Stuff is constantly falling down on the Earth from outside its atmosphere. This might be very large rocks that we will notice to specks of dust that fall and float down. Currently, estimates of the Earth’s intake of space dust vary from around five tons to as much as 300 tons every day. The Cosmic…

The Younger Dryas, also referred to as the Big Freeze, was a geologically brief (about 1,300 years) period of cold climatic conditions and drought which occurred about 12,000 years ago. The Younger Dryas stadial is thought to have been caused by the collapse of the North American ice sheets, although rival theories have been proposed.…

Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems. Obviously there are costs associated with obesity usually long term health costs. A recent Canadian study confirms that physical inactivity is a…

As global warming proceeds the frozen arctic tundra will turn into forest or grass lands. In just a few decades shrubs in the Arctic tundra have turned into trees as a result of the warming Arctic climate, creating patches of forest which, if replicated across the tundra, might accelerate global warming. Scientists from Finland and…

When do mountain landslides occur? Mountain ranges are formed with sharp and steep ridges due to tectonics. When do they become unstable? Some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful streams cutting into hillsides, leading to erosion in…

The Permian–Triassic extinction event, sometimes known as the Great Dying, was an extinction event that occurred 250 million years ago, forming the boundary between the Permian and Triassic geologic periods, as well as the Paleozoic and Mesozoic eras. It was the Earth’s most severe known extinction event, with up to 96% of all marine species…

Volcanoes tend to be unpredictable. It would be nice to know when and why an eruption may occur. A forensic approach that links changes deep below a volcano to signals at the surface is described by scientists from the University of Bristol in a paper published today in Science. The research could ultimately help to…

Curry is a generic term primarily employed in Western culture to denote a wide variety of dishes originating in Indian, Pakistani, Bangladeshi, Sri Lankan, Thai or other Southeast Asian cuisines. Their common feature is the incorporation of more or less complex combinations of spices / herbs, usually (but not invariably) including fresh or dried hot…

The bottom of the sea is dark and lonely. Yet there is life usually isolated and located near some source of energy such as a deep sea vent. these vents are not continuous and in between there is a lot of empty space and totally alien environmental conditions especially between the bottom of the sea…

There are several ways to remove CO2 from a stack gas. None have reached a commercial basis yet due to the expense of the processing. The current method of removing the greenhouse gas carbon dioxide (CO2) from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So…
