New technique excites atoms and molecules using pulsed laser
The best method to obtain the most precise information on the inner structure of atoms and molecules is to excite them by means of resonant laser light. Unfortunately, just this laser light (above a certain ...
'Lab-on-a-chip' to accelarate, enhance medical testing, researcher says
(Phys.org)—Suppose you are sick enough to go to an emergency room. A physician examines you and decides that some blood tests are warranted. A phlebotomist draws the blood and sends it to a lab for testing. ...
Electromagnetic cloaking possible with ordinary plastic, study finds
A metal object can be made invisible with the help of ordinary plastic, Pekka Alitalo and Constantinos Valagiannopoulos, researchers from the School of Electrical Engineering, have shown in their study.
Spacetime ripples from dying black holes could help reveal how they formed
(Phys.org)—Researchers from Cardiff University have discovered a new property of black holes: their dying tones could reveal the cosmic crash that produced them.
