Simulations shows magnetic field can change 10 times faster than previously thought

(University of Leeds) A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic field may take place 10 times faster than previously thought.

USA’s Battery500 Initiative Has Achieved Li-Metal Battery Energy Density Of 350 Wh/kg

Toward the end of President Obama’s time in office, the US Department of Energy (DOE) launched a “Battery500 Consortium.” The goal is in the name: reaching 500 Wh/kg battery energy density with lithium-metal battery cells, a target which was reportedly triple the battery energy density at the time

New insights into how genes control courtship and aggression

Fruit flies, like many animals, engage in a variety of courtship and fighting behaviors. Now, scientists have uncovered the molecular mechanisms by which two sex-determining genes affect fruit fly behavior. The male flies’ courtship and aggression behaviors, they showed, are mediated by two distinct genetic programs. The findings demonstrate the complexity of the link between sex and behavior.

Researchers are making recombinant-protein drugs cheaper

The mammalian cell lines that are engineered to produce high-value recombinant-protein drugs also produce unwanted proteins that push up the overall cost to manufacture these drugs. These same proteins can also lower drug quality. Researchers have now shown that their genome-editing techniques could eliminate up to 70 percent of the contaminating protein by mass in recombinant-protein drugs produced by the workhorses of mammalian cells — Chinese Hamster Ovary (CHO) cells.
