Researchers conducted a 3 year continuous high-speed imaging observation at Poker Flat Research Range, Alaska, USA, and identified the physics behind the flickering of aurora. At the same time, they ...

After more than 40 years of intense research, experimental physicists still seek to explore the rich behavior of electrons confined to a two-dimensional crystalline structure exposed to large magnetic ...

Photo: Four-inch copper-encased cyclotron, one of Ernest Lawrence's ealiest models When Ernest Orlando Lawrence (1901-1958) got his PhD in physics, the hottest topic was bombarding the atom's nucleus ...

The controls are to the left and the cyclotron is to the right with shields closed. View Slideshow Albert Swank Jr., a 55-year-old civil engineer in Anchorage, Alaska, is a man with a mission. He ...

Temperature is an awkward concept for a single particle, but the energy of the particle's 'quivering' is a useful substitute. Feedback control of this motion can be used to cool a single electron to ...

Zevacor Molecular, a healthcare firm that manufactures PET and SPECT radiopharmaceutical products, installed the first and largest commercial 70-million electron volt (MeV) cyclotron dedicated to ...

Theranostic radiopharmaceuticals are molecules that can safely carry radioactive isotopes inside targeted human tissues and help physicians get accurate images of tumours, allowing them to more ...

Cyclotron – it sounds like a character from a science fiction film. It’s actually a particle accelerator, a machine that uses electromagnetic fields to propel charged particles to very high speeds and ...

One morning this month, George Hamawy, Columbia University’s director of radiation safety, stood before a group of students crowded into a basement laboratory and delivered a eulogy for one of the ...

The word "aurora" invokes an image of a slowly shimmering curtain of light illuminating the sky. However, when an explosive aurora occurs, known as a breakup, it sometimes leads to another phenomenon ...
