Uh, Earth’s Inner Core Just Stopped Spinning
Ok, just let me off this decade already.
Our understanding of Earth’s inner core doesn’t have a strong history. Ancient days, of course, had folks believing in a hollow core. Then came the understanding of iron and a molten mixture making up Earth’s middle, coupled with the theory of spinning happening separate from the rest of Earth. Song confirmed the spinning theory in 1996.
A strong Stratospheric Warming event is about to start, impacting the Polar Vortex as we head into the final month of the Winter Season
The Polar Vortex is starting to weaken as a strong Stratospheric Warming event is about to unfold. As the forecast indicates, the Polar Vortex will be heavily deformed but will not fully collapse. These important events can have a significant impact on the rest of Winter in the United States, Canada, and Europe.
Weather and the stratospheric Polar Vortex are strongly connected, especially in Winter. So it matters greatly in what shape or form the Polar Vortex is as we go through the cold weather season.
We will look at the important role of the Polar Vortex during the Winter season and how it can shape our weather when it is strong or weak. But more importantly, we will look closely at the latest forecasts and how the Polar Vortex disruption events might be a major player for the rest of Winter.
Another company is opening a regional HQ in North Texas
The San Jose, Calif.-based company on Thursday announced plans for the new regional headquarters in Frisco.
McAfee will open offices at The Star development, where the Dallas Cowboys are headquartered, by the middle part of this year, according to a release from Frisco city officials.
“Our decision to choose Frisco for our regional HQ was also based on the diverse cultural destination the city has become, and the many opportunities our team members will have to be immersed in the community and to give back to the many non-profit organizations here,” Benni Bueckert, a McAfee vice president, said in the release.
Female and male hearts respond differently to stress hormone in mouse study
A new study published in Science Advances shows female and male hearts respond differently to the stress hormone noradrenaline. The study in mice may have implications for human heart disorders like arrhythmias and heart failure and how different sexes respond to medications.
The team built a new type of fluorescence imaging system that allows them to use light to see how a mouse heart responds to hormones and neurotransmitters in real time. The mice were exposed to noradrenaline, also known as norepinephrine. Noradrenaline is both a neurotransmitter and hormone associated with the body’s “fight or flight” response.
The results reveal that male and female mouse hearts respond uniformly at first after exposure to noradrenaline. However, some areas of the female heart return to normal more quickly than the male heart, which produces differences in the heart’s electrical activity.
