Ananalogy might be an expedition climbing Mount Everest. Is someone climbing Everest useful to you in everyday life? Not at first glance, no matter how interesting it is for its own sake. But fleece jackets and breathable waterproof fabrics were first developed for serious mountaineering expeditions and are now cheap and indispensable.

Particle physics has also made possible and advanced other treatment options, including accelerator-based therapy. Each year, tens of millions of patients receive X-ray, proton and ion therapy to treat cancer at more than 10,000 hospitals and medical facilities around the world.

Managed and distributed by Fermilab in collaboration with other labs and universities, Scientific Linux has been downloaded more than 10 million times, free of charge. Based on open source code provided by the company RedHat, Scientific Linux is used by researchers in laboratories and university groups around the world, including the one led by Akemi Matsuno-Yagi, a biologist at The Scripps Research Institute in California. Matsuno-Yagi depends on Scientific Linux for her research into one of the hottest areas of biology: molecular medicine.

Scientific Linux is not the only particle physics tool assisting this line of research. Across the Atlantic, a team led by United Kingdom Medical Research Council researcher Leonid Sazanov has spent years determining the atomic and molecular structure of Complex I using synchrotrons, the same kind of particle physics tools that were used to develop Kaletra and Tamiflu.

Take Jerome Friedman. Trained as a particle physicist at Berkeley Lab, Friedman went on to run the computation research group at SLAC and, eventually, to become a professor of statistics at Stanford University.

Through these and other lines of inquiry, particle physicists are learning how the most basic building blocks of nature work and interact. That not only allows us to understand the how and the why of the universe around us, but it also frees us to control those building blocks and develop new materials, new applications and new industries.

Matter & Interactions is a textbook by Ruth Chabay and Bruce Sherwood (John Wiley & Sons, 4th edition, 2015) that emphasizes a modern perspective on the calculus-based introductory physics curriculum taken by science and engineering students. It engages students in:

M&I is in use in large engineering and science courses at large and medium sized universities including Purdue University, Georgia Tech, Cal State Long Beach, North Carolina State University, the University of Mississippi, Carnegie Mellon, Minnesota State University Moorhead, Villanova, High Point University, and the University of West Florida. A number of universities including the University of Michigan use it in courses for honors students or physics majors.

The curriculum is also used outside the United States, including at the University of Cape Town, South Africa, Macquarie University, Australia, the University of Gothenburg, Sweden, and the University of Helsinki.

The Institute for Theoretical Physics (IFT), belonging to the Spanish National Research Council (CSIC) and the Autonomous University of Madrid (UAM), hosted this week the eighth edition of the IBS-MultiDark-ICTP workshop dedicated to the physics of dark matter. In collaboration with the MultiDark project, the event brought together 50 experts, including theoretical and experimental physicists, aiming to foster collaboration and the exchange of ideas in the pursuit of answers to the mysteries of dark matter.

The meeting comprised 25 talks covering a wide range of topics in the field of particle physics and cosmology. The high-energy physics group from ICTP joined the event, further strengthening the network of researchers dedicated to understanding dark matter. Additionally, the MultiDark project, a multimessenger approach to dark matter detection, consists of approximately 10 theoretical, experimental, and astrophysics groups from around 20 Spanish research institutions and universities. The Institute for Basic Science (IBS), comprises 40 centers, including three experimental and theoretical ones on particle physics and cosmology:

It is estimated that dark matter constitutes approximately 27% of the observable universe. The rest of the universe's content mainly comprises the matter we are familiar with (atoms and molecules), representing only 5% of the universe, and dark energy, accounting for approximately 68% and responsible for the accelerated expansion of the universe. After decades of research, its nature remains unidentified, posing one of the most intriguing open problems in physics.

Despite having detectable gravitational effects, dark matter neither emits nor interacts with light or electromagnetic radiation, making it impossible to observe directly with telescopes or other optical instruments. Thus, how do we study it? What tools can we use to attempt its detection?

Clues for identifying this intriguing form of matter may be found in particle accelerators such as the Large Hadron Collider or LHC at CERN. Sven Heinemeyer, a researcher at IFT and one of the coordinators of the workshop held in Madrid, highlighted the significance of investigating dark matter through the supersymmetry model in particle accelerators: "Excesses in LHC data that could be related to dark matter have been observed. We are working on interpreting these results in our model and comparing them with data from previous years to identify potential candidates to reveal the nature of dark matter."

Among the most innovative approaches stands out that of Jos Valle, from the Institute of Corpuscular Physics (IFIC), who is one of the speakers at the workshop. Valle addressed the connection between neutrino mass generation and dark matter: "Among the key problems in physics is the fundamental explanation of the universe's dark matter and neutrino oscillations. I have proposed the idea that neutrino mass generation (2015 Nobel Prize) may be connected to explaining dark matter. That is, dark matter could be what triggers neutrinos to have mass, thus explaining two enigmas at once," noted Valle.

In short, the combination of theoretical and experimental approaches aims to pave a promising path towards unraveling the enigma of dark matter, which constitutes a significant yet elusive part of the universe.

The Institute for Theoretical Physics (IFT) UAM-CSIC was officially created in 2003 as a joint research center belonging to the Spanish National Research Council (CSIC) and the Autonomous University of Madrid (UAM). It is the only Spanish center dedicated entirely to research in Theoretical Physics. The IFT members develop research in the frontiers of Elementary Particle Physics, Astroparticles and Cosmology, in order to understand the fundamental keys of Nature and the Universe. They are also leading many research projects, both at the national and international level. The IFT is part of the strategic line `Theoretical Physics and Mathematics of the Campus of International Excellence (CEI) UAM+CSIC established in 2009. Since 2012, it is credited as Severo Ochoa Centre of Excellence. Besides purely scientific activity, in the IFT is also conducted intensive training tasks of young researchers and professionals through the graduate program in Theoretical Physics with mention of excellence from the CEI and the Ministry of Education. In addition, the Institute carries out the important task of transferring knowledge to society through several outreach programs.
