Quantum Dots Can Penetrate Skin Through Minor Abrasions
Researchers at North Carolina State University have found that quantum dot nanoparticles can penetrate the skin if there is an abrasion
Feds preview long awaited mathematics reference
The National Institute of Standards and Technology (NIST) has released a five-chapter preview of the much-anticipated online Digital Library of Mathematical Functions (DLMF).
Mystery molecule opens door to quantum computing semiconductors
The odd behavior of a molecule in an experimental silicon computer chip has led to a discovery that opens the door to quantum computing in semiconductors.
Is energy the ability to do work?
Some school physics books say that energy is the ability to do work. But isn't work the amount of energy transferred?

Cloak of silence realized with metamaterials
Researchers in Spain have proven that metamaterials, materials defined by their unusual man-made cellular structure, can be designed to produce an acoustic cloak - a cloak that can make objects impervious to sound waves, literally diverting sound waves around an object.
Mathematics and gravitation theory
The physical ambiguity of mathematics in gravitation theory has led to an overextension of the mathematics and resulted in theoretical misdirection.

Physicists Produce Quantum-Entangled Images
Using a convenient and flexible method for creating twin light beams, researchers at National Institute of Standards and Technology (NIST) have produced “quantum images,” pairs of information-rich visual patterns whose features are “entangled,” or inextricably linked by the laws of quantum physics.
Lensing and algebra: Where mathematics and astrophysics meet
The mathematicians were trying to extend an illustrious result in their field, the Fundamental Theorem of Algebra. The astrophysicists were working on a fundamental problem in their field, the problem of gravitational lensing.
Early universe to spill beans on secrets of fundamental physics?
The future of fundamental physics research lies in observing the early universe and developing models that explain the new data obtained. The availability of much higher resolution data from closer to the start of the universe is creating the potential for further significant theoretical breakthroughs and progress resolving some of the most difficult and intractable questions in physics.

The Falling Galaxies within the Finite Universe.
The size of the universe is determined by the laws of nature. Where these laws end, at the boundary, the universe ends, space itself ends - nothing can exist beyond the border. All the matter and energy that strike the boundary are absorbed. At the same time new massless matter is created to replace the absorbed matter.
