A human hair is somewhere between 60,000 and 120,000 nanometers wide. The new microscope that took this image of a mouse cell can capture 3-D images at a resolution of 30 nanometers.
Other microscopes have achieved higher resolutions, but not without a lot of work. It can take up to two weeks to get this kind of image via electron microscopy, as you take sliver after sliver of the cell and piece the images back together. This system, called X-ray nanotomography, can capture the entire cell in one step.
The smallest of details were visible: the double membrane of the cell nucleus, nuclear pores in the nuclear envelope, membrane channels in the nucleus, numerous invaginations of the inner mitochondrial membrane and inclusions in cell organelles such as lysosomes. Such insights will be crucial for shedding light on inner-cellular processes: such as how viruses or nanoparticles penetrate into cells or into the nucleus, for example.

Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan’s wife, collaborator, and creative director of the Voyager Golden Record, about being […]
The Action Lab took a maglev gyroscope and placed it inside a sealed chamber to see what happens to a levitating gyroscope in a vacuum. A lot of people took issue with the experiment’s setup and explanation, but it’s interesting nonetheless. He responded to those concerns: Hi everyone! I see a lot of comments that […]

Although flagship smartphones are unlikely to adopt heavy-duty outer casing anytime soon, you can always prepare your device for the outdoors with a beefy case and and an external battery like this Nomad Tile Trackable PowerPack, available in the Boing Boing Store for $119.95.The Nomad Tile can fully recharge an iPhone 7 over three times […]
Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
