A formal model called EMIF is introduced to represent life's interaction of these variables, offering a new perspective on physics.
Life is viewed as a structured system, not just a biological outcome, highlighting the importance of energy, mass, information, and feedback convergence.
The paper explores how life acts as a mechanism to understand the interplay of energy, mass, information, and feedback in shaping physical reality.
A theoretical framework is presented, defining life as a functional system driven by the variables of energy, mass, information, and feedback.
The paper delves into examples like photosynthesis to illustrate how energy, information, and feedback contribute to life's structure and function.
Feedback loops in systems play a crucial role in moving from quantum uncertainty to classical behavior in life-like systems.
An EMIF field is proposed where energy, mass, information, and feedback interact spatially and temporally to characterize physical systems.
The model suggests that life may emerge from the convergence of energy, mass, information, and feedback, offering a path for further empirical and mathematical exploration.
Predictions based on the EMIF framework are explored in areas such as quantum mechanics, cosmology, and artificial intelligence, providing insights into various phenomena.

When the physicists need burner phones, that’s when you know America’s changed | John Naughton

American academics are now traveling with 'burner' phones and minimalist laptops due to concerns about their safety and privacy in the US under the Trump administration.
Incidents like the deportation of Dr. Rasha Alawieh and attempts to deport Mahmoud Khalil have raised fears among researchers about the future of academic freedom in the US.
The Trump administration's targeting of universities and research funding further intensifies concerns about the autonomy of academic institutions.
The hostile stance towards universities in the US is likened to the actions of autocrats, with certain areas of research being particularly vulnerable.
There is a growing fear among teachers and researchers in the US about the restrictions on various fields of study, reminiscent of the intolerant atmosphere of the 1930s.
European universities are beginning to offer safe havens for American researchers facing challenges in the US, with initiatives like postdoctoral positions in France and Brussels.
These efforts to provide refuge for at-risk researchers highlight the changing dynamics of academic collaboration and support across different continents.
In contrast, UK institutions appear less proactive in addressing the challenges faced by American academics, indicating a potential shift in international academic relationships.
The article discusses the parallels between the current situation and the need to rescue Jewish scientists during the 1930s, emphasizing the importance of providing support and sanctuary for scholars in peril.
There are stirrings in Europe to establish secure environments for American researchers, showcasing a solidarity movement to protect academic freedom and knowledge exchange.
Overall, the evolving landscape of academic safety and research autonomy calls for global cooperation and support mechanisms to safeguard scholarly pursuits in an increasingly challenging environment.

Sterile neutrinos are a no-show (again)

New data from the NOvA experiment at Fermilab in the US show no evidence for "sterile" neutrinos, aligning with standard neutrino oscillation models.
Sterile neutrinos, a potential explanation for discrepancies in neutrino detections, have not been observed in NOvA's study.
Neutrinos exist in three flavours (electron, muon, tau) and oscillate as they travel, hinting at their nonzero mass.
Sterile neutrinos, which interact only via gravity, could impact our understanding of particle physics and dark matter.
The NOvA experiment's two detectors measured neutrino oscillation over a distance of 810 km, finding no oscillation into sterile neutrinos.
Comparing data to neutrino oscillation models, the researchers found no excess neutrinos suggesting the presence of sterile neutrinos.
Results are consistent with previous experiments like T2K, Daya Bay, RENO, and MINOS+, providing stricter limits on active-sterile neutrino mixing.
The NOvA team aims to reduce uncertainties and improve detection methods to further explore the potential existence of sterile neutrinos.
Co-spokesperson Patricia Vahle emphasizes the importance of checking for anomalies in neutrino studies and hints at further investigations.
The absence of sterile neutrinos in NOvA's findings contributes to the ongoing discourse on the elusive nature of these particles in particle physics.
