Reply to comment by chcampb in Researchers develop coating that prevents synthetic fabrics from shedding harmful microplastics in the wash by BlitzOrion

I agree with what you wrote except the wick moisture part especially in the context of hiking and outdoors. Wools do wick moisture but synthetic fabrics do as well. They also dry very quickly, are light, can be worn in warmer temperatures, and often inexpensive. So using them for hiking and exercise is compelling. But there's a time and place for everything and I agree with you that it is better to wear natural fibers as much as possible as long as it makes sense.

Reply to comment by GeoGeoGeoGeo in Earth's inner core seems to be slowing its spin according to new research published in Nature Geoscience. The study authors suggest this might be part of an approximately 70-year cycle where the core speeds up and slows down relative to the rest of the planet. by shiruken

Sure but slowing down the angular momentum of such a large mass would have noticable effects. For example, since the core is spinning at different velocities relative to the outer core then oscillates back to the original velocity then that energy would need to be banked in a magnetic field or some other means so that the energy is regained. We would see strong changes in Earth's magnetic field. Either way, billions of years of this happening would reduce this oscillation to nothing and affect the rate of the spin of the earth as a whole (beyond slowing due to tidal forces).

It might be interesting to think about the moon forming collision and there was an oscillation billions of years ago but much worse than it is today.

It doesn't make sense. First of all, there is considerable friction between the core and mantle so having a spin rate difference between them for billions of years is improbable. Second of all, the theory the core spins faster then slows down also makes no sense. It would imply there is an elastic oscillation between the core and mantle as they trade off angular momentum, but this is something we can measure... If the core slowed, then the mantle would speed up making the day shorter. Since I haven't heard news reports of drastic time changes every 70 years Imma gonna call BS on all this recent news on core spin.

Reply to Newly published research is the first to show that stillbirth can be inherited and tends to be passed down through male members of the family. That risk preferentially comes from the mother’s or father’s male relatives—their brothers, fathers, grandfathers, uncles, or male cousins. by MistWeaver80

How does a risk come from an Uncle or from a cousin when they are not directly related? They may serve as indicators, but the risk doesn't "come" from them. Bad title.
