The Download, Mar 9, 2017: Atomic Data Bits, Blockchain Health Records, and Vegetable Tech

The most fascinating and important news in technology and innovation delivered straight to your inbox, every day.

Three Things You Need to Know Today

The World’s Smallest Data Bit
A single atom can now be used to store a binary value. IBM researchers have created the world’s smallest magnet from a single atom of holmium, and it does double duty as the smallest ever data bit, snatching the crown from molecular devices. Using a modified scanning tunneling microscope held within a nanometer of the atom, the researchers are able to both write data, by passing current to flip its magnetic poles, and sense the orientation of its field. The work is basic science, but it could inspire new ways to create small-scale storage.

Is It Time to Invest in Vegetable Tech?
The healthiest foods of all are lacking innovation. Historically, the bulk of agricultural research in the U.S. has been focused on staple crops. But, as Politico points out, just 15 percent of the federal agricultural research budget is spent on specialty crops, which includes virtually all fruit and vegetables. That means efforts to increase yield, shelf life, and convenience for things like leafy greens and squishy berries have been lacking. Given that government guidelines suggest we should pig out on such produce to stay healthy, perhaps it's time to dangle a larger carrot in front of vegetable innovators.

Computer Vision's Video Visions
The AI revolution wants to understand how it's televised. Machine learning is now pretty good at understanding photographs, and has ambitious aims for moving pictures. Yesterday, Google showed off its Video Intelligence tool, which can accurately identify objects and scenes in clips—allowing people to search a video for, say, “cats”— and can even predict what kind of footage it's looking at, such as an ad. Meanwhile, Facebook’s AI chief, Yann LeCun, has loftier goals: he thinks that if AI systems watch enough video, they could even start to learn some common sense.

3-D printers are limited to creating objects as large as the box they’re in. But hang the printer from the roof of a building and you can really go large.

Ever wondered how Silicon Valley startups offer staff so much stock while also convincing outsiders to buy in, too? Sometimes, using a dirty little valuation secret.
