A new imaging biomarker for the aging brain


Enlarged ventricles is a sign of an aging brain. New research shows that this phenomenon can be predicted by lagging brain circulation that is detected by MRI.

Cancer cells killed with artificial glycosylated metalloenzyme


Scientists have developed two cancer therapies that use an artificial glycosylated metalloenzyme to specifically target cancer cells in mice.

Flies use fecal deposits as pheromones


Bioluminescence imaging of fly brains reveals neurons sensitive to fly poo laced with pheromones (you can see the fecal “landmark” in the dotted circle). Need we say more?

AdR blockers protect the brain from stroke damage


Treatment with adrenergic receptor antagonists (AdR blockers) was able to reduce stroke-related brain damage in mice and improve motor recovery.

Talking science Illustration with Misaki Ouchida


Whether it’s bird anatomy or science cartoons, Masaki Ouchida can do it all. She spoke with us about her career in science illustration, from the US to Japan.

Protein antigens in meat, milk, and other foods suppress gut tumors


Food antigens were found to prevent small intestinal tumors in gut-tumor prone mice by making ensuring we have enough T cells for defense.

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.

Running away from carbon dioxide: the terminal connection


Even fish want to avoid carbon dioxide. Now we know that they can because of chemosensation and the Terminal Nerve.

Toward human hibernation: cold-resistant mouse stem cells


Cold-resistant stem cells from “deep torpor” mice are a big step toward understanding why tissue survives hibernation.

Blue gene regulation helps plants respond properly to light


Blue light alters some gene expression in plants by changing the transcription start sites to downstream locations.

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.

Electric rays to help us map the ocean floor


Electric rays and sting rays could map the ocean floor through their natural behavior, helping us find resources and collect data on other ocean life.
