RIKEN is a large natural sciences research institute in Japan. Founded in 1917, it now has approximately 3000 scientists on seven campuses across Japan, the main one in Wako, just outside Tokyo. RIKEN is an Independent Administrative Institution whose formal name is Rikagaku Kenkyusho. RIKEN conducts research in many areas of science, including physics, chemistry, biology, medical science, engineering and computational science, and ranging from basic research to practical applications. It is almost entirely funded by the Japanese government, and its annual budget is approximately 88 billion yen (US$760 million).
Femtosecond 'snapshots' reveal a dramatic bond tightening in photo-excited gold complexes
Metal complexes are becoming increasingly important as the photochemical building blocks of functional molecular systems such as sensors and photoelectrochemical cells. Of particular interest are metal complexes ...
Bringing life into focus
Spinning-disk confocal microscopy is an optical imaging technique that can be used to generate detailed three-dimensional fluorescence images of living cells and their contents. Although a powerful tool for ...
Scientists use X-ray diffraction to image whole, hydrated cells in their natural state for the first time
Most cells exist in a hydrated state and often live suspended in solution. In order to be imaged, cells must generally be frozen or dried, and then stained with substances such as heavy metals. Unfortunately, ...
Subset of short genes hidden inside plant genomes may be important in setting plant growth patterns
Although thousands of entire genomes have been sequenced, our understanding of their detailed workings remains far from complete. Researchers continue to find new genes, determine their function, and map ...
Capturing light in an efficient dye trap
Chemical compounds that can efficiently capture and convert light energy are in high demand as key components of inexpensive solar cells and advanced optical sensors. Carbon-based organic dyes are particularly ...
X-rays in the fast lane
X-ray free-electron lasers (XFELs) produce higher-power laser pulses over a broader range of energies compared with most other x-ray sources. Although the pulse durations currently available are enormously ...
The changing phase of quantum materials: Theoretical model could aid search for ideal material for quantum computers
Matter is categorized as either conductive, semi-conductive or resistive to the flow of electrons based on its bulk properties. However, physicists have now predicted a new state of matter in which the bulk ...
A liquid crystal force to reckon with
A need for fast, solution-based processing of organic electronic devices has sparked increased interest in 'discotic' or disc-shaped liquid crystals. These molecules, which contain a flat aromatic core surrounded ...
Intriguing state of matter previously predicted in graphene-like materials might not exist after all
Virtually every material undergoes atomic-level ordering when cooled to temperatures approaching absolute zero. Liquid water, for example, is frozen into atomically ordered crystalline ice. However, condensed ...
Finding the missing genes in hormone-biosynthesis pathway hints at subtle control of growth in rice
The plant hormones known as gibberellins (GAs) are growth promoters that are involved in a wide range of processes from seed germination to flower development. The details of the biosynthesis of GAs, however, ...
New imaging technique to visualize bio-metals and molecules
Metal elements and molecules interact in the body but visualizing them together has always been a challenge. Researchers from the RIKEN Center for Life Science Technologies have developed a new molecular ...
Clever use of high-resolution mass spectrometry allows rapid cataloging of sulfur-containing compounds in plant extracts
Plants are a rich resource of bioactive compounds, many of which have inspired therapeutic drugs. Yet countless plant compounds, potentially with medical uses, still remain to be identified. Kazuki Saito, ...
High-powered microscopic techniques give scientists detailed view of a critical component of cellular infrastructure
The cellular interior is criss-crossed by protein-based cables known as microtubules, each formed from 13 'protofilaments' composed of the protein tubulin. Microtubules are also associated with a host of ...
A vertebrate family reunion
By demonstrating the close 'relatedness' of two primitive jawless fish, scientists begin to assemble a more accurate depiction of the early history of vertebrate evolution.
RIKEN BioResource Center to provide seeds of model cereal plant
Seeds of the model cereal plant Brachypodium distachyon are now available at the RIKEN BioResource Center (BRC) in Japan, the second bioresource facility to provide seeds of this important model plant to the ...
