1,4-Dioxane degradation 12/04/2019

Diverse Types of Microorganisms Work Together to Stably Degrade 1,4-dioxane, a Recalcitrant Pollutant in Industrial Wastewater
– The roles of unknown microorganisms in the natural environment identified by using a new high-sensitivity stable isotope tracing technique –

Using an AIST-developed, high-sensitivity stable isotope tracing technique with a detection sensitivity 500-fold higher than that of the conventional method, AIST discovered many microorganisms that degrade 1,4-dioxane, a persistent artificial pollutant, in petrochemical industrial wastewater. It also showed that these bacteria work together to maintain the stable degradation of 1,4-dioxane.


Genome editing 11/28/2019

Mass Production of Useful Recombinant Proteins Using Chicken Eggs Through Genome Editing
– Expected to realize biological factories with chickens that lay “golden eggs” –

AIST has developed technology to produce genetically modified chickens (knock-in chickens) that lay eggs containing a large amount of human interferon β in the egg white. Knock-in chickens can be bred using male knock-in chickens, so it is possible to reliably produce useful recombinant proteins from one generation to the next.


Cloud computing 12/03/2019

“ABCI” Cloud Computing System for AI Achieves World’s Fastest Deep Learning Speed
– Also ranked fourth in the world for energy-efficient supercomputers –

AIST’s AI Bridging Cloud Infrastructure (ABCI) is a large-scale, energy efficient cloud computing system. A research group of Sony Corporation has updated the record for the world’s fastest deep learning speed. ABCI is ranked fourth in the world for energy efficient supercomputers, and fifth for processing performance using the conjugate gradient method.


Ammonia adsorbent 11/26/2019

An Easily Regeneratable Granular Adsorbent for Clean Air in Livestock Facilities
– Ammonia removal even under actual conditions with humidity and other gases –

AIST has developed a low-cost and reusable ammonia adsorbent using a Prussian blue analogue. A granular adsorbent of diameter 3-5 mm consisting of the adsorbent and a binder was developed. The effectiveness of the adsorption equipment filled with the granular adsorbent was verified by pilot plant in a piggery and a composting facility.


Machine learning 12/02/2019

Computing Method and Circuit to Reduce the Training Process Time of Machine Learning by Up to 80%
– Contributing to expand business opportunities of business operators by speeding up the service optimization process –

AIST has developed a computing method and a circuit to speed up the training process of machine learning. It was demonstrated by simulation that the processing capacity for the training, which is currently difficult to speed up, can be increased by up to five-fold.


Crustal deformation 07/26/2018

Unraveling the Mystery of Crustal Deformation of the Japanese Islands
– Movement of the Philippine Sea Plate causes the east-west contraction –

Thought experiments in combination with analogue models have elucidated the cause of the east-west contraction and crustal deformation of the Japanese islands in the Quaternary Period. It was concluded that the cause of the east-west contraction is not movement of the Pacific Plate itself, as conventionally thought, but rather movement of the Philippine Sea Plate.


Thermoelectric module 08/02/2019

Development of a High-Power Flexible Thermoelectric Module
– Output power of 87 mW/cm2 generated at a temperature difference of 70 °C on a curved heat source –

AIST has developed a high-power flexible thermoelectric module. The developed thermoelectric material is a transition metal-doped bismuth-tellurium alloy. Thermoelectric chips were produced from an ingot of the material and a flexible thermoelectric module was built by mounting the chips at high density on a flexible substrate. The developed module allows to be adhered to heat sources with curved surfaces and can be used for a variety of power generation applications using waste heat.
