Dr Peter Evans – Retro-Causality: Unravelling the Mysteries of Quantum Cosmology
Despite many years of research aiming to unite quantum mechanics with cosmological theories, researchers in fields across physics and philosophy remain in disagreement about a solution. Now, Dr Peter Evans at the University of Queensland sheds new light on the debate. He argues that on quantum scales, the idea of cause and effect does not need to follow the one-way passage of time, as we understand it. If correct, his theories could dispel some of the most puzzling mysteries of quantum theory – a significant step forward in understanding the true nature of the universe.
Dr Scot Rafkin – Exploring the Weather of Titan and Mars
The moons and rocky planets of our Solar System may be remote, unfamiliar worlds, but even on the very strangest of them, the weather on those with atmospheres is not wholly unlike our own. Dr Scot Rafkin, a planetary scientist at the Southwest Research Institute, believes that the small-scale patterns their atmospheres exhibit are directly comparable with Earth’s weather. Based on the results of computer models simulating the atmospheres of Titan and Mars, he argues that these local and regional behaviours are significantly underappreciated in planetary science.
CERN’s Future Circular Collider
Geneva-based particle physics research centre, CERN, plans to build a £20bn particle accelerator that is almost four times longer than today’s largest and most powerful accelerator, the Large Hadron Collider (LHC). At 100 kilometres long, this ‘Future Circular Collider’ (FCC) will be able to accelerate particles to unprecedented speeds, leading to collisions that are 10 times more energetic than those achieved on the LHC. Measurements taken from such collisions will help scientists in solving several longstanding mysteries in physics, such as the nature of dark matter. In this exclusive interview, we speak with CERN physicist Dr Matthew McCullough, who tells us about CERN’s plans for the FCC, its remarkable capabilities, and the new physics that he is most excited to explore.
TEMPO: Monitoring North America’s Pollution from Space
Created by sources ranging from campfires to cargo ships, air pollution is incredibly difficult to track. This has meant that the full impacts of air pollution are almost impossible to assess, but a solution is on the horizon. The TEMPO instrument (tempo.si.edu), built by Ball Aerospace to Smithsonian Astrophysical Observatory specifications and managed by the NASA Langley Research Center, will soon provide an all-encompassing view of pollution across North America. As part of a global constellation of satellite air quality missions, TEMPO will soon provide us with the most extensive view of pollution ever achieved, along with its impacts, allowing us to tackle it more effectively than ever before.
Jianguo Wang – Ion-Barrier Coatings: The Next Generation of Anticorrosion Technology
Corrosion, the gradual destruction of metals, is a significant physical and economic problem worldwide. Traditional heavy metal-based coatings used to protect metals are now viewed negatively due to their impact on the environment. Research led by Jianguo Wang of AnCatt Inc reveals why ion-barrier coatings are the next generation of anticorrosion coating technology.
Dr Nancy Chabot | Dr Carolyn Ernst | Ariel Deutsch – Icy Discoveries on Our Innermost Planet
The location of water in our solar system may hold the key to understanding how the planets evolved, and indicate other potential places to find life away from Earth. Dr Nancy Chabot and Dr Carolyn Ernst of Johns Hopkins University Applied Physics Laboratory, and Ariel Deutsch at Brown University, use data from NASA’s MESSENGER mission to understand how much ice exists on Mercury and how it may have arrived there.
Dr Liming Li – Exploring Energy Flow in Planetary Atmospheres
Within the atmospheres of different planets, energy is continually moving around and being converted into different forms. In his research, Dr Liming Li at the University of Houston studies how the different worlds of our solar system generate, transfer and convert energy in different ways. Through analysing the atmospheres of Jupiter, Saturn, Titan and Earth, his team has made discoveries that provide new insights both for astronomers and for scientists studying our own changing climate.
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.
