A theoretical explanation for an enhanced thermal Hall response in high-temperature superconductors
A few months ago, a team of researchers led by Louis Taillefer at the University of Sherbrooke measured the thermal Hall conductivity in several compounds of copper, oxygen and other elements that are also high-temperature superconductors known as 'cuprates.' In physics, the thermal Hall effect describes heat flow in a direction transverse to a temperature gradient.

Nature Communications, Published online: 31 October 2019; doi:10.1038/s41467-019-12961-5 Microbial production of aromatic amino acid (AAA)-derived chemicals remains an outstanding metabolic engineering challenge. Here, the authors engineer baker's yeast for high levels p-coumaric acid production by rewiring the central carbon metabolism and channeling more flux to the AAA biosynthetic pathway.

Research reveals how malaria parasite plans ahead, preparing blueprint to strike in humans
Within seconds after an infected mosquito bites, the malaria parasite navigates the host skin and blood vessels to invade the liver, where it will stay embedded until thousands of infected cells launch malaria's deadly blood-stage infection.
