An analysis of more than 70,000 galaxies by University of California, Berkeley, University of Zurich and Princeton University physicists demonstrates that the universe – at least up to a distance of 3.5 billion light years from Earth – plays by the rules set out 95 years ago by Albert Einstein in his General Theory of Relativity.

A team of physicists headed by Christian Roos and Rainer Blatt from the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences realize a quantum walk in a quantum system with up to 23 steps. It is the first time that this quantum process using trapped ions is demonstrated in detail.

Materials such as paper, paint, and biological tissue are opaque because the light that passes through them is scattered in complicated and seemingly random ways. A new experiment has shown that it's possible to focus light through opaque materials and detect objects hidden behind them, provided you know enough about the material.

Most polymers — materials made of long, chain-like molecules — are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.

A worldwide team of researchers, including 10 from Texas A&M University, have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe – the so-called "Big Bang" – and it could lead to new questions and answers about some of the basic laws of physics because in essence, it creates a new form of matter.

Scientists at the University of Rochester have discovered that the Earth's magnetic field 3.5 billion years ago was only half as strong as it is today, and that this weakness, coupled with a strong wind of energetic particles from the young Sun, likely stripped water from the early Earth's atmosphere.

Dunes On Mars: How Sand Shifts Without Wind
It's a scientific mystery: How did dunes form on Mars when the wind doesn't seem strong enough to move the sand? Jasper Kok tells Guy Raz he may have the answer — it has to do with sand "bouncing" and "splashing" in a way that's different than what happens on Earth.
