The term "fake news" has been popularized by media due to President Donald Trump using it about corporate news outlets in recent years, it was even the plot of the recent Marvel move "Spider-Man: Far From Home" and while its precise meaning has been hotly debated, the spreading of false information to fulfill a political agenda is now a new concept. And it's not just an American thing.

The first potentially habitable world outside of our own solar system is only about 31 light-years away and a new paper models the conditions under which the planet GJ 357 d, discovered a few months ago, could sustain life.

With a thick atmosphere, the planet GJ 357 d could maintain liquid water on its surface like Earth and that means it could be habitable. It is nearby a diminutive M-type dwarf sun, about one-third the size of our own sun,(it is unclear if the planet transits) which harbors three planets, with GJ 357 in that system's habitable zone.

Another paper has disqualified claims by organic industry trade groups, sympathetic academic journalists, and trial lawyer organizations that the weedkiller glyphosate, which acts on plants, somehow causes human cancer

Thee researchers evaluated as yet unpublished data from the Agricultural Health Study (AHS) in the USA, the observation period of which had been extended by eleven years. Through the extended follow-up of the AHS, they come to the conclusion that no connections could be established between applications of plant protection products containing glyphosate and the occurrence of cancer among the examined population group.

A color additive petition submitted by Impossible Foods Inc. requesting the FDA to issue a regulation listing soy leghemoglobin as a color additive for use in such products such as Impossible Burgers has gotten FDA approval.

A new paper states that Einstein still holds up "for now" but that Newton is wrong.

The reason the authors believe Einstein’s general theory of relativity is weak is because it cannot fully explain gravity inside a black hole - and though no one has experimented inside a black hole to get measured data they believe the theory must come first, which happened with Einstein but not with Newton.

Tillage. mixing and churning soil and crop residues like corn stalks, has been around for thousands of years. Even the earliest farmers knew that soil could become depleted and tillage could make the next crop more likely to be successful so we eventually developed a chisel plow for field cultivation, to turn over soil at the end of the growing season.

But not everyone could afford a plow and some just let old stalks break down naturally, a kind of top level composting. Then in the spring they planted new seeds. Some didn't till at all.
