Novavax's vaccines utilize what are called virus-like particles--genetically engineered molecules designed to train the immune system to recognize a particular virus.
The danger from nuclear waste comes mainly from dust-like particles containing radioactive isotopes of iodine, cesium and strontium that could be released if the reactor fuel is allowed to become too hot.
Investors putting in buy and sell calls should then act a bit like particles in a glass of milk, which remain suspended because they are constantly bustling into one another in a process known as Brownian motion.
According to the standard model these six particles (the flavoured neutrinos and the corresponding electron-like particles) together with another six, the quarks (which make up the protons and neutrons in atomic nuclei), are the irreducible units from which the rest of matter is composed.
These are like the particles in the Standard Model - but more massive.
He saw that there was an analogy between the radiation in the container and a gas: The quanta, he realized, behaved like gas particles.
Producing antimatter particles like positrons and antiprotons has become commonplace in the laboratory, but assembling the particles into antimatter atoms is far more tricky.
The party-goers are the Higgs field, which gives mass to particles like electrons (Lady Thatcher) by viscously impeding their progress.
Particles like the Higgs have to be found indirectly, by hurtling them to near-light speed and then smashing them together to generate other subatomic entities.

That does not affect their electrical conductivity, but nanoscale particles like this are known to scatter and obstruct the passage of heat through imperfectly understood quantum-mechanical processes.
The outermost part of this layer prevents other particles, like dirt and grime, from binding to it.
Solgels are colloids, or liquids with uniformly dispersed solid particles (like milk) that are converted to gel form.
So Parks borrowed a tool common in the welding of plastic components, which is to gently agitate the hopper so that particles flow like water into a metering chamber.
But that would be possible only if they had mass and the standard model says that, like photons (the particles of which light is composed), they should be massless.
ECONOMIST: The news that neutrinos have mass is both good and bad
The Stratospheric Particle Injection for Climate Engineering project, or SPICE, is a British academic consortium that seeks to mimic the actions of volcanoes like Pinatubo by pumping particles of sulfur dioxide, or similar reflective chemicals, into the stratosphere through a twelve-mile-long pipe held aloft by a balloon at one end and tethered, at the other, to a boat anchored at sea.
Clusters like El Gordo release energetic particles that have an effect on the cosmic microwave background, the extremely faint glow left over from the Big Bang that permeates the Universe.
However, the cat (or, rather, subatomic particles that behave like the cat) has proved hard to hunt down in practice because such superpositions of states are fragile and easily disrupted phenomena.
Each electron added to this fluid creates a ripple, and these ripples behave like fractionally charged sub-atomic particles.
As a consequence, the wavelengths of the chilled atoms become very large (atoms, like everything else, are both particles and waves).
According to quantum theory, all particles are wave-like (and all waves particle-like).
It spreads like other respiratory viruses, through releasing viral particles from coughing and sneezing which then find new hosts in the general vicinity.
FORBES: Is a New SARS-like Virus Spreading in the Middle East?
Like other groups searching for possible dark-matter particles (such as axions and neutrinos), the best they can hope for at the moment is to narrow the field.
Without it, or something like it, some of the Standard Model's particles that actually do have mass (particularly the W and Z bosons) would be predicted to be massless.
When it is injected into muscle, the AAV particles are sucked up by the hand-like protrusions connecting muscles with the nervous system, all the way back up into the spinal cord.
If you were to assume that every point in the universe contained some information, then even a small office would be so densely packed with particles that it would collapse in on itself like a black hole, says Raphael Bousso, a physics professor at the University of California, Berkeley.
Yet at places like Bad Gastein in the Austrian Alps, visitors crave alpha particles as much as California spa goers clamor for seaweed wraps.
The Standard Model (see table) includes familiar particles such as electrons and photons, and esoteric ones like the W and Z bosons, which carry something called the weak nuclear force.
In 2004, the probe called Stardust swung by a comet called Wild 2, stuck out sort of a big catcher's mitt--I think it looks more like a tennis racket--and hopefully it picked up some of the particles thrown off by the comet.
When he shone a light up through it, he could see fine-grained particles of silica, known as chert, mixed in with what looked like coal.
