Building batteries better

Looking beyond incremental innovations in energy storage technology, Jie Xiao wants to catalyze a robust domestic battery industry — from mining to manufacturing. Build a better mousetrap, the old saying goes, and the world will beat a path to your door. Build a better battery… and the multitudes should arrive in an endless stream of autonomous electric vehicles. Only, it’s not that simple with energy storage. Most battery innovations begin in academic environments that are designed for discovery rather than the cost, time and scale pressures of industry.

Microfluidics for the masses

In his new book, “How the World Flows,” Albert Folch explores the miniature liquid networks that power natural phenomena, essential innovations and advanced biomedical devices. Rainbows and rubber trees. Aquifers and fountain pens. Gauze pads and glucose strips. Candle wicks and carburetors. Pregnancy tests and 3D printers. Dialysis machines and DNA sequencers. What’s the common denominator? Each is enabled by microfluidics, miniature networks of liquids whose stable properties, at tiny scale, are essential to powering the natural world — and much of the manufactured world, too. And each is explored in Albert Folch’s new book, “How the World Flows,” which invites readers to peer through the microscope into what he calls the “Lilliputian world of fluids at small scales.”

Using computers to design proteins allows researchers to make tunable hydrogels that can form both inside and outside of cells

New research led by the University of Washington demonstrates a new class of hydrogels that can form not just outside cells, but also inside of them. Hydrogels are made up of protein building blocks linked together. Shown here are images of two cells. The cell on the right contains hydrogels decorated with Green Fluorescent Protein (green blobs), whereas the cell on the left does not because it is missing one of the hydrogel building blocks (green is everywhere in the cell).Mout
