Nature inspires first artificial molecular pump
Using nature for inspiration, a team of Northwestern University scientists is the first to develop an entirely artificial molecular pump, in which molecules pump other molecules. This tiny machine is no small ...
Security experts sound medical device malware alarm
Artificial jellyfish 'Medusoid' swims in a heartbeat: Creation is an amalgam of silicone polymer and heart muscle cells
Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate ...

Glass electrodes used in nanoscale pump
Researchers create tiny pump that provides continuous and spontaneous antigravity water delivery
Ocean bacteria get 'pumped up': Team discovers new factors impacting fate of sinking carbon
The ocean has been sucking up heat-trapping carbon dioxide (CO2) building up in our atmosphere—with a little help from tiny plankton. Like plants on land, these plankton convert CO2 into organic carbon ...
Sodium pump could act as molecular light switch
Scientists from Jülich, Grenoble, Frankfurt and Moscow uncovered the atomic structure of KR2, a light-driven transporter for sodium ions which had only recently been discovered. Based on the structural information ...
Industrial pump inspired by flapping bird wings
Birds are unwitting masters of fluid dynamics—they manipulate airflow each time they flap their wings, pushing air in one direction and moving themselves in another. Two New York University researchers ...
Ocean food web is key in the global carbon cycle
Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to oceanographer David Siegel, director of the Earth Research Institute at ...
Liquid metal pump a breakthrough for micro-fluidics
RMIT University researchers in Melbourne, Australia, have developed the world's first liquid metal enabled pump, a revolutionary new micro-scale device with no mechanical parts.
Space suit issue prompts delay of second spacewalk
Astronauts removed an old space station pump Saturday, sailing through the first of a series of urgent repair spacewalks to revive a crippled cooling line.
Spacewalking astronauts make speedy station repairs (Update 2)
Two American astronauts made quick progress during a spacewalk outside the International Space Station on Saturday to replace a broken equipment cooling system, NASA said.
NASA: Cooling pump on space station shuts down
NASA said Wednesday it was looking into a problem with a malfunctioning cooling pump on the International Space Station, but there was no immediate danger to the two American astronauts, three Russian cosmonauts, ...
