Dr Andreas Keiling – Alfvén Waves: When Earth’s Shield Comes under Attack
The Earth’s magnetic field has long protected us from surges of harmful charged particles originating from the Sun, yet physicists still don’t entirely understand what happens during this interaction. To explore the issue, Dr Andreas Keiling of the University of California at Berkeley studies the complex processes that take place during these so-called solar storms. His work has now begun to unravel the mysteries of the electromagnetic battleground far above Earth’s surface.
Dr Baowei Fei – A New Technique for Targeted Prostate Cancer Biopsies
Two-dimensional transrectal ultrasound (TRUS) guided biopsy is the standard method for prostate cancer diagnosis. However, the technique is limited in one respect – it can be prone to sampling error. Cancers can be missed, or their severity grossly underestimated. To address this, Dr Baowei Fei, from the University of Texas (UT) at Dallas and UT Southwestern Medical Center, is pioneering a technique that merges positron emission tomography (PET) with TRUS to detect prostate cancer more accurately than before.
