Getting to the heart of frustrated magnetism

Thin films of helium atoms with nuclei of two protons and one neutron—helium-3—intrigue physicists because they have exhibited unusual and unexpected magnetic behavior in experimental investigations.

A genetic alternative to fertilizer

Several studies have shown that a lack of nitrogen in soils adversely affects crop yields. The modern use of nitrogen fertilizers has improved yields to meet expanding global food demand, but in some cases up to 50% of the ...

Simplifying long-range quantum interactions in many-body systems

Calculations for certain quantum systems whose parts interact over long distances will be much easier to perform thanks to the work of a RIKEN physicist and his collaborator, who have extended an assumption that holds for ...

Resonant tunneling diode oscillators for terahertz-wave detection

A semiconductor device that is promising for both generating and detecting terahertz radiation has been demonstrated by physicists at RIKEN. This may aid the development of high-performance integrated solutions for terahertz ...

First mouse, now human, lab-grown eye tissue

Producing retinal tissue from human embryonic stem cells is now possible thanks to a team of researchers led by Yoshiki Sasai of the RIKEN Center for Developmental Biology in Kobe, Japan.

Japan scientists make see-through mice

Researchers at the RIKEN Quantitative Biology Center in Japan, together with collaborators from the University of Tokyo, have developed a method that combines tissue decolorization and light-sheet fluorescent microscopy to ...

A self-powered heart monitor taped to the skin

Scientists have developed a human-friendly, ultra-flexible organic sensor powered by sunlight, which acts as a self-powered heart monitor. Previously, they developed a flexible photovoltaic cell that could be incorporated ...

Fast and sensitive flu tracking

A practical means of tracking pandemic flu in the field—using an assay known as RT-SmartAmp—was developed recently by a research team in Japan led by Toshihisa Ishikawa at the RIKEN Omics Science Center, Yokohama. ...

Thin film reveals origins of pre-superconducting phase

RIKEN physicists have found an ideal platform for exploring the behavior of electrons in a material as it approaches superconductivity. This could help to develop new superconductors that operate at more convenient temperatures ...

Pretreating soil with ethanol protects plants from drought

Ethanol can help plants survive in times of drought says a new study conducted at the RIKEN Center for Sustainable Resource Science in Japan. Led by Motoaki Seki, researchers show that adding ethanol to soil allows plants, ...
