DNA is the blueprint for life, and now it can serve as a computer to monitor life’s processes. Bioengineers transformed DNA into a one-bit memory system that can record, store and erase data within living cells. A future DNA memory device could be used to track cell division and differentiation in cancer patients, perhaps, or to monitor what happens as cells get sick or age.
An international team of researchers claims to have figured out a way to use ultrafast bursts of heat, rather than the typical magnetic field, to record a bit of information on a hard drive--a development they say could vastly increase the efficiency and speed of hard drives. They say it could record multiple terabytes per second, hundreds of times faster than current methods.
The world’s smallest magnetic data storage unit is made of just 12 atoms, squeezing an entire byte into just 96 atoms, a significant shrinkage in the world of information storage. It’s not a quantum computer, but it’s a computer storage unit at the quantum scale. By contrast, modern hard disk drives use about a million atoms to store a single bit, and a half billion atoms per byte.
It’s good smoked, straight up on the grill with a little lemon and butter, or rolled into sushi. And now, thanks to researchers at Taiwan’s Tsing Hua University and the Karlsruhe Institute of Technology in Germany, salmon is also good sandwiched between two electrodes. Using silver nanoparticles, a couple of electrodes, and a thin layer of salmon DNA, those researchers have developed a “write-once-read-many-times” (WORM) data-storage device that they think could eventually lead to a replacement for silicon.
Despite this era's amazing advances in data storage and data mining, the accumulated records of our federal bureaucracy are largely — and perhaps unsurprisingly — languishing in the early 20th century. Paperwork and filing cabinets still comprise the bulk of government records.
The most controversial scientific topic of the past few decades--predicting the fate of the planet--gets a huge dose of data

Before the International Panel on Climate Change launched its Data Distribution Centre (DDC) in 1998, researchers who needed climate-change projections had to get them from the handful of scientists who specialized in computing-intensive statistical climate modeling. Modelers became backlogged with requests; studies languished.
The EOL, a collaboration by the foremost authorities in biology, is a massive database that tracks every organism on Earth

Four years ago, the Smithsonian Institution, the Field Museum of Natural History, Harvard University, the Missouri Botanical Garden, the Marine Biological Laboratory and the Biodiversity Heritage Library joined together to create a comprehensive collection of data about every living thing on Earth.
A massive directory of all viruses, worms, and other malware--as well as a centralized anti-malware arsenal

With a catalog of more than 15 million malicious computer programs, MD:Pro is the Centers for Disease Control of the cybersecurity world. Frame4 Security Services, which was established in the Netherlands in 2006, created the database as a resource for security experts, who need access to malware to identify new threats and develop and test defenses.
The National Geographic Society and IBM sell DNA-testing kits to trace human history scientifically

The best record of early human migration is found not in ancient bones or archaeological artifacts, but in the DNA of people living today. In 2005, to make that information accessible, the National Geographic Society and IBM launched the Genographic Project.
