Laser melting ice-core sampler for studying climate change


This laser melting ice core sampler can determine temperature changes thousands of years ago on very fine timescale.

Recipe for hydrogen: sprinkle manganese oxide with iridium atoms, add water


A few iridium atoms also go a long way. When sprinkled on manganese oxide, hydrogen is produced with 95% less iridium!

Cyborg microchip valve driven by earthworm muscle


This earthworm muscle-controlled biological microelectromechanical system (bio‐MEMS) could lead the way to next-generation medical implants.

Random movements help color-detecting cells form the proper pattern


Scientists have used a mathematical model to explain why zebrafish cone cells in the eye are arranged in a specific pattern in all individuals.

Hibernation-like state can protect kidneys during heart surgery


Activating Q-neurons in the mouse brain led to a hibernation-like state that protected kidneys during heart surgery.

Stolen genes used for parasitic mind control


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

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

Transgenic plants ??on acid survive without water


Scientists designed transgenic plants that survive drought-like conditions by bumping up acetic acid production only when water is scarce.

Why (mouse) mothers take risks to protect their infants


The calcitonin receptor and its ligand amylin act in the brain to motivate mouse mothers to protect their pups, even in risky/dangerous situations.
