Watching quantum mechanics in action: Researchers create world record laser pulse

A research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action -- something that has been hidden from view until now.

Every atom counts in graphene formation: Nanoreactor theory could advance quality of material’s growth

Researchers detail the atom-by-atom energies at play in the chemical vapor deposition process of creating graphene.

Using magnetism to understand superconductivity

Research in atomic scale magnetism could play a role in the development of new materials that could permit lossless electricity transmission.

Guest Post: Doug Finkbeiner on Fermi Bubbles and Microwave Haze | Cosmic Variance

When it comes to microwaves from the sky, the primordial cosmic background radiation gets most of the publicity, while everything that originates nearby is lumped into the category of “foregrounds.” But those foregrounds are interesting in their own right; they tell us about important objects in the universe, like our own galaxy. For nearly a decade, astronomers have puzzled over a mysterious hazy glow of microwaves emanating from the central region of the Milky Way.

NASA Announces Asteroid Naming Contest for Students

Students worldwide have an opportunity to name an asteroid from which an upcoming NASA mission will return the first samples to Earth.

NASA Is Expanding Offer For Space Shuttle Tiles And Food

NASA is expanding its offer to museums and schools of space shuttle heat shield tiles and food packaged for spaceflight.

BNL's researchers help connect nuclear science and nanoscience for safer reactors

Following last year's earthquake and tsunami at Japan's Fukushima nuclear power plants, many nuclear scientists have been focused on developing models to predict what will happen under a variety of conditions that may exist at similar facilities around the world.

Non-equilibrium quantum states in atmospheric chemistry

(Phys.org)—Research that sheds new light on the microscopic chemical physics driving one of the most important reaction sequences in atmospheric chemistry is published in Science today by Dr David Glowacki from the University of Bristol's School of Chemistry, in collaboration with an international team including experimentalists and theoreticians based in Leeds, Cambridge, and Chicago.

Animal Consciousness | Cosmic Variance

At the Francis Crick Memorial Conference in Cambridge last month, a collection of internationally recognized experts on consciousness took an unusual step, as science conferences go: they issued a declaration (pdf).

New single-shot X-ray technique makes magnetic image

(Phys.org)—Scientists working at SLAC's Linac Coherent Light Source have captured the first single-shot X-ray microscope image of a magnetic nanostructure and shown that it can be done without damaging the material.
