When called on to explain why he lives in a gigantic mansion with its resulting environmental cost, Academy Award winner, Nobel laureate, and U.S. Vice-President Al Gore said he bought carbon offsets from a company he owned that sold carbon offsets.

Paying himself to emit greenhouse gases sounded ridiculous but a new analysis shows that buying offsets - paying a company to plant trees - can be just plain risky. 

Forests absorb carbon dioxide from the atmosphere, but if they are managed by a group that doesn't believe in logging or clearing brush. If a forest goes bust in a fire all that stored carbon goes up in smoke again.

There have been more celebrity suicides during the COVID-19 pandemic and while tragic, they may help to bring great awareness to the risks of depression and anxiety in other populations at all times. Such as pregnant and postpartum women.

How did the continents form? It's a complex question, and no firm answers will be coming soon, but the oceanic plateau of the Kerguelen Islands may provide part of the answer, according to a new paper.

From a geological point of view, it is the Earth's outermost layer that distinguishes the continents from the oceans: oceanic crust, which is relatively thin, is mainly made up of basalts, resulting from the melting of the Earth's underlying mantle, whereas continental crust, which is thicker and of granitic composition, is derived from magmas that evolved at depth before solidifying.

Netflix is the big name in streaming, virtually everyone who has any interest in digital shows has heard of them, but they still give you a free trial.

No matter your size, and even if it's an existing customer, it makes good business sense, finds a new paper.

How big is the universe? No one really knows, but since we are in just one Orion spur of the arm of Sagittarius in one galaxy, and there are an unknown number of galaxies, it's big. So big our galaxy alone could have 6,000,000,000 planets like ours, according to a new estimate.

To be a potential planet like Earth, the new model estimating the number of planets like ours must be rocky, roughly Earth-sized and orbiting Sol-like (G-type) stars. It also has to orbit in the habitable zones of its star, which is the range of distances from a star in which a rocky planet could host liquid water  on its surface.

A few decades ago, Asian diets were regarded as superior because lower incomes meant they ate less meat - and those who were tested had less cholesterol, a substance found in the blood that the body uses to build healthy cells, but which can lead to a build-up in blood vessels. Cholesterol has been correlated to a risk factor for a risk factor for heart attacks.
