What does this mean?
Neo,
Incase you are asking about ES, I was abbreviating Eight Sleep = ES
But, I think you are asking about the zipping part…
The mattress cover they sell is a case that zips around your existing mattress. The top portion contains the water tubes. The rest of it serves no purpose other than to keep it formed tightly to your mattress.
Once you zip it up, if you have a soft mattress, it’s tight enough that it changes how soft your existing mattress feels… it will become firm. So, I simply leave it unzipped and then it’s as if it’s just resting on my mattress. I’ve done this since day one and it’s never been a problem.
My new Orion ships this month, so I’ll be back to give it a review. I expect it to be every bit as good, but??
Ok, thx (yes, the zipping part)

It’s available and used widely – Non-invasive Hb trackers can also indicate hydration levels (there are many).

This is not newsworthy but just a plug for the Apple Watch.
I was sitting next to a friend at dinner who was just gifted an Apple Watch. He said I need to get one, and my reply was I’m not sure I want to spend the money yet because I already have an oura ring and I keep waiting for the next gen Apple Watch that will have more health safety features….
He shared that he put on his new watch and was immediately told he has AFIB! Zero symptoms. He called his doc and was asked to send the info from the watch. The doc said I could have you go to the hospital but the readings from the watch are good enough I don’t feel you need to…
My husband has a watch, so I’m thinking I’ll at least put his on once every week or two incase it tells me anything.

It costs like $212 used on Backmarket (Watch 9 for hypertension notifications as well) and you’ll have features like fall, crash detection, automatic calling emergency services and emergency contacts if fall detected and unconscious, afib, best sleep tracking if you use it for that, temperature, now they have sleep score. You need an iPhone. It’s a cheap solution to improve health for elderly so get it for your parents or grandparents. Tell them to wear it during the night and charge it everyday in the day.

Researchers create world’s smallest programmable, autonomous robots
https://techxplore.com/news/2025-12-world-smallest-programmable-autonomous-robots.html
Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices.
Powered by light, the robots carry microscopic computers and can be programmed to move in complex patterns, sense local temperatures and adjust their paths accordingly.
Described in Science Robotics and Proceedings of the National Academy of Sciences, the robots operate without tethers, magnetic fields or joystick-like control from the outside, making them the first truly autonomous, programmable robots at this scale.

This Is the Blood Glucose Monitor We’ve Been Waiting For
Makers of smartwatches and other wearables have spent years trying to measure blood sugar without pricking your skin. The PreEvnt Isaac does just that, and you wear it like a necklace.
All this is to explain why I could scarcely believe that the PreEvnt Isaac was real when I saw it here at CES 2026 in Las Vegas. The Isaac is a small device, about the size of a quarter. Instead of tracking blood glucose optically through the skin, it measures volatile organic compounds in your breath to detect biomarkers like acetone that can be correlated with rising blood glucose levels.
You might not be able to wear it in a smart ring or watch, but a small device that you can wear around your neck or keep in your bag without having to retreat to the bathroom to prick your skin is a huge step up in quality of life for many, many people.

This looks quite cool too and resonable priced:

They can also do eg free T
That seems also quite reasonably priced

Best health tech
Withings Body Smart 2
Image: Withings
This year’s show was all about longevity tech, and some pretty cursed ways to tackle that concept. Mostly involving several bodily fluids and inconvenient tests. The Withings Body Scan 2, however, is a scale, and everyone knows how to use a scale.
The interesting thing: Withings is positioning this device less as a scale and more as a “longevity station.” It measures over 60 biomarkers, concentrating on cardiovascular and non-invasive metabolic health. It does the latter by measuring minuscule amounts of foot sweat. (And while technically foot sweat is a bodily fluid, I’ll take that over urine or blood.)
More so than the fancy metrics, what I like here is the concept of decentering weight from the entire purpose of a scale. It’s encouraging users to view their weight as one part of their health — not the entire measure. My only gripe is that the scale will cost a whopping $600, but hopefully the price for this kind of tech comes down over time. — Victoria Song, senior reviewer

L’Oréal LED Face Mask

This was a ho-hum year for wearables at the show, so I was pleasantly surprised by L’Oréal’s take on an LED face mask — a product category I generally hate. It’s conceptually based on a sheet mask, meaning it’s much easier to wear than the typical, Jason Voorhees-esque LED masks you’ll find on the show floor. It’s made of a flexible, silicone-esque material, and the light sits much closer to your skin. There’s also a smaller version that fits just under the eyes. The flexible material also means that, down the line, you could see this technology applied to other body parts, such as the neck or decolletage. Plus, you only have to wear it for five to 10 minutes.
What I appreciate about this mask is that L’Oréal has disclosed it uses 630nm and 830nm wavelengths, and that it’s going through the extra hoops of 510(k) FDA clearance. No one needs red light therapy masks, and it’s totally fine if you don’t believe it’s a useful therapy. However, the combination of a smarter design, transparent labeling, and regulatory compliance is the type of innovation I want to see in a market that’s rampant with scammy versions of the same gadget. — Victoria Song, senior reviewer
This could be a great product if it is accurate, but I found no data on the website about accuracy.
Risks:
Under pressure to generate revenue and unconstrained by guardrails, a number of leading AI companies will adopt business models in 2026 that threaten social and political stability—following social media’s destructive playbook, only faster and at greater scale.
We remain bullish on AI’s revolutionary potential. Today’s frontier models reason through complex problems, show their work, and are embedded in coding, research, and knowledge workflows. The hyperscalers are offloading large chunks of software development to AI, accelerating their own R&D cycles. In biotech and materials science, AI is opening new research pathways—though commercial breakthroughs remain mostly ahead of us. Hundreds of millions of people now use chatbots daily for everything from drafting emails to debugging code and learning new skills. This is real, and it’s just the beginning.
