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.

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.

October Arctic Surprise: Rapid Recovery Of Ice Extent

Written by Dr Benny Peiser

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

Machine Learning To Predict The Trillion Dollar Solar Storm

Written by Robert Hill

There have been 26 significant ‘space weather’ events affecting Earth over the last 50 years. These solar events can severely disrupt the Earth’s magnetosphere (the boundary between the Earth’s magnetic field and the solar wind), and pose a direct threat to electrical infrastructure – knocking out technologies that we rely on every single day, like GPS signals, electrical grids, computers and satellites. To put it lightly, if a major event were to happen tomorrow, it’s likely to cost at least $2 trillion in damages in the first year alone.
