Most of us still pull out a phone, unlock it and tap through an app to do things we do every day, like calling a ride to work or opening a meeting link. On November 5, 2026, a San Francisco hardware startup called Aina unveiled a different idea: an AI ring with a small screen that tries to guess what you need next and puts it at your fingertip before you ask.
Aina was founded in May 2025 by Apoorv Shankar, formerly VP of Hardware at Ultrahuman, and says it spent 15 months in stealth as a hu...

Cyborg Rose: Researchers implant electronic circuits inside plants.
A team of Swedish researchers, by using living roses, has created analogue and digital electronic circuits inside living plants, calling them "electronic plants". The experiment demonstrates wires, digital logic and displays elements fabricated inside the plants that could develop new applications for organic electronics and new tools in plant science. The group at Linkoping University in Sweden, under the leadership of professor Magnus Berggren, used the vascular system of living roses to build...

Disappearing Carbon Circuits on Graphene
Georgia Tech researchers have deposited carbon atoms onto graphene using a focused electron beam process to create patterns that evolve over time on the graphene. The patterns could be used to make reconfigurable electronic circuits, which evolve over a period of hours before ultimately disappearing into a new electronic state of the graphene.
Graphene is also made up of carbon atoms, but in a highly-ordered form. Beyond allowing fabrication of disappearing circuits, the technology could be u...

How the Brain Controls Sleep
MIT neuroscientists have discovered a brain circuit that can trigger small regions of the brain to fall asleep or become less alert, while the rest of the brain remains awake. This circuit originates in a brain structure known as the thalamic reticular nucleus (TRN), which relays signals to the thalamus and then the brain’s cortex, inducing pockets of the slow, oscillating brain waves characteristic of deep sleep. Slow oscillations also occur during coma and general anesthesia, and are associate...

Stick-on Micro-Electric Medical Tattoo Invented
A novel stick on tattoo has been developed that can effectively measure data about the human heart, brain waves and muscle activity.
The latest in medical invention is new type of ultra-thin, self-adhesive electronic device that can effectively measure the aforementioned vital signs without the use of bulky equipment, conductive fluids, or glues.
This product is in the form of a tattoo which has to be applied to the skin like any ink transfer tattoo. It is made from a rubbery polymer subst...
