Artificial muscle as shock absorber

Engineers are working on intelligent materials that can diminish vibrations and extract power from the environment. These electro-active elastomers could dampen annoying vibrations in a car, for example, or supply wireless ...

Filming life in the fast lane

New microscope enabled scientists at EMBL Heidelberg to film a fruit fly embryo, in 3D, from when it was about two-and-a-half hours old until it walked away from the microscope as a larva.

Friction almost vanishes in microscale graphite

(Phys.org) -- In the phenomenon of superlubricity, two solid surfaces can slide past each other with almost no friction. The effect occurs when the solid surfaces have crystalline structures and their lattices are rotated ...

James Cook and the transit of Venus

Every ~120 years a dark spot glides across the Sun. Small, inky-black, almost perfectly circular, it's no ordinary sunspot. Not everyone can see it, but some who do get the strangest feeling, of standing, toes curled in the ...

STAR TRAK: June 2012

(Phys.org) -- The last transit of the planet Venus until 2117 will happen June 5 in the Western Hemisphere (June 6 in the Eastern Hemisphere). Venus will cross the face of the sun, appearing as a black dot on the sun's bright ...

First genome-wide assessment of secretion in human cells

(Phys.org) -- An international collaboration between scientists in University College Dublin and the European Molecular Biology Laboratory (EMBL) has revealed for the first time that 15% of the proteins encoded by the human ...
