Researchers said cyclical regeneration of hair follicles is possible
Highlights
Hair follicles were generated in the NFFSE medium
Research was conducted at RIKEN centre in Japan
A team of researchers at the RIKEN Center for Biosystems Dynamics Research in Kobe, Japan, may have just found an answer to hair loss and baldness woes. While many methods have been devised in the past to address hair-related issues, this one is unique, for it's a recipe for continuous cyclical regeneration of hair follicles from hair follicle stem cells. At RIKEN's, a team led by Takashi Tsuji had been working on methods to regenerate lost hair from stem cells. As part of their experiment, the researchers took fur and whisker cells from mice and processed them in controlled conditions with other biological "ingredients" in a laboratory.

One-dimensional Anderson insulators predicted to host bulk photovoltaic effect

Materials in which electrons are strongly localized are promising for use in next-generation solar cells and optoelectronic devices, calculations by a RIKEN theoretical physicist and a collaborator have indicated
1.
Conventional photovoltaic devices such as solar cells and light detectors use a phenomenon known as the photovoltaic effect to convert light into electricity. An essential element of such devices is an interface between a material with an excess of electrons and one with a deficiency of electrons (a p-n junction). But devices based on a single p-n junction have several limitations: for example, their light conversion efficiency is capped at around 34%.

Fujitsu and RIKEN Complete Joint Development of Japan's Fugaku, the World's Fastest Supercomputer

Fujitsu and RIKEN Complete Joint Development of Japan's Fugaku, the World's Fastest Supercomputer
TOKYO, Mar 9, 2021 - (JCN Newswire) - 1. Overview
Fugaku is Japan's supercomputer that has been developed as a core system for the innovative High-Performance Computing Infrastructure (HPCI) promoted by Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT).
In 2014, RIKEN and Fujitsu began joint development of Fugaku and completed delivery of all racks in May 2020. Since then, they have developed and optimized the user environment in preparation for the commencement of shared use.
In the meantime, Fugaku has claimed the world's top spot for two consecutive terms in June and November 2020 in four categories on the major high-performance computer rankings: the TOP500, HPCG, HPL-AI, as well as the Graph 500, and has been used on a trial basis under the "Program for Promoting Research on the Supercomputer Fugaku", "research projects aimed to combat COVID-19", etc. since April 2020. In these trials, two projects, "Study on Large-Scale Numerical Fluid Simulation" and "Largest Ever Meteorological Calculation" have already been selected as the ACM Gordon Bell Prize finalists. In addition, research on "Prediction and Countermeasures for Infection by Virus Contaminated Droplet in Indoor Environment" has led to changes in people's lifestyles, and Fugaku is already making steady progress toward becoming a key technological platform for science and for building Society 5.0.

Anti-hyperlipidemia drug improves brain connectivity in mouse models of schizophrenia

Anti-hyperlipidemia drug improves brain connectivity in mouse models of schizophrenia
New therapies that improve connectivity and circuitry in the brain of people with schizophrenia could result from the discovery by a RIKEN-led team of a potential new target for drugs to treat the psychiatric disorder
1.
Treatment for schizophrenia has not changed much in 60 years. Doctors still generally prescribe medicines designed to tame psychosis by blocking neurotransmitter signaling in the brain. While the drugs ease symptoms such as delusions and hallucinations, they leave many other aspects of the illness untreated and their side effects can be off-putting to many patients. Researchers are thus keen to find new targets for drugs.

Scanning tunneling microscopy reveals origins of stable skyrmion lattices

Scanning tunneling microscopy reveals origins of stable skyrmion lattices
Figure 1: The crystal structure of gadolinium ruthenium silicide, which can host a square lattice of swirling magnetic skyrmions (orange = gadolinium; green = ruthenium; blue = silicon). Modified from Ref. 1 and licensed under CC BY 4.0 © 2021 Y. Yasui et al.
RIKEN physicists have discovered how interactions between electrons can stabilize a repeating arrangement of swirling magnetic patterns known as skyrmions, which could help to further exploit these structures
1.
The spin of an electron causes it to behave like a miniature magnet. In a skyrmion, many of these spins are arranged in a swirling pattern that resembles a tiny tornado. Skyrmions are highly promising as a means of carrying information in a new generation of high-density, low-energy data-storage devices.
