In the course of our research for clients, we come across emerging technologies, new materials, new chemistries, growing markets, changing regulatory landscapes, innovative business models, and much more. Every other Friday, we pick five articles, videos, or podcasts that we found interesting and send them your way.

Superconductor Boosts Lithium-Sulfur Battery Performance

Next-generation batteries based on lithium-sulfur chemistry could store more energy in lighter packages than today’s best lithium-ion batteries. But the intricacies of Li-S chemistry also limit its durability. Now researchers have found they can rein in the chemistry of Li-S cathodes by adding nanoparticles of the superconductor magnesium diboride. [C&EN]

Carbon Dioxide Emissions from the U.S. Power Sector Have Declined 28% Since 2005

Carbon dioxide emissions from the electric power sector have been on a steady decline and are now at the lowest level since 1987. Driven by low demand, state policies, and federal tax incentives encouraging the use of noncarbon electric generation like solar and wind, this decline in emissions will likely be a continuing trend.

Lean StartUp’s Newest Tool: Innovation Accounting

A recent study of 1200 executives found that over half of them struggle with connecting their business and innovation strategies. Almost 75% believe they are not out-innovating their competition. Eric Ries, author of The Startup Way, thinks it’s because companies are measuring their progress using wild guesses; they should start using science instead. [INC]

PHYSICS

Redefining the Kilogram

The official object that defines the mass of a kilogram is a tiny, 139-year-old cylinder of platinum and iridium that resides in a triple-locked vault near Paris. Because it is so important, scientists almost never take it out; instead they use copies called working standards. But the last time they did inspect the real kilogram, they found it slightly heavier than all the working standards, which have been leaving behind a few atoms of metal every time they are put on scales. The result: representatives from 57 countries are meeting this month to vote on a proposal to make the International System of Units fully dependent on constants of nature. The ampere, kelvin, mole, and kilogram are all expected to get new definitions. [SCIENTIFIC AMERICAN]

The 8 Best Science Images, Videos, and Visualizations of the Year

From basic principles that explain our universe, to the newest technology, science can be weird, fun, and down right exciting. But science can also be strikingly beautiful. These 8 visuals are the best this year that not only explain scientific concepts clearly, but also show just how stunning science can be. [POP SCI]
