultrasound at 14 weeks, it was discovered that she was carrying a boy and a girl—something that is impossible in identical twins. Continue reading Doctors Identify Very Rare ‘Semi-Identical’ Twins
A few years ago, emergency radiologist Bharti Khurana examined scans from a patient with nasal bone fractures—an old one, on one side of her nose, and a new one, on the other side. Records showed she also had a recent wrist fracture. Continue reading X-rays could provide crucial clues in identifying domestic violence
The New Jersey Department of Health announced that over 3,000 patients at a surgery center may have been exposed to HIV, hepatitis B and hepatitis C.
