Human ETs, Tropical Polar Regions, and Self-Eating Cells as a Treatment for Cancer

Earth

Earth scientists have managed to discover a lot of not-earth planets in the last couple of decades, though none of them look to be very much like Earth. Now Eric Ford, a University of Florida astronomer, has published a paper in the Astrophysical Journal that suggests To Curious Aliens, Earth Would Stand Out as Living Planet

If they could measure our planet’s rotation, its atmospheric gases, the presence of abundant water, and calculate what our temperature range must be, our planet would definitely stand out as life-friendly. To intelligent life forms a lot like us, anyway. I don’t know about anyone else, but I find it kind of neat to consider myself as ET. Even though I doubt we’d qualify as cute enough or friendly enough to other ETs for them to want to actually meet us.

Pass the Pectin, Please!

fruit&veggies

A new study from the University of Georgia Cancer Center reports that the fruit and vegetable fiber known as pectin actually kills prostate cancer cells.

“What this paper shows is that if you take human prostate cancer cells and add pectin, you can induce programmed cell death,” said Mohnen, a professor of biochemistry and molecular biology. “If you do the same with non-cancerous cells, cell death doesn’t occur.”

Most home gardeners and canners are familiar with pectin, using commercial concentrations usually derived from citrus peels, apples, crabapples as additives to set jellies, compotes and jams to desired consistency. Pectin is naturally abundant in fruits and vegetables as well as algaes and seaweed.
