Scientists design super-battery made with cheap, readily affordable chemical element, Na — Salt-based cell has surprisingly good energy density and charges in seconds

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-performance, hybrid sodium-ion battery that charges rapidly and offers impressive energy density.  This revolutionary prototype uses sodium (Na), a chemical element over 1000 times more abundant and cheaper than lithium (Li), the main component of conventional batteries. Generally, sodium-ion batteries face … Read more

Scientists discover first algae that can fix nitrogen — thanks to a tiny cell structure

A Braarudosphaera bigelowii cell magnified 1,000-fold.Credit: Tyler Coale Researchers have discovered a type of organelle, a fundamental cellular structure, that can turn nitrogen gas into a form that is useful for cell growth. The discovery of the structure, called a nitroplast, in algae could bolster efforts to genetically engineer plants to convert, or ‘fix’, their … Read more
