Osaka Prefecture University develops a method to design and control the path of electron flow in a polycrystalline material. Using epitaxial growth approach, researchers address the electrical conductivity problem of thin film materials by realizing a highly conductive in-plane orientation of a metal-organic framework. Furthermore, they show that it is possible to fabricate oriented thin film patterns by integration with UV lithography technology.

Japanese and Zambian scientists have shown that environmental lead poisoning in children affects not only their own health and wellbeing, but the vitality and mental health of their mothers, as well.

Magnetic layers interact with sunlight differently, creating a temperature gradient that generates electricity day and night.

Researchers have identified a new treatment candidate that appears to not only halt neurodegenerative symptoms in mouse models of dementia and Alzheimer’s disease, but also reverse the effects of the disorders. The treatment candidate has been declared safe by Japan’s governing board, and the researchers plan to begin clinical trials in humans in the next year.

A new non-invasive technique scans “chemical fingerprints” to see if ordinary cells’ reprogramming into stem cells is on track and verify transformation success by matching “print” patterns.

Many waterbird species which travel across hemispheres are affected by a wide range of environmental and anthropogenic factors. A first-of-its-kind study along the China coast, jointly conducted by the Science Unit of Lingnan University in Hong Kong (LU) and the Hong Kong Bird Watching Society (HKBWS), quantified the 20-year wintering population trends of 42 waterbirds species in the Deep Bay area to evaluate the impacts of different threats along the East Asian-Australasian flyway (EAAF), providing important baseline information and recommendations on conservation.

Perovskite colloidal quantum dots (Pe-CQDs) are highly promising nanocrystals for optoelectronic applications. However, the size of the crystals should ideally be equal to ensure a consistent energy landscape. In a recent study, scientists clarified the relationship between differences in particle size—polydispersity—and the optoelectronic characteristics of Pe-CQDs. They showed that using equally sized, or ‘monodisperse,’ quantum dots results in markedly better performance in Pe-CQD solar cells, paving the way for future optoelectronic devices.

A ring-expanded porphyrin with no meso-bridges comprised of an odd number of pyrroles was successfully synthesized via the oxidative coupling of the corresponding terpyrrole. This porphyrin showed a 34pi aromatic character and an intense absorption at the near-infrared region. We analyzed the optical and electronic structures using magnetic circular dichroism spectroscopy and time-dependent density functional theory calculations.

It is generally agreed that sperms “swim” by beating or rotating their soft tails. However, a research team led by scientists from City University of Hong Kong (CityU) has discovered that ray sperms move by rotating both the tail and the head. The team further investigated the motion pattern and demonstrated it with a robot. Their study has expanded the knowledge on the microorganisms’ motion and provided inspiration for robot engineering design.

A research group has discovered a new gene that aids in the fight against type 2 diabetes. The gene, known as L-IST, reduces Selenoprotein P, too much of which increases insulin resistance, and can be increased through drinking tea.

Researchers at Osaka Prefecture University have established an approach to identify the orientation of molecules and chemical bonds in crystalline organic-inorganic hybrid thin films deposited on substrates using Fourier transform infrared spectroscopy (FT-IR) and polarized infrared light with a 3D-printed attenuated total reflectance (ATR) unit. This inexpensive method with laboratory-grade equipment quickly reaches the crystal-structure model of even extremely thin films of less than 10 nm.

Hokkaido University researchers have developed a simple method that converts existing generic polymers into luminescent polymers using mechanical force.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

Chemical rings of carbon and hydrogen atoms curve to form relatively stable structures capable of conducting electricity and more — but how do these curved systems change when new components are introduced? Researchers based in Japan found that, with just a few sub-atomic additions, the properties can pivot to vary system states and behaviors, as demonstrated through a new synthesized chemical compound.

The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a “weighted coin” that can favorably rig the odds to achieve outcomes where fertility is successfully restored.

No one knows what happened in the Universe for its first 400,000 years, but a new paper suggests discovering the hypothetical particle axion could shed light on the early history of the Universe. What's more, current dark matter experiments may have already detected it in its data.
