Smallest and tightest knot ever tied is made of just 54 atoms

Posted on by

The new knot takes the basic structure of a trefoil knot (pictured)

Whether it was in your shoelaces or earbud cables, we’ve all accidentally tied knots that we can’t untangle – but we don’t expect to win any world records with them. Now scientists have done exactly that, accidentally tying the world’s smallest and tightest knot in a tiny structure made of just 54 atoms.

An electron microscope image of the world's smallest moustache, modeled by a red blood cell

Australian scientists have created the world’s smallest moustache, tiny enough to be modeled by a single red blood cell. Measuring just 5 microns wide, the micro-mo was designed to raise awareness for men’s health.

Hangar Connect claims title of “world’s smallest bike stand”

Posted on by

The Hangar Connect sells for US$225

While bicycle repair stands certainly come in handy, they can be rather awkward to bring on road trips, or to set up in small apartments. The Hangar Connect offers a more compact alternative, as it simply gets clamped onto whatever’s at hand.

“World’s smallest record” engraved with part of a Christmas song

Posted on by

The record is just 14 microns wide, and contains the first 25 seconds of the song

Last year, scientists at the Technical University of Denmark (DTU) got in a festive mood and created “the world’s thinnest Christmas tree.” This time, they’ve produced what they claim is the world’s smallest record, complete with a Christmas tune engraved into it.

World’s smallest battery assembles itself like a Swiss roll cake

Posted on by

Professor Oliver G. Schmidt holds up a flexible chip that can be equipped with a number of tiny cake-inspired batteries, alongside team member Dr. Minshen Zhu

The ongoing miniaturizing of electronics calls for an ongoing reimagining of the devices that power them, and a new example from scientists at the Chemnitz University of Technology has taken this technology into tiny new territory. By deploying what’s described as a Swiss-roll-inspired self-assembly process, the researchers have produced the world’s smallest battery, which they say could find use in powering small sensors in the human body, among other applications.

Dust-sized supercapacitor packs the same voltage as a AAA battery

An array of 90 tubular biosupercapacitors

By combining miniaturized electronics with some origami-inspired fabrication, scientists in Germany have developed what they say is the smallest microsupercapacitor in existence. Smaller than a speck of a dust but with a similar voltage to a AAA battery, the groundbreaking energy storage device is not only safe for use in the human body, but actually makes use of key ingredients in the blood to supercharge its performance.

The newly discovered Nano-Chameleon (Brookesia nana) is the smallest known reptile in the world

A tiny new species of chameleon has been discovered, and it seems to be the smallest reptile in the world. Known as Brookesia nana, or the nano-chameleon, the petite species can perch on a fingertip and may have the smallest adult males of any vertebrate.

WINNER 'First Light'. Bogra, Bangladesh

Global photography social network Agora’s latest contest tasked its community with taking portraits of small things, and the resulting highlights run the gamut from an extraordinary close up of a tiny damselfly to some shots of humans eclipsed by the scale and majesty of Mother Nature.
