A research team from Utrecht University has successfully fabricated working livers using a newly developed ultrafast volumetric 3D bioprinting method.

By means of visible light tomography, the volumetric bioprinting method enabled the successful printing of miniature stem cell units by making the cells “transparent”, which meant they retained their resolution and ability to perform biological processes.

Printed in less than 20 seconds, the liver units were able to perform key toxin elimination processes mimicking those that natural livers perform in our bodies, and could open new opportunities for regenerative medicine and personalized drug testing.

The new microbattery is roughly the size of a gain of dust – less than one square millimeter – and has a minimum energy density of 100 microwatt hours per square centimeter. To achieve this, the team winded up current collectors and electrode strips made of polymeric, metallic, and dielectric materials at the microscale. The researchers used Swiss-roll or micro-origami process.

The layered system with inherent tension is created by consecutively coating thin layers of polymeric, metallic, and dielectric materials onto a wafer surface. The mechanical tension is released by peeling off the thin layers, which then automatically snap back to roll up into a Swiss-Roll architecture to create a self-wound cylinder microbattery. The method is compatible with established chip manufacturing technologies and capable of producing high throughput microbatteries on a wafer surface.

The team behind the world’s smallest battery says it could be used in the human body, where tiny sensors and actuators require a continuous power supply. They also claim that the rechargeable microbatteries could also power the world’s smallest computer chips for about ten hours – for example, to measure the local ambient temperature continuously. In addition, it has great potential in future micro-and nanoelectronic sensorics and actuator technologies, in the Internet of Things, miniaturized medical implants, microrobotic systems, and ultra–flexible electronics.

The science of human hibernation and ‘torpor’ may soon catch up with science fiction, not only facilitating space travel but potentially helping treat cancer.

This looks interesting.

If it can detect underground structures, not only might it detect tunnels, but it might make tunneling easier.


An object hidden below ground has been located using quantum technology—a long-awaited milestone with profound implications for industry, human knowledge and national security.

University of Birmingham researchers from the UK National Quantum Technology Hub in Sensors and Timing have reported their achievement in Nature. It is the first in the world for a quantum gravity gradiometer outside of laboratory conditions.

🚨 A major breakthrough.


Scientists have successfully implanted an artificial neuron into a Venus Flytrap, in what could be a major breakthrough in the merging of living things and computers.

The neuron was able to control the plant, making its lobes close, the scientists report.

That in turn could be a major step towards the development of brain-machine interfaces as well as intelligent robots, they suggest. Such technology will require computers and living things to combine – but that has so far proven difficult.
