The paper explains how, thanks to their antioxidant and anti-inflammatory properties, cerium oxide nanoparticles have been able to partially reverse the cellular mechanisms involved in tumor progression and have managed to significantly increase survival in a rat animal model. [28] A biodegradable nerve guide embedded with growth-promoting proteins that can regenerate long sections of damaged nerves has been developed by researchers in the US. [27] Food and energy availability cause physical changes in acid-loving microorganisms that are used to study Earth's climate history, according to research from Dartmouth College. [26] A research team at the Massachusetts Institute of Technology (MIT) has designed medical devices that break down inside the body when they are exposed to light from an LED "pill". [25] An emerging technology involving tiny particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. [24] Two physicists from the University of Luxembourg have now unambiguously shown that quantum-mechanical wavelike interactions are indeed crucial even at the scale of natural biological processes. [23] Monika Aidelsburger uses a special type of optical lattice to simulate quantum many-body phenomena that are otherwise inaccessible to experimental exploration. [22] University of Illinois Professor Harry Hilton brought together several mathematical and physical theories to help look at problems in more unified ways and solve physical engineering problems. [21] A team of physicists from RUDN, JINR (Dubna), and the University of Hamburg (Germany) developed a mathematical model for describing physical processes in hybrid systems that consists of atoms and ions cooled down to temperatures close to absolute zero.
