was one of several readers to submit news that drive manufacturer Seagate has announced (and demoed) the first hard drive to squeeze a terabit into each square inch of platter
. "'Initially this will result in 6TB 3.5-inch desktop drives and 2TB 2.5-inch laptop drives, but eventually Seagate is promising up to 60TB and 20TB respectively. To achieve such a huge leap in density, Seagate had to use a technology called heat-assisted magnetic recording (HAMR). Basically, the main issue that governs hard drive density is the size of each magnetic "bit." These can only be made so small until the magnetism of nearby bits affects them. With HAMR, "high density" magnetic compounds that can withstand further miniaturization are used. The only problem is that these materials, such as iron platinum alloy, are more stubborn when it comes to writing data — but if you heat it first, that problem goes away.' With HAMR, Seagate has strapped a laser to the hard drive head; when it wants to write data, the laser turns on. Reading data is still done conventionally, without the laser. In theory, HAMR should allow for areal densities up to 10 terabits per square inch (magnetic sites that are just 1nm long!), and thus desktop hard drives in the 60TB range."Read Replies (0)

First time accepted submitter amcenwest writes with news on the fate of the mis-launched Ekspress-AM4
. From the article: "A modern, state of the art communications satellite stranded last August in a useless orbit will constitute a double failure if Russian officials de-orbit the spacecraft as planned, according to an expert from the team hoping to salvage the spacecraft. 'A new Express AM4 orbit could provide 14 to 16 hours of daily Internet coverage for the international scientific research bases in Antarctica,' said Readdy."
Unfortunately, the satellite is scheduled to begin a deorbiting burn between March 20th and 26th
, so it looks unlikely that it can be salvaged at this point.Read Replies (0)

erice writes about the case of Nicola Wilding: "Injured in crash which damaged the nerves in her arm, she has reached the limits that can what be accomplished with nerve transplants. She can move her arm but doctors have given up hope of restoring use of her hand. So she wants doctors to amputate the hand and replace it with a bionic version that does work."
The doctor, Oskar C. Aszmann
, first performed a similar operation last year

writes "The Chicago Manual of Style (CMS), now in its 16th edition, is the de facto style guide for American writers. It deals with aspects of editorial practice, grammar, usage, document preparation and more. It's just one of many style guides for writers. The Microsoft Manual of Style, just released in its 4th edition, attempts to do for the technical writers what the CMS has done for journalists and other writers."
