Mosquitoes’ taste for blood traced to four types of neurons — ScienceDaily

It’s one of the world’s deadliest animals, and it has a taste for human blood: the mosquito.

Mosquitoes spread diseases like malaria, dengue, and yellow fever that kill at least a half a million people each year. Now researchers are learning what humans taste like to mosquitoes, down to the individual neurons that sense blood’s distinctive, delectable flavor.

Female mosquitoes have a sense of taste that is specially tuned to detect a combination of at least four different substances in blood, Howard Hughes Medical Institute Investigator Leslie Vosshall’s team at The Rockefeller University and colleagues report October 12, 2020, in the journal Neuron. The team genetically modified mosquitoes so that researchers could see which neurons fire when a mosquito tastes blood.

“This is definitely a technical tour de force,” says neuroscientist Chris Potter of the Johns Hopkins University School of Medicine, who studies mosquito repellents. Identifying the specific taste

Why Apple Didn’t Need FDA Approval for the Blood Oxygen Tracking Feature in the Apple Watch Series 6

Prior to releasing ECG functionality in the Apple Watch Series 4, Apple needed FDA approval for the feature, but the same isn’t true of Blood Oxygen monitoring in the Apple Watch Series 6 because Apple doesn’t see it as a medical feature.


As outlined by The Verge, pulse oximeters like the blood oxygen tracking feature in the Apple Watch are considered Class II Medical devices and documentation is generally required, but there’s a way around that. If a pulse oximeter is marketed as being for general wellness or fun rather than for a medical purpose, FDA documentation is not required.

That’s the reason why the blood oxygen tracking feature is not being marketed by Apple as a medical feature, and an Apple Support document clearly states that measurements taken using blood oxygen tracking are “not intended for medical use” and are designed for “general fitness and wellness purposes.”

Apple Watch 6’s blood oxygen sensor is unreliable and misleading

An Apple oxygen check a day will not keep the doctor away, at least not yet. The way consumer tech companies are marketing health capabilities is getting ahead of what their gadgets can actually, reliably do. That’s a dangerous trend, and it jeopardizes the potential positive effect that collecting body data could have on our health.

It’s particularly deceptive at a time when many people are looking to health monitors for any clue that they may have covid-19, the illness caused by the novel coronavirus.

For the past week, I’ve been wearing a smartwatch on each wrist, all day and all night long. On the right I have the Apple Watch Series 6, and on the left I wear the new $330 Fitbit Sense, which went on sale this week.

There are many reasons people buy wearable gadgets. I wear an Apple Watch for fitness motivation and to receive phone
