FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the extraordinary efforts of Professor Warren to change a geology paradigm that probably helped explain the Cambrian explosion 600 million years ago, and how entrenched dogmas resisted his work. https://www.sciencedirect.com/science/article/pii/S0012825219302636?via=ihub View in LinkedIn

SHAPE OF THINGS TO COME. “Images of the Eagle Nebula show the Hubble Space Telescope's ability to capture pictures in both visible (left) and infrared (right) light. NASA is celebrating the successful restart of the telescope's payload computer, opening the door to more observations.”" " https://lnkd.in/ddZZNyaT View in LinkedIn

SENSES = BIOLOGICAL + CULTURAL. “Anthropological work focused on the senses is founded on the insistence that the senses are not merely a biological ground on which cultural meanings are constructed. Rather, the senses are always already fully cultural, and “sensory perception is a cultural as well as physical act.” https://lnkd.in/dTt-pFhv View in LinkedIn

SENSITIVITY NEEDED. “Antimatter particles in CRs represent a small fraction of the total flux, about 5 × 10(−3) for e+, 10(−5) for anti-p, 10(−7) for anti-D, less than 10(−8) for anti-4He or heavier antinuclei: these tiny fluxes, however, carry a great amount of information, since the origin of antiparticles is intimately related to fundamental processes.” (CR = cosmic rays). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

EXCITING NEW ERA. “During the last 25 years, these questions have been addressed with increasing accuracy and experimental performances by a number space experiments like AMS-01, PAMELA, AGILE, FERMI, AMS-02, CALET, and DAMPE.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

THE QUESTIONS. “The theme poses three fundamental questions: 1) What is the origin of the Matter-Antimatter asymmetry in our Universe? 2) What is the particle nature of Dark Matter and does it contribute to the cosmic radiation? 3) Which is the origin, the acceleration and the propagation mechanism of Cosmic Rays?” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

MACHINE 2.0. “A second generation, large acceptance, superconducting magnetic spectrometer proposed as mission in the context of the European Space Agency’s Voyage2050 long-term plan: the Antimatter Large Acceptance Detector In Orbit (ALADInO) would extend by about two orders of magnitude in energy and flux sensitivity the separation between charged particles/anti-particles, making it uniquely suited for addressing and potentially solving some of the most puzzling issues of modern cosmology.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

FINDING ANSWERS. “These developments started the era of precision Cosmic Ray physics providing access to a rich program of high-energy astrophysics addressing fundamental questions like matter-antimatter asymmetry, indirect detection for Dark Matter and the detailed study of origin, acceleration and propagation of CRs and their interactions with the interstellar medium.” (CR = cosmic rays). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

NEW TECHNOLOGY. “During the last 20 years, the advent space-borne magnetic spectrometers in space (AMS-01, Pamela, AMS-02), able to measure the charged cosmic radiation separating matter from antimatter, and to provide accurate measurement of the rarest components of Cosmic Rays (CRs) to the highest possible energies, have become possible, together with the ultra-precise measurement of ordinary CRs.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn
