Three tables showing rates of lung cancer among drinkers and non-drinkers, then adjusted for smokers and non-smokers
A scanning electron microscope image (a) of the nanoscale silicon mechanical resonator used in the laser cooling experiment. The outer "cross" patterning forms the shield while the central beam region, the SEM image of which is shown in (b), forms an optical cavity where laser light is used to cool the mechanical motion of the beam. Numerical simulations of the localized optical field and mechanical breathing motion of the nanobeam are shown in panels (c) and (d), respectively. Credit: Caltech/Painter, et al. For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting.
GENETIC sequencing will soon be cheap enough for everyone to have a digital copy of their own genome. But that also means someone could hack your hard drive or mobile device and gain access to it.
(PhysOrg.com) -- Want to find out how to Hunt the Higgs Boson using your phone? Ever wondered how the Large Hadron Collider experiments work, and what the collisions look like? Scientists at the world's biggest scientific experiment - the Large Hadron Collider (LHC)at CERN, Geneva - are trying to answer fundamental questions about the nature of the Universe, the origin of mass, the structure of space and time, and the conditions of the early universe . For those of us not lucky enough to have the world's highest energy particle smasher in our own back gardens, we can still get close to the action using an exciting new smartphone App.
Ankit Daftery is an engineering student at the Veermata Jijabai Technological Institute in Mumbai, India and he decided to take it upon himself to add the ability for the blind to type on an Android device.
In 1992, a shipping crate containing 28,000 plastic bath toys was lost at sea when it fell overboard on its way from Hong Kong to the United States. No one at the time could have guessed that those same bath toys would still be floating the world's oceans nearly 20 years later.
