The average ‘fossil fuel’ (hydrocarbon) power plants that were built or are in process of being built in the last several decades generate an average of 600 – 800 Megawatts each. Although no nuclear plants have been built in the U. S. recently, typical nuclear plants each generate about twice that.

The data-storing abilities of hard drives could soon swell to 40 terabytes (TB) and beyond, says Western Digital. Currently the largest hard disk drive (HDD) that stores data on spinning disks can hold about 14TB of information. Western Digital said the bigger drives were made possible by finding a way to use microwaves to write data on 3.5in drives. The first bigger-capacity drives should go on sale in 2019.
A colony of more than 36,000 Adelie penguins in Antarctica suffered a catastrophic breeding season with just two chicks surviving, experts have said. Extensive sea ice and a drop in temperature caused chicks to freeze to death.

At the ends of the Solar System, beyond the orbit of Neptune, there is a belt of objects composed of ice and rocks, among which four dwarf planets stand out: Pluto, Eris, Makemake and Haumea. The latter is the least well known of the four and was recently the object of an international observation campaign which was able to establish its main physical characteristics.
It is well-known among researchers that the Vikings, those Scandinavian warriors who roamed the seas between the 9th and 11th centuries, made contact with the Islamic world. But new evidence suggests these interactions were greater than previously thought.
Jo Johnson, the UK universities minister, said the government wanted to secure “an ambitious agreement” with the EU to safeguard Britain’s science and innovation, and pledged to allow British universities to continue close research collaboration with their European peers.

Mount Agung in Bali is currently on the verge of eruption, and more than 100,000 people have been evacuated. However, one of us (Dian Fiantis) will go into the area when it erupts, to collect the ash.

In recent years, October has seen some rapid recoveries of Arctic ice extents. But this year may become something special. With the early onset of Siberian snow cover and the resulting surface cooling, ice is roaring back, especially on the Asian side. Consider the refreezing during the last 11 days through yesterday. —Ron Clutz, Science Matters, 7 October 2017
And we wonder what is heating our seas.According to Oregon State University (OSU), there may be more than one million underwater volcanoes. Here’s how their website puts it:
