June 15, 2017 laser links: drones for cardiac arrest, aircraft noise and blood pressure, and BMI's effect on fetal malformations
You can get a kit for this Lego drone from kitables, but it won't bring you a defibrillator.
Drones can deliver automatic external defibrillators (AEDs) to cardiac arrests 3 km away in 5 minutes. Drones!
We better hope those drones aren't noisy, though: a couple months ago I stayed in an AirBnB east of downtown San Diego for a few days. We were directly under the final approach for SAN, and except late at night, a plane would roar overhead every few minutes. Bad news for the people in that otherwise charming neighborhood: all that aircraft noise may increase their blood pressure.
In case you woke up in too good of a mood, here's evidence that women with a higher BMI have a higher risk of giving birth to a baby with malformations.
The effect size is small (adjusted risk ratios for any birth defect were 1.05 for BMIs 25–29.9, 1.12 for BMIs 30–34.9, 1.23 for BMIs 35–39.9, and 1.37 for BMIs over 40.
