Leaf-inspired surface prevents frost formation

Northwestern University researchers discovered a new way to significantly reduce frost formation on any surface. The finding could help decrease the amount of energy needed for de-frosting and could potentially result in ...

Predicting 50,000 years of bird migrations

Neither wind, nor rain—nor massive sheets of ice—have kept Earth's birds from their appointed rounds of migrating to better climes, according to a new study.

Fish simulations provide new insights into energy costs of swimming

A new computational analysis suggests that maximizing swimming speeds while minimizing energy costs depends on an optimal balance between a fish's muscle dynamics and the way its size, shape, and swimming motion affect its ...

Would a carbon tax help to innovate more-efficient energy use?

Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new paper published in Joule from Carnegie's Rong Wang (now at Fudan University), Harry Saunders, and Ken Caldeira, along ...

Researchers use AI to plot green route to nylon

The chemical and allied industries face such challenges as ready access to reliable energy supplies, waste reduction, water conservation, and energy efficiency. Organic electrosynthesis—an electricity-driven, energy-efficient ...

Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car ...
