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 ...
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 ...
Tapping into mine water for geothermal energy
Millions of miles of tunnels criss-cross the ground under old mining communities across the United States. Abandoned, falling apart and choked with water, the tunnels are often viewed as a dangerous legacy. ...
Dryers: Homes' energy guzzlers just got greener
For the first time in six years, Energy Star certification, a standard seal of approval for energy efficiency, has been expanded to include another major household appliance.
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 ...
Researchers describe structure of the largest protein complex in the respiratory chain
Mitochondria produce ATP, the energy currency of the body. The driver for this process is an electrochemical membrane potential, which is created by a series of proton pumps. These complex, macromolecular machines are collectively ...
Keeping hackers out of hospitals
The humble infusion pump: It stands sentinel in the hospital room, injecting patients with measured doses of drugs and writing information to their electronic medical records.
Hot showers, lower power bills with heat pump water heaters
How much energy was used to heat the water for your morning shower is probably the least of your groggy, uncaffeinated thoughts.
City OKs plan for gas-pump climate change labels
Climate-change warning labels are coming to gas pumps in Berkeley, California, a city with a long history of green and clean policies.
Filling up could cost less thanks to biomolecular engineering breakthrough
Sticker shock at the gas pump could soon be a thing of the past thanks to research being conducted by UT and Oak Ridge National Laboratory.
Pumping efficiency into electrical motors
(Phys.org) —University of Adelaide researchers are using new magnetic materials to develop revolutionary electrical motors and generators which promise significant energy savings.
Research shows how plant welfare is improved by fungi in soil
A University of York biologist is part of an international team of scientists that has discovered how plants use fungi to help them to gather vital nutrients from the soil.
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 ...
