Ultrafast imaging of complex systems in 3D at near atomic resolution nears

It is becoming possible to image complex systems in 3-D with near-atomic resolution on ultrafast timescales using extremely intense X-ray free-electron laser (XFEL) pulses.

Electric field switching of ferromagnetism at room temperature

In a development that holds promise for future magnetic memory and logic devices, researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and Cornell University successfully used an electric field to reverse the magnetization direction in a multiferroic spintronic device at room temperature. This demonstration, which runs counter to conventional scientific wisdom, points a new way towards spintronics and smaller, faster and cheaper ways of storing and processing data.

NASA to Discuss Today Asteroid Redirect Mission Capture Concept, Next Step in Journey to Mars

NASA will host a media teleconference at 4 p.m. EST today during which agency officials will discuss and answer questions on the selection of an Asteroid Redirect Mission concept.

What's next for the Large Hadron Collider?

The world's most powerful particle collider is waking up from a well-earned rest. After roughly two years of heavy maintenance, scientists have nearly doubled the power of the Large Hadron Collider (LHC) in preparation for its next run. Now, it's being cooled to just 1.9 degrees above absolute zero.

With collider set to reboot, physicists look beyond the Higgs

So much for the warmup laps. Harvard physicists are looking with anticipation to the spring, when the Large Hadron Collider (LHC) at CERN, Switzerland, fires up after a two-year hiatus for repairs and upgrades. The last time it was running, science celebrated the discovery of the Higgs boson, a long-sought elementary particle and the last one predicted by the Standard Model.

Physics professor publishes exact solution to model Big Bang and quark gluon plasma

Unlike in mathematics, it is rare to have exact solutions to physics problems.

Microwave imaging system promises better, cheaper breast images for cancer screening

Although currently available diagnostic screening systems for breast cancer like X-ray computed tomography (CT) and mammography are effective at detecting early signs of tumors, they are far from perfect, subjecting patients to ionizing radiation and sometimes inflicting discomfort on women who are undergoing screening because of the compression of the breast that is required to produce diagnostically useful images.

The simplest element: Turning hydrogen into 'graphene'

New work delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures.

Scientists trace nanoparticles from plants to caterpillars: Are nanoparticles getting in our food?

In one of the most comprehensive studies of its kind, scientists tracked uptake and accumulation of quantum dot nanoparticles from water to plant roots, plant leaves and leaf-eating caterpillars.

Exact solution to model Big Bang and quark gluon plasma

Scientists have published an exact solution that applies to a wide array of physics contexts and will help researchers to better model galactic structure, supernova explosions and high-energy particle collisions, such as those studied at the Large Hadron Collider at CERN in Switzerland.
