Scientists Identify Factors That Make People Naturally Resistant to H.I.V.

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 3D print complex vascular networks

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.

Doctors Identify Very Rare ‘Semi-Identical’ Twins

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.

MIT built a health-tracking sensor that can ‘see’ through walls

An MIT professor has built a prototype device that can wirelessly track your health — even through walls — using a mix of radio signals and machine learning. Dina Katabi’s gadget resembles a WiFi router and is designed to sit in your pad and monitor your breathing, heart rate, sleep, gait, and more as you go about your day. It’s already doing that in over 200 homes around the US of both healthy people and those with Parkinson’s, Alzheimer’s, depression, and pulmonary diseases.
