So apparently, deaf people sneeze silently.
And this article says the sneeze sounds we make are just cultural habits and we don’t even need them. 

Although it does also say “Very little deaf-sneeze research exists”.

Thanks a lot, government.

Sneezing sounds are culturally dependent: they must be another form of warning against pathogens from the nose.

The Trouble with Experts (by lukasig)

This Canadian documentary demonstrates how little many experts know a lot of the time. Karl Popper was not best pleased with the Nobel Committee when they introduced a prize in economics among the sciences.

It then focuses on the perverse incentives that mean we have the pundits with the worst opinions on our television screens.

True useful information is based on the observation of empirical reality, and drawing inferences from that information. Experts sell certainty.

We’re now testing a smart contact lens that’s built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material. We’re testing prototypes that can generate a reading once per second. We’re also investigating the potential for this to serve as an early warning for the wearer, so we’re exploring integrating tiny LED lights that could light up to indicate that glucose levels have crossed above or below certain thresholds.

Almost as exciting as cars that drive themselves, Google is making contact lenses than monitor diabetes.

It is surprising that glucose can be tracked from tears alone, I wouldn’t have thought that the glucose levels within them would be that tightly monitored by normal homeostatic mechanisms.

I wonder if the smart contact lens would simply work by taking single readings, and comparing them against benchmark figures. Probably not, the devices would learn normal for the particular user, and recalculate new values form the public at large. I imagine that it would contain software that could be updated automatically, like an Android phone.

This is probably the first example of a big tech company eating up lots of personal medical data in order to improve public knowledge. I hope Google is kind enough to share it with the public at large, as it will be fascinating, and inform the management of a very common condition.

The History and Future of Everything — Time (by Kurzgesagt)

Seven-minute videos on the Internet are usuallly anathema, but this grandiosely-titled link that I saw on b3ta lives up to its name. It fairly concisely reshaped my thoughts on the timeline of the past, and the future. I can’t believe that Tyrannosaurus rex is chronologically closer to Miley Cyrus than Stegosaurus.

Dreams Are Real #catscatscats by Ryan Barger + Katie Akana)

Thanks, Ali, for drawing my attention to this meticulously choreographed and filmed video of cats playing instruments and licking dinosaurs and so forth. Three minutes wasted, but much better musically than most e.g. Kanye’s new video.
