Purple biomass makes a good crop fertilizer


Biomass made from purple marine bacteria provides more than enough nitrogen to plants without harming the environment

RIKEN Research Fall Issue


Fall is here, and with it comes the latest issue of RIKEN Research. This issue covers tactile learning during sleep, supercomputers and simulations, solar cells, fly olfaction, tumor vaccines, and more

New artificial skin helps avoid animal testing


A new artificial skin that reproduces proper tension can be used to research skin function and disease while reducing the need to experiment on animals.

Predictive grid cells help self navigation in the brain


Scientists have discovered grid cells in the brain that map an animal’s (or human’s) future position in space.

Stolen genes used for parasitic mind control


Parasitic horsehair worms evolved to control their praying mantis hosts by stealing their genes (horizontal gene transfer).

Black smokers and electroecosystems


Black smokers are deep-sea hydrothermal vents found in the ocean. Now scientists believe that they may host electroecosystems in which the primary producers use electric currents as their energy source.

Eve Marder: freeing knowledge, crashing neurons


None of us would get on a plane that had its parts changed in mid-air, says Eve Marder, who has spent her career probing a very specific cluster of crustacean nerve cells. Yet we are all walking around undergoing a constant turnover of cellular parts, and so are the lobsters and crabs Marder studies.

Learning and unlearning to fear: The two faces of noradrenaline


Fear association and unlearning fear association require different populations of noradrenaline neurons in the locus coeruleus.

Organ regeneration in the lab

Pulses of light can enhance superconductivity


Pulses of light could be used to turn materials into superconductors through an unconventional type of superconductivity.

Organic nitrogen in soil helps crop growth


Scientists used a multi-omics analysis to show that soil solarization helps crops grow because it increases organic nitrogen in the soil.

Eating a high fat diet without getting obese?


Scientists discover that without innate immune cells in the intestines, eating a high fat diet does not lead to obesity in mice.

New lab-grown retinal sheets almost ready for clinical trials


A new retinal transplant technique works by preventing bipolar cells from maturing in lab-grown retinal sheets.

Green hydrogen production for fuel cells and fertilizers


A new method of water electrolysis avoids rare metals, making hydrogen production green and sustainable.

Artificial gravity protects the immune system of mice in space


Mice who experienced artificial gravity on the ISS suffered less damage to their immune system (thymus) than weightless mice did.

The stars align

The stars align


The stars align. That’s what you say, when things work out perfectly. In the case of an eclipse, of course, it’s not stars that align but rather the moon and sun.
