We recently saw research that suggested negative radiation pressure in light could lead to a practical tractor beam.

As the name implies, it's all based around pressure: a light touch performs the usual commands, while squishing the thumb's wider surface area against the screen allows the equivalent of a multi-touch gesture, such as a pinch to zoom.
It stayed away from a high pressure zone with light winds off Nova Scotia, and built up a big enough lead to withstand the challenge from Silk Cut which was in the right place to benefit from the conditions in the second half of the leg.

To make them sensitive to the deflection caused by pressure, the researchers carved grooves in the fibres along their length so that the bouncing of the light was less efficient at the point where pressure was applied.
Andrews can show that it's more than just theory: the two have successfully created an optical field that flipped the usual pressure and started pulling objects toward the light.

They are the fingers and eyes and noses of the computer, bringing the world (be it a car crash, pressure in a fuel line, or light in a fiber-optic network) into the boxed, insular space that sits quietly on desktops.
In their latest experiment, Dr Sullivan and his colleagues painted the blades of a rotor with both temperature-and pressure-sensing paints, shone laser light on to them, and mapped out the temperatures and pressures as the blades whirred around as fast as 14, 000 rotations per minute.
Sensors that understand everything from temperature, light and moisture to motion, pressure and stress, need to be connected.

If his speech succeeded in blunting US pressure on Israel - even temporarily - on the Palestinian front, and in light of the results of the Iranian presidential race, Netanyahu has gained the opportunity to act on the Iranian front.
After a brief unboxing, this editor wrapped each set around his head, finding the headband tension of both the over-ear N11 and the on-ear NLa to be just as light as the accessories themselves, squeezing my skull with only the gentlest of pressure.
