Elucidation of bone regeneration mechanism

Fish have the extraordinary ability to regenerate lost fins and other appendages containing cartilage and bone. The cells responsible for the regeneration offer new clues on how to regenerate tissues in humans. Researchers at Tokyo Institute of Technology (Tokyo Tech) have found a dormant progenitor cell population in zebrafish that regenerates bone cells, or osteoblasts. The study can be read in Developmental Cell.

Antiaromatic molecule displays record electrical conductance

Researchers demonstrate high electrical conductance for an antiaromatic nickel complex — an order of magnitude higher than for a similar aromatic complex. Since the conductance is also tunable by electrochemical gating, antiaromatic complexes are promising materials for future electronic devices. Organic materials often have a lower production cost than traditional electric conductors like metals and semiconductors. Not all organic sys...

Scanning the surface of lithium titanate

Researchers at Tokyo Institute of Technology, Tohoku University, and the University of Tokyo have applied advanced scanning methods to visualise the previously unexplored surface of a superconductor, lithium titanate (LiTi2O4). LiTi2O4 is the only known example of a so-called spinel1 oxide superconductor. Its rarity makes LiTi2O4 of enormous interest to those studying the origins of superconductivity, as it has the highest superconducting tr...

Cancer control strategy from African clawed frog unveiled

A scientist at Tokyo Institute of Technology has discovered evolutionary fragility of genes encoding cyclin-dependent kinase inhibitors (CDKIs) in African clawed frog (Xenopus), suggesting novel mechanisms suppressing proliferation of cancer cells instead of CDKIs in these species. In their growth and development, all living organisms go through the cell cycle which is controlled by a triad of cyclin-dependent kinases (CDKs), cyclins, and CD...

AI dramatically increases image clarity under severe conditions

The research group of Professor Masatoshi Okutomi and Visiting Associate Professor Masayuki Tanaka of Tokyo Institute of Technology and NEC announced their joint development of a multi-modal image fusion technology that dramatically improves the clarity of images by using artificial intelligence (AI) to automatically combine visible images taken by standard cameras with non-visible images taken by specialised devices, such as thermal or terahertz...

Transparent ceramics make super-hard windows

Scientists have synthesised the first transparent sample of a popular industrial ceramic at DESY. The result is a super-hard window made of cubic silicon nitride that can potentially be used under extreme conditions like engines, as the Japanese-German team writes in the journal Scientific Reports. Cubic silicon nitride (c-Si3N4) forms under high pressure and is the second hardest transparent nanoceramic after diamond but can withstand substantia...
