Physical interpretations of the time-symmetric formulation of quantum mechanics, due to Aharonov, Bergmann, and Lebowitz are discussed in terms of weak values. The most direct, yet somewhat naive, interpretation uses the time-symmetric formulation to assign eigenvalues to unmeasured observables of a system, which results in logical paradoxes, and no clear physical picture. A top–down ontological model is introduced that treats the weak values of observables as physically real during the time between pre-and post-selection (PPS), which avoids these paradoxes. The generally delocalized rank-1 projectors of a quantum system describe its fundamental ontological elements, and the highest-rank projectors corresponding to individual localized objects describe an emergent particle model, with unusual particles, whose masses and energies may be negative or imaginary. This retrocausal top–down model leads to an intuitive particle-based ontological picture, wherein weak measurements directly probe the properties of these exotic particles, which exist whether or not they are actually measured.

DNA produces a metamaterial stronger and lighter than steel. Desiccants reduce HVAC system energy use. And fungi is turned into concrete.

There are an estimated 30,000 instances of arc flash each year in the United States alone, and one to two fatalities occur daily in North America. Ontario Power Generation (OPG) has five Boston Dynamics’ Spot robots deployed throughout their Enterprise Innovation division. In 2022, the team sought to see if Spot’s dexterous arm could be used to assist in tripping and racking out a 600 volt breaker—an activity that is high risk for arc flash. Now, Boston Dynamics engineers have taken this application to the next level by fully automating the procedure. Spot can perform the entire operation autonomously, with a human issuing high level commands safely out of harm’s way.

Even with the quantum rules governing the Universe, there are limits to what matter can withstand. Beyond that, black holes are unavoidable.

Astronomers used the Hubble Space Telescope to determine that a nearby exoplanet is losing its atmosphere due to interactions with its star.

Webb is casting the universe in a new light, but the space telescope’s discovery of a cosmological question mark has us scratching our heads.

New breakthrough in material design will help football players, car occupants, and hospital patients.

A significant breakthrough in the field of protective gear has been made with the discovery that football players were unknowingly acquiring permanent brain damage from repeated head impacts throughout their professional careers. This realization triggered an urgent search for better head protection solutions. Among these innovations is nanofoam, a material found inside football helmets.

Thanks to mechanical and aerospace engineering associate professor Baoxing Xu at the University of Virginia and his research team, nanofoam just received a big upgrade and protective sports equipment could, too. This newly invented design integrates nanofoam with “non-wetting ionized liquid,” a form of water that Xu and his research team now know blends perfectly with nanofoam to create a liquid cushion. This versatile and responsive material will give better protection to athletes and is promising for use in protecting car occupants and aiding hospital patients using wearable medical devices.

Industrial condition monitoring sensors collect data that facilitates intelligent decisions via machine learning or AI to predict machine failures and increase productivity.
