Battery could find use in mobile applications, and eventually, electric vehicles with 300-mile range Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory  (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles

Forget meadows. The city’s new park will be filled with edible plants, and everything from pears to herbs will be free for the taking.   Seattle’s vision of an urban food oasis is going forward. A seven-acre plot of land in the city’s Beacon Hill neighborhood will be planted with hundreds of different kinds of

Doing Well While Doing Good For many companies, it’s the holy grail: grow revenue, increase jobs, and be socially responsible at the same time. Sometimes, social responsibility is sacrificed in the name of keeping companies afloat. But these six companies, dubbed Rockstars of the New Economy by B Lab, have achieved three to 100 times

Additionally, this new growing rod system has potentially widespread applications in other disorders   Scoliosis, a progressive condition that causes the spine to grow in a twisted or curved ‘C’ or ‘S’ shape, affects nearly 5 out of every 1,000 children. Although the condition can be present at birth, most cases are diagnosed in children

Millions of tweets analyzed to measure perceived trustworthiness By scanning 66 million tweets linked to nearly 1,400 real-world events, Georgia Institute of Technology researchers have built a language model that identifies words and phrases that lead to strong or weak perceived levels of credibility on Twitter. Their findings suggest that the words of millions of

When it comes to exploring the murky depths of the oceans, autonomous underwater vehicles (AUVs) have become increasingly important over the past decade. These vehicles generally fall into one of two groups: propeller-driven vehicles such as Snookie that can travel fast and carry lots of instruments, but are limited to expeditions of just a few days,

The benefits and risks of “gain-of-function” research into highly pathogenic microbes with pandemic potential must be evaluated, scientists say A group of over 50 researchers has called on the European Commission to hold a scientific briefing on research that involves engineering microbes to make them more deadly. In a December 18 letter to European Commission president

The ancient Japanese art of flower arranging was the inspiration for a groundbreaking technique to create tiny “artificial brains” that could be used to develop personalized cancer treatments. The organoids, clusters of thousands of human brain cells, cannot perform a brain’s basic functions, much less generate thought. But they provide a far more authentic model

A new seismic-resistant, fibre-reinforced concrete developed at the University of British Columbia will see its first real-life application this fall as part of the seismic retrofit of a Vancouver elementary school. The material is engineered at the molecular scale to be strong, malleable, and ductile, similar to steel—capable of dramatically enhancing the earthquake resistance of

Rice U. researchers find nano-thin films of hexagonal boron nitride protect materials from oxidizing Atomically thin sheets of hexagonal boron nitride (h-BN) have the handy benefit of protecting what’s underneath from oxidizing even at very high temperatures, Rice University researchers have discovered. One or several layers of the material sometimes called “white graphene” keep materials
