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.
Fully charged: Electric vehicles are becoming more popular, but they’re still constrained by how far they’re able to travel on a single charge—a Tesla Model 3 can go for about 350 miles before it needs to be recharged. In a quest to build batteries that can take us farther safely, startup Solid Power is working to make solid-state batteries that could pack more energy into a smaller space.
Battery powered: The company makes battery cells that replace the liquid used as the electrolyte in lithium-ion batteries with ceramic layers. This could unlock new options for battery chemistry, potentially allowing solid batteries to be swapped in. It has taken a step toward testing the technology in vehicles, starting up a large-scale pilot manufacturing line.
A note of caution: Questions remain about whether companies making solid electrolytes will be able to produce them on a large scale. Inorganic materials can be brittle and may be difficult to move during manufacturing. Another concern about solid batteries is how well they can withstand degradation over time. Read the full story.

The big story
Why do you feel lonely? Neuroscience is starting to find answers.
Long before the world had ever heard of covid-19, Kay Tye set out to answer a question that has taken on new resonance in the age of social distancing: When people feel lonely, do they crave social interactions in the same way a hungry person craves food? And could she and her colleagues detect and measure this “hunger” in the neural circuits of the brain?
“Loneliness is a universal thing. If I were to ask people on the street, ‘Do you know what it means to be lonely?’ probably 99 or 100% of people would say yes,” explains Tye, a neuroscientist at the Salk Institute of Biological Sciences. “It seems reasonable to argue that it should be a concept in neuroscience. It’s just that nobody ever found a way to test it and localize it to specific cells. That’s what we are trying to do.”
If Tye succeeds, it could lead to new tools for identifying and monitoring those at risk from illnesses worsened by loneliness. It could also yield better ways to handle what could be a looming public health crisis triggered by covid-19. Read the full story.
