Japan just launched a spacecraft to steal soil from the moon of Mars — and bring it back to Earth. That is just the first of eight inventions and discoveries in this Daily Info Dose roundup from October 2026: a hearing implant that upgrades itself, a patch that reads your pulse by changing colour, two kinds of robots going to work, a comet found by accident, a battery made of bricks, and the real reason statins hurt muscles.
1. Japan Is Bringing Back Soil From the Moon of Mars
JAXA's MMX mission lifted off on an H3 rocket on 20 October. It will land on Phobos in 2030, collect at least 10 grams of soil from two sites, and send the sample back to Australia in 2031. A small rover called Idefix will explore the surface first. No country has ever returned a sample from Phobos — and the soil may even contain dust blasted off Mars itself.
2. The First Smart Hearing Implant You Can Upgrade Without Surgery
Cochlear's Nucleus Nexa, named one of TIME's Best Inventions of 2026, carries upgradeable firmware inside the implant. When a better sound program arrives, doctors update it like a phone — no second operation. One surgery, and the implant keeps getting smarter for years.
3. This Octopus Patch Reads Your Pulse by Changing Colour
Scientists at NTNU in Norway built a silicone patch with tiny octopus-style suction cups and a nanostructured surface. Every pulse wave shifts its colour, and a phone camera reads that colour to measure pulse and blood-vessel stiffness. No battery, no wires — and it works on all skin tones.
4. A $20,000 Robot Butler That Finds Your Lost Things
Voxel, from Tuesday Labs in New York City, walks on two legs, tidies rooms, waters plants, and remembers where objects in your home were last seen — including your keys. It costs $20,000, reservations are $200, and US deliveries start in 2028.
5. Humanoid Robots Are Coming to Tractor Factories
Farm giant AGCO has signed with Agility Robotics to pilot the humanoid robot Digit at its Hesston, Kansas plant from 2027 — sorting and stacking parts and placing totes. It is one of the first humanoid robot pilots inside farm-machinery factories at this scale.
6. A Space Telescope Found a Brand-New Comet by Accident
The European Space Agency's Euclid telescope was built to map galaxies and study dark matter and dark energy. Instead, it discovered an active comet — C/2026 S1 (Euclid), about 807.7 million miles away, venting gas and dust. It is the first comet Euclid has ever found.
7. A Giant Battery Made of Bricks
Rondo Energy and Rio Tinto have started detailed engineering on a 360 MWh / 30 MW heat battery at the Yarwun alumina refinery in Gladstone, Australia. It stores midday solar power as heat in refractory bricks and releases steam around the clock. ARENA is funding the study with $3.6 million, with up to $38 million for deployment.
8. Scientists Finally Saw Why Statins Cause Muscle Pain
Teams at UBC and UW–Madison, published in Nature Communications, used cryo-electron microscopy to watch three atorvastatin molecules wedge into one pocket of the RyR1 calcium channel in muscle and hold it open, leaking calcium. That exact picture is the route to safer statins without the muscle ache.
