- Relic Abundance Of Stable Dark Energy May Be Less Than Thought
The amount of dark matter left over from the early universe may be less than previously believed. Research published in the open access journal PMC Physics A shows that the "relic abundance" of stable dark matter particles such as the neutralino ...

- Magnetic Properties Of Thin Films
Materials researchers at the National Institute of Standards and Technology (NIST), together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edge—literally—to produce the first data o ...

- Quantum Space-Time Dynamics
Quantum gravity can be understood by considering the logical consqquences of a single unifying postulate or principle of nature. I call it the postulate of quantized space time. First some observations. The Gravitational force seems to pervade the entire u ...

- Dark Matter Non-News That Still Somehow Merits A News Release
Dark matter is believed to exist in the form of tiny particles that do not interact with light. Because they don’t emit or reflect electromagnetic radiation the way atomic, or baryonic, matter does, these dark matter particles haven’t been directly observe ...

- Slowing Down Atoms
With atoms and molecules in a gas moving at thousands of kilometres per hour, physicists have long sought a way to slow them down to a few kilometres per hour to trap them. A group of physicists from The University of Texas at Austin have found a way to sl ...

- Mathematicians Make Liquid Defy Gravity
We are all familiar with raindrops on our wind screens. The small ones stay in place while the big ones roll down the window. This is because surface tension holds the small drops onto the screen until they get to a size where the force of gravity is great ...

- What Makes Quantum Dots Blink
Quantum dots have great promise as light-emitting materials, because the wavelength, or color, of light that the quantum dots give off can be very widely tuned simply by changing the size of the nanoparticles. If a single dot is observed under a microscope ...
