Roundtables: Why 2026 Is the Year for Sodium-Ion Batteries

Listen to the session or watch below Sodium-based batteries could be a cheaper, safer alternative to lithium-ion, and the technology is finally making its way into cars—and energy storage arrays on the grid. Sodium-ion batteries are one of MIT Technology Review’s 10 Breakthrough Technologies of 2026 list, and this subscriber-only discussion explains why. Watch a…

The Download: introducing the Crime issue

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Introducing: the Crime issue Technology has long made crime and its prosecution a game of cat and mouse. But those same new technologies that have allowed crime to outpace law have also reenergized…

Now is a good time for doing crime

Eons ago, in 2012, I had a weird experience. My iPhone suddenly shut down. When I restarted it, I found it was totally reset—clean, like a new device. This was the early days of iOS, so I wasn’t too concerned until I went to connect it to my computer to restore it from a backup.…

Listen to Earth’s rumbling, secret soundtrack

The boom of a calving glacier. The crackling rumble of a wildfire. The roar of a surging storm front. They’re the noises of the living Earth, music of this one particular sphere and clues to the true nature of these dramatic events. But as loud as all these things are, they emit even more acoustic…

Reformulated antibodies could be injected for easier treatment

Antibody treatments for cancer and other diseases are typically delivered intravenously, requiring patients to go to a hospital and potentially spend hours receiving infusions. Now Professor Patrick Doyle and his colleagues have taken a major step toward reformulating antibodies so that they can be injected with a standard syringe, making treatment easier and more accessible. …

A I-designed proteins may help spot cancer

Researchers at MIT and Microsoft have used artificial intelligence to create molecular sensors that could detect early signs of cancer via a urine test. The researchers developed an AI model to design short proteins that are targeted by enzymes called proteases, which are overactive in cancer cells. Nanoparticles coated with these proteins, called peptides, can…

A new way to rejuvenate the immune system

As people age, their immune function weakens. Owing to shrinkage of the thymus, where T cells normally mature and diversify, populations of these immune cells become smaller and can’t react to pathogens as quickly. But researchers at MIT and the Broad Institute have now found a way to overcome that decline by temporarily programming cells…

A retinal reboot for amblyopia

In the vision disorder amblyopia (or “lazy eye”), impaired vision in one eye early in life causes neural connections in the brain’s visual system to shift toward supporting the other eye, leaving the amblyopic eye less capable even if the original impairment is corrected. Current interventions don’t work after infancy and early childhood, when the…

Just pull a string to turn these tile patterns into useful 3D structures

MIT researchers have developed a new method for designing 3D structures that can spring up from a flat sheet of interconnected tiles with a single pull of a string. The technique could be used to make foldable bike helmets and medical devices, emergency shelters and field hospitals for disaster zones, and much more. Mina Konaković…
