Video: What is Electricity?

Think about it for a minute. Do you really know what electricity is? Does anyone? What is electricity? Electricity is the set of physical phenomena associated with the presence and motion of electric charge. What is an electric charge? It is the physical property of matter that causes it to experience a force when placed… Read More »

ultra-rare “impossible” quasicrystal found in Russian meteorite

A quasicrystal’s atomic structure combines the symmetrical properties of a crystal and the chaos of an amorphous solid. Originating in outer space, these crystals aren’t just incredible because of how rare they are – their atomic structure is so peculiar, for decades their existence was dismissed as “impossible”, and they cost the scientist who first… Read More »

Video: Is Anything Real?

This video includes a nice explanation of what we currently think memories are: the result of strengthening of connections between nerve cells.

Oldest star in Universe discovered

Astronomers in Australia have found the oldest known star in the universe, a discovery that may re-write our understanding of the universe directly following the Big Bang. The team from Australian National University (ANU) say that the star, located around 6,000 light years away from Earth, is roughly 13.6 billion years old. This means it… Read More »

Carbon’s new champion: Theorists calculate atom-thick carbyne chains may be strongest material ever

Rice University researchers have determined from first-principle calculations that carbyne would be the strongest material yet discovered. The carbon-atom chains would be difficult to make but would be twice as strong as two-dimensional graphene sheets. (Image Credit: Vasilii Artyukhov/Rice University) Carbyne will be the strongest of a new class of microscopic materials if and when… Read More »

Research team confirms existence of Higgs boson elementary particle

An experiment conducted by an international research team has confirmed the existence of Higgs boson, which is widely believed to grant mass to substances in the universe, establishing the standard theory of the elementary particle. The team, comprising researchers from the University of Tokyo, the High-Energy Accelerator Research Organization and overseas research institutes, will announce… Read More »

German Scientists Freeze Light for a Minute

It turns out that the fastest known thing in the universe, light, can in fact be stopped. A German team of scientists have successfully stopped light from traveling for a whole minute. The record-breaking event could be a major breakthrough in the field of quantum memory storage. So how did scientists freeze light for a… Read More »

Researchers demonstrate “accelerator on a chip”

In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice. The achievement was reported today inNature by a team including scientists from the U.S. Department… Read More »

Scientists create never-before-seen form of matter

Harvard and MIT scientists are challenging the conventional wisdom about light, and they didn’t need to go to a galaxy far, far away to do it. Working with colleagues at the Harvard-MIT Center for Ultracold Atoms, a group led by Harvard Professor of Physics Mikhail Lukin and MIT Professor of Physics Vladan Vuletic have managed… Read More »

Theoretical Element 115 Exists, Study Confirms

Researchers confirm the existence of this synthetic element in a new accelerator study. Will it be enough to give ununpentium official recognition and a new name? At the bottom right corner of the periodic table of elements, there are a handful of boxes that illustrators often color gray. The International Union of Pure and Applied… Read More »
