Biologists at Lund University in Sweden have now shown that jackdaws minimise their energy consumption when they lift off

A silicone strain sensor glued to a rubber glove bends easily with the wearer’s finger. The amount of light transmitted by the fiber changes with the bending.

This is the reduction of CO2.

The discovery can lead to the development of efficient electrocatalysts for large scale production of

Because these so-called “mini brain organoids” mimic human brains in how they grow and develop, they’re

Their work is published by Proceedings of the National Academy of Sciences. Because wind speeds are higher

This image shows an energy diagram of the WSe2-MoSe2 device. When a photon (1) strikes the WSe2 layer, it knocks loose an electron (2), freeing it to conduct through the WSe2 (3). At the junction between the two materials, the electron drops down into MoSe2 (4). The energy given off in the drop catapults a

They use highly sensitive, nondestructive measurements to entangle the atoms, while maintaining their collective

But larger wind turbines also imply increased difficulties in inspecting them. Usually cranes and people are used to inspect both the rotor blade and the

To ensure these giants can reliably generate electricity for many years to come, the iron processing industry must manufacture their massive components in a stable,

Two overlapping lasers are helping Kansas State University physics researchers create holographic images of free-flowing air particles, which may help climate scientists and biological weapons watchdogs monitor what’s in the air.
