RIKEN Research Spring issue is here


Just a quick post to let you know that the Spring issue of RIKEN Research Magazine came out towards the end of March. This issue covers issues including the discovery of element 113, earth-friendly pesticides, and the secrets of a rice-killing fungal toxin. Enjoy!

Supermassive black holes still dark and mysterious


For the first time, scientists have measured the strength of magnetic fields near supermassive black holes and something doesn’t add up.

Clean and green: a moss that removes lead (Pb) from water


Scientists show that the moss Funaria hygrometrica can remove harmful lead from water when in the protonema stage of development.

Genomic “butterfly effect” involving TADs explains risk for autism


De novo mutations in three-dimensional structures in the genome containing known ASD genes were found to be associated with ASD risk.

Ultraprecise clocks and the Tokyo Skytree verify Einstein’s theory of relativity


Time measured at the top and bottom of the Tokyo Skytree with ultraprecise clocks has verified the time dilation effect predicted by Einstein.

Albumin drops medicine off at cancer site then leaves the body


By changing albumin’s identity, drugs can carried to their targets and then removed from the body after being used.
